Neil deGrasse Tyson took the stage at Columbia University to speak after a historic result was revealed: the first direct detection of gravitational waves. Columbia University hosts several researchers in the global collaboration working on the detectors, and yesterday the collaborators finally got to reveal that they have measured impossibly tiny variations in timing caused by the merging of two black holes 1.3 billion years ago.
