We probably inhabit one of the worlds of the multiverse, offer an interesting view of the reality of theoretical physicists. It turns out that we live in a universe that is most likely not the only one of its kind. In fact, the Unlimited Universe for us may represent only one world out of an unlimited number of worlds that make up the "multiverse".
Of course, the fascinating concept causes some distrust, it has proven physical data behind it. In addition, there are several ways of leading to the conclusion about the existence of the multiverse - this is independently assured by several theorists.
In fact, experts are more inclined towards the fact of the existence of unobservable universes than their absence. We will never see them, and are unlikely to go there, according to theoretical researchers of spaces. At least as of today, no way is known to travel to the hidden universes.
Below is a list of five incredible theories, yet giving us the certainty that we only inhabit one world from the many layers of the multiverse.
INFINITE UNIVERSES
Of course, no one today can confidently imagine the structure of space-time, but, most likely, it has a shape stretched to an indefinite distance. If the concept of space-time is eternity, then at some point it begins to repeat itself, since the number of options for organizing particles in space-time is limited.
If you look at the problem from a distance, you can see the "variations" of oneself, in fact, an unlimited number of options for one's own individuality. Some of the "twins" will be busy with what you are at the moment, the second, for example, will dress differently, and the third will make a different decision, etc.

Since the observable Universe stretches only the distance that light has been able to cover since the Big Bang (the day our Universe was formed), then space-time outside this path can be considered an independent Universe. Thus, in the colossal mishmash of the universe, there is an unlimited number of universes.
BUBBLE UNIVERSES
Beyond the proposed indefinite number of universes, organized by the expanding matter of space-time, individual objects can become the fruit of the action of the so-called "theory of infinite bloating."
The essence of the "bloating" theory boils down to the rapid expansion of the Universe after the Big Bang, resembling a balloon as a result of an event. Infinite Bloating, proposed by the Tufts University cosmologist, reports that some "pockets" of space stop expanding, while other regions continue to expand, creating many isolated "bubble universes."
PARALLEL UNIVERSES
Another elegant consideration is singled out from string theory - the idea of "membrane worlds" - parallel universes out of our reach. Scientists from the Institute of Theoretical Physics (Ontario, Canada) at Princeton University became the authors of an interesting theory that is actively used in many hypotheses (up to aliens).
The idea brought by scientists comes from the possibility of the existence of more dimensions, known to us as three spatial and one temporal. In addition to our three "membrane" spatial dimensions, there may be three more dimensions in the cosmic spheres.
SUBSIDIARY UNIVERSES
The application of the theoretical conclusions of quantum mechanics, which describes the tiny world of subatomic particles, provides another option for the formation of multiple universes. True, quantum mechanics portrays the world in terms of probabilities, not definite outcomes.
The model of the proposed theory does not insist, but says that all possible variants of a certain situation will come true - in their own independent universes.
For example, you are standing at an intersection with two options - left and right. Depending on your step, the existing universe will split into two options, in accordance with the chosen direction.
MATHEMATICAL UNIVERSES
There is still an ongoing debate among theorists about whether mathematics is a wonderful tool for understanding and understanding the universe. Or maybe mathematics is a fundamental reality, and all our observations are simply imperfect sensations of its true mathematical nature?
If the latter observation is correct, then a certain mathematical structure underlying our universe is not the only option.
In fact, all possible mathematical structures live in the form of separate universes. "Mathematical structure is a concept that can be described completely independently of human understanding," says the author of this dizzying idea. "I really believe that this universe can exist independently of me, and it will continue to exist even in the absence of humanity."
