Black Hole Singularities and Wormholes: Albert Einstein would have warned against them and Karl Schwarzschild would have corrected these ideas, caused by errors. This article explains extensively the history behind these errors and also how they must be repaired. It turns out that a so called Event horizon belongs in...

Einstein’s General Relativity contains the Laplace operator of a sphere of incompressible liquid. It links the time-like solution (how fast does the clock tick) directly with the gravitational potential: no need for using tensor operations. He never applied it to the potential inside a sphere. This article is doing...
