The overwhelming majority of fiction is set on or features the Earth, as the only planet home to humans or known to have life. This also holds true of science fiction, despite perceptions to the contrary. Works that focus specifically on Earth may do so holistically, treating the planet as one semi-biological entity.
Anti-gravity. Artistic depiction of a fictional anti-gravity vehicle. Anti-gravity (also known as non-gravitational field) is a hypothetical phenomenon of creating a place or object that is free from the force of gravity. It does not refer to either the lack of weight under gravity experienced in free fall or orbit, or to balancing the force of ...
Book 1, Chapter 1. The War of the Worlds is a science fiction novel by English author H. G. Wells. It was written between 1895 and 1897, [2] and serialised in Pearson's Magazine in the UK and Cosmopolitan magazine in the US in 1897. The full novel was first published in hardcover in 1898 by William Heinemann. The War of the Worlds is one of the ...
Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. [1] Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of ...
Time dilation. Time dilation is the difference in elapsed time as measured by two clocks, either because of a relative velocity between them (special relativity), or a difference in gravitational potential between their locations (general relativity). When unspecified, "time dilation" usually refers to the effect due to velocity.
Pastoral science fiction —science fiction set in rural, bucolic, or agrarian worlds, either on Earth or on Earth-like planets, in which advanced technologies are downplayed. Seasteading and ocean colonization. Pirate utopia. Reality Television. Space colonization. Colonization of the Moon. Ecumenopolis.
Extrasolar planets in fiction. Planets outside of the Solar System have appeared in fiction since at least the 1850s, long before the first real ones were discovered in the 1990s. Most of these fictional planets do not differ significantly from the Earth, and serve only as settings for the narrative. The majority host native lifeforms ...
t. e. Black holes, objects whose gravity is so strong that nothing—including light—can escape them, have been depicted in fiction since at least the pulp era of science fiction, before the term black hole was coined. A common portrayal at the time was of black holes as hazards to spacefarers, a motif that has also recurred in later works.
