Laurence van Cott Niven is an American science fiction writer. His best-known works are Ringworld (1970), which received Hugo, Locus, Ditmar, and Nebula awards, and, with Jerry Pournelle, The Mote in God's Eye (1974) and Lucifer's Hammer (1977). The Science Fiction and Fantasy Writers of America named him the 2015 recipient of the Damon Knight Memorial Grand Master Award. His work is primarily hard science fiction, using big science concepts and theoretical physics. It also often includes elements of detective fiction and adventure stories. His fantasy includes the series The Magic Goes Away, rational fantasy dealing with magic as a non-renewable resource.
Known Space is the fictional setting of about a dozen science fiction novels and several collections of short stories written by Larry Niven. It has also become a shared universe in the spin-off Man-Kzin Wars anthologies. The Internet Speculative Fiction Database (ISFDB) catalogs all works set in the fictional universe that includes Known Space under the series name Tales of Known Space, which was the title of a 1975 collection of Niven's short stories. The first-published work in the series, which was Niven's first published piece was "The Coldest Place", in the December 1964 issue of If magazine, edited by Frederik Pohl. This was the first-published work in the 1975 collection.
Ringworld is a 1970 science fiction novel by Larry Niven, set in his Known Space universe and considered a classic of science fiction literature. Ringworld tells the story of Louis Wu and his companions on a mission to the Ringworld, a rotating wheel artificial world, an alien construct in space 186 million miles in diameter. Niven later added three sequel novels and then cowrote, with Edward M. Lerner, four prequels and a final sequel; the five latter novels constitute the Fleet of Worlds series. All the Ringworld novels tie into numerous other books set in Known Space. Ringworld won the Nebula Award in 1970, as well as both the Hugo Award and Locus Award in 1971.
A space habitat is a more advanced form of living quarters than a space station or habitation module, in that it is intended as a permanent settlement or green habitat rather than as a simple way-station or other specialized facility. No space habitat has been constructed yet, but many design concepts, with varying degrees of realism, have come both from engineers and from science-fiction authors.
The Integral Trees is a 1984 science fiction novel by American writer Larry Niven. Like much of Niven's work, the story is heavily influenced by the setting: a gas torus, a ring of air around a neutron star. A sequel, The Smoke Ring, was published in 1987.
A megastructure is a very large artificial object, although the limits of precisely how large vary considerably. Some apply the term to any especially large or tall building. Some sources define a megastructure as an enormous self-supporting artificial construct. The products of megascale engineering or astroengineering are megastructures. The lower bound of megastructural engineering might be considered any structure that has any single dimension 1 megameter (1000 km) in length.
Schismatrix is a science fiction novel by Bruce Sterling, originally published in 1985. The story was Sterling's only novel-length treatment of the Shaper/Mechanist universe. Five short stories preceded the novel and are published together with it in a 1996 edition entitled Schismatrix Plus. Schismatrix was nominated for the Nebula Award for Best Novel in 1985, and the British Science Fiction Award in 1986.
"Neutron Star" is an English language science fiction short story by American writer Larry Niven. It was originally published in the October 1966 issue of Worlds of If. It was later reprinted in the collection of the same name and Crashlander. The story is set in Niven's fictional Known Space universe. It is notable for including a neutron star before their existence was widely known.
A World Out of Time is a science fiction novel by Larry Niven and published in 1976. It is set outside the Known Space universe of many of Niven's stories, but is otherwise fairly representative of his 1970s hard science fiction novels. The main part of the novel was originally serialized in Galaxy magazine as "Children of the State"; another part was originally published as the short story "Rammer". A World Out of Time placed fifth in the annual Locus Poll in 1977.
The Ringworld Engineers is a 1979 science fiction novel by American writer Larry Niven. It is the first sequel to Niven's Ringworld and was nominated for both the Hugo and Locus Awards in 1981.
The Ringworld Throne is a science fiction novel by American writer Larry Niven, first published in 1996. It is the direct sequel to his previous work The Ringworld Engineers (1980). He wrote it as a replacement after being unable to finish his contracted novel The Ghost Ships, the sequel to The Integral Trees and The Smoke Ring.
Fictional depictions of Mercury, the innermost planet of the Solar System, have gone through three distinct phases. Before much was known about the planet, it received scant attention. Later, when it was incorrectly believed that it was tidally locked with the Sun creating a permanent dayside and nightside, stories mainly focused on the conditions of the two sides and the narrow region of permanent twilight between. Since that misconception was dispelled in 1965, the planet has again received less attention from fiction writers, and stories have largely concentrated on the harsh environmental conditions that come from the planet's proximity to the Sun.
This is a list of occurrences of space elevators in fiction. Some depictions were made before the space elevator concept became fully established.
A gas torus is a toroidal cloud of gas or plasma that encircles a planet. In the Solar System, gas tori tend to be produced by the interaction of a satellite's atmosphere with the magnetic field of a planet. The most famous example of this is the Io plasma torus, which is produced by the ionization of roughly 1 ton per second of oxygen and sulfur from the tenuous atmosphere of Jupiter's volcanic moon Io. Before being ionized, these particles are part of a neutral torus, also centered on the orbit of Io. Energetic particle observations also suggest the presence of a neutral torus around the orbit of Jupiter's moon Europa although such a torus would be merged with the outer portions of an Io torus.
World of Ptavvs is a science fiction novel by American writer Larry Niven, first published in 1966 and set in his Known Space universe. It was Niven's first published novel and is based on a 1965 magazine story of the same name.
The planetary systems of stars other than the Sun and the Solar System are a staple element in many works of the science fiction genre.
"The State" is a fictional totalitarian world government in a future history that forms the back-story of three of Larry Niven's novels: A World Out of Time (1976), The Integral Trees (1984), and The Smoke Ring (1987). It is also the setting of two short stories, "Rammer" and "The Kiteman" as well as a stalled fourth novel, The Ghost Ships. After several years in development, Niven announced that The Ghost Ships would never be made, and wrote The Ringworld Throne instead. The novel would have focused on a race of self-aware natural Bussard ramjets birthed in the supernova that created Levoy's Star and were returning to their place of birth to mate. According to Playgrounds of the Mind, Kendy and the kite-fliers from "The Kiteman" would have returned also.
A Bishop Ring is a type of hypothetical rotating space habitat originally proposed in 1997 by Forrest Bishop of the Institute of Atomic-Scale Engineering. The concept is a smaller scale version of the Banks Orbital, which itself is a smaller version of the Niven ring. Like other space habitat designs, the Bishop Ring would spin to produce artificial gravity by way of centrifugal force. The design differs from the classical designs produced in the 1970s by Gerard K. O'Neill and NASA in that it would use carbon nanotubes instead of steel, allowing the habitat to be built much larger. In the original proposal, the habitat would be approximately 1,000 km (620 mi) in radius and 500 km (310 mi) in width, containing 3 million square kilometers of living space, comparable to the area of Argentina or India.
The Halo Array is a group of fictional megastructures and superweapons in the Halo science-fiction franchise, consisting of ringworlds known as Halos built by a structure known as the Ark. They are referred to as "Installations" by their artificial intelligence caretakers, and were created by an ancient race known as the Forerunners. The series' alien antagonists, the Covenant, refer to the Halos as the "Sacred Rings", believing them to form part of a greater religious prophecy known as "The Great Journey". In the games' stories, the Forerunners built the Halo Array to contain and study the Flood, an infectious alien parasite. The rings act together as a weapon of last resort; when fired, they kill all sentient life in the galaxy capable of falling prey to the Flood, thereby starving the parasite of its food. The battle to prevent their activation forms the crux of the plot progression for the first Halo trilogy of games.
