For many years the minds of science fiction was plagued by thoughts about how to explain to the reader or audience, that parallel worlds exist. Also need to explain how it all works, why there is life and why it is similar or not similar to ours. All of these arguments on the topic of parallel Universes that rarely lead to any concrete answers. If only it were that simple, the best physicists would not break heads on the subject of quantum States and how electrons can exist in two places at the same time. As long as they continue to do it and only exchange theories and reasoning, giving concrete facts and evidence, we have a great opportunity to speculate on the disturbing minds of parallel worlds. In the end, the reasoning of scientists is not more factual than ours.
What is parallel worlds
A clear definition of this concept, as according to different theories, some mean one thing and others say something quite different. If you try to generalize all the theory, that parallel universes are other realities in which others live, we, and possibly someone else.
In any case, it is, so to speak, another world, which we can hardly to get. However, one theory says that these worlds are experiencing and have gravitational influence on each other. It even leaves its mark on the CMB. However, this will be discussed below.
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. Of physical explanation we will now discuss.
How to prove the existence of parallel worlds
One theory says that parallel worlds exist. Yes, just like that. If you believe this theory, first proposed by American physicist Hugh Everett, there is at least one world parallel to our own.
He called his argument the theory of the likely many worlds. It relies on the statements of scientists from the field of quantum physics. According to these statements, the electron can exist in two places in space simultaneously. This property is called superposition of two States.
An interesting feature of this superposition is that as soon as we try to understand where is the electron, for example, and provide him effects, he immediately moved. Thusthey are copy of each other, but if you try to determine their position, it appears that we will see only one. In fact, all it’s more like some kind of Scam, they say you can’t see, but it’s there, but it is part of quantum physics. The part of quantum physics, which has several assumptions and basic rules, without which it is simply impossible to explain what is happening in the world. These rules apply to many phenomena, so they are the laws of quantum physics. We just have to believe in them.
The theory of Hugh Everett takes the basis of evidence of the existence of parallel worlds it is the behavior of quantum particles. That is, if we try to identify the electron in space and understand where he is, we’ll get a quantum object will be in two States. In one of them we will be available to one electron, and the second — another. That is, it has parallel worlds, based on a superposition of States.
Similarly with the famous schrödinger’s cat, which, according to the hypothetical experiment was immersed in a box with poison and he was alive and dead at the same time. Just when we opened the box and saw the poor cat in the same state, in a parallel world someone saw him in a different state. This is another important rule of parallel worlds in them are opposite events.
The number of such worlds can be more than two. It is only limited number of possible outcomes of any event. But to say that events happen in a different Universe, which simply relates to our at the quantum level, is not necessary. According to the theory, the universe is only one, and the examples of the parallel worlds are the only layers that a single Universe that form every time there is an event that has several different outcomes.
The fact that we don’t create a separate Universe, explains why we can’t get to parallel worlds. We can’t go to another layer. There are others we who take the opposite decision and go my own way. For them our world is parallel.
In reality this theory is just links the quantum concepts of composition with the real world and attempts on this basis to explain the existence of parallel worlds.
Parallel worlds from the point of view of string theory
In the world there are two main theories that can explain only General relativity and quantum field theory. The first explains the interaction between the macrocosm and the other in the microcosm. The problem is that if we imagine both worlds in one scale, that is just to represent our world, both of these theories contradict each other.
In order to explain everything in the world is one common theory, scientists in the 1970’s actively caught in string theory. The strings were something conditional that is supposed to explain the physical characteristics of fine particles and their interaction with other particles at any scale, but it later emerged that this theory does not always work and need to find something else.
In itself this does not prove the existence of parallel worlds, but in 1998, the cosmologist Max Tegman put forward the theory that gives a reason to think about the existence of other Universes with other physical constants different from ours.
Many scientists clung to this theory and suggested that these Universes is our parallel worlds. Theoretically even can be reached, especially if you go through a black hole, which, in theory, and connects our Universe with others.
In response to those who refute the existence of other Universes, proponents of the theory argue that our view of the Universes boils down to just what we see. That is, to ensure the space around us, which corresponds to the distance traveled by light for 13.8 billion years. Exactly how much has passed since the Big Bang and we only see those stars, galaxies, and worlds whose light has had time to reach us. Perhaps in another billion years we will reach the light from other Universes
To deny the existence of other Universes in the framework of this theory is still that standing on the shore of the sea and say that the other shore does not exist. We don't see it.
Many scientists also argue that these are our Universes and parallel worlds. Some even rely on the changes in the background radiation, claiming that changes to its behavior are the result of a collision of Universes that float in the ocean and periodically collide with each other.
The CMB - the thermal radiation, which originated in the era of the initial formation of hydrogen and uniformly fills the Universe. For its opening in 1978, Arno Penzias and Robert Woodrow Wilson won the Nobel prize.
Is our world only
Most of the scientists agree, what is considered our only world, at least, silly. And to assume that the worlds there are so many, much easier than to argue that it is only one. If you have a well formed opinion about this, nieste in our Telegram chat — discuss.
