The rotation of Earth's inner core really has slowed down, a new study has confirmed, opening up questions about what's happening in the center of the planet and how we might be affected.

Earth's inner core rotation slowing down; deceleration of core confirmed: study

Earth's inner core&nbsp;has always had a pace of its own. Surprisingly, scientists have known about the unusual behaviour since the mid-1990s. However, a recent study revealed that Earth's inner core has stopped spinning and might change its original direction of motion. A study published in Nature Geoscience stated that the internal core rotation of our planet recently paused after geoscientists analysed the motion pattern. In 2009, the movement stopped suddenly and started moving in the opposite direction. Earth's inner core moves in relative motion with the speed of Earth like a swing, and one cycle of the swing is about seven decades, geoscientists told AFP. Previously, it switched paths in the early 1970s. According to the prediction by researchers from China's Peking University, the successive motion would be in the 2040s.&nbsp;

Our planet earth consists of three layers, crust, core and mantle. The Earth's core again divides into two, the inner and outer. Let's look deeper into the Earth's inner core to understand what's happening.

<h2>What is Earth's inner core?</h2>

In 1936, scientists discovered it while analysing the waves that travel through the planet during an earthquake. About 7,000 kilometres wide, it is made up of a shell of liquid iron wrapping a solid centre of the iron.&nbsp;

A study in 1996 revealed that the travelling speed of seismic waves through the Earth's inner core demonstrated a periodic variation over the last three decades. The rotation rate grew faster by 1 degree per year than the mantle and crust.&nbsp;

<h2>What will happen due to directional change in Earth's inner core?</h2>

According to the researchers, the core's rotation directly connects to a day's length, Earth's rotation, and Earth's mantle and crust. They have also cited evidence of gravitational coupling that led to dynamic interactions between all three layers of Earth. However, no evidence shows that the directional change in Earth's inner core has affected the routine lives of people.&nbsp;

Earth's inner core might have stopped and changed direction: Check out what happens now!

Scientists have recreated the intense pressure conditions of Earth's outer core in a laboratory.

The study, conducted by researchers at the US Department of Energy's SLAC National Accelerator Laboratory, has been published in Physical Review Letters.

Earth's inner core is under pressure about 360 million times higher than we experience in our everyday lives and temperatures approximately as hot as the Sun's surface.

According to the study's co-author Arianna Gleason, a scientist in the High-Energy-Density Science (HEDS) Division at SLAC, ''We didn't quite make inner core conditions.''

''But we achieved the conditions of the outer core of the planet, which is really remarkable.''

Earth’s magnetic field has been a life preserver, protecting against relentless solar winds, streams of charged particles rushing from the Sun, that otherwise could strip away the planet’s atmosphere and water.

"As we continue to push it, the iron doesn't know what to do with this extra stress," says Gleason.&nbsp;

"And it needs to relieve that stress, so it tries to find the most efficient mechanism to do that."

The coping mechanism iron uses to deal with that extra stress is called "twinning."

“Twinning allows iron to be incredibly strong,&nbsp;stronger than we first thought, before it starts to flow plastically on much longer time scales,” Gleason said.

Some asteroids in our solar system are massive iron objects that scientists suspect are the remnants of planetary cores after catastrophic impacts.

The researchers recreated deep-Earth conditions to see how iron copes with extreme stress.&nbsp;
