This article is about the science-fiction concept of travel (see also Hyper jump). For the data storage device, see JumpDrive.. Jump drive is a name given to a method of traveling faster than light (FTL) in science fiction. Related concepts are hyperdrive and warp drive. The key characteristic of jump drive (as the term is usually used) is that it allows a starship to be instantaneously teleported between two points.
Characteristics There are two main variants of jump drives. The first requires a ship to travel through normal space to a specific jump point. Once at that point, the jump drive is used to move to another jump point, for example the Capsule Drive in the computer game Independence War, which could only make jumps between Lagrange points. The second variant is for a ship to execute a jump from anywhere in normal space (although sometimes limited by needing to be a certain distance away from a gravity well) and move directly to any other location. In most fictional universes, the total distance per jump is limited and multiple jumps may be needed to reach the final destination. Jump drives often require significant power and many universes require time to "re-energize" the jump drive after a jump, thereby limiting the frequency at which jumps can be executed. These factors can allow writers to build dramatic tension by showing characters struggling to reach a jump point, or to recharge their drive, before their foes reach them. Examples Jump drives are the main FTL technology in many science fiction universes including: See also | ||||||||
