Why Do Binary Pulsars Reveal That Gravity Takes Time?

Drift into slumber as we explore the subtle dance of gravity, revealed by the steady, predictable pulse of binary stars. This long-form narration, designed to help you relax and fall asleep, gently explains how the gradual decay of these celestial orbits demonstrates that gravitational changes travel at a finite speed, rather than instantly. Over about four hours, we consider how finding the first pulsar, the ledger of arrivals, and a network of clocks all contribute to testing the limits of relativity and understanding the speed of causation. There are no sudden sounds or jarring moments to disturb your rest.
