Earth Has A Mysterious 'Heartbeat' Every 27 Million Years

Over the previous 260 million years, Pangea split into continents and islands, dinosaurs came and went, and humans have rapidly and irreversibly changed our globe.

Despite this, Earth appears to have kept time. Ancient geological event research shows that Earth has a steady "heartbeat" of geological activity every 27 million years.

The extremely slow cycle of volcanic activity, mass extinctions, plate reorganizations, and sea level rises lasts 27.5 million years and has catastrophic ebbs and flows. After 20 million years, researchers expect the next "pulse." This helps us.

The scientists analyzed 89 geological events from 260 million years ago. The graph below shows tough periods when more than eight transformative events occurred within geologically tiny time spans, forming the catastrophic "pulse."

For years, geologists have considered geological cycles. Scientists believed the geological record cycled 30 million years in the 1920s and 1930s. In the 1980s and 1990s, scholars used the latest geological event dates to compute a 26.2 to 30.6 million-year interval between 'pulses'.

Everything is fine; 27.5 million years is about right. Late 2020 research by the same scientists hypothesized that mass extinctions occur at 27.5 million years.

In their 2018 publication, two University of Sydney academics investigated the carbon cycle and plate tectonics and estimated its lifespan at 26 million years.

Collins explained that their most recent study studied many causative occurrences, or those in which one directly causes the other. Therefore, some of the 89 occurrences analyzed are connected, such as marine extinction from anoxic episodes.

Further research by Rampino and his team suggests comet strikes are the culprit, with one space expert even suggesting Planet Nine. If the Earth has a geologic "heartbeat," it may be localized.
