Black holes are the result of believing that bodies move by gravitational geodesic. The first and second array element of the Schwarzschild metric are the mathematical inverse of each other. But if they were equal, then, even independently of the possible zeros and infinite, light cones never be closed. There would be no event horizons or black holes.

Connected theory, the only alternative to Einstein's general relativity, is the solution to the problems of theoretical physics today. See Bubok.com:
