Black holes
It is well known that the Schwarzschild solution describes the gravitational field outside compact spherically symmetric mass distribution in General Relativity. In particular, it describes the gravitational field outside a point particle. Nevertheless, what is the exact solution of Einstein's equations with \delta-type source corresponding to a point particle is not known. In the...

Even if one would assume existence of Black Holes (BHs), High Energy Astrophysics observations cannot be explained because no free charge, no current can emerge from central singularities. In other words, even supposed charged BHs cannot have any electromagnetic property. In fact gravitational effects too should not propagate out of Event Horizons! Several authors try to resolve the BH...

Black holes
All alleged black hole solutions pertain to a universe that is spatially infinite, is eternal, contains only one mass, is not expanding, and is asymptotically flat. But the alleged big bang cosmology pertains to a universe that is spatially finite, is of finite age, contains radiation and many masses including multiple black holes (some of which are primordial), is expanding, and is not...

Questions:
• Is there a definitive observational/experimental proof of the existence of black holes?
• Are there theoretical problems with black holes?
• Are any understanding of mass gap between the supermassive black holes in centers of spiral galaxies and star-range black holes ascribed...
