Instead of being a confirmation of Einstein's general relativity, what astronomers are claiming to observe are direct refutations of the theory. Beginning in the sixties, primarily mathematicians started rewriting general relativity to make it more palatable to the general public.

Black holes are said to "swallow" everything that passes through their even horizon. General relativity describes geodesic motion, and all motion stops at the event horizon.

According to Hawking's rather superficial analogy with field theory, black holes are said to radiate with a thermal spectrum. All observed black holes are seen to radiate with a definite non-thermal spectrum.

Nothing can escape from a black hole, neither light nor gravity. Then how can you explain LIGO's claim that it has observed gravitation waves from the merge of a pair of binary, orbiting black holes. Where is the gravitational attraction that would put them in a binary orbit?

General relativity is incapable of solving the two-body problem. Yet, its numerical counterpart says that it has successfully modeled the merger of two black holes using the 3+1 decomposition of spacetime. Yet, there is no unique time-slicing in general relativity, and no preference of the choice of coordinate systems.

Wobbling jets emitted by black holes immersed in the accretion discs are shown in the figure.

Missing from the artist's design is the event horizon, and the blackness of the black hole. Rather, as Kundt has repeatedly claimed, what is been seen are neutron stars inside accretion discs, or is the central engine of an AGN (active galactic nuclei), a nuclear burning disc. In any event, it has absolutely nothing whatsoever to do with a black hole--at least as general relativity defines it.

The famous solutions of the Schwarzschild metrics consist of an outer, non-constant, and inner, constant, curvature solutions to Einstein's equations in the vacuum, although the outer solution professes to have a mass concentrated at the origin. This arises when an arbitrary constant of integration has been identified as the mass on the basis that the asymptotic weak gravity limit must correspond to Newtonian gravity.

Neither solution can be prolonged beyond their natural boundaries. The boundary of the outer solution is precisely, the event horizon defining the Schwarzschild radius. The inner solution, on the other hand, is analogous to the Poincare' disc model of the hyperbolic plane. Since Einstein was not well-versed in non-Euclidean geometries, the apparent singularity at the origin of the outer solution troubled him deeply, and he, with his assistant Rosen, sought to build bridges over them.

This was completely unnecessary since they were not part of the model. Consequently, black holes have no appetite for anything, and all the folklore that has grown up around them, like the so-called the information paradox, are nonsensical consequences of that folklore together with their "fire-wall" solutions.
