We address the ~122 orders of magnitude discrepancy between the vacuum energy
density at the cosmological scale and the vacuum density predicted by quantum field theory. This disagreement is known as the cosmological constant problem or the
‘vacuum catastrophe’. Utilizing a generalized holographic model, we consider the total mass-energy density in the geometry of a spherical shell universe (as a first order approximation) and find an exact solution for the currently observed critical
density of the universe. We discuss the validity of such an approach and consider its implications to cosmogenesis and universal evolution.
