The door to time and space – what is the wormhole?

Last updated on June 22, 2019

Many scientists and astronomers believe that wormholes are real. There are many things in astrophysics and theoretical physics that have not been fully confirmed, but as scientists have said, “Mathematically plausible” means that they are possible. It is believed that if the wormholes do exist, they are a primitive tiny wormhole that began to swell at the beginning of the universe after the Big Bang.

Popular fiction and Hollywood seem to be obsessed with space and time. From the recent sensational sensations of Interstellar and The Martian to the incredible discoveries that have recently emerged inside and outside our Milky Way, everyone’s eyes seem to focus on the vast In space. Although our exploration of the universe will never end, there are some historically puzzling propositions that have aroused our interest. One of the most famous examples is the concept of wormholes.

Some people think that wormholes are a shortcut to the universe, while others think they may be a way to travel through time. The truth is that they are fascinating, complex, and confusing for some people, even if they have seen Interstellar.

Still do not understand? Ok, let’s take a deep look at one of the biggest mysteries and the most exciting assumptions of the universe.

Wormhole science

Without further study of general relativity and advanced astrophysics, let us try to understand the most basic form of wormholes – bridges. In fact, wormholes are technically known as the Einstein-Rosen Bridge because they were originally proposed by Albert Einstein and Nathan Rosen in 1935. These bridges spanning time and space are considered to be possible because all mass objects have a bending effect on time and space.

The proposition is that two huge objects (mouths) can bend time and space to a point so that they can be connected to each other through a bridge (throat). Of course, in theory, this will greatly shorten the travel time between these two points in the universe, which may be billions of light years away, or only a few feet away. Another more unusual explanation is that wormholes can not only connect to two distant places in our present universe, but also connect to another universe!

This throat can be a straight line or a curved path that goes through a higher dimension to the very distant “other side.” A curved two-dimensional plane is usually the best way to imagine this situation. When two objects of considerable mass bend the plane in opposite directions, it is theoretically possible to establish a connection. We say “theoretically” because, although the wormhole conforms to the principle of general relativity, no wormhole has been found.

Now you may be thinking: “If we have never found a wormhole, how do we know that they exist?” Well said. There are many things in astrophysics and theoretical physics that have not been fully confirmed, but as scientists have said, “Mathematically plausible” means that they are possible. It is believed that if the wormholes do exist, they are a primitive tiny wormhole that began to swell at the beginning of the universe after the Big Bang.

Well, then based on the assumption that wormholes can and do exist, the question everyone is thinking about is…when can we start using them? emmm, the peculiar nature of wormholes makes them very distant in the future. idea. There are still many basic problems in finding, using, and even developing wormholes.

Wormhole problem

One of the most popular theories about how wormholes form is the fact that wormholes can be made up of two black holes that serve as the “mouth” of the wormhole, and the unknown centers of these black holes, and possibly their singularities, constitute The throat of the wormhole. Of course, the problem with this proposition is that it seems that it is never possible to study the inside of a wormhole, nor can it see the opposite side, because nothing can escape the gravitational pull inside the black hole—even light can’t.

The Einstein-Rossen Bridge is a real problem because they collapse and disappear very quickly, so it is almost impossible to detect, identify and study them. In addition, some theorists believe that wormholes may occur on a microscopic scale, suddenly appearing or disappearing at a quantum level that we are currently unable to observe.

That is to say, when there are problems or obstacles in theoretical physics, there will always be someone who comes up with a solution. If the main problem with the study and use of wormholes is that their size and duration are too short, if this problem can be solved, then wormhole research can make progress. With this in mind, there is a theory that “foreign matter” may stabilize wormholes, allowing them to be used for longer periods of time and providing more stability. Foreign matter is different from dark matter, but it does contain a lot of negative and negative energy density. This type of material is only found in limited vacuum experiments, but if it is added naturally or artificially to the wormhole, it can theoretically widen the wormhole—even open—for space travelers or equipment. Can pass.

In addition, it is predicted that there will be a large amount of radiation at the singularity of the mouth and certain wormholes, which proves to be immediately lethal and will destroy anything close to it. Strong gravitation can also tear any spacecraft or humans into pieces before they pass through the wormhole. If a black hole can tear a star, I don’t want to imagine what it will do to humans.

Are there different types of wormholes?

There are many different types of wormholes that may exist, some of which we want to make for my use, while others must mean death. Knowing the difference between the two can be important.

A wormhole that can be traversed: a wormhole in which humans can travel multiple times in both directions along the space-time bridge without any harm. These wormholes require foreign matter to remain stable and open, as foreign materials resist the natural tendency of the wormhole to contract immediately.

Schwarzschild wormhole: This wormhole can only pass in one direction, an example of the Einstein-Rosen bridge. After the singularity is compressed to an incredibly finite density, you will reverse the same process at the entrance of another black hole.

Is it possible to travel through the wormhole?

Although the problem about wormholes is still inconclusive, because there are still many unsolved mysteries about wormholes, it is widely believed that wormholes will not let travelers return to the past through time and space. Simply put, time travel seems to be possible within the scope of general relativity, but this does not affect the reality of quantum physics.

While the discovery of wormholes will be an incredible moment in the history of astronomy, many other problems and characteristics of wormholes may prevent humans from experimenting with any time travel theory in the coming decades.
