Demystifying Nature Of Black Hole



Djurić Vladan

 

A black hole is a star with special properties. Firstly, it can "close", and secondly, it has incredible gravitational pull. There are several hypotheses about what is happening inside the black hole. According to theoretical data, gravitational forces draw in dying stars with a force proportional to its mass. The diameter of the black hole is only a few kilometres
According to recent studies, black holes cannot be aimed at destroying massive stars. In this case, infrared stars have a diameter of tens of thousands of kilometres, and neutron bodies - 15-30 km. Despite these figures, the mass of the black hole exceeds the mass of the largest stellar groups. According to researchers, in the very centre of a retracting star is a dense clot of a dying celestial body. In science, a black hole is also called the sphere of Schwarzschild - a German scientist who studied space. He is considered the first astronomer to discover a black hole.
The space of a black hole is distorted due to strong gravity, as a result of which photons and other elementary particles cannot escape from the hole. Thus, the space of a retracting star is separated from the galaxy. Stars die after overheating of the core. The temperature should reach more than 3.5 billion kelvin. Inside the star contains iron and other chemical elements. As a result of heating, the red-hot core starts a thermonuclear reaction without the possibility of its cancellation. In the red-hot nuclei of stars, particles and antiparticles are present. Scientists also noted a large number of gamma photons inside the nucleus. At the peak of evolution, a star can materialise or annihilate (annihilate).
It is noteworthy that elementary particles are able to pass through thick shells around the nucleus. After some time after overheating, the energy is transformed by the neutrino, freely leaving into outer space. Based on these data, scientists can suggest what is happening inside the black hole. However, the nature of the black hole is not fully understood. The fact is that under the influence of a strong gravitational force there are no elements inside. Therefore, when trying to photograph a black hole, researchers get only black spots. The more objects get into the hole, the more it gets
Multiple studies have been conducted for the Sun using simulation models. It is assumed that a black hole, cut off after overheating of the core of the Sun, would reach a radius of three kilometres. At the same time, a person could hardly have noticed that the Sun begins to squeeze due to the too large size of the star.
According to Sergei Popov, a Russian astrophysicist, it is generally not known what is happening inside the black hole. “No information from the inside out. We don’t have direct observational data. But if we use theories, for example, the general theory of relativity, the most important thing is that the body will move to a singularity. If the hole does not rotate, this is actually a point in the centre. If the hole it rotates, the singularity takes on a more cunning form. But the body falls irresistibly there, falls into the region of very large gravitational forces of high density and finally collapses.”
