| − | '''Science fiction''' is a form of [[literature]] that includes some form of speculation as to a possible [[science|scientific]] or [[technology|technological]] discovery, invention, or project that has not yet come to pass at the time of writing.

A speculative project may, but does not necessarily, violate the laws of nature as most scientists understand them. A speculative discovery may be either a new scientific law, or a revision of an existing law, or of an object, substance, environment, or even an entire [[civilization]] previously unknown to man. | + | '''Science fiction''' is a form of [[literature]] and movies that often includes speculation as to a possible [[science|scientific]] or [[technology|technological]] discovery, invention, or project that has not yet come to pass, or something related to an alien invasion or space travel.
