| HELP! (escape Velocity And Inner Event Horizons)

People say that it's impossible to leave the black hole once you enter it because past the event horizon the escape velocity is over the speed of light, right? Kinda like the escape velocity of Earth is 28,000 mph or something. But that is only for something traveling under its own momentum, right? You could theoretically get on a 50 mile high elevator on Earth and ascend into space at 10 miles per hour. By that logic, why can't you be "pulled" out of a black hole by some external force? Also, what are inner event horizons and why do they exist? The event horizon is the place where light can no longer escape the black hole, so how can a hole possibly have a second one? I thank you very much for clearing this up for me. |
