We time an array of ultra-precise millisecond pulsars with the world's largest radio telescopes. We use this network of cosmic clocks to measure invisible ripples in spacetime produced by extremely massive black holes. Our transformative experiment will reveal unique insights into how galaxies have grown over cosmic time.
