Every 26 seconds, Earth gives off a low-frequency pulse—like a planetary heartbeat.
First detected in the 1960s, this repeating “microseism” comes from somewhere near the Gulf of Guinea. It's not a quake, storm, or machine. It’s natural—but its exact cause? Still unclear.
Scientists believe it may be tied to ocean waves striking the seafloor, sending rhythmic vibrations through the planet’s crust. But despite decades of data and global detection, it remains a mystery hidden in plain rhythm.
The planet pulses. And we’re still listening.
