It is called a black hole because it is like an ideal bold body because it has no light. According to the theory of general relativity, a black hole has no locally detectable features, but it affects the fate and circumstances of the objects that cross it.

Black holes have once again attracted the attention of astronomers after NASA’s recent interest in research. A black hole is neither black nor a hole. It’s far from that. In short, a black hole is a huge, compact astronomical object so dense that its gravity prevents anything from escaping, even light. The concept of black holes originated from the general theory of relativity by Nobel Prize winner Albert Einstein, which predicts that a sufficiently compact mass will form a black hole.
Black hole: neither black nor hole
It is called a black hole because it is like an ideal black body because it has no light. According to the theory of general relativity, a black hole has no locally detectable features, but it affects the fate and circumstances of the objects that cross it.
When a large number of stars collapse at the end of their life cycle, a black hole is formed. After formation, it grows by absorbing the mass of the surrounding environment. By absorbing other stars and merging with other black holes, it can become a supermass black hole with millions of solar energy. It can also be created through the collapse of the Qi Cloud. Obviously, super-large black holes exist at the centers of most galaxies.
Who discovered the black hole?
The first astronomer, the pioneer of the British astronomer and clergy, was the first astronomer to think that a human body could be large, and even the light could not escape. French scientist Pierre-Simon Laplace also independently proposed the idea. Michel wrote in 1784 that a star with the same density but 500 times the radius of the sun will not allow any emitted light to escape because its surface escape speed will exceed the speed of light. He also said that such a huge non-radiative corpse could be detected only by the gravity effect on the visible corpses nearby.
Albert Einstein: Relativity
Albert Einstein developed his general theory of relativity after he showed in 1915 that gravity did affect the movement of light. Karl Schwarzschild found a solution to Einstein’s magnetic field equation, which describes the gravity field of point mass and spherical mass. It is now also confirmed that the simplest static black holes have mass, but neither charge nor angular momentum. These black holes are called Schwarzschild black holes.
