Oppenheimer and his co-authors interpreted the singularity at the boundary of the Schwarzschild radius as indicating that this was the boundary of a bubble in which time stopped. This is a valid point of view for external observers, but not for infalling observers. Because of this property, the collapsed stars were called "frozen stars,"[13] because an outside observer would see the surface of the star frozen in time at the instant where its collapse takes it inside the Schwarzschild radius.

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.

HEY! WHY IS EVERYONE IGNORING STEPHEN HAWKING'S CONTRIBUTIONS. Because he's handicapped? That's a slap in the face and an insult to every handicapped scientist.
"...The black hole information paradox results from the combination of quantum mechanics and general relativity. It suggests that physical information could disappear in a black hole, allowing many physical states to evolve into the same state. This is a contentious subject since it violates a commonly assumed tenet of science—that in principle complete information about a physical system at one point in time should determine its state at any other time.[1] A postulate of quantum mechanics is that complete information about a system is encoded in its wave function, an abstract concept not present in classical physics. The evolution of the wave function is determined by a unitary operator, and unitarity implies that information is conserved in the quantum sense.
