The Enigmatic Rhythm of Earth's 27 Million Year Pulse
Researchers from New York University and the Carnegie Institution for Science have discovered that Earth has a cyclical pattern of major geological events occurring roughly every 27.5 million years. By analyzing the ages of 89 major geological events over the past 260 million years, they found that these events were clustered at 10 different time points. The next step is to determine the cause of this cycle, with potential links to global tectonics, climate change, and astronomical cycles. The last cluster of events occurred around 7 million years ago, so there is still plenty of time before the Earth's next major geological activity.
