Listening to the Sounds of Space

Listening to the Sounds of Space

Einstein first predicted the existence of gravitational waves 100 years ago. For decades, scientists have been working to capture the sounds of gravitational waves in space, which result from black hole collisions. Janna Levin, author and professor of physics and astronomy at Barnard, details the experiments and machines that are now recording the first sounds from in her latest book, Black Hole Blues and Other Songs from Outer Space.
