Extraordinary claims require extraordinary evidence

I believe that the extraordinary should be pursued. But extraordinary claims require extraordinary evidence.

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.

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.
