Pole shift 2012

pole shift theory is a hypothesis that the axis of rotation of a planet has not always been at its present-day locations or that the axis will not persist there; in other words, that its physical poles had been or will be shifted. Pole shift theory is almost always discussed in the context of Earth, but other solar system bodies may have experienced axial reorientation during their existences.

Pole shift theories are not to be confused with plate tectonics, the well-accepted geological theory that the Earth's surface consists of solid plates which shift over a fluid asthenosphere; nor with continental drift, the corollary to plate tectonics which maintains that locations of the continents have moved slowly over the face of the earth,[1] resulting in the gradual emerging and breakup of continents and oceans over hundreds of millions of years.[2]

Pole shift theories are also not to be confused with Geomagnetic reversal, the periodic reversal of the earth's magnetic field (effectively switching the north and south poles). Geomagnetic reversal has more acceptance in the scientific community than pole shift theories.
