“So you want to build a machine that you don’t know will work, to find something that may or may not exist.” The story of this year's #NobelPrize in Physics begins three decades ago with Walter Massey's efforts to bring the then-controversial #LIGO #GravitationalWaves project to life. Massey is attending the Nobelprize_org ceremony as a guest of new laureate Kip Thorne.
