Researchers from Honauk center for Helmholtz in Potsdam They created a unique sound copy -a sound of a magnetic coup, which occurred about 780,000 years ago (called Matuayama -BhaHaes). This is an event when the magnetic fields become unstable and gradually changing their direction, now it sounds like a terrible sound of an online promotion field. The results were presented at the presentation ESA (European Space Agency)
What is the magnetic field?
The magnetic field of the Earth is created by the metal lines inside the nucleus. It protects the planet from cosmic radiation and sun. When the field is weak and flipped, the higher particles penetrate into the atmosphere, helping to enhance the formation of a isotopes of Beryllium – 10 – it is found in the ice cores, allowing dating with the period of the weak school.
Sanya Panovsk and Ahmed Nasser Mahgub have collected early records from sediment cores around the world and created a global model in the fields of Matuayama -brunhas. Later, artist Maximilian Shanner imagined this data, and DJ Klaus Nielsen and Shanner himself turned to sound.
What can you hear?
Sound is a gradual current of the electromagnetic lines, their decomposition and repetitive fiction of the fusion fusion, accompanied by the bubble of polarization. This is like a chaotic stream of the Earth's magnetic forces, weakened and then restored.
The authors said the audio format created a sense of intuitive, immersed – deeper than the graph – and attracted the attention of a wide object, the authors said.
Why is it important to science?
This approach helps the public and researchers better understand complex geophysical processes. Thanks to this study, the field models were confirmed that global revenue began about 800 matches 780 thousand years ago and took about 30 thousand years. In addition, such models are very important to understand the interaction of climate, geology and magnetic process.
But still unclear
The consequences of this rotation of the magnetic field are not completely clear. Our ancestors – Homo Erectus – survived later, but affected the climate and living creatures were poorly studied. There are very few archaeological data 780,000 years ago, so the relationship between geomagnetic and biosphere events is still hypothesized and continuously studied.
We hear this event as a chase song to set the basis for the appearance of modern people, the researchers summarized.
