The sound the universe makes: Janna Levin on TED.com

We think of space as a silent place. But physicist Janna Levin says the universe has a soundtrack — a sonic composition that records some of the most dramatic events in outer space. (Black holes, for instance, bang on spacetime like a drum.) An accessible and mind-expanding soundwalk through the universe. (Recorded at TED2011, March 2011, in Long Beach, California. Duration: 17:43)
