Vacuum energy, holography and a quantum portrait of the visible Universe

Abstract

Describing the presently observable Universe as a self-sustained condensate of gravitons of size $H_0^{-1}$, with large occupation number $N$, we argue that the most probable value for the quantum vacuum energy is of the order of the critical energy density, as observed.
