Uh, Earth’s Inner Core Just Stopped Spinning
Popular Mechanics ^ | 2/15/23

Posted on 02/15/2023 5:21:53 AM PST by EBH

A new study published in Nature Geoscience by geophysicists Yi Yang and Xiadong Song of Peking University in Beijing explored the nature of movement of Earth’s inner core, largely made up of iron and molten liquids. They found the inner core’s movement recently reduced enough they consider it “paused,” all part of what “seems to be associated with a gradual turning back of the inner core as a part of an approximately seven-decade oscillation.”

The last turning point was in the early 1970s.

The new study further tracked seismic waves through the core to see how they played out on the other side of Earth. “This globally consistent pattern suggests that inner-core rotation has recently paused,” the study says.

With the spin changing throughout the decades, the authors believe there’s an interplay between the spinning of the core and Earth’s mantle, and not just a spinning core for spinning’s sake.

“This multidecadal periodicity coincides with changes in several other geophysical observations especially the length of day and magnetic field,” the authors write. “These observations provide evidence for dynamic interactions between the Earth's layers, from the deepest interior to the surface, potentially due to gravitational coupling, and the exchange of angular momentum from the core and mantle to the surface.”

Or the whole solar system has core’s that switch every 70 years or so. Interesting coincidence.

The Polar Vortex Is Literally Breaking Apart…

In this video we are talking about how the Polar Vortex is about to fall apart and potentially cause major changes as we go into March..

“... in the 70s i could jump higher than i can today.”

That has to do with the fact that gravity is increasing, which may or may not be related to the spin of the earth’s core. I know that gravity is increasing because of the following points:

1. I can’t lift things I used to.
2. I can’t jump as high as I used to.
3. When I fall down, I hit harder and it hurts more.
4. When I step on the scale, it reads higher than it used to. (This last is measurable, scientific proof.)

You just know that sooner or later Democrats are going to say this was caused by Global Warming.

The earth is racist? I always suspected that. In fact, the unspoken accusation is that God himself is racist. If brother Al could extort a few bucks, it would be worth it to him.

I’ve noticed that, too! I thought it was just me…

I remember the Sylmar quake in 1971, woke up to bed moving across the room. The earth actually moved like a wave, felt like being in a boat.

Doorknobs are lower than when I was a kid. How about for you?

This would easily pass for scientific research at any university today. If you could somehow get some discrimination against anyone who isn’t straight and white in there you could probably get $millions in grant money.

I had an opportunity some years back to visit the house where I grew up. The whole place had shrunk quite a bit. No idea how that could happen.

Oh, I know how to do scientific research, all right. First draw the curve, then plot the points, and finally tabulate the data.

A rotation swap and a polarity swap are two different things. A polarity swap causes a weak and erratic magnetic field lasting hundreds of years or more. The last known polarity swap was about 780 million years ago. The magnetic field protects us from solar winds (radiation). Nobody knows for sure how dangerous the conditions would be. Bottom line however, if there was no magnetic field, there would be no life as we know it. No magnetic field = dead planet.

In my younger years I did a lot of traveling to the wild places of the world. Stayed away from the touristy destinations and got out into their wildness.

Getting back home everything in the house seemed ...small and disproportionate. That perception faded in a few days, but it was weird at the time.

I spent one summer teaching riding at a horse ranch for kids (16 years old at the time). At the end of summer when I returned home, I had the same effect.

It is just weird. Maybe it is because it is mundane?
