A wormhole is a hypothetical topological feature of spacetime that would be, fundamentally, a "shortcut" through spacetime.

A wormhole is, in theory, much like a tunnel with two ends each in separate points in [wiki]spacetime[/wiki].

There is no observational evidence for [wiki]wormholes[/wiki], but on a theoretical level there are valid solutions to the equations of the theory of general relativity which contain wormholes. The first type of wormhole solution discovered was the Schwarzschild wormhole which would be present in the Schwarzschild metric describing an eternal black hole, but it was found that this type of wormhole would collapse too quickly for anything to cross from one end to the other. Wormholes which could actually be crossed, known as traversable wormholes, would only be possible if exotic matter with negative energy density could be used to stabilize them

Faster than light Travel [wiki]Wormholes [/wiki]allow superluminal (faster-than-light) travel by ensuring that the speed of light is not exceeded locally at any time. While traveling through a wormhole, subluminal (slower-than-light) speeds are used. If two points are connected by a wormhole, the time taken to traverse it would be less than the time it would take a light beam to make the journey if it took a path through the space outside the [wiki]wormhole[/wiki]. However, a light beam traveling through the wormhole would always beat the traveler. As an analogy, running around to the opposite side of a mountain at maximum speed may take longer than walking through a tunnel crossing it.
