What sound does the universe make?

Did you know the universe has a constant background hum? It's not a sound you can hear with your ears, but a faint vibration in the very fabric of spacetime, and we've finally detected it. This Short reveals the incredible story of the gravitational wave background. Think of it as the combined echo of every pair of supermassive black holes that have ever merged across the entire history of the cosmos. Each collision sends out ripples in spacetime, and together, they create a persistent, low-frequency hum. We'll explain how scientists use pulsars—the universe's most precise clocks—to 'listen' for this cosmic hum. This groundbreaking discovery gives us a brand new way to study the universe's most massive and mysterious objects. If you're curious about the hidden music of the cosmos, you'll love this journey into the sound of spacetime.
