TED: What does the universe sound like? A musical tour | Matt Russo

The video explores the connection between music and astronomy, starting with the idea of hearing stars and constellations. It delves into the historical link between music and astronomy, highlighting Pythagoras' theories. The TRAPPIST-1 exoplanetary system is examined for its musical harmony, contrasting it with the dissonant sounds of our solar system. The video concludes with a project called 'Our Musical Universe,' which offers an audio tour of the cosmos, making it accessible to those with vision loss.
