A new scientific evaluation revealed that What would have caused the Earth’s magnetic field was the impact of a large rocka study that would completely change the perspective of the scientific community.
As recalled by a report published on the website of Infobaethat life on our planet has been preserved is due to our geomagnetic field, that force that surrounds the Earth and which is attributed to the combined effect of planetary rotation and the movement of molten iron in its core.
Field protects Earth from cosmic rays that would destroy the outer atmosphereincluding the ozone layer that protects it from harmful ultraviolet radiation.
This study exposes a peculiar property of the magnetic field, which could help us determine how our world formed 4.5 billion years ago.
What do the experts say?
David Hughes, a co-author of the research and an applied mathematician at the University of Leeds, explained in a release that “previous theories had failed to recognize this potentially important connection.”
“The interplanetary collision was so colossal that it created vast amounts of material that they formed the moonaccording to the giant impact hypothesis of the history of the origin of our natural satellite”, he added.
Astronomers had never thoroughly studied the magnetic field hypothesis to understand the formation of the Moon, what would be the key to understand the development of the Earth.
The Leeds scientists and their colleagues at the University of Chicago concluded that Earth’s magnetic field must have formed before the impact or as a result of it.
The researchers say their study can help narrow down theories of Earth-Moon formation, informing future research about what really happened.
Professor Hughes argued: “Where did the Earth’s magnetic field come from in the first place? Our hypothesis is that it got into this peculiar state early on, either before the impact or as an immediate result of the impact. Either way, any realistic model of the formation of the Earth-Moon system must include the evolution of the magnetic field.”.
