Standard Cosmology Delayed (1106.6231v2)
Published 30 Jun 2011 in gr-qc, astro-ph.CO, hep-ph, and hep-th
Abstract: The introduction of a delay in the Friedmann equation of cosmological evolution is shown to result in the very early universe undergoing the necessary accelerated expansion in the usual radiation (or matter) dominated phase. Occurring even without a violation of the strong energy condition, this expansion slows down naturally to go over to the decelerated phase, namely the standard Hubble expansion. This may obviate the need for a scalar field driven inflationary epoch.
