A Dyson sphere is a hypothetical megastructure that encompasses a star and captures a large percentage of its power output. The concept is a thought experiment that attempts to imagine how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's resources alone. Because only a tiny fraction of a star's energy emissions reaches the surface of any orbiting planet, building structures encircling a star would enable a civilization to harvest far more energy.
Childhood's End is a 1953 science fiction novel by the British author Arthur C. Clarke. The story follows the peaceful alien invasion of Earth by the mysterious Overlords, whose arrival begins decades of apparent utopia under indirect alien rule, at the cost of human identity and culture.
Apocalyptic and post-apocalyptic fiction is a subgenre of science fiction in which the Earth's civilization is collapsing or has collapsed. The apocalypse event may be climatic, such as runaway climate change; astronomical, an impact event; destructive, nuclear holocaust or resource depletion; medical, a pandemic, whether natural or human-caused; end time, such as the Last Judgment, Second Coming or Ragnarök; or any other scenario in which the outcome is apocalyptic, such as a zombie apocalypse, AI takeover, technological singularity, dysgenics or alien invasion.
William Olaf Stapledon was a British philosopher and author of science fiction. In 2014, he was inducted into the Science Fiction and Fantasy Hall of Fame.
Scientific romance is an archaic, mainly British term for the genre of fiction now commonly known as science fiction. The term originated in the 1850s to describe both fiction and elements of scientific writing, but it has since come to refer to the science fiction of the late nineteenth and early twentieth centuries, primarily that of Jules Verne, H. G. Wells and Arthur Conan Doyle. In recent years the term has come to be applied to science fiction written in a deliberately anachronistic style as a homage to or pastiche of the original scientific romances.
Out of the Silent Planet is a science fiction novel by the British author C. S. Lewis, first published in 1938 by John Lane, The Bodley Head. Two sequels were published in 1943 and 1945, completing the Space Trilogy.
Star Maker is a science fiction novel by British writer Olaf Stapledon, published in 1937. Continuing the theme of the author's previous book, Last and First Men (1930)—which narrated a history of the human species over two billion years—it describes a history of life in the universe, dwarfing the scale of the earlier work. Star Maker tackles philosophical themes such as the essence of life, of birth, decay and death, and the relationship between creation and creator. A pervading theme is that of progressive unity within and between different civilisations.
Evolution is a collection of short stories that work together to form an episodic science fiction novel by author Stephen Baxter. It follows 565 million years of human evolution, from shrewlike mammals 65 million years in the past to the ultimate fate of humanity and its descendants, both biological and non-biological, 500 million years in the future.
The Space Trilogy is a series of science fiction novels by C. S. Lewis. The trilogy consists of Out of the Silent Planet (1938), Perelandra (1943), and That Hideous Strength (1945). A philologist named Elwin Ransom is the protagonist of the first two novels and an important character in the third.
Earth Abides is a 1949 American post-apocalyptic science fiction novel by George R. Stewart.

Man After Man: An Anthropology of the Future is a 1990 speculative evolution and science fiction book written by Scottish geologist and palaeontologist Dougal Dixon and illustrated by Philip Hood. The book also features a foreword by Brian Aldiss. Man After Man explores a hypothetical future path of human evolution set from 200 years in the future to 5 million years in the future, with several future human species evolving through genetic engineering and natural means through the course of the book.
Farewell, Fantastic Venus is a 1968 American science fiction anthology edited by Brian Aldiss and Harry Harrison. An abridged version was published in the same year under the title All About Venus. It was first published as a direct response to the information returned from the first space probes sent to Venus, especially the first atmospheric probe to return data, Venera 4. The first data was not returned from the surface until Venera 7 successfully landed in 1970.
Neptune has appeared in fiction since shortly after its 1846 discovery, albeit infrequently. It initially made appearances indirectly—e.g. through its inhabitants—rather than as a setting. The earliest stories set on Neptune itself portrayed it as a rocky planet rather than as having its actual gaseous composition; later works rectified this error. Extraterrestrial life on Neptune is uncommon in fiction, though the exceptions have ranged from humanoids to gaseous lifeforms. Neptune's largest moon Triton has also appeared in fiction, especially in the late 20th century onwards.
Pantropy is a hypothetical process of space habitation or space colonization in which, rather than terraforming other planets or building space habitats suitable for human habitation, humans are modified to be able to thrive in the existing environment. The term was coined by science fiction author James Blish, who wrote a series of short stories based on the idea.
The Flames is a science fiction novella by British writer and philosopher Olaf Stapledon. It was published by Secker and Warburg in 1947.

Beyond Time and Space is an anthology of science fiction stories edited by American writer August Derleth. It was first published by Pellegrini & Cudahy in 1950.

All Tomorrows: A Billion Year Chronicle of the Myriad Species and Mixed Fortunes of Man is a 2006 work of science fiction and speculative evolution written and illustrated by the Turkish artist C. M. Kosemen under the pen name Nemo Ramjet. It explores a hypothetical future path of human evolution set from the near future to a billion years from the present. Several future human species evolve through natural means and through genetic engineering, conducted by both humans themselves and by a mysterious and superior alien species called the Qu.
The far future has been used as a setting in many works of science fiction. The far future setting arose in the late 19th century, as earlier writers had little understanding of concepts such as deep time and its implications for the nature of humankind. Classic examples of this genre include works such as H.G. Wells' The Time Machine (1895) or Olaf Stapledon's Last and First Men (1930). Recurring themes include themes such as Utopias, eschatology or the ultimate fate of the universe. Many works also overlap with other genres such as space opera, science fantasy or apocalyptic and post-apocalyptic fiction.
