Hard 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. The term is formed by analogy to the popular distinction between the "hard" (natural) and "soft" (social) sciences, although there are examples generally considered as "hard" science fiction such as Isaac Asimov's Foundation series, built on mathematical sociology. Science fiction critic Gary Westfahl argues that neither term is part of a rigorous taxonomy; instead they are approximate ways of characterizing stories that reviewers and commentators have found useful.
Strange and exotic weapons are a recurring feature in science fiction. In some cases, weapons first introduced in science fiction have been made a reality; other science-fiction weapons remain purely fictional, and are often beyond the realms of known physical possibility.
Speculative and science fiction writers have often addressed the social, political, technological, and biological consequences of pregnancy and reproduction through the exploration of possible futures or alternative realities.
Cleve Cartmill was an American writer of science fiction and fantasy short stories. He is best remembered for what is sometimes referred to as "the Cleve Cartmill affair", when his 1944 story "Deadline" attracted the attention of the FBI by reason of its detailed description of a nuclear weapon similar to that being developed by the highly classified Manhattan Project.
Rubber science is a science fiction term describing a quasi-scientific explanation for an aspect of a science fiction setting. Rubber science explanations are fictional but convincing enough to avoid upsetting the suspension of disbelief. Rubber science is a feature of most genres of science fiction, with the exception of hard science fiction.
The literary genre of science fiction is diverse, and its exact definition remains a contested question among both scholars and devotees. This lack of consensus is reflected in debates about the genre's history, particularly over determining its exact origins. There are two broad camps of thought, one that identifies the genre's roots in early fantastical works such as the Sumerian Epic of Gilgamesh. A second approach argues that science fiction only became possible sometime between the 17th and early 19th centuries, following the scientific revolution and major discoveries in astronomy, physics, and mathematics.
Worldbuilding is the process of constructing an imaginary world or setting, sometimes associated with a fictional universe. Developing the world with coherent qualities such as a history, geography, culture and ecology is a key task for many science fiction or fantasy writers. Worldbuilding often involves the creation of geography, a backstory, flora, fauna, inhabitants, technology and often if writing speculative fiction, different peoples. This may include social customs as well as invented languages for the world.
In science fiction, a time viewer, temporal viewer, or chronoscope is a device that allows another point in time to be observed. The concept has appeared since the late 19th century, constituting a significant yet relatively obscure subgenre of time travel fiction and appearing in various media including literature, cinema, and television. Stories usually explain the technology by referencing cutting-edge science, though sometimes invoking the supernatural instead. Most commonly only the past can be observed, though occasionally time viewers capable of showing the future appear; these devices are sometimes limited in terms of what information about the future can be obtained. Other variations on the concept include being able to listen to the past but not view it.
Mundane science fiction (MSF) is a niche literary movement within science fiction that developed in the early 2000s, with principles codified by the "Mundane Manifesto" in 2004, signed by author Geoff Ryman and "The Clarion West 2004 Class". The movement proposes "mundane science fiction" as its own subgenre of science fiction, typically characterized by its setting on Earth or within the Solar System; a lack of interstellar travel, intergalactic travel or human contact with extraterrestrials; and a believable use of technology and science as it exists at the time the story is written or a plausible extension of existing technology. There is debate over the boundaries of MSF and over which works can be considered canonical. Rudy Rucker has noted MSF's similarities to hard science fiction and Ritch Calvin has pointed out MSF's similarities to cyberpunk. Some commentators have identified science fiction films and television series which embody the MSF ethos of near-future realism.
There have been many attempts at defining science fiction. This is a list of definitions that have been offered by authors, editors, critics and fans over the years since science fiction became a genre. Definitions of related terms such as "science fantasy", "speculative fiction", and "fabulation" are included where they are intended as definitions of aspects of science fiction or because they illuminate related definitions—see e.g. Robert Scholes's definitions of "fabulation" and "structural fabulation" below. Some definitions of sub-types of science fiction are included, too; for example see David Ketterer's definition of "philosophically-oriented science fiction". In addition, some definitions are included that define, for example, a science fiction story, rather than science fiction itself, since these also illuminate an underlying definition of science fiction.
Materials science in science fiction is the study of how materials science is portrayed in works of science fiction. The accuracy of the materials science portrayed spans a wide range – sometimes it is an extrapolation of existing technology, sometimes it is a physically realistic portrayal of a far-out technology, and sometimes it is simply a plot device that looks scientific, but has no basis in science. Examples are:
"Deadline" is a 1944 science fiction short story by American writer Cleve Cartmill, first published in Astounding Science Fiction. The story described the then-secret atomic bomb in some detail. At that time the bomb was still under development and top secret, which prompted a visit by the FBI.
The Mightiest Machine is a science fiction novel by American writer John W. Campbell, Jr. The novel was originally serialized in 5 parts in Astounding Stories magazine from December 1934 to April 1935, and was published in book form in 1947 by The Hadley Publishing Co. in an edition of 1,200 copies. Campbell was a leading figure in the Golden Age of Science Fiction.
Physics of the Impossible: A Scientific Exploration Into the World of Phasers, Force Fields, Teleportation, and Time Travel is a book by theoretical physicist Michio Kaku. Kaku uses discussion of speculative technologies to introduce topics of fundamental physics to the reader.
Fiction is any creative work, chiefly any narrative work, portraying individuals, events, or places that are imaginary or in ways that are imaginary. Fictional portrayals are thus inconsistent with history, fact, or plausibility. In a traditional narrow sense, "fiction" refers to written narratives in prose – often referring specifically to novels, novellas, and short stories. More broadly, however, fiction encompasses imaginary narratives expressed in any medium, including not just writings but also live theatrical performances, films, television programs, radio dramas, comics, role-playing games, and video games. The publishing industry divides fiction into adult fiction, young adult fiction, new adult fiction, and children's fiction.
Lab lit is a loosely defined genre of fiction, distinct from science fiction, that centers on realistic portrayals of scientists and science as a profession.
Soft 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, as opposed to hard science fiction, which explores the "hard" sciences. It can also refer to science fiction which prioritizes human emotions over the scientific accuracy or plausibility of hard science fiction.
Speculative evolution is a subgenre of science fiction and an artistic movement focused on hypothetical scenarios in the evolution of life, and a significant form of fictional biology. It is also known as speculative biology and it is referred to as speculative zoology in regards to hypothetical animals. Works incorporating speculative evolution may have entirely conceptual species that evolve on a planet other than Earth, or they may be an alternate history focused on an alternate evolution of terrestrial life. Speculative evolution is often considered hard science fiction because of its strong connection to and basis in science, particularly biology.
Space travel, or space flight is a classic science-fiction theme that has captivated the public and is almost archetypal for science fiction. Space travel, interplanetary or interstellar, is usually performed in space ships, and spacecraft propulsion in various works ranges from the scientifically plausible to the totally fictitious.
