Dark matter and its intrusion are among the greatest mysteries of modern physics. But a new study from Johns Hopkins University says it may have formed before the Big Bang, he reports Scientific Alert.

Although dark matter makes up about 80% of the mass in the universe, we don't know much about it. for new study of Johns Hopkins University, however, could be made up of particles that appeared in a fraction of a second before the Big Bang. It also shows new ways to identify it through observation.

“The study revealed a new relationship between particle physics and astronomy. If dark matter consists of new particles forming before the Big Bang, they have a unique effect on how galaxies distribute. This relationship can be used to reveal their identity and knowledge of the times before the Big Bang, ”said Johns Hopkins University astronomer and physicist Tommi Tenkanen.

A key in the formation of the universe

Researchers have shown that dark matter plays a key role in the formation of galaxies and their clusters. Although it is not directly observable, it is known that dark matter exists because of its gravitational effects, which affect visible matter and form it in space, Science Daily. Using a mathematical structure, scientists have shown that dark matter could be formed before the Big Bang during a period known as cosmic inflation. With the rapid expansion of the universe, a number of particles have formed, called scalars, of which only the famous Higgs particle has been discovered to date.

The future of dark matter research is out the door

The study also suggested a way to track the origin of dark matter by observing its effects on visible matter in the universe. "Although this kind of dark matter is too euphoric to be discovered in particle experiments, it can be detected in astronomical observations," Tenkanen added. He also claims that we will learn more about dark matter and its origins in the coming years, which is attributed to the launch of the Euclidean satellite, which the European Space Agency wants to launch into space in 2022.
