Relativistic theory of gravitation

On the basis of the special relativity principle and geometrization principle and also considering the gravitational field as a physical field in the Faraday-Maxwell spirit possessing the energy-momentum and spin 2 and 0, the relativistic theory of gravitation (RTG) is constructed in an unique way. The source of gravitational field is the conserving energy-momentum tensor of matter and gravitational field in the Minkowsky space. The conservation laws of the energy-momentum and angular momentum of matter and gravitational field are strictly fulfilled in RTG. The theory explains the whole existing set of gravitational experiments. Due to the geometrization principle, the Riemannian space in this theory is of the field origin because as an effective force space it arises as a result. of the gravitotional field action on the matter. RTG produces a prediction of an exceptional strength: the Universe is not closed and it is only ''flat''. Whence if follows that there must be a ''hidden mass'' in the Universe is some form of matter
