Einstein's Dark Energy Accelerates the Universe

The genius of Albert Einstein, who added a "cosmological constant" to his equation for the expansion of the universe but later retracted it, may be vindicated by new research published today in the journal Astronomy and Astrophysics.
The enigmatic "dark energy" that drives the acceleration of the Universe behaves just likeEinstein's famed cosmological constant, according to the Supernova Legacy Survey (SNLS),an international team of researchers in France and Toronto and Victoria in Canada,collaborating with large telescope observers in Oxford, Caltech and Berkeley.
Their observations reveal that the dark energy behaves like Einstein's cosmological constant to aprecision of 10%. "The significance is huge," said Professor Ray Carlberg of the Department of Astronomy and
Astrophysics at the University of Toronto. "Our observation is at odds with a number oftheoretical ideas about the nature of dark energy that predict that it should change as theuniverse expands, and as far as we can see, it doesn't."
