Description: 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.

The sound the universe makes

Space, once thought silent, carries a cosmic symphony, with black holes drumming on spacetime, revealing dramatic events.

Einstein's theory of relativity unraveled space's capability to warp, introducing black holes as universe's enigmatic players.

Emerging tech like LIGO & LISA aims to amplify the universe's whispers, potentially unlocking secrets from the Big Bang itself.
