An international project mapping millions of galaxies could reshape our understanding of the history of the universe, according to University of Queensland astrophysicist Tamara Davis. The 10-year global project studied exploding stars (supernovae) in night skies, the results of which indicate the universe might be 100 million years younger than previously thought. "The best-accepted model of the Universe has a background acceleration, called dark energy, that doesn’t change," Prof Davis said. "Our results suggest the acceleration might actually be weakening, which would mean the Universe might also be a tiny bit younger than previously thought — by 100 million years or so."
