HELLO EVERYONE. Wormhole, originally also known as the Einstein-Rosen bridge - a hypothetical topological property of space-time that is a kind of "shortcut" between at least two regions of the universe or a kind of bridge connecting the universes. Wormholes are the subject of research and disputes among modern physicists. So far, no observations of their existence have been recorded, although Albert Einstein's theory of general relativity admits the existence of tunnels in some space-time models. https://youtu.be/em8u6yQ6Oxs
