Gravitational waves announcement ushers in new era of multi-messenger astronomy

For the first time, scientists have directly detected gravitational waves in addition to light, from the spectacular collision of two neutron stars. This marks the first time that a cosmic event has been viewed in both gravitational waves and light. Cornell University physicists and experts, who played a vital role in validating the detection of […]

Cornell physicists honored to play vital role in validating detection of gravitational waves

This morning, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics 2017 to physicists Rainer Weiss, Barry C. Barish, and Kip S. Thorne, for “decisive contributions to the LIGO detector and the observation of gravitational waves.” In this video, Kip Thorne talks about the detection of gravitational waves as a guest speaker […]

Cornell astrophysicists play vital role to validate detection of gravitational waves

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 […]

Cornell plays key role surfing for gravitational waves

A full century after Albert Einstein’s Theory of Relativity proclaimed that gravitational waves cause ripples in spacetime, humanity may finally have the tools to detect these waves. The National Science Foundation (NSF) has awarded $14.5 million to the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) consortium over five years to create and operate a […]
