  • Gravitation Flat Power Field

    Gravitation – Flat Power Field S.A. Orlov A new principle of origin and the nature of the action of gravity forces are proposed. Forces of universal attraction have plane-symmetrical directions. On this basis, it becomes possible to reconsider certain regularities in natural science. The new principle of gravitation will allow to explain physical paradoxes, to improve methods of scientific research and some technological processes. Keywords: Theory vortex gravitation, cosmology and cosmogony. Celestial mechanics
