Scientists have been debating the movement of the inner core for decades, with some studies suggesting it rotates faster than the surface and others arguing the opposite. This new research provides clear evidence that the inner core started slowing down around 2010 and is currently lagging behind the Earth's surface.
The recent study's results were described as 'inescapable' by researcher John Vidale, who noted the surprise at the inner core's slowdown after multiple observations confirmed the pattern. The study stands out as the most convincing resolution among recent arguments about the inner core's movement.
