A new scientific study suggests that the Earth’s inner core recently stopped spinning and began to spin in the opposite direction. It is also stated that the changing direction of rotation may also have a relationship with the day lengths that fluctuate from year to year. However, this change is not expected to negatively affect people and the planet.Earth’s core began to spin in the opposite direction
In the January 2023 issue of the scientific journal Nature Geoscience, researchers from Peking University, China, claimed that the planet’s inner core stopped spinning around 2009 relative to other layers and started spinning in the opposite direction. As far as is known, the innermost part of the earth is located approximately 5,000 kilometers below our feet. Made of hot iron and about the size of Pluto, this core can rotate independently of the mantle and crust due to a liquid outer layer surrounding it.
Happens every 35 years
“We believe that the inner core rotates back and forth like a ‘swing’ relative to the Earth’s surface. One cycle of the swing changes direction for about 70 years, that is, every 35 years on average.” uses expressions.In the study carried out by Chinese scientists, seismic waves from earthquakes of the last sixty years were analyzed in order to follow the movements of the inner core. A similar pause and reversal occurred in the early 1970s, according to the data. The next one is expected in the 2040s. The study group examining the data found a similar relationship between the early 1970s and the current period.
John Vidale, a seismologist at the University of Southern California, however, disagrees with this study. Vidale thinks that the models created do not fully explain the available data. There are multiple theories about the Earth’s central core, and there is no consensus among scientists yet. Because what is available is actually all seismic data. Therefore, we can obtain limited information about what is going on inside the Earth.
