Parallel universes exist, physicists collect evidence

Have you ever caught yourself thinking that you exist in a parallel Universe and everything is different there? However, such reflections, when scientists, and not ordinary people indulge in them, can tell a lot about how our Universe works.

So, one of the last scientific works of theoretical physicist Stephen Hawking was devoted to parallel universes and the ways by which one can prove / disprove their existence. But even if parallel universes exist, what are they?

What do physicists think of parallel universes?

According to Themindunlished.com, theoretical physicist Sean Carroll expressed the opinion that the small-scale structure of the Universe indicates the existence of many parallel worlds. Shocking comments were made on the Jeff Rogan Experience (JRE) podcast last year. Carroll says that the fact that tiny particles such as electrons and photons do not have one given location in the universe suggests that there are many parallel universes.

It should be noted that quantum physics is something that the human imagination does very poorly at. For this reason, many pseudoscientists and all kinds of gurus are very fond of entangling a couple of words about quantum physics in their own ideas about the Universe. They proudly declare this at seminars and write posts on social networks. As they say, if you do not understand what is happening, start talking about quantum physics. So you need to be very careful and be able to distinguish speculative statements from statements by real scientists.

In a recently published article on the mysteries of light, we discussed quantum physics - the dance of electrons around the nucleus of atoms. This once again confirms what we already knew - at the quantum level, everything is really different. Just think about it - the empty vacuum of space is filled with tiny particles that constantly appear and disappear. That being said, Bell's Theorem - a fundamental construction in quantum mechanics - can prove the existence of multiverse. This theorem deals with situations where particles interact with each other, get entangled, and then diverge in different directions. Of course, there are also equations, laws of physics, and patterns that must be obeyed, but Carroll does not exclude that some alternative worlds may actually exist.

In the past, Carroll has put forward several innovative but conflicting theories about the nature of time and the Big Bang. According to one of his hypotheses, the Universe did not arise as a result of a giant explosion, but is an infinitely ancient, constantly expanding Universe, in which time can flow both forward and backward. Sounds exciting, doesn't it? Carroll also believes that quantum physics is not just an approximation to the truth. Now scientists are faced with the secrets of dark matter and dark energy, and given the fact that not everything agrees with Einstein's General Theory of Relativity, it's time to start our understanding of the quantum world.

In 2011, physicist Brian Greene wrote a book called Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos. In it, the British physicist and popularizer of science writes that scientists cannot avoid having any version of the multiverse in their research. Many physicists are thinking about one or another version of the theory of a parallel universe. If all this is complete nonsense, then it is a waste of time and energy. But if this idea is correct, then this is a truly fantastic revolution in our understanding of the world and the Universe.

Stephen Hawking also suggested that, thanks to quantum mechanics, the Big Bang gave us an infinite number of universes, not just one. To try to prove the presence or absence of parallel worlds, Hawking, in collaboration with Thomas Hertog of the University of Leuven (Belgium), suggested that if the multiverse existed, it should have left a trace in the relic radiation. It can be detected by a probe with a special detector, which Hawking and Hertog propose to send into space. Read more about this amazing mission in our dedicated article.

So it is possible that Green, Carroll, Hawking and Hertog are right. Researchers at Oak Ridge National Laboratory in Tennessee recently announced their desire to find out if multiverse or mirror images of our own reality exist. New Scientist writes about this, so we are waiting for further details and hope that they will succeed soon!
