Grøn Ø., Can a dust dominated Universe have accelerated expansion

By Morad Amarzguioui and Øyvind Grøn

Abstract

Recently, there has been suggestions that the apparent accelerated expansion of the universe is due not to a cosmological constant, but rather to inhomogeneities in the distribution of matter. In this work, we investigate the behavior of the dust dominated inhomogeneous Lemaître-Tolman-Bondi universe models, and show that they do not permit accelerated cosmic expansion. Subject headings: inhomogeneous universe models, accelerated cosmic expansion 1
