Lambda=0 Cosmology of a Brane-like Universe | | Aharon Davidson
; | | Date: |
1 Oct 1997 | | Journal: | Class.Quant.Grav. 16 (1999) 653-659 | | Subject: | gr-qc astro-ph hep-th | | Abstract: | We examine the possibility that Friedman-Robertson-Walker evolution is governed by an effective (rather then by the actual) energy density. A concrete example is provided by $Lambda=0$ Regge-Teitelboim cosmology, where critical cosmology only requires subcritical matter density $(Omega_{m}<1)$, 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}
