Earth's Magnetic Field Strengthens, Boosting Atmospheric Oxygen and Life Potential
TL;DR Summary
NASA scientists have found a correlation between Earth's magnetic field strength and atmospheric oxygen levels over the past 540 million years, suggesting a possible link between deep Earth processes and surface habitability. The study analyzed historical data from minerals and rocks, revealing that magnetic field fluctuations and oxygen levels have followed similar patterns since the Cambrian explosion, potentially influenced by internal planetary dynamics.
