Multiverse.
The Multiverse (or Meta-Universe) is the hypothetical set of infinite or finite possible Universes (including the Universe we consistently experience) that together comprise everything that exists: the entirety of Space, Time, Matter, and Energy as well as the Physical Laws and Constants that describe them. The various Universes within the Multiverse are sometimes called “Parallel Universes” or “Alternate Universes”.
Here are the five most plausible scientific theories suggesting we live in a Multiverse:
1. Infinite Universes
Scientists can’t be sure what the shape of space-time is, but most likely, it’s flat (as opposed to spherical shape) and stretches out infinitely. But if space-time goes on forever, then it must start repeating at some point, because there are a finite number of ways particles can be arranged in space and time. So if you look far enough, you would encounter another version of you - in fact, infinite versions of you. Some of these twins will be doing exactly what you’re doing right now, while others will have worn a different sweater this morning, and still others will have made vastly different career and life choices. Because the observable universe extends only as far as light has had a chance to get in the 13.7 billion years since the Big Bang (that would be 13.7 billion light-years), the space-time beyond that distance can be considered to be its own separate universe. In this way, a multitude of universes exists next to each other in a giant patchwork quilt of universes.
2. Bubble Universes
Other universes could arise from a theory called “eternal inflation.” Inflation is the notion that the universe expanded rapidly after the Big Bang, in effect inflating like a balloon. Eternal inflation suggests that some pockets of space stop inflating, while other regions continue to inflate, thus giving rise to many isolated “bubble universes.” Thus, our own universe, where inflation has ended, allowing stars and galaxies to form, is but a small bubble in a vast sea of space, some of which is still inflating, that contains many other bubbles like ours.
3. Parallel Universes
Another idea that arises from string theory is the notion of “braneworlds” - parallel universes. The idea comes from the possibility of many more dimensions to our world than the three of space and one of time that we know. In addition to our own three-dimensional “brane” of space, other three-dimensional branes may float in a higher-dimensional space. Our universe is one of potentially numerous ‘slabs’ floating in a higher-dimensional space. These brane universes aren’t always parallel and out of reach. Sometimes, they might slam into each other, causing repeated Big Bangs that reset the universes over and over again.
4. Daughter Universes
Quantum mechanics describes the world in terms of probabilities, rather than definite outcomes. And the mathematics of this theory might suggest that all possible outcomes of a situation do occur - in their own separate universes. For example, if you reach a crossroads where you can go right or left, the present universe gives rise to two daughter universes: one in which you go right, and one in which you go left. And in each universe, there’s a copy of you witnessing one or the other outcome, thinking - incorrectly - that your reality is the only reality.
5. Mathematical Universes
Scientists have debated whether mathematics is simply a useful tool for describing the universe, or whether math itself is the fundamental reality, and our observations of the universe are just imperfect perceptions of its true mathematical nature. If the latter is the case, then perhaps the particular mathematical structure that makes up our universe isn’t the only option, and in fact all possible mathematical structures exist as their own separate universes.
