And can you travel to that fixed point after the black hole has its way with it? And if the velocity of a black hole is so intense that it exceeds the speed of light, then would that mean we have a new speed to consider? If so can you explain what speed is that is faster than light?
Forgive me still have a knowledge boner…no sarcasm. But in your comparison then if a black hole is like a funnel then at the edge of it has a certain speed and speeds up when you keep going deeper? So in someway (hate to bring up fiction) Interstellar was correct or semi correct in it’s portrayal of a black hole going into it? (not the timey wimey stuff). But with gravity being so strong if it warps space then that mean’s just looking at one should give a viewpoint of something that is distorted to all around it? But the question I ask is the event horizon of a black hole…is that the way we can view speed through that lense, but with that said any event horizon at least should have an escape velocity like we have on earth? …on a side not thank you for having a civilized discourse with me. It’s hard to find. …much love and if I don’t reply have a great weekend.
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.
