NEWSPAPER 92

The graph shows the 1 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.
