The Cosmological Constant

Living Rev Relativ. 2001;4(1):1. doi: 10.12942/lrr-2001-1. Epub 2001 Feb 7.

Abstract

This is a review of the physics and cosmology of the cosmological constant. Focusing on recent developments, I present a pedagogical overview of cosmology in the presence of a cosmological constant, observational constraints on its magnitude, and the physics of a small (and potentially nonzero) vacuum energy.

Keywords: cosmological constant; cosmology; vacuum energy.
