Einstein’s Ears: The New Astronomy of Gravitational Waves
Speaker: Scott A. Hughes (MIT, USA)
ABSTRACT: In Einstein’s general relativity, gravity radiates. Because gravity is the weakest fundamental force, Einstein believed this radiation would never be measured. He was wrong. In the past several years, an international collaboration has not only directly measured gravitational waves produced by exotic astronomical objects, but used them to develop a new form of astronomy. In this lecture, I will describe the quest for gravitational waves, showing how this idea emerged as over the centuries we have improved our understanding of gravity’s nature. I will emphasize that it is best to think of these waves as “sound-like,” and will play examples of the songs that astronomical objects sing as I describe this new astronomy.
