  In regard to speed, the speed of light is actually the speed of causality, which is the absolute limit at which one event can influence another. It is an absolute speed limit. Light can travel at this speed limit because it is a massless particle/wave. Anything with mass would need to have infinite energy to travel at the speed of light because the faster something is traveling, the more energy it takes to accelerate it further.

  Inside the event horizon, these same rules apply because it is still space and time inside the event horizon. Even light that is traveling at the speed limit cannot escape. You just can’t go fast enough to escape once you are inside the event horizon, because the speed limit of the universe prevents you from going fast enough to escape. Basically you would be on your way to being spaghetti-fied as you approach the black hole, or maybe not. There is a whole lot we don’t know about the inside of black holes, so who knows what could happen in there. There are theories that say that super massive black holes could have different effects on things, but I only know of them and not how to explain them.

  Outside of the event horizon, you can technically escape by accelerating away. But it would require so much energy that you wouldn’t want to cut it close, I would think.

  Gravity does bend space and that does cause light to curve along with space. If there’s enough mass, it can bend space enough to essentially make a lens that can magnify light coming from behind. A black hole can bend space so much you can see the opposite side of its accretion disk above and below the event horizon.

  If you’re interested, I watch a lot of Antov Petrov, Cool Worlds, Dr. Becky, and PBS Space Time on YouTube. That’s where I have learned most of this stuff. PBS Space Time can be a bit hardcore sometimes, but they have tons of information.

  Black holes warp the fabric of space so much that not even light can escape once it passes the event horizon.

  It has nothing to do with speed, it’s simply that all possible paths lead into the black hole. Photons travel through the fabric of space like a car on a road. The car can’t go off the road, so if the road curves, the car will have to curve with the road.

  There’s a lot more to it, but the most simple way to think about it is that a black hole’s gravity is so strong, it warps space itself. And this warping of space basically acts like a funnel that funnels everything to the center of the black hole. Once an object or particle or whatever passes the event horizon (the point of no return) it is basically being funneled into the black hole by the fabric of space being twisted into the black hole.

  I don’t think you’re to stupid, I think this game is too stupid to figure out.

  I played the first puzzle, apparently “Right” is supposed to stand for the letter “R” for some reason. That’s just fucking stupid right there.

  No, that benefits society as a whole by increasing education for the next generation. Which leads to better lives and more opportunities.

  When something benefits the whole, not all individuals will see obvious benefits to themselves. But they still get to benefit from the outcomes, like better jobs more opportunities and such.

• ⁨Comment⁩ on ⁨Everything has a bit of overlap⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:

  Oh man, one of my biggest pet peeves.

  “Observation” should really be called “interaction” when referring to quantum effects. The act of observation is actually an interaction with a quantum object that collapsed the wave to a point. We are affecting the quantum object by making a measurement, not by looking at it. If we don’t measure it the wave function doesn’t collapse until it interacts with the wall. In this case, the wall is the “observation” that causes the wave function to collapse.

  Ok, sorry for the interruption, carry on

  Here’s a wonderful thing about the internet, you don’t have to give a fuck about it.

  If you get off the internet and go to the store, no one is going to give a fuck about what some idiot said about you online.

  If you go to visit family, none of them are going to ask you about what some goddamn dumbass said about you online.

  My advice is to stop stressing about what people say about you online. It has no value, there is no substance to it. Nobody on here knows you, no one knows what makes you, you. You’re just text on a screen here.

  No, they admitted the mistake to Billet Labs and asked them to send a bill to compensate them for the loss. LTT paid that bill.

  “Stole a prototype” is unfair language, they made a huge mistake and auctioned off the prototype. Linus admitted the mistake to Billet Labs and paid them for the prototype.

  You should know that undercooked beans can be poisonous, and it is best to soak them before cooking.

  If you do try this please prepare the beans properly first.

• ⁨Comment⁩ on ⁨Those poor plants⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  Fun fact, humans share more DNA with fungi than they do with plants. We share nearly 50% of our DNA with fungi.

  Plus mushrooms are the sex organs of the mycelium organism. Just an extra fun fact for free there.
