What's wrong with the following method of escaping from inside an event horizon (and possibly exploring physics inside it?)
1. A rocket with a very strong engine slips below the event horizon -- just barely.
2. Fire the rocket engine so it would travel at c-epsilon were it not for the hole. Since you are inside the horizon, you will slowly start to fall in. But you can make it arbitrarily slow.
3. The black hole's radius will decrease over time due to Hawking radiation. If the rocket falls inward more slowly than the event horizon, suddenly it will wind up outside the hole as the horizon moves back over it.
4. The rocket escapes with its observations.
Ignoring the fact that such an escape would be impractical, where does it go wrong when it comes to special relativity? My guess is that the event horizon can never retreat inward faster than the falling object, but who knows...
Thanks in advance,
