Hyperspace

Hyperspace is a superluminal method of travel. It is an alternative "sub-region" of space co-existing with our own universe which may be entered using an energy field or other device. Hyperspace is a physical place that can be entered and exited. Once in hyperspace, the laws of general and special relativity do not behave in the same way when compared to normal outer space, allowing travelers through hyperspace to go great distances without being physically present in normal space and taking less time, measured from normal outer space, to travel said distance.

The technologies used to enter hyperspace are hyperdrive or jump drive, popular in the Star Wars and Stargate universes.
