Science fiction

Science fiction (NF) is a genre in literature, cinema and other arts, one of the varieties of fiction. Science fiction is based on fantastic assumptions (fiction, speculation) in the field of science, including both the exact and natural sciences and the humanities.

Science fiction describes fictional technologies and scientific discoveries, contacts with nonhuman reason, possible future or alternative course of history, and the impact of these assumptions on human society and personality. Action science fiction often occurs in the future, which is related to this genre with futurology.
