The Absence of Gravitational Deceleration during the Expansion of the Universe with increasing Mass

Abstract

It is demonstrated that the total mass of the universe is linearly increasing with time. As a consequence, a mass moving radially with the expanding universe is not decelerated, because it finds itself, during its movement, at the same gravitational potential. The mass variation eliminates the differences between a relativistic and a Newtonian approach to describe the universe expansion, leading to final coincident equations. The principal cosmological parameters (age, size and mass of the Universe, Hubble constant) have been calculated from the microwave background radiation with an accuracy of ± 0.12 per cent. The cosmological constant and the curvature of the universe result to be null. Also the parameters of the primordial universe have been theoretically calculated with the same accuracy of the Planck length. It is suggested that it may be possible from the developed model to calculate the time of appearance of elementary particles. The mass of the particles constituting the dark matter and the time of their appearance have been estimated from the ratio dark/total matter.
