A little more than a hundred years ago, Albert Einstein worked out a consequence of his new theory of gravity: Much like waves traveling through water, ripples can undulate through space and time, distorting the fabric of the universe itself.
Today, Rainer Weiss, Barry C. Barish and Kip S. Thorne were awarded the 2017 Nobel Prize in Physics for decades of work that culminated in the detection of gravitational waves in 2015—and several times since—by the Laser Interferometer Gravitational-Wave Observatory (LIGO).
Emily and Chris sat down with UMD physics professor Peter Shawhan, a member of the LIGO collaboration, to learn more about gravitational waves and hear a sliver of the story behind this year's Nobel Prize.
