Since 1916 when Einstein predicted the existence of gravitational waves—the powerful aftermath occurring when black holes collide—scientists have been trying to provide evidence of this profusion of energy. However, a telescope cannot record this event—the only evidence is the sound of spacetime ringing. Janna Levin, one of today’s most eminent theoretical astrophysicists and an award-winning writer, recounts the fascinating story of the surprises, disappointments, achievements, and risks of the scientists who embarked on an epic endeavor to capture the first sounds from space in her latest book, Black Hole Blues and Other Songs from Outer Space. Join us as Levin explores this radical scientific campaign to record the soundtrack of our universe with cosmologist Sean Carroll.
