In a new study, scientists have raised the possibility of an anti-universe that can go back in time and adapt to dark matter./p>
Some scientists believe that an "Anti-Universe" can exist in a place that resembles the mirror image of our own world and replicates almost everything we do. If this theory is correct, it could explain the existence of dark matter.
To understand such an idea, some preconditions are needed first. First, "Big Bang" or "Big Bang" which is a general term. This view includes a variety of theories that have been studied by cosmologists; Scientists trying to bring the cosmic clock as close to the beginning of the universe as possible.
Most scientists agree that matter has exploded, but there are differences, such as whether the temperature at that moment Was it initially very hot or was it absolutely zero?
there is also disagreement about what may have happened before the explosion. Could what we call Big Bang be the turning point of a larger leap forward? Imagine jumping on a trampoline and your feet almost touching the ground beneath it, then imagine that you only see the next upward jump; But without the first half, the jump is meaningless!
The next case is "Dark Matter," which, if it exists, may be even more confusing to scientists than the Big Bang. This is because this offense is definitely the key to helping complete the obscure puzzle. The question is what constitutes our world today, not the world billions of years ago. In fact, dark matter is a large part of matter in our universe, but humans have not yet been able to see it anywhere.

How does dark matter have a clear view of the universe but is hidden, and what are its properties? These are great secrets on which to base thousands of other ideas. there is now a very literal way to describe dark matter: "Dark" means that it is not light; in essence, it is a technical term for matter that does not reflect or emit any photons in a way that we can detect. But we can measure the physical (not visual) effects of dark matter on things like gravitational waves.
Now back to anti-universe theory. Could a newly discovered anti-world be parallel to our own world, but go back in time? If so, the world is essentially expanding "backwards" in the run-up to the Big Bang, just as our world is moving "forward" in time.
In a new article last month in Researchers at the Perimeter Institute for Theoretical Physics in Ontario, Canada, have suggested that the Big Bang may be smaller and more symmetrical than we think. They wrote: "Among other things, we will elaborate on the remarkable consequence of the hypothesis that there follows a very high-efficiency new explanation for dark matter."
An interesting thing about this model of the Big Bang. It eliminates the need for what scientists call "cosmic inflation." The period in which the universe expands widely to explain its magnitude immediately after its creation. Instead, it could have naturally expanded more slowly over time, making it easier for us to explain what happened.
And for these two worlds before and after to be truly symmetrical, particles must be Add to our existing understanding of the world around us. Today we know about neutrinos, very mysterious particles that are weak only in relation to gravity and interaction. If our universe is a reflection of a similar universe moving backwards at the time of the Big Bang, then what we call dark matter could actually be a version of a neutrino that is "right-handed," the opposite of the "left-handed" neutrino nature of the universe. We exist.
Although this may seem complicated and strange, the repetition and application of new theories is an important part of cosmology because scientists must have existing and published theories to make a decision by studying them. What is the next theoretical step? This is much easier to do by providing general answers and using observations and measurements, and so over time, as human understanding improves and more sophisticated ways of observing the universe develop, a beautiful sequence of ideas will follow.
