The Sound of the Universe

Off topic – but this is an amazing video from TED.  Janna Levin talks about the sound of the universe

I love the way she describes the universe as having a soundtrack, ringing out a recording onto the universe. The evocative image of black holes banging on the drum of space, squeezing and stretching space and slowing down clocks and time.

Mind boggling…but her talk totally captures the imagination
