For 540 million years, Earth’s magnetic field and atmospheric oxygen levels have danced in sync — and NASA scientists just uncovered the rhythm. This groundbreaking discovery reveals a powerful link between the planet’s deep interior and the surface conditions that allow complex life to thrive. By analyzing ancient rocks, researchers found that shifts in Earth’s magnetic shield align with changes in oxygen levels, dating back to the Cambrian explosion. Could Earth’s core be the hidden conductor of life?<br />WooGlobe Ref : WGA656503<br />For licensing and to use this video, please email licensing@wooglobe.com
