Earth’s core has slowed so much it’s moving backward, scientists confirm. Here’s what it could mean

 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. One promising model proposed in 2023 described an inner core that in the past had spun faster than Earth itself, but was now spinning slower. For a while, the scientists reported, the core’s rotation matched Earth’s spin. Then it slowed even more, until the core was moving backward relative to the fluid layers around it. 

But not all are convinced that the matter is settled, and how a slowdown of the inner core might affect our planet is still an open question — though some experts say Earth’s magnetic field could come into play.

Picked up a 1” cube of nickel from Luciteria; hard stuff.

Better call Aaron Eckart and Hillary Swank to get the core back on track.

In not so many words, they don’t know.

Whatever happened to the conservation of angular momentum? And if the core stopped spinning at one point, wouldn't it mean that no magnetic field would be generated around the planet, meaning all life wiped out by solar radiation?

An article I read said that the magnetic field has decreased by 9% in the last 200 years. Article didn't give any explanation as to why.
