'STUDDY' says Earth's core is reversing

well send some of you geniuses down there to check on it wouldja?
Of course, it must be noted this is more or less the plot of the 2003 disaster film The Core, but there’s no need to worry about averting an impending apocalypse by nuking the center of Earth. While the core’s rotation influences Earth’s surface environment, scientists think this periodic spin switch is a normal part of its behavior that does not pose risks for life on our planet.
Earth’s inner core is a solid metal ball that is 75 percent the size of the Moon. It can spin at different speeds and directions compared to our planet because it is nestled within a liquid outer core, but scientists are not sure exactly how fast it spins or whether its speed varies over time.
Located some 3,000 miles beneath our feet, the core experiences such intense pressures that it is likely as hot as the surface of the Sun. Because it is so remote and difficult to study, the inner core remains one of the least understood environments on our planet, though it’s clear that it plays a role in many processes that make our world habitable to life, such as the generation of Earth’s protective magnetic field, which blocks harmful radiation from reaching the surface.
Now, Yi Yang and Xiaodong Song, a pair of researchers at Peking University’s SinoProbe Lab at School of Earth and Space Sciences, have captured “surprising observations that indicate the inner core has nearly ceased its rotation in the recent decade and may be experiencing a turning-back in a multidecadal oscillation, with another turning point in the early 1970s,” according to a study published on Monday in Nature Geoscience.

“There are two major forces acting on the inner core,” Yang and Song said in an email to Motherboard. “One is the electromagnetic force. The Earth’s magnetic field is generated by fluid motion in the outer core. The magnetic field acting on the metallic inner core is expected to drive the inner core to rotate by electromagnetic coupling. The other is gravity force. The mantle and inner core are both highly heterogeneous, so the gravity between their structures tends to drag the inner core to the position of gravitational equilibrium, so called gravitational coupling.”
“If the two forces are not balanced out, the inner core will accelerate or decelerate,” they added. “Both the magnetic field and the Earth’s rotation have a strong periodicity of 60-70 years. We believe that the proposed 70-year oscillation of the inner core is driven by the electromagnetic and gravitational forces.”
Song has spent decades trying to unravel the mysteries of the inner core by studying seismic waves that pass through this distant region. He was part of the team that first reported evidence of the inner core’s rotation in 1996 by measuring slight time (or “temporal”) changes in these waves, which are generated by earthquakes.
However, the origin of the temporal changes has been a matter of debate within the geoscience community ever since, as some scientists think the wave patterns arise from phenomena at the boundary between the outer and inner core.

That's cool. I never knew about the core not being stationary. I have no clue why it moves and as long as it doesn't trigger anything harmful to me I don't care.

You mean if I dig a deep hole, I won't pop up in Chiner?

Just gotta keep panicking the sheeple...
I suppose banning cars and raising taxes will solve things...

and banning gas stoves. I hear they're thinking of banning air.

They sure tried to ban living...with their slow-acting Slab-Jab....and all the **MANDATES** to take that God-damned poison...
