The 100 year Odyssey from Einstein to Gravitational Waves- Dr. Barry C Barish, Caltech-LIGO

Event date and time

Thursday, September 21, 2017 - 3:00pm to 4:15pm

Description

Abstract: Albert Einstein predicted the existence of gravitational waves 100 years ago ven 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? The Laser Interferometer Gravitational-wave Observatory (LIGO), using exquisitely sensitive techniques, has made the dramatic observations of gravitational waves coming from the collision of two Black Holes. These observations have opened a totally new window on the universe. The history, techniques and initial observations will be discussed.
