Halloween horror! Listen to demonic sounds that the Earth’s magnetic field creates as it rotates

The Earth’s magnetic field flipped tens of thousands of years ago, and now we know what that might have sounded like. It was only for a short time, but it fascinated researchers. The event known as the Laschamp event resulted in a reversal of the Earth’s magnetic field 41,000 years ago.

Danish and German researchers used data from the European Space Agency’s three-satellite Swarm mission to delve deep into our planet’s magnetic field. The research helped them map and recreate the sounds of the Laschamp event.

Evidence of this reversal was first discovered in the 1960s at the Laschamps lava flows in France and was therefore named after it. During this event, our planet’s magnetic field weakened to just five percent of its normal strength.

A lot of cosmic radiation passed through the atmosphere. Researchers from the Technical University of Denmark and the German Research Center for Geosciences show in their replica that it made a terrible noise.

The Scandinavian researchers used field recordings of different things, like the creaking of wood and falling rocks, and mixed them together to create the eerie sounds of the planet’s magnetic field shifting.

Listen to the alien sounds

This is the first time we hear the sounds of the magnetic field reversing. However, scientists have previously created a soundtrack of the magnetic field using data from the Swarm mission.

In October 2022, ESA and the Tech University of Denmark released an audio recording showing what our modern magnetic field sounds like. That was just as frightening.

As with the current replica, researchers used regular sounds to show what the Earth’s magnetic field sounded like during solar storms.

“The rumbling of the Earth’s magnetic field is accompanied by the depiction of a geomagnetic storm that resulted from a solar flare on November 3, 2011,” said Klaus Nielsen, supporter of the TUD musician project, in a statement in 2022. “Indeed it sounds pretty scary.”

On Halloween, they scared people by playing the sound through 32 underground speakers in Solbjerg Square in Copenhagen.
