but that means time travel,
NO IT DOESN'T. I REALLY wish people would stop saying these things.
Using traditional methods of propulsion to accelerate in normal space-time causes time dilation.
The formula entirely falls apart when you hit the speed of light which according to the formulas in question require infinite energy.
FULL STOP.
Leaving one location and arriving at another faster than light traveling through normal space does not require that you do exactly as specified above.
If you can avoid the acceleration portion, its a whole new ball game.
If you can avoid traveling in normal space-time, then you've just potentially solved the problem entirely.
Neither of these two things have been proven impossible, although very improbably for the former.
A blackhole is already not normal-space time, the formula in fact breaks down inside a black hole. A wormhole (which can mean any number of things) connecting two black holes? Thats pretty far from normal-space time and certainly, in theory, allows for things such as leaving point A and arriving at point B before the light traveling between the two does.
Light does not travel in time at all from its perspective.
You can't fly a 747 by shooting a jet of water from the top of it up into the sky, you can make it fly using all the other normal aerodynamic principles that keep us as happy fliers. Just because you know it won't work one way doesn't mean their isn't a way we haven't discovered yet to accomplish the same thing from a practical perspect, and you really should stop implying that FTL == Time Travel. The equations that produce that 'theory' break down at the speed of light, so you can't use them to make assumptions about what happens after that.
