On the cosmological vacuum and dark energy


A degenerate fermionic vacuum population is suggested. Based on the abundance of the dark energy density in the Universe the vacuum particle mass and number density are estimated. The obtained mass is in reasonable agreement with observations and predictions of the neutrino mass. The contemporary vacuum turns out quite dense being in the state of a degenerate Fermi fluid with zero sound propagating at the speed of light. This state has been maintained constant at least for the entire observational epoch after inflation.
