Literary fantasies based on real or imagined scientific developments

Science fiction (often shortened to Sci-Fi or SF) is a genre of speculative fiction, typically dealing with imaginative concepts such as advanced science and technology, spaceflight, time travel and extraterrestrial life. Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas".

However, ... it rules out the use of anything as material which violates established scientific fact ...'"
