Archaeological discovery reveals a radical change in the Earth's magnetic field

I wrote in environment he

Scientists have recently discovered an interesting chapter in the history of… Earth's magnetic fieldWhich reveals a major change that has almost taken place 3 thousand years. The discovery, which came from the analysis of clay bricks made in ancient Mesopotamia, provides valuable insights into the ancient civilisation intensity Earth's magnetic field in the period between 1050 and 550 BC.

The Earth's magnetic field, often considered… “protective bubble”, is generated in the core of the planet, a high-temperature mass consisting mainly of iron and nickel. The outer part of the core is liquid, while the inner part is solid. It is the movement of this liquid metal mass that generates the Earth's magnetic field.

The phenomenon discovered by scientists included a Fast and intense strengthening of the magnetic field, which occurs over a few decades. Matthew Howland, one of the researchers involved in the study, explained in an interview with CNN, that the analysis of man-made clay and ceramic bricks has become Crucial for understanding magnetic field changes over timeEspecially in periods when rock analysis is not possible.

What is the importance of the magnetic field?

The Earth's magnetic field plays a vital role in protecting the Earth from… Solar radiation. It's like shieldscattering charged particles from the solar wind and to forbid Until these molecules reach Earth's atmosphere. Without this protection, solar radiation can damage the ozone layer and have harmful effects on life on Earth.

Possible consequences of failure in the magnetic field

Despite the complete failure of the magnetic field It is unlikelyScientists have studied possible catastrophic scenarios associated with a significant decrease in intensity. Among the possible consequences are:

Exposure to solar radiation: As the magnetic field weakens, the Earth will be more exposed to solar radiation. This can increase the risk of cancer due to direct exposure to higher levels of radiation.

Impact on communications: Magnetic interference can affect satellites and communications systems, leading to disruption of telephone and Internet networks, in addition to harming the Global Positioning System (GPS).

Risks to marine life: Some marine species, such as whales and dolphins, use the Earth's magnetic field for navigation. Any major failure could disorient these animals, affecting their migration patterns and behaviour.

Twilight is out of control: Auroras, which are usually restricted to the polar regions due to the magnetic field, can become visible at low latitudes, providing a spectacular sight but indicating significant changes in the magnetic field.

Scientists warn that although the disaster scenarios are theoretical,… Continuous understanding Changes in the magnetic field are crucial to Predict and mitigate potential impacts. The study of bricks in Mesopotamia provides a valuable piece of the puzzle, allowing fundamental insight into the events that shaped the Earth's magnetic field over the centuries.
