"Take a Match" is a science fiction short story by American writer Isaac Asimov. It was first published in Robert Silverberg's 1972 anthology New Dimensions II and reprinted in the 1975 Asimov collection Buy Jupiter and Other Stories .
An interstellar spaceship is stranded between the stars, but out of reach of the interstellar gases that the drive requires as fuel (the drive technology is not fully explained but is possibly similar to a Bussard Ramjet). It is surrounded by clouds that contain that required fuel, but with excessive quantities of impurities that can't be filtered out.
Anton Viluekis, the Fusionist, a highly sensitive (and eccentric) individual who is in charge of the ship's power, is unwilling to try any alternative methods of gathering fuel, as failure will reflect badly on his reputation. The crew cannot persuade him otherwise.
Louis Martand, a schoolteacher travelling as a passenger, suspects what the trouble is and realises, from his experience of teaching children, that there is an alternative; that of utilising the 'primitive' technology of chemical combustion. He manages to convey his idea via Cheryl Winter, a pretty female passenger, to the fusionist, who successfully tries it.
The teacher is confined to his quarters by the ship's captain, somewhat apologetically, and warned that he will receive no credit; it must be believed that the fusionist was responsible for the success.
Interstellar travel is the hypothetical travel of spacecraft from one star system, solitary star, or planetary system to another. Interstellar travel is expected to prove much more difficult than interplanetary spaceflight due to the vast difference in the scale of the involved distances. Whereas the distance between any two planets in the Solar System is less than 55 astronomical units (AU), stars are typically separated by hundreds of thousands of AU, causing these distances to typically be expressed instead in light-years. Because of the vastness of these distances, non-generational interstellar travel based on known physics would need to occur at a high percentage of the speed of light; even so, travel times would be long, at least decades and perhaps millennia or longer.
A starship, starcraft, or interstellar spacecraft is a theoretical spacecraft designed for traveling between planetary systems. The term is mostly found in science fiction. Reference to a "star-ship" appears as early as 1882 in Oahspe: A New Bible.
The Foundation series is a science fiction book series written by American author Isaac Asimov. First published as a series of short stories and novellas in 1942–50, and subsequently in three collections in 1951–53, for nearly thirty years the series was a trilogy: Foundation (1951); Foundation and Empire (1952); and Second Foundation (1953). It won the one-time Hugo Award for "Best All-Time Series" in 1966. Asimov later added new volumes, with two sequels: Foundation's Edge (1982) and Foundation and Earth (1986), and two prequels: Prelude to Foundation (1988) and Forward the Foundation (1993).
The Three Laws of Robotics are a set of rules devised by science fiction author Isaac Asimov, which were to be followed by robots in several of his stories. The rules were introduced in his 1942 short story "Runaround", although similar restrictions had been implied in earlier stories.
A generation ship, or generation starship, is a hypothetical type of interstellar ark starship that travels at sub-light speed. Since such a ship might require hundreds to thousands of years to reach nearby stars, the original occupants of a generation ship would grow old and die, leaving their descendants to continue traveling.
Galactic empires are a common trope used in science fantasy and science fiction, particularly in works known as 'space operas'. Many authors have either used a galaxy-spanning empire as background or written about the growth and/or decline of such an empire. The capital of a galactic empire is frequently a core world, such as a planet relatively close to a galaxy's supermassive black hole, which has advanced considerably in science and technology compared to current human civilization. Characterizations can vary wildly from malevolent forces attacking sympathetic victims to apathetic bureaucracies to more reasonable entities focused on social progress and anywhere in between.
Thiotimoline is a fictitious chemical compound conceived by American biochemist and science fiction author Isaac Asimov. It was first described in a spoof scientific paper titled "The Endochronic Properties of Resublimated Thiotimoline" in 1948. The major peculiarity of the chemical is its "endochronicity": it starts dissolving before it makes contact with water.
Foundation is a science fiction novel by American writer Isaac Asimov. It is the first published in his Foundation Trilogy. Foundation is a cycle of five interrelated short stories, first published as a single book by Gnome Press in 1951. Collectively they tell the early story of the Foundation, an institute founded by psychohistorian Hari Seldon to preserve the best of galactic civilization after the collapse of the Galactic Empire.
The Currents of Space is a science fiction novel by the American writer Isaac Asimov, published in 1952. It is the second of three books labeled the Galactic Empire series, but it was the last of the three to be written. Each occurs after humans have settled many worlds in the galaxy, after the second wave of colonization that went beyond the Spacer worlds, and before the era of decline that was the setting for the original Foundation series.
"Blind Alley" is a science fiction short story by American writer Isaac Asimov. It was first published in the March 1945 issue of Astounding Science Fiction, and later included in the collection The Early Asimov (1972).
The Songs of Distant Earth is a 1986 science fiction novel by British writer Arthur C. Clarke, based upon his 1958 short story of the same title. He stated that it was his favourite of all his novels. Clarke also wrote a short step outline with the same title, published in Omni magazine and anthologised in The Sentinel in 1983.
"C-Chute" is a science fiction short story by American writer Isaac Asimov. It was first published in the October 1951 issue of Galaxy Magazine and later appeared in Asimov's collections Nightfall and Other Stories (1969) and The Best of Isaac Asimov (1973).
In science fiction, hyperspace is a concept relating to higher dimensions as well as parallel universes and a faster-than-light (FTL) method of interstellar travel. Its use in science fiction originated in the magazine Amazing Stories Quarterly in 1931 and within several decades it became one of the most popular tropes of science fiction, popularized by its use in the works of authors such as Isaac Asimov and E. C. Tubb, and media franchises such as Star Wars.
"Not Final!" is a science fiction short story by American writer Isaac Asimov, originally published in the October 1941 issue of Astounding Science Fiction, and included in the 1972 collection The Early Asimov. Its sequel, "Victory Unintentional", is a robot story. These are two of the few stories by Asimov to postulate non-human intelligences in the Solar system.
Sucker Bait is a science fiction novella by American writer Isaac Asimov. It was first serialized in the February and March 1954 issues of Astounding Science Fiction, and reprinted in the 1955 collection The Martian Way and Other Stories. It has also been adapted as an episode of the BBC anthology television series Out of the Unknown.
"He Fell into a Dark Hole" is a science fiction short story by American writer Jerry Pournelle. Set in his CoDominium future alternative history, it was originally published in the magazine Analog Science Fiction and Fact issue of March 1973. The story was reprinted in Warrior: There will be War, Volume V, edited by Pournelle and John F. Carr.
Ark is a 2009 hard science fiction novel by English author Stephen Baxter. It is a sequel to his 2008 novel Flood. Ark deals with the journey of the starship Ark One, and the continuing human struggle for survival on Earth after the catastrophic events of Flood. The series continues in three pendant stories, which are described in the plot summary below.
Space travel under constant acceleration is a hypothetical method of space travel that involves the use of a propulsion system that generates a constant acceleration rather than the short, impulsive thrusts produced by traditional chemical rockets. For the first half of the journey the propulsion system would constantly accelerate the spacecraft toward its destination, and for the second half of the journey it would constantly decelerate the spaceship. Constant acceleration could be used to achieve relativistic speeds, making it a potential means of achieving human interstellar travel. This mode of travel has yet to be used in practice.
Far Centaurus is a science fiction short story by Canadian-American writer A. E. van Vogt, first published in Astounding Science Fiction in 1944. Writer and critic P. Schuyler Miller called it "unforgettable and unforgotten."
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.
