There is a innumerable number of questions on this site about black hole event horizons, the possibility of falling in and back out again, but none of them answer my question specifically.
I have read this question:
The confusion arises because it also has an external mathematical surface, called the ergosphere, where in fact it is possible to come in to and still come out. This ouTer surface in not a true horizon, but it is a surface inside of which a particle (or ideal observer) has to rotate with the BH. Penrose determined that it is indeed possible to come into the ergosphere with a certain energy and come out faster, with a higher energy. This is conceptually a way to extract energy from the BH. But the more important surface for the question is the event or inner horizon. It is a true horizon and if you go inside it you can never. Come out.
the charged and rotating black holes have the complication that there are two horizons and the singularity is timelike not spacelike, and an observer can fall in through the two horizons and back out of the black hole again.
Now the first one says, what I always have read on this site everywhere, that is, if you enter the EH, you can never return.
But the latter states, that if you fall through both horizons, that includes the inner one (the real EH), then you can fall back out again.
1.Is it possible to fall into a black hole (through the real EH), and then back out again?
