The slow heartbeat of Earth

Even Earth has its own heartbeat.
But through all of that, it seems Earth has been keeping time. A new study of ancient geological events suggests that our planet has a slow, steady 'heartbeat' of geological activity every 27 million years or so.

This pulse of clustered geological events - including volcanic activity, mass extinctions, plate reorganizations and sea level rises - is incredibly slow, a 27.5-million-year cycle of catastrophic ebbs and flows. But luckily for us, the research team notes we have another 20 million years before the next 'pulse'.
