Led by a team from the University of Southern California (USC), the researchers behind the finding think this change in the core’s rotation could change the length of our days – albeit only by a few fractions of a second, so you won’t need to reset your watches just yet.
“When I first saw the seismograms that hinted at this change, I was stumped,” says Earth scientist John Vidale from USC. “But when we found two dozen more observations signaling the same pattern, the result was inescapable.
