EXCLUSIVE: Cobalt-60 dirty bombs combined with mRNA vaccine suppression of chromosomal repair mechanism could unleash CANCER DEATH WAVE across America and vaccine-compliant nations

(Natural News) In today’s exclusive analysis, we detail how cobalt-60 dirty bombs unleash a low level of radioactive contamination in the affected area. This radiation is not intense enough to kill people from simple radiation exposure, but when combined with the mRNA “vaccines” and their spike protein suppression of the NHEJ chromosomal repair mechanism in cell nuclei, even a low level of…

hey guys, this is a post about side order and what we can somewhat gather about it so far. this'll be a long one, so hang tight. i've seen others vaguely talk about these ideas, so i decided to go all-out.

this image is of what i'm going to refer to as the 'landscape of thorns,' which is a 'long-term nuclear waste warning message.' these being used to sway humanity from intruding on highly dangerous sites.

as certain kinds of radiation can stay toxic for thousands of years, a warning of the dangers of this plant were needed. non-linguistic messages were attempted at first by a report from the sandia national laboratories, one of the three development and research laboratories of the department of energy's national nuclear security administration. {DOE, NNSA} the aim of this series of messages were to warn later visitors to any waste site. they recommended that messages include each of the following, gradually increasing complexity.

{much more under the cut.}

"1} Rudimentary information: "Something man-made is here"

2} Cautionary information: "Something man-made is here and it is dangerous"

3} Basic information: Tells what, why, when, where, who, and how

4} Complex information: Highly detailed written records, tables, figures, graphs, maps and diagrams"

the issue with worded messages is that they're unlikely to be comprehensible in thousands of years. considering how much the english language has changed, and will continue to evolve, would those of the future be able to understand what is being said? because of this, symbols were also considered.. but another problem arises with that. no symbol will be universally understood to mean one thing, even something such as the jolly roger. {☠️} using it to warn for risk of sickness, or general harm would serve useless as time passes. especially nowadays, while the jolly rodger still is seen as a danger symbol somewhat, is used more commonly as a cool design thing.. at least in the USA. and again, that's the problem. no symbol is universally known for one thing, no matter what.

i believe it was also a thought to not warn at all, and just leave it there.. but that questions ethics.

eventually, physical markers were explored, giving ideas such as the forbidding blocks, rubble landscape, the landscape of thorns, and a few beyond those. these ideas carry similar characteristics to each other.

from the official trailer.

in 1992-1993, a poll was issued by the zeitschrift für semiotik of tübingen germany, asking the following question:

"how would it be possible to inform our descendants for the next 10,000 years about the storage locations and dangers of radioactive waste?" and received answers such as artificial satellites, atomic priests, and 'ray cats.' i'm going to further talk about ray cats, as i think, considering the themes, it would be a good opportunity for side order to delve deeper into li'l judd, and his current whereabouts or motivations. as it's very vaguely hinted that he owns grizzco industries, and with that presumably dead fish in the trailer, it could be explored. i hope they won't make it weird though, as you know.. the whole thing with mammals has been a bit bizarre..

anyway, it was suggested that a species of cat should be bred that changes colors when exposed to radiation, so essentially a living sign of nuclear threat. as things such as nursery rhymes have been culturally significant in some way for many, many years.. in 2014, the musician 'emperor x' was commissioned by the podcast '99% invisible' to create a song about this idea for an episode about long-term nuclear waste warning messages.

whatever this fucker is. they could be completely done with grizzco, but who knows.

{edit 8/23/23 i've been told it resembles the bake-kujira. the ghost whale which is accompanied by "weird birds or fish."}

giving us the song '10,000-Year Earworm to Discourage Settlement Near Nuclear Waste Repositories {Don't Change Color, Kitty.}' the gist of this track being "if the cat turns bright colors, run!" and was designed to be "so catchy and annoying that it might be handed down from generation to generation over a span of 10,000 years."

so, themes of radiation are very likely to be present. this brings us to our next section, the coral bleaching.

as you may know, healthy coral has beautifully bright colors. this is due to microscopic algae known as zooxanthellae, which lives inside of the algae's polyps. it is also a major source of food, and nutrients. coral bleaching occurs when coral reefs are under stressful conditions, a huge one being climate change, which i will get deeper into that specifically. if the waters it lives in heat up too much, the coral will begin to expel this zooxanthellae.. leaving it completely white, and exposing its bone-like structure.

healthy vs partially bleached coral.

while bleached coral isn't quite dead, the aftermath of said bleaching makes it much more susceptible to disease and malnourishment due to lack of nutrition. if the waters stay too warm for too long, or if the bleaching is too extreme, the coral will die.

images from the official side order trailer, showing us bleached and possibly dead coral.

coral bleaching is an ongoing issue, and efforts have been made to conserve and regrow the coral reefs.. this brings us to a shorter section, but one worthy of a mention.

coral cloning. coral cloning is a phenomenon where a small bit of a healthy coral is cut, and grows into a full piece. it helps when this, sometimes miniscule, piece is placed next to another. this speeds up growth almost rapidly. however, it is not too easy to grow, and this method isn't totally fool-proof. coral requires very certain conditions to flourish, such as not being placed on an open ocean floor, but instead in an already established habitat. also things like water temperature, pH levels, pollution, all can stunt growth. this is a very vast oversimplified explanation, but i believe you get the picture. have you wondered why i am bringing this up? here is why..

am i saying this directly implies cloning? not exactly. it's an interesting thing to note, though, as you might know how octarians {NOT OCTOLINGS!} are born.. via severed tentacle. coral can sometimes be born via severed piece. i'm not going to go into this much more, as it's kind of an out-there comparison. do with that what you will.

continuing on with the radiation and infectious theme, i feel i should mention ultraviolet radiation. the sun produces these UV rays, of course, and they can be good in moderation. if it's too much? it can be absolutely killer. you guessed it, ultraviolet radiation does play a part in warmer waters, which aids in bleaching coral. however, that's not all.. the state of inkopolis square we see in the side order trailer could very well also be due to residue of nuclear radiation from the human society's many wars. before humanity's fall, natural disasters were more prevalent than ever, and we still don't really know what exactly happened besides the massive flood. the sea levels rising was the reason the great turf war, the deadliest war to strike inkadia, even happened. things like oil spills could possibly be going on too, as in some photos, you can see this black liquid.

i'm going to state the obvious and add on that oil spills are incredibly dangerous to marine life, and that includes coral reefs.

remnants of human life have not disappeared from inkadia, or anywhere in this world dominated by marine life. it's not far-fetched to say they could still be affected by anything else left behind, climate wise.

the landscape of thorns has not been built, to my knowledge, but maybe it was here. this could be a rediscovered nuclear plant, who knows. especially as certain kinds of radiation, again, can stay hazardous for upwards of ten-thousand years, and possibly longer. you may have caught that ten-thousand is an important number for multiple reasons, especially with the possibility that this octoling is eight. the human race has been extinct for longer than ten-thousand years by this point, but it's something to remember. but there's still questions.. where do pearl and marina fall now? what is their role? is this an infection only targeting octolings, and other octarians? what's going on with marina? only time will tell, yeah?

there you have it, if you read this far.. definitely tell me what you think. i've still not covered everything in the trailer, so any add-ons would be cool if you have any. this took a while to research and write, so thanks for reading.

meowdy ny'all. you might have seen that there was big news today for nuclear fusion! and indeed, it is a pretty big deal. here's a little bite-sized summary if you're interested

tl;dr -- this is the first time humanity has performed a (controlled) nuclear fusion experiment that produced more energy than we had to use to make it happen.

on December 5th, 2022, the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) was able to perform nuclear fusion with a bunch of lasers focused at a small capsule.

this is NOT the first time humans have done nuclear fusion; plenty of other experiments and facilities have done some amount of fusion.

one of the most well known examples (unfortunately) is the hydrogen bomb, which unleashes energy from nuclear fusion in an uncontrolled manner.

what NIF did is cause a fusion reaction that produced more energy than they had to use to power the lasers that made it happen. this release of energy was in a controlled fashion, too, although it was not actually used in this case of course, just measured. THAT is what makes this experiment so good

how much energy? well, the lasers and other devices took about 2.05 mega-joules to power. the energy released was measured to be 3.15 mega-joules, which means about 1.1 mega-joules of energy were gained!

for perspective, that's about the same amount of energy as 60 cellphone batteries at full charge. NOT A LOT, but that was from one little fuel capsule. it will take a lot of work to make powerplants operating on this principle (Inertial Confinement Fusion), but it's a big step, and certainly outperforms what is being done with tokamaks (sorry tokamak researchers, i was almost one of you but the funding got cut).

if you're hungry for more, here's an article from the lab where the experiment was done:

#i do particle accelerator stuff nowadays (it rocks) but you can also message me if you want to discuss fusion more #(i reserve the right to ignore you if you are a crank) #anyways big news! but also dont think that all of our problems will be solved with fusion we should use wind solar geothermal and hydro too #a wide selection of power sources is best #science #nuclear fusion

Pentagon plans to develop new variant of the B61 gravitational nuclear bomb

Fernando Valduga By Fernando Valduga 11/01/2023 - 11:00am In Armaments, Military

The U.S. Department of Defense (DoD) announced that the United States will develop a modern variant of the B61 gravitational nuclear bomb, designated B61-13, pending authorization and appropriation by Congress.

The National Nuclear Safety Administration of the Department of Energy (NNSA) would produce B61-13. The decision to pursue this capability, which was taken in close collaboration with the NNSA, responds to the requirements of a rapidly evolving safety environment, as described in the 2022 Nuclear Posture Review.

The Pentagon announced that it plans to develop a new gravitational nuclear bomb to respond to the evolving safety environment, but it is not immediately clear why more free-fall nuclear bombs are needed in preference to missiles launched from the air with a nuclear warhead. (Photo: USAF)

“Today's announcement reflects a changing security environment and growing threats from potential opponents,” said Deputy Secretary of Defense for Space Policy John Plumb. “The United States has a responsibility to continue to evaluate and put into practice the capabilities we need to credibly deter and, if necessary, respond to strategic attacks, and secure our allies.”

The B61-13 would be delivered by modern aircraft, strengthening the deterrence of opponents and the safety of allies and partners, providing the U.S. President with additional options against certain more difficult and large-area military targets. It would replace some of the B61-7 of the current nuclear arsenal and would have a yield similar to that of B61-7, which is higher than that of B61-12.

“The B61-13 represents a reasonable step in managing the challenges of a highly dynamic security environment,” Plumb said. “Although it provides us with additional flexibility, the production of B61-13 will not increase the total number of weapons in our nuclear arsenal.”

The B61-13 would take advantage of the current and established production capabilities that support the B61-12 and would include the modern security, protection and accuracy features of the B61-12.

This initiative follows several months of review and consideration. The field entry of B61-13 is not a response to any specific current event; it reflects a continuous assessment of a changing safety environment.

The information sheet of the request can be read here.

Montauk is at the tip of the Long Island peninsula, it’s a strategic place, and in particular to protect NYC. We can imagine it being a place of battles, traffic, etc., at least in the past, and it’s understandable that the Army built a camp there. But Hawkins, Indiana? It actually appears rather suspicious, and we saw that the Russians were spying on them. Maybe there’s an interview where the Duffers explained why they abandoned the idea of Montauk for a fictional small town in the Midwest but I don’t remember it. Maybe it was just a logistical choice ( bc they had to film in GA?) and not a creative one.

It was definitely the logistical choice. It was way to expensive to film or sight and finding a similar location is probably next to impossible. So if I recall correctly, they went with a small town feel like when they grew up (though I think they grew up in NC). As for why Indiana when they film in GA, GA has tax credits and other than the red soil that is easy to hide, they look pretty similar.

A small town set up is very similar to 80 movies we consider classics now. A normalish little town with normalish people and then the wildest shit just happens. It lines up pretty well with that setting.

Also I want to note having a department of energy in some random town isn't like, weird or unrealistic. In reality, these department locations aren't a secret. They're even listed on the official website.

The secret part was an experiment like that happening at all I feel. Even if the Russians knew the experiments were happening, they'd have to stake out the handful of locations around the US. We've got random places like Missouri so Indiana isn't odd.

In fact, maybe the Missouri location was inspiration for Hawkins. No offense to Missouri but I've been there dozens of times and I don't remember a single thing of significance being there just like there is nothing in Indiana. (Maybe as someone from Illinois I am being extremely biased since the only thing in Illinois is Chicago but YOU KNOW IT IS WHAT IT IS)

Exclusive: Laser-fusion facility heads back to the drawing board

Nearly one year ago, scientists at the world’s largest laser-fusion facility announced a landmark achievement: it had shattered all records and produced, if only for a fraction of a second, an energetic fusion reaction of the kind that powers stars and thermonuclear weapons. Yet efforts to replicate that experiment have fallen short. Nature has learnt that, earlier this year, researchers at the California facility changed direction, moving to rethink their experimental design.

The turn of events has renewed debate about the future of the National Ignition Facility (NIF), a US$3.5-billion device that is housed at Lawrence Livermore National Laboratory and overseen by the National Nuclear Security Administration (NNSA), a branch of the US Department of Energy that manages nuclear weapons. The NIF’s primary mission is to create high-yield fusion reactions, and to inform maintenance of the US weapons stockpile.

Probably not the person to ask, but I saw your post about fusion being used to further nuclear weapons, isn't one of the main points for nuclear fusion that it can't create radioactive materials used for nuclear weapons? Even the existing thermonuclear bombs still need fissile materials in order to trigger the actual fusion. It seems like fusion can't really be used on it's own offensively, though if you have sources that say something else I'd love to see it.

hiya! sorry, but im gonna somewhat hijack this ask to answer some things ive seen people talk about in reblogs (ill still answer the question though :D!)

first of all, i would like to make it clear that i am not a scientist, and i am not qualified to understand all of the mechanics behind nuclear fusion. the intent of my original post was not to add more fearmongering about nuclear weapons, and i believe i definitely could have worded it better. i merely wanted to point out that the NNSA was involved with these studies, which makes me, personally, very wary, as if they are involved that may mean they see some application of this science for defense purposes. in the original post, i believe some of my distaste for nuclear weapons added to a more accusatory, fearmongering tone, and for that i apologize.

and, i apologize for taking this long to get to your actual question, but! quoted from the article on the lawrence livermore national lab's website:

" ... like the team at NIF — whose work will help us solve humanity’s most complex and pressing problems, like providing clean power to combat climate change and maintaining a nuclear deterrent without nuclear testing.”

this is quoting a statement made by the secretary of energy. while nuclear fusion cannot make nuclear material, that is not what i believe this research will be used for. the knowledge gained about the physics behind nuclear fusion could, theoretically, be applied to understanding the physics behind nuclear fission and, possibly, be used in weapons research.

again. i am not a scientist. i am an artist. i do not spend my time reading research papers, nor do i want to. i respect scientists a great deal, and have personal ties to the field of physics, which compelled me to make the original post. i do not know how a lot of this stuff works. i have an interest in it, sure, but that does not compare to actually studying it for years. the intent of the original post was not to get into the science behind it, it was to clear up some misinformation and add some clarifications that i believe many articles did not properly convey.

god that got longer than i wanted it to. never really expected the original post to get much response, if we're being honest. but honestly, im glad for it, if it means it reaches more people!

#asks #teggxtpost #and thank you for the good faith question!! #which i was definitely not prepared to get at all haha #i dont know how a lot of this stuff works but i am always suspicious of bad journalism #which i believe a looooot of the articles out there are #i know that the field of science and journalism dont really get along #and i understand that having a buunch of people interested in nuclear fusion #is really cool and good!! #i am just a very... very cautious person

[deadlysprinklez]

YO???????

Okay to summarize this basically means that we've figured out how to do things that stars do on a smaller scale on Earth, and we've gotten a net positive gain (~2MJ in -> ~3MJ out) of energy from it. This could legitimately revolutionize green energy.

Don't let this get buried. Don't let this get misconstrued. This is massive. I don't want to see this get the Nuclear Energy treatment of fearmongering and mass public denial.

對中(共)國禁運的超級計算機，2017年03月。是舊聞，撫今感昔的舊聞。仍有一看價值。。。。

2016年國際超級計算機TOP500組織榜單顯示，排在榜首的是由中國國家超級計算無錫中心研製的「神威·太湖之光」，原來排第一的中國天河二號屈居第二，中國入榜的超級計算機數量達到167台，美國則是165台，其他國家168台。（全球超級計算機500強中國雙第一）。

神威太湖之光與之前的超算相比，最大亮點是全部採用自主中國芯：「申威26010」眾核處理器。Peak performance 3TFLOPS DP per chip: (每秒雙精度浮點運算3x10^12次/每晶片)，性能較高，與Intel的Knights Landing many core一個量級。

相關團隊基於全球最快超級計算機「神威·太湖之光」系統的三項全機應用入圍國際高性能計算應用領域最高獎——戈登貝爾獎。該獎設立30年以來，中國團隊從未入圍。此次，基於「神威·太湖之光」系統研發的三個課題入圍該獎項，占入圍總數一半。

1、太湖之光，Sunway MPP，SW26010，國家超級計算中心，中國無錫，1060萬個核心，93.01pf(每秒千萬億次運算)

2、天河二號，TH-IVB-FEP Cluster，國家超級計算機中心，中國廣州，312萬個核心，33.86pf

3、泰坦，Cray XK7系統，美國能源部，橡樹嶺國家實驗室，17.59pf

4、紅杉，IBM BlueGene/Q系統，美國能源部，勞倫斯利弗莫爾國家實驗室，加州，157萬個核心，16.32pf

5、Cori，Cray XC40，伯克利實驗室，美國國家能源研究科學計算中心(NERSC)，14pf

6、Oakforest-PACs，富士通Primergy CX1640 M1 cluster，日本，先進高性能計算聯合中心，13.6pf

7、K Computer，SPARC64系統，70.5萬個核心，日本，Riken計算科學高級研究所，10.5pf

8、Piz Daint，Cray XC30,11.6萬個Xeon和英偉達核心，瑞士國家計算中心，瑞士，9.8pf

9、Mira，IBM BlueGene/Q系統，美國DOE/SC/Argonne國家實驗室，78.6萬個核心，8.6pf

10、Trinity，Cray CX40，美國DOE/NNSA/LANL/SNL，30.1萬個核心，8.1pf

檢測是由國際TOP500組織完成的，排行榜也是由該組織發布的。TOP500組織在聲明中表示：「除了超級計算系統數量上的對決之外，中國和美國在Linpack性能上也表現出並駕齊驅的態勢。」美國占到全球超級計算能力總和的33.9%，排名第一;中國以33.3%的份額緊隨其後。全球最大的500台超級計算機的運算能力總和為672pf，比去年的運算能力總和增長了60%。

IBM是超級計算機CPU的最大製造商，AMD排在第二位，但其市場份額僅為7%。上榜的所有超級計算機有96%都使用了配備英偉達GPU的核心加速器，它所占份額為60%。緊隨其後的是Xeon Phi，所占份額為21%。共有206台超級計算機系統使用了Gigabit Ethernet，187台超級計算機系統使用的是Infiniband，使用英特爾最新Omni-Path技術的超級計算機系統數量由去年的20個增加到28個。見不得好的美國在背地裡使壞，藉助與其點亮科技樹的優勢，決定對中國四家國家超級計算機中心禁售至強PHI計算卡，當時各種唱衰中國超算的聲音不絕於耳。即便天河2號在2015年國際超級計算機大會上蟬聯5連冠，但因使用美國Intel公司的CPU而飽受一些別有用心之人的詬病，不少人聲稱沒有美國的CPU，天河2號要完蛋了。

網友調侃，在超級計算機領域，中國超過了美國，不過還有一個其他國家還沒有超過，這真的是在中國人眼裡，只有兩個國家，那就是中國和外國！要知道，這次的太湖之光用的是國產晶片。中國的「天河二號」超級計算機自2013年誕生以來，就一直雄居全球超級計算機500強榜單之首，這弄得美國很沒面子，很不淡定，於是在2015年美國發飆了，那就是美國禁止Intel向中國發售高端伺服器晶片（美國禁售CPU未能阻止中國在超級計算機上稱王）。沒想到，中國第二年就出自主晶片了，還是得了第一，看來深得獨立自主，自力更生發展精髓，能買也要能造，這也是國人對航空發動機的要求

可以說，隨著中國經濟和科技的發展，中國打破西方壟斷的技術會越來越多！這也是中國經濟發展，要提高人均GDP，達到中等發達國家水平所必須要走的一條路。另一方面，中國也不會滿足於跟隨西方的步伐，而是追求在一些領域處於世界領先地位，引領世界潮流。比如量子通信領域，中國就處於世界領先地位，發射了首顆量子通信衛星。感謝那些為中華民族復興而默默做出貢獻的科學家，正是因為你們的辛勤奉獻，才有我們的闔家安康。

US Department of Defense Announces Pursuit of B61 Thermonuclear Gravity Bomb Variant

The U.S. Department of Defense (DoD) announced that the United States will pursue a modern variant of the B61 nuclear gravity bomb, designated the B61-13, pending Congressional authorization and appropriation. The Department of Energy's National Nuclear Security Administration (NNSA) would produce the B61-13. The decision to pursue this capability, which was undertaken in close collaboration with the NNSA, responds to the demands of a rapidly evolving security environment as described in the 2022 Nuclear Posture Review. The B61-13 would take advantage of the current, established production capabilities supporting the B61-12, and would include the modern safety, security, and accuracy features of the B61-12.
