Wormhole

A wormhole, also known as an Einstein-Rosen bridge, is a hypothetical structure connecting disparate points in spacetime. In simple terms, it is a tunnel-like structure that could create shortcuts for long journeys across the universe. The concept emerged from the equations of the theory of general relativity, which describe gravity as a geometric property of space and time, or spacetime. In Hebrew, a wormhole is called חור תולעת (chor tol'at). In Spanish, it is known as agujero de gusano, in French as trou de ver, and in German as Wurmloch. Wormholes are purely theoretical at this point and there is no evidence that they exist in nature. They are often depicted in science fiction as gateways for rapid travel between distant points in the universe or even time travel. The idea of a traversable wormhole, one that could theoretically be used for travel, was first proposed by Albert Einstein and Nathan Rosen in 1935, though their solution to the equations described a non-traversable bridge. Later work by physicists such as Kip Thorne and others has explored the conditions under which a wormhole could be traversable, often involving the existence of exotic matter with negative energy to keep the wormhole stable.
