Speaker：Prof.Barry Barish （California Institute of Technology） 

Moderator: Prof. GAO Jie

Time: 14:00, November 8 

Place: Room 214, IHEP Main Building 

Abstract： 

Einstein predicted the existence of gravitational waves one hundred years ago. They have been recently observed from pairs of merging Black Holes by the Laser Interferometer Gravitational-wave Observatory (LIGO). The physics of gravitational waves, the detection technique, the observations, including latest results, and implications will all be discussed.
