Who discovers black holes?

Answer 1

Einstein's general theory of relativity (published in 1916) predicts black holes. Then a few months after Karl Schwarzschild gave a solution for the gravitational field of a point mass and a spherical mass, that a black hole could theoretically exist. Perhaps the first object to be generally recognized as a black hole is the X-ray binary star Cygnus X-1. Its effect on its companion star suggested as early as 1971 that it must be a compact object with a mass too high for it to be a neutron star. How the Black hole theory came from general relativity is that theoretically if a stars gravity is too strong it would implode/collapse into itself causing a black hole. Einstein determined that this is impossible.

Black Holes are purely theoretical and for them to exist goes against basic physics. Nobody has ever seen black hole. If a stars gravity was to strong it would explode and not form a black hole according to basic laws and physics.

Answer 2

Black holes have a long history; John Michel figured out some 200 years ago that something like "black holes" should exist, if it were possible to concentrate matter into a tiny space. The modern theory of black holes is somewhat different from Michel's arguments, though. Specifically, the modern theory of black holes is based on the General Theory of Relativity.

The actual discovery was more recent, and it took a while to recognize the X-rays observed, as black holes.

I suggst you read about "black holes" in Wikipedia, for example, to get a more thorough description of the theory - and also of the history.
