Féreglyuk

Féreglyuk is the Hungarian word for wormhole. In theoretical physics, a wormhole, also known as an Einstein-Rosen bridge, is a hypothetical topological feature of spacetime that would fundamentally be a shortcut connecting two separate points in spacetime. The concept arises from the equations of Albert Einstein's general theory of relativity.

Wormholes are predicted to be traversable only if they are "traversable wormholes," which require exotic matter with negative mass-energy density to prop them open. Without such matter, a wormhole would collapse too quickly for anything, even light, to pass through. The existence of exotic matter is not confirmed, and thus the existence of traversable wormholes remains speculative.

The idea of wormholes has captured the imagination of science fiction writers and has been a popular concept in various stories and films, often depicted as a means of faster-than-light travel or time travel. However, within the framework of current scientific understanding, the practical application of wormholes for such purposes is highly uncertain. The study of wormholes continues to be an area of active theoretical research, exploring their properties and potential implications for cosmology and fundamental physics.
