Saul Teukolsky, Cornell University (IMAGE) Cornell University Caption Cornell physics and astrophysics professor Saul Teukolsky has been using supercomputers to solve Einstein's equations for black hole mergers for much of his career. Teukolsky and the Cornell-founded Simulation of eXtreme Spacetimes (SXS) collaboration group have been calculating and completing a full catalog of theoretical solutions since 2000, when supercomputers first became capable of the task. The LIGO and Virgo group confirmed that the waves came from a black hole merger by comparing their data with a theoretical model developed at Cornell.
