TED: The sound the universe makes | Janna Levin

The video explores how most of our knowledge about the universe comes from light, and introduces the idea that the universe has a soundtrack, played by space itself. It delves into Einstein's theories on space and black holes, explaining how black holes can be detected through their gravitational waves. The video discusses the potential to hear cosmic sounds, such as those from black hole mergers and the Big Bang, through advanced experiments like LIGO and Lisa. It concludes by pondering the existence of a multiverse and the possibility of other creatures wondering about their origins.
