I don't know if this thread is still active or not, but if it is, just a quick thing to throw out there... The Alcubierre Warp Drive... I did a class paper on FTL travel a while back and this was one of my sources... Very interesting one too...

The two only seemingly viable methods I found were either through the creation of a stable wormhole and passing a vehicle through it (Requiring MASSIVE amounts of energy to keep open) or through space-folding such as this paper, requiring an exotic source of energy... I've seen the Casimir Effect tossed around very frequently as a solution to this (and wormholing), but it is an effect based on a very, very small scale (Look up Zero Point Energy if you're not familiar with it) and not on the large scale this would require... as far as for what I've come across, nothing looks good in that regard... anyone else come across some good information on this? And any other reasonable methods of FTL travel?
