Studies of the two scientists in China have found that the global core may have change

(Beijing French Xindian) According to a latest research report, the core of the earth has stopped rotating in the same direction as the external circle layer, and may even rotate in the opposite direction.

Song Xiaodong, a professor at the School of Earth and Space Science, Peking University, and Yang Yi, a special associate researcher, on Monday (January 23) on the latest research results released on Nature Geoscience, which reveals the core of the earth's core for nearly 70 years.Changes in differential rotation mode.

They told AFP that about 5,000 kilometers under the surface, the core of the earth, known as the "planet in the planet", floating in the metal nucleus floating in the liquid, so it can rotate independently.

The core of the earth is a hot iron ball structure with the size of Pluto.They found that the rotation of the Earth's kernel "almost stopped around 2009 and then turned to the opposite direction."

By analyzing the natural earthquake repeatedly occurred in the past 60 years, Song Xiaodong and Yang Yi discovered that the rotation of the earth's kernel was close to stopping and began to slowly reverse. "We believe that the earth's core will be relative to the surface of the earth and carry out the surface of the earth.Rotate back and forth, like Qiu Qianyi. "

They added that a back -and -forth cycle is about 70 years, which means that about every 35 years will change the direction.The last direction change was in the early 1970s, predicted that the next time it would occur in the mid -2040s.So far, there are almost no signs that the activity of the earth's kernel will have a significant impact on residents on the surface of the earth.

Song Xiaodong and Yang Yi believe that there is a physical relationship between all the earth floors."We hope that our research can inspire other researchers to regard the entire earth as a comprehensive power system, and to establish and test different models in this way."

How to rotate the earth's core has always been a problem that scientists have been arguing.Some scholars have proposed that the Earth's kernel changes direction every six years; some theories have pointed out that the core of the earth is rotated to a large extent between 2001 and 2013, and then the rotation stops.
