What is a wormhole?
What is a wormhole? – The wormhole is in fact a special solution to the equations of Einstein’s theory of general relativity, connecting two points in space or time through a tunnel. Ideally, the length of the tunnel is shorter than the distance between the two points, and in fact the wormhole is a shortcut. Although wormholes are untrue and mere hypotheses, many science fiction stories have been made about them and the public is paying attention to them. The simplest type of wormhole was introduced in 1935 by Albert Einstein and Rosen as the solution to general relativity. And for this reason they are sometimes called “Einstein-Rosen Stairs”. Einstein and Rosen began by solving mathematical black holes. These objects contain a singular point and also have an event horizon. They found that the proposed solution could also be applied to the polar opposite of black holes, called “white holes”. These hypothetical white holes are also singular, but they work in the opposite direction of black holes, and nothing can enter their event horizon, and everything in the white hole is immediately ejected. Theoretically, every black hole has a white hole twin. Because these two holes are in different places in space, a tunnel or wormhole connects the two points.
However, wormholes made from a black hole and a white hole are of no particular use because the white holes are not stable. If you put a particle of matter into the horizon of a white hole event, it can never reach the black hole through the wormhole, because nothing can enter the white hole. So the energy of this system is always increasing to reach infinity and the white hole explodes. If we assume that the white hole really exists and there are wormholes between it and the black hole, the only way to enter such a black hole is through the black hole event horizon. Is. The important point is that if an object enters the horizon of a black hole event, it can no longer leave it. So an object can be inserted into the wormhole from the black hole, but it stays there forever and cannot escape. The wormholes are completely unstable, and if a photon or a particle of light enters them, a lot of energy is added to the system and the wormhole tunnel disintegrates. And the wormhole disappears.
Wormhole theory – What is a wormhole?
In 1935, world-renowned physicists Albert Einstein and Nathan Rosen proposed the existence of a bridge through space-time using the theory of general relativity, a path named in honor of the two great scientists Paul Einstein-Rosen. According to this theory, the Einstein-Rosen or wormhole bridge connects two different parts of space-time. Theoretically, bypassing this shortcut, one can move from one point in space-time to another. The wormhole consists of two openings and a throat that is round in shape and the throat is flat and elongated, But it can also twist the throat and even go a long way. Mathematical Equations Einstein’s theory of general relativity predicts the existence of wormholes; But so far no wormholes have been discovered, the negative mass of which affects the light by gravity and prevents light from leaving the wormhole. The crater probably consists of two black holes; However, turning a dying star into a black hole cannot produce wormholes.
Among the wormholes – What is a wormhole?
There are many science-fiction stories about wormholes and their passage through space portals, but in reality, such a journey is much more complex than in Hollywood movies. The first problem with such trips is that forecasts put the size of the wormhole at about 10 to 33 centimeters; Of course, with the expansion of the world, it is possible to expand to larger sizes. Another problem will be the internal stability of these space stairs, according to Einstein-Rosen’s theory, wormholes are useless for space travel because they are highly unstable and will collapse. New research shows the existence of mysterious substances that hold wormholes open for a long time when they enter them. This mysterious substance differs from dark matter and antimatter in that it contains a density of negative energy and large negative pressure. This material has only been seen as part of quantum field research by affecting some vacuum environment behaviors. If a sufficient amount of this substance is added to a wormhole, either naturally or artificially, it may become stable enough to be used as a method of sending information or even transporting passengers, but with the addition of ordinary matter such as humans, it is still added. Will suffer from instability and collapse. Wormholes do not connect only two different points in space; Rather, they may even connect two different worlds; Some scientists even believe that time travel would be possible if one of the wormhole craters moved in a certain way, yet Stephen Hawking finds that impossible.
Black holes are the door to other worlds
According to Einstein’s theory of relativity, black holes are points in space where their singularity is at its highest, and even the laws of physics are broken. These strange points are the only candidates for the wormhole entrance. A new theory called quantum gravity, or LQG, has been proposed for the first time as a way to integrate the laws of quantum mechanics and general relativity. According to this theory, in a black hole, by collecting materials and pouring them under strong gravity, space opens up in another way, for example, if you fall into a black hole, according to the theory of general relativity, you fall into a deep well; But instead of hitting the bottom of the well, you are squeezed into a very small space. In fact, you do not fall to the bottom of the well, but your singularity increases to infinity. Will be found and thrown into space-time as you are swallowed by a black hole. Black holes may be tunnels to other parts of space-time, but where? Interestingly, LQG theory emerges as a competitor to the Big Bang theory. According to this theory, the world was not created by the explosion of a point of infinite density; Rather, another world has collapsed in another tunnel, and in this dimension, it has created our world. There is insufficient evidence to support this theory, But scientists are trying to find unknown links to this beautiful theory.
