It is a name by analogy for what in physics is known as "Einstein-Rosen bridge" (among other names), which is a passage created through space (and which includes time) to join two points crossing a fourth dimension, which would considerably reduce distance and travel time. The name was coined by the American physicist John Wheeler, who explained it as if a worm wanted to walk on a fruit from one point to the opposite, and instead of surrounding the surface make a hole to go through it inside and shorten the distance.
