Development of wormhole theory

Wormhole is hypothetical object such as a short-cut tunnel connecting two points in space-time.

Shortly after the advent of general relativity by Einstein, theories of black holes and white holes were proposed. The first appearance of a “tunnel structure” was in 1916 by the Austrian physicist Ludwig Flamm just after the discovery of Schwarzschild’s black-hole solution.

Almost immediately after the introduction of quantum entanglement in 1935, Einstein and Rosen attempted to explain quantum entanglement using special relativity and the speed of light. Einstein and Rosen proposed a “bridge structure” between black-holes in order to obtain a regular solution without a singularity.

Einstein and Rosen found that, theoretically, every black hole is paired with a white hole. Because the two holes would exist in separate places in space, a tunnel — a wormhole — would bridge the two ends.

A white hole, unlike a black hole, repels any matter that goes to it. Some physicists think that matter swallowed by a black hole is thrown out on the other side and into a white hole.

The name “wormhole” was coined by John A. Wheeler in 1957, and its fantastic applications are popularized after the influential study of traversable wormholes by Morris and Thorne.
