Space is not silent; it has a complex sonic soundtrack

The sound the universe makes - Janna Levin · 17:44 · Video: TED-Ed · Watch at the source

In short: While we experience the vacuum of space as a void of silence, physicist Janna Levin reveals that the universe actually possesses a distinct sonic composition. This video explores how dramatic celestial events create a literal soundtrack to our cosmos.

The presentation takes listeners on a 'soundwalk' through outer space, translating physical phenomena into audible experiences. For example, Levin describes black holes as objects that 'bang on spacetime like a drum.'

By converting these cosmic movements into sound, the video helps visualize and experience some of the most dramatic events in the universe, moving beyond our human inability to hear them directly.
