Dark matter shock: Scientists speculate that mystery substance exists before the big bang Science | news

Dark matter is likely to make up an incredible 80 percent of the universe's mass. But the only fact is the extent of our knowledge of this mysterious, all-pervasive substance, with scientists not knowing exactly what it is and how it came about. Now, a groundbreaking study has revealed that dark matter may be even more bizarre than previously thought, as its origin may be prior to the beginning of the universe – the Big Bang.

Dark matter is difficult to detect because it is not directly observable.

Scientists know that dark matter more than fivefold dominates ordinary matter in the universe.

This is because galaxies spin too fast to cling to their stars.

Without this dark matter, laws hold them together According to physics, these galaxies would fall apart.

For example, the Milky Way rotates so fast that it has to contain 30 times more dark matter than ordinary matter.


Tommi Tenkanen, a post-doctoral researcher in physics and astronomy at Johns Hopkins University and author of the study, believes a new link between particle physics and astronomy has been found to have.

He said, "If the ark matter is made up of new particles that were born before the Big Bang and that affect the distribution of galaxies in the sky in a unique way.

"This connection can be used to reveal their identity and draw conclusions about the pre-Big Bang era as well.

The shock findings contradict a long-held assumption that dark matter is a remnant of the Big Bang in 201


Tenkanen added, "If dark matter really were a remnant of the Big Bang, researchers would have in many cases have already had to see a direct signal of dark matter in different particle physics experiments. "

The seismic study shows how dark matter could have been produced before the Big Bang, the dominant cosmological model for the observable universe, and at unimaginable speeds.

This expansion is intended to lead to the introduction of bizarre particles such as the famous Higgs boson

Mr. Tenkanen added, "We do not know what dark matter is, but if they do anything with scalar particles it may be older than the Big Bang.

"In the proposed mathematical scenario, we do not need to assume new types of interactions between visible and dark matter beyond gravity that we already know exist. "

The astrophysicist believes that the potentially groundbreaking results have been overlooked so far because scientists have overlooked the simplest possible mathematical scenario for the origin of dark matter.

And the research could even lead to a new way to test the theory by observing the dark matter signatures about the distribution of matter in the universe.
