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