Multiverse, Parallel Universes and Realities – a Theoretical Analysis

"Multiverse" or "metaverse" is a hypothetical set of many possible universes, including our universe, which together make up the entire physical reality. Various universes within a multiverse are called "parallel universes ". The structure of the multiverse, the nature of every universe within it, and the relationship between the various constituent universes depend on the specificity of the multiverse hypothesis under consideration. In this regard, "parallel universes" are also called alternate universes, quantum universes, parallel worlds, or alternate and parallel realities.

The Multiverse is a hypothetical set of finite and infinite possible universes, including our universe in which we live and manifest our reality. Taken together, these universes contain everything that exists: the integrity of space, time, matter, energy, and the physical laws and constants that describe them. Of the many worlds, possible evidence and interpretations follow, physicists and mathematicians are focused on in-depth study of the effects of the theory. Also, these mind journeys suggest and imply that there are parallel universes coequal to our own, and we cohabit with them in the so-called "hyperspace" that makes up our multiverse.

In physics and cosmology, parallel universes are a hypothetical collection of identical or different universes, including unique and hypothetical universes that coexist with our known universe, but can develop and exist under radically different laws of physics.

A "Parallel Universe" is a hypothetical autonomous reality, accompanied by a well-studied universe of ours. A typical and deeply specific group of parallel universes is called "multiverse", although this term can be used to describe the possible parallel universes that represent reality. While the terms "parallel universe" and "alternative reality" are generally synonymous and can be used interchangeably in most cases, sometimes there is an additional connotation to the term "alternative reality", which means that reality is a variant of our own one. The term "parallel universe" is more generally accepted without any connotations implying a connection or lack of connection with our own universe.

A universe where the laws of nature are different - for example, a universe in which there are no laws of movement - would in general be a parallel universe, but not an alternative reality and a conception between the two possibilities of a fantasy world and our reality. Physicists refer to this phantom theory as the theory of everything. Quantum physicists believe they are on the verge of finding this to be the ultimate theory. But another field of physics is convinced that the quantum level is not the minisculest level, hence it can not present and provide a theory of everything. The theory permits the existence of many other parallel universes where the laws of nature are slightly different from ours and are described by different type of equations.

Traveling to other universes
From a theoretical point of view, traveling across dimensions to other universes is possible, but the limitations arise from the amount of energy required to accomplish this task. Although this is a huge obstacle for us, there may be civilizations that can harvest energy from antimatter and travel to other universes - and one of these universes may be ours. But such a journey to other universes with different physical laws of nature can create some limitations for universal cosmic travelers and mess up their plans.

While it is theoretically possible to travel through hyperspace, the amount of energy required to do this is currently beyond our technology. For example, a huge amount of electron volts of energy is required in order to simply move into hyperspace. At the very beginning, when the big bang created our universe, some theoretical physicists believe that a mirror universe, which is a universe reverse to ours, was also created, where time moves in the opposite direction. From our view point and position in space, time in a parallel universe moves backwards. However, two distinct groups of prominent physicists are working on multiverse models that examine the initial conditions which may have created the arrow and the main direction of time, and apparently want to demonstrate that in these universes, time is moving in two different directions. A parallel mirror world may exist that may have the same physics of particles as the observable universe that connect only gravitationally.

Seeking the boundaries of nucleosynthesis in the mirror universe means that the mirror realm should have a lower temperature than usual. Therefore, the evolution of the mirror universe must deviate significantly from standard cosmology, as far as it is crucial. For the development of this mirror world, parallel to ours, great importance is attached to epochs such as baryogenesis and nucleosynthesis. Starting from an inflationary scenario that could explain the different initial phases of the two realms, the history and time of the early mirror universe have been studied. Mirror universes can provide a significant contribution to the energy density of the multiverse, and thus they could represent the corresponding component of dark matter and dark energy in the composition of a mirror universe. Unfortunately, we can not exchange information with physicists living in the mirror universe and combine our observations.

First and foremost, if both worlds have the same microphysics described by quantum interactions, life should also be possible in the mirror realm. However, there can not be too many opportunities to facilitate the cosmological scenario of the two parallel worlds with future high precision data regarding the large scale in the structure of the observable mirror universe. In fact, M-theory allows for many different interior spaces - different universes, each with its own special set of laws of nature. An opportunity exists to form a universe that will squeeze matter through gravity into our universe through some of its local laws of nature. The theory can explain the effect of dark matter, where areas of the universe are heavier.

Following the theory, the problems surrounding the big bang are replaced by an infinite space cycle, where dark energy is no longer a mysterious unknown value, but rather the extra gravitational force itself that moves the universe towards a universe or causes a membrane -membrane interaction. Dark matter would not fall into dense gravitational wells because it would be blurred by the physical distance between the various universes and by the fact that stars and galaxies would not exist at exactly the same place in every universe. Matter in multiple parallel universes must hold together and evolve on a large scale, but only part of their gravity will reach our universe.

Black Holes and Gravity Leaks into Other Universes
If a large mass of dark matter appears in massive universes measured by its inertia and the subsequent measurement of its gravity, it will be a good indicator that leakage of gravity into other universes is at hand. In the event that this discrepancy between inertia and gravity is not observed, then it is more likely that an invisible significance in the interactions in our universe exists. If dark matter is the outer membrane of every universe, then gravity will have to pass through two membranes, embracing each membrane universe, thus creating a double layer of dark matter and eventually dark energy. There will be no communication between the two universes except for the gravitational pull of our parallel sister universe that can overcome the small difference.

Given that the two universes are surrounded by dark membranes, independently forming membrane universes, we can expect the two membranes to have different properties, just as universes contain and possess qualities quite different from those in our universe. This puts on the stage at least two different types of dark matter across researches, each forming a membrane encapsulated and matched in the given universe.

Membrane Theory of Universes
The Membrane Theory can provide an explanation for weak gravity. However, this idea requires that at least one of the additional dimensions should be very large compared to a certain scale. It can be shown that in the absence of energy, gravity will be localized in a membrane and will behave exactly as predicted by the general theory of relativity. However, with sufficiently high energy, gravity will no longer be located in the membrane, and in the higher dimensions it will behave in a way that incorporates dramatic changes in gravitational dynamics. Attempts have been made to visualize the intersection of two membranes passing through any other area, actually creating our space, as they do it in reality.

Separate universes manifest, interact and participate in each membrane, their penetration is assumed through the gravity leak. Possible interpretations have been proven with regard to the numerous worlds; physicists and mathematicians are focused on studying the theory in-depth. However, the resulting theoretical picture of the numerous worlds is not only a theory that attempts to explain the multiverse. Neither is it the only option that suggests that there are universes, parallel to our own.
