Parallel Universes Theory - Theory about Parallel Worlds
The Parallel World is a world that runs parallel to the world of reality. Besides the life we know and we live now, there are one or more other lives that also run together in a parallel world.
Initially the parallel world was only an imagination in fiction, but now more and more theories are being used as bridges to explain and support the existence of parallel worlds. Physics scientists are at the forefront as those who try to explain the possibility of their existence.
Physicist Dr. Michio Kaku analogous to the existence of a parallel universe for us as there is an outside area of the pond for a gourami that lives in a pond. The gouramy can't see the area outside the pond because of the limitations of the 'technology' it has. Likewise, humans cannot see the other universe for the same reason. Although gouramy can't see other life outside the pond, but he can know there is another life from the vibration he felt through waves on the surface of the pond due to raindrops. The vibration felt by the gouramy is gravity and light from other universes.
The basis of the parallel Universe theory is the infinity of the universe which gives the possibility of another universe. At present there are an estimated 1011 galaxies in the universe. So, it's not impossible if in addition to the galaxy we live there is a life that is also going on. Quantum physicists clearly believe that every second created a parallel world of people, which contains possible events, including the opposite of the events we experience in the real world. For example in the real world we can cross the road safely. In the first parallel world, we can only successfully cross over but then fall down, in the next parallel world we can't even be helped because when crossing a car that is speeding towards us.
Max Tegmark, a physics and astronomy professor at Pennsylvania University, strongly believes in the existence of this parallel universe. In one of his articles, which was tipped as 'parallel Universe', Max Tegmark revealed that there were 4 levels of parallel universe.
Level I: Beyond Our Cosmic Horizon:
It is a parallel universe theory that has the smallest level of controversy. This theory states that the parallel universe cannot be seen because it is outside the horizon line of our universe. The analogy is like we see a ship in the middle of the sea. We cannot see the ship if it is outside the horizon. But if the ship approaches us, and enters the horizon, we will be able to see the ship little by little. Parallel universe level I by physicists described that our universe is like an air bubble jostling in a space called the universe.
Level II: Other Postiflation Bubbles:
This level states, if the universe at level I can be grouped into one multiverse, then the universe has many multiverses. This theory is based on the Chaotic Eternal Inflation theory, which states that our universe continues to grow ever larger since the big bang happened until now. This theory states that we can never see the other multiverse forever because of the rapid development of the universe which mediates the multiverse.
Level III: Quantum Many World:
This theory states that other universes are around us! This theory developed from the theory of quantum mechanics which states that random quantum processes cause the universe to branch out with the many possibilities that occur. The fundamental difference in level I and III is the location of the universe that is the same as our universe. Level I states that the same universe as our universe is outside the horizon, while level III says the universe is the same as the universe
