Does Parallel Universe Exist?


Everyone has a choice to make throughout their life. Some of you perhaps wanted to work after school to ease the burden of your parents for raising you up, maybe a fashion model, or an IT technician, or you may even create a new invention through computer application to ease the society just like the invention of smartphones. Well, frankly speaking, you may have not achieved your dream in this universe as you are just a student, and a college lecturer, but you may do, in another universe, or in another words, a parallel universe.
   Parallel universe or known as the many world interpretation is a philosophy of quantum mechanics that implies that there are another universe exist besides our own with different histories, where all your life choice you made in this world, will be played differently in another universe, overall, everything known as multiverse. Originally develop by Niel Bohrs and Werner Heisenberg through Coppenhagen Interpretation Paradox and being hypothesized in physics, religion, cosmology, astronomy and philosophy and eventually it spuns into numerous science fiction series and media and such as Star Trek and Clannad anime series. The parallel universe also known in other context as parallel timeline, alternate history, multiverse, quantum realities, and parallel world.


The model of multiverse. Each universe consist of thousands of galaxies.

   Before the theory being develop, reality is viewed as a single history just like a straight line. With multiverse theory, the reality said to be start of as a single line and branches off into multiple realities with every possible outcomes of an events results in many alternate histories emerged in another universe.

History


One of the famous thought experiment regarding the parallel universe is Schrödinger's cat theory developed by Erwin Schrodinger. He proposed that when a cat being locked in the steel chamber with a hammer, poison, radioactive material and geiger counter, where the cat's life and death depends on the radioactivity material ; the geiger counter will detect the radioactive material, the hammer would smash the poison and thus killing the cat. Until the box is open, the cat may be either dead or alive.

   As nonsensical as it seems, the condition of the cat split into two outcomes according to the parallel universe theory. In this universe, the cat might have died due to the poison, but the cat might also alive somewhere in a parallel universe with different law of physic applied.

The condition of the cat split into two outcomes according to the Schrodinger's cat theory.




The Evidence

One theory suggest that every human beings and animals are able to make an interdimensional journey through dreams. Reality perceived as the world that we are currently live in, while the dreams are the 'Butterfly Effect' that people encountered when we make a different choice in our life, which explains our intense emotion and familiarity during the dream experience. For example, you may have dream about your ex lover, the romantic dates, et cetera, but in fact, you don't have any lover yet in your waking life. The nostalgic feels and the familiar scene might be happen in an alternate reality. This is because you have connect to your other self in another universe; there may be two of you, and even thousands to infinite numbers of you outside this universe that you live in, living in a different life.






   In 2010, Stephen M. Feeney analyzed Wilkinson Microwave Anisotropy Probe (WMAP) data and suggest that our universe may have collided with another universe in the distant past, although there are no significant evidence such as bubble universe collision nor gravitational pull from our universe to the other universe.



The Models of Parallel Universe


What if? The simplest way to transport yourself to a parallel world is to imagine how you, yourself might all the ways might have turned out differently if you make a different life choice. All of these alternate realities represents a parallel universe. The mathematician Gottfried Leibniz states that we are living in the “best of all possible worlds” and that all these remained unnoticed from our own universe. Contemporary physicists who proposed the Anthropic Principle argue that if the universe’s conditions were slightly different in terms of law of physics, it couldn’t have supported intelligent life, and we may not be here today to speculate more about it. 

There could be infinite amount of you in another universe.

Alternative realities made possible by time travel: The time travel term were popularized by science fiction writers, although Einstein’s general theory of relativity is the sources of the possibility of time travel. The theory of relativity distinguish relationship between space and time and hypothetically permits travels to the past, though the mechanics of such a journey are still largely beyond our ability. Also, the journey to future where made possible when the strength of gravitational force enhanced thus, a wormhole is created, and caused time dilation; a minute in the strong gravitational field, may be a month on Earth. In recent decades, the ideas of travelling the time backward published in reputable physics journals. If it is possible possible, what would happen if we attempt to changed history? Will a new timeline emerge as a new universe, where the chain of events was different from the default timeline? 
Copycat regions of the universe: We are now being turn from a small to the incomprehensibly large universe. If the universe is infinite, as many cosmologists proposed, then if you travel far enough you may reach some regions nearly identical to ours.  If you take a certain number of elements and mix them into an infinite number of combinations, eventually chance will reproduce one of the previous arrangements. Hence, by chance, there might be a parallel Earth where a nearly-identical version of you is reading this article using a different device from laptop and smartphone.


Bubble Universes and Baby Universes: In general relativity, an energy field of the right proportion can caused space to grow extremely large. This phenomenon  explain why the universe expanded rapidly during the inflationary era. However, they’ve come to realize that if explosive expansion took place in one part of space, it probably happened elsewhere, too. Thus, myriad bubble universes could have emerged from the cosmic sea of energy. Baby universes is just an idea developed by cosmologist, in which universes could be placed in the extreme conditions of black holes. In other words, the universe itself may be a living beings, while the planets, galaxies and life forms, are functioned as a 'cells' to the universe.
