Scientists suggest that Earth’s core is stationary and may rotate in the opposite direction

According to research published in the scientific journal nature geology, return earth core it’s been slowing down since it started stalling in 2009 and may now be moving in the opposite direction. Scientists note that seismic records have changed over the years due to movement, but this time around, there seems to be little difference between events that have occurred in recent years.

Our planet’s core has a radius of about 3,500 kilometers and is almost the same size as Mars, located 5,000 kilometers below the earth’s crust – iron and nickel are the most abundant materials at the center of planet Earth, and they move like rivers. In fact, new research led by researchers at Peking University in China indicates that some natural disasters may have been caused by this rotation change.

As the scientists explain, this reversal cycle can take 70 years and affect the length of days on Earth. But rest assured, it’s just a few seconds less a day, and yet some scientists are skeptical of this shift. Using information from seismic events to try to understand the change, the researchers also suggested that a giant catastrophe would not happen—it’s not an apocalyptic event.

“We’re seeing strong evidence that the inner core is spinning faster than the surface. [mas] It almost stopped around 2009. “Now it’s slowly moving in the opposite direction,” says geophysicist Xiaodong Song of Peking University in Beijing.

The world is turning upside down

Yang also explains that by observing and analyzing our planet’s inner core between the 1990s and 2020s, it is possible to notice a clear shift in recent years. Because the core’s spin is driven by the magnetic field of Earth’s outer core, the research could also help to understand how different layers of our planet interact with each other.

But not everyone agrees with Beijing researchers, for example, Australian National University geophysicist Hrvoje Tkalcic said the inner core is not capable of stopping completely. He suggests that the inner core is more in sync with the rest of the planet as it spins faster than it used to.

“It’s likely unrelated to life on the surface, but we don’t really know what’s going on. “It’s up to us to figure this out,” said University of Southern California geophysicist John Vidale.
