- sliken 4y agoSure, it's under heavy debate. While the idea or the planet spinning at different speeds weird to think about, the physics do work out. After all not like the atmosphere spins at exactly the same speed as the planet. Why should the core of the planet in a pool of magma spin at exactly the same rate? The discussed difference is only 0.1 degrees per year, on the surface of the planet that's only 7 miles. So what's under the surface today might be 7 miles different in a year. The movement that deep is quite a bit less than 7 miles since the circumference at that depth is much less. Additionally it's not rock and dirt at that depth, but a liquid magma with an average speed of a foot a day is not too surprising. Humans think of these things as constant, but the length of the day and the distance of the moon are changing because tides are transferring rotational energy of the earth into the moon. Said forces aren't directly impacting the spin of the core, so it might well be catching up and oscillating around the speed of the earth's rotation every 35 days.
