Reply to comment by Impossible_Pop620 in Black hole question by Impossible_Pop620

You're still thinking that these things would just basically be forced towards the center of the BH really hard, but that's just not how black holes work. The definition of the event horizon is literally that nothing can escape it once that thing crosses the threshold. It would take infinite energy to winch the capsule back up, if it magically survived (which it wouldn't) and anything inside the capsule would be exposed to such extreme forces the data would be unrecognizable.

Yes! Now you're talking...not the infinite energy bit, tho...why?

You would need the capsule to travel FTL to escape the event horizon, which requires infinite energy.

And FTL travel comes with its own bag of paradoxes.

Also, I have a better understanding of black holes now after reading through some of these comments. This thread was surprisingly fun.

It's all explained by Einstein and relativity. It takes an infinite amount of energy to reach the speed of light. The event horizon theoretically is the point at which light can't escape the dead star and it's gravity. You would need an infinite amount of energy to pass back out of it. There are plenty of good books that you can pick up and read about it friend

Nevermind all the bs comments you are going to get for asking questions. I am proud you aren't asking what the Kardashians are upto this week. Keep thinking. Ask questions. This world needs more of you. ❤️

I think I would take issue with the word 'explained'...more like 'unleashed'...but thank you.

Wtf does that mean? If this turns into a God thing I'm gonna be pissed.

Lol..yeah, he MADE us, you know...no, I meant I don't think relativity EXPLAINS black holes very well/at all

Relativity "unleashed" to us the energy and mass can be converted. Nothing is ever gained or lost. If you burn an egg and collect all the ashes and heat and light and weigh the findings, it would add up to the weight of the egg. If you take enough mass in a relatively small place in space. It will press down (but you have to think in a 3D sense) hard enough that nothing can climb of that hill and get out.
