Scientists recreate the sound of Earth's magnetic field flipping 41,000 years ago

Earth's magnetic field dramatically flipped 41,000 years ago, and scientists have now created an eerie audio representation of this event. The sound was generated by combining European Space Agency satellite data with evidence of magnetic field line movements, mimicking natural noises like creaking wood and colliding rocks. This reversal, known as the Laschamps event, weakened the magnetic field, potentially allowing more cosmic rays to reach Earth and impacting climate and megafauna extinctions.
