How to make a black hole without a star
Currently there are two widely known varieties of black holes: black holes of stellar mass, which are smaller and are formed when a large celestial body “falls into itself” through a supernova explosion; and supermassive black holes, which are formed as a result of mysterious circumstances. The last type of black holes is still a mystery to scientists, but recent research in this area sheds light on the mystery.

According to theoretical physicists, the entire early universe was permeated supermassive black holes can accumulate dust and gas, which later turned into the galaxy in the form in which they exist today. Main question: how might have the first black holes, if there were no stars, they could be born?

In fact, the mystery is an answer to the paradoxical question of “the chicken and the egg”. A new study published in the Astrophysical Journal Letters, demonstrates a model of how these objects could be formed without stars, to which previously there was no real scientific explanation.
Shantanu Basu, Professor of physics and astronomy at Western canadian University in Ontario, explains that the model is based on the alternative idea that leads to the cessation of growth of black holes.

On the one hand, there is a model of the “collapsar”. In this case, the “gravitational collapse stops intense heat and radiation pressure, which is generated in the center collapsible gas fragment, also known as star.” On the other hand, there is the so-called “direct collapse”. It is based on the assumption that supermassive black holes can be formed very quickly within a very short period of time and then almost immediately stop.
Immediately after the Big Bang, the young Universe was very much rarefied gas and dust just scattered all over the space-time. Some of them accumulate in such huge balls that they are quanta collapse into the dark ultraplate of the body, which are in place to form black holes. They start to “eat” fresh gas and dust the young Universe without any fuse is pressure – injected substance is virtually endless. In the end, the radiation created by all these black holes and other newborn stars in the Universe, stops their mass distribution and growth, leaving what we now call supermassive black holes.

In other words, during the first 800 million years after the Big Bang, black holes originated and grew very very fast and then suddenly stopped growing.
The new article actually does not explore the formation of black holes directly. It puts forward a model that explains how the map of supermassive black holes in the Universe looks. This distribution works best with the model of direct collapse of the early formation of the black hole.

Of course, the “direct collapse” – this is only theory. Shantanu Basu hoped that future research can move forward with these results, to learn more about the history of the growth of these incredibly massive objects and also to confirm or refute the idea of the direct collapse. The fact that scientists were finally able to display them, means that humanity has become a step closer to a solution.
We will remind that earlier scientists gave an exhaustive answer to the question of why the space is cold and the Sun hot. And recently, astronomers have recorded the “cosmic birth” in the Universe.
