On the Universe curvature
Keywords:
cosmology, Universe curvature, gravitational viscosity, red shiftAbstract
It is shown that the Universe is not a conservative system. This property manifests itself physically as the resistance to the material bodies motion, which is called gravitational viscosity, and as the decrease of the light frequency with distance, which is known as red shift, i.e. as loss (seattering) of energy. On the geometrical point of view, this property manifests itself as the geodesic curvature of the Universe. The general Galileo transformations are given and it is shown that the new equation of the free motion of the material body is invariant with regard to these transformations.
