Every 26 seconds, Earth emits a faint, rhythmic vibration—inaudible to us, but persistent and global.

First detected in 2005, this tiny pulse repeats with clockwork precision, baffling scientists to this day.

Experts say the pulse rides on ambient seismic noise—energy from waves, winds, and solar-heated storms.

The vibration travels like a knock on a desk—felt across the planet, despite its subtle origins.

It’s not an earthquake. It’s not a storm. And it may not even come from the surface—yet it keeps ticking.

The pulse is offering clues to the Earth’s inner workings—mapping how energy moves through the crust and mantle.

For all our tech—satellites, supercomputers, seismographs—we still don’t know what causes it. But it hasn’t stopped.
