Dynamics of the universe in the modified unimodular theory of gravity

Abstract

The equations that govern the dynamics of the universe in the modified unimodular theory of gravity are derived. We find a mechanism for inflation in the early universe without postulating a false vacuum state during the first $10^{-35}$ seconds after the Big Bang. In addition, we find a natural explanation for the acceleration of the universe without resorting to dark energy.
