Re: OT: Earth\'s orbit changing?
If I remember right, the theory in question says that the sun's electromagnetic field initiated Earth's magnetic field. Once the dynamo effect kicked in, the Earth's field became self-sustaining. Eddies in the flow of magma are what cause the local maxima and minima, similar to the way weather is created in the atmosphere.
