Who discovered the black hole? The whole process of black hole generation
Sihaiwang: Recently, the first black hole photo in human history was made public. Since then, black holes have been proved to exist in a real sense. Many friends think black holes were discovered by Einstein, others say Hawking, but they are not. Let's have a look.
Black hole discoverer: Carl & middot; Karl Schwarzschild, German physicist, astronomer and astronomer Martin & middot; Swasi's father.
Carl & middot; Schwarzschild was born in 1873 in Frankfurt, Germany. At the age of 16, he published a paper on planetary orbits. He studied at the universities of Strasbourg and Munich and received his doctorate in 1896. His research direction is Jules & middot; ONLEY & middot; Poincare's theory.
He has been an assistant at the kuffner Observatory in Vienna since 1897. There he developed a formula to calculate the properties of photographic materials, involving an index called the Schwarzschild index.
Black holes cannot be observed directly, but their existence and mass can be known indirectly, and their influence on other things can be observed. By releasing and gamma due to high heat before the object is inhaled; The 'edge information' of rays can obtain the information of the existence of black holes. It is inferred that the existence of black holes can also be obtained by indirectly observing the orbit of stars or interstellar clouds.
A black hole is a singularity with infinite density, infinite curvature of space-time, infinitely small volume and infinite heat in the center and a part of the empty sky around it. It is invisible within the scope of this sky. According to Albert Einstein's theory of relativity, when a dying star collapses, it will gather and become a black hole, swallowing all light and any matter in the adjacent universe.
The generation process of a black hole is similar to that of a neutron star: a star is preparing to perish, and the core shrinks, collapses and explodes rapidly under the action of its own gravity. When all the matter in the core becomes neutrons, the contraction process stops immediately and is compressed into a dense star. At the same time, it also compresses the internal space and time.
But in the case of a black hole, because the mass of the stellar core is so large that the contraction process goes on endlessly, even the repulsive force between neutrons can not be stopped. The neutron itself is crushed into powder under the attraction of squeezing gravity itself, and the rest is a matter with unimaginable density. Due to the gravity generated by high mass, any object close to it will be absorbed by it.
