Lecture: Janna Levin: The sound the universe makes

Lecture: Janna Levin: The sound the universe makes (17:44) 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.) This is an accessible and mind-expanding soundwalk through the universe.

Dr. Levin is a professor of physics and astronomy at Barnard, where she studies the early universe, chaos, and black holes.
