The latest sensational study by scientists at Johns Hopkins University flared around the world of astronomy and sparked a lot of controversy. They tell us that the Big Bang was not the beginning.
Until now, astronomers have focused on everything that happened in our universe after the Big Bang. Meanwhile, scientists from the United States have conducted research that showed us something that took place before the creation of everything. It’s hard to understand, because with the Big Bang time and space were created, so how could something have been before ?!
Astronomers from Johns Hopkins University described in the journal Physical Review Letters that before the Big Bang there could have been dark matter, which today accounts for about 30 percent of our universe’s space. Researchers not only explain how dark matter could have formed, but also how it can be identified during astronomical observations.
Dark matter plays a key role in the formation of galaxies and galaxy clusters, which is why the concept of its essence is necessary in the process of understanding their formation and development of the entire Universe. Although we cannot observe it directly, we know that it is interacting with gravity with baryon matter.
“The study has revealed a new relationship between particle physics and astronomy. If dark matter consists of new particles that were born before the Big Bang, they affect the way galaxies are arranged in the sky in a unique way. This combination can be used to reveal their identity and draw conclusions about times before the Big Bang, “said Tommi Tenkanen, postdoctoral degree in physics and astronomy at Johns Hopkins University and author of the study.
Many astronomers believe that dark matter may be a remnant of the Big Bang, but so far it has not been possible through various experiments to confirm this theory. So the researchers decided to check whether it could exist before the Big Bang.
In their study, they used a new, simple mathematical structure. The study showed that dark matter could have arisen before the Big Bang in an era known as cosmic chaotic inflation, when space exploded rapidly. Rapid growth is thought to lead to abundant production of some types of particles called scalars. So far, only one scalar particle has been discovered, the famous Higgs boson. The new study also suggests a way to test the origin of dark matter by observing the signs of dark matter on the distribution of matter in the universe.
“We don’t know what dark matter is, but if it has something to do 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 interaction between visible and dark matter beyond gravity, which we know is there, “explains Tenkanen.
Many scientists suggest that our universe is not the only one. It is quite possible that black matter fills the space outside our universe in which it is located. It is in it that other universes are to exist and form, in a similar way as planets were formed in the solar system.
