Are there parallel worlds?

For many years now, the minds of science fiction have been tormented by thoughts abouthow to explain to the reader or viewer that parallel worlds exist. It is also necessary to explain how it all works, why life is there and why it is similar or not like ours. All these considerations on the topic of parallel universes rarely lead to any specific answers. If everything was so simple, the best physicists would not puzzle over the subject of quantum states and how electrons can exist in two places at the same time. As long as they continue to do this and exchange only theories and arguments, without giving specific facts and evidence, you and I have a great opportunity to reflect on the topic of the exciting minds of parallel worlds. In the end, the reasoning of scientists is no more supported by facts than ours.

The existence of parallel worlds is not proven, but not disproved.

What are parallel worlds

There is no clear definition of this concept, sinceaccording to various theories, some mean one thing, while others speak of something completely different. If you try to somehow generalize all theories, then the parallel worlds are other realities in which we live, others, and possibly someone else.

In any case, this, so to speak, is another world that we can hardly get into. However, one of the theories says that these worlds periodically collide and exert a gravitational effect on each other. It even leaves its mark on the relict radiation. However, we’ll talk about this a little lower.

There are different theories about parallel worlds. Some explain this phenomenon from the point of view of religion, others from the point of view of magic, and still others from the point of view of physics. It is about the physical explanation that we will talk about today.

Of course, parallel worlds may look like this, but only in the movies

How to prove the existence of parallel worlds

One of their theories is that parallel worldsexist. Yes, that’s so simple. If you believe this theory, first proposed by the American physicist Hugh Everett, there is at least one world parallel to ours.

He called his reasoning the theory of the probable set of worlds. It is based on the statements of scientists from the fieldquantum physics. According to these statements, an electron can exist in two places in space at the same time. Such a property is called a superposition of two states.

An interesting feature of this superpositionis that as soon as we try to understand where this electron is located, for example, if we have an effect on it, it will immediately move. Moreover, although they are a copy of each other, but if you try to determine their position, it turns out that we will see only one. In fact, all this is more like some kind of divorce, they say you do not see, but it is, however it is part of quantum physics. The part of quantum physics, which has a number of assumptions and basic rules, without which it is simply impossible to explain everything that happens in the world. Such rules are suitable for many phenomena; therefore, they are the laws of quantum physics. We can only believe in them.

Hugh Everett's theory takes evidencethe existence of parallel worlds is just such a behavior of quantum particles. That is, if we try to identify the electron in space and understand where it is, then we ourselves will become a quantum object and find ourselves in two states. In one of them one electron will be available to us, and in the second - another. That is, these are parallel worlds based on a superposition of states.

So it is with the famous Schrödinger cat,which, according to a hypothetical experiment, was immersed in a box of poison and he was alive and dead at the same time. Just when we opened the box and saw a poor cat in one state, in a parallel world, someone saw him in a different state. This is another important rule of parallel worlds - opposite events occur in them.

Is it possible to create a quantum computer? Scientists say no

Moreover, the number of such worlds may be greatertwo. It is limited only by the number of probable outcomes of any event. But to say that events occur in another Universe, which is simply connected with ours at the quantum level, is not necessary. According to the theory, the Universe is only one, and the given examples of parallel worlds are only layers of this single Universe, which are formed every time an event occurs that has several different outcomes.

That we do not create a separate universeexplains why we cannot get intoParallel Worlds. We cannot switch to another layer. There are other we who take opposite decisions and go our own way. For them, our world is parallel.

Are you ready to visit parallel worlds? No, it's not possible.

In reality, such a theory simply links quantum concepts of superpositions with the real world and tries to explain the existence of parallel worlds on the basis of this.

Parallel worlds in terms of string theory

There are two main theories in the world forthe explanations for everything are the general theory of relativity and quantum field theory. The first explains the interaction in the macrocosm, and the second in the microcosm. The problem is that if you imagine both worlds on the same scale, that is, just imagine our world, then both of these theories contradict each other.

As soon as they do not try to visualize string theory, but it doesn’t work out very well.

In order to explain everything in the world to one commontheory, scientists in the 1970s actively clung to string theory. The strings were somewhat arbitrary, which was supposed to explain the physical characteristics of the smallest particles and their interaction with other particles at any scale, but later it turned out that this theory does not always work and something else needs to be sought.

On its own this does not prove the existence of parallel worlds, but in 1998 cosmologist Max Tegmar put forward a theory that gives reason to think about the existence of other Universes with other physical constants other than ours.

While we are sitting here, scientists have come closer to understanding why the universe exists.

Many scientists are hooked on this theory andsuggested that these universes are our parallel worlds. Theoretically, they can even be reached, especially if you go through a black hole, which, in theory, connects our Universe with others.

In response to those who deny the existence of othersUniverses, supporters of the theory argue that our idea of ​​universes comes down only to what we see. That is, to that space around us, which corresponds to the distance traveled by light in 13.8 billion years. That is exactly how much has passed since the time of the Big Bang and we see only those stars, galaxies and worlds from which the light managed to reach us. Perhaps in a billion other years, light from other universes will reach us.

Universes after the Big Bang can exist anywhere and anywhere.

To deny the existence of other universes within the framework of this theory is the same as standing on the seashore and saying that there is no other shore. We do not see him.

Many scientists also argue that theseUniverses are our parallel worlds. Some even rely on changes in relict radiation, arguing that changes in its behavior are the result of a collision of universes that seem to float in the great ocean and periodically collide with each other.

Background radiation - thermal radiation that arose in the eraprimary formation of hydrogen and uniformly fills the universe. For its discovery in 1978, Arno Penzias and Robert Woodrow Wilson received the Nobel Prize.

Is our world the only one

Most scientists agree thatconsider our world the only one, at least, stupid. And to assume that there are a lot of worlds, much easier than to say that he is only one. If you have a clearly formed opinion about this, please write in our Telegram chat - we will discuss it.

Moreover, quantum physics and lawsthe interactions of everything in the world constantly bring even more confusion to the reasoning and debate of physicists. We can only believe or not believe in the reasoning of scientists. All the same, we are not given to understand all the secrets of the universe and how everything is arranged. Scientists also have not been given this and will not be given for many more years. But they dedicate this life and are a couple of steps closer to the solution than we are. That's just up to this clue several hundred kilometers. And to her understanding, and even more.
