Once you’re inside the horizon, r is a timelike coordinate, and t is a spacelike coordinate. So any point a greater distance from the center than yourself is in the past (or at least, not in the future), and the center is in your future. So you can no more get further out than you can travel back in time. Really, you can’t even slow yourself down: If you want your clocks to pass the most time before you reach the center, the absolute best you can do is to just let yourself fall straight in. Anything else will just hasten your demise.
This reversal of space and time also helps clarify the Universe-as-black-hole scenario. If the Universe is closed, then there’s a singularity at the end of time, the Big Crunch, where everything in the Universe ends up. This end singularity behaves in the same manner as the central singularity of a black hole, where everything in the hole eventually ends up.
Chronos, that’s intriguing. Why can you not even slow yourself down? Intuitively, it seems that throwing your engines on full reverse would cause you to slow your approach to the singularity. Why is it that the longest duration path to the singularity is falling straight in?
You’re thinking, just point your engines towards the center, and then fire them? Consider this: In ordinary (non-black-hole) space, you’ve got a spaceship out in the middle of nowhere. Point your ship’s engines towards next Thursday.
Not that Star Trek has anything to do with reality, but the very first episode of ST shown on TV had the Enterprise reach and cross the “edge of the galaxy”, which was some sort of energy barrier. Then they crossed back. This had the effect of making certain crew members get strange mental powers, requiring Kirk to end up fighting the one with the most powers on a planet and end up losing his shirt. Thus establishing a pattern (i.e. losing his shirt in fights).
A corollary of this of course was that whilst Kirk invariably ripped and lost his shirt in the course of conflict, he somehow managed to maintain a secure grip on his hair-piece! Something that has baffled xeno-trichologists the universe over
