At first glance, this seems somewhat surprising, and previous theories had not recognized this potentially important connection.&#8221;  <\/p>\n<p>This new assessment is based on the resilience of Earth&#8217;s magnetic field, which is maintained by a rotating and electrically conducting fluid in the outer core, known as a geodynamo.  <\/p>\n<p>Professor Fausto Cattaneo, an astrophysicist at the University of Chicago, said, &#8220;A peculiar property of the Earth&#8217;s dynamo is that it can maintain a strong magnetic field but not amplify a weak one.&#8221;<\/p>\n<p>The scientists therefore concluded that if Earth&#8217;s field were to get switched off, or even reduced to a very small level, it would not have the capability to kick in again. <\/p>\n<p>&#8220;It is this remarkable feature that allows us to make deductions about the history of the early Earth; including, possibly, how the moon was formed,&#8221; added Professor Cattaneo. <\/p>\n<p>Professor Hughes added, &#8220;And if that is true, then you have to think, where did the Earth&#8217;s magnetic field come from in the first place? Our hypothesis is that it got to this peculiar state way back at the beginning, either pre-impact or as an im<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">media<\/a>te result of the impact.
