Parallel worlds have attracted thousands of researchers; it has already been proven that this is a reality that exists in parallel. The physics of space can be both similar and different, there is witchcraft and magic, time flows differently. People who managed to accidentally find a portal to a parallel world, were absent for a long time, and only hours passed in another reflection.
Parallel worlds - what is it?
The idea that there are many worlds was put forward by the ancient philosophers Democritus, Metrodorus of Chios and Epicurus. Later, scientists developed the same theory, based on the principle of isonomy - equal being. The laws of physics argue that all dimensions are connected by photon tunnels, this allows you to move through them without distorting the law of energy conservation. There are versions about such portals:
- The door to another world opens in “black holes,” since these are funnels that suck in matter.
- It is possible to open a portal to a parallel world with correctly designed models of different mirrors. Such stone surfaces were found near the Tibetan pyramids, when expedition members began to see themselves in a different reality.
Parallel worlds - evidence of existence
For many years now, scientists have been debating: do parallel worlds exist? Serious studies of the problem were carried out in the middle of the last century, when scientist Hugh Everett published the materials of his scientific work, giving a formulation of photon mechanics through conditionality of states. The physicist was the first to notice the discrepancies between the wave and matrix formulas, which formed the basis of the theory of the Multiverse:
- During the selection process, all its possibilities are realized.
- Each choice is different from the others because it is implemented in a different reflection.
- It does not matter who makes the choice: an electron or a person.
The theory developed by physicists about the existence of many worlds is called the superstring theory or the theory of the Multiverse. Parapsychologists, for their part, argue that there are supposedly more than 40 portals to other dimensions in the world, 4 of which are located in Australia, another 7 in the USA, and 1 in Russia, in the Gelendzhik region, in an old mine. There is evidence that the young guy who decided to go down there disappeared for a week, and came up already very old, and did not remember anything about what happened.
How many parallel worlds are there?
Physicists suggest that the existence of parallel worlds is confirmed by superstring theory. It testifies that all the elements of the world are made of oscillating threads and membranes of energy. According to this theory, there can be from 10 to the 100th power to 10 to the 500th power of other dimensions. Mathematicians present their proofs. If parallel lines can coexist in two-dimensional space, and in three-dimensional space - parallel planes, then in four-dimensional space parallel three-dimensional spaces are also combined.
What does a parallel world look like?
Scientists find it difficult to describe parallel worlds, because the parallels cannot intersect, and it is difficult to visit that reflection for the sake of experience. In this matter we can only rely on the words of eyewitnesses. In their vision, parallel worlds are:
- nature of amazing beauty, inhabited by elves, gnomes and dragons;
- an area similar to a volcanic crater, bathed in crimson light;
- rooms and streets reminiscent of childhood places, filled with light.
The only thing in which the descriptions are similar is in the strong stream of light that appears from the void. Similar phenomena scientists saw in the pyramids of the pharaohs, the researchers came up with the version that the chambers are covered with unique alloys that glow in the dark. When trying to remove the chip sunlight, these alloys disintegrate, it is impossible to study them, so there is no exact data.
How to get to a parallel world?
Traveling to is one of the popular themes of science fiction writers and the dream of many inhabitants of the Earth. According to theorists, the simplest way is a dream, in which information is received and transmitted many times faster than in reality. If we talk about conscious movement, then the situation is somewhat different. According to esotericists, it is possible to get into another world, but it is very dangerous, since the different nature of the emitted waves can negatively affect the structure human brain. But through trial and error, several ways have been developed to help make such a journey:
- Lucid dream, which involves turning off consciousness and immersing yourself in another reality.
- Meditation. The techniques are similar.
- Using a mirror. Since ancient times, magicians have created special rituals for this.
- Via elevator. The transition is best done at night, alone, pressing the floor numbers in a certain sequence.
Creatures from parallel worlds
It’s difficult to say what parallel worlds are and what lives there. But a great many people have observed creatures from another reflection of reality at all times. It's not just about humanoids. The most known cases such meetings:
- '93 In Rome, people saw a glowing, golden ball that floated across the sky.
- 235 year. In China, the warring parties saw a large scarlet ball, which threw out rays in the form of daggers, moving from north to south.
- 848 The French noticed objects in the sky that were shaped like glowing cigars.
- fairies;
- poltergeists;
- Critters.
Movies about parallel worlds
There are many films about parallel worlds; directors and writers call this genre fantasy. There our world is depicted as part of the multiverse. All categories of viewers love to watch about parallel worlds. Most popular films:
- “Parallel Worlds” (2011, Canada)- adventure, fantasy.
- "The Chronicles of Narnia" (2005, USA)- pure fantasy.
- “Sliding” (1995 - 2000, USA)- a series closer to science fiction.
- “Fierce Planet” (2011, USA)- adventure, fantasy, thriller.
- "Verbo" (2011, Spain)- fantastic.
Books about parallel worlds
Are there parallel worlds on earth? – writers have been looking for an answer to this question for a long time. The very first tales about the Gardens of Eden, Inferno, Olympus and Valhalla completely fall under the category of stories about parallel worlds. The specific concept of the existence of other dimensions appeared already in the 19th century, with light hand H.G. Wells. IN modern literature There are hundreds of novels about time travel, but the following classics are called the pioneers:
- H.G. Wells, "The Door in the Wall."
- Herbert Dent, "Emperor of the If Country."
- Veniamin Girshgorn, "Unceremonious Romance".
- Jorge Borges, The Garden of Forking Paths.
- “Multi-tiered world” is a cycle of fantasy stories.
- “The Chronicles of Amber” is the most striking reflection of other dimensions in literature.
British scientists from Oxford have proven the existence of parallel worlds. The head of the scientific team, Hugh Everett, explained this phenomenon in detail, MIGnews writes on Friday.
Albert Einstein's theory of relativity was a consequence of the creation of the hypothesis of parallel worlds, which ideally explains the nature quantum mechanics. She explains the existence of parallel worlds even using the example of a broken mug. There are a huge variety of outcomes of this event: the mug will fall on a person’s foot and will not break as a result, the person will be able to catch the mug as it falls. The number of outcomes, as scientists previously stated, is unlimited. The theory had no basis in fact, so it was quickly forgotten. During mathematical experiment Everett, it was established that, being inside an atom, one cannot say that it really exists. To establish its dimensions, you need to take an “outside” position: measure two places at the same time. So scientists established the possibility of existence huge variety parallel worlds.
Parallel world: Will a person be able to live in another dimension?
The term “parallel world” has been familiar for a long time. People have been thinking about its existence since the beginning of life on Earth. Belief in other dimensions appeared with man and was passed down from generation to generation in the form of myths, legends and tales. But what are we modern people, do we know about parallel realities? Do they really exist? What is the opinion of scientists on this matter? And what awaits a person if he ends up in another dimension?
Opinion official science
Physicists have long been saying that everything on Earth exists in a certain space and time. Humanity lives in three-dimensional dimension. Everything in it can be measured in height, length and width, therefore within these frameworks the understanding of the universe in our consciousness is concentrated. But the official academic science acknowledges that there may be other planes that are hidden from our eyes. IN modern science There is a term "string theory". It is difficult to understand, but is based on the fact that in the Universe there is not one, but several spaces. They are invisible to people because they exist in a compressed form. There can be from 6 to 26 such measurements (according to scientists).
In 1931, the American Charles Fort introduced a new concept of “teleportation places”. It is through these areas of space that one can get to one of the parallel worlds. It is from there that poltergeists, ghosts, UFOs and other supernatural entities come to people. But since these “doors” open in both directions - into our world and one of parallel realities, – then it is possible that people can disappear into one of these dimensions.
New theories about parallel worlds
The official theory of a parallel world appeared in the 50s of the twentieth century. It was invented by mathematician and physicist Hugh Everett. This idea based on the laws of quantum mechanics and probability theory. The scientist said that the number of possible outcomes of any event is equal to the number of parallel worlds. There may be similar options infinite set. Everett's theory long years was criticized and discussed in circles of scientific luminaries. However, recently, professors from Oxford University were able to logically confirm the existence of realities parallel to our plane. Their discovery is based on the same quantum physics.
Researchers have proven that the atom is the basis of everything, like construction material any substance may occupy different position, that is, appearing in several places at the same time. Like elementary particles, everything can reside at several points in space, that is, in two or more worlds.
Real examples of people moving into a parallel plane
In the middle of the 19th century in Connecticut, two officials, Judge Wei and Colonel McArdle, were caught in the rain and a thunderstorm and decided to hide from them in a small wooden hut in the forest. When they entered there, the sounds of thunder ceased to be heard, and all around the travelers there was deafening silence and pitch darkness. They groped for a wrought-iron door in the darkness and looked into another room full of a faint greenish glow. The judge walked in and instantly disappeared, and McArdle slammed the heavy door, fell to the floor and lost consciousness. Later, the colonel was found in the middle of the road far from the location of the mysterious building. Then he came to his senses and told this story, but until the end of his days he was considered crazy.
In 1974 in Washington, one of the employees of the administrative building, Mr. Martin, went outside after work and saw his old car not where he left it in the morning, but on opposite side streets. He walked up to it, opened it and wanted to go home. But the key suddenly did not fit into the ignition. In a panic, the man returned to the building and wanted to call the police. But inside, everything was different: the walls were a different color, the telephone had disappeared from the lobby, and there was no office on his floor where Mr. Martin worked. Then the man ran outside and saw his car where he had parked it in the morning. Everything returned to its usual places, so the employee did not report the strange incident that happened to him to the police, and only spoke about it many years later. Probably on a short time The American found himself in parallel space.
In an ancient castle near Comcrieff in Scotland, two women disappeared one day, unknown to where. The owner of the building, named McDogli, said that strange things happen in it and there are old occult books. In search of something mysterious, two elderly ladies secretly climbed into a house that the owner had abandoned after an ancient portrait fell on him one night. The women entered the space in the wall that appeared after the painting fell and disappeared. Rescuers were unable to find them or any trace of the tartans. There is a possibility that they opened a portal to another world, entered it and did not return.
Will people be able to live in another dimension?
Eat different opinion about whether it is possible to live in one of the parallel worlds. Although there are many cases of people crossing into other dimensions, none of those who returned after a long stay in another reality completed their journey successfully. Some went crazy, others died, others unexpectedly grew old.
The fate of those who crossed through the portal and ended up in another dimension forever remained unknown. Psychics constantly say that they come into contact with creatures from other worlds. Supporters of ideas about anomalous phenomena they say that all the missing people are in those planes that exist parallel to ours. Maybe everything will become clearer if there is a person who can get into one of them and return back, or if the missing suddenly begin to appear in our world and describe exactly how they lived in a parallel dimension.
Thus, parallel worlds may be another reality that has remained virtually unexplored over all the millennia of human existence. Theories about them so far remain only guesses, ideas, conjectures, which modern scientists have only explained a little. It is likely that the universe has many worlds, but do people need to know about them and get into them, or is it enough for us to simply exist peacefully in our own space?
Is our universe really unique and unique? In endless spaces science fiction, and in Lately and a huge number of scientists have many theories suggesting the existence of universes parallel to ours.
What is parallel reality?
From parallel realities that may or may not interact with each other, to universes that form parallel to ours, the idea that there are more than one worlds is heard more and more often not only on the pages of novels and on TV screens, but and on scientific conferences and in peer-reviewed scientific publications.
The concept known in the world of science fiction as a "parallel universe" is one aspect of the astronomical theory of the multiverse. In fact, today there are a number of quite significant theories and evidence for the existence of the multiverse.
The emergence of the universe
Approximately thirteen and a half billion years ago, a very dense, infinitesimal singularity formed in the vastness of space. Then, according to the Big Bang theory, some change, the so-called trigger, caused this singularity to expand in all directions from the center.
The enormous energy released by this initial expansion raised the temperature of spacetime, but over time it cooled and began to allow photons of light to pass through.
In the end fine particles began to clump together and form large cosmic bodies, such as galaxies, stars and planets.
Evidence system
One of the questions that arises when considering this theory is: if the Big Bang happened to our universe, how high is the probability of the existence of another (or infinite number) parallel universe?
The modern technology at our disposal today limits our ability to observe space-time. Even if we were able to somehow observe the entire space of the Universe, its shape and density would not allow us to look beyond the boundaries of our Universe.
Although the idea of parallel universes and may seem outlandish to many, the laws of physics fully support its existence.
In addition, there are several theories about the origin and existence of the multiverse, and all of them are supported by a complex and proven system of evidence. In fact, some experts think that the existence of parallel universes is more likely than their absence.
Here are the most popular scientific theories, explaining the presence of the multiverse.
Parallel universes according to string theory
At the center of string theory is the concept of a “brane” - a kind of physical multidimensional fabric. According to string theory, parallel universes exist on separate branes, which are located outside the influence of each other.
This idea was first proposed by Paul Steinhardt from Princeton University and Neil Turok from the Canadian Institute Theoretical Physics in Ontario.
String theory assumes the multidimensionality of space. It is quite possible that in addition to our three-dimensional brane, there are other branes in multidimensional space that are also three-dimensional or consisting of four or five dimensions.
Our universe may exist in one sphere, which is located in one or more spheres.
Physicist Brian Greene speaks of the string theory multiverse as several separate three-dimensional “slabs” that independently exist in a multidimensional cosmos. According to string theory, there are ten dimensions of reality.
Daughter Universes
The theory of the multiverse, according to quantum physics, the branch that studies the smallest subatomic particles, assumes the regular occurrence of multiple parallel universes, in addition, sometimes even their interconnection is implied.
Quantum physics looks at the world in terms of probabilities, not results. The many-worlds interpretation of quantum mechanics relies on a concept called collapse wave function.
The description of a particle is contained in its wave function, as soon as scientists want to measure it individual characteristics, such as mass or velocity, the wave function collapses, and only a single measurable characteristic becomes known about the particle.
This gives rise to the possibility of a “split of worlds”: depending on the observers, the particle demonstrates different characteristics. For example, as soon as scientists decide to measure the parameters of a particle (say, speed) and lead to the collapse of the wave function, daughter realities break off from our universe in which observers will receive data about the position of the particle, its mass, its shape and other physical characteristics suitable for it.
It's like an interpretation of a Robert Frost poem. Imagine that you have come to an intersection where you can go right or left. Once you make a decision, existing universe gives rise to a daughter universe where you made a different decision. And in every universe, there is a copy of you who thinks that she is the only one.
Mathematical universes
Science community to this day enters into active debate about the nature of mathematics. What is mathematics? There are two answers:
- an extremely useful tool with which the laws of the universe are described;
- the separate fundamental reality that makes up the universe.
If we accept the mathematical nature of the universe, then it turns out that our observations of the universe are simply imperfect and are not capable of realizing its exact nature. The conclusion follows from this, suppose that our universe is an equation. Is this mathematical structure Is it the only possible one or can the equation be written in different ways? If it can be written in different ways, would all its possible variations represent parallel universes?
Infinite Universe
Scientists cannot say with certainty what the actual shape of space-time is, but it is most likely flat rather than spherical. If spacetime is flat and the universe is expanding, then it can expand indefinitely.
But if space-time is limitless, then at a certain moment it must begin to repeat itself, therefore there is a limited number of formations of matter particles.
Thus, if we observe the universe from a sufficient distance, it is likely that we could encounter identical copies of ourselves living other lives. This theory makes the universe look like an endless patchwork carpet with a repeating pattern.
Thus, many repeating parts exist next to each other in a giant motley mosaic of the universe.
Spacetime can expand indefinitely. If so, then everything in our universe must repeat itself at some point, creating repeating elements in an infinite pattern.
Universes within a universe
Parallel universes, according to the theory of chaotic inflation, can arise as isolated bubbles within a rapidly expanding universe.
The theory of chaotic inflation suggests that immediately after the Big Bang the universe expanded very quickly, and then began to slow down as it cooled.
Eternal inflation, proposed by Tufts University cosmologist Alexander Vilenkin, suggests that the process of rapid inflation created pockets in spacetime that cooled faster.
Thus our own universe, where rapid inflation has already ended, allowing stars and galaxies to form, is just a small bubble in a vast sea of spacetime, part of which is still rapidly expanding.
In addition, the scientist suggests that in some of these bubbles, the laws of physics and fundamental constants might differ from ours.
The belief in the existence of invisible neighbors borders on fantasy. Or with a sick imagination. That's what the skeptics say. And supporters stand their ground and give as many as 10 arguments in favor of an alternative reality.
1. Many-Worlds Interpretation
The question of the uniqueness of all things worried great minds long before the authors fantasy novels. The ancient Greek philosophers Democritus, Epicurus and Metrodorus of Chios thought about it. About alternate universes it is also said in sacred texts Hindus.
For official science, this idea was born only in 1957. American physicist Hugh Everett created the many worlds theory to fill the gaps in quantum mechanics. In particular, find out why light quanta behave either like particles or like waves.
According to Everett, each event leads to a split and copying of the Universe. In this case, the number of “clones” is always equal to the number of possible outcomes. And the sum of the central and new universes can be depicted in the form of a branched tree.
2. Artifacts unknown civilizations
Some finds baffle even the most experienced archaeologists.
For example, a hammer discovered in London, dated to 500 million BC, that is, a period when there was not even a hint of Homosapiens on Earth!
Or a computing mechanism that allows you to determine the trajectory of stars and planets. A bronze analogue of the computer was caught in 1901 near the Greek island of Antikythera. Research on the device began in 1959 and continues to this day. In the 2000s, it was possible to calculate the approximate age of the artifact - 1st century BC.
So far nothing indicates a fake. Three versions remain: the computer was invented by representatives of an unknown ancient civilization, lost by time travelers or... planted by people from other worlds.
3. Teleportation Victim
Misterious story Spaniard Lerin Garcia's life began on an ordinary July morning when she woke up in an alien reality. But I didn’t immediately understand what had happened. It was still 2008, Lerin was 41 years old, she was in the same city and house where she went to bed.
Only the pajamas and bedding changed color overnight, and the closet ran into another room. The office where Lerin worked for 20 years was not there. Soon the ex-fiancé, who had been dismissed six months ago, materialized “at home.” Even a private detective could not figure out where the current friend of his heart had gone...
Alcohol and drug tests were given negative result. As well as consultation with a psychiatrist. The doctor attributed the incident to stress. The diagnosis did not satisfy Lerin and prompted her to search for information about parallel worlds. She was never able to return to her native dimension.
4. Deja vu in reverse
The essence of déjà vu does not boil down to the familiar vague feeling of “repetition” and everyday foresight. This phenomenon has an antipode - jamevu. People who have experienced it suddenly stop recognizing familiar places, old friends and scenes from films they have watched. Regular jamevu indicates mental disorders. And isolated and rare memory failures also occur in healthy people.
A striking illustration is the experiment of English neuropsychologist Chris Moulin. 92 volunteers had to write the word “doors” 30 times in a minute. As a result, 68% of subjects seriously doubted the existence of the word. A glitch in thinking or instantaneous leaps from reality to reality?
5. The Roots of Dreams
Despite the abundance of research methods, the reason for the appearance of dreams still remains a mystery. According to the generally accepted view of sleep, the brain merely processes information accumulated in reality. And it translates it into pictures - the most convenient format for the sleeping mind. Solution number two - nervous system sends chaotic signals to the sleeping person. They are transformed into colorful visions.
According to Freud, in dreams we gain access to the subconscious. Freed from the censorship of consciousness, it hastens to tell us about repressed sexual desires. The fourth point of view was first expressed by Carl Jung. What you see in a dream is not a fantasy, but a specific continuation full life. Jung also saw a code in the dream images. But not from suppressed libido, but from the collective unconscious.
In the middle of the last century, psychologists started talking about the possibility of controlling sleep. Appropriate manuals have appeared. The most famous was the three-volume instruction manual by American psychophysiologist Stephen LaBerge.
6. Lost between two Europes
In 1952, a strange passenger appeared at Tokyo airport. Judging by the visas and customs stamps in his passport, he has flown to Japan many times over the past 5 years. But in the “Country” column there was a certain Taured. The owner of the document assured that his homeland was European state With thousand years of history. "The Alien" presented driver license and bank statements received in the same mysterious country.
Citizen Taured, no less surprised than the customs officers, was left overnight at a nearby hotel. The immigration officers who arrived the next morning did not find him. According to the receptionist, the guest did not even leave the room.
Tokyo police have found no trace of the missing Taured. Either he escaped through a window on the 15th floor, or he managed to transport himself back.
7. Paranormal activity
“Alive” furniture, noises of unknown origin, ghostly silhouettes hovering in the air in photographs... Meetings with the dead occur not only in the movies. For example, many mystical incidents in the London underground.
At Aldwych station, which closed in 1994, intrepid Brits hold parties, make films and periodically see a female figure walking along the tracks. On the metro station in the area British Museum hosted by the mummy of an ancient Egyptian princess. Since the 1950s, a dandy has been frequenting Covent Garden, dressed in the fashion of the late 19th century and literally melting before our eyes when anyone pays attention to him...
Materialists brush aside dubious facts, believing
contacts with spirits, hallucinations, mirages and outright lies of storytellers. Then why has humanity clung to ghost stories for centuries? Perhaps mythical kingdom of the dead– one of the alternative realities?
8. Fourth and fifth dimensions
The length, height and width visible to the eye have already been studied lengthwise and crosswise. The same cannot be said about the other two dimensions, which are absent in Euclidean (traditional) geometry.
The scientific community has not yet delved into the intricacies of the space-time continuum discovered by Lobachevsky and Einstein. But there has already been talk about a higher – fifth – dimension, accessible only to those with psychic talents. It is also open to those who expand consciousness through spiritual practices.
If we put aside the guesswork of science fiction writers, almost nothing is known about the non-obvious coordinates of the Universe. Presumably it was from there to ours three dimensional space supernatural beings are coming.
9. Rethinking the double-slit experiment
Howard Weissman is convinced that the duality of the nature of light is the result of the contact of parallel worlds. The Australian researcher's hypothesis connects Everett's many-worlds interpretation with the experience of Thomas Young.
Father wave theory Light in 1803 published a report on the famous double-slit experiment. Jung installed a projection screen in the laboratory, and in front of it was a dense screen-screen with two parallel slits. Then light was directed onto the cracks made.
Some of the radiation behaved like electromagnetic wave– stripes of light were reflected on the rear screen, passing straight through the slits. Another half luminous flux appeared as a cluster elementary particles and scattered across the screen.
"Each of the worlds is limited by laws classical physics. So, without their intersection quantum phenomena would be simply impossible,” explains Weissman.
10. Large Hadron Collider
The multiverse is not just theoretical model. French astrophysicist Aurélien Barrot came to this conclusion while observing the operation of the Large Hadron Collider. More precisely, the interaction of protons and ions placed in it. The collision of heavy particles produced results incompatible with conventional physics.
Barro, like Weissman, interpreted this contradiction as a consequence of the collision of parallel worlds.
Imagine a physicist sitting in a cage with a gun pointed directly at his head. Every few seconds, the spin direction of a random particle in the room is measured. If the spin is directed in one direction, then the gun fires and the physicist dies. If it’s the other way, then only the sound of a click is heard and the physicist survives. It turns out that the physicist's chances of survival are 50/50, right?
Everything may not be so simple if we live in a multiverse - that is, in addition to our universe, which we call home, there are many others.
The physicist and gun scenario begins a famous thought experiment called “quantum suicide,” and is one way to try to understand whether we live in just one of many (and potentially infinite) universes.
This thought experiment relies on quantum mechanics and the idea that objective reality does not exist. Everything we see around us is just one of the possible configurations of all the probabilities that this or that event will happen. One interpretation of quantum mechanics is that all other sets of probabilities can exist in their own separate universes. So if you follow the thought experiment with this interpretation in mind, when you measure the second particle, the universe will split into two, each with its own possible variant events: in which the physicist is alive and in which the physicist died.
His survival is now linked to quantum probability, so that he is both alive and dead at the same time - just in different universes. If new universe splits every time a particle is measured, and the gun either fires or doesn't, then in one of these universes the physicist will eventually survive, say, 50 particle measurements. You can compare this to throwing a coin 50 times in a row. The probability that you will get heads 50 times in a row is extremely small, but it is there - the chance tends to zero.
And if this happens, the physicist will understand that the multiverse is real, and in specific case- in the described experiment - the physicist is truly immortal, since the gun will never fire. But he will also the only person, who knows that these parallel universes exist. And how many physicists will have to be “expended” to find out for sure.
However, there are other, more reasonable versions of multiple universes that are supported by mathematics and are potentially testable.
“For some people, parallel universes are like jumping through a portal to another world or something,” says Matthew Johnson, a physicist at the Perimeter Institute. “But this is completely different.”
Actual observable evidence of multiple universes will be difficult to find, but not impossible. And here's how physicists plan to do it.
Multiverse versions
In fact, there are quite a few theories of the multiverse, and the multiverse from thought experiment with “quantum suicide”, where every possibility becomes reality, one of the most radical.
Massachusetts Physicist Institute of Technology Max Tegmark proposes splitting multiple universe theories into four different types to make it easier to think.
We will focus on the first level of multiverses - these versions are easier to understand than others. At the first level, we also have a pretty good chance of finding evidence that will prove that the multiverse is real.
Multiple universes follow from mathematical predictions already existing theories, and the first level multiverse is predicted by a very respected and powerful idea in physics: inflation.
What do we mean by "universe"?
To understand the idea of multiple universes, we first need to define what we mean when we say “universe.” Our definition of the “universe” has changed more than once, for example, when we invented the first telescope, looked into space and learned that the stars are not attached to the sky with nails, and the Earth is not alone in space.
But the universe is much larger than we can see with a telescope, Johnson says. Our universe represents only a sphere of light that has had enough time to reach us. If we wait another billion years, we'll see even more and our understanding of the universe will be upended again, Tegmark says.
Someone standing on a planet trillions of light years away would have a completely different picture of the "universe" based on how much light fell on their planet.
There is no way we can reach these other bubble universes by definition, because there is no way to move faster than light. Although we cannot see them, physicists believe that traces of their birth can still be detected.
Where is the proof?
The idea behind inflation is that during the birth of our Universe, there was a period rapid expansion(right after Big Bang) when a nanometer of space suddenly exploded across 250 million light years in less than one trillionth of a second.
Once inflation began, it never completely stopped. In some areas of space-time it stops, in which areas of space turn into bubbles like the universe that we see around us, but in other places space continues to expand. If the expansion is infinite, and many believe so, then new bubbles of universes are constantly being formed. This leaves a trail of bubbles. We drift through spacetime in the foamy Jacuzzi of universes.
Again, there is no way to communicate with these other bubble universes because we can't travel faster than light. But theoretically we can prove that they exist. And here's how.
When our bubble universe first formed, it is quite possible that it collided with other bubble universes that are forming around ours. It is unlikely that we are still close to them, since the ongoing expansion of space-time takes us further and further.
However, the impact of early impacts could have sent ripples through the cosmic microwave background (the heat left over from the Big Bang). Theoretically, we could notice these ripples using telescopes. She would be a discolored disk - like a bruise on the body of a microwave background.
Jones is looking for such “bruises,” but much depends on how quickly other bubble universes appeared and how many of them there may be. If there are few bubbles, we might not encounter them at all.
The Planck Space Telescope is currently listening to the skies for evidence of such collisions with other universes.
Various physicists hold different theories multiverse. This theory comes from string theory, as well as the idea that there are many other dimensions that we simply don't have access to (like McConaughey's character in Interstellar). Some physicists think that parallel universes lurk in these extra dimensions.
This multiverse idea is also testable.
Physicists will look for microscopic black holes at the Large Hadron Collider, which opened recently. It is impossible to produce a black hole at the LHC that would be dangerous, but, according to this theory, it is quite possible to create microscopic black holes that will instantly evaporate. The presence of black holes would mean that the gravity of our universe is leaking into extra dimensions.
“Because gravity can leak out of our Universe into extra dimensions, such a model can be tested by detecting miniature black holes at the LHC,” said physicist Mir Faisal. - We calculated the energy at which these black holes can be detected in a gravitational rainbow. If we find black holes at this energy, we will know that both the gravitational rainbow theory and the extra-dimensional theory are both correct."
However, there is no serious confirmation yet. Only doubts.
“I believe only what is supported by concrete, verifiable experimental evidence, and the concept of parallel universes certainly cannot boast of that,” says Brian Greene, a theoretical physicist at Columbia University.
The problem, Johnson says, is that physicists are moving away from philosophical discussions of multiple universes. Some just want to test an idea. Others hold radical and untestable theories. Tegmark says he will try a quantum suicide experiment when he is old and infirm. But let's hope he's just joking.
