Parallel universes also known as meta-universes or multiverses, are a group of theoretical twin universes that co-exist at the same time as our own. A parallel universe or alternative universe is also a hypothetical self-contained separate reality co-existing with one’s own. The term “Parallel universe” is more general, without any implications involving a relationship, or lack of relationship, with our own universe. Parallel universes are conceptualized to be simple variations of our reality, all running at the same time in different realties. Parallel universes are not exclusively restricted to the science fiction kingdom anymore. Philosophy, physics and even theology have theories about why meta-universes exist and how they operate. Parallel universes have often been used in fiction and television programs as a justification for this eccentric phenomena.

 

What is the History of parallel universe?

Since the full acceptance of Quantum mechanics, in 1956, the science that looks for explanations to phenomena that cannot be explained by the regular laws of physics and science, scientists have been hypothesizing the existence of parallel universes. American physicist Hugh Everett first formulated the idea of parallel universes to explain the theory that every possible conclusion of every choice we have actually does happen. In this universe one may choose path A, but in a parallel universe the same person may choose path B as an alternate, and so on and so forth leading to the existence of different universes based on the different possible choices. These all universes will co-exist at the same time and in probably the same space

 

What is the idea of Science fiction writers?

For years, Parallel universes were a staple of the Twilight Zone. Science fiction writers loved to hypothesize on the possible other universes which might exist. In one, they said, British Empire might still be continuing strong. Serious scientists dismissed all this as ridiculous. But now, it seems the speculation wasn’t impractical enough. Parallel universes really do exist and they are much stranger than even the science fiction writers have the mental fortitude to imagine / accept.

 

What is the justification of the Scientists for Parallel universes?

It all happened with the advent of Super string theory, hyper space, and dark matter, which made physicists realize that the 3 dimensions we thought described the universe were not enough. String theory smoothens out the mathematical contradictions that currently exist between Quantum mechanics and the Einstein’s theory of relativity. There are actually very small strings, that vibrate in 10 or 11 dimensions that we can’t see, that make up all particles and in essence all matter as we perceive it. If such Strings do exist, that could explain literally everything in the universe - from subatomic particles to the laws of speed and gravity. By the time, they are done they would come to the conclusion that our universe is just one bubble among an infinite number of membranous bubbles which moves as they wobble through the 11 dimensions.

 

If we imagine what might happen if 2 such bubble universes touch each other. Neil Turok from Cambridge, Burt Ovrut from the University of Pennsylvania and Paul Steinhardt from Princeton believe that has happened. So, the end result is that a very big bang or indeed a new universe was born - which is our Universe. This notion has shocked the whole scientific community. It turns the Conventional Big Bang theory on its head. It may be that the Big Bang wasn’t actually the beginning of everything after all. Time and space all existed before it. Indeed, Big Bangs can occur all the time.

 

What is the final word on parallel universes?

This extra-ordinary tale about the origin of our Universe has one frightening connotation. If a collision started our universe, could it happen again? Anything is possible in this extra-dimensional outer space. Possibly, there is another universe heading directly towards us, out there in space. It may perhaps only be a matter of time before we collide.
