Can we hear the universe? Exploring the ancient and modern music of the spheres.
In short: Professors Chris Lintott and Milton Mermikides examine how astronomers and musicians have long linked celestial movement to musical harmony. This lecture demonstrates how historical theories of cosmic sound evolve into modern astro-sonification, turning data from black holes and exoplanets into audible patterns.
The lecture traces the intellectual lineage of cosmic harmony, beginning with Pythagoras’s connection between tuning purity and celestial motion, and Plato’s concept of cosmic order in Timaeus. It further explores Johannes Kepler’s efforts to map orbital eccentricity onto musical scales, alongside William Herschel’s integration of music and cosmology. These historical frameworks provide context for the modern scientific practice of astro-sonification.
Today, researchers use sound to analyze and communicate complex astronomical phenomena. By converting data—such as black hole radiation or the characteristics of exoplanetary systems—into audio, scientists can identify patterns that might otherwise remain hidden. The lecture highlights how stable planetary systems naturally gravitate toward harmonic ratios, bridging the gap between mathematical physics and musical expression.
