Perhaps we should rethink the composition of the Earth

We know that the Earth was formed by the agglomeration of dust and large rocks attracted by gravity. However, many hypotheses regarding this process remain to be verified. A recent study sheds light on certain details of the mechanism.

Have you ever imagined how the Earth and the moon formed? Scientists always tried to find a file A rational explanation for this phenomenon. From where, the birth of the giant impact hypothesis according to which the moon was the fruit of a collision Between the boy of the earth and protoplanet Similar to the size of Mars. Today, scientists have made a breakthrough in their research on this topic. The latest studies revealed that it is possible to explain the formation of the Earth through Earth’s magnetic field.

But when did the earth begin to become magnetized?

The University of Leeds researchers and one of Chicago conducted a study on The dynamics of fluids and electrically conducting fluids. This analysis allowed them to determine when the Earth began to magnetize, that is, before or after the impact. In this way, scientists intend to refine disparate theories about the formation of the Earth.

according to David Hughesa Professor of Applied Mathematics at the University of LeedsTheorists of the time downplayed the importance of this link. However, according to him, it will occupy a dominant position in I’History of the Earth and Moon System.

A theory based on the specific property of geodynamo

The earth dynamoalso called Geodynamois a circulating, electrically conductive fluid found in blue planet core. that you serve To drive many magnetic field lines. This movement is caused by the rotation of the Earth.

According to confirmation Fausto CattaneoAnd the Professor and astrophysicist at the University of ChicagoEarth’s dynamo “It can maintain a strong magnetic field, but it does not amplify a weak field”. So if she has to go outside, it will not be able to activate automatically. In this sense, scientists are trying to understand Formation of the Earth-Moon system. Thus, the question here is whether or not the primordial Earth was actually magnetized.

Extensive research on the evolution of magnetic fields

The Teacher Hughes Encourages scientists to do more research on The origin and evolution of magnetic fields.

” And if this is true, you must be wondering where the magnetic field comes from in the first place.. »

Professor Hughes

Moreover, according to him, the history of the Earth must necessarily include the study of magnetism. Then, how to confirm elastic magnetic field If we do not talk about its origin and special characteristics? In any case, the researchers already have their hypothesis about it. The defining characteristic of the magnetic field will be a The direct result of the effect Or maybe his condition before the collision.
