New explanation of the origin of dark matter

German scientists propose a new theory that explains the formation of dark matter after the universe was created.

Scientists at Johannes Gutenberg Mainz University (JGU), Germany, proposed a new theory of the formation of dark matter soon after. This model replaces the weakly interacting heavy particle model (WIMP), the best candidate for dark matter, which is the subject of various current studies, according to Science Daily. The results of the study are published in Physical Review Letters on August 7.

Invisible dark matter accounts for about 23% of the universe. Visible matter is made up of stars, planets and even life on Earth, which is only about 4%. The rest is. The current widely accepted hypothesis is that dark matter is a remnant of the universe, which has been stable since its later formation.

"We reconsidered this hypothesis and found that dark matter may have been unstable at the beginning of the universe," said Michael Baker, a member of the research team working in Energy Theory Physics Group. High (THEP) in JGU, said.

The stability of dark matter is often explained by the symmetry principle . But in the article, Michael Baker and his colleague Joachim Kopp prove that the universe experienced a period in which symmetry was broken. This means that dark matter particles are likely to decay. During the electroweak phase, symmetry stabilizes dark matter to re-establish, allowing it to continue to exist in the universe to this day.

So far, WIMPs (large interacting large particles) are considered the best candidates for the composition of dark matter. Scientists at the University of London (UCL), UK, have set up a Large Underground Xenon Detector (LUX) to detect traces of dark matter but have not been successful.

The research team said that the theory they proposed was related to the imbalance between matter and the universe. This can be confirmed in future experiments about.
