A team of researchers working at Stanford University has used time dilation in an atomic fountain to measure the curvature of space-time. In their study, reported in the journal Science, the group used the fountain as an interferometer to measure atomic wave packet changes that corresponded to phase shifts. Albert Roura,with the German Aerospace Center's Institute of Quantum Technologies published a Perspective piece in the same journal issue outlining the work by the team in California.
