Abstract

We examine the possibility that Friedman-Robertson-Walker evolution is governed by an effective (rather than by the actual) energy density. A concrete example is provided by Λ = 0 Regge-Teitelboim cosmology, where critical cosmology only requires subcritical matter density (Ω_matter < 1), and the age of a flat matter-dominated universe gets enhanced by a factor of 9/8. Dual to the mature dilute universe is the embryo universe, the evolution of both is governed by P_eff = - 1/9 ρ_eff.
