The True Science of Parallel Universes

You probably live in a parallel universe. Here’s why.

These universes are all related to ours; indeed, they branch off from ours, and our universe is branched off of others. Within these parallel universes, our wars have had different outcomes than the ones we know. Species that are extinct in our universe have evolved and adapted in others. In other universes, we humans may have become extinct. This thought boggles the mind and yet, it is still comprehensible. Notions of parallel universes or dimensions that resemble our own have appeared in works of science fiction and have been used as explanations for metaphysics.

The multiverse , [1] also known as a maniverse, megaverse, metaverse, omniverse, or meta-universe , is a hypothetical group of multiple universes. Together, these universes comprise everything that exists: the entirety of space , time , matter , energy , and the physical laws and constants that describe them. He said that when his equations seemed to describe several different histories, these were "not alternatives, but all really happen simultaneously". The American philosopher and psychologist William James used the term "multiverse" in , but in a different context. Multiple universes have been hypothesized in cosmology , physics , astronomy , religion , philosophy , transpersonal psychology , Music and all kinds of literature , particularly in science fiction , Comic books and fantasy.

Is our universe unique? From science fiction to science fact, there is a concept that suggests that there could be other universes besides our own, where all the choices you made in this life played out in alternate realities. The concept is known as a "parallel universe," and is a facet of the astronomical theory of the multiverse. The idea is pervasive in comic books, video games, television and movies. A fuller list of parallel universes in fiction is at the bottom of the article. There actually is quite a bit of evidence out there for a multiverse.

Movies, popular science articles, philosophical debates, Family Guy episodes. But why do people think multiverses exist in the first place?

Arguing for a multiverse

A few months before physicist Stephen Hawking died, he published a paper that several media outlets touted as a way to finally prove or disprove the existence of parallel worlds. It's not entirely uninteresting, but it's one of literally several thousand ideas for what might possibly have happened in the early universe" many of which include parallel worlds, said Sabine Hossenfelder, a physicist at the Frankfurt Institute for Advanced Studies in Germany, who blogs at backreaction.

We can imagine a very large number of possible outcomes that could have resulted from the conditions our Universe was born with. It is possible, if there were enough chances, that this could occur many times, leading to a scenario that we think of as "infinite parallel Universes" that contain all possible outcomes, including the roads our Universe didn't travel. You've likely imagined it before: another Universe out there, just like this one, where all the random events and chances that brought about our reality exactly as it is played out just the same. Except right now, when you made one fateful decision in this Universe, you took an alternate path in this other Universe. These two Universes, which ran parallel to one another for so long, suddenly diverge.

In , a Princeton physics graduate student named Hugh Everett showed that the consistency of quantum mechanics required the existence of an infinity of universes parallel to our universe. That is, there has to be a person identical to you reading this identical article right now in a universe identical to ours. Further, there have to be an infinite number of universes, and thus an infinite number of people identical to you in them. Yet few people have even heard of the parallel universes, or thought about the philosophical and ethical implications of their existence. The free will question arises because the equations of physics are deterministic.

  1. Originating in the s, the many-worlds theory posits that parallel worlds constantly branch off from each other, moment by moment.
