The astronomers discovered black holes that have their own electron. Black holes, like space objects, are notable for their simplicity. And it allows to draw parallels between them in different branches of physics. A group of researchers concluded that a special type of particles can exist around a binary system of black holes in the same way that an electron can be around a pair of hydrogen atoms.
And it is the first example of the existence of a so-called gravitational molecule. Investigating such object, the astronomers believe that they found a clue about the identity of dark matter and the basic nature of space-time.
And in order to understand the essence of that issue better, the scientists drew attention to one of the topics that is almost never discussed in modern physics, the field. It is a special mathematical tool that provides clues about the possibility of travel in the Universe. There is a kind of field called scalar. A scalar is a special mathematical way to mark just one number.
But other fields are vector, tensor, they are expressed in more than one number for each place in space-time. In the middle of the last century, the scientists began to pay special attention to the scalar field, and created the assumption that the Universe is in fact a field.
If we consider an ordinary electron, then quantum mechanics suggests that it is extremely difficult to determine where it is at a given time. When quantum mechanics was in its infancy, it was difficult for the scientists to understand. Modern physics presents the electron as a mathematical object, that is, as a field. It reacts to the environment and it is due to the reaction of the nearest atomic nucleus, which as a result is modified to change the place in which the electron can be seen.
As a result, it turns out that electrons can appear around the atomic nucleus, but not everywhere, but in certain places. A black hole in gravitational physics can be described using three data: mass, spin and charge of an electron. With coincidence of circumstances, you can use all the data at the same time to understand black holes better.
The electronic field of each atom reacts to the presence of the nucleus and allows the electron to appear only in certain areas. In a similar way, the scientists describe the state of the environment of a black hole. If we imagine a singularity at the center of a black hole, then the environment will be a scalar field, the very state where subatomic particle exists.
