On Monday, 14 September 2015, ten years and one day ago, a discovery was made that shook the world.
Shortly before noon Central European time, the first ever gravitational wave from a pair of coalescing black holes was detected by both @LIGO detectors.
Researchers at @mpi_grav were the first to see the signal and made crucial contributions in several key areas.
