[QUOTE="fredramsey, post: 1883453, member: 20274"] Wow, this is a can of worms that, as usual, has no place to go but down... ;) Here are two definitions of "True" SF, each of which has been argued before: 1. You must only extrapolate from what we know now. This definition is the most hardcore, and is followed very rarely. 2. You are allowed one and only one "breakthrough", such as AI or FTL travel. This one is used more often for so-called "hard" SF. This is an argument that can go on and on. While I agree, for example, that Star Wars is not hard SF, since its release, we have sent spacecraft into the void with Ion engines, and there are always theoretical physicists who postulate about the existence of hyperspace. The biggest non-sf element in Star Wars, besides the Force, is the motion and sound of the spacecraft. One of the best almost pure SF films there has ever been, IMHO, is 2010. Have fun with this one; it ain't gonna be solved here. :uhoh: [/QUOTE]
