Signal from the Earth's interior. Geophysicists have published eerie sounds
According to researchers, this is the result of chaos that sometimes occurs in the Earth's core. In the outer part, the position of the magnetic pole changes, while in the inner part everything remains the same. As a result, the magnetic field "goes crazy" and becomes extremely weak for hundreds of years.
Note that the position of the Earth's magnetic poles changes on average every 450,000 years. Scientists see this in the way atoms of iron and other magnetic elements are arranged in ancient rocks. Incidentally, the physics of the Earth now contradicts its geography. The planet's South Pole is in the North, and the North is in the South Pole.
Geomagnetic declination is characterized by the fact that after a short-term disturbance, the poles return to the same position they were in before the shift. As paleontologists have established, this is exactly what happened about 41,000 years ago.
The photographs of this event were recreated using data from the Swarm satellite, which studies the Earth's magnetic field. And to convey the scale of this global process, they decided to "sound" the "madness" of the planet's magnetic field lines. To do this, they used, among other things, the real sounds of creaking trees or falling rocks.
Interestingly, these changes weakened the Earth's magnetic field to about 5% of its current strength. Analysis of ancient rocks shows that this destroyed the ozone layer of the atmosphere and turned huge areas into deserts. Remember that the planet's magnetic field protects it from cosmic radiation. Without it, life on Earth would be impossible.
