The speed of the earth decreased

Faith is small

Our Earth’s inner core is one of the most mysterious things on our planet, and research into it often yields surprising results. Experts have recently revealed in a study that the inner core of the Earth has slowed down and the surface may start rotating in the opposite direction of the Earth. The researchers say that this is not a precursor to any natural signal, but it could affect the speed of the Earth’s rotation.

This deceleration may cause a slight difference in the Earth’s day and night hours and may also cause a change in the Earth’s gravity, but more research is needed to say anything definitive about this. According to Peking University-based expert Song Xiaodong in China, there is clear evidence that the core of the Earth was rotating faster than the surface, but by 2009, this process had stopped. According to a study, the inner core of the Earth is a sphere made of iron and nickel, with a radius of 1,221 km. This inner part of the earth is very hot.

Its temperature is 5,400 degrees Celsius which is almost equal to 5,700 degrees Celsius of the Sun. Surrounding this core is a thick layer of liquid metal called the outer core. Scientists have been trying for centuries to figure out how this inner core of the Earth rotates. The center of the Earth is defined as a planet within a planet.

Because it floats in a thick layer of liquid metals, it can circulate freely. The core of the Earth is difficult to study completely, as it is more than 5,000 kilometers below the Earth’s surface. What little we know about it comes from measuring small differences in the waves produced by earthquakes and nuclear explosions. The authors of the new study, Song Xiaodong and Yang Yi, analyzed the vibrations generated at the Earth’s core by analyzing various earthquakes over the past six decades.

According to experts, our theory not only argues that the Earth’s inner core swings from side to side like a swing, but that this happens in seven-decade cycles and changes direction every 35 years. According to their research findings, the last time its direction changed was in the early 1970s and the next change will occur in the mid-2040s. The rotation roughly corresponds to changes in day length, the researchers say, which are small changes in the exact time it takes for the Earth to rotate on its axis.

Experts have not yet found much evidence that changes in the Earth’s core are affecting the Earth’s surface, although researchers believe there are connections between all Earth’s layers. Scientists Yang and Song say they hope their findings will encourage researchers to build empirical models that view the Earth as an integrated dynamic system, but other experts are cautious about the new research. have been and cite other theories to warn of the many ongoing mysteries of the Earth’s core.

University of Southern California seismologist John Waddell did a study last year, which showed that the Earth’s core rotates very quickly and changes its direction of rotation every six years. His research was based on changes in seismic waves caused by two nuclear explosions in the 1970s.

Australian National University geophysicist Harvoji Kalcek said in a study that Earth’s core rotation cycles are between 20 and 30 years instead of 70. Because of the difference in these studies, John Waddell predicts more amazing secrets about our planet’s mysterious heart (core).
