What is a parallel universe? Does it exist like our universe? Are there any living creatures in that universe? Is the mirror dimension also real? Well, we will answer the answers to all these mysterious questions; let’s see as we proceed.
Parallel universes have become more common than just a plot device in science fiction. Various scientific hypotheses now lend credence to the notion of parallel universes to our own. The multiverse theory is still one of the most debatable concepts in science, though.
The size of our cosmos is unfathomable. There are hundreds of billions or trillions of galaxies that contain billions or trillions of stars that are spinning across space. According to some scientists who are researching cosmological models, the cosmos may be 7 billion light-years large. Others believe it might be endless.
The concept of a parallel universe and the idea that we might live just one of an endless number of possible lifetimes are favourites in science fiction. However, multiverses are only present in “Star Trek,” “Spiderman,” “Doctor Strange: Multiverse of Madness,” and “Doctor Who.”
Real scientific theory investigates the possibility of parallel or hidden worlds far away from but mirror our own and, in some circumstances, support it. Arguments about parallel universes and multiverses are frequently made with other important scientific theories, including the Big Bang, string theory, and quantum physics.
The Big Bang Theory, Parallel Universes, and Eternal Inflation
Everything we can currently understand was an infinitesimal singularity 13.7 billion years ago. According to the Big Bang theory, it suddenly erupted, expanding faster than the speed of light for a brief moment in all directions.
The process known as cosmic inflation caused the universe to expand outward to 1026 times its original size in less than 10-32 seconds. All of this occurred before the real expansion of matter that we typically associate with the Big Bang, which was a result of all this inflation: a torrent of matter and radiation appeared when inflation slowed, producing the iconic Big Bang fireball, and started to form the atoms, molecules, stars, and galaxies that fill the universe today.
Some scientists now believe that the existence of numerous universes is plausible or perhaps quite likely due to the enigmatic processes of inflation and the Big Bang. According to theoretical physicist Alexander Vilenkin of Tufts University in Massachusetts, inflation did not halt globally at the same moment.
Cosmic inflation may have ended for Earth-related evidence 13.8 billion years ago, but it is still occurring in other locations. The theory of eternal inflation is what is meant by this. Vilenkin wrote for Scientific American in 2011 that as inflation ends in a certain location, a new bubble universe emerges.
However, even if humans were to make it to the next bubble, perpetual inflation (coupled with string theory) suggests that our familiar universe, with its physical constants and conducive environment, may be very different from the fictional bubble universe next to our own.
According to Vilenkin’s theory, there might be other intelligent observers in some of the infinite bubble universes that exist outside our own. But as time goes on, we move further away from them, and our paths will never cross.
Are Parallel Universes and Multiverses Real?
Of course, there are other unknowns linked with this inflationary scenario. We don’t know how long inflation occurred before it ended, causing the Big Bang, or whether it was short, long, or infinite. We don’t know if the places where inflation halted are identical, with the same natural laws, fundamental constants, quantum characteristics, and variations as our reality. And we do not know if these multiple Universes are physically related in some manner or if they follow their own rules and have no effect on one another.
After all, the idea of parallel Universes is that the many-worlds interpretation of quantum mechanics will provide a place for all of those various realities — where we made different decisions, and different consequences were obtained — to reside genuinely.
Is it possible that there is another Universe in which everything happened as it did in this one? Still, you did one tiny thing differently, so your life turned out dramatically different.
Maybe. To believe such is wishful thinking. But, for that to be our physical reality, the unknowns about our universe must have particular answers, which may not be very likely.
The Parallel Universe and Quantum Physics
Several researchers base their theories on quantum mechanics, the mathematical representation of subatomic particles. Multiple states of reality for microscopic particles are all feasible simultaneously in quantum mechanics – a “wave function” contains all those probabilities.
When we look, though, we only see one of the alternatives. According to the Stanford Encyclopedia of Philosophy’s Copenhagen interpretation of quantum mechanics, we experience a result when the quantum state “collapses” into a single reality.
According to the many-world theory, a distinct quantum consequence becomes a reality in another “world” every time one state or outcome is detected. It is a branching structure in which our perception of the cosmos splits into practically endless choices, instant by instant.
While there may be countless versions of you living lives that are slightly — or drastically — different from your existence in this world, you’d never know it since those parallel worlds are wholly independent and unable to connect.
Some scientists believe in a simplified model of numerous universes. If the cosmos we live in continues indefinitely, the building elements of matter can only organize themselves in so many different ways as they assemble across limitless space.
Any finite set of particle types must eventually reproduce a particular arrangement. In a large enough space, the particles must theoretically replicate arrangements as massive as whole solar systems and galaxies.
So your entire existence, from what you ate for breakfast yesterday, may be replicated somewhere in the universe. That is, at least, the theory.
Is Mirror Dimension the Same Thing As the Parallel Universe?
Many current scientists believe there is a mirror copy of our universe, and they are working on an explanation for its ramifications known as the Mirror Image Theory.
Have you ever observed that everything in the mirror is the same but has been horizontally reversed such that left and right appear to be inverted? Asymmetric items demonstrate that a mirror or a body of water does not reverse images from left to right or vice versa but rather from front to rear. The term “mirror image,” which refers to two similar entities, might describe the entire cosmos.
Experts from the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, have postulated that the universe originated with the Big Bang — and that on the opposing side of the Big Bang timeline, stretching backwards in time, a universe that was the exact mirror copy of our own once existed.
Instead of claiming that there was another universe before the bang, we propose that the existence before the explosion is, in some respects, a projection of the cosmos after the bang, according to Perimeter Institute researcher Neil Turok.
Everything, including protons, electrons, and even operations like breaking an egg, would be inverted. Atoms would be made of antiprotons and positively charged electrons, while eggs would not crack and return to chickens. That universe would eventually contract, possibly to a singularity, and then enlarge into our own.
Another way to look at it is that two worlds were generated at the Big Bang and simultaneously erupted forth and backwards in time. The mirror verse idea may be able to shed light on dark matter, another enigma that is straining our knowledge of the cosmos. To test that theory, the researchers will conduct an experiment in which neutrons are directed against an impenetrable wall.
It is difficult for our scientists to explain why there is so much dark matter in our world but that it cannot be directly observed or measured or where all the missing baryonic matter in our universe is.
However, suppose the Mirror Image Theory is correct. In that case, it is hilarious to imagine that there may be researchers in the mirror verse attempting to determine why their dark matter is significantly less than it ought to be.
Objections Regarding Multiple Dimensions and Parallel Universes
When there are many theories and explanations in favour of the existence of a parallel world and mirror dimension, there are also some arguments which make the theories somehow difficult to believe. But the experts and scientists work on disbelieving these theories.
We will never be able to test multiverse theories. If there is no way to refute the theories, should they even be believed since we will never be able to look beyond the observable universe?
Simple concepts can occasionally be the best. Some scientists contend that the multiverse theory is unnecessary; it merely causes complexities and doesn’t resolve any dilemmas.
Lack of Proof
We cannot only prove any multiverse theory; we cannot even refute it. There is no evidence yet supporting the existence of several universes; instead, what we can currently observe points to only one: our own.
Parallel Universes in the World of Fiction
Several works of fantasy and fiction are inspired by the concepts of multiple worlds and the multiverse. Overlapping realms emerge in Greek myth, along with Buddhist and Hindu cosmology.
The concept of several universes colliding first appeared in print in Edwin A. Abbott’s novella “Flatland: A Romance of Many Dimensions” (Seeley & Co., 1884), and it can still be seen in current films like the 2016 Marvel picture “Doctor Strange.”
As stated by the New York Public Library, the central theme of the isekai subgenre of Japanese fantasy novels is characters who have been transported to alternate worlds. Almost every “Star Trek” series includes some mirror universe. The 2009 reboot film starring Chris Pine and Zachary Quinto immersed following “Star Trek” films in an entirely new timeline that openly departs from the original series.
And comic books, as well as their film adaptations, dive deeply into the concept of a parallel universe. Recent Marvel Comics (film and print) arcs, DC’s Flashpoint arc, and 2018’s “Into the Spider-Verse” all explore numerous universes and their interconnections.
The concepts of rarity and uniqueness are rendered ineffective in the other world theories that scientists have proposed. The logical conclusion of endless possibilities led to the creation of our solar system, Earth, and life itself.
Consider the basic physics constants we have learned to understand and measure, such as the gravitational force, the mass of electrons, and the speed of light. There are 26 dimensionless constants that scientists have identified and assigned values to with arbitrary units. However, how did these constants initially get to be constants?
When the universe began within a multiverse frame, it divided into numerous parallel worlds, each of which had its unique set of fundamental constants and values.
The fundamental forces are absent, stronger, weaker, etc., in other copies of our universe. Contrary to our universe, which was found suitable for life to originate, the established conditions in the bulk of these parallel universes are not favourable enough for life to exist.
If our universe is one of many, and you are one of many, you should be more conscious of your choices and deeds. Every decision you make and action you do results in the occurrence of all other conceivable choices and acts, each of which creates a parallel universe. What you do here affects your life and the lives of your other selves throughout the multiverse.
