Reply to comment by dastardly740 in Black hole question by Impossible_Pop620

See...maybe I am confused, but the event horizon itself is not anything physical, just an arbitary boundary where inside it requires an escape velocity faster than light...

You are thinking like space elevator where something pulls just a little harder than gravity can make its way up. Basically, if you apply a force of 1.0001g constantly from the earth's surface you move up from the earth's surface. There is no x.000001g that allows any object to move up inside a black hole event horizon.

If this were true...hmmm...then ALL black holes would have the same mass?

More massive black holes have larger event horizons.

...and of course, this is impossible. But this is from the POV of a rocket or similar, trying to escape the EH from inside, not something with outside connections.

...ie, a space elevator on Earth would not need to travel at escape velocity, right?

You’re under a presumption this fictional cable and camera still exist past the event horizon.

They stop existing physically. They’re gone. And if you’re stationary and not orbiting to be able to lower this in, you’re about to be gone too bro.

Orbiting and lowering this in, it would “spaghettify” perceptually.
