[QUOTE="DarkKestral, post: 3122038, member: 40100"] Nah, it's actually got a fair bit of hard sf in there, but you gotta look close! Ignore the gravity stuff. It's technomagical. Go for the mutations, nanobot descriptions, and PL 6-PL 7 non-gravity or cold-based weapons. A lot of that stuff's possible, and the descriptions of possibilities associated with them is actually pretty accurate. Just stay well away from FTL, gravity-based technologies, and lightsaber-type stuff. As for FTL, people have actually thought up potential ideas. It's just the energy costs are enormous, and would involve things like instantaneously storing 90+% of the energy produced when an entire solar system would be converted entirely to energy by reaction with an equal mass of anti-matter. Thus, it's considered beyond impractical, as you would need near perfect energy collection AND transmission over long distances, as well as some means of safely storing and discharging such huge quantities of energy, and currently our understanding of the physics is that it can't happen as a result. Furthermore, consider the problems of having a culture with FTL of that nature: if you can't find a stable wormhole, you're pretty much relegated to permanently destroying a large amount of useful material. It's much much more efficient to simply move things at high fractions of C in realspace. Slower, but far more efficient and cheaper. Likewise, teleportation's largely a no, due to Heisenberg uncertainty and the problems associated with storing the amount of data necessary to reconstruct an item at the sub-atomic level appropriately.
