# Hyperspace
**Hyperspace** is a fictional dimension, distinct from ordinary space, in which the normal rules of space and time are altered and travel faster than light becomes possible[1](https://www.dictionary.com/browse/hyperspace). Across most fictional universes, hyperspace is conceived as parallel to ordinary space rather than contained within it: rather than merely speeding up to a tremendous velocity, a ship instead shifts over into a separate realm[2](https://www.sciencefictionclassics.com/what-is-hyperspace-in-science-fiction/). The idea allows stories to span galaxies while keeping travel times within the range of human experience[2](https://www.sciencefictionclassics.com/what-is-hyperspace-in-science-fiction/).
| Key fact | Detail |
|---|---|
| Definition | A fantastical dimension in which the normal rules of space and time are altered, permitting extraordinary actions such as travel at speeds faster than light[1](https://www.dictionary.com/browse/hyperspace) |
| Word origin | "Hyperspace" first recorded 1865–70, from hyper- + space; "hyper-drive" dates to 1946, an invented word used by science fiction writers for anything powering a craft faster than light[3](https://www.etymonline.com/word/hyperspace) |
| Place in FTL taxonomy | One of the three main faster-than-light systems in fiction, alongside warp drives and wormholes[4](https://thespectatorial.ca/2014/01/06/a-little-light-reading-part-2-faster-than-light-travel/) |
| Mechanism | Transitions the ship to an alternate dimension where the light limit no longer applies[4](https://thespectatorial.ca/2014/01/06/a-little-light-reading-part-2-faster-than-light-travel/) |
| Scientific status | Not a current form of space travel; the lack of research and scholarly discussion makes it chiefly a literary device[5](https://www.space.com/32712-warp-drive-hyperspace.html) |
| Signature fictional use | Star Wars, where a hyperdrive and hypermatter fuel let ships "jump" through an alternate dimension, first shown in the 1977 film *A New Hope*[6](https://www.starwars.com/news/star-wars-inside-intel-hyperspace) |
## How it differs from warp drives and wormholes
Science fiction writers draw on three main faster-than-light travel systems, each with a different geometric premise[4](https://thespectatorial.ca/2014/01/06/a-little-light-reading-part-2-faster-than-light-travel/). A warp drive exists in "real" three-dimensional space and fools the light limit by riding inside a bubble of distorted space-time, as described by the Mexican physicist [Miguel Alcubierre](https://www.edgepedia.org/miguel-alcubierre). Hyperspace instead transitions the ship to some alternate dimension where the light limit no longer applies. A wormhole folds space to bring distant points close together[4](https://thespectatorial.ca/2014/01/06/a-little-light-reading-part-2-faster-than-light-travel/).
The scientific differences between these technologies are, for the most part, inconsequential to story, but each carries subtly different implications that can affect narrative and tone[4](https://thespectatorial.ca/2014/01/06/a-little-light-reading-part-2-faster-than-light-travel/). Warp drives can deliver ships to any location, while wormhole-style gates give authors borders that can be attacked, defended, and breached[7](https://www.baen.com/borders). Hyperspace sits between these poles: the usual fictional treatment is not moving faster than light through ordinary space but moving through a separate realm where distant points are effectively closer together[8](https://www.ex-astris-scientia.org/treknology/warp-2007.pdf).
## The idea in fiction
Dimensional travel predates spaceflight. In H.G. Wells's story "The Crystal Egg," the hero finds he can see events on a distant island through a "kink in space," a space warp whereby light travels through hyperspace; [Michio Kaku](https://www.edgepedia.org/michio-kaku), the [City College of New York](https://www.edgepedia.org/city-college-of-new-york) theoretical physicist, notes that Wells used Riemann's wormholes as a literary device in his fiction[9](https://pub.deadnet.se/Books_and_manuals_on_various_stuff/Physics/Michio%20Kaku/Hyperspace-A%20Scientific%20Odyssey%20Through%20Parallel%20Universes%2C%20Time%20Warps%2C%20and%20the%20Tenth%20Dimension_Michio%20Kaku_ISBN-0-385-47705-8-version0.9.pdf). After Einstein's papers on relativity changed how authors approached the problem, stories multiplied with handwaved references to hyperspace, warp, and gates[10](https://www.baen.com/handwavium).
The term itself entered genre vocabulary early: "hyper-drive" is recorded by 1946 as an invented word used by science fiction writers to describe anything that can power a spacecraft faster than the speed of light, contra Einstein[3](https://www.etymonline.com/word/hyperspace).
**Star Wars.** The best-known fictional treatment gives hyperspace a working vocabulary of its own. The [Star Wars](https://www.edgepedia.org/star-wars) galaxy exists in "realspace," but its residents discovered a dimension that broke past any speed barriers; a ship needs a hyperdrive to reach lightspeed and "jump" through the barrier, plus hypermatter fuel, of which coaxium is the most common type, and the coordinates of its destination[6](https://www.starwars.com/news/star-wars-inside-intel-hyperspace). Jumping without coordinates risks smashing into something at incredible speed or being stranded with a busted hyperdrive[6](https://www.starwars.com/news/star-wars-inside-intel-hyperspace). Large objects in normal space cast "mass shadows" in hyperspace, so jumps must be precisely calculated to avoid collisions[11](https://www.starwars.com/databank/hyperdrive/). The franchise even supplies an in-universe origin story: purrgil, massive whale-like creatures living in deep space, can naturally access hyperspace and introduced sentient beings to it, inspiring the invention of hyperdrives[6](https://www.starwars.com/news/star-wars-inside-intel-hyperspace).
**Other settings.** In C.J. Cherryh's novel *Port Eternity*, a spaceship drifts forever through hyperspace darkness while unknown creatures knock on the walls, an image of the hazard of getting stuck there[12](https://explorersweb.com/sci-fi-tropes/). There is no single, agreed "hyperspace" across the genre; it is often only minimally described because it functions as a plot device, whether as a topology where point A is closer to point B or as a dimension without a speed-of-light limit[2](https://www.sciencefictionclassics.com/what-is-hyperspace-in-science-fiction/).
## Scientific standing
Unlike the warp drive, hyperspace has attracted little serious physics. The speed of light in a vacuum, 186,282 miles per second (299,792 kilometers per second), is a hard limit within ordinary space, and science fiction has long postulated a way to beat that barrier so the story can move more quickly[5](https://www.space.com/32712-warp-drive-hyperspace.html). [Seth Shostak](https://www.edgepedia.org/seth-shostak), an astronomer at the [SETI Institute](https://www.edgepedia.org/seti-institute) in [Mountain View, California](https://www.edgepedia.org/mountain-view-california), has said that the lack of research and scholarly discussion on hyperspace makes it more often a convenient literary device than a scientific possibility, and that in reality the concept is "a lot of hype"[5](https://www.space.com/32712-warp-drive-hyperspace.html).
The physics literature does examine related faster-than-light ideas, but they are different mechanisms. To date, superluminal travel exists solely in science fiction, and authors have proposed roughly two mechanisms for achieving it: warp drives and space-time tunnels known as wormholes[13](https://www.sciencedirect.com/science/article/pii/S0094576524003655). Miguel Alcubierre, a Mexican theoretical physicist, showed in 1994 how general relativity permits a spacetime in which a spaceship can move with arbitrarily large speed as seen by outside observers, by a local expansion of spacetime behind the ship and an opposite contraction in front of it; generating that distortion would require exotic matter[14](https://arxiv.org/abs/gr-qc/0009013). Serious study of wormholes, time travel, and the warp drive has been used to understand and constrain possible realistic solutions within general relativity, a review by William A. Hiscock of Montana State University notes[15](https://arxiv.org/abs/physics/0211114). Hyperspace, as a separate dimension entered by a jump, has no comparable formal footing: even the speculative NASA concept literature treats it only as a suggested possible approach to faster-than-light motion, exploring whether nature might provide a higher-dimensional spacetime physically accessible for particles at speeds beyond light[16](https://ntrs.nasa.gov/api/citations/19990023249/downloads/19990023249.pdf).
## Why writers use it
Hyperspace travel became widespread in science fiction because of the perceived limitations of faster-than-light travel in ordinary space, and the concept was made up to get around the issues of traveling above the speed of light[2](https://www.sciencefictionclassics.com/what-is-hyperspace-in-science-fiction/). Once distance loses meaning, the story is free to move, and after decades of use hyperspace has become part of the shared vocabulary of science fiction[2](https://www.sciencefictionclassics.com/what-is-hyperspace-in-science-fiction/). Its rules, once committed to paper, create a fictional reality the author is then expected to maintain; the alternative, arbitrary handwaving, forces writers to keep inventing new ways for the technology to break whenever drama requires it[4](https://thespectatorial.ca/2014/01/06/a-little-light-reading-part-2-faster-than-light-travel/).
