Abstract

Based on a model of the universe without singularity, it is proven that the energy density of the vacuum state must be zero or a finite and small positive number. Consequently, the effective cosmological constant is easily determined according to the observations.

Keywords:
cosmological constant the energy density of the vacuum state symmetry breaking gravitational mass
