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 ...
Geomagnetic polarity during the last 5 million years (Pliocene and Quaternary, late Cenozoic Era). Dark areas denote periods where the polarity matches today's normal polarity; light areas denote periods where that polarity is reversed. A geomagnetic reversal is a change in a planet's dipole magnetic field such that the positions of magnetic ...
The north magnetic pole, also known as the magnetic north pole, is a point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down). There is only one location where this ...
Tamsin Hughes. . . ( m. 1941; div. 1955) . 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.
The south celestial pole currently lacks a bright star to mark its position, but over time precession also will cause bright stars to become South Stars. As the celestial poles shift, there is a corresponding gradual shift in the apparent orientation of the whole star field, as viewed from a particular position on Earth.
The Laschamp or Laschamps event [note 1] was a geomagnetic excursion (a short reversal of the Earth's magnetic field). It occurred between 42,200 and 41,500 years ago, during the end of the Last Glacial Period. It was discovered from geomagnetic anomalies found in the Laschamps and Olby lava flows near Clermont-Ferrand, France in the 1960s. [1][2]
The South Geomagnetic Pole is the point where the axis of this best-fitting tilted dipole intersects the Earth's surface in the southern hemisphere. As of 2020, it is located at 80°39′S107°19′E80.65°S 107.32°E, [ 7 ] whereas in 2005, it was calculated to be located at 79°44′S108°13′E79.74°S 108.22°E, near Vostok Station.
The 2012 phenomenon was discussed or referenced by several media outlets. Several TV documentaries, as well as some contemporary fictional references to the year 2012, referred to 21 December as the day of a cataclysmic event. The UFO conspiracy TV series The X-Files cited 22 December 2012 as the date for an alien colonization of the Earth, and ...
