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" is difficult to define precisely, as it includes a wide range of concepts and themes.
James Blish wrote: "Wells used the term originally to cover what we would today call "hard" science fiction, in which a conscientious attempt to be faithful to already known facts (as of the date of writing) was the substrate on which the story was to be built, and if the story was also to contain a miracle, it ought at least not to contain a whole arsenal of them."
Isaac Asimov said: "Science fiction can be defined as that branch of literature which deals with the reaction of human beings to changes in science and technology." According to Robert A. Heinlein, "A handy short definition of almost all science fiction might read: realistic speculation about possible future events, based solidly on adequate knowledge of the real world, past and present, and on a thorough understanding of the nature and significance of the scientific method."
Tom Shippey compared George Orwell's Coming Up for Air (1939) with Frederick Pohl and C. M. Kornbluth's The Space Merchants (1952), and concluded that the basic building block and distinguishing feature of a science fiction novel is the presence of the novum, a term Darko Suvin adapted from Ernst Bloch and defined as "a discrete piece of information recognizable as not-true, but also as not-unlike-true, not-flatly- (and in the current state of knowledge) impossible."
Lester del Rey wrote, "Even the devoted aficionado or fan—has a hard time trying to explain what science fiction is," and the lack of a "full satisfactory definition" is because "there are no easily delineated limits to science fiction." Author and editor Damon Knight summed up the difficulty, saying "science fiction is what we point to when we say it." Mark C. Glassey described science fiction as U.S. Supreme Court Justice Potter Stewart described pornography: "I know it when I see it."
Science fiction had its beginnings in ancient times when the line between myth and fact were blurred. Written in the 2nd century CE by the satirist Lucian, A True Story contains many themes and tropes characteristic of modern science fiction, including travel to other worlds, extraterrestrial lifeforms, interplanetary warfare, and artificial life. Some consider it the first science-fiction novel.The%20New%20Encyclopedia%20of%20Science%20F]]  Some of the stories fromThe Tale of the Bamboo CutterIbn al-Nafis's  also contain elements of science fiction.
Products of the Scientific Revolution and the Age of Enlightenment, Johannes Kepler's Somnium (1634), Francis Bacon's New Atlantis (1627), Cyrano de Bergerac's Comical History of the States and Empires of the Moon (1657) and The States and Empires of the Sun (1662), Margaret Cavendish's "The Blazing World" (1666), Jonathan Swift's Gulliver's Travels (1726), Ludvig Holberg's Nicolai Klimii Iter Subterraneum (1741) and Voltaire's Micromégas (1752) are regarded as some of the first true science-fantasy works. Isaac Asimov and Carl Sagan considered Somnium the first science-fiction story; it depicts a journey to the Moon and how the Earth's motion is seen from there.
Following the 18th-century development of the novel as a literary form, Mary Shelley's Frankenstein (1818) and The Last Man (1826) helped define the form of the science-fiction novel. Brian Aldiss has argued that Frankenstein was the first work of science fiction. Edgar Allan Poe wrote several stories considered to be science fiction, including "The Unparalleled Adventure of One Hans Pfaall" (1835) which featured a trip to the Moon. Jules Verne was noted for his attention to detail and scientific accuracy, especially in Twenty Thousand Leagues Under the Sea (1870). In 1887, the novel El anacronópete by Spanish author Enrique Gaspar y Rimbau introduced the first time machine.

By 'scientifiction' I mean the Jules Verne, H. G. Wells and Edgar Allan Poe type of story—a charming romance intermingled with scientific fact and prophetic vision...
Not only do these amazing tales make tremendously interesting reading—they are always instructive.
They supply knowledge... in a very palatable form...
New adventures pictured for us in the scientifiction of today are not at all impossible of realization tomorrow...
Many great science stories destined to be of historical interest are still to be written...
In 1928, E. E. "Doc" Smith's first published work, The Skylark of Space, written in collaboration with Lee Hawkins Garby, appeared in Amazing Stories. It is often called the first great space opera. The same year, Philip Francis Nowlan's original Buck Rogers story, Armageddon 2419, also appeared in Amazing Stories. This was followed by a Buck Rogers comic strip, the first serious science-fiction comic.
In 1937, John W. Campbell became editor of Astounding Science Fiction, an event which is sometimes considered the beginning of the Golden Age of Science Fiction, which is characterized by stories celebrating scientific achievement and progress. In 1942, Isaac Asimov started his Foundation series, which chronicles the rise and fall of galactic empires and introduced psychohistory. The "Golden Age" is often said to have ended in 1946, but sometimes the late 1940s and the 1950s are included.
George Orwell's Nineteen Eighty-Four, published in 1949, is an important work of dystopian science fiction. Theodore Sturgeon's More Than Human (1953) explored possible future human evolution. In 1957, Andromeda: A Space-Age Tale by the Russian writer and paleontologist Ivan Yefremov presented a view of a future interstellar communist civilization and is considered one of the most important Soviet science fiction novels.
In 1959, Robert A. Heinlein's Starship Troopers marked a departure from his earlier juvenile stories and novels. It is one of the first and most influential examples of military science fiction, and introduced the concept of powered armor exoskeletons. The German space opera series Perry Rhodan, written by various authors, started in 1961 with an account of the first Moon landing and has since expanded in space to multiple universes, and in time by billions of years. It has become the most popular science fiction book series of all time.
In the 1960s and 1970s, New Wave science fiction was known for its embrace of a high degree of experimentation, both in form and in content, and a highbrow and self-consciously "literary" or "artistic" sensibility.The%20Generation%20Starship%20in]]n 1961, Solaris Stanisław Lem Poland dealt with the theme of human limitations as its characters attempted to study a seemingly intelligent ocean on a newly discovered planet.%2C%20fourth%20edition%20%281]]*965's
In 1968, Philip K. Dick's Do Androids Dream of Electric Sheep?, was published. It is the literary source of the Blade Runner movie franchise. 1969's The Left Hand of Darkness by Ursula K. Le Guin was set on a planet in which the inhabitants have no fixed gender. It is one of the most influential examples of social science fiction, feminist science fiction, and anthropological science fiction.
In 1976, C. J. Cherryh published Gate of Ivrel and Brothers of Earth, which began her Alliance-Union universe future history series. In 1979, Science Fiction World began publication in the People's Republic of China. It dominates the Chinese science fiction magazine market, at one time claiming a circulation of 300,000 copies per issue and an estimated 3-5 readers per copy (giving it a total estimated readership of at least 1 million), making it the world's most popular science fiction periodical.
In 1984, William Gibson's first novel, Neuromancer, helped popularize cyberpunk and the word "cyberspace," a term he originally coined in his 1982 short story Burning Chrome. In 1986, Shards of Honor by Lois McMaster Bujold began her Vorkosigan Saga. 1992's Snow Crash by Neal Stephenson predicted immense social upheaval due to the information revolution. In 2007, Liu Cixin's novel, The Three-Body Problem, was published in China. It was translated into English by Ken Liu and published by Tor Books in 2014, and won the 2015 Hugo Award for Best Novel, making Liu the first Asian writer to win the award.
Emerging themes in late 20th and early 21st century science fiction include environmental issues, the implications of the Internet and the expanding information universe, questions about biotechnology, nanotechnology, and post-scarcity societies. Recent trends and subgenres include steampunk, biopunk, and mundane science fiction.
The first, or at least one of the first, recorded science fiction film is 1902's A Trip to the Moon, directed by French filmmaker Georges Méliès. It was profoundly influential on later filmmakers, bringing a different kind of creativity and fantasy to the cinematic medium. In addition, Méliès's innovative editing and special effects techniques were widely imitated and became important elements of the medium.
1968's 2001: A Space Odyssey, directed by Stanley Kubrick and based on the work of Arthur C. Clarke, rose above the mostly B-movie offerings up to that time, both in scope and quality, and greatly influenced later science fiction films. That same year, Planet of the Apes (the original), directed by Franklin J. Schaffner and based on the 1963 French novel La Planète des Singes by Pierre Boulle, was released to popular and critical acclaim, due in large part to its vivid depiction of a post-apocalyptic world in which intelligent apes dominate humans.
In 1977, George Lucas began the Star Wars film series*film series]]th the film now identified as " Star Wars: Episode IV – A New Hope often called a space opera, went on to become a worldwide popular culture phenomenon, and the second-highest-grossing film series of all time.
Since the 1980s, science fiction films, along with fantasy, horror, and superhero films, have dominated Hollywood's big-budget productions. Science fiction films often "cross-over" with other genres, including animation WALL-E - 2008, Big Hero 6 - 2014), gangster (Sky Racket - 1937), Western (Serenity - 2005), comedy (Spaceballs -1987, Galaxy Quest - 1999), war (Enemy Mine - 1985), action (Edge of Tomorrow - 2014, The Matrix - 1999), adventure (Jupiter Ascending - 2015, Interstellar - 2014), sports (Rollerball - 1975), mystery (Minority Report - 2002), thriller (Ex Machina - 2014), horror (Alien - 1979), film noir (Blade Runner - 1982), superhero (Marvel Cinematic Universe - 2008-), drama (Arrival - 2016, A.I.: Artificial Intelligence -2001), and romantic comedy (Eternal Sunshine of the Spotless Mind - 2004).
The first known science fiction television program was a thirty-five-minute adapted excerpt of the play RUR, written by the Czech playwright Karel Čapek, broadcast live from the BBC's Alexandra Palace studios on 11 February 1938. The first popular science fiction program on American television was the children's adventure serial Captain Video and His Video Rangers, which ran from June 1949 to April 1955.
The Twilight Zone (the original series), produced and narrated by Rod Serling, who also wrote or co-wrote most of the episodes, ran from 1959 to 1964. It featured fantasy, suspense, and horror as well as science fiction, with each episode being a complete story. Critics have ranked it as one of the best TV programs of any genre.
The animated series The Jetsons, while intended as comedy and only running for one season (1962–1963), predicted many inventions now in common use: flat-screen televisions, newspapers on a computer-like screen, computer viruses, video chat, tanning beds, home treadmills, and more. In 1963, the time travel-themed Doctor Who premiered on BBC Television. The original series ran until 1989 and was revived in 2005. It has been extremely popular worldwide and has greatly influenced later TV science fiction. Other programs in the 1960s included The Outer Limits (1963-1965), Lost in Space (1965-1968), and The Prisoner (1967).
Star Trek (the original series), created by Gene Roddenberry, premiered in 1966 on NBC Television and ran for three seasons. It combined elements of space opera and Space Western. Only mildly successful at first, the series gained popularity through syndication and extraordinary fan interest. It became a very popular and influential franchise with many films and television shows, novels, and other works and products.]]  Star Trek: The Next Generation 1987-1994) led to four additional Star Trek shows (Deep Space 9 (1993-1999), Voyager (1995-2001), Enterprise (2001-2005), and Discovery (2017-present))--with more in some form of development.
The miniseries V premiered in 1983 on NBC. It depicted an attempted takeover of Earth by reptilian aliens. Red Dwarf, a comic science fiction series aired on BBC Two between 1988 and 1999, and on Dave since 2009. The X-Files, which featured UFOs and conspiracy theories, was created by Chris Carter and broadcast by Fox Broadcasting Company from 1993 to 2002, and again from 2016-2018. Stargate, a film about ancient astronauts and interstellar teleportation, was released in 1994. Stargate SG-1 premiered in 1997 and ran for 10 seasons (1997-2007). Spin-off series included Stargate Infinity (2002-2003), Stargate Atlantis (2004-2009), and Stargate Universe (2009-2011). Other 1990s series included Quantum Leap (1989-1993) and Babylon 5 (1994-1999).
Science fiction's great rise in popularity during the first half of the 20th century was closely tied to the popular respect paid to science at that time, as well as the rapid pace of technological innovation and new inventions. Science fiction has often predicted scientific and technological progress. Some works predict that new inventions and progress will tend to improve life and society, for instance the stories of Arthur C. Clarke and Star Trek. Others, such as H.G. Wells's The Time Machine and Aldous Huxley's Brave New World, warn about possible negative consequences.
In 2001 the National Science Foundation conducted a survey on "Public Attitudes and Public Understanding: Science Fiction and Pseudoscience." It found that people who read or prefer science fiction may think about or relate to science differently than other people. They also tend to support the space program and the idea of contacting extraterrestrial civilizations. Carl Sagan wrote: "Many scientists deeply involved in the exploration of the solar system (myself among them) were first turned in that direction by science fiction."
Brian Aldiss described science fiction as "cultural wallpaper." Evidence for this widespread influence can be found in trends for writers to employ science fiction as a tool for advocacy and generating cultural insights, as well as for educators when teaching across a range of academic disciplines not limited to the natural sciences. Scholar and science fiction critic George Edgar Slusser said that science fiction "is the one real international literary form we have today, and as such has branched out to visual media, interactive media and on to whatever new media the world will invent in the 21st century. Crossover issues between the sciences and the humanities are crucial for the century to come."
As protest literature
Science fiction has sometimes been used as a means of social protest. George Orwell's Nineteen Eighty-Four is often invoked in protests against governments and leaders who are seen as totalitarian. James Cameron's 2009 film Avatar was intended as a protest against imperialism, and specifically the European colonization of the Americas. Its images have been used by, among others, Palestinians in their protest against Israel.
Robots, artificial humans, human clones, intelligent computers, and their possible conflicts with human society have all been major themes of science fiction since, at least, the publication of Shelly's Frankenstein. Some critics have seen this as reflecting authors’ concerns over the social alienation seen in modern society.
Feminist science fiction poses questions about social issues such as how society constructs gender roles, the role reproduction plays in defining gender, and the inequitable political or personal power of one gender over others. Some works have illustrated these themes using utopias to explore a society in which gender differences or gender power imbalances do not exist, or dystopias to explore worlds in which gender inequalities are intensified, thus asserting a need for feminist work to continue.
Climate fiction, or "cli-fi," deals with issues concerning climate change and global warming. University courses on literature and environmental issues may include climate change fiction in their syllabi, and it is often discussed by other media outside of science fiction fandom.
Sense of wonder
Science fiction is often said to generate a "sense of wonder." Science fiction editor and critic David Hartwell wrote: "Science fiction’s appeal lies in combination of the rational, the believable, with the miraculous. It is an appeal to the sense of wonder." Carl Sagan said: "One of the great benefits of science fiction is that it can convey bits and pieces, hints and phrases, of knowledge unknown or inaccessible to the reader... works you ponder over as the water is running out of the bathtub or as you walk through the woods in an early winter snowfall."
In 1967, Isaac Asimov commented on the changes then occurring in the science fiction community: "And because today’s real life so resembles day-before-yesterday’s fantasy, the old-time fans are restless.
Deep within, whether they admit it or not, is a feeling of disappointment and even outrage that the outer world has invaded their private domain.
They feel the loss of a 'sense of wonder' because what was once truly confined to 'wonder' has now become prosaic and mundane."
Science fiction studies
The study of science fiction, or science fiction studies, is the critical assessment, interpretation, and discussion of science fiction literature, film, TV shows, new media, fandom, and fan fiction. Science fiction scholars study science fiction to better understand it and its relationship to science, technology, politics, other genres, and culture-at-large. Science fiction studies began around the turn of the 20th century, but it was not until later that science fiction studies solidified as a discipline with the publication of the academic journals Extrapolation (1959), Foundation: The International Review of Science Fiction (1972), and Science Fiction Studies (1973), and the establishment of the oldest organizations devoted to the study of science fiction in 1970, the Science Fiction Research Association and the Science Fiction Foundation. The field has grown considerably since the 1970s with the establishment of more journals, organizations, and conferences, as well as science fiction degree-granting programs such as those offered by the University of Liverpool and the University of Kansas.
Science fiction has historically been sub-divided between hard science fiction and soft science fiction–with the division centering on the feasibility of the science central to the story. However, this distinction has come under increasing scrutiny in the 21st century. Some authors, such as Tade Thompson and Jeff VanderMeer, have pointed out that stories that focus explicitly on physics, astronomy, mathematics, and engineering tend to be considered "hard" science fiction, while stories that focus on botany, mycology, zoology, and the social sciences tend to be categorized as "soft," regardless of the relative rigor of the science.
Max Gladstone defined "hard" science fiction as stories "where the math works," but pointed out that this ends up with stories that often seem "weirdly dated," as scientific paradigms shift over time. Michael Swanwick dismissed the traditional definition of "hard" SF altogether, instead saying that it was defined by characters striving to solve problems "in the right way–with determination, a touch of stoicism, and the consciousness that the universe is not on his or her side."
Ursula K. Leguin also criticized the more traditional view on the difference between "hard" and "soft" SF: "The 'hard' science fiction writers dismiss everything except, well, physics, astronomy, and maybe chemistry. Biology, sociology, anthropology—that's not science to them, that's soft stuff. They're not that interested in what human beings do, really. But I am. I draw on the social sciences a great deal."
As serious literature
Respected authors of main-stream literature have written science fiction. Mary Shelley wrote a number of science fiction novels including Frankenstein; or, The Modern Prometheus (1818), and is considered a major writer of the Romantic Age. Aldous Huxley's Brave New World (1932) is often listed as one of England's most important novels, both for its criticism of modern culture and its prediction of future trends including reproductive technology and social engineering. Kurt Vonnegut was a highly respected American author whose works contain science fiction premises or themes. Other science fiction authors whose works are widely considered to be "serious" literature include Ray Bradbury (including, especially, Fahrenheit 451 (1953) and The Martian Chronicles (1951)), Arthur C. Clarke (especially for Childhood's End), and Paul Myron Anthony Linebarger, writing under the name Cordwainer Smith.
In her much reprinted essay "Science Fiction and Mrs Brown," American author Ursula K. Le Guin first asked: "Can a science fiction writer write a novel?"; and then answered: "I believe that all novels,... deal with character, and that it is to express character–not to preach doctrines, sing songs, or celebrate the glories of the British Empire, that the form of the novel, so clumsy, verbose, and undramatic, so rich, elastic, and alive, has been evolved.... The great novelists have brought us to see whatever they wish us to see through some character. Otherwise they would not be novelists, but poets, historians, or pamphleteers."
Orson Scott Card, best known for his 1985 science fiction novel Ender's Game and also an author of non-SF fiction, has postulated that in science fiction the message and intellectual significance of the work is contained within the story itself and, therefore, there need not be stylistic gimmicks or literary games.
Science fiction author and physicist Gregory Benford has stated: "SF is perhaps the defining genre of the twentieth century, although its conquering armies are still camped outside the Rome of the literary citadels." Jonathan Lethem, in an essay published in the Village Voice entitled "Close Encounters: The Squandered Promise of Science Fiction," suggested that the point in 1973 when Thomas Pynchon's Gravity's Rainbow was nominated for the Nebula Award and was passed over in favor of Arthur C. Clarke's Rendezvous with Rama, stands as "a hidden tombstone marking the death of the hope that SF was about to merge with the mainstream."
David Barnett has pointed out that there are books such as The Road (2006) by Cormac McCarthy, Cloud Atlas (2004) by David Mitchell, The Gone-Away World (2008) by Nick Harkaway, The Stone Gods (2007) by Jeanette Winterson, and Oryx and Crake (2003) by Margaret Atwood, which use recognizable science fiction tropes, but whose authors and publishers do not market them as science fiction. Doris Lessing, who was later awarded the Nobel Prize in literature, wrote a series of five SF novels, Canopus in Argos: Archives (1979-1983), which depict the efforts of more advanced species and civilizations to influence those less advanced, including humans on Earth.
Science fiction is being written, and has been written, by diverse authors from around the world. According to 2013 statistics by the science fiction publisher Tor Books, men outnumber women by 78% to 22% among submissions to the publisher. A controversy about voting slates in the 2015 Hugo Awards highlighted tensions in the science fiction community between a trend of increasingly diverse works and authors being honored by awards, and reaction by groups of authors and fans who preferred what they considered more "traditional" science fiction.
Among the most respected and well-known awards for science fiction are the Hugo Award for literature, presented by the World Science Fiction Society at Worldcon, and voted on by fans; the Nebula Award for literature, presented by the Science Fiction and Fantasy Writers of America, and voted on by the community of authors; the John W. Campbell Memorial Award for Best Science Fiction Novel, presented by a jury of writers; and the Theodore Sturgeon Memorial Award for short fiction, presented by a jury. One notable award for science fiction films and TV programs is the Saturn Award, which is presented annually by The Academy of Science Fiction, Fantasy, and Horror Films.
There are other national awards, like Canada's Prix Aurora Awards, regional awards, like the Endeavour Award presented at Orycon for works from the U.S. Pacific Northwest, and special interest or subgenre awards such as the Chesley Award for art, presented by the Association of Science Fiction & Fantasy Artists, or the World Fantasy Award for fantasy. Magazines may organize reader polls, notably the Locus Award.
Conventions, clubs, and organizations
Conventions (in fandom, often shortened as "cons," such as "comic-con") are held in cities around the world, catering to a local, regional, national, or international membership. General-interest conventions cover all aspects of science fiction, while others focus on a particular interest like media fandom, filking, and so on. Most science fiction conventions are organized by volunteers in non-profit groups, though most media-oriented events are organized by commercial promoters. The convention's activities are called the program, which may include panel discussions, readings, autograph sessions, costume masquerades, and other events. Additional activities occur throughout the convention that are not part of the program. These commonly include a dealer's room, art show, and hospitality lounge (or "con suites").
Conventions may host award ceremonies.
For instance, Worldcon presents the Hugo Awards each year. SF societies, referred to as "clubs" except in formal contexts, form a year-round base of activities for science fiction fans. They may be associated with an ongoing science fiction convention, or have regular club meetings, or both. Long-established groups like the New England Science Fiction Association and the Los Angeles Science Fantasy Society have clubhouses for meetings and storage of convention supplies and research materials. The Science Fiction and Fantasy Writers of America (SFWA) was founded by Damon Knight in 1965 as a non-profit organization to serve the community of professional science fiction authors.
Fandom and fanzines
Science fiction fandom is the "community of the literature of ideas[,]... the culture in which new ideas emerge and grow before being released into society at large." Members of this community ("fans"), as discussed above, are often in contact with each other at conventions or clubs, through print or online fanzines, or on the Internet using websites, mailing lists, and other resources. SF fandom emerged from the letters column in Amazing Stories magazine: soon fans began writing letters to each other, and then grouping their comments together in informal publications that became known as fanzines. Once they were in regular contact, fans wanted to meet each other, and they organized local clubs. In the 1930s, the first science fiction conventions gathered fans from a wider area.
The earliest organized online fandom was the SF Lovers Community, originally a mailing list in the late 1970s with a text archive file that was updated regularly. In the 1980s, Usenet groups greatly expanded the circle of fans online. In the 1990s, the development of the World-Wide Web exploded the community of online fandom by orders of magnitude, with thousands and then millions of websites devoted to science fiction and related genres for all media. Most such sites are relatively small, ephemeral, and/or narrowly focused, though sites like SF Site and SFcrowsnest offer a broad range of references and reviews.
The first science fiction fanzine, The Comet, was published in 1930 by the Science Correspondence Club in Chicago, Illionois. Fanzine printing methods have changed over the decades, from the hectograph, the mimeograph, and the ditto machine, to modern photocopying. Distribution volumes rarely justify the cost of commercial printing. Contemporary fanzines are largely printed on computer printers or at local copy shops, or they may only be sent as email (termed "Ezines") or otherwise made available online (termed "webzines"). One of the best known fanzines today is Ansible, edited by David Langford, winner of numerous Hugo awards. Other notable fanzines to win one or more Hugo awards include File 770, Mimosa, and Plokta. Artists working for fanzines have frequently risen to prominence in the field, including Brad W. Foster, Teddy Harvia, and Joe Mayhew; the Hugos include a category for Best Fan Artists.
Science fiction elements can include, among others:
Temporal settings in the future, or in alternative histories.
Spatial settings or scenes in outer space, on other worlds, in subterranean earth, or in parallel universes.
Undiscovered scientific possibilities such as teleportation, time travel, and faster-than-light travel or communication.
New and different political and social systems and situations, including Utopian, dystopian, post-apocalyptic, or post-scarcity.
Future history and evolution of humans on Earth or on other planets.
Paranormal abilities such as mind control, telepathy, and telekinesis.

Forrest J Ackerman is credited with first using the term "Sci-Fi" (analogous to the then-trendy "hi-fi") in 1954. As science fiction entered popular culture, writers and fans active in the field came to associate the term with low-budget, low-tech "B-movies," and with low-quality pulp science fiction. By the 1970s, critics within the field, such as Damon Knight and Terry Carr, were using "sci fi" to distinguish hack-work from serious science fiction. Peter Nicholls writes that "SF" (or "sf") is "the preferred abbreviation within the community of sf writers and readers." Robert Heinlein found even "science fiction" insufficient for certain types of works in this genre, and suggested the term speculative fiction to be used instead for those that are more "serious" or "thoughtful."
