But so far, those methods have only been able to catch waves at high frequencies, explained NANOGrav member Chiara Mingarelli, an astrophysicist at Yale University. In 2015, scientists used an experiment called LIGO to detect gravitational waves for the first time and showed Einstein was right. Scientists sometimes liken these ripples to the background music of the universe. “It’s really the first time that we have evidence of just this large-scale motion of everything in the universe,” said Maura McLaughlin, co-director of NANOGrav, the research collaboration that published the results in The Astrophysical Journal Letters.Įinstein predicted that when really heavy objects move through spacetime - the fabric of our universe - they create ripples that spread through that fabric. They reported Wednesday that they were able to “hear” what are called low-frequency gravitational waves - changes in the fabric of the universe that are created by huge objects moving around and colliding in space.
