  The problem posed by Einstein in 1913 related to the inclusion of the
energy-momentum tensor of the gravitational field in the equation of the same
gravitational field has been solved. At the same time, it was possible to
preserve the covariance of the equation. In small fields, the new gravitational
field equation successfully transforms into the Einstein equation. The new
equation implies a local conservation law. The numerical solution of the
equation is given. The numerical solution for g_{00} is given. This parameter
is strictly positive. Within the region of large fields the value quickly drops
to almost zero. The region where extremely small values of g_{00} can be found
corresponds to the interval 0 < r < 3.4 r_g. This interval is close to the
observed radius of neutron stars. It follows that neutron stars and "black
holes" are of the same nature. There are no singularities in the solutions of
the equation.
