This article is about the hypothesis of pole shift in its historical context. The shift the future of work is already here pdf a description of the modern scientific understanding, see true polar wander.
For magnetic poles, see Geomagnetic reversal. The cataclysmic pole shift hypothesis suggests that there have been geologically rapid shifts in the relative positions of the modern-day geographic locations of the poles and the axis of rotation of the Earth, creating calamities such as floods and tectonic events. There is evidence of precession and changes in axial tilt, but this change is on much longer time-scales and does not involve relative motion of the spin axis with respect to the planet.
However, in what is known as true polar wander, the solid Earth can rotate with respect to a fixed spin axis. Earth’s pole were found during this period.
Between approximately 790 and 810 million years ago, when the supercontinent Rodinia existed, two geologically rapid phases of true polar wander may have occurred. The geographic poles are defined by the points on the surface of the Earth that are intersected by the axis of rotation. Earth, resulting in the gradual emerging and breakup of continents and oceans over hundreds of millions of years. In popular literature, many conjectures have been suggested involving very rapid polar shift.
A slow shift in the poles would display the most minor alterations and no destruction. A more dramatic view assumes more rapid changes, with dramatic alterations of geography and localized areas of destruction due to earthquakes and tsunamis.
An early mention of a shifting of the Earth’s axis can be found in an 1872 article entitled “Chronologie historique des Mexicains” by Charles Étienne Brasseur de Bourbourg, a specialist in Mesoamerican codices who interpreted ancient Mexican myths as evidence for four periods of global cataclysms that had begun around 10,500 BCE. In 1948, Hugh Auchincloss Brown, an electrical engineer, advanced a hypothesis of catastrophic pole shift.
Brown also argued that accumulation of ice at the poles caused recurring tipping of the axis, identifying cycles of approximately seven millennia. In his controversial 1950 work Worlds in Collision, Immanuel Velikovsky postulated that the planet Venus emerged from Jupiter as a comet.
