Like practical nuclear space ships producing enough Gs for passengers to be uncomfortably thrust into their acceleration couches? Or what about FTL subspace communications? For that matter, what about FTL propulsion at all? I recall reading a lot of science fiction about time travel, yet that still remains firmly out of reach, unless you've figured out how to create negative energy (energy is, after all, the generator of the time translation genorater in Hamiltonian systems).

If you'd like to link to primary research concerning the subject matter, I'll gladly read and consider it. Otherwise, I suppose I've said all I have to say.
