Kip Thorne, Rainer Weiss, Barry Barish and Ronald Drever | Smithsonian Magazine’s 2016 American Ingenuity Award Winners for Physical Sciences In February, physicists announced the first-ever detection of gravitational waves—a phenomenon Albert Einstein predicted back in 1915. The faint reverberation, from two merging black holes 1.3 billion light-years ago, registered in the two giant detectors that make up the Laser Interferometer Gravitational-Wave Observatory, or LIGO. It took decades for LIGO’s founders—Weiss, of MIT, and Thorne and Drever, of Cal Tech—to amass the necessary funding and brainpower. Barish, a particle physicist at CalTech, became LIGO’s director and expanded its work to include more than 1,000 researchers worldwide. Their revolutionary achievement opens the way for a new understanding of the universe, perhaps even a glimpse of the Big Bang.
