Answer To Question 188

A188: A wormhole in space (also known as a Einstein-Rosen Bridge, named for Albert Einstein and Nathan Rosen) is a mathematical solution to Einstein's theory of General Relativity. A Lorentzian wormhole would theoretically provide a shortcut through widely-separated parts of space-time, through a black hole and out of a white hole(moving faster than the speed of light). Many physicists believe that wormholes have no physical reality because wormholes require "exotic matter," matter which is repelled by gravity (rather than attracted by it). John A. Wheeler coined the term wormhole in the mid 1950s.
