Tens of thousands of years ago, the Earth’s magnetic field flipped — and now, scientists have recreated the haunting sound it made during that cataclysmic event.
Using data from the European Space Agency’s three-satellite Swarm mission delving deep into our planet’s magnetic field, Danish and German researchers have managed to map and recreate the sounds of what is known as the Laschamp event, which resulted in Earth’s magnetic field briefly flipping 41,000 years ago.
During this event, which was named after the Laschamps lava flows in France where evidence of this flip was first discovered in the 1960s, our planet’s magnetic field weakened to just five percent of its normal strength.
