Barry Barish is the Linde Professor of Physics, Emeritus at California Institute of Technology. He is a leading expert on gravitational waves, having led the Laser Interferometer Gravitational-wave Observatory (LIGO) project as the Principal Investigator and Director from the beginning of construction in 1994 until 2005, and he continues to play an active leading role in LIGO.


Albert Einstein predicted the existence of gravitational waves 100 years ago, but the effects are so tiny that even Einstein thought they could never be detected. After 40 years of controversy, theorists finally developed a consensus that they really do exist. Then, the problem became whether experimental physicists could develop instruments sensitive enough to actually detect them? This past year, the Laser Interferometer Gravitational-wave Observatory (LIGO), using exquisitely sensitive techniques, made the dramatic observation of gravitational waves coming from the collision of two Black Holes. This observation has opened a totally new window on the universe.

The lecture is free of charge and open to the public. Registration is not needed. 

The lecture will be published shortly after 11 January at http://KVATV.se.
