We're talking about 50,000 times that of plate tectonic motion.

What we see right now is a snapshot of a long time process between the magnetic field and the inner core. I do expect to see this rate change with time.

Extraordinary claims require extraordinary proof. We believe we have that proof.

Differential rotation is a fundamental dynamic process that goes to the heart of the origin of our planet and how it has evolved. There is still much to learn about the inner Earth.

Essentially, the waves that traveled through the area outside the inner core?the crust, the mantle, the outer core?are all the same. Only when they travel through the inner core are they different.
