On the Cover

The graph shows the 1σ constraints on the density of dark energy and of cosmic matter over time (i.e., red shift) from an analysis of supernova, CMB, and galaxy-clustering data. This analysis indicates that Einstein's model of a constant cosmological "constant" is favored over dynamic dark-energy models which predict either a Big Crunch or a Big Rip within tens of gigayears.
