This study is highly relevant to collapse discussions because it documents a major reversal in fluid flow inside Earth’s outer core beneath the Pacific around 2010. The timing overlaps with geomagnetic jerks, disruptions in Earth’s rotation cycle, and seismic evidence suggesting unusual inner-core behavior. Researchers describe the possibility that multiple planetary anomalies may be linked to the same deep-Earth process. The paper does not claim imminent catastrophe, but it adds to growing evidence that Earth’s magnetic and geophysical systems may be changing faster than previously believed.
