Dark matter is older than the Big Bang and is outside the universe The groundbreaking research of scientists from Johns Hopkins University spread like wildfire around the world of astronomy and aroused 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 done research that has shown us something that happened before everything was created. It's hard to comprehend, because with the Big Bang there was time and space, so how could anything have been before ?!

Astronomers at Johns Hopkins University described in the journal Physical Review Letters that before the Big Bang there may have been dark matter, which today makes up 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 through astronomical observations.

Dark matter plays a key role in the formation of galaxies and galaxy clusters, so understanding its essence is essential in understanding their formation and the development of the entire universe. Although we cannot observe it directly, we know that it is interacting gravitatively with Baryonic matter.

“The study revealed a new link between particle physics and astronomy. If dark matter is made up of new particles that were born before the Big Bang, they affect the way galaxies are arranged in the sky in unique ways. This combination can be used to reveal their identity and draw conclusions about the pre-Big Bang era, ”said Tommi Tenkanen, associate professor of physics and astronomy at Johns Hopkins University and author of the study.

Many astronomers believe that dark matter may be a leftover from the Big Bang, but so far experiments have failed to confirm this theory. So scientists decided to check whether it could have existed even before the Big Bang.

They used a new, simple mathematical structure in their study. The study showed that dark matter may have formed before the Big Bang in an era known as cosmic chaotic inflation, when space was expanding rapidly. Rapid development is believed to lead to the abundant production of certain types of particles called scalars. So far, only one scalar molecule has been discovered, the famous Higgs boson. The new study also suggests a way to test the origin of dark matter by observing signs of dark matter on the distribution of matter in the universe.

“We don't know what dark matter is, but if it has anything 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 interactions between visible and dark matter beyond the gravity that we know is there, 'explains Tenkanen.

Many scientists suggest that our universe is not the only one. It is quite possible that dark matter fills the space outside of our universe where it is located. It is there that other Universes are to exist and form, similar to the principle on which planets were formed in the Solar System.
