Science Fiction: Difference between revisions

'''[http://en.wikipedia.org/wiki/Science_fiction Science fiction]''' (sometimes hyphenated as '''science-fiction''' or abbreviated as '''SF''' or '''sci-fi''') is imaginative writing about the consequences of advancements in science and technology. Science fiction differs from [[fantasy]] in that whatever happens in science fiction is expected to be possible within the laws of nature as they are understood today or as they might be understood in the future. What happens in fantasy is assumed to be impossible under any circumstances ([http://en.wikipedia.org/wiki/Clarke%27s_Three_Laws Clarke's Third Law] aside). Speculations about exotic discoveries like teleportation, faster-than-light spacecraft, and time travel are included, as many elements of the modern world (e.g., computers, spacecraft, vaccines, nuclear power) were also once thought impossible.
