Wormhole

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 first prediction of a wormhole was made by physicist Hermann Weyl in 1921, and physicist John Wheeler coined the term “wormhole” in 1957.[1] Its relatively unattractive name has probably hurt its popularity and interest level among the general public.
