Testing the Metric-Field Equations of Gravitation

Physical consequences from gravitation equations based on Poincar'{e} ideas of relativity of space and time in respect of measuring instruments are considered. The most interesting of them are the possibility of the existence of stable supermassive configurations $({10}^2÷{10}^{12}{M}_{\odot })$ which can exist in galactic centres, and an explanation of the acceleration of the Universe expansion as a manifestation of the gravitational force properties in the theory under consideration.
