Scientists have now recorded the eerie sounds of the Laschamp event, a time when Earth's magnetic field dramatically weakened, permitting cosmic rays to flood our atmosphere.
The captured soundscape represents a time when Earth’s magnetic field was only five percent of its current strength, revealing how our planet may react to magnetic field shifts.
Data reveals the Earth's North and South magnetic poles flip roughly every 200,000-300,000 years, meaning we could be overdue for another magnetic event.
Professor Roberts emphasized that Earth's magnetic field acts as a shield against solar radiation, which remains a concern even today due to potential solar storms.
