Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas." It usually avoids the supernatural, and unlike the related genre of fantasy, historically science fiction stories were intended to have a grounding in science-based fact or theory at the time the story was created, but this connection is now limited to hard science fiction.
