[交流] 【国外学术报告(视频)】Catching the Waves with LIGO

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is aimed at opening the field of gravitational-wave astrophysics through the direct detection of gravitational waves. LIGO detectors will use laser interferometry to measure the distortions of the space-time between free masses induced by passing gravitational waves. The design, construction, and operation of LIGO is being carried out by scientists, engineers, and staff at the California Institute of Technology (Caltech) and the Massachusetts Institute of Technology (MIT). Caltech has prime responsibility for the project under the terms of a Cooperative Agreementi with the National Science Foundation (NSF). LIGO is a national facility for gravitational-wave research, providing opportunities for the broader scientific community to participate in detector development, observations and data analysis. LIGO welcomes the participation of outside scientists at any of these levels. LIGO has been constructed in a phased approach beginning with one three-interferometer detector system and evolving to improved detector configurations to enable more sensitive gravitational-wave observation systems.


Dr. Barry Barish, the Ronald and Maxine Linde Professor of Physics and director of the Laser Interferometer Gravitational-Wave Observatory (LIGO) Laboratory at Caltech, presented the LIGO project that is being developed to detect gravitational waves that Einstein predicted the existence of in 1916 as a consequence of the general theory of relativity.

Here Barry Barish is giving an online lecture about  LIGO
