Einstein's Equation

According to the principle of the general relativity theory, the gravity field equation should contain the field energy as a source of the field itself. Including the field energy-momentum tensor into the Einstein’s equation brings extra unknown quantities to the equation. Such equation is not suitable for a metric finding; however it allows – based on the known metric – calculating the whole energy-momentum tensor of both matter and gravitational field. As the gravity field metric, the metric of continuous field can be used, parameters of which are found from the generally covariant one-parametric equation. Here, the solutions are given of the equation for the spherically symmetric stationary problem. One of the solutions coincides practically with that by Schwarzschild for weak fields, while the other one describes an expulsive field
