A wormhole is a tunnel that connects two points of space-time, or two parallel universes. One has never been seen and is not proven to exist, although mathematically they are possible.
They are called this way because they resemble a worm that crosses an apple inside to reach the other end, instead of traveling outside. Thus, wormholes are shortcuts in the fabric of spacetime. They allow you to join two very distant points and to arrive more quickly than if you crossed the Universe at the speed of light.
In 1935, physicists Albert Einstein and Nathan Rosen used the theory of general relativity to propose the existence of "bridges" through space-time.
According to Einstein's theory of general relativity, wormholes may exist. They have an entrance and exit at different points of space or time. The tunnel that connects them is in hyperspace, which is a dimension produced by a distortion of time and gravity.
Einstein and Rosen posed this theory by studying what was happening inside a black hole. That's why they are also called the Einstein-Rosen Bridge..jpg)
The first scientist to theorize the existence of wormholes was Ludwig Flamm in 1916. And so far we have seen them in films like Stargate or Contact, in which they are used to travel to other alien societies. Because a wormhole is, above all, a great way to reach great distances in a short time, something like a stellar highway that uses many tunnels to overcome the obstacle of a mountain range.
The term "wormhole" was introduced by American physicist John Wheeler in 1957 and comes from the following analogy, used to explain the phenomenon: imagine that the universe is the shell of an apple, and a worm travels on its surface. The distance from one side of the apple to the other is equal to half of the circumference of the apple if the worm remains on the surface of the apple. But if instead of digging a hole directly through the block the distance it would have to travel would be considerably smaller.
A wormhole could also theoretically allow time travel. This could be accomplished by accelerating the final end of a wormhole at a relatively high speed relative to its other end.
According to a group of scientists from the University of Rochester, it is possible that we may soon "see" a wormhole in a laboratory. At least that is what the calculations have shown, which demonstrate that it is possible to originate these kinds of holes by electromagnetic forces.
As Paul Sutter explains, there is no evidence that wormholes actually exist. Worse, supposing we could find one or were able to make it, the specialist explains that they would be so unstable that they would collide so quickly that nothing, not even light, could pass through them.
But Sutter continues with the game and fantasizes about the possibility that we could create a wormhole that was stable. But even in that case we could not dream of traveling through it. Why?
As the astrophysicist explains, the equations of general relativity theory predict the existence (only at the theoretical level) of so-called white holes, which would be the opposite of blacks. So, while nothing can escape the seconds, the first if you could leave. And what the theory suggests is that the white holes, if any, would be connected to the blacks through the so-called wormholes.
