A scale-dependent cosmology for the inhomogeneous Universe

Abstract

A scale-dependent cosmology is proposed in which the Robertson-Walker metric and the Einstein equation are modified in such a way that Ω0, H0 and the age of the Universe all become scale-dependent. Its implications on the observational cosmology are discussed. ∗E-mail cwkim@jhuvms.hcf.jhu.edu †E-mail thlee@jhup.pha.jhu.edu ‡E-mail jhsong@rowland.pha.jhu.edu
