Scientists Discover , Traces of Massive , Gravitational Waves.<br />Scientists believe they have found signs of an elusive <br />type of rumbling through space that could signal <br />the largest, most powerful black holes in the universe.<br />NPR reports that the discovery could lead <br />to the unraveling of mysteries that <br />surround supermassive black holes.<br />These enormous black holes, millions to billions <br />of times more massive than our sun, exist at <br />the center of galaxies much like the Milky Way.<br />Astrophysicist Stephen Taylor serves as the chair of a team <br />of researchers known as the North American Nanohertz <br />Observatory for Gravitational Waves (NANOGrav).<br />We've been on a mission for the last <br />fifteen years to find a low-pitched hum <br />of gravitational waves resounding <br />throughout the universe, Stephen Taylor, Vanderbilt University astrophysicist, via NPR.<br />We're very happy to announce <br />that our hard work has paid off, Stephen Taylor, Vanderbilt University astrophysicist, via NPR.<br />We expect the gravitational wave <br />evidence that we've seen in this <br />15-year dataset to be even <br />stronger in that one, Maura McLaughlin, NANOGrav astrophysicist <br />at West Virginia University, via NPR.<br />NPR reports that similar research groups <br />around the world have also begun <br />to detect hints of these waves. .<br />The discovery of gravitational waves in 2015 came <br />almost 100 years after being predicted by Einstein.<br />The discovery of gravitational waves in 2015 came <br />almost 100 years after being predicted by Einstein.<br />The NANOGrav team reportedly hopes <br />their work allows researchers to locate <br />and study the source of gravitational waves.
