Hollow Earth is a belief that the planet Earth has a hollow interior and, possibly, a habitable inner surface. The hypothesis of a Hollow Earth has long been contradicted by overwhelming evidence as well as by the modern understanding of planet formation, and the scientific community now dismisses the notion as pseudoscience.

The deepest hole that's been drilled to date is the SG-3 borehole which is 7.62 miles (40,230 ft or 12,262 metres)[1] deep, part of the Kola Superdeep Borehole project, and thus visual knowledge of the Earth's structure extends that far.

[edit] Hollow Earth claims

[edit] 19th century

In 1818, John Cleves Symmes, Jr. suggested that the Earth consisted of a hollow shell about 800 miles (1,300 km) thick, with openings about 1400 miles (2,300 km) across at both poles with 4 inner shells each open at the poles. Symmes became the most famous of the early Hollow Earth proponents. He proposed making an expedition to the North Pole hole, thanks to efforts of one of his followers, James McBride, but the new President of the United States, Andrew Jackson, halted the attempt.

Jeremiah Reynolds also delivered lectures on the "Hollow Earth" and argued for an expedition. Reynolds went on an expedition to Antarctica himself but missed joining the Great U.S. Exploring Expedition of 1838 - 1842, even though that venture was a result of his agitation.

Though Symmes himself never wrote a book about his ideas, several authors published works discussing his ideas. McBride wrote Symmes' Theory of Concentric Spheres in 1826. It appears that Reynolds has an article that appeared as a separate booklet in 1827: Remarks of Symmes' Theory Which Appeared in the American Quarterly Review. In 1868, a professor W.F. Lyons published The Hollow Globe which put forth a Symmes-like Hollow Earth theory, but didn't mention Symmes. Symmes's son Americus then published The Symmes' Theory of Concentric Spheres to set the record straight.

[edit] Recent history

An early twentieth-century proponent of a hollow Earth, William Reed, wrote Phantom of the Poles in 1906. He propounded the idea of a hollow Earth, but without interior shells or inner sun.

Marshall Gardner wrote A Journey to the Earth's Interior in 1913 and an expanded edition in 1920. He placed an interior sun in the hollow Earth. He even built a working model of the hollow Earth and patented it (#1096102). Gardner made no mention of Reed, but did take Symmes to task for his ideas. In the same time Vladimir Obruchev wrote a fiction novel Plutonia, where the hollow Earth's interior possessed one inner (central) sun and was inhabited by prehistoric species. The interior was connected with the surface by a hole in the Arctic.

Other writers have proposed that "ascended masters" of esoteric wisdom inhabit subterranean caverns or a hollow Earth. Antarctica, the North Pole, Tibet, Peru, and Mount Shasta in California, USA, have all had their advocates as the locations of entrances to a subterranean realm referred to as Agarttha, with some even advancing the theory that UFOs have their homeland in these places.

A book allegedly by a "Dr.Raymond Bernard" which appeared in 1969, The Hollow Earth, exemplifies this idea. The book rehashes Reed and Gardner's ideas and ignores Symmes. Bernard also adds his own ideas: UFOs come from the interior, the Ring Nebula proves the existence of hollow worlds, etc. An article by Martin Gardner revealed that Dr.Walter Siegmeister used the pseudonym `Bernard', but not until the publishing of Walter Kafton-Minkel's Subterranean Worlds: 100,000 years of dragons, dwarfs, the dead, lost races & UFOs from inside the Earth, in 1989, did the full story of Bernard/Siegmeister become well known.

The pages of the science fiction pulp magazine Amazing Stories promoted one such idea from 1945 to 1949 as "the Shaver Mystery". The magazine's editor, Ray Palmer, ran a series of stories by Richard Sharpe Shaver supposedly claimed as factual, though presented in the context of fiction. Shaver claimed that a superior pre-historic race had built a honeycomb of caves in the Earth, and that their degenerate descendants, known as "Dero", live there still, using the fantastic machines abandoned by the ancient races to torment those of us living on the surface. As one characteristic of this torment, Shaver described "voices" that purportedly came from no explainable source. Thousands of readers wrote to affirm that they, too, had heard the fiendish voices from inside the Earth.

Fantastic stories (supposedly believed as factual within fringe circles) have also circulated that Adolf Hitler and some of his followers escaped to hollow lands within the Earth after World War II via an entrance in Antarctica. (See also Hitler's supposed adherence to concave hollow-Earth ideas, below.)

Some writers have proposed building megastructures that have some similarities to a hollow Earth -- see Dyson sphere, Globus Cassus.

[edit] Concave hollow Earths

Example of a concave hollow Earth. Humans live on the interior; with the universe in the center.

Instead of saying that humans live on the outside surface of a hollow planet, sometimes called a "convex" hollow-Earth theory, some have claimed that our universe itself lies in the interior of a hollow world, calling this a "concave" hollow-Earth theory. The surface of the Earth, according to such a view, might resemble the interior shell of a Dyson sphere. Generally, scientists have taken neither type of speculation seriously.

Cyrus Teed, an eccentric doctor from upstate New York, proposed such a concave hollow Earth in 1869, calling his scheme "Cellular Cosmogony". Teed founded a cult called the Koreshan Unity based on this notion, which he called Koreshanity. The main colony survives as a preserved Florida state historic site, at Estero, but all of Teed's followers have now died. Teed's followers claimed to have experimentally verified the concavity of the Earth's curvature, through surveys of the Florida coastline making use of "rectilineator" equipment.

Several twentieth-century German writers, including Peter Bender, Johannes Lang, Karl Neupert, and Fritz Braun, published works advocating the hollow Earth theory, or Hohlweltlehre. Stories have even been circulated, although apparently without historical documentation, that Hitler was influenced by concave hollow-Earth ideas and sent an expedition in an unsuccessful attempt to spy on the British fleet by aiming cameras up into the sky (Wagner, 1999).[2]

The Egyptian mathematician Mostafa Abdelkader authored several scholarly papers working out a detailed mapping of the concave Earth model. See M. Abdelkader, "A Geocosmos: Mapping Outer Space Into a Hollow Earth," 6 Speculations in Science & Technology 81-89 (1983). Abstracts of two of Abdelkader's papers also appeared in Notices of the American Mathematical Society, (Oct. 1981 and Feb. 1982).

In one chapter of his book On the Wild Side (1992), Martin Gardner discusses the hollow Earth model articulated by Abdelkader. According to Gardner, this theory posits that light rays travel in circular paths, and slow as they approach the center of the spherical star-filled cavern. No energy can reach the center of the cavern, which corresponds to no point a finite distance away from Earth in the widely accepted scientific cosmology. A drill, Gardner says, would lengthen as it traveled away from the cavern and eventually pass through the "point at infinity" corresponding to the center of the Earth in the widely accepted scientific cosmology. Supposedly no experiment can distinguish between the two cosmologies. Martin Gardner notes that "most mathematicians believe that an inside-out universe, with properly adjusted physical laws, is empirically irrefutable". Gardner rejects the concave hollow Earth theory on the basis of Occam's Razor.

In a trivial sense, one can always define a coordinate transformation such that the interior of the Earth becomes "exterior" and the exterior becomes "interior". (For example, in spherical coordinates, let radius r go to R²/r where R is the Earth's radius.) Such transformations would require corresponding changes to the forms of physical laws; the consensus suggests that such theories tend towards sophistry[citation needed].

[edit] Newtonian Gravity and a Hollow Earth

Someone on the inside of a hollow Earth would not experience an outward pull and could not stand on the inner surface; rather, the theory of gravity implies that a person on the inside would be nearly weightless. This was first shown by Newton, whose shell theorem mathematically predicts a gravitational force of zero everywhere inside a spherically symmetric hollow shell of matter, regardless of the shell's thickness. A tiny gravitational force would arise from the fact that the Earth does not have a perfectly symmetrical spherical shape, and also from forces due to masses such as the Moon which do not form part of the spherical shell. The centrifugal force from the Earth's rotation would pull a person (on the inner surface) outwards, but even at the equator this is only 1/300 of ordinary Earth gravity.

The mass of the planet also indicates that the hollow Earth theory is unfeasible. Should the Earth be largely hollow, its mass would be much lower and thus its gravity on the outer surface would be much lower than it currently is.

[edit] Myths and hints

The oldest claims of the hollow earth are Tibetian myths. Those myths report of 3 openings into the earth: 2 near the poles and 1 in the Himalayas. The Thule society, which was closely known by Adolf Hitler, reported much about those myths. There is even the theory that Hitler ordered a research journey for such an opening in the Antarctica. This theory is based on a speech of Admiral Dönitz in front of the German submarine in 1944. During that speech, Dönitz claims, "The German submarine fleet is proud of having built an invincible fortification for the Führer, anywhere in the world." During the Nuremberg Trials, Dönitz spoke of "an invincible fortification, in midst of the eternal ice." These are the only serious hints of the theory of the hollow earth.
