Have dark matter preceded the Big Bang?

The dark matter in the universe may have arisen before the Big Bang, which led to the universe being developed according to the most accepted theories, using a new mathematical framework developed for this purpose, a researcher at Johns Hopkins University has found.

According to Big Bang, or the Big Bang - the most widely accepted theory of the universe - the universe originated 13.78 billion years ago, after a big explosion followed by massive global inflation in a short time.

All forms of matter and energy, such as the known matter of atoms and dark (or dark) matter, emerged from this explosion.

Although dark matter is one of the biggest mysteries in the universe today and cannot be directly observed, scientists are aware that it exists because of its effect on visible matter.

They believe that they make up about 80% of the mass of the universe, and play an important role in the formation of galaxies and cluster groups, but the source and how they originated is still unclear.

All attempts by scientists to detect this material directly have failed, raising serious doubts about the theory that it is a residual material from the explosion.

If it were, the researchers would have been able to spot it directly during experiments with particle physics, opponents of the idea say.

According to the new scientific paper published by astronomer and physicist Tommy Tinkanen of Johns Hopkins University in the Physical Review Letters on August 7, using a new mathematical framework, the origins of dark matter may be more exotic than we know. Before the Big Bang.

Big Bang end of inflation and not its beginning !
The researcher believes that the events that occurred in the first moments of the age of the universe may need to be rearranged, the period of global inflation may have occurred before the Big Bang and not after.

In this case, the Big Bang is the name that should be given to the conditions that dominated the universe at the end of inflation.

If cosmic inflation occurred before the Big Bang, dark matter was found before the rest of things in the primordial soup of the universe, according to the mathematical modeling developed by the researchers.

According to the researcher, this new scenario of the emergence of dark matter in the universe can be empirically verified contrary to the current scenario, which seems flexible and unproven.

"If dark matter is made up of new molecules born before the Big Bang, it affects the way galaxies are distributed in the sky in a unique way," Tinkanen explains.

"This effect can therefore be used to reveal what this substance is and make conclusions about the period before the Big Bang as well."

This means that particles that have been massively produced during the brief time of global inflation can lead us to dark matter. So far, however, only one of these particles, the Higgs boson, has been discovered, which is not enough to give a clear idea of ​​dark matter.

"Although this type of dark matter is so elusive that it is hard to find in particle experiments, its existence can be detected by astronomical observation," he said.

Scientists expect the Oakland satellite, which will be launched by the European Space Agency in 2022 to study the period of global inflation, will help clarify much of the ambiguity about the nature of dark matter and how it originated.
