Science fictionScience fiction (sometimes shortened to SF or sci-fi) is a genre of speculative fiction, which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, and extraterrestrial life. Science fiction can trace its roots to ancient mythology. It is related to fantasy, horror, and superhero fiction and contains many subgenres. Its exact definition has long been disputed among authors, critics, scholars, and readers.
FantasyFantasy is a genre of speculative fiction involving magical elements, typically set in a fictional universe and usually inspired by mythology or folklore. The term "fantasy" can also be used to describe a "work of this genre", usually literary. Its roots are in oral traditions, which became fantasy literature and drama. From the twentieth century, it has expanded further into various media, including film, television, graphic novels, manga, animations and video games.
Fictional universeA fictional universe is the internally consistent fictional setting used in a narrative work or work of art, most commonly associated with works of fantasy and science fiction. Fictional universes appear in novels, comics, films, television shows, video games, art, and other creative works. A fictional universe may be an alternative version of the real world, differing only in the particulars of the story.
Media franchiseA media franchise, also known as a multimedia franchise, is a collection of related media in which several derivative works have been produced from an original creative work of fiction, such as a film, a work of literature, a television program or a video game. Bob Iger, chief executive of the Walt Disney Company, defined the word franchise as "something that creates value across multiple businesses and across multiple territories over a long period of time". A media franchise often consists of cross-marketing across more than one medium.
Fan fictionFan fiction or fanfiction (also abbreviated to fan fic, fanfic, fic or FF) is fictional writing written in an amateur capacity by fans, unauthorized by, but based on an existing work of fiction. The author uses copyrighted characters, settings, or other intellectual properties from the original creator(s) as a basis for their writing. Fan fiction ranges from a couple of sentences to an entire novel, and fans can retain the creator's characters and settings and/or add their own. It is a form of fan labor.
Hard science fictionHard science fiction is a category of science fiction characterized by concern for scientific accuracy and logic. The term was first used in print in 1957 by P. Schuyler Miller in a review of John W. Campbell's Islands of Space in the November issue of Astounding Science Fiction. The complementary term soft science fiction, formed by analogy to hard science fiction, first appeared in the late 1970s.
TeleportationTeleportation is the hypothetical transfer of matter or energy from one point to another without traversing the physical space between them. It is a common subject in science fiction literature and in other popular culture. Teleportation is often paired with time travel, being that the travelling between the two points takes an unknown period of time, sometimes being immediate. An apport is a similar phenomenon featured in parapsychology and spiritualism. There is no known physical mechanism that would allow for teleportation.
FuturismFuturism (Futurismo, futuˈrizmo) was an artistic and social movement that originated in Italy, and to a lesser extent in other countries, in the early 20th century. It emphasized dynamism, speed, technology, youth, violence, and objects such as the car, the airplane, and the industrial city. Its key figures included the Italians Filippo Tommaso Marinetti, Umberto Boccioni, Carlo Carrà, Fortunato Depero, Gino Severini, Giacomo Balla, and Luigi Russolo.
Soft science fictionSoft science fiction, or soft SF, is a category of science fiction with two different definitions, defined in contrast to hard science fiction. It can refer to science fiction that explores the "soft" sciences (e.g. psychology, political science, anthropology), as opposed to hard science fiction, which explores the "hard" sciences (e.g. physics, astronomy, biology). It can also refer to science fiction which prioritizes human emotions over the scientific accuracy or plausibility of hard science fiction.
