What is parallel universe theory?
Parallel universe theory can be hard to wrap your head around, but it’s actually an incredibly simple concept.
Parallel universe theory basically states that every time you make a decision, there are multiple alternate universes created within the multiverse that correspond to all of the different possible outcomes of your decision.
In other words, when you decide to eat ice cream instead of pasta tonight, two separate universes are created within the multiverse, one in which you eat ice cream and one in which you eat pasta.
You could find yourself living in either of these universes depending on the outcome of your decision.

Introduction to parallel universe theory
A parallel universe is a hypothetical self-contained separate reality coexisting with one's own. The concept parallels ideas found in philosophical and scientific concepts such as alternate history, alternate reality, parallel dimensions, and alternate universes.
In physics terminology, a parallel universe is one where all physical laws take identical values to those of our universe. The idea may be summarized by paraphrasing Occam's razor: the simplest explanation tends to be correct.
Proponents suggest that considering an alternative hypothesis can lead to answers not based on unverifiable assumptions.

What are parallel universes?
Parallel universes theory are a hypothetical set of possible universes that together make up everything that exists: they contain Earths with wildly different historical events, or even other dimensions and concepts such as antimatter.
In some ways, parallel universes can be thought of as complementary to quantum mechanics; just as there is an almost infinite number of possible outcomes in quantum theory, there is also an infinite number of parallel worlds.
Some scientists say it’s plausible that we’re living in one now. Although many people often use parallel universe to describe any universe outside our own (like Star Trek's Mirror Universe), physicists prefer to call it a multiverse. According to your definition, how could you tell whether we're in a multiverse?
Why do scientists talk about the multiverse?
In order to understand parallel universe theory, it's important to first understand why scientists believe in a multiverse.
The big bang theory suggests that our universe was created by an explosion that caused everything we see around us to be hurled apart at such speeds that they've been traveling ever since.
What's more, there are indications of missing matter in space, suggesting there could be additional galaxies we can't see because they're too far away.
Could those distant stars represent a different version of our own solar system? Or what if there was another event—one other than an explosion—that created another version of Earth and its surrounding planets?
That's where parallel universe theory comes into play. Scientists talk about different versions of our own world existing as part of a multiverse.
Parallel Universes exist in many theories
The most known theory is probably String Theory in which Parallel Universes are described as Branes (short for membranes). In string theory, a brane is any of a number of possible two-dimensional extended objects.
The term brane is derived from the word membrane, because many of these objects are thought to be membranous in nature. There are five different types of branes; each describes a type of fundamental particle:
The first and simplest brane is just an extended object with no special structure. This kind of brane could be just about anything. For example, it could describe an extended string or ribbon-like object floating through space like a fishing line or even a water noodle.
The theory of cosmic inflation that underlies astronomers's actual conceptions of our cosmos predicts the existence of a multiverse - a multiverse would be with other universes identical to ours or would be totally different. Several theories explain why a multiverse is possible.
Those who choose to accept this possibility believe that in the multiverse there is the possibility of different universes, and vice versa.
Support for the theory of the multiverse focuses on the idea that there are several universes that follow the physics of quantum mechanics. The theory of the daughter universe is an idea driven by the laws of probability.
A hypothetical group of multiuniversal multiverses, also called parallel universes, other universes, alternative universes, or many worlds. There are many types of multiverse theories, the best known of which are the Many Worlds Theory (a universe in which we are all one) and the Parallel Universe (in which we take opposing measures). This is a theory in which, besides universes that are similar to our universe, there are also some that are similar to our universe but different.
The concept of a parallel universe theory is an idea that has emerged from the multiverse theory that our universe is one of many existing universes that are so to speak parallel to each other.
The Multiverse states that there are several versions of the Universe, each of which differs from the others. In theoretical physics the idea that parallel universes exist in its simplest form is that it proposes an infinite set of universes, including our own, that encompass everything that exists, including space, time, matter, energy, physical laws and observed constants.
Multiverse theories (also known as meta-universe theories) are a group of models that assume that our physical reality includes more than one universe and that there are at least one or more universes other than ours.
Some types of multiverses postulate that all the universes in the quilted multiverse we study have the same physical constant (e.g. Planck constant or speed of light, C ). Other types of the multiverse suggest that physical constants and laws may be different in different universes, as in string theory.
Combining this scenario with string theory allows for the possibility of an infinite number of universes with different compressions, additional dimensions and different physical laws.
Unlike many world theories, string theory assumes that all universes come into contact with each other.
The universes predicted by string theory and inflation live in the same physical space but since many quantum mechanics universes live in mathematical space, they may overlap or collide.
The universes predicted by string theory and inflation can collide, leaving out possible signatures in the cosmic sky that we are trying to find.
In a multiverse scenario, we know that our universe is only one of many universes that exist parallel to our own. However, we do not know the entangled properties of the various universes in the multiverse.
This image of the universe - the multiverse, as it is called - explains a long-standing mystery: a constant nature that seems to be aligned with the emergence of life.
One of the most remarkable ideas in the so-called Many-Worlds Interpretation of Quantum Mechanics is to postulate that all possible outcomes can occur and that in this universe no single outcome can occur.
One of the various models describing the different structures of physical reality is the quilted multiverse, which postsulates that all possible events can occur many times and that the nature of many universes can resemble ours.
The multiverse is a kind of uniqueness that results from the postulation of all possible events that could have occurred many times in many universes.
String theory is a theoretical explanation of reality that predicts a large number of universes with 10 to 500 or more different physical parameters.
It allows for an immense number of solutions describing bubble universes with different physical properties. It takes an infinite number of parallel universes to account for all possible outcomes but one remarkable idea - known as the "interpretation of quantum mechanics in many worlds - is more valid than any other.
To return to our universe the level I multiverse eliminates the need to set initial conditions, an upgrade to Level II eliminates the need to set physical constants, and Level IV eliminates the need to set anything at all.
The most common feature of the four multiverse levels is that the simplest and most elegant theories are bound to include parallel universes by default.
Level II bubble universes with different physical constants and effects are found in worlds that emerge in fractions of a second when spontaneous symmetry breaks in the Level III multiverse.
Type 2 parallel universes depend on two theories that have proven to be types of multiverses: the inflation model and the ecpyrotic theory. Inflation lasts a finite time, so we can say that a parallel universe based on the number of universes that increase with time and the number of possible outcomes for a single universe that increase with time is our own multiverse.
Are Parallel Universes or parallel universe theory possible?
|parallel universe theory
On the contrary, the idea that the universe may be one of infinite numbers comes from current theories such as quantum mechanics and string theory.
Some physics and astronomy theories assume that there is a multiverse consisting of many parallel universes. Multiverse theorists believe that the multiverse is the only explanation for our internal mysterious phenomena, such as the pressure of a vacuum, the size of electrons, the distribution of matter after the Big Bang and even the Big Bang.
Those who think of parallel universes believe that our universe can be just a branch of the cosmic tree that exists at the same time, just in a different state of time, a different past, and a different future.
In any case, the realms of parallel universes offer many interesting (and overwhelming) possibilities. As many authors have imagined over the years, if there are an infinite number of other universes, then at least a few of them contain your counterparts.
However, one can also agree that all of these possibilities are correct and that they exist in different universes of the multiverse. But for this to truly be our physical reality, these unknowns about our universe must have specific answers that may be unlikely.
In the multiverse scenario, the universe as we know it is only one of many universes that exist independently and simultaneously from our universe. In fact, many of the best scientific models for creating the universe actually rely on the existence of the multiverse.
The idea of the multiverse was not only introduced into society by science fiction writers, but also born from other prerequisites such as string theory and quantum mechanics. One of the versions of parallel universes that cosmologists are considering is the so-called multiverse, which is the result of the dominant theory of the origin of the universe called inflation.
The universes predicted by string theory and inflation live in the same physical space (unlike many universes of quantum mechanics that live in mathematical space), they can overlap or collide. Unlike many worlds theory, string theory suggests that these universes can be in contact with each other.
By combining this scenario with string theory, the possibility exists that each of these universes has a different densification of extra dimensions and therefore has different physical laws. What is interesting about this theory is that in other universes the laws of physics can be very different from ours, since they are not related.
Or perhaps more universes could follow quantum mechanical theory (how subatomic particles behave) as part of a "baby universe" theory. If you follow the laws of probability, this assumes that for every outcome that can result from one of your decisions, there will be a series of universes, in each of which a result was born.
If you are a supporter of the big bang of the multiverse, it means that leaving our universe to another universe is as impossible as going back to before the big bang that caused our universe. However, even if such parallel universes exist in a larger multiverse, even if their number is infinite, not all imaginable effects are possible. Therefore, even if there are astronomical numbers that may occur, including quantum interactions with a set of continuous allowable results, an infinite number of parallel universes must contain all of them.
If there are a large (possibly infinite) number of universes, each of which may have different physical laws (or different fundamental physical constants), then some of them (though few) will have a combination of fundamental laws and parameters suitable for development. Matter, astronomical structures, fundamental diversity, stars and planets that can exist long enough to give rise to life and development.
The fourth argument given in my book is that if there is an external reality completely independent of us humans, then there is a fourth multiverse that enables all mathematically possible universes. American theoretical physicist and renowned string theorist Brian Green of Columbia University argues that the rationale for multiverse travel -- assuming parallel universes do exist -- depends on which concept of multiverse you identify with.
Meanwhile, theoretical physicist Michio Kaku believes that our universe will end in a "great frost" and that one day technology will allow us to travel between universes. This may mean that the decisions we make in this universe have consequences for other versions of ourselves living in parallel worlds. If our universe collided with another, it would provide some evidence, although it is unclear if we will survive to study it.
Some scientists have suggested that there may be another universe next to ours. Many physicists have explored different types of parallel universes in recent books, including Sean Carroll, David Deutsch, Brian Green, Michio Kaku, Martin Rees, Leonard Susskind, and Alexander Vilenkin. The physics community has discussed various theories of the multiverse over time.
The answer to this question needs to be searched for probabilities that depend on knowledge of other universes, as well as many other questions. Another possible way is to explore the mathematical universe. In short, it explains that the structure of mathematics can change according to the universe you live in. This concept is called "parallel universes" and is an aspect of astronomical theory. Multiverse. This new theory suggests that all these infinite worlds overlap and occupy the same space-time region at the same time, just like quantum states.

Summary on parallel universe theory
Parallel universe theory is a hypothesis in physics and philosophy suggesting that our universe may be one of many universes that together comprise everything that exists: the multiverse. As originally proposed, it stated that for every single possible quantum outcome there exists a parallel universe. Thus, our observed universe is just one of many possibilities. In layman's terms, our reality as we perceive it could actually be an alternate version of another reality with different laws of physics entirely. This theory has been explored in various forms through books, television shows and movies like Star Trek or Avatar.

What Is Stephen Hawking'S Theory Of Travelling To A Parallel Universe?
PROFESSOR Stephen Hawking, just two weeks before his death, presented a research paper in which he invited scientists to find another universe and predicted the end of the world. An eminent theoretical physicist and cosmologist co-authored a research paper on the existence of parallel universes like our own, published posthumously by the Journal of High-Energy Physics on Friday. The paper addresses a problem that has plagued Hawking ever since he developed the no-boundary theory with James Hartle in 1983.
In his final paper, Hawking, together with a professor of theoretical physics at the University of Leuven in Belgium, explored how to find these universes with spacecraft probes. The paper also predicts how our universe will eventually disappear into darkness when stars run out of energy.
Professor Hawking's suggestions have helped keep some of the most important parts of our hypotheses about the universe intact. If this theory is confirmed, it can be assumed that by that time other universes like ours could have appeared. Another theory of potential time travelers has to do with something called cosmic strings, narrow tubes of energy that run the length of the ever-expanding universe. It is hypothesized that these thin regions left over from early space contain vast amounts of mass and thus can warp space-time around them.
The new study builds on Hawking's earlier limitless theory, which predicted that if we go back in time to the beginning of the universe, the universe will shrink and close like a sphere. Hawkings had previously predicted a boundless theory that if you go back in time to the beginning of the universe, the universe would shrink and close like a sphere, but this new theory represents a step backwards from previous work. Starting from this boundary, the new theory predicts the final structure of the universes that emerged from the Big Bang.
But the theory also predicts a multiverse, meaning the phenomenon is accompanied by a series of other "big bangs" that create separate universes. Hawking helped develop the theory that led to the idea of infinite parallel universes. Modern physics has several theories about how the universe began, but one of the most popular is that the Big Bang was followed by repeated bursts of cosmic expansion, creating countless pocket universes scattered around the world. space.
