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.
