Scientists often shake the whole science world by giving different kinds of theories. One such theory that we know as the Parallel Universe. In 1954, Hugh Everett, a research scientist at Princeton University, gave it. He believed that the universe in which we live is not the only universe. A lot of the Parallel Universe around us, all looks like a science fiction movie. But why would a scientist want to waste his entire career by giving such a strange theory? Come, let us know what Hugh Everett was thinking about this Parallel universe and what they wanted to prove from this strange theory.
Commencement of Parallel universe Theory
Things start from the nineteen hundred when a great scientist Max Planck told the world that the laws of this universe do not work at the quantum level the way we think, the quantum level is the lowest. As far as scientists have come to find the particle till today when Max Planck put his Quantum model in front of the world, everyone was surprised how this is possible. After all, how can a particle be found in two stages? One is in particle form and the other is in a waveform. That is, we know that wave-particle is found in two or more forms at the same time under the name of Superposition. While a particle can be in more than one state at a time, we will talk again to understand Quantum physics properly. Today we only talk about the Parallel Universe.
Interpretation of parallel Universe theory
The thing to understand here was that Quantum Physics was found to be correct in various experiments, but scientists did not have any concrete accreditation of how and why this happens. How a particle can be in two states at the same time. Hugh Everett then presented the theory of his Parallel Universe to prove it.
To understand the theory of the Parallel Universe properly, we have to understand the work of scientist Erwin Schrodinger. We can understand this from his famous cat story. If a cat is locked in a box and a small box of poisonous gas is kept in that box itself. Then what we Can say for sure that the cat is alive or the cat is dead. Here they want to explain that without opening the case we cannot find that but the state and as soon as we are packed then we get one of those two states immediately. For example, if the cat came out alive, it was one of two possibilities, which is now true. Even if the cat were dead, it would have been one of two possibilities. The cat cannot be both dead and alive simultaneously.
According to another scientist Heisenberg who gave the Heisenberg uncertainty Principle, When we detect quantum matter, we influence the behavior of that metal. Meaning we cannot get the exact information about that matter. We cannot ascertain the exact position and speed of his movement at a certain time. Either we will get the position right or we will get its rotation speed right. It is difficult to meet both, simultaneously.
Here another scientist Neil Bohr said that when we try to know whether the cat is alive or dead, then we affect the behavior of that knowing. In the language of quantum particles, when we try to know the exact position of the particle, only then we break the principle of its superposition. As I said earlier, superposition is the principle in which a particle gives the impression of being in more than one state. It's a little weird to understand.
But what he meant to say is that as we try to find the state of the cat, then we choose one of the two possibilities and one possibility also affects the other. So far both the states were FIFTY FIFTY. The cat may be alive, the cat may also be dead, but now one is a state hundred percent and the other is zero percent. When we influenced one state, it affected another state as well. This cat story is presented in a slightly different way to explain the behavior of the quantum particle.
Hugh Everett III who expressed the thinking of the Parallel Universe, accepted these principles broadly, but he had a problem with what Neil Bahr had said. He said that one of the two possibilities does not affect the other possibilities, rather both of them are correct. He said that whenever there are any two possibilities of a particle, both of them are true. The only difference is that even if the cat is alive in your universe, its second possibility is true that the cat is dead but this second possibility is not part of your universe. This is part of your parallel running the second universe.
He believed that whenever there is more than one possibility of an event, then the universe breaks into those possibilities, and a separate universe is created to make every possibility come true. He believed that based on the possibilities of events in nature, the Parallel Universe is formed.
Let's understand this a little bit more. If there ever comes a possibility in your life where you can die but you survive only then a new universe was born in which the possibility of your death was true in that other universe. According to First Universe Theory, you can never contact or go to that second universe because then two different possibilities will become one and in that case, there will not form a broken universe or Parallel Universe.
However, to prove this theory, there has not yet been any major experiment that can test its veracity, this is not the only theory that considers the Parallel Universe a variety. There is another such theory called String Theory, which we will know later how scientists in String Theory are claiming that we can come in contact with Parallel Lead Basis.
