Dark-Energy Dynamics Required to Solve the Cosmic Coincidence

Chas A. Egan, Charles H. Lineweaver

Dynamic dark energy (DDE) models are often designed to solve the cosmic coincidence (why, just now, is the dark energy density $ρ_{d e}$ , the same order of magnitude as the matter d…

The Cosmic Coincidence as a Temporal Selection Effect Produced by the Age Distribution of Terrestrial Planets in the Universe

Charles H. Lineweaver, Chas A. Egan

The energy densities of matter and the vacuum are currently observed to be of the same order of magnitude: $(Ω_{m 0} \approx 0.3) \sim (Ω_{Λ0} \approx 0.7)$ . The cosmological windo…
