A wormhole, in science fiction, is a passage from one location in three-dimensional space to another. It is based on the concept that space has more than three dimensions, and that 3D space can be "folded" within 4D space much as a 2D piece of cloth can be folded within 3D space. The General Theory of Relativity says that wormholes may exist.

The significance of a wormhole is that it would allow a trip through it to take much less time than a journey between the same two points in conventional space. The mouths of a wormhole may be at any two points in spacetime, including at different times; this would allow time travel by going through the wormhole.[1]

Some scientists speculate that black holes might be entrance portals to wormholes, leading to hypothetical white holes.

The first prediction of a wormhole was made by physicist Hermann Weyl in 1921, and physicist John Wheeler coined the term “wormhole” in 1957.[2]
