From quantum foam to graviton condensation: The Zel'dovich route
From quantum foam to graviton condensation: The Zel'dovich route
Abstract Based on a previous ansatz by Zel'dovich for the gravitational energy of virtual particle-antiparticle pairs, supplemented with the holographic principle, we estimate the vacuum energy in a fairly reasonable agreement with the experimental values of the cosmological constant. We further highlight a connection between Wheeler's quantum foam and graviton …
