WHAT IS A PARALLEL WORLD?
Parallel universes, also called meta-universes or multiuniverses, are a group of theoretical twin universes that exist and take place at the same time as our universe. The parallel world is said to be a variation of our reality, so all things take place at the same time but with different realities. The idea of a parallel world is not confined to the realm of science fiction alone; Philosophy, physics, and even theology have their own explanations as to why there is a parallel world and how the parallel world works. The parallel world is often used in fictional stories or television shows to explain the occurrence of strange phenomena.
Quantum mechanics, a science that seeks to explain phenomena unexplained by the laws of physics and classical natural law, has been examining parallel worlds since 1956. American physicist Hugh Everett first formulated the idea of a parallel world to explain the theory that every possibility Of every choice taken actually did happen. If in this universe you choose path A, your other will choose path B in parallel world.
The most heated argument is about where and how the parallel world is. Some experts say that meta-universes are close to our world. So close that the ghosts we see are probably none other than those of the parallel world who are somehow strayed into our reality. Other postulates say that the parallel world is far beyond the farthest galaxy. The third theory says that the parallel world is in a different dimension, either lower or higher than the four dimensional world we live in today.
Though the idea of a parallel world sounds overwhelming, more and more scientists believe in the idea that the double universe is very close to our lives. A surprising new theory is currently being studied at some of the world's top universities. This theory says that the Big Bang is not really the beginning of the universe. Nowadays some scientists claim that the big explosion that we have assumed as the origin of the universe may in fact be the result of a collision of two universes that then result in the emergence of a new universe. This revolutionary theory is taken seriously by the scientists of quantum mechanics and to this day has been a source of heated debate.
