Could dark matter be older than the Big Bang?

it is believed that before the Big Bang there was nothing.
Dark matter eludes for quite some time. Its existence is first mentioned in the 1920s, the Dutch astronomer named Jacobus Kaptein. Well-known radio astronomer, Jan Oort was later strengthened the hypothesis of the existence of dark matter in the early 1930-ies, when he discovered that there must be more mass than is observed to force the Local group of galaxies move as it happens. And in August 2006, NASA found a direct proof of the existence of the greatest mysteries in the Universe — . According to a recent study, dark matter existed before the Big Bang. But how is this possible?
how do we know dark matter exists?
not be observed directly, but its existence is due to the strange gravitational effects that it has on matter and space allocation. It is assumed that dark matter is about 80% of the total amount of matter in our Universe. At the same time, we know almost nothing about her. The mystery becomes even more incomprehensible when it joins dark matter dark energy. Our is made up of 27% dark matter, 68% dark energy and only 5% — it is a common matter. And Yes, all of our knowledge about the Universe based on these 5%.
Today, researchers from the Johns Hopkins University trying to figure out the origin of dark matter. In his recently published study, they shared a new idea about how dark matter was born. According to one of the study's authors Tommy Tenkanen the work of scientists has identified a new link between the physics of elementary particles and astronomy.
the universe is constantly expanding after the Big Bang.
Perhaps dark matter consists of particles that existed before the big Bang. These particles explain the extraordinary distribution of galaxies throughout the cosmos right now. In addition, Tenkanen explained that this newly discovered compound can be used to investigate the conditions that preceded the Big Bang. Until now, researchers believed that — it is a remnant of the Big Bang. However, the experimental searches so far have been unable to find these particles.
When did dark matter?
To date, was discovered only one of the potentially existing particles — . The researchers argue that we still don't know what dark matter is, but if it has any relation to the so-called scalar particles — elementary particles, which were formed in the process of inflation, dark matter can be older than the Big Bang itself.
May not have given rise to dark matter
The Formation of dark matter before the Big Bang in itself is not a new idea. However, this idea never supported by mathematical calculations, so this study is currently the only of its kind. Tenkanen commented that scholars overlooked a simple mathematical scenario for the origin of dark matter. A study published in .
