Wormhole

In physics and fiction, a wormhole is a hypothetical topological feature of spacetime that would be, fundamentally, a "shortcut" through spacetime. To comprehend the mechanics behind the phenomenon, visualize spacetime as a two-dimensinal surface that is folded along a third dimension thus creating a bridge between origin point and destination. An object passing through spacetime will travel from origin point to destination at a length of speed and time significantly less than what would be achieved through more conventional means of travel. Wormholes are popular plot devices in many science fiction stories, films and television programs such as Stargate SG-1, Star Trek: Deep Space Nine and Farscape.
