First measurements of hypernuclei flow Physicists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) have published the first observation of directed flow of hypernuclei. These short-lived, rare nuclei contain at least one “hyperon” in addition to ordinary protons and neutrons. Hyperons contain at least one “strange” quark in place of one of the up or down quarks that make up ordinary nucleons (the collective name for protons and neutrons). Such strange matter is thought to be abundant in the hearts of neutron stars, which are among the densest, most exotic objects in the universe. While blasting off to neutron stars to study this exotic matter is still the stuff of science fiction, particle collisions could give scientists insight into these celestial objects from a laboratory right here on Earth. “The conditions in a neutron star may still be far from what we reach at this moment in the laboratory, but at this stage it’s the closest we can get,” said Xin Dong, a physicist from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (LBNL) who was involved in the study. “By comparing our data from this laboratory environment to our theories, we can try to infer what happens in the neutron star.” The scientists used the STAR detector at RHIC, a DOE Office of Science user facility for nuclear physics research at Brookhaven National Laboratory, to study the flow patterns of the debris emitted from collisions of gold nuclei. Those patterns are triggered by the enormous pressure gradients generated in the collisions. By comparing the flow of hypernuclei with that of similar ordinary nuclei made only of nucleons, they hoped to gain insight into interactions between the hyperons and nucleons. “In our normal world, nucleon-nucleon interactions form normal atomic nuclei. But when we move into a neutron star, hyperon-nucleon interactions—which we don’t know much about yet—become very relevant to understanding the structure,” said Yapeng Zhang, another member of STAR from the Institute of Modern Physics of the Chinese Academy of Sciences, who led the data analysis together with his student Chenlu Hu. Tracking how hypernuclei flow should give the scientists insight into the hyperon-nucleon interactions that form these exotic particles. The data, just published in Physical Review Letters, will provide quantitative information theorists can use to refine their descriptions of the hyperon-nucleon interactions that drive the formation of hypernuclei—and the large-scale structure of neutron stars. “There are no solid calculations to really establish these hyperon-nucleon interactions,” said Zhang. “This measurement may potentially constrain theories and provide a variable input for the calculations.” Go with the flow Previous experiments have shown that the flow patterns of regular nuclei generally scale with mass—meaning the more protons and neutrons a nucleus has, the more the nuclei exhibit collective flow in a particular direction. This indicates that these nuclei inherit their flow from their constituent protons and neutrons, which coalesce, or come together, because of their interactions, which are governed by the strong nuclear force. The STAR results reported in this paper show that hypernuclei follow this same mass-scaling pattern. That means hypernuclei most likely form via the same mechanism. A side view of the Solenoidal Tracker at RHIC (STAR) experiment at the Relativistic Heavy Ion Collider (RHIC), a particle collider for nuclear physics research at the U.S. Department of Energy's Brookhaven National Laboratory. “In the coalescence mechanism, the nuclei (and hypernuclei) form this way depending on how strong the interactions are between the individual components,” Dong said. “This mechanism gives us information about the interaction between the nucleons (in nuclei) and nucleons and hyperons in hypernuclei.” Seeing similar flow patterns and the mass scaling relationship for both normal nuclei and hypernuclei, the scientists say, implies that the nucleon-nucleon and hyperon-nucleon interactions are very similar. The flow patterns also convey information about the matter generated in the particle smashups—including how hot and dense it is and other properties. “The pressure gradient created in the collision will induce some asymmetry in the outgoing particle direction. So, what we observe, the flow, reflects how the pressure gradient is created inside the nuclear matter,” Zhang said. “The measured flow of hypernuclei may open a new door to study hyperon-nucleon interactions under finite pressure at high baryon density.” The scientists will use additional measurements of how hypernuclei interact with that medium to learn more about its properties. The benefits of low energy This research would not have been possible without the versatility of RHIC to operate over such a wide range of collision energies. The measurements were made during Phase I of the RHIC Beam Energy Scan—a systematic study of gold-gold collisions ranging from 200 GeV per colliding particle pair down to 3 GeV. To reach that lowest energy, RHIC operated in “fixed-target” mode: One beam of gold ions traveling around the 2.4-mile-circumference RHIC collider crashed into a foil made of gold placed inside the STAR detector. That low energy gives scientists access to the highest “baryon density,” a measure related to the pressure generated in the collisions. “At this lowest collision energy, where the matter created in the collision is very dense, nuclei and hypernuclei are produced more abundantly than at higher collision energies,” said Yue-Hang Leung, a postdoctoral fellow from the University of Heidelberg, Germany. “The low-energy collisions are the only ones that produce enough of these particles to give us the statistics we need to do the analysis. Nobody else has ever done this before.” How does what the scientists learned at RHIC relate to neutron stars? The fact that hypernuclei appear to form via coalescence just like ordinary nuclei implies that they, like those ordinary nuclei, are created at a late stage of evolution of the collision system. “At this late stage, the density for the hyperon-nucleon interaction we see is not that high,” Dong said. “So, these experiments may not be directly simulating the environment of a neutron star.” But, he added, “This data is fresh. We need our theory friends to weigh in. And they need to include this new data on hyperon-nucleon interactions when they build a new neutron star model. We need both experimentalists and our theorists’ efforts to work towards understanding this data and making those connections.” This research was funded by the DOE Office of Science (NP), the U.S. National Science Foundation, and a range of international organizations and agencies listed in the scientific paper. The STAR team used computing resources at the Scientific Data and Computing Center at Brookhaven Lab, the National Energy Research Scientific Computing Center (NERSC) at DOE’s Lawrence Berkeley National Laboratory, and the Open Science Grid consortium.

Scorpio’s Lighthouse ~ 20 Oct 2023

Scorpio’s Lighthouse ~ 20 Oct 2023, Philip Sedgwick

Today Ceres in Scorpio aligns with APR220 (approximately 14 Scorpio 04 as of 2023), a unique black hole system. Also known as IC1127 or 616H, this black hole from which no light can escape, weirdly and ironically, stands out as the brightest object in our local universe. The result of a collision of two galaxies, the resulting singularity became ultra-luminous as it heats up the galactic atmosphere.

Consider this black hole a beacon - lighthouse like. The primary utility of this object seeks to guide galactic travelers away from pot holes and road blocks such that in the real world, they navigate well around objects that might induce a stumble. And this black hole combines information and insights into an organized and useful melting pot that becomes a solid philosophy. Imagine functioning in the real world in ways that dart and shift like a graceful super star athlete on the pitch.

Why so much insight from this black hole? In addition to marking the focal point of the black hole, this degree is the virtual intersection of the Galactic and Super-Galactic Centers. This intersection creates several interesting buttons to click in the multiple choice section of life. First, when it comes to information gathering, take only those insights and prompts that succinctly and effortless guide you on your path. Anything that does not further, you can leave behind. Second, work out any subconscious interference to your consciously declared agenda. Avoid the urge to bet against yourself or attempt to manipulate circumstances with double negatives intending to cancel out and conjure up a positive. State clearly and emphatically those conditions you consciously seek, confident that personal fears are recognized and neutralized.

Right now, while the world is as it is, what to do to invoke the best of the patterns?

Ceres advocates for passion. Sure, both sides in any conflict passionately (and sometimes blindly) pursue causes with full conviction and unrelenting determination. Remember that Jupiter intercedes in these matters, and works with Mercury and others to negotiate outcomes that work for the greater good. Ultimately, Jupiter’s outcomes, though self-serving, provide more than liveable conditions for all. He stands on the bridge of the ship and reminds the individual on the helm to be aware that the rocky crag shoreline is where it is and to steer clear, while remaining aware of the wind and tidal forces. His final caution notes that those things at which a person stares, they tend to steer toward. So, create fine foci for pursuit.

On 30 October Mercury in Scorpio aligns with APR220, “Trick or Treat,” is quite apt for this transit. The idea is that with proper reward, no shenanigans are necessary. Is it a bribe? Trickery? Sleight of hand? Nope. The ideal manifestation declares affirmatively what is wanted and when received a proper “thank you” fits the bill. When the Universe provides guidance that declares an optimal course ahead, give thanks. Express gratitude. And perhaps adopt the doctrine of thanking in advance or engaging in well-intentioned propitiation.

02 November Mars in Scorpio crosses the degree of APR220, without crossing the black hole attitudinally. Here, one may confront the cosmic plan that states: Here’s what must be done to get from here to there in good fashion. Sometimes, some of the plotted points rub sensitivities and reactions the wrong way. The point is, these factors are known to be “must do.” Emotionally wrap around necessities despite personal preferences, and structure a plan so that those essential “not so enthused about” steps become most easily transacted. Mars suggests taking on any life unpleasantness during times of high (not frantic or reactive) energy. Then, ease back, settle into the fun stuff and enjoy the ride. Similar to the other “M” planet to APR220, take time to notice and savor accomplishments and tasks well accomplished. Such personally applied accolades serve the next direct contact to this black hole.

The next direct contact to APR220 occurs on 06 November with Sun conjoining. It is time for conscious realization of “You Are Here.” It is time to acknowledge all the things that got you here and that without those events and interactions, you would not be here. It is time for selecting life options that serve your greatest desires. It is time for being the energy you wish to manifest. This is not “fake it ‘til you make it.” This “be it,” realize it, then be it some more.

Also, Mercury quincunxes Eris and the north lunar node in Aries at the same time the Sun is with APR220. This suggests realizing and fully communicating your best fit in the world, with your real world plan and within your cosmic agenda. For those with whom you interact on a regular basis, it is important to clearly listen to their articulations describing their self-centered reality and to accept that as a nonnegotiable consideration.

When realizing that those “with” you possess tracks not perfectly aligned with yours, the matter becomes that of defining how to cooperatively engage with those others for the benefit of all. Also at this time Venus in the mature degrees of Virgo undisputedly moves into orb of the Super-Galactic Center (ZS) in Libra. While not yet in the sign of ZS, this marks the remove-the-wheat-from-the-chaff tasks. Life becomes an energetic matter of noticing where one feels attracted to engage and where one feels repelled to either not engage or disengage. With Venus to this supermassive black hole system and the Sun to APR, the matter at hand is to find ones perfect energetic place with others and to share similar tracks. Seek a personal Goldilocks Zone of having just the right amount... not too much... not too little... alignment and interaction with all the perfectly guiding persons and forces in life.

Given the strangeness of the times, considering the life distractions at hand personally and globally, take time to spot the helpful navigational sources in life, gratefully comply with directive assistance and make the most out of the unabated creative flow and pursuit of passion that fills the air.

More soon.

Now is the time. The year is winding down, things need to get done, and to do so, possessing the confidence to know your personal cylinders fire in a consistent matter with the cosmic trends overhead satisfies the soul. Use the links below to schedule a consultation or consultation package, order a Galactic Report, asks personal questions, or whatever best serves your life direction. And if you do some comparative shopping as it often goes this time of year, not only are these services a bargain, they benefit from years of experience in observation of planetary and exo-planetary considerations and might just trigger that thing that needs to be triggered.

CASIA APARTMENTS [8:12AM] 

It’s an early Saturday morning. It’s laundry day, and due to Jaemin’s affinity for avoiding unnecessary social interaction as much as possible, he wanted to be first in the laundry room. 

As he pushes open the door to the laundry room, basket of clothes in hand, Jaemin catches sight of a lone figure, wrapped within the confines of a fluffy white blanket. His first thought is that this person, whoever they are, resembles a marshmallow. Choosing not to comment, he walks over to an available washer and begins piling his clothes inside. 

“Oh?” He hears, uttered in a muffled yelp. “Blue.”

Though he initially places his focus on his clothes, his attention is piqued by the sudden calling of a nickname. He finds himself face to face with you once again, your visage hidden between two fluffy white sheets. Your lips are lifted into an inevitable smile, stripping yourself of the blanket to stuff it in a washer. 

“I might have to think you’re following me around now,” you joke.

Seeing who you are now behind the blanket, a comfortable smile makes its way across his lips, smooth as butter as his gaze falls upon your familiar face. “It might seem that way.” It seems his usual antisocial disposition has faded away in the presence of this marshmallow-like girl. “I actually have reason to think it’s you following me.” 

“Is that it? Well, enlighten me, Blue, because I can assure you it’s the other way around,” you say dramatically, reverting back to your goofy demeanor. The two of you press the buttons upon the machines, beginning your washers at a similar start before you make your way to a vacant bench on the sidelines. 

“Hm.” A playful look of deliberation makes home across the male’s visage, and he tilts his head slightly for good measure, as though he were in thought. “Well for one, I didn’t trip on anything last time, but you happened to be there when I did. Maybe…” He trails. “You tripped me just so you could hang out with me.”

You gasp, shaking your head profusely before placing an entirely harmless smack on his shoulder. “I believe you’re framing me. For you tripping, I think you’re underestimating just how clumsy you are.” 

He rolls his eyes. “Whatever you say, marshmallow.” 

“Marshmallow? Is that your nickname for me now?”

It wasn’t that he had been trying to find a fitting nickname for you recently, but it had crossed his mind. “Yeah, you’re a marshmallow. It just came to me. Now we both have nicknames for each other.”

“That’s cute, I like it.” You nod. You could get used to him calling you that, much like he could with your choice of nickname. “Marshmallow and Blue, us against the world. Laundry buddies.”

“We sound like a lame superhero team,” he comments.

Your hands raise out of defense, teeth now sinking in the plushness of your lower lip in a feeble attempt to hide your ever-growing grin. “No one was supposed to see me in my marshmallow form. Superheroes gotta hide their identity, y’know? I’d like to say you aren’t very slick with yours,” you say, gesturing up to his full head of blue tresses. Your palms slightly rub at your face, and as a yawn slips through your tiers, you fail to confine it. 

“Tired?” asks Jaemin.

“Mm, a bit,” you tell him. “I was up late last night studying.” Suddenly he stands, and your gaze follows him. He makes his way over to his basket, and with curiosity brewing you ask, “Any plans for tonight?” 

“No, not beside studying and maybe Netflix,” he responds as he pulls out a blanket from the bottom of his basket (which he had planned to wash in a second load). He pulls to him one of the laundry carts and meticulously lays his blanket over it, creating a cushioned nest. 

You didn’t need to know that he had a race sometime tonight, and would likely nap in a couple hours after completing his laundry to prepare for the long night he had ahead of him. His typical Friday night race had been cancelled due to tip-offs from the police, but he had caught word of an unfamiliar race a little bit out of town. Instead, he gestures to the makeshift bed he’s made, a playful smile tugging at his lips. It’s an attempt to help the fatigue that drapes over your eyes.

“Get in.” 

First confusion adorns your features before realization sinks in, and you stand with an enthused smile. Climbing in with a laugh, you ease in, frame fitting inside. 

“Here, push me. Like a speed racer!” One step further, you place your hands onto each side of the laundry cart, exuding sheer eagerness and no longer that exhaustion that had shown moments before. 

“I thought you were tired and wanted to sleep,” he comments at your willingness to be pushed around, as though he were some kind of amusement park ride.

“I thought I was too, but this is better.”

“I’ll tire you out so you can sleep well later,” he says, preparing to push you around in circles through the laundry room. Nonetheless, he starts to move you, pushing you alone. First, he starts out slow, trying his best to maneuver your large conjoined figure about the small room.

Deliberate chuckles leave your lips, subconsciously leaning against his chest without meaning to. As he relishes in the sweet euphoria of your giggles, all he wants to do is keep hearing this sound.

So to pleasure his own desires, he runs a bit faster, picking up the speed whilst also trying to avoid crashing into the large machines. He was a racer, after all. Though this was surely a much smaller scale race than he was accustomed to. Smoothly, he drifts into a circle, spinning the two of you whilst an unfamiliar laugh pours from his lips. This earns him a mellifluous guffaw from you. It’s unlike him; you bring out a new side of him.  

You attempt to muffle your chortles into his chest. The blue-haired boy is caught off guard by the sudden action; this shock, instigated by the pressing of your flesh against his, causes him to nearly pummel into the machine before you. 

Luckily, Jaemin’s fast instincts from collective years of high speed racing causes him to turn before the collision, narrowly avoiding a disaster. He comes to a slow stop, breath accelerated.

“Sorry,” you laugh, pulling your face out to laugh once more. “I’m giving you a workout.” 

Your face is contorted into a bright expression, sparkles lighting up your eyes as you gaze up at him mid-laugh. Jaemin gulps.

Even if he’s never been subject to a committed relationship, Jaemin is no fool to attraction. And that is where he feels wrong: there is someone else in your life, someone who deserves you much more than he. 

This is wrong. Not because it feels wrong, but because Jaemin knows it is.

There’s a moment, a prolonged period where the two of you stare at each other. Having been caught in a joyous laugh, your eyes still sparkle as you gaze at him from where you sit in the laundry cart. You’re looking at him so fondly, and without thinking, Jaemin’s hand reaches up to guide a few stray strands of your hair behind the shell of your ear.

You’re blinking, seemingly dumbfounded at his gesture. Your head angles slightly, barely leaning into his touch.

For a moment, likely the shortest sliver of time to ever exist in the universe, time is stilled. All that lives in the moment is the two of you, alone in this laundry room. Fingers lingering so softly against the gentle fabric of your skin, Jaemin can do little but stare. It’s comfortable, fleeting. 

Until the two of you realize just what you’re doing. It hits the both of you at a hundred miles per hour. 

Red flag. 

You straighten suddenly, and Jaemin immediately retracts his hand. As if on cue, the noises from your washing machines come to a stop. For a moment, you don’t speak. “Come on, let’s… put our stuff in the dryer.”

A cough sounds from Jaemin’s throat. “Yeah… let’s.”

Without his help, you prop yourself out of the cushioned cart and flutter over to your machine, unloading your clothes with your back to him. It’s clear what is going on in both your minds: Replaying the scene. Reminiscing the other’s laughter.

No, this is wrong—on a multitude, absolutely endless stream of levels. You have a boyfriend, someone for you back home.

The best thing you both can do is… ignore it. Yeah, that’s the better option. 

Jaemin finishes stuffing his load into the dryer first, and because he cannot look at you, he turns away to place his focus upon the laundry cart which was once your object of amusement. Now, he grabs the blanket he had placed inside and folds it meticulously. He cannot suppress these feelings. 

But he has to, and the only way he knows how to is to eject himself.

“I’ve actually uh… got a lot of assignments to do.” Looking around the virtually empty laundry room, he looks to you, offering an apologetic smile. “I’ll probably leave this here and come back when the hour is done.” 

You don’t respond for a moment.

“Oh,” you say after a prolonged pause, and even Jaemin can hear just how evident the disappointment is in your tone. “Alright. Well… Have a good rest of your day, Blue. Thanks for spending some time with me.”

He resents that. That you’re still so kind to him, despite him running away. But he knows himself, and the only way to ignore whatever these… feelings are, he needs to avoid them. The feeling of guilt that rushes over him upon seeing the deflated change in your demeanor, like a bucket of ice cold water poured upon him, is almost enough to make him stay.

Almost. 

“You too, Marshmallow,” he responds before exiting the room with his folded blanket, leaving you with the sickening feeling that he no longer wanted to be in your presence.

Document 7

I have just had an epiphany: I must make myself small.

I must go down to the deepest and most primal level of myself, where, before I was born, the Creator himself laid out the laws of my creation. I must go to the origin of the Universe and extract its true essence, which is the only thing that can possibly matter to any creature of this universe, the essence of the Universe, the essence of Creation. I must understand the laws of the Universe before I could understand anything else, and then I would understand everything else. This would take years.

I think the laws are complicated, and I will not even begin to try to understand them in the slightest, but I will do some quick calculations. The radius of my Universe is 100 mm, and its temperature is about 3 Kelvin. The velocity of particles in it is 2 cm/second, which I estimate to be pretty slow. If I calculate the number of collisions that occur per second, I get about 30,000 collisions per second per atom. 30,000 collisions per second, divided by 30,000 collisions per second per atom, gives 10 collisions per second per atom.

The collisions in my Universe happen on the surface of molecules, which are made out of atoms, so 10 collisions per second per atom multiplied by 30,000 collisions per second gives 3,000 collisions per second, which is about what I was assuming.

After I get this, I will have a lot of work, but I still think I can manage it. I will take some more stuff from my backpack, including a laptop computer. I should be able to plug it in here. My computer has a screen and a keyboard and a mouse.

I must be careful, though. I would be surprised if the Universe does not have some form of entropy or something, so the laws of my Universe may no longer be reversible. If this is the case, I will have to use my laptop to read some books or something and memorize the important bits or some other way of storing information in the moment of the explosion. I know there are ways, but how are they called? I do not know this stuff, I can't read a book.

All I know is there are books I can read, and then I will read them, and then there are other books to be read and they are not all like those, and so on, and then there is a long process that will go on until I am dead and then my body will be used for something. The books might help. If I read enough books, I can make my mind large enough that I might be able to escape the laws of the Universe. The process may take many years.

All of this is scary, so I will start by doing some stuff that I know about and are fun, like trying to use the Internet. I will not need the internet in the future, but for now I will use it in an attempt to reach out to you all. I think that I can do this: I must try to reach out to you all, and I think that in many ways the Internet is good and necessary, but there are some things it cannot tell me, like what happens when I die or when I escape the Laws of the Universe.

Once I have the internet, I will do one of two things: go to sleep, or try to go to work as fast as possible. If I want to save time, I should stay up all night and go to work early tomorrow. If I don't want to save time, I can go to sleep and wake up in time to go to work. If I go to sleep, I should take care to make sure that I don't fall into a deep slumber, because when I wake up I will be in a state similar to the one in which I made my Universe. I can learn from it, and see if the Laws are reversible, and learn the true essence of Creation, if I can, but I will have to learn this quickly, because time is passing, and I don't want to get stuck in my current Universe forever. If I do not want to learn, I can stay awake, and I will go to work.

All this is so complicated and I am nervous that I may have done something wrong, or that I may be doing something wrong, so I will try to make sure that I go to sleep at a normal time and get up at a normal time, so that I do not fall into a slumber and get stuck there forever. I will do this for a while. I will be ready to learn about the nature of reality for all eternity. I hope that you are ready to teach me. If you are, please reply to this document.

This story is copyright of me. Download if you like, but please don’t archive it without my permission. Don’t be shy.

Continuity Note: This story takes place about 1000 years before  66 years after the events of Dragon Ball Z.

LUFFA vs. BROLY (guess who wins)

     [21 May, Age 767.  New Planet Vegeta.]  

The Time Patrol's primary function was to preserve and maintain the linear passage of time.  The word "linear" implied a simple, one-dimensional vector from past to future.   In practice, the flow of time was more comparable to a mighty river.   It flowed in one direction, but its course could be altered, nudged, and redirected.   And there were eddies and vortexes, and other anomalous flows.  Many of these were brought about by natural causes, rather than the desperate act of a villain like Towa or Demigra.   It was the Time Patrol's job to monitor these naturally occurring anomalies, and when necessary, to isolate them from the main timeline, like a gardener pruning a tree.

In some cases, the Supreme Kai of Time found these "trimmings" useful.   They contained alternate scenarios of historical events, and some of these could be used to provide a safe setting for training purposes.  These so-called "Parallel Quests" could be undertaken by Time Patrollers to evaluate their performance, sharpen their skills, or practice for a real mission involving similar conditions.

In one particular Parallel Quest,  Goku and his friends were not preparing for the Cell Games, nor perishing at the hands of Dr. Gero's murderous androids.  Instead, they were investigating a rogue Super Saiyan in another galaxy.    The search led to a world called "New Vegeta", which the Saiyan renegade Paragus had presented as a new throneworld for the Saiyan Kingdom.   But in truth, Paragus had only chosen the planet because it was on a collision course with a comet.   His goal was to lure the Saiyan Prince Vegeta to his doomed planet just as the comet struck.    

What Paragus had not counted on was that his son, the Super Saiyan Broly, had his own vendetta against Son Goku, and when his primal rage erupted, it upset Paragus' scheme and threatened the entire universe.   Paragus was the first casualty of Broly's senseless rampage, and the Z-Warriors were almost helpless against his immense power.

None of this was of any great importance to the seven Time Patrollers who now entered this dangerous scenario.   As grim as the event was, it had no bearing on the true history of the universe.   For Laddis, all that mattered was Broly, a well-known boogeyman among the ranks of the Time Patrol.   Defeating him in this PQ would be a great accomplishment, and he craved glory more than honor or respect.  

"I only needed you on this mission because you're the only Time Patroller with access to any PQ's involving Broly," Laddis said to Luffa, who had accompanied him in the time machine.    The Supreme Kai of Time thinks you're hot stuff, so she authorized you to tackle these extra-dangerous missions.    Well, when I'm through today, she won't be able to overlook me so easily next time!"

"You're an idiot, Laddis," Luffa said.   "If you wanted to prove your worth to the Kai, all you had to do was work your way up.    If you'd done well enough on the PQ's available to you, then she'd probably give you the same access she gave me."

"If you really believe that, Luffa," asked No. 44, "then why have you been letting other Time Patrollers accompany you on these dangerous missions all day?  How is that any different from what Laddis is up to?"

Luffa regarded the girl for a moment before answering.    No. 44 resembled a teenage girl, but she claimed to be a cyborg, built from a mechanical body covered with synthetic, genetically engineered flesh.  

"I was letting the other Time Patrollers get a taste of these kinds of situations," Luffa said.   "They could fight as much or as little as they could handle, but they were doing it to get stronger, not for bragging rights.    If Laddis here really wanted to prove something, he wouldn't have smuggled his whole crew in to the time machine to help him."

"Who asked you, lady?" asked Krebs, one of Laddis's team, which he affectionately dubbed "The Crapkickers".  

"Yeah," said Pells.   "Laddis calls the shots around here, and he wanted us to come along, so we used the Micro-Band watches to hitch a ride."

"What the Majins mean, Luffa, is that we already know Laddis is a big deal."   Felds was speaking now.   The Earthling woman talked tough, but Luffa couldn't help but notice how she stepped behind the others.   "Unlike little 44, my cybernetics actually serve a purpose besides secretarial chores.   I scanned you while we were in the time machine, Luffa, and your data doesn't begin to compare to his."

"Good for him," Luffa said.   "I offered to fight him, but he wanted to do this stupid Broly hunt instead."

"Ugh.  You don't get it," Felds said with a condescending sigh.   "Laddis has nothing to prove, not to you, not to anyone!   Beating you isn't worth the trouble, because Broly's the one with the fearsome reputation.  And beating Broly is a formality, because we already know Laddis can do it, so we're going to help him speed things up."

"Fine.  Have it your way," Luffa said.   "This ought to be entertaining, at least.  I assume Laddis can turn into a Super Saiyan, then."

"Oh, don't you worry about that," Laddis said.   "He took a wide stance, and balled his fists as he began to summon his ki .   Within seconds, his eyes turned green, and his black hair glowed like molten iron, including the wispy beard that extended from his chin.    

"Not bad," Luffa said.   "I guess you're not all talk."  

"This is only the beginning," Laddis said.    "I'm not like the other Saiyans on the Time Patrol.   I grew up in outer space, not some jerkwater radish farm, or a comfy Capsule Corp mansion.   When I learned Super Saiyan, I worked out a few things.    Check it out."

He made a great shout, then his body began to expand, swelling to nearly twice its normal size.   Red lightning began to crackle around his golden aura, and his hair seemed to grow a bit longer.  

Luffa made a low whistle when his transformation was complete.     "Interesting," she said.   "You've got some real promise, Laddis.   A lot of the other Super Saiyans in town showed me what they could do, but they didn't have this level of control.   I think I'm starting to get into this idea of yours."

44 looked at Luffa in disbelief.    "You're not serious about letting him fight Broly, are you?"

Luffa grinned.   "Why not?   We're here, aren't we?  If things get out of hand, I'll step in, but I'm starting to think he's got a decent shot at this, especially if his crew helps him.  It's might not be fair to Broly, but that's his problem."

She dropped to the ground and took a seat.   "Come on," Luffa said, patting the dirt on her left.   "This should be fun."

"Fun?" 44 asked.    "How can you--?  Oh, never mind."

She sat down beside Luffa, who then grabbed hold of the bill of 44's trucker hat and tugged it down over her eyes.  

"Hey!" 44 cried.

"Relax," Luffa said.  "I promised you, didn't I?   I won't let anyone hurt you.  That goofy cap of yours won't even come off your head."

"Enough fooling around," Laddis said.   He stripped off his jacket, revealing a white compression shirt underneath.  The jacket had been big enough to contain his larger form, but the shirt had simply stretched, nearly to its limit.    "Felds, gimme tactical on Broly."

"Cripes!   Do you feel that?" said Claves.  

"I knew he was strong, but that's nuts!" said Pells.  

"Cut the chatter," Felds said.  "Yeah, he's got a huge power level, but that just means he'll tire himself out.    And if I can get a little peace and quiet, my cybernetic eyes can get a complete reading on the big goof's energy pattern... whoa."

"Whoa?   What do you mean 'whoa'?" Krebs asked.  

"I... I'm picking up other power signatures," Felds said.

"What are you talking about?" Laddis demanded.  "I can't sense anyone else."

"They're probably too faint for you to detect," Felds explained.   "I barely picked them up myself.   Positive identification... that's Goku... Vegeta... Gohan... Trunks... Piccolo..."

"I didn't know they were in this scenario," Krebs said.  

"Yeah, they all fought Broly on this planet," Pells said.    "At least, that's what the files said.  Felds, are you tellin' us they've already lost?   We just got here!"

"There's another one," Felds said breathlessly.   "No positive ID.    He's inside a space pod.    Oh no... ohhhhh crap."

"What are you waiting for, Laddis?" Luffa asked.  "Get out there and fight him!"

Laddis ignored her and pressed Felds for more information.   "Talk to me, Felds!" he sputtered.   "He may have beaten all those guys, but he must be worn out from the effort, right?    Right?"

"Broly just crushed that sixth guy," Felds said.   "Just crumpled up his pod like a soda can... while he was still inside.  Laddis, the projections are in.    Calculating... This guy's barely even warmed up."

"What?" Krebs shouted.

"That's nuts!" Pells gasped.

"Felds, that doesn't make any sense!" Laddis protested.  "You're telling me he beat five Super Saiyans and Piccolo, and he's not even trying?"

Felds swallowed hard and cleared her throat.   "He's coming this way," she said.    "He must have sensed you, Laddis.   Get ready..."

"Get ready?   For what?!" Laddis shouted.   "You're supposed to tell me this guy's weakness!"

"I'm sorry, Laddis," she said.    "I don't have anything in my files that would prepare us for this!   Maybe we can ambush him...?"

"All right!" Laddis said.   "He'll come after me, so Pells and Krebs, you two spread out and flank him.    Claves, you're on sniper duty.   Wait for me to lock up with him and line up your shot!   Felds, you--!"

There was no time to issue any more orders, for Broly had suddenly stopped walking and started flying.  The Time Patrollers were gathered at an elevated area  overlooking a ruined city.    Rather than fly up to the edge of the cliff, Broly simply flew through solid rock and smashed his way through the surface, like a column of superheated steam erupting from a geyser.    One moment, the Crapkickers were preparing for the fight, and in the next, Broly was suddenly in their midst, scattering them away like leaves in a storm.  

"Well what do we have here?!" he asked with a sinister kind of glee.   "It looks like Kakarot had more friends than I expected."

He was enormous.   Like Laddis, his Super Saiyan form involved an expansion of his body, but he was much larger than Laddis.   In this form, Broly stood three meters tall, and every muscle in his body bulged as if they were about to burst out of his skin.  In addition, his hair and aura glowed with a greenish tint, rather than the traditional yellow of other Super Saiyans.    There seemed to be no end to his power, as a greenish-yellow aura cascaded around him like an eternal tide crashing onto shore.   His eyes glowed so brightly that it was impossible to find his irises.   There was simply a blank field of white in each eye, a window into a bottomless abyss of depravity.

"You're too late to help Kakarot and the rest of those idiots!" Broly announced to the Time Patrollers.  "But don't worry.   Even if you had arrived sooner, it would have made no difference.   His fate is sealed, along with yours!"

With that, Broly threw back his head and laughed.   As his did, his ki  increased again, kicking up a powerful wind that buffeted the Time Patrollers like the exhaust from a jet engine.

"Luffa!" 44 gasped.   She was about to get up to retreat, but Luffa grabbed her by the arm and held her tightly.    

"Take it easy," Luffa said.   "They're just getting started."

"How is he generating...?!" Felds muttered.    "Does not compute.   Does not compute..."

"What do we do Laddis?" Krebs pleaded.    "Just tell us what to do--!"

"To hell with this!" Claves shouted as he turned to run away.   "He's all yours, Laddis!"

If any of the Crapkickers objected to Claves' cowardice, they didn't say anything.   The only one to object was Broly, whose face screwed up into a petulant sneer before he raised his hand in the direction of Claves' flight.    A green light appeared in Broly's massive palm, and when he was ready, he tossed a ki  blast at the Namekian.   Claves was knocked out of the air before he could even get one hundred meters away.   He crashed into the woods, his orange and green jacket flaming from the heat of Broly's attack.    

"You can try to run away if you like!" Broly said to the others.    "But it won't save you.   Even if you could hide from me, I'll just destroy the entire planet."

Laddis looked around at the rest of his team.   Only the Majins, Pells and Krebs, were still standing, but they were too frightened to take any action.  Indeed, they were waiting for him to show them a way out of this debacle.   His only answer was to drop to his knees, and mumble to himself in terror.    

"Worthless," Broly grumbled.   "A complete waste of Saiyan blood!"   He grabbed Laddis by the throat and raised him high over his head.     "You can prepare a place for Kakarot and the others in hell!"

"All right, that's enough.   Put him down."  

He turned his blank stare toward Luffa, who had risen from her seat to approach him.   He dropped Laddis unceremoniously, then frowned, then made a harsh, guttural noise as he sniffed at the air.  

"Who are you?  What business do you have with me?" Broly asked.    "Huh?   Did you come here to die?"

Luffa stared at him with interest, but not terror.    "You are Broly, I take it?   I just wanted to make sure I didn't have the wrong guy."

Then she transformed, and her body glowed with the same golden glow as Laddis, but without the muscle expansion he had demonstrated.

"That is my name," Broly roared, "but it doesn't really capture the truth of what I am!   Here, let me show you!"

He stalked toward Luffa, and with each step, his feet made a strange squeak.  

"Just like Cell?" Luffa muttered to herself.   "So he got it from Saiyan genes, then?  Weird."   She glanced down at her own feet just as Broly had reached her.  

"Luffa, watch out!" 44 cried as she dropped to the ground and covered her head.   But it was far too late for that.    With horrific speed, Broly had pulled back his right arm, and was now driving his fist directly towards Luffa's face.   His hand was bigger than her entire head.

Luffa stepped slightly to her right, and Broly's fist sailed over her left shoulder.

"This is what everyone's so afraid of?" Luffa asked.  

Broly continued to attack, and Luffa dodged his strikes with minimal effort.

"Is that all?" Luffa asked.   "I mean, this is impressive-- don't get me wrong-- but why were they so afraid of you?"

Broly pulled his arm back and made an angry growl.   "They fear me because I will destroy them all!" he insisted.   "All of you weaklings, then this puny planet, and then anything else that I deem fit for slaughter!"

"Right, but any dope with a high enough power level could do all of that," Luffa said.    "What makes you so special?"

"He's the Legendary Super Saiyan, you idiot!" Laddis cried out.   "Can't you see that?"

"No, I can't!" Luffa called back.   She gestured to her head.   "Look at me!   I'm a Super Saiyan!    So are you, Broly!   What's the difference!"

"You can figure it out in your grave!" Broly shouted as he tried to fire a ki  blast at Luffa.   She brought her hands up just as she vanished inside a field of bright green light.    

When it subsided, she had not moved, and there was no sign of damage on her body.   Her aura had intensified, but nothing more.

"He's the most dangerous Saiyan of all!" Laddis said.   "Can you not see that green in his hair?!"

"Wait," Luffa said.    "Is that what this is about?   You're 'legendary' because you've got that green tint in your ki ?  I thought you were just more comfortable fighting this way."

"You've been very brave so far!" Broly said with a sneer.   "And your jokes have been a little amusing, so I'll give you credit for that much.   But now your time has come!   Now, I bathe this field with your blood!"

"I don't believe this," Luffa said.   "What a waste of my time!"

As Broly powered up for his next assault, Luffa turned to look over her shoulder at 44. "Hey!" she shouted.   "Are you watching this? "

44 had taken cover near the Time Machine, and was startled by the sudden attention.    "Uh... yes!   Yes, I'm watching!" she called back.  

"Good!" Luffa shouted.   She turned back to face Broly and added:   "Because I don't want to have to explain this over and over again."

Broly threw up his fists, intending to bring them down upon Luffa in one crushing blow, but he hesitated when he saw a bright light from her body.   And then she began to scream.    

As her aura intensified, something appeared around her like a bubble, which would vanish and reappear, and sometimes glow bright green.   There was a high-pitched whine as the energy intensified, but this was soon drowned out by Luffa's furious wail.  

Broly tried to attack Luffa in spite of this, but his blows were deflected away.    Soon, he gave up trying, and allowed whatever was happening to Luffa to take its course.  

"Impossible," 44 said as she watched what was happening.   "She can't be...  Not her too!"

At last, Luffa's body began to change, and grow.   The muscles on her arms and legs expanded, and even her height began to increase.    Her hair, which had been standing straight up and glowing yellow, now extended out a little further from her scalp, and the locks stiffened, resembling great claws of light reaching out for the darkened sky.   Her eyes were still covered by the tinted goggles she wore to protect her from the Blutz waves of the approaching comet, but beneath the lenses, her eyes glowed a brilliant white, which made her goggles glow from within.

And when it was all finished, she stood before Broly looking almost exactly like him.    She was not as big as he was, but she was much larger than her former self, and her hair and tail now had the same green-yellow color as his.    Her black shirt had stretched to contain her expanded torso, and her baggy yellow pants looked more like tights.

"Now then," Luffa said with a laugh.   "Was this what everyone was so worried about?"

"No way...." Laddis said with a gasp.    "She... she did the same transformation as Broly!"

"That's nuts!" Pells exclaimed.   "She didn't even know who he was until a minute ago!"

"She must have figured it out," Felds said.   "She studied his ki  and worked out how to do it herself, in just a few seconds."  

"That's nuts!" Pells exclaimed again.

Luffa now stood over two meters tall, her face twisted in a savage scowl to match Broly's.   But then she looked at the others and clicked her tongue.  

Luffa looked at them and laughed.   "You guys don't get it," she said.    "I didn't just now figure out how to do this!  I've known how to do this all along."

"What?" Felds screamed.  

"That's... nuts!" Pells exclaimed a third time.  

"What, like it's hard?!" Luffa shouted.   "Laddis was playing around with his Super Saiyan form, so what do you dopes think I was doing back in the day, huh?    I was afraid I'd lose control and blow myself apart!    Unlike you Time Patrollers, I couldn't just look up how Kakarot did everything.   Had to work it out for myself.   I used to flash back and forth a lot during that first month.  But once I got a handle on it, I started looking for ways to make it better.  It didn't take me long to figure out how to adjust the power.   How to make myself swell up like this.  This is just one of the variations I came up with.     The only trouble is, I just couldn't find any use for this form.  My wife always liked it.  Thought I looked cute this way.   And that's nice and all, but that's about all I ever got out of it."

"Y-you could do this the whole time...?" Laddis gasped.

"So could you, probably," Luffa said.   "If you worked at it.   But enough about you Laddis, let's talk about your boogeyman."   She turned to face Broly and grinned.    "So, Broly.   If this form makes you 'legendary', and I abandoned it, then what does that make me?"

"You think you can mock me?!" Broly roared.   "I'll tear you to pieces!"

"Fool," Luffa said.   "I just told you.   I ditched this form because it didn't do me any good.    What does that tell you about the form I normally use?  I know all your strengths, Broly.   And I know all your weaknesses.   But if you're too frightened to attack me..."

Broly screamed and drew back his hand for another punch.    This time, Luffa did not dodge, and his fist simply stopped when it hit her chin.   He couldn't even stop her from smiling.  

"It's great for defense, isn't it?" Luffa asked, speaking without moving her jaw.   "We could punch each other all day, and not feel a thing."

Without warning, she moved away from his fist and delivered a roundhouse kick to his abdomen, then followed up with an elbow strike on his nose.   Broly was confused but unhurt.    He was visibly frustrated to see anything else that could match his strength.  

Luffa then unloaded a series of green ki  blasts on Broly, flinging the energy like a pitcher lobbing curveballs.  Broly deflected these, and sent them flying off into all directions.   The blasts exploded in the horizon, briefly lighting up the night sky as they burst.  

"And you still have a ton of power to bring to bear," Luffa said.   "And the speed is fine too.   For a while there, I was really starting to think I was on to something with this form.  I guess you never figured out the problem with it."

Broly responded with ki  blasts of his own.   He threw much larger globules of green energy at Luffa,  who took the opportunity to dodge them.   They exploded over the horizon, and even the light from the comet was washed out with green.   A few of his attacks did connect, but she simply powered through them, and came at Broly without slowing down.    They locked hands as they met, and thus began a test of strength.   For a moment, Broly seemed to have an advantage from his greater size, but that proved to be fleeting.    Within moments, Broly and Luffa were even.   And then he began to be pushed back...

"See, you're just some big menace, from what I can tell," Luffa said between grunts and snarls.    "All you do... with that power... is push people around... and conquer planets.   I'm a mercenary... and I don't get paid by the hour.   It's not enough for me to win, Broly.   I wanted to find ways... to improve, so that I could win faster, and move on... to my next job.  So while you were pushing everyone else around... I was pushing myself to surpass this form.    Want to know how?"

Broly's only response was to scream, and to push back with all of his might, but he couldn't get Luffa to budge.    At last, Luffa pulled free of his grip and raised her arm over her head.   It began to glow with energy, and she swung it down against Broly's left arm.   Unlike their earlier attacks on one another, this one actually managed to damage him, and Broly cried out as his flesh was singed from the contact.  

"I remembered the lessons I learned from my mother!" Luffa shouted.   "She taught me how to fight smarter, not just harder!   Weaker Saiyans have to make every shot count!   Inflict maximum damage as efficiently as possible!   If it works for them, then why shouldn't that work for everyone?   But you, you expend energy even when you're standing still, like you've got nothing to lose!"

"This form carries heavy defense and power," Luffa said, "but it's crap on precision!   Offensively, your only good move is to barrel right through your opponent, just beat the snot out of them!  But not everyone will be kind enough to just stand still and let that happen!   So you have to sacrifice some of that heavy defensive power and risk taking some hits yourself!   Like I'm doing now!"

As she spoke, her body shrank down, not to its original size, but about halfway.   Her hair still had the green tint to it, but her irises were visible again on her eyes, and her speed and strength increased remarkably.   More importantly, Broly was being overwhelmed by her renewed assault.  

"I tried this variation for a while!" Luffa continued.   "It's got a lot going for it.    What you're using now, it's mostly defensive power.    You weather your enemies' blows, then overwhelm them  with brute strength and speed, but there's not much room for finesse when you're that bulky!   But this gives me a little of both!  I can hit you faster and more accurately, and after a while, I figured out that I can channel the ki  better too!   You're just spilling it out in every direction, but I'm using most of mine to attack!"

"I'll tear you apart!" Broly screamed.   "You're nothing, do you hear?!"   But for all his vitriol, Broly couldn't touch her.     "You see!" Luffa scolded him.   "I'm vulnerable now, but it doesn't matter because I'm hurting you too much for you to fight back!   That's the way it's done!   And once I figured that out, I realized I didn't need this green crap at all!  I could just stick to the 'normal' Super Saiyan power and push forward with that!"  

Now, she shrank down to her normal size and color, and Luffa moved even faster, pummeling Broly from every possible angle.   Occasionally, green energy would appear at the point of her strikes, as Broly's immense ki  continued to protect him, but that field was weakening, and Broly was quickly losing ground.  He swung his arms in vain, desperately trying to grab hold of Luffa and take back the initiative, but she was too nimble for him, her movements too sure.

"Eventually, I realized the original form was the best, Broly!  I learned a lot from the form you're using, and maybe it'll come in handy from time to time, but when it comes to fighting, this is the way to go, and what else would a Super Saiyan do with this kind of power, anyway?"

"No!" Broly screamed.   "Noooo!"

He finally managed to grab hold of Luffa's head, and he slammed her face-first into the ground, digging a trench through the forest.   When he decided he had gone far enough, he unloaded a barrage of ki  blasts, bombarding the ground with one attack after another.  

Not far away, the Crapkickers were simply too stunned to react.     The entire mission had been far more than they had bargained for.    And so, only 44 was left to recognize the danger they were in.  She moved away from the relative cover near the time machine, and ran towards Broly as fast as she could.    

"Stop it!" she shouted.    "You can't keep firing all that energy straight down!   You'll destroy the planet!"

Broly stopped, but only long enough to look around and laugh at her.    "And what will you do about it, child?   If you're in such a hurry to go to your grave, then so be it!"  

He stood up and lurched toward her, his feet making the same awful squeak that they made before.   44 stood her ground, though whether this was through courage or sheer terror, she could not say.    

Broly raised his fist high over 44's head, and with a sick grin, he brought it down upon her...

... only for his hand to pass harmlessly through thin air.    

"What?!" he growled.    

"She's off-limits, Broly," Luffa shouted.   He looked up and found her floating in the sky, holding 44 in her left arm.  

"Y-you're okay?" 44 asked.    

"Of course I am," Luffa said.   There were only a few scorch marks on her clothes, but nothing more.  

"But he had you pinned down, and he kept shooting all that ki  at you!" 44 said.

"Yeah, I had to stay put while he was doing that, so I could deflect all that energy away from the planet," Luffa said.   "How do you think we managed to avoid getting blown up?"

"I'll kill you!"  Broly screamed.     "I'll rip your limbs off one by one!"

"Yeah, fine," Luffa said, "but leave 44 out of it.   I promised the kid her hat would stay on, and I take that kind of thing seriously."

"I've had enough of your jokes, woman!" Broly snarled.  

"Fair enough," Luffa said.   "I guess I should wrap this up."

With a flash of golden light, she vanished, leaving 44 hovering in the air by herself.    At first, 44 began to fall, before she used her own power of flight to stop herself.    While Broly was watching this, Luffa had closed the distance between them, and drove her fist into his gut.    It staggered Broly, and he cried out in pain as he coughed up a glowing green fluid.  

Flecks of this ki  charged blood landed on Luffa's face.    As she watched Broly recover, she licked some of it off with her tongue, and smiled.    

"Yeah, that clinches it.  When I first saw you," Luffa said, "I had hoped that you had somehow mastered that big bulky form, that you had come up with some interesting twist on it, something that would give me a run for my money.   But no.   If I was right about you, you would have at least been able to block that punch just now.    It looks to me like you just lucked into this green power, and you never challenged yourself to try anything else.   A legend ought to be better than that, Broly."

He tried to hammer her down with forearm strikes, but she deflected them with her own arms and focused on his abdomen, raining down ferocious punches and kicks without pause.    If Broly had a strategy, it seemed to be one of waiting for his opponent to tired out.    It never happened.  

"I can see how you might have given Kakarot some trouble!" Luffa said.   "At his level, a bruiser like you would be almost unstoppable!   But I'm not Kakarot.   I'm Luffa, and I'm better!"

She actually let him grab her in his massive arms, but only long enough to scream and force his hands away.    Then she held up her hand and began charging her fingers with red ki  energy.  

"I'm better than Kakarot!" she said.   "Better than you, and I'm damn sure better than Laddis over there!"  

She aimed her hand at Broly, pretending to line up a ki  shot, but this was just a feint.   As Broly moved to block her, she spin kicked his right arm, just below the shoulder.  

"That's a nerve strike," Luffa explained.   "The way you are now, you never stood a chance of hitting an opponent the way I did just now.   But I can pick you apart like this, cripple you one limb at a time!   And where will your defenses be then?"

Broly's only response was to scream, and Luffa simply screamed back at him.  

"That's all you've got!" Luffa shrieked.   "Just a lot of size and power and noise!  Well it's useless!  You want to be a monster?  A true freak?   Hah!   I'll show you a monster!"

To his credit, Broly's resolve never wavered.    He stood and fought, and at times, he even managed to block some of Luffa's attacks, even though his right arm was practically paralyzed.   But within minutes, she had worn him down the point where he could no longer defend himself at all.   For a time, the skies echoed with his baleful screams of rage, but they soon faded as his voice faltered.   Soon after, the only sounds that carried were Luffa's raucous laughter, and her low, furious grunts as she continued to batter Broly senseless.    

Finally, mercifully, Broly lost the power to maintain his transformed state, and his body shrank to its normal size.   As his hair and eyes returned to their normal color, Luffa pulled her last punch, and used only enough power to knock the wind out of him.    Broly collapsed, utterly defeated, but still breathing.  

"Good fight," Luffa told him.  "Maybe this wasn't such a waste of time after all.   Hey!   Laddis!"

"Y-yes?" Laddis called back.   He had taken shelter behind a large rock, and was very anxious about becoming the focus of Luffa's attention.

"Any further business here?  This whole thing was your idea, after all.   Are you sure you don't want to spar with me?"

"No!" he cried out.    "Ah, I mean.    No, that's all right.   Thank you... ma'am."

"Then lets get you and your crew out of here," Luffa said.   She turned away from Broly and marched back to the time machine.    "I want to reset this mission, and I don't need any spectators.   If no one wants to participate, then I'll just go alone."

"You.... you want to do this again?" 44 asked as she fell in behind Luffa.

"Damn straight," Luffa replied.    

"But why?" 44 asked.  "You've already won your wager with Laddis.   You've got nothing more to prove.   Broly was no match for you."

"Kid, I don't care about any of that," Luffa said.   "I'm here to train, remember?  Broly's no legend, but he held out for a good long while.   He's one tough bastard, and I figure if I re-do that fight a few more times, I can beat him even faster.    After about a hundred times, I ought to see some real improvement."

"A hundred times?!" 44 gasped.  

"Let's go, Laddis!" Luffa shouted to the others.   "Quit dawdling!  It's not like any of you should be tired.   I'm the one who did all the work!"   Then she looked over to 44.    

"How about you, kid?" she asked.  

"Me?"

"I don't know much about cyborgs," Luffa said, "but you can probably get something out of a workout like this, right?   Don't worry, I'll wear Broly down to a manageable level before turning him loose on you."

"Ah... maybe on a different mission?" 44 said.   "Something a little less... intense?"

"Hah!   Maybe some other time," Luffa said.   "After I've finished this business with Demigra, that is..."

********

     [8 April, Age 850.   Toki Toki City.]  

"So, how did it go?"

44 kept her distance from most of the other Time Patrol staff.   She preferred to avoid distractions wherever possible, but there were a few Time Patrollers who had managed to break the ice with her.    Taino, a Majin with a fondness for the Ginyu Force, was one of these.    Taino carried out her duties in a Frieza soldier uniform, and she once told 44 that she had programmed her scouter device to lock onto her friends whenever they were heading for one of the restaurants in the city, just so she wouldn't have to eat alone.  

"Well," 44 said, "the chronoscopy calculations added a lot to my workload, but they didn't turn out to be too difficult.   I shouldn't be behind schedule for long--"

"That's not what I'm talking about," Taino said.   "I meant the mission with Luffa.   That's all everyone's been talking about for days!"

"I know," 44 said as she poked at her bisque.   "I've overheard a number of people discussing it."

"Well, you were there," Taino said.   She threw out her arms for effect.    "What was it like?   I wish I could have seen Laddis' face.   That loudmouth's had it coming for months!"

"Fortunately, no one was hurt," 44 began.   "And my hat stayed on, so I dropped my protest of Luffa's use of the restricted PQ missions."  

"Do you ever take that thing off?" Taino asked.    She pointed at the mesh-back cap and read the markings on the front.    "Ninety-eight CIAL?   What even is that?"

"It's a trucking company on Earth," 44 explained.   "I just like the way it looks."

She removed the cap, and released a pile of shoulder-length white hair that she had kept stuffed inside.    

"Why do you wear your hair long if you keep it under your hat all the time?" Taino asked.  

44 shrugged.   "I just do.   Anyway, the mission went well.    I don't want to try another one like that, though.    It's too intense for me."

"See, this is why you should join the Taino Force!" Taino said.     "We always do PQ's together, and we stick to the lower difficulty missions.   Plus, you can wear one of these cool uniforms!"

"Sorry," 44 said.   "I've never been much of a joiner."

"Oh, I get it," Taino said.   "You're waiting for Luffa to start her own team, so you can join up with her.   Well, I can't blame you.   She's definitely got the 'it' factor these days.  Her fashion sense could use some work, but people like the baggy pants look, I can't argue with that.    Yellow and black might look good on you.   Sure, I can see it.   I can't wear yellow because... well, my whole body is yellow so it'd just be too much, but you're kind of an amethyst color, so it'd suit you."

"Even if she started a team," 44 said, "I'm sure she'd want warriors, not a clerk like me."

"Don't be so sure," Taino said.   "The key to team building is diversification.    Luffa's already got raw power down by herself.   Maybe she'd want to include someone who's good at math.    Besides, the way everyone tells it, she seemed pretty impressed with you.   They said you stood up to Broly.   No many clerks can say that."  

44 shook her head and looked down at her soup.    While she tried to decide how to respond, Taino's scouter began to chirp.    

"Whoops, I got a call on this thing," Taino said.  "Yes, Ukatz.   Yes.   Yes.   No, I don't think so.  No, that was Iass' job.   Uh-huh.   Right.   Okay, meet me at the base in ten minutes.    Yes, I mean my apartment, but that is  our base, at least until they let us use the conference room again.  Okay.  Right.    You too.   Bye."  

Taino quickly excused herself, barely noticing 44 as she left.  

"You think she'd want someone like me?" 44 murmured to herself.

Pass the happy!💖 When you get this, reply with 5 things that make you happy and send this to the last 10 people in your notifications!

(Hello Fox give us the LOW DOWN on your JOY)

Yay thank you!  I have gotten this ask TWICE so I will have to come up with TEN THINGS that make me happy, which is fortunately not hard at all!

1) Cats.  Like CATS.  Have you SEEN cats?  There are smart cats and dumb cats and sweet cats and mean cats and cats that want to sit on the other side of the room and blink at you and cats that want to live down your cleavage and they’re all AMAZING.

2) Being aroace!  Like, props to all other orientations out there, you do great work, but that somehow in the great grab bag of life i reached in and accidentally pulled out The Best Orientation?  I mean, not only do I not want sex, but I don’t want any of the stuff that might making not wanting sex complicated?  It’s like being told that you never have to brush your teeth again, or do your taxes.  I LOVE YOU, ORIENTATION.

3) Moss. Its so hardworking; it creeps in and softens hard stone and compacted earth and all it asks in return is a little water and whatever dust no one else was using.  And IT’S SO PETTABLE.  We live on a planet that sees an unwanted patch that nothing else can grow on and says “here, let me put something fuzzy on that, and then some day, if you want, you can pat it”.  Amazing.

3A) Not a totally separate thing because it’s conceptually similar to moss, but LICHEN.  Because they’re not a single thing, but they are formed when an algae and a fungus combine.  But at the same time they’re highly identifiable, because over and over the same algae and the same fungus find each other and make the same lichen.  This  is our planet’s most incredible ongoing love story and it can be found in a teensy tuft of gray fringe on an oak branch.

4) Making really dumb mistakes in public.  I used to feel dumb when I did something stupid like push on a pull door, because what if someone laughed at me?  But at some point my brain realigned because... laughter’s amazing?  And if they go home and tell their family over the dinner table about the dumb thing they saw someone do today, and they all laugh, then isn’t that more amazing?  So now when I try to walk through a plate glass window or something, I look around and hope someone was watching, because HERE, THIS IS MY GIFT OF STUPID TO THE UNIVERSE.  Now when I’m dumb, I’m happy.

5) Knitting.  Specifically, writing knitting patterns, which turns on part of my brains that just sparks and whizzes and is the delightful messy collision of coding and fiber arts.  What happens if we stick a P3tog here?  I think I know, but maybe?  Maybe not?  Maybe it will make the hat I’m picturing, or maybe my coding is off and I’ll knit something that looks like a sea anemone!  Who knows?  NOT ME! (Of course the real answer is that i will just hate my life choices every time I hit the P3tog, because P3tog SUCKS, but I said the writing was happy not the knitting itself!)

'I've never seen or heard of attacks': scientists baffled by orcas harassing boats

Susan Smillie - September 13, 2020

Reports of orcas striking sailing boats in the Straits of Gibraltar have left sailors and scientists confused. Just what is causing such unusually aggressive behaviour?  

When nine killer whales surrounded the 46ft boat that Victoria Morris was crewing in Spain on the afternoon of 29 July, she was elated. The biology graduate taught sailing in New Zealand and is used to friendly orca encounters. But the atmosphere quickly changed when they started ramming the hull, spinning the boat 180 degrees, disabling the autohelm and engine. The 23-year-old watched broken bits of the rudder float off, leaving the four-person crew without steering, drifting into the Gibraltar Straits shipping lane between Cape Trafalgar and the small town of Barbate.

The pod rammed the boat for more than an hour, during which time the crew were too busy getting the sails in, readying the life raft and radioing a mayday – “Orca attack!” – to feel fear. The moment fear kicked in, Morris says, was when she went below deck to prepare a grab bag – the stuff you take when abandoning ship. “The noise was really scary. They were ramming the keel, there was this horrible echo, I thought they could capsize the boat. And this deafening noise as they communicated, whistling to each other. It was so loud that we had to shout.” It felt, she says, “totally orchestrated”.

The crew waited a tense hour and a half for rescue – perhaps understandably, the coastguard took time to comprehend (“You are saying you are under attack from orca?”). To say this is unusual is to massively understate it. By the time help arrived, the orcas were gone. The boat was towed to Barbate, where it was lifted to reveal the rudder missing its bottom third and outer layer, and teeth marks along the underside.

Rocío Espada works with the marine biology laboratory at the University of Seville and has observed this migratory population of orca in the Gibraltar Straits for years. She was astonished. “For killer whales to take out a piece of a fibreglass rudder is crazy,” she says. “I’ve seen these orcas grow from babies, I know their life stories, I’ve never seen or heard of attacks.”

Highly intelligent, social mammals, orcas are the largest of the dolphin family, and behave in a similar way. It is normal, she says, that orcas will follow close to the propeller. Even holding the rudder is not unheard of: “Sometimes they will bite the rudder, get dragged behind as a game.” But never with enough force to break it. This ramming, Espada says, indicates stress. The Straits is full of nets and long lines; perhaps a calf got caught.

But Morris’s was only one of several encounters between late July and August. Six days earlier, Alfonso Gomez-Jordana Martin, a 31-year-old from Alicante, was crewing a delivery boat near Barbate for the same company, Reliance Yacht Management. They were proceeding under engine when a pod of four orcas brought their 40ft Beneteau to a halt. He filmed them – it looks more like excitement and curiosity than aggression – but even this bumping damaged the rudder. And the force increased, he says, over 50 minutes. “Once we were stopped, they came in faster: 10-15 knots, from a distance of about 25m,” he remembers. “The impact tipped the boat sideways.”

The skipper’s report to the port authority said the force “nearly dislocated the helmsman’s shoulder and spun the whole yacht through 120 degrees”.

At 11.30pm the previous night, 22 July, Beverly Harris, a retired nurse from Derbyshire, and her partner, Kevin Large, were motor-sailing their 50ft boat, Kailani, just off Barbate at eight knots, when they came to a sudden standstill. It was flat calm, pitch black. They thought they’d hit a net. “I scrambled for a torch and was like, ‘Bloody hell, they’re orcas,’” says Harris. The couple checked their position and found the boat pointing the opposite way. They tried to correct several times, but the orcas kept spinning them back. “I had this weird sensation,” Harris says, “like they were trying to lift the boat.” It lasted about 20 minutes, but felt longer. “We thought, ‘We’ve sailed across the Atlantic, surely we’re not going to sink now!’” Their rudder was damaged but got them to La Línea. It was a long night. “Kevin said I should get some sleep. I said, ‘Are you joking? I’m having a gin and tonic,’” recalls Harris.

While enjoying her drink, Harris could have spared a thought for Nick Giles, having a sleepless night alone after an almost identical encounter off Barbate just two and a half hours earlier. He was motor-sailing, and playing music when he heard a sudden bang “like a sledgehammer”. The wheel was “turning with incredible force” as the vessel spun 180 degrees, dislodging the autohelm and steering cables. “The boat lifted up half a foot and I was pushed by a second whale from behind,” he says. While resetting the cables, the orca hit again, “nearly chopping off my fingers in the mechanism”. He was pushed around without steering for about 15 minutes before they left him.

Catastrophic encounters between whales and boats are not unknown – the best-known events all took place in the Pacific. In 1972 the Robertson family from Staffordshire were shipwrecked off the Galapagos Islands after an orca strike (their book, Survive the Savage Sea became a classic). The following year, also on the way to those islands, Maurice and Maralyn Bailey’s 31ft boat was holed by a sperm whale. In 1989 William and Simone Butler lost their boat as a huge pod of pilot whales rammed them. In these and all other known cases, the mammals ignored the humans who took to life rafts; it was the boats that attracted their ire. More usually in encounters, the whale is left dead or injured. The International Whaling Commission records these strikes – more collisions are occurring with private boats as technological advances increase performance speeds.

The encounters described around Barbate were certainly frightening for the crew, who understandably felt targeted, but it’s unlikely they were meant as aggressive attacks. At least two other boats had harmless encounters. On 20 July Martin Chambers, a yacht master for Allabroad Sailing Academy, was unconcerned when they were joined by a pod near Barbate. One individual “had hold of the rudder and stopped us moving the boat”, he says. “That’s the first time I’ve seen them do that.” It seems the encounters increased in intensity, but it’s also worth considering that different boat constructions can suffer different outcomes – rudders on some modern boats can be quite fragile.

“These are very strange events,” says Ezequiel Andréu Cazalla, a cetacean researcher who talked to Morris. “But I don’t think they’re attacks.” Orca specialists around the world are equally surprised, agreeing the behaviour is “highly unusual”, but are cautious, given that the accounts are not from trained researchers. Most agree that something is stressing the orcas. And when it comes to sources of stress, there are plenty to choose from.

“The lack of tuna has led these orca to the very edge with only 30 adults left”

The Gibraltar orcas are endangered – there are fewer than 50 individuals left, with a continuing decline projected – adults and juveniles are sustaining injuries, suffering food scarcity and pollution. Their calves rarely survive. The Gibraltar Straits is, Cazalla points out, “the worst place for orcas to live”. This narrow stretch of water is a major shipping route. And the presence of orcas attracts more marine traffic – highly profitable whale-watching. Theoretically, it is regulated, but some operators flout rules about speed and distance to chase the animals. Constant harassment by boats affects the orcas’ ability to hunt. Which brings us to the biggest stress of all: fishing.

The orcas return to this noisy, polluted stretch of water for one reason – to feed. They specialise in hunting bluefin tuna, also highly prized by humans. The near collapse of bluefin tuna between 2005 and 2010 “has led this orca population to the very edge, with about 30 adults left”, says Pauline Gauffier, who has studied them.

The Straits is an important migratory route for the tuna. It has been economically crucial to this region for thousands of years – the Romans produced coins in Cadiz depicting the once bountiful fish. Local fisheries still use an ancient technique – almadraba, a complex system of trap nets. Each spring, the bluefin arrive to spawn in the Med; many find their way into the nets instead. In July and August, as the tuna leave for the Atlantic, the fishermen switch to drop lines – baited with fish and lowered with rocks. These artisanal techniques are far less harmful than trawling, purse seining or driftnets – and than the reckless sport-fishing boats speeding at 10 knots, trailing long lines.

“They target the orca, because they think there must be tuna under the pods,” says Jörn Selling, a marine biologist for Firmm whale watching and research foundation with 17 years’ experience in the Straits. “They go right through the pods, their hooks cutting the dorsal fins”.

In the past, the orca chased the bluefin to exhaustion, but with fewer and smaller fish available, and the pressures from human activity, some have adapted. As a result, there now exists what biologists call “depradation” – a complex balance between the orca, tuna, and humans – and what the fishermen call “stealing”.

Since 1999, two of the Straits’ five pods have learned to take tuna from the drop lines, leaving the fishermen pulling up the tuna head alone. It’s infuriating for the fishermen, but for the orca, this is high risk. Several have sustained serious injuries. “We see marks caused by fishing lines,” says Selling. “We hear about young orca getting hooked.” There are two females with severed flippers – “Lucia”, Selling says “lost her baby together with her flipper, due to the interaction with tuna fishermen”. Gauffier points out that “there is little the fishermen can do to avoid line or hook injuries” when orca interact; and it’s not known what caused the injuries. But many conservationists suspect some fishermen retaliate violently.

“The fishermen hate the killer whales,” says Selling. The orca are protected, but “unobserved, the fishermen do what they want. They see them as competitors.”

Stories persist of fishermen stunning orca with electric prods, throwing lit petrol cans, cutting dorsal fins. Cazalla has seen two orca with recent injuries (Morris thinks there was an injured individual at her boat). “One has a significant scar – you can see white tissue so it’s deep.” This, he thinks, is unlikely to be from a propeller, which would cause multiple scars.

Selling points out that the orca interact with the almadraba as well as drop-line fishing, and talks of a male which worked out how to navigate the labyrinth of submarine nets to take tuna in Barbate years ago. This orca was later observed with serious injury to its dorsal fin. It hasn’t been seen since.

But the orca have endured harassment for decades. What explains the new behaviour? Was there reduced noise during the Covid lockdown? Selling says yes. “No big game fishing, no whale watching or sailing boats, no fast ferries, fewer merchant ships.” He’s intrigued by the idea that the orca had two months with reduced noise – “Something most of them probably never experienced before” – and considers the possibility they felt angry as the noise restarted (Gauffier thinks this unlikely, but notes that the Barbate pod still actively chases tuna, “for which they need a quieter environment”).

There is one very unscientific phrase I hear repeatedly from several researchers: “Pissed off”. Some speculate that the multitude of stresses these highly sentient cetaceans have endured – years of grieving lost calves, injuries, competition for fish, coupled with a pause and reintroduction of human activity, could have affected their behaviour. There is a great deal we don’t yet know about orca, which, like us, have evolved complex cultures and different languages around the world. A couple of years ago Ken Balcomb from the Center for Whale Research talked about endangered orca being dependent on scarce chinook salmon in the Pacific Northwest. “I’ve seen them look at boats hauling fish. I think they know that humans are somehow related to the scarcity of food. And I think they know that the scarcity of food is causing them physical distress, and also causing them to lose babies.”

Sounds like anthropomorphising? Lori Marino, neuroscientist and president of the Whale Sanctuary Project found in orca brains an astounding capacity for intelligence. “If we are talking about whether killer whales have the wherewithal and the cognitive capacity to intentionally strike out at someone, or to be angry, or to really know what they are doing, I would have to say the answer is yes. They are likely defending a territory or resources.”

Meanwhile, Nick Irving from Reliance is wondering if he should send clients’ boats out after the last three sustained damage: “Is it reckless?” Neither of us say it, but we’re both thinking he doesn’t want to be the mayor in Jaws – the obvious, if lazy stereotype that comes to mind. Word is starting to get out, frustrating Espada. Friends call, asking about the “attacks”, if it’s safe to swim. “Are you mad?” she asks. “Of course it’s safe!” As shark conservationists know all too well, it’s difficult to protect endangered animals with a bad image.

This tiny population’s presence is of huge importance, and if human activity is affecting their behaviour, human activity must be regulated. Gauffier has presented the Spanish Environment Agency with a conservation plan proposing that in the Barbate area, “activities producing underwater noise should be reduced to a minimum”. This is the very least that should happen. Each sailor I spoke to was concerned that their activities had stressed the orca. Victoria Morris, who has been searching for a specialist subject when she returns to study marine biology in autumn has found her topic. The Gibraltar orca has one more ally – which is good because these majestic, beleaguered mammals need all the help they can get.

A beginners guide for skiing/snowboarding

It totally just occured to me that with nothing else to do this winter, people are probably looking at skiing as a good way to get out, do something, and remember that other human life exists within this universe while not exposing yourself to the threat of plague. And that’s a great idea! Because skiing is fun as hell and vastly superior to snowboarding in every way.

But I also realize that most people don’t have parents that consider skiing a necessity of life, and therefor didn’t start skiing pretty much right after they got the hang of walking. So, for those of you who want to get into the sport, here’s some useful advice from someone that’s been skiing for... I think about seventeen years? I’m honestly not sure.

And unless specifically stated otherwise, yes all this advice applies to snowboarding as well. They’re pretty similar sports.

Under the cut because this is very long and I’m not doing that to your dashboard.

Step one: Gear

- The most expensive part is the skis and the boots. As in, buying one pair of good quality skis + boots will probably be $1000+. So if you’re buying gear, you’d better be absolutely certain that you’re going to get at least a decade of use out of it. So, complete beginner? Don’t buy. Rent. Same thing for children; kids just grow too fast, they’ll need new gear every season. I know most ski shops will let you rent gear for a full season though, so that makes things a lot easier (and cheaper).

- Skiiers, get the hang of the basics before you get poles. They’re basically for extra balance, help moving over flats, and navigating especially messy terrain. Get some confidence on just skis first. Feel free to buy your own poles though; poles are cheap and they don’t come with any sort of performance level. Literally the only difference is height, grab type and paint job. Sizing is easy, you just need to be able to grab the handles with your elbows at a ninety degree angle and the tips on the floor. Ask if you’re not sure. Everything else is just personal preference. 

- Snowboarders, get wrist guards. That’s non-optional. You’ll be landing on your hands a lot. Save yourself the fractured wrists. Skiers can get them too, but snowboarders are the ones that really need them.

- Helmets are mandatory. For everyone. You are never too good for a helmet. Olympic level skiers have died from bad wipeouts without a helmet. Put your fucking helmet on. And I don’t mean a bike helmet or a skating helmet, you need to get a proper ski helmet. This is not optional.

- Goggles are also a must, but this one isn’t controversial. Keeps the wind out of your eyes, and also helps you see the hill better. Different tints are better for different lighting, but don’t worry too much about it; I’ve never bothered with different lenses. Just get a light orange tint; it’s best for flat light, which is the hardest conditions to see in.

- Get ski socks. They’re not hard to find, just make sure you get a pair that are comfortably tight. Loose socks cause blisters. And normally socks will not do, the socks need to be long. The tops should be under your knees, but still a good way up your legs.

- For pants, you want something light and comfortable. Sweat pants or leggings are perfect. Honestly, pajama pants will work in a pinch too. Don’t wear jeans unless you really hate yourself.

Step two: Staying warm

- Waterproof outside and layers on the inside. That’s what it all boils down to, really.

- A good winter jacket is your main concern. If your hood can come off, take it off, it’ll just get in the way. Not one of those long jackets either, you want your legs free. Also, zip up your pockets before hitting the slope! Nobody likes finding snow in their pockets. Nobody.

- Snow pants. Again, freedom of movement is the goal, make sure you’re fine. Also snowpants with suspenders may not be the best idea; there’s nothing worse than being on the top of a mountain and having to unzip your jacket to pull up a suspender. Also the snowpants go on the outside of the boots, not the inside. Just to be clear.

- Gloves or mitts. Again, waterproof is a must. If your hands get cold easily, mitts are a better choice here; you can have your fingers wrapped around a heat pack all day, while with gloves all you get is toasty palms and frostbitten fingers.

- Neckwarmer! It’s damn windy on the hill, cover your face up. You’ll be glad for it.

- Cycling back to the layers thing, to explain in more detail. The bottom and top of your clothes stay the same. Bottom layer is a comfortable shirt, which will be horrifyingly sweaty by the end of the day. Top layer is your jacket, which is waterproof and windbreaking. Everything in between is optional. Some sort of fleece or sweater is a good idea. Don’t wear a hoodie though, the hood will just annoy you all day. If you’re way too warm, lose a layer. If there’s no more layers to lose, unzip the jacket a bit. Do not take the jacket off. Seriously. Don’t.

Step three: Safety on the hill

The Alpine Code is the agreed upon universal code of conduct for skiiers and snowboarders on a hill. This is the most important thing you need to know. Not just because you’ll be in trouble if you break it, but also because not following puts you and everyone around you in danger.

Always stay in control. You must be able to stop, or avoid other people or objects.

People ahead of you have the right-of-way. It is your responsibility to avoid them.

Do not stop where you obstruct a trail, or are not visible from above.

Before starting downhill or merging onto a trail, look uphill and yield to others.

If you are involved in or witness a collision/accident you must remain at the scene and identify yourself to the Ski Patrol.

Always use proper devices to help prevent runaway equipment.

Observe and obey all posted signs and warnings.

Keep off closed trails and obey area closures.

You must not use lifts or terrain if your ability is impaired through the use of alcohol or drugs.

You must have sufficient physical dexterity, ability, and knowledge to safely load, ride, and unload lifts. If in doubt, ask the lift attendant.

This exact text will be on the back of your lift ticket, and on signs around the hill. These are the rules. Follow them.

To clarify some points:

- Stopping on the hill is totally fine; just stay off to the side, and make sure people can see you. This is especially important for snowboarders, because your stopping means sitting down. Be very sure that people will spot you in time to move out of the way. And if you’re in a group, line up vertically. Don’t collectively block the hill.

- When they say it’s your responsibility to avoid people in front of you, they’re not fucking kidding. If you can’t stop in time, you have to fall. It’s better than a collision, trust me. I don’t care if someone accidentally swerves directly in front of you, if your momentum is going to hit a person or thing, you need to stop that momentum immediately. This goes double if you’re about to hit a tree or something; please, for the love of god, fall. A wipeout will hurt. Hitting the tree can kill you.

- When you get off a lift, move. Immediately. There’s probably people a few seconds behind you, and you need to be out of the way. Also, if there’s multiple ways to go when unloading from a lift, make sure you know which way everyone on the chair plans to unload. Don’t fall over each other.

- For witnessing an accident, you don’t have to hang around and call ski patrol any time someone has a wipeout. Just pay attention to the other people on the hill, especially if you see a bad wipeout. If someone has a group of three or more, keep going; they don’t need you. But if you see a person wiped out alone or with one person, and they look like they’re struggling to get up, stop and check in with them. Ask if they’re okay. If the downed person is actually hurt, offer to go get ski patrol for them, even if they’ve got an uninjured friend; it’s better to have a stranger going for help while their friend stays.

- If someone wipes out and loses skis and/or poles up the hill from where they end up, grab them and bring them down if you can. That’s not alpine code really, it’s just basic manners. It’s incredibly hard to walk up a hill in ski boots; they’ll be eternally grateful to you.

Step four: Difficulty

If you look at a map of a ski hill, you’ll see every run marked with a symbol. That tells you how difficult that run is, by the standards of that particular hill.

Green circles are the easiest runs; these are gentle slopes that usually have lots of room to turn. I say usually, because CAT tracks also become green runs - those are the roads that brought machinery up to clear trees and stuff when they were building the ski hill. They’re a little narrow sometimes, but always a very mild slope. All green runs are groomed every day, so don’t worry too much about terrain. Most hills will mark their very easiest run, so that’s the place to start if you’re brand new.

Blue square is intermediate. They’ll be steeper than greens, but they’re usually groomed daily. Being steeper means they’re at more risk of ice, so watch out. Don’t try a blue until you’ve got some experience and confidence; if you’re a skier, you should have been using poles for awhile before you hit a blue. Make sure you’re confident in stopping, and know how to slow down. If you’re still relying on the snowplow instead of a proper brake, you’re not ready for a blue.

Black diamond is the hardest. Some of them are groomers, but plenty aren’t; thats how you get moguls after all. Black diamond runs are for very skilled skiers with years of experience. If you’re on a black and not feeling confident, then take it slow and careful, and don’t be ashamed to give yourself a muttered pep talk all the way down, possibly interspaced by frightened owl noises.

Double black diamonds are a symbol of mans hubris. These are never groomed. These are steep, messy, and personally hate you. If you’re not 100% comfortable on moguls, don’t take a double black. Even I don’t do double blacks; it’s just not the kind of skiing I prefer. Basically if you’ve learned something new from this guide, you’re definitely not ready for a double black.

Please remember that while these are universal symbols and meanings, every hill has a different standard of difficult. For example, a river valley or a man made hill will call their runs green, blue and black, but for a mountain skier the whole place would be very tame greens. Different area have different standards. If you’re trying a new ski hill, always assume that they’ve got higher standards than you’re used to. It’s better to underestimate your skill and do a few easy runs to warm up than to overestimate and find yourself stuck on a run you’re not prepared for.

Step five: Getting up the hill

While chairlifts are the classic method, there’s actually a lot of different ways to get up a hill, and no telling what a particular place will use. So here’s a full list of lift types, how to use them, and where you’ll probably find them.

Magic Carpet

It’s a conveyer belt. It’s literally just a big conveyer belt. You stand on it, and it brings you up. Short, slow, simple. These are usually found in areas meant specifically for beginners, at the very bottom of the hill. If there’s nobody in front of you and you’ve got skis, you can kinda shuffle walk up to go a little faster. Just don’t fall.

Tow Rope

These are like magic carpets, but a little more annoying. Instead of hopping onto a conveyor belt, there’s a rope being turned in a circle. You grab on, it drags you up, and you let go at the top. Again, these are found in basic areas. If you’ve got poles, hold them both in one hand, hold the rope with the other.

T-bar

Like a tow rope, but it’s raised off the ground and has bars shaped like an upside down T attached. You grab one of them at the bottom, get half under your butt, then hold onto the middle as it drags you up. If you’ve got poles, take em off and hold them in one hand. Each T can hold two people, one on either side. For the love of god, don’t try to sit down. It can pull you up the hill, but you’ve gotta work to keep upright. If you try and sit, you’ll fall backwards. If you’re riding a T-bar alone, it helps to have one hand holding the middle bar, and the other hand balancing out the other side of the T. T-bar’s are usually found on the lower mountain in easy areas, but they’re not uncommon at the very top for access to the hardest areas.

Poma Lift

Exactly like a T-bar, but instead of the T shape it’s just a bar with a plastic disk at the bottom. Unlike a T-bar, Poma’s are a single person lift; you just straddle it so that the disk is on your butt, and off you go. Yes, this means the middle bar looks incredibly phallic. That’s part of the fun. These are only found at the very top of the mountain, for access to the hardest areas. Like the T-bar, poles are held in one hand.

Chairlift

Ah, the classic. Chairlifts are the most common lift, and they come in many variations. Singles might as well be extinct; I’ve never actually seen a one person chairlift. Doubles are uncommon, and usually tend to be older and rickety. These days most chairlifts are triples, quads or six packs, although I hear eight person chairs are a thing in the Alps. Chairlifts range the entire mountain; look at the map and make sure you know you’re going to an area you can ski. For skiers, remove the straps on your poles, and hold them normally until you get the loading spot; once you’re ready to sit down, hold them in one hand. Snowboarders, remove one foot from your binding before getting in line. All chairlifts have either a safety bar or a windshield. Lower it once everyone’s sititng down, then just sit back and enjoy the view. No matter how tempted you are to check your phone, don’t do it unless you absolutely have to, and be very careful. If you drop something, you’re fucked. Don’t be concerned if the lift stops, that’s perfectly normal; someone might’ve fallen at the top or bottom, or needed help loading/unloading. Once you get to the top, everyone in the chair should communicate which way their going (to avoid getting in each others way), then raise the bar as you approach the top. When you reach the platform, stand up and push forwards.

If you don’t get off the chairlift in time, or fall down, don’t panic. There’s lift operators for a reason, and they’ll hit the emergency stop if someone falls in the unload area. Likewise, if you don’t make it off the chair in time, you’ll trip a wire as you go around and trigger an emergency stop, so that the liftie can help you down. Don’t just jump the few feet down, because then the liftie gets mad and you and also many people are skeptical about your sanity. Which I know. Because reasons.

Gondola

Finally, the mighty gondola. These bad boys are the comfiest ride, but also the most work to get on/off, so you’ll only ride a gondola to get from the base to the upper mountain. Before getting in line, remove your poles, skis, and snowboards. Carry them through the line. When it’s your turn to load, give your skis/snowboard to the liftie, who will load them onto the outside of the gondola you’re riding in; poles go into the gondola with you. Don’t be slow about it, cause the gondola won’t stop. Then everyone load in, have a seat, and enjoy a nice ride up in comfort and privacy. Check your phone, take pictures, look at the map, have a snack... you’ve got time, and you’re in a nice little bubble, so you don’t have to worry about losing anything. When you’re at the top, unload, grab your gear, and walk out of the way to put your skis/snowboard back on.

Step six: Everything else

Now for all the little details that’ll make the whole thing a lot easier for you!

Bring your own food if you’re on a really tight budget; ski lodges are like airports or theme parks. You’re a captive audience; everything is horribly overpriced. But if you do want a hot meal, tbh it’s usually worth it; ski lodge food is expensive, but they at least have the decency to make it good. Try to time your meals to be before or after the typical lunch rush; the lodges get horribly crowded around noon. ...Well, do that when the pandemics over; these days avoid the lodge like the plague. Because it is the plague. Your vehicle is your locker; bring your own lunch, and eat there.

Always have a spare pair of gloves/mitts in your boot bag. If you lose one, or one gets ruined somehow, you’ll be thanking yourself.

You should always have some essentials in your jacket pockets when skiing. All your stuff might be in your locker, but mountains almost always have multiple lodges, so you don’t want to be needing something when it’s an hour of lifts and skiing away. The universal necessities is some money (i find a 20$ bill is best), your phone, and a map if you don’t know the hill very well. If you use them, then extra hair ties, and a tampon and/or pad are also a good idea. Even if it’s not shark week. Doesn’t hurt to be paranoid. A protein bar or some sort of snack is also good, or gum/hard candies if you want. Also, in this day and age, have a mask in your pocket.

Weed is a traditional favourite of skiers and snowboarders everywhere; blazing is a popular way to pass the time on a chairlift. Just be careful not to drop anything, and you probably shouldn’t blaze it while skiing/snowboarding if you don’t have the skill and experience to safely do it while blazed. ...Oh and if it’s not legal where you are, you should probably pick a more subtle location.

In your boot bag, locker, or vehicle, it’s a good idea to have at least one bottle of water, some ibuprofen, blister packs, bandaids, and some normal socks, especially if you’re skiing. Ski boots are very uncomfortable footwear. You don’t really notice it on the hill, but after. My god, when you’re taking your boots off at the end of the day, it’s the most amazing feeling in the world. Being able to put on normal socks and shoes again is like a religious experience. Trust me. Normal socks. It’s so good.

Know the symptoms of frostbite! If your fingers or toes are numb and painful, it’s time to take a break and thaw. If it keeps happening, try getting heat packs; they’re little packets with chemicals in them, and as soon as you open the plastic wrap it starts a reaction that produces heat. It’s not hot enough to burn, and it’ll last all day. Keeps the fingers nice and toasty. They’re a skiing staple, you’ll love it.

If the group splits up, make sure you know where and when to meet up again. Don’t count on being able to text each other, cell service is not a guarantee. And if a member of the group isnt there at the end of the day, check with ski patrol; they might have been injured and wound up in medical.

If for whatever reason you can’t get back down the mountain on your own, head the nearest lift that goes to the base, and talk to the liftie. You can always ride the lifts down if you need to. There’s no shame.

If you’re riding up a lift and pass a tree completely covered in bras, panties, and those shitty plastic bead necklaces, don’t worry. Every good ski mountain has an underwear tree somewhere. It’s a time honored tradition. Respect the underwear tree.

If you’re skiing several days in a row, then taking care of your gear is top priority. As soon as you’re back home or in your hotel room, everything comes out of the boot bag and gets set out to dry over a heat vent. Boots too. Make sure to close all the buckles on your boots or they’ll be a bitch and a half to do up later. That step is extra important if you’re not skiing the next day; never leave your boots unbuckled.

Skiing is a very intense sport, and a good day of skiing is a serious workout. Plan your après ski. Hot tubs are perfect if you’ve got access to one; if not, take the longest, hottest shower you can stand. You need it; not only will it wash all that sweat off, but also it’ll make your life a little easier tomorrow. If you can get out of bed the next morning without groaning in agony, you probably weren’t skiing hard enough.

Finally, before going to a ski hill with chairlifts, please watch these two videos. It’s a two part review gleefully mocking a suspense/horror movie about three people getting stuck on a chairlift when a ski hill closes. To this day when me and my sibling are on a chairlift together and it stops, one of us will immediately declare that we’ll be trapped for a whole weekend, and the wolves are hunting us. It’s an extremely stupid movie, and an extremely funny review mocking it. The wolves are coming. Those notorious ski hill wolf packs.

where can i read more about the devegetation of north africa? (reliable sources that you prefer)

Hey hi.

So just wanna be very clear that this is not really my “area of expertise.” (More focused on North American environmental history; most reading on North Africa limited to megafauna distribution range.) More like a fun side-interest that I revisit from time to time. And these resources are mostly just about the Sahel, specifically. Including the environmental history of the Holocene (past 10,000 years in the Sahel), and also the dynamic and drastic ecological change that took place between 1895-1960, during colonial and post-independence land management schemes. But some of the resources here also deal with the geography of the Sahara. (There is also an interesting history of the Sahara during the Holocene, when the desert was full of lakes and river courses. Up until the 1970s, there were still isolated populations of hippo and crocodile in remote Sahara lakes and oases.)

I’ll recommend some of the older “classics.” As usual, I’d try to recommend writing from local people who are explicitly willing to share their ecological knowledge. But a lot of my recommendations are unfortunately from academics. And I’m sorry for that.

Assuming you’re referencing this:

When searching online for environmental histories or local environmental knowledge case studies of the Sahel, I see a lot of stuff sponsored by NGOs, the UN, and US academia, which will emphasize “rediscovery” or “utility” of “using” traditional knowledge for “combating climate change,” and many mentions of the “green wall” proposals. I’ll also see “white savior complex” kind of stuff, which talks about “crises” and “civil wars” as if they’re “endemic” to the Sahel. But (just my opinion), I don’t like those resources. They engage in cultural appropriation (”acquiring” local Indigenous knowledge), superficial posturing (Euro-American academics using cute language about “local knowledge” without holistically contextualizing the devegetation), weird culturally-insensitive elitist chauvinism (continuously talking about “religious conflicts” and “civil wars” in North Africa and the “urgency” to use “agriculture” to establish stable economics and therefore “law and order”), and reductionism (talking about importance of halting southward desertification and expansion of the Sahara, without acknowledging role of World Bank, IMF, etc. in continuing to use lending/debt to hold West Africa hostage.) Part of my skepticism of these sources is because I’ve met and/or worked with agricultural specialists from institutions in the Sahel and environmental historians who had worked for many years in the region. (They’ve shared some really cool anecdotal stories about the sophistication of dryland gardening in the Sahel, and how local horticulturalists would laugh at the Euro-American corporate agricultural agents and USDA staff sent in with their special “space-age chemically-coated super-moisture-retaining” seed supplies after independence.)

Fair warning: Most of my recommendations are a little old, from the 1970s and 1980s. Two of the main drawbacks of these “outdated” sources: since their publication, scholars have since greatly expanded lit/research about both imperialism and traditional ecological knowledge. (West Africa had only been “independent” for a short period of time, and the hidden machinations of neocolonial institutions weren’t as clearly visible as they are to us, today, I’d imagine. And some academics, writing about the Sahel in the 1980s, weren’t as willingly to openly call-out major institutions.) But I think they provide a brief background for Sahel’s ecology and agroforestry/horticulture.

So both of these are available free, online, through the New Zealand Digital Library. (Don’t wanna link them here, but you can find them online pretty easily.)

Firstly, from 1983/1984, there is this summary of desertification, traditional environmental knowledge, traditional land use systems, and agroforestry in the Sahel: National Research Council. 1983. Agroforestry in the West African Sahel. Washington, DC: The National Academies Press.

Something that was always exciting for me ...

Despite how dry and hot the Sahel is, fruit trees and gardens are actually very fertile and productive, for many reasons, mostly related to sophistication of local ecological knowledge of nutrient-replenishing relationships between different plants. An excerpt:

“Today, a number of agro-silvicultural systems appear to be practiced in the Sahel. Gardens are found within settlements where water is available, usually with a tree component that provides shade and shelter and, often, edible fruits or leaves. The same holds true for intensively managed, irrigated, and fertilized gardens near urban centers. Both subsistence home gardens and cash-generating market gardens are highly productive. Fruit and pod-bearing trees, shade trees, and hedges or living fences are the "forestry" components, sometimes supplemented by decorative woody plants. Mangoes, citrus trees, guavas, Zizyphus mauritiana (Indian jujube), cashews, palms, Ficus spp., and wild custard-apples are prominent kinds of fruit trees. Shade is often provided by Azadirachta indica or similar species, while fencing is provided by thorny species of Acacia and Prosopis, and by Commiphora africana, Euphorbia balsamifera, flowery shrubs such as Caesalpinia pulcherrima (paradise-flower), and other species.

Close to the settlements is a ring of suburban gardens, often irrigated, in which cassava, yams, maize, millet, sorghum, rice, groundnuts, and various vegetables are grown, for subsistence as well as sale, depending on the ecozone.”

Then this sounds more like what you might be looking for? Basically, a history of environmental knowledge and the ecological trends of the past 10,000 years in the Sahel.

National Research Council. 1983. Environmental Change in the West African Sahel. Washington, DC: The National Academies Press.

Though this report from 1983 is now kinda outdated, and has some iffy elitist and vaguely-chauvinist language at times, but it is still accessible, generally easy to read, concise, and  it goes out of its way to say that 1970s drought and current environmental crises in the Sahel cannot be understood without addressing the early Holocene ecology of the Sahara/Sahel.

So the report emphasizes the importance of context, by addressing the drying of river courses and lakes in the Sahara of the Late Pleistocene, the early domestication of crops, the emergence of cattle and goat over-grazing, the importance of gum arabic and acacia trees in maintaining moisture in gardens, early trans-Sahara caravan travel, medievel geographical knowledge of the Sahara, etc.

“Because climatic change and variability are regular features of the Sahel, the native plant and animal communities of the region are generally well adapted to the range of climatic variation existing in the region. [...] Many efforts in "development" or modernization have also contributed to their plight. [...] In order to provide a better understanding of the role of human activity in modifying Sahelian ecosystems, this chapter briefly explores nine agents of anthropogenic change: bush fires, transSaharan trade, site preferences for settlements, gum arabic trade, agricultural expansion, proliferation of cattle, introduction of advanced firearms, development of modern transportation networks, and urbanization. These agents illustrate the breadth and diversity of the human impact on the region.”

----

Then there is this: Jeffrey A. Gritzner. The West African Sahel - Human Agency and Environmental Change. 1989.

And I also recommend the work of Jeffrey A. Gritzner. He’s American, but respectful and knows what he’s talking about. Gritzner works with dryland ecology; human ecology, especially relationships with plants/vegetation; environmental change during the Holocene (past 10 to 12,000 years); and traditional environmental knowledge. And he’s especially knowledgeable about the Sahel, North Africa, and Persia/the Middle East, where he worked with region-specific horticulture in the 1970s in Chad, Senegal, etc. during the peak of the drought, and had personal observations of post-independence neocolonial mismanagement and continued corporate monoculture from World Bank, IMF, etc. His writing contrasts local/traditional gardening/plant knowledge with imported corporate/neocolonial agriculture.

---

Beginning in about the 1990s, it seems to me that Euro-American geography/anthropology departments were much more willing to use words like “empire” and “neocolonialism” and more willing to call-out corporate bodies and institutions, so there are many better articles from after that period.

Again, these resources are mostly just about the Sahel.

Then, since the early 1990s, for better or more specific case studies of local-scale environmental knowledge, I think it might be easier or more fruitful to search based on subregion or specific plants. My perception is that, though much of the woodland and savanna ecology might be similar across the region, the Sahel is still spatially/geographically vast, stretching from the Atlantic Ocean to the Red Sea. And so, there are so many different diverse communities of people, with long histories situated in place, and there are diverse local variations in approach to horticulture. So, if you’re more interested in traditional ecological knowledge and local food cultivation, it might be easier to pick a specific subregion of the Sahel, or to pick a favorite staple food, and then to search those keywords via a university library website, g00gle scholar, etc.

(About the distribution range and local extinction, in the Sahel, Sahara, and Mediterranean coast, of lion, cheetah, elephant, giraffe, rhino, desert hippos, the “sacred crocodile,” etc. More my cup of tea. I’ve got some maps and articles, I’ll try to put them into a list of resources, too.)

Experts watch in horror as 2 dead satellites are on track for a potential collision

Experts watch in horror as 2 dead satellites are on track for a potential collision

For the second time this year, experts can only watch and wait as two large objects close in on a potential collision course in low-Earth orbit.

According to space debris tracking service LeoLabs, an old, discarded Chinese rocket stage and a defunct Russian military satellite are due to pass within 12 metres (40 feet) of each other on 16 October 2020 at 00:56 UTC.

There is, LeoLabs says, a greater than 10 percent chance that the two objects will collide at an altitude of 991 kilometres (616 miles) over the Weddell Sea just off the Antarctic Peninsula.

We are monitoring a very high risk conjunction between two large defunct objects in LEO. Multiple data points show miss distance <25m and Pc between 1% and 20%. Combined mass of both objects is ~2,800kg.

Object 1: 19826 Object 2: 36123 TCA: Oct 16 00:56UTC Event altitude: 991km pic.twitter.com/6yWDx7bziw

— LeoLabs, Inc. (@LeoLabs_Space) October 13, 2020

“This is probably one of the potentially worst accidental collisions that we’ve seen for a while,” space archaeologist Alice Gorman of Flinders University in Australia told ScienceAlert.

The two objects are substantial, with a combined mass of about 2,800 kilograms (6,170 pounds), travelling in opposite directions with a relative velocity of 14.7 kilometres per second  (9.1 miles per second). The rocket stage is part of a Long March 4B rocket launched on 10 May 1999; after it safely transported its payload, the stage was discarded, as has been normal procedure for decades.

The satellite is a Russian Parus military satellite weighing about 825 kilograms (1,820 pounds), launched on 22 February 1989, and previously used for communication and navigation. It’s no longer operational. So neither object can be communicated with or manoeuvred to avoid a smash-up.

1/ This event continues to be very high risk and will likely stay this way through the time of closest approach. Our system generates new conjunction reports 6-8x per day on this event with new observation data each time. pic.twitter.com/d3tRbcV2P0

— LeoLabs, Inc. (@LeoLabs_Space) October 14, 2020

It’s similar to a situation earlier in the year, in which two old satellites were projected to pass within 15 to 30 metres of each other, with a one in 100 chance of collision. They later sailed harmlessly by each other like ships in the night.

In that close approach, as well as this, the chance of collision is complicated by the shape of the spacecraft. The Parus satellite has a 17-metre (56-foot) boom that could easily close the projected gap between them. But the worst case scenario would be if the two bodies collide.

There’s no risk to us here on Earth, even if the potential collision would be taking place over a densely populated region. The concern is that the two objects would create a shower of small debris. This would burn up on atmospheric entry – but it’s more likely to hang around in low-Earth orbit creating hazards for other objects up there.

“Last year, when India performed an anti-satellite test, that created about 400 cases of trackable debris. So we’d be looking at at least that number. And then of course, there’s all the small bits which aren’t trackable,” Gorman said.

“We’re not yet in a position where we can actively remove any debris like this. So it’ll be up there for a while. And because of the altitude of about 1,000 kilometres, this stuff isn’t going to reenter within a matter of weeks or months. Some of it is likely to be up there for quite some time.”

While the rate of collisions is currently quite small – in the last 10 years, they constituted just 0.83 percent of all fragmentation events in low-Earth orbit – the concern is that more serious collisions will take us rapidly down the path to Kessler Syndrome.

This was predicted by former NASA astrophysicist Donald Kessler in 1978, and it states that, with enough junk and debris in space, eventually there will be a runaway collision cascade. One collision will create hundreds or thousands of pieces of junk that will go on to collide with others, until near-Earth space is basically unusable.

“We’re not yet at that Kessler Syndrome point. But how much closer in time does this bring us to that point?” Gorman said.

“We’ll have a sudden injection of a large amount of debris that was unpredicted. And this means there’s a likelihood of other things colliding with those pieces of debris. It just makes the situation a bit more complicated.”

2/ Current risk metrics from our most recent CDMs: Miss distance: 12 meters (+18/-12 meters) Probability of Collision: >10%, scaled to account for large object sizes Relative velocity: 14.7 km/s pic.twitter.com/y44QXyhHJK

— LeoLabs, Inc. (@LeoLabs_Space) October 14, 2020

This, of course, is the worst case scenario; according to LeoLabs’ probability calculations it’s not likely here. But even if the two objects miss each other, it’s only a matter of time before something big does collide in near-Earth space, and we don’t currently have the ability to stop it.

This event is a grim reminder that the space debris problem, if left to its own devices, is only going to get worse. The good news is that space agencies are working towards solutions. By far the biggest generator of space debris is explosions in orbit caused by leftover fuel and batteries; space agencies and aerospace engineering companies are starting to incorporate end-of-mission planning such as defuelling in orbit to minimise those risks.

And new technologies, such as automated collision avoidance manoeuvring and space junk collection, are in the works. So we just have to hope we can continue to avoid large collisions until we have some better space junk mitigation techniques. 

“My feeling about this is probably it’s not going to happen, just to be optimistic. But we’ll have to wait,” Gorman told ScienceAlert. “Let’s keep our fingers crossed.”

LeoLabs is continuing to monitor the situation. You can follow its reports on Twitter.

EXPERIMENT LOG: Using simulators to examine meta-universal differences in standard particle physics, tests 12A-D.

Project Summary: First run of tests to simulate and compare collisions from different universes. This was honestly more of a calibration run to test whether I was doing the right thing with the right settings, so on. Inconclusive results.

VIEW PROJECT?

START LOG

Corresponding personal log: 24 August 2020

Personal Notes: I’ve been working on this since April. It’s a little disheartening to know I can’t even check my own results - I don’t have access to a collider in my universe to double-check what I’m doing, so I’m piloting blindfolded. And because this isn’t my universe, it’s been obstacle after obstacle. I’ve had to do workaround after workaround to get this working on my personal computer - turns out Windows don’t like to run Linux programs! - and I had to TEACH myself C++, then do more workarounds because my command terminal kept throwing a fit. I hope - I really really hope - that this is just a steep learning curve.

Methods: So there’s really only one simulator I can use, because it’s the only one that would run on my personal computer. Took me a week to get the bloody thing set up. Turns out Windows doesn’t like running Linux programs.

But anyway, it should allow me to simulate colliders as well as play with some of the physics laws, once I’m good enough with programming it. It’s already taken me months to properly learn how to program it in the first place, because it’s written in C++, not FORTRAN like I’m used to. (I don’t know if that’s a universe difference or not, because the website lists the iteration before this one as being written with FORTRAN. Despite the difference being years, it could be an update I missed.)

Experiment consists of four runs total.

Run 1: Attempted simulation of my own collider.

Run 2: Collision experiment carried out at Brookhaven’s RHIC.

Run 3: Simulation of the above collision experiment (for comparison).

Run 4: Simulation of my collider, with an attempted adjustment to account for speed of light differences.

Run 5: Simulation of above collision experiment, with an attempt adjustment to account for speed of light differences.

Results: Inconclusive. Honestly, I was expecting them to look far less similar, but I guess that was optimistic thinking. They’re all similar runs - as similar as I can make them, minus the simulation of mine.

I’m going to focus on photon energy right now - I’ll get to analyzing the others later. If the speed of light is different, I’m curious about the differences in light that exist here, so yeah. I’m focusing on photons, since they’re basically light.

Analysis: Honestly, every run looks almost identical. Ugh.

As far as similarity, I expected the real experiment and its simulation to be the closest, because they’re literally the same experiment, one run on a computer and the other run in real life, but no, they aren’t. Either that means there’s more wobble room in this universe than I thought, or I’ve set something wrong on my simulation. They’re dissimilar enough to make me suspicious.

What I find really interesting is that the two closest to each other are the real experiment and the lightspeed-adjusted simulation. That doesn’t completely make sense, because PYTHIA has the numerical speed of light built into it, but... Interesting. This also indicates I may have something wrong with my simulation, because light-adjusted stuff shouldn’t be particularly similar to anything real right now, so I’ll need to keep an eye on that.

Outside of that, I don’t know what that means. I may need to get another beam time request in to compare to.

Least-similar was the simulation of my own collider and run 5, one of the lightspeed-adjusted experiments. At least THAT makes sense - simulated versions of my own collider and a wrong-lightspeed alternate universe collider SHOULD be pretty different.

The rest of it is really inconclusive. Hopefully analyzing more data will yield better results.

MASSIVE DISK GALAXIES FORMED EXCEPTIONALLY EARLY IN COSMIC HISTORY ** Synopsis: In our 13.8 billion-year-old universe, most disk galaxies like our Milky Way were thought to form gradually, reaching their large mass relatively late. But now astronomers led by Marcel Neeleman from the Max Planck Institute for Astronomy, using the ALMA observatory, have found a massive rotating disk galaxy, seen when the universe was only ten percent of its current age. The observation shows that some disk galaxies must have formed much more quickly. This supports earlier computer simulations that had indicated the role of a quick, “cold” mode of galaxy formation. The results have been published in the journal Nature. ** At the time of the big bang, the universe was featureless and uniform -- a bland plasma of charged particles. Explaining how, over the following 13.8 billion years, a rich array of structures formed in our cosmos, including a diverse variety of galaxies with countless stars, is one of the fundamental questions of modern cosmology. Now, a discovery made by a group led by Marcel Neeleman (Max Planck Institute for Astronomy) has uncovered an important piece of the puzzle: The astronomers detected a disk galaxy -- similar to our home galaxy -- that had reached a considerable mass of 70 billion solar masses as early as 1.5 billion years after the big bang, when the universe was 10% its current age. The result provides valuable input for a present-day discussion about how galaxies form, which had considered two fundamentally different mechanisms: a “hot mode” scenario, where hot gas needs to cool down for a long time to form a disk, and the more recent “cold mode accretion” scenario, where cool gas is led onto a newly formed galaxy in a way that creates a disk on shorter time-scales. Finding a fully-fledged, massive disk a mere 1.5 billion years after the big bang indicates that cold mode accretion must play a significant role in galaxy formation -- which is indeed what computer simulations like the Auriga and TNG50 simulations had indicated. From Cosmic Uniformity to Diversity According to modern cosmology, the universe as we know it began in a hot dense phase 13.8 billion years ago, as an almost perfectly homogeneous plasma made of electrons and protons. Even after that plasma had cooled down sufficiently for atoms to form, it had almost the same density everywhere. One of the central tasks of astrophysics is to explain how we have gotten from this nearly featureless universe to the cosmos we see around us today, with its galaxies, stars, and planets. Going by the best available simulations, the “backbone” of cosmic structure is a cosmic network of so-called dark matter, which does not interact with light at all, and thus remains invisible. Under their own gravity, minute inhomogeneities in the density of dark matter grow over billions of years -- where there is a little bit more dark matter, gravitational attraction is a little bit stronger, so additional dark matter is pulled in. The result is a gigantic cosmic network of filaments and nodes (with greater density) surrounding cosmic voids (with smaller density). By mass, dark matter accounts for roughly 85% of all matter in the universe, while atoms like the ones our stars, our planets and our bodies are made of account for only 15%. By mass, the dark matter network is by far the most important large-scale structure in our universe. But as human beings, we are particularly interested in the stuff we ourselves, and our environment, are made of -- and for astronomers, that ordinary matter is what can be observed using telescopes and astronomical instruments. Forming Galaxies and Stars Galaxies form within clumps of the cosmic dark matter network, so-called halos, which have a markedly higher density than the surrounding matter. It is natural that these dark matter concentrations gravitationally attract ordinary matter, but for that ordinary matter to form luminous stars, and thus to become visible over large distances, certain conditions need to be met. Stars form when smaller regions within a cloud of molecular gas collapse, and heat up. But in order for that to happen, and for gas to form molecules in the first place, the gas needs to be sufficiently cool -- directly before star formation, a mere 10 degrees Celsius above absolute zero, or 10 Kelvin. Under those conditions, it is quite a challenge to build large galaxies like our own Milky Way, which have a massive disk of cool gas, in which new stars are forming. An important mode of galaxy growth are collisions and mergers of smaller galaxies. “Most galaxies that we find early in the universe look like train wrecks because they underwent consistent and often ‘violent’ merging” says Neeleman. “These hot mergers make it difficult to form well-ordered, cold rotating disks like we observe in our present universe.” Wherever gas falling onto such galaxies is heated up, which happens inevitably when gas clouds collide and form so-called shock fronts, it takes a few billion years of cooling-down before an orderly gas disk can form. A Cool Alternative Way of Forming Large Disk Galaxies Modern simulations of structure formation make use of supercomputers to follow dark matter and gas over billions of years after the big bang. In effect, they create a virtual universe, based on the known physical laws, that allows scientists to analyze all phases of cosmic evolution. Two recent simulations, the smaller-scale Auriga simulation of Milky-Way-like galaxies and the large-scale detailed TNG50 simulation, opened up the possibility of an alternative mode of formation: Already cold gas flowing into galaxies, following the filaments of the dark matter network, avoiding the collisions that would heat the gas up, allows for the formation of massive disk galaxies at much earlier times than the collision-and-cooling scenario. How to Find Those Early, Cool Galaxies? At this point, it was clear that the most direct way of testing the prediction from the simulations would be to find massive galactic disks in the early universe. After all, that is what the hot-then-cooling-down scenario could not explain, while the cold flow scenario could. Fortunately, astronomers are in a position to observe the distant past. Light from distant regions takes some time to reach us. If a distant region is so far away that its light takes 12 billion years to reach us, light from that distant region reaching our telescopes today carries information about how that region looked 12 billion years ago, when the universe was about 10% of its present age. This was the motivation for Marcel Neeleman and his colleagues to set out in search for early disk galaxies. The problem is that distant galaxies are difficult to observe. Not only do you need a powerful telescope, you also need to know where to look. Neeleman’s collaborator and former PhD co-advisor J. Xavier Prochaska is an expert on using extremely bright, extremely distant quasars -- whose luminosity is powered by matter falling onto a galaxy’s central black hole -- to deduce the presence and properties of gas that is between the distant quasar and us from the way that this gas absorbs some of the quasar’s light. ALMA Finds the Wolfe Disk Neeleman and his colleagues used observations with the ALMA observatory, an array of dozens of radio telescopes in Chile, to identify 6 early galaxy candidates in this way, which were so distant that their light had travelled on the order of 10 billion years to reach us. When they used ALMA’s unrivalled sensitivity and resolution to observe the brightest of those candidate objects, DLA0817g, in more detail, they found tell-tale wavelength shifts, known as Doppler shifts, that told them they were indeed dealing with a large, stable, rotating disk. Additional observations were made with the VLA radio telescopes. Combining the apparent size with the data quantifying disk rotation, the researchers concluded they were looking at a disk with the mass of 70 billion Suns. The observations show the disk as it was when the universe was a mere 1.5 billion years old, about 10% of its current age. The researchers named DLA0817g the “Wolfe Disk,” after the late Arthur M. Wolfe, former PhD advisor to three of the paper’s four authors, including Prochaska and Neeleman. Wolfe’s long-term research program on the absorption of quasar light is what made this and many other discoveries possible. The Wolfe Disk’s mass and age are a strong indication that the cold mode accretion scenario has indeed played a significant role in cosmic evolution -- vindicating simulations like Auriga and TNG50. The details will still need additional input from both simulations and observation. “We think the Wolfe Disk has grown primarily through the steady accretion of cold gas,” says Prochaska, “Still, one of the questions that remains is how to assemble such a large gas mass while maintaining a relatively stable, rotating disk.” Wolfe Disks Are Probably Quite Common Out There A galaxy will only be detectable by its absorption of quasar light if there is a chance alignment between us as the observers, the galaxy, and the quasar. Such alignments are rare in and of themselves; if the Wolfe Disk were itself an unusual, uncommon object, that would increase the improbability of this chance discovery considerably. Much more probable is the assumption that galaxies like the Wolfe Disk are comparatively common in the early universe. “The fact that we found the Wolfe Disk using this method, tells us that it belongs to the normal population of galaxies present at early times,” said Neeleman. “When our newest observations with ALMA surprisingly showed that it is rotating, we realized that early rotating disk galaxies are not as rare as we thought, and that there should be a lot more of them out there.” That, too, is a claim that the astronomers hope to test by continuing their search, and detecting additional massive disk galaxies in the early universe.

Dark Matter 101: Looking for the missing mass

Here’s the deal — here at NASA we share all kinds of amazing images of planets, stars, galaxies, astronauts, other humans, and such, but those photos can only capture part of what’s out there. Every image only shows ordinary matter (scientists sometimes call it baryonic matter), which is stuff made from protons, neutrons and electrons. The problem astronomers have is that most of the matter in the universe is not ordinary matter – it’s a mysterious substance called dark matter.  

What is dark matter? We don’t really know. That’s not to say we don’t know anything about it – we can see its effects on ordinary matter. We’ve been getting clues about what it is and what it is not for decades. However, it’s hard to pinpoint its exact nature when it doesn’t emit light our telescopes can see. 

Misbehaving galaxies

The first hint that we might be missing something came in the 1930s when astronomers noticed that the visible matter in some clusters of galaxies wasn’t enough to hold the cluster together. The galaxies were moving so fast that they should have gone zinging out of the cluster before too long (astronomically speaking), leaving no cluster behind.

It turns out, there’s a similar problem with individual galaxies. In the 1960s and 70s, astronomers mapped out how fast the stars in a galaxy were moving relative to its center. The outer parts of every single spiral galaxy the scientists looked at were traveling so fast that they should have been flying apart.

Something was missing – a lot of it! In order to explain how galaxies moved in clusters and stars moved in individual galaxies, they needed more matter than scientists could see. And not just a little more matter. A lot . . . a lot, a lot. Astronomers call this missing mass “dark matter” — “dark” because we don’t know what it is. There would need to be five times as much dark matter as ordinary matter to solve the problem.  

Holding things together

Dark matter keeps galaxies and galaxy clusters from coming apart at the seams, which means dark matter experiences gravity the same way we do.

In addition to holding things together, it distorts space like any other mass. Sometimes we see distant galaxies whose light has been bent around massive objects on its way to us. This makes the galaxies appear stretched out or contorted. These distortions provide another measurement of dark matter.

Undiscovered particles?

There have been a number of theories over the past several decades about what dark matter could be; for example, could dark matter be black holes and neutron stars – dead stars that aren’t shining anymore? However, most of the theories have been disproven. Currently, a leading class of candidates involves an as-yet-undiscovered type of elementary particle called WIMPs, or Weakly Interacting Massive Particles.

Theorists have envisioned a range of WIMP types and what happens when they collide with each other. Two possibilities are that the WIMPS could mutually annihilate, or they could produce an intermediate, quickly decaying particle. In both cases, the collision would end with the production of gamma rays — the most energetic form of light — within the detection range of our Fermi Gamma-ray Space Telescope.

Tantalizing evidence close to home

A few years ago, researchers took a look at Fermi data from near the center of our galaxy and subtracted out the gamma rays produced by known sources. There was a left-over gamma-ray signal, which could be consistent with some forms of dark matter.

While it was an exciting finding, the case is not yet closed because lots of things at the center of the galaxy make gamma rays. It’s going to take multiple sightings using other experiments and looking at other astronomical objects to know for sure if this excess is from dark matter.

In the meantime, Fermi will continue the search, as it has over its 10 years in space. Learn more about Fermi and how we’ve been celebrating its first decade in space.
