Abstract
In the standard cosmological model the dark energy (DE) and nonrelativistic (NR) matter densities are determined to be comparable at the present time, in spite of their greatly different evolution histories. This ‘cosmic coincidence’ enigma could be explained as a non-anthropic observational selection effect: We show that in a suitably chosen frame the Universe is at its most probable epoch when the Hubble radius attains a maximum, at the epoch when the energy densities of DE and NR matter are comparable.
