Changes

'''Science fiction''' is a form of [[literature]] that includes some form of speculation as to a possible [[science|scientific]] discovery, invention, or project that has not yet come to pass at the time of writing. Alternativey, it may explore the implications of a kind of a sentient being, society or civilization that is significantly different than any with which we are familiar. Such a project is usually, but not always, intended as a metaphor for an unsettling social change, or a vehicle to introduce a discussion of such change. 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.
