Gravity theory is the basis of modern cosmological models. Thirring-Feynman'stensor field approach to gravitation is an alternative to General Relativity(GR). Though Field Gravity (FG) approach is still developing subject, it opensnew understanding of gravitational interaction, stimulates novel experiments onthe nature of gravity and gives possibility to construct new cosmologicalmodels in Minkowski space. According to FG, the universal gravity force iscaused by exchange of gravitons - the quanta of gravity field. Energy of thisfield is well-defined and excludes the singularity. All classical relativisticeffects are the same as in GR, though there are new effects, such as free fallof rotating bodies, scalar gravitational radiation, surface of relativisticcompact bodies, which may be tested experimentally. The intrinsic scalar (spin0) part of gravity field corresponds to "antigravity" and only together withthe pure tensor (spin 2) part gives the usual Newtonian force. Laboratory andastrophysical experiments for testing new predictions of FG, will be performedin near future. In particular observations with bar and interferometricdetectors, like Explorer, Nautilus, LIGO and VIRGO, will check the predictedscalar gravitational waves from supernova explosions.Comment: 9 pages, to be published in the Proceedings of the 1st Crisis in  Cosmology Conference, AIP proceedings serie
