Bing Zhang (Physics & Astronomy) and Xuefeng Wu, former 51³Ô¹ÏºÚÁÏ postdoctoral research associate now with Purple Mountain Observatory, China, and He Gao, a 51³Ô¹ÏºÚÁÏ Ph.D. graduate now at Beijing Normal University, China, recently published a paper in to test Einstein’s weak equivalent principle using gravitational waves. The paper is led by Wu and Gao with Zhang being one of the eight coauthors. The authors suggested that by using gravitational waves recently detected by the Laser Interferometer Gravitational-Wave Observatory and possible electromagnetic counterparts they may be associated with, one can make an unprecedented stringent test on Einstein’s weak equivalence principle, which is the fundamental postulate of Einstein’s general theory of relativity.
