[QUOTE="DarkKestral, post: 3121002, member: 40100"] Strictly, 'hard sf' denotes only that technologies presented in the material are all possible within current understanding of physics, biology, and chemistry. Setting and content otherwise don't matter. In short, for the most part, d20 Future does do Hard Science. It's just mostly concentrated at PL 5-PL 7. Nanobots? unlikely within a short timeframe, but doable. FTL? not really, as it requires wormhole technology which appears to be impossible, because to build wormholes, you would have to annihilate entire star systems in one shot each time you wanted to open a wormhole large enough for a ship to pass through for the necessary length of time, as far as we know... and even then it might not be possible. Otherwise, you're out of luck. Oddly, ansibles might not be impossible, but would be hideously expensive, as you would need to maintain quantum entanglement. (There are other ways, but they would be even more hideously expensive, and very very chancy.) However, other than cold fusion, teleportation, FTL, interstellar-distance instant communications, and gravity control, there's really not many things that are limited in a hard science world, as a combination of nanotech, cryogenics, and commercial fusion could make interstellar travel fairly common, and we've already got the basic technologies required for implementation, but we have yet to advance them to the level at which high PL societies would have them.
