The inner core of the Earth is a hot, dense ball of solid iron located more than 5,000 kilometers deepbeing the most inaccessible place on our planet and which has been debated for decades. It should be remembered that the deepest we have drilled is about 12 kilometers.
Our planet rotates in space and so does the core, although it can do so independently. Thanks to this rotation, it generates a magnetic field due to its metallic composition, through which the Earth is protected from solar winds, for example, and is also responsible for compasses guiding us.
However, a scientific team has observed that the inner core has begun to slow downspecifically, from 2010. It now moves more slowly than the Earth’s surface.
The study carried out by the University of Southern California (USC) and published in Natureassures that this phenomenon is the first time it has happened in 40 years and could alter the length of the day.
According to John Vidale, a professor of the study, the slowing of the inner core occurred due to the agitation of the surrounding outer core. Research has suggested that this change may cause the length of a day is 25 hours.
Yes indeed, in a period of about 200 million years, as noted in another analysis from the Technical University of Munich (UTM). A barely perceptible modification for human life and that is not catastrophic at all.
