The Possible: Listening to the Universe

More recently, an MIT physics professor did the math and concluded that Einstein was wrong. So he built the Laser Interferometer Gravitational-Wave Observatory (LIGO), which measures almost infinitesimally small disturbances in spacetime - smaller than anything that's been measured before. And in 2016, LIGO succeeded, detecting gravitational waves from a massive, faraway collision between black holes.
