Abstract

The Cosmological Constant Λ within the modified form of the Einstein Field Equation (EFE) is now thought to best represent a ?dark energy? responsible for a repulsive gravitational effect, although there is no accepted argument for its magnitude or even physical presence. In this work we compare the origin of the Λ argument with the concept of unimodular gravity. A metaphysical interpretation of the Poisson equation during introduction of Λ could account for the confusion.
