The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
NASA computer simulation using the model of Glatzmaier and Roberts. [38] The tubes represent magnetic field lines, blue when the field points towards the center and yellow when away. The rotation axis of the Earth is centered and vertical. The dense clusters of lines are within the Earth's core. [27]
Polar drift is a geological phenomenon caused by variations in the flow of molten iron in Earth's outer core, resulting in changes in the orientation of Earth's magnetic field, and hence the position of the magnetic north- and south poles. The North magnetic pole is approximately 965 kilometres (600 mi) from the geographic North Pole. The pole ...
Hugh Auchincloss Brown (23 December 1879 – 19 November 1975) was an electrical engineer who advanced a theory of catastrophic pole shift.Brown claimed that massive accumulation of ice at the poles caused recurring tipping of the axis in cycles of approximately 4000–7500 years.
Charles Hutchins Hapgood (May 17, 1904 – December 21, 1982) [1] was an American college professor and author who became one of the best known advocates of the pseudo-scientific claim of a rapid and recent pole shift with catastrophic results.
It descends, creating a cold, dry high-pressure area. At the polar surface level, the mass of air is driven away from the pole toward the 60th parallel, replacing the air that rose there, and the polar circulation cell is complete. As the air at the surface moves toward the equator, it deviates westwards, again as a result of the Coriolis ...
VIPER (Volatiles Investigating Polar Exploration Rover) is a lunar rover which was developed at the NASA Ames Research Center.Before the project was cancelled in 2024 the rover would have been tasked with prospecting for lunar resources in permanently shadowed areas of lunar south pole region, especially by mapping the distribution and concentration of water ice.
The book explores a version of pole shift hypothesis postulated by Professor Charles Hapgood in two volumes, plus the 1967 book Cataclysms of the Earth by Hugh Auchincloss Brown. When Brown published "Cataclysms", he was in his 90s, so he is represented in the novel by the character Herbert Allan Boardman (The "HAB" of the title) also in his 90s.
