Imagine... That's what the literature we know as science fiction or sci-fi can bring into your life.

SF, as it sometimes is called, is a broad category of fiction that generally speculates on past, present and future science and technology. Science fiction has been said to be an alternative literature of ideas.

Science fiction is related to, but not the same as, the fantasy and horror genres. It's unlike fantasy the imaginary elements in sci-fi are largely possible within scientifically established or scientifically postulated laws of nature, even as some elements of a story might still be pure imaginative speculation. SF is writing that is entertaining and rational about alternate possibilities in settings that are contrary to known reality.

Science fiction is enjoyed in numerous formats including books, films, television, theater, video games, artworks and other media: Science fiction artworks: Science fiction movies:
