The Wordsmith's Forge

Nifty - I'd previously heard of the non-FTL solution (which would still be useful if it could hit relativistic velocities, since getting up to relativistic velocities with reaction drives is seriously hard), and had not known there was a solution that permitted FTL but didn't require negative energy. Of course, the one downside of the idea that FTL is possible is that it removes the most likely solution to the Fermi paradox that still permits our galaxy to have multiple intelligent species (if FTL is impossible and STL travel is *really* difficult, then there's nothing like a Fermi paradox). If FTL is possible, I suspect it means humanity is alone in the galaxy, which is I find quite sad.
