Key point: Earth's core rotates at almost exactly the same rate as the rest of the planet. Did in the past, still does so now. It rotates at the same speed to within 0.001%!
But even the research paper is confusing on that point: #RealityCheck

What's notable here is that Earth's inner core rotates *almost* the same as the surface, but not *exactly* the same. It may rotate a tiny bit faster or slower -- and that's not apocalyptic, but it sure is interesting. #Earth #Core
