Honor Harger: A history of the universe in sound

The video explores the concept of space sounds, contrasting our visual understanding of space with the lesser-known auditory aspect. It highlights how radio astronomy allows us to 'listen' to celestial bodies, providing examples of sounds from the Sun, Jupiter, and Saturn. The video recounts historical anecdotes, including Thomas Watson's accidental discovery of solar radio waves and Karl Jansky's identification of celestial radio emissions. It concludes with Penzias and Wilson's discovery of cosmic microwave background radiation, providing evidence for the Big Bang.
