Black holes: these are the mysteries that surround them – El Tiempo

NASA defines a fried hole as an out-of-orbit object with such a strong gravitational pull that no one, not even light, can escape it. The “surface” of a fried hole, called the event horizon, defines the limit where the speed required to avoid it exceeds the speed of light, which is the speed limit in the cosmos. Matter and radiation are locked up and cannot get out.

If we know it well enough, science currently doesn’t know what’s inside a fried hole, and studying it is a constant source of fascination that has yielded eye-opening results, like the latest image which we saw from the fried hole in the center of the Milky Way. the week. However, there are still many mysteries surrounding them and the theories surrounding them.

Black holes: the beginning and the end of the universe

Dark matter, the mysterious substance that bounces around but doesn’t interact with light, could be tiny black holes penetrating the universe. And according to a new theory, these black holes could be made up of Fermi spheres, or quantum “pockets” of subatomic particles called fermions that flattened into dense pockets during the universe’s infancy.

According to Live Science magazine, the theory could explain why dark matter dominated the universe.

“We found that in some cases the Fermi spheres are so dense that the fermions are too close to each other, causing a Fermi sphere to collapse into a fried hole,” said Ke-Pan Xie, researcher at the Center for Theoretical Studies. Physics at the Francoist University of Seoul in South Korea.

Xie and his collaborator Kiyoharu Kawana, still at the Center for Theoretical Physics, imagined a new circle to explain how dark matter came to dominate the universe: In the midst of an incredible transformation, when the cosmos had less a second of age, a A new type of particle was captured and collapsed into such a small point that they became black holes. These black holes then flooded the universe and provided the weight needed to explain dark matter.

Astronomers and physicists cannot explain dark matter, a substance that makes up more than 80% of the mass of all major structures, from galaxies to the universe. This theory proposes the possibility that dark matter comes from black holes.

Finally, like dark matter, black holes do not emit light. “As a kind of non-luminous compact object, black holes are a natural explanation for dark matter,” Xie told the science publication.

Despite this, astronomers have long known that normal sidereal-mass black holes cannot explain dark matter in the Universe. This is because not enough stars have formed in the history of the universe to create enough black holes to account for known dark matter.

But the first moments of the universe were marked by amazing physics. What happened back then can happen by creating billions of little black holes. These black holes could persist to the present day and potentially solve dark matter masking.

They are believed to be black holes formed shortly after the Big Bang, when high densities and other cosmological conditions caused sufficiently dense regions of the early universe to collapse. Primordial black holes created not by the gravitational collapse of one but by the extreme density that the universe had at the start of its expansion.

The new study (published in June on the preprint data mat arXiv and whose article has not yet been peer-reviewed) could further promote another theory proposed by Roger Penrose in 2010, known as conformal cyclic cosmology. (CCC).

According to this theory, much of the matter in the universe will eventually be pulled around supermassive black holes, which have masses on the order of millions to tens of billions of solar masses.

If both theories were true, it would mean that the beginning and end of the universe revolved around black holes.
