That discrepancy could hint at “new physics” beyond the standard model of cosmology, according to the team, which includes physicists from the University of California, Davis, that made the observation.&nbsp;</p> January 26, 2017 - 5:01pm Andy Fell /news/astronomers-measure-universe-expansion-get-hints-new-physics
