What is a wormhole in Physics ?
A wormhole is theoretical tunnels that allow you to travel quickly across distances in the Universe, connecting different points of the space-time fabric. The existence of a wormhole has not been proven so far; moreover, even the theoretical infrastructure of the wormholes is controversial. So scientists disagree that a wormhole can really exist.
Wormholes were first proposed by Ludwig Flamm in 1916. Flamm realized that when he overhauled Einstein’s General Theory of Relativity, a celestial body, which he called the white hole, was the opposite of the black holes, theoretically possible. He thought that a bridge could be established between an white hole and a black hole.
In 1935, Albert Einstein and Nathan Rosen expanded this idea using the General Theory of Relativity and developed the wormhole theory called the Einstein-Rosen Bridge.
