On one fundamental property of gravitational field in the field theory

It is shown that the universal property of gravitational field to slow down the rate of time leads in the field theory to a fundamental property — generation of effective forces of repulsion. There is a common belief that the gravitational field provides only forces of attraction. It is seen, for example, from the fact that the physical velocity of a test body increases when it is approaching the gravitating body. However this is not quite so for strong fields. Let us consider this later. When A. Einstein had connected gravitational field with the Riemannian space metric tensor in 1912 it was found that such a field was slowing down the rate of time for a physical process. This slowing down can be demonstrated, in particular, by the example of Schwarzschild solution, if we compare the rate of time in the gravitational field with the rate of time for a distant observer. Nevertheless in general case there is only Riemannian space metric tensor in General Relativity and there are not any indication of the inertial time of Minkowski space. Just for this reason the universal property of gravitational field to slow down the time rate in comparison to the inertial time could not be further developed in General Relativity. The situation is rather opposite in the Relativistic Theory of Gravitation (RTG) as it is a field theory. In this approach the gravitational field is treated as a physical field of Faraday-Maxwell type which is developing in Minkowski space in line with all the other physical fields. The source of universal gravitational field is the total conserved energy-momentum tensor of all matter including the gravitational field. Therefore the gravitational field is a tensor field with spins 2 and 0. Just this fact leads to geometrization: the effective Riemannian space arises but with trivial topology.
