The LIGO and Virgo gravitational wave detectors carried out the first half of their third observing run from April through October, 2019. During this period, they collected 39 new detections of compact binary coalescences, which were compiled in the second LIGO-Virgo catalog (GWTC-2). These and previously detected signals contain invaluable information about the nature of black holes and the properties of spacetime more generally. In this talk, I will summarize results along this front. This includes updated constraints on deviations from the predictions of general relativity for the generation and propagation of gravitational waves, searches for echos, and probes of the behavior of ringing black holes. I will close by outlining future prospects for testing Einstein’s theory with gravitational waves.
