This Terrifying Sound Of Earth's Magnetic Field Flipping Will Give You Nightmares

About 41,000 years ago, Earth’s magnetic field briefly flipped in what is known as the Laschamp event. Now, a group of scientists using data from the European Space Agency’s (ESA) Swarm mission have recreated the sound the event made, and it is sounds like something straight out of a Hollywood horror film.

According the ESA, Earth’s magnetic field is a complex and dynamic bubble that keeps humans safe from cosmic radiation and charged particles carried by winds from the Sun. When these particles slam into Earth’s magnetic field, the interaction produces the gorgeous blue-green light that is often typical of the aurora borealis. While being able to view the aurora, sometimes as far south as Florida, hearing it is another thing.

The Laschamp event that was recreated happened during a time Earth’s magnetic field was weakened significantly, dropping to a minimum of 5% of ...
