Question 22. Would a ring of cold material in the upper mantle sufficient to produce the rotational instability you talked about in your 2008 ICC presentation, if present from the earth’s creation, not cause rotational instability immediately from the beginning of history instead of waiting some 1650 years between Creation and the Flood?
Response: Actually, it can be shown that, if there are no external torques or internal perturbations, the earth will spin indefinitely about its initial spin axis, even if an orthogonal axis has a larger moment of inertia. Indeed, in my numerical solution of Euler’s equations, starting with this sort of initial state, I must intentionally introduce a perturbation to trigger the rotationally unstable behavior. If I do not, the system continues happily forever in its initial state.
