Demonstration that the 2 fundamental equations of Einstein's general relativity, geodesics and gravitational equations of Einstein's gravitational field, are incompatible with the phenomenon of gravitational redshift, according to which the time stationary, measured by a clock lighting, takes more slowly the greater the gravitational potential. Consequently, it is postulated the fundamental equation of the theory connected. This intertwined with subparagraphs that solve the problem of event horizons and Schwarzschild black holes.
