Abstract

We develop a dynamic effective model that accounts for the accelerated expansion of the universe. The model rests on the quantum theory of gravity, which predicts that negative gravitational charges exist. We demonstrate that the outcomes of this model match those of dark energy models and are therefore consistent with observations. We propose that the accelerated expansion of the universe provides observational evidence for the existence of negative gravitational charges. According to this model, a universe filled with negative gravitational charges undergoes accelerated collapse. In addition, we offer an alternative physical interpretation in which the cosmological constant is equivalent to negative gravitational charges acting as a source of gravitational fields. This interpretation sidesteps the fine-tuning problem. The dynamic model predicts that the equation of state, the cosmological constant, and the acceleration of the universe's expansion all vary with time.

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