Earth’s magnetic field dramatically flipped a little more than 40,000 years ago. We can now experience this upheaval as an unnerving clatter interpreted from information collected by the European Space Agency’s Swarm satellite mission.
Combining the satellite data with evidence of magnetic field line movements on Earth, European geoscientists mapped the so-called Laschamps event and represented it using natural noises like the creaking of wood and the crashing of colliding rocks.
The resulting compilation from the Technical University of Denmark and the German Research Center for Geosciences is unlike anything you’ve ever heard.
