Hidden Patterns in Geological Time Revealed: Earth's Variability Saturates at a Half-Billion Years, Study Finds

Hidden patterns in geological time revealed: Earth's variability saturates at a half-billion years, study finds

A new international study published in Earth and Planetary Science Letters reveals that the boundaries between geological epochs and periods, even though randomly distributed, follow a hidden, hierarchical pattern. Co-authored by Prof. Andrej Spiridonov from Vilnius University (VU) Faculty of Chemistry and Geosciences, the research shows that these time boundaries cluster in a way that reflects Earth's system's deepest fluctuations. This finding…

Hidden order uncovered in geological epochs across Earth's deep history

Berlin, Germany (SPX) Aug 25, 2025 A new international study published in Earth and Planetary Science Letters reveals that geological epochs and periods, while seemingly random, actually follow a hidden hierarchical structure. The work, co-authored by Prof. Andrej Spiridonov of Vilnius University, suggests that the timing of major planetary shifts reflects the deepest fluctuations of Earth's system. "Geological time scales
