The Expanding Universe: Change of Regime

Section: Astrophysics and Cosmology
Language: English

Abstract: The aim of the paper is to explain, on the basis of the strict equations of quantum geometrodynamics for a cosmological model with the Robertson–Walker metric, the possible change of a regime of the expansion of the universe, from acceleration to deceleration or vice versa. We show that the change of the rate of expansion can point to the existence of a particular type of forces acting in the universe. It is indicated that these forces have the quantum nature. The cause of the expansion and a change of its regimes is a special form of the effective potential well, in which the universe is moving as a whole.

Key words: dark energy, dark matter, quantum geometrodynamics, cosmology.
