A wormhole is a speculative structure linking disparate points in spacetime, and is based on a special solution of the Einstein field equations. A wormhole can be visualized as a tunnel with two ends at separate points in spacetime. Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist. They, too, are a possible outcome of Einstein's theory. We place two massive objects in two parallel universes (modeled by two branes). Gravitational attraction between the objects competes with the resistance coming from the brane tension. For sufficiently strong attraction, the branes are deformed, objects touch and a wormhole is formed. A Magnetic 'Wormhole' That Connects Two Regions of Space Was Created in The Lab. Back in 2015, researchers in Spain created a tiny magnetic wormhole for the first time ever. They used it to connect two regions of space so that a magnetic field could travel 'invisibly' between them. However, scientists have observed black holes. Black holes and wormholes are similar, except for one thing: where a wormhole creates a bridge between two points, a black hole leads to a dead end. This dead end is called a singularity. Humans could survive a trip through a wormhole, but there's a catch. Incredibly, the wormhole traveler would only experience roughly a second from one side to the other. But, sadly, anyone not traveling with them would see thousands of years go by. And it's not like you can just push them in. The wormhole theory postulates that a theoretical passage through space-time could create shortcuts for long journeys across the universe. But be wary: wormholes bring with them the dangers of sudden collapse, high radiation and dangerous contact with exotic matter. If you get near a wormhole or a blackhole the part of your body that is closest to the hole would feel a higher gravitational force than a part of your body just a bit further away. This means that you would be torn apart. To create a wormhole on Earth, we'd first need a black hole. This is problematic: creating a black hole just a centimetre across would require crushing a mass roughly equal to that of the Earth down to this tiny size. Plus, in the 1960s theorists showed that wormholes would be incredibly unstable.
