'Hyperspace' may refer to:
· Space above the third dimension. See also higher dimensions.
· A fictional space in which the usual laws of physics may be circumvented allowing faster-than-light (FTL) travel or time travel. One common model of FTL is that a starship can somehow exit normal space to a domain in which the light-speed limit no longer applies, or the geometry of the realm permits quick transit between points widely separated in normal space. General use of the term for such domains dates back at least to the 1940s; it is found in Isaac Asimov's Foundation novels and probably predates those. See also wormhole.
