Why does nobody talk about the fact that Danny, a 14 year old JUST CASUALLY WENT TO SPACE??
He didn’t even use a rocket or anything, just a fancy jet-pack
(There was also wrong physics, like when the jet pack engine stopped, he didn’t keep going at a constant speed, he kinda slowed down and started spinning, that’s not how space works)

We need to talk about how so many queer spaces are inaccessible and even actively hostile to physically disabled people.

Because light has a speed and relative speed is your speed plus the speed of things coming towards you, assuming the universe isn’t expanding , time dilation didn’t exist, and the speed of light wasn’t relative, if you went to a distant galaxy at the speed of light, you would watch the galaxy move and do things twice as fast as it actually is because compared to you, the speed of the light moving toward you is twice as fast as the speed of light.

So apparently on December 11th NASA tested using lasers to send information from space to Earth and this was the video they used:
youtube
The first video to be sent from space to Earth via laser is of an orange tabby cat chasing a laser pointer. His name? Taters.

Kerbal Space Program was once afflicted by a bug the fans dubbed the "Deep Space Kraken", whereby if you travelled far enough from the origin of the game's coordinate system, floating point rounding errors would cause your spacecraft's components to become misaligned and/or clip into each other, resulting in the craft falling apart or exploding for no obvious reason.
The bug was later fixed by defining the active spacecraft itself as the origin of the game's coordinate system. In effect, the spacecraft no longer moves; instead, the spacecraft remains stationary and the entire universe moves around it. Owing to how relativity works, to the player this is indistinguishable from the spacecraft moving about within a fixed coordinate system, and it ensures that the body of the craft and its components will always be modelled with maximal precision.
While elegant, this solution introduced a new problem: it was now possible, by doing certain stupid tricks with relativistic velocities, to introduce floating point rounding errors to everything except the active spacecraft. In extreme cases, this could result in the destruction of the entire observable universe.
Some might call this one of those situations where the solution proves to be worse than the problem. I call it a perfect expression of what Kerbal Space Program is truly about.

Dp x dc AU - If the Internation Space Station orbits the Earth 16 times a day, then so does the Watchtower.
Danny’s on track to move out of his parent’s house and move to Gotham for college (He swears that Sam bribed the board to let him in- and she wasn’t even going to that university!) but the dorms don’t open for another three days and he cannot wait to escape. Seeing his parents try to perfect yet another weapon to use against him while he changed out the ecto filters on the portal was too much. He’s completely over the idea of staying when he already has everything packed and ready to go.
The solution? Take all his boxes into his haunt in the Ghost Zone, leave them there and then spend some time in camping in space. He’s already explored the Infinite Realms enough to be bored of it for a minute (not to mention he wants to avoid getting more ‘favors’ to do from Clockwork) and hell, he just wants to see some stars.
He grabs his tent, a sleeping bag and all the food and things he could need and brings it into the atmosphere with him. Keeping it all tethered to him, Danny stays in a fixed position above Gotham (Cause that’s where he’s going next, duh) and treats himself to some quality Me-time.
Only problem is that several times a day he has to make himself intangible while he lets satellites and things pass through. Easy enough and honestly pretty interesting to observe as a wannabe engineering student.
He doesn’t know when exactly it happened the first time- but it turns out the Heroes of Earth all congregated in a satelite office building? It was bigger than the ISS! What the heck!?
Going intangible but not invisible, the JL spot Danny and are incredibly confused how an ‘Alien’ teen just happens to appear in their meeting rooms disappearing at the rate (slowly but surely) of the Watchtower moving through space. Was that camping gear? How was he roasting a marshmallow? Did propane camping stoves even work in space??
16 times a day they get the opportunity to ask Danny a few questions. He mostly ignores them or gives them joke answers. Eventually Martian Manhunter phases through the Watchtower to join him.
They talk about how hard transition periods in life can be and having strained relationships with family. J’ohn returns to the watchtower on its next cycle and reports that the kid is just fine, being an adult is just a hard thing to do.

biological differences between men and women are inherently neutral. they do not indicate male superiority over female people. to suggest so is inherently sexist. to complain when female sports cater to female anatomy - such as the smaller balls in the wnba because women tend to have smaller hands - is what sexists do. they want women to be forced to prove ourselves according to standards designed for men because they want to see us fail. it is sexist to argue that women who wish to compete on their own terms are pronouncing themselves as inferior. nobody said that but you. because you’re a sexist that hates women
