A Dynamic Model of Accelerated Expansion of Universe

Abstract

We establish a dynamic effective model for explaining the accelerated expansion of the universe. The model is based on the quantum theory of gravity that predicts the existence of the negative gravitational charges. We show that the results of this model are equivalent to that of the dark energy models, and therefore, consistent with the observations. We suggest that the accelerated expansion of the universe is an observational evidence of the existence of the negative gravitational charges. This model predicts that the universe filled with negative gravitational charges is accelerated collapse. Moreover we propose an alternative physical interpretation that the cosmological constant is equivalent to the negative gravitational charges as a source of gravitational fields. This interpretation avoids the fine-tuning problem. This dynamic model predicts that the equation of state, the cosmological constant and the acceleration of the expansion of the universe are time dependent.

Keywords: dark energy, cosmological constant, negative gravitational charge, repulsive gravitational force, accelerated expansion of the universe.
