I know it looks a stupid question, but please think on a little.
Classic Hard Science Fiction usually depicts something that is just out of our knowledge as a species, but is also within our comfortable scientific grasp. Thus we have the likes of Arthur C Clarkes 'Space Odyssey 2001' or Ben Bova's 'Mars'.
Unfortunately both stories are well within our collective ability to achieve, it is merely politics that prevents them becoming a fact of life. So can they still be described as Science Fiction?
Another is Crichtons 'Jurrasic Park', it used a scientific theory that had not been proven when he wrote it, yet it was never classed as Science Fiction at all!
At the other end of the scale we have Fantasy Science Fiction. These can only be described as possible if the physical rules of science, as we understand them, do a quadruple somersault up their own vertex. Doc Smiths 'Lensmen Series' or even dear old Star Trek.
In the midst are a whole raft of others:
Jules Verne for instance is now often described as not being a Science Fiction writer. Much of the science that was available at the time of writing having been officially poo-poohed. Yet HG Wells has managed to hang on to the Science Fiction crown despite the same disproving by science and subsequent events.
Is Science Fiction classification merely based on the fact that there are aliens from a different world, or at least off of this one?
