"Science fiction (sometimes called Sci-Fi or simply SF) is a genre of speculative fiction that has been called the "literature of ideas". It typically deals with imaginative and futuristic concepts such as advanced science and technology, time travel, parallel universes, fictional worlds, space exploration, and extraterrestrial life. It often explores the potential consequences of scientific innovations.
Science fiction, whose roots go back to ancient times, is related to fantasy, horror, and superhero fiction, and contains many subgenres. However its exact definition has long been disputed among authors, critics, and scholars." - (en.wikipedia.org 22.09.2019)
