Parallel Universe : We might be living in an alternate reality!

Do you believe in Alternate Realities?

Multiverses are all over the place. 

Films, mainstream science articles, philosophical discussions, Family Guy episodes. 

At some time, we've all been welcome to envision duplicates of ourselves going around in some other dimension, carrying on with their lives however not exactly identical to our own. 

Yet, why do people think that parallel universe exists in the first place?

What is a Parallel Universe?

An parallel universe is referred to by different terms, for example, alternate universe, alternate reality or an alternate dimension however they all mean the equivalent, which is, a theoretical universe where life exists past our own universe. It basically says that there are different universes out there where life and "astronomical objects" exist simply as they do in our universe.

There are a couple of various speculations about the presence of these different universes. Two that researchers talk about a lot. The primary, gone ahead by a person named Hugh Everett during the 1950s, is known as the "Many-Worlds Interpretation of Quantum Mechanics" and basically says that at whatever point there are various ways an event could turn out, the world "parts" into new universes to oblige every conceivable result. This has some pretty amusing implications. Take yourself, for instance. Many-worlds theory says that you split like an Amoeba each time another world is made, permitting a duplicate of you to go ahead in the recently made equal world while you stay in our reality, uninformed that a split has occurred.

There are many other theories like this about parallel universe, some of them that I found interesting and convincing are:

The Anti Matter Theory

We all were taught at schools and colleges that electrons and protons have negative and positive charge, openly yet in 1955 two researchers named Emilo Segre and Owen Chamberlain found something many refer to as antimatter which is matter yet made out of certain electrons and negative protons. Since the revelation of antimatter, we have had the option to make antimatter in the research facilities and study their properties. Strikingly an antimatter acts the same way as matters but on collision they obliterate each other, leaving behind only energy. 

Now here is where things become intriguing. When the universe evolved, it ought to have made equal amount of matter and antimatter and in the following couple of moments of the origin of the universe, matter and antimatter would have collided vanishing and leaving absolutely nothing. But after thirteen billion years, all the universe is made out of matter so where did all the antimatter go? Consider the possibility that after the big bang, a force, like repulsion, would have prevented matter and antimatter colliding prompting the antimatter framing a totally unique and its own universe where people just like us would be questioning the presence of matter. Where humans just like us would be studying the same physics class however a different chemistry one!

Bubble Universes

Quantum mechanics states, there is no such thing as an empty space. Even the most perfect vacuum is actually filled with particles and antiparticles, which flare into existence and almost instantaneously fade back into nothingness. The reason why we can't observe them is that they don't last enough to be perceived, but we know they do exist because of their effects. 

When quantum theory is applied to space at the smallest possible scale, space becomes unstable. Rather than remaining perfectly smooth and continuous, space and time destabilize, churning and frothing into a foam of space-time bubbles. If space and time are quantized, they can fluctuate. So you can create virtual space-times just as you can create virtual particles.

Put differently it means that it is not just particles and antiparticles that can snap in and out of nothingness: bubbles of space-time can do the same. And since then this bubble has evolved into billions of galaxies giving birth to planets, stars and other cosmological bodies. Now if this is the answer to the ultimate question of why is there anything instead of nothing then the multiple bubbles of the universe should have been created. It is highly probable that we are living in a sea of bubbles of universes!

How parallel universe is a solution to many problems

Discovery of parallel universes can completely revolutionize our understanding of life and can provide answers to century old problems and questions.

The paradoxes of time: Time travel leads to multiple time travel paradoxes which can easily be resolved with the “entangled spaces” theory. Paradoxes like the “grandfather paradox” which says that if a person travels to a time before their grandfather had children and kills him making their own birth impossible. So how was he able to move back in time in the first place? If the theory of entangled spaces held true then they can resolve this mind melting problem by just reasoning that when you go back in time to kill your grandfather, you’re not going back to your own history, but a copy of your history, and everything you do in this version of your history will affect the alternate future of that universe, not your own. It is the universe where your grandfather was dead, and it would not affect the timeline you are living in.

The ultimate question of existence: The ultimate question of existence which is why is there anything instead of nothing can be resolved by the “bubble universes” theory stating that space and time popped out of nothingness creating bubbles of universes which we inhabit.

Many would find the idea of a parallel universe too fascinating and unreal but as science is expanding day by day we are realizing that this idea might actually be real. Many theories like string theory only work if we include different universes, even successful theories like the expansive universe say the same. In addition, a recent research by NASA found few abnormalities in the data which could only be sufficed by the idea that parallel universes do exist which could perhaps also aid in alternate universe discovery. Even though we are miles away from finding real hard proof; we strongly believe that our universe might just not be alone and discovery of the same could bring a complete revolution in everything we know.
