One of the most modern doomsday scenarios involved the magnetic field of the Earth. It is speculated that one day this will suffer a reverse which will immediately lead to the extinction of the entire planet. However, for the first time, scientists found evidence that this alternative future is not going to happen too soon. A team of experts from the Hebrew University of Jerusalem, the University of California and Tel Aviv University have made a major discovery. They found new method to use ancient pottery to prove prove that the magnetic field has always been fluctuating throughout the course of the history.
People have been able to use the compass for the most accurate orientation thanks to the magnetic field of our Blue planet. There are electric currents and magnetic materials that generate the magnetic effect that protects the atmosphere from solar winds. These are so powerful that scientists believe that they destroyed any signs of life from Mercury and Mars.
However, even after years of studies, there is little known about this phenomenon. Scientists managed to deduce that this has something to do with the dynamic of the molten iron core inside Earth. Moreover, they discovered that constancy is not one of its attributes. The compass is rather pointing to the magnetic north, and every 300,000 years the poles are inverted. As a result, the north becomes south and vice-versa.
This particular reversal is what worries experts. These events are thought not to happen fast enough to avoid an apocalyptic destabilization. During the transition, the magnetic field might disappear. Even if this happens in a split second, it would be enough to leave the Earth unprotected and suffer the consequences of exposure to solar winds.
However, a group of scientists including names from NASA, believe that the records of discovered geological and fossil samples show no evidence of the possibility of such a scenario. Back days, ceramics took the place of today’s plastic objects. This is why people used them abundantly and their material stored precious data throughout the history. For the study, researchers used 67 ancient storage jar handles. Their royal stamps stated exactly to which century their pertain.
By using superconducting magnetometer and paleomagnetic ovens, scientists could calculate the state of the magnetic field at the time of their creation. The results show that the magnetic field is not consistent, and the peak of its fluctuation took place in 8th century BCE. Moreover, there were no signs of any pole reversing phenomenon.
