Earth Core Slowing Down

Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery.

This inner core has intrigued researchers since its discovery by Danish seismologist Inge Lehmann in 1936, and how it moves — its rotation speed and direction — has been at the center of a decades-long debate. A growing body of evidence suggests the core’s spin has changed dramatically in recent years, but scientists have remained divided over what exactly is happening — and what it means.

Part of the trouble is that Earth’s deep interior is impossible to observe or sample directly. Seismologists have gleaned information about the inner core’s motion by examining how waves from large earthquakes that ping this area behave. Variations between waves of similar strengths that passed through the core at different times enabled scientists to measure changes in the inner core’s position and calculate its spin.

USC study confirms the rotation of Earth’s inner core has slowed

Study shows clear evidence that core speed began to decrease around 2010.

USC scientists have proven that the Earth’s inner core is backtracking — slowing down — in relation to the planet’s surface, as shown in new research published Wednesday in Nature.

Movement of the inner core has been debated by the scientific community for two decades, with some research indicating that the inner core rotates faster than the planet’s surface. The new USC study provides unambiguous evidence that the inner core began to decrease its speed around 2010, moving slower than the Earth’s surface.

Changes in core spin — though they can be tracked and measured — are all but imperceptible to people on Earth's surface, Vidale said. When the core spins more slowly, the mantle speeds up. This shift makes Earth rotate faster, and the length of a day shortens.Jul 5, 2024

Got $50B and some unobtainium?

Thanks Obama.

Also, Brandon.

That is totally made up. Unobtainium is fake, unlike Helium, Iron, and Upsidaisium.

Shouldn't this be cross-posted to the Is Gaia conscious? thread?

What is it that made Gaia decide to act now?

Core

Earth’s core is the very hot, very dense center of our planet.

The core is found about 2,900 kilometers (1,802 miles) below Earth's surface, and has a radius of about 3,485 kilometers (2,165 miles). Planet Earth is older than the core.Jun 11, 202400

Not very far beneath us.

So...is there a chain of consequences that flow from this? Earthquakes, etc.?
If so, can't we simply issue hula hoops to every person on earth, and on a given day, have everyone from the Aleuts to the Zimbabweans hula hoop in a preset spin direction, until surface and core sync up?
If Trump was in office, he could simply create a giant faucet on the Columbia River and count on the swirling of the currents to reset these things. But hula hoops is my own concept of a plan.

Perhaps the core is Gaia's fidget spinner.

We know precious little about it. Earthquakes no. The length of a day may change by a few milliseconds, causing some of our digital technology to gradually step out of sync with our celestial position, and there may be some as yet poorly understood changes to the earth's magnetic field. Nothing catastrophic. If there were substantial effects during such phases, we would have geological evidence of it from previous periods of slowing.

This is a bit like trying to slow down your car by asking one of your mitochondria to run the other way.

I mean, we don't know what the periodicity of the slowing is, do we? And if we do... Does it coincide with field orientation changes?

It could very well be that the technology we use to find "north" may itself change. Not that we can stop it, mind, but we should probably figure out and file a plan for that as a species.

Literally as far beneath us as it possibly could be. Nothing could be further beneath us.

Worse...

Jon Amiel might make another movie about it.

Oi!

Hey... anyone in here know how we could completely squander the acting talents of Eckhart, Swank, Tucci, Woodard... and to a lesser extent Greenwood, Lindo, and Karyo?

Damn straight. That guy ever try to get Aleuts to cooperate with Zimbabweans on anything?

So, if I'm hearing you all correctly, no one's on board with my hula hoop event?
