Editing Megastructure (section)

===Stellar scale===
* The [[Dyson sphere]] has appeared in [[Dyson spheres in popular culture|many works of fiction]], including the ''[[Star Trek]]'' universe.
* [[Larry Niven]]'s series of novels beginning with ''[[Ringworld]]'' centered on, and originated the concept of a ringworld, or Niven ring. A ringworld is an artificial ring with a radius roughly equal to the radius of the Earth's orbit (1 [[Astronomical unit|AU]]). A star is present in the center and the ring spins to create [[g-force]]s, with inner walls to hold in the atmosphere. The structure is unstable, and required the author to include workarounds in subsequent novels set on it.
* In the [[manga]] ''[[Blame!]]'' the megastructure is a vast and chaotic complex of metal, concrete, stone, etc., that covers the Earth and assimilates the Moon, and eventually expands to encompass a volume greater than the orbit of Jupiter.
* In ''White Light'' by [[William Barton (writer)|William Barton]] and [[Michael Capobianco]], a [[Topopolis]] is presented as taking over the entire universe.
*In the [[Heechee Saga]] series by [[Frederik Pohl]], a race of pure energy beings called The Foe have constructed the Kugelblitz, a black hole made of energy and not matter.
* In the [[Xeelee Sequence|Xeelee series]] of books by [[Stephen Baxter (author)|Stephen Baxter]], the eponymous alien race constructed the [[Ring (Stephen Baxter novel)|Ring]], a megastructure made of [[cosmic string]]s, spanning over 10 million light years.
* In ''[[Freelancer (video game)|Freelancer]]'', The Dom'Kavosh's Dyson shell that is inhabited by a drone race created by the Dom'Kavosh, Nomads. This is reached via a hyper gate, created by the same creators as the Dyson sphere.
* The [[Saga of Cuckoo]] series novel ''[[Wall Around a Star]]'' mentions a proposal to build a super dyson sphere, completely enclosing the [[Galactic Center]].
* The title of the novel ''Helix'' by [[Eric Brown (writer)|Eric Brown]] directly references a stellar-scale helical megastructure. Different types of environments and habitats are interspersed along the structure, while their varying distance from the central star affects the climate.
*The player's central quest in computer game [[Dyson Sphere Program]] is to construct a [[Dyson sphere]]. Gameplay focuses on constructing planetary scale factories as a means towards this end.
* The Quarg in the game Endless Sky are shown building a massive ring around one of their stars, which is most likely around one astronomical unit in diameter. A completed version of this can also be found in another location.
* In computer games [[Space Empires IV]] and [[Space Empires V]], the player can construct sphereworlds and ringworlds around stars.
* [[Dennis E. Taylor]]'s 2020 novel ''Heaven's River'' features a ''[[Topopolis]]'' built around an alien system. Different segments of the structure are built with artificial climate and weather.
