What happened after Big Bang: Supermassive Black Hole and Dark Matter are also included in many unsolved mysteries of the universe. A team of astronomers has proposed that both mysteries can be explained by primordial black holes in a model going away from the traditional model that describes the universe. The study also states that black holes have existed since the universe’s beginning. Researchers say that no separate new particles or new physics will be needed to prove all this.
Dark matter and supermassive black holes
This new study has been accepted for publication in The Astrophysical Journal. Where the existence of dark matter has not yet been practically proved, it is used to prove many astronomical phenomena. On the other hand, supermassive black holes are the supermassive black holes located at the center of all galaxies, including our Milky Way. But when they started to be made is still a profound mystery.
The time of the big bang
These included Nico Capalutti of the University of Miami, Günter Hasinger, Science Director of the European Space Agency, and Priyamvada Natarajan of Yale University, have suggested that black holes had existed since the beginning of the universe, that is, shortly after the Big Bang. Along with this, these researchers also say that these primordial black holes themselves can be dark matter.
Supermassive to tiny black holes
Hassinger said that black holes of different sizes are still a mystery. We do not understand how such massive supermassive black holes have evolved in such a short time since the existence of the universe”. On the other hand, observations from the European Space Agency Gaia indicate that there may be tiny black holes. If they exist, they are too small to be formed from dying stars.
Merger from the beginning?
Nico Capalutti said, “Our study shows that these mysteries of modern astronomy can be solved without the concept of new particles or new physics. This includes the nature of dark matter to supermassive black holes. If most black holes were formed shortly after the Big Bang, they would have started to merge, making them more massive black spots over time.
Information about initial mergers can be found
If primordial black holes exist, then the European Space Agency’s future gravitational wave space observatory, LISA (LISA), might catch signs of their merger. Tiny black holes may have remained only primordial black holes that have not yet been found in larger black holes.
A universe full of black holes
According to this model, the entire universe must have been filled with black holes. Stars may have started to form around clusters of dark matter that would have created the Solar System and Galaxy over billions of years. If the first stars were indeed to form around primordial black holes, their presence in the universe would have been much earlier than expected by the Standard Model.
Priyamvada Natarajan says that if primordial black holes exist, then they must have been the seed of all black holes, one of which is present in the center of our galaxy Milky Way. The European Space Agency’s Euclid mission will study the dark universe more than ever before. It may play a role in searching for dark matter bodies and identifying primordial black holes.
The James Webb Space Telescope of NASA, the European Space Agency, and the Canada Space Agency will be a kind of astronomical time machine that will give information about the universe of the last 13 billion years ago and shed more light on this mystery. Gunter says that if early stars and galaxies were already formed from the so-called Dark Ages, the Webb telescope could find evidence of these.
