Hollow Earth Theories
The Three Major Theories Of Hollow Earth
The Hollow Earth Theory of one kind or another has actually been around for a very long time. While the very first ideas could today be considered rather whimsical and unsophisticated, the suggestion has gradually gained traction over time in some quarters. There have even been some hints from satellite photos which indicate that there may be more substance to the idea than most people would believe.
There have been three major hollow Earth models proposed: 1) The Concentric Spheres Hollow Earth, 2) the Polar Holes Hollow Earth Model and 3) The Inverted Hollow Earth Model

The Hollow Earth Theory #1:
The Concentric Spheres Hollow Earth Model
Likely the first hollow Earth theory to be promulgated was that by Edmund Halley in 1692. As one of the most respected scientists of his day, his conclusions were taken seriously by the world. After all, had he not discovered, with the crudest of instruments, the comets who regularly visit our planet? If he could do that, while peering into the vast universe, why would he not be able to discover amazing truths closer to home? His ideas were an attempt to rationalize how the Earth’s electromagnetic fields could fluctuate as widely as they did when tested. His conclusion was that there had to be at least four concentric shells inside the Earth, each with its very own magnetic field to account for the changes that occur.
​
The motion created by each shell compared to the others permitted distinct areas of the field to stray around the world. Halley felt the most logical explanation was that there had to be a series of shells within each other – that was his Hollow Earth Theory.
The Hollow Earth Theory #2:
The Polar Holes Hollow Earth Model
Perhaps the most widely recognized hollow Earth theory consists of significant polar openings approximately 3,000 kilometers in size that allow access to the inside of the Earth. Numerous hollow Earth investigators have searched with all manner of vehicles for these openings. However absolutely nothing has ever been discovered. Some claim that modern satellite technology has actually confirmed that such holes have been spotted, but are not as easy to locate as some would have us believe; there have been some ambiguous readings.
​
In the Polar Holes Hollow Earth Theory, the center of the planet has a main source of energy and light – its own internal sun – that supplies light and warmth to the world within.
The Hollow Earth Theory #3:
The Inverted Earth Hollow Earth Model
This theory may be not only the least well-known of the Hollow Earth theories, idea but perhaps the strangest of hollow Earth concepts. The model works on the principle that we are really living inside a hollow world today and the center of our world is much farther away.
​
All the other planets, the moon, satellites and the sun revolve around this main point. The Inverted Earth Hollow Earth Theory says that we have it all wrong and the way we see things is really inside out.
​
Sometimes suspension of disbelief requires too much effort.

Ancient Theories
The concept of a subterranean world inside the Earth’s shell has been a popular vision in legend, folklore and tales of ancients, told round campfires and passed on through the oral tradition for hundreds of generations.
​
Back then, the concept of subterranean worlds appeared feasible, and became linked with the concept of “places” such as the the underworld of Greek mythology, the Nordic Svartfaheimr, the Christian Hell, and the Jewish Sheol (about information describing internal Earth in Kabalistic literature, such as the Zohar and Hesed L’Avraham).
​
According to the ancient Greeks, there were caves which were entries leading deep into the earth, some of which were the caverns at Tainaron in Lakonia, at Trozien in Argolis, at Ephya in Thesprotia, at Herakleia in Pontos, and in Ermioni. In Thracian and Dacian folklore it is claimed that there are underground chambers inhabited by an revered god called Zalmoxis. In Mesopotamian religion we learn of a man who, after traveling through the blackness of an underground passage in a mountain called “Mashu,” entered an underground garden.
​
Celtic mythology has a legend of a cavern called “Cruachan,” additionally known as “Ireland’s gate to Hell,” a legendary and old cave from which, according to the tale, locals would sight weird beings emerge. There are likewise stories of medieval knights and saints who journeyed to a cave located in Station Island, County Donegal, in Ireland, where they made quests inside the planet to an area of purgatory. An Irish legend mentions tunnels in County Down, Northern Ireland, that lead to the subterranean Tuatha de Danaan, a special set of people who may have brought Druidism to Ireland, and then returned underground.
​
An old tale of the Angami Naga tribes of India reveals that their ancestors emerged in old times from a subterranean land inside the earth. There are myths from the Tai-no people that their ancestors emerged long ago from two caves in a the side of a mountain.
​
An ancient Mexican legend says that a mountain tunnel, located five miles south of Ojinaga, Mexico is possessed by devilish creatures that came from inside the mountain.
​
During the middle ages, a myth circulated that a portal to the hollow earth existed in mountains located between Eisenach and Gotha in Germany.
​
Likewise, an old Russian legend claimed the Samoyeds, an old Siberian tribe, went to live inside a city inside a mountain.
​
In North America, a Native American legend stated that the forefathers of the Mandans in arose from a subterranean land through a cavern at the northern edge of the Missouri River. The San Carlos Apache Indian Reservation in Arizona was also thought to hold a strange tribe which lived within the earth. The Iroquois, a fierce native tribe with a long history in Canada passed on stories of their ancient forefathers who had emerged from an underground world inside the earth. Hopi elders believed that an entrance in the Grand Canyon existed which could lead to the underworld.
​
South America also had native tribes who mentioned the inner earth in stories of yore. Brazilian Indians, who live along with the Parima River in Brazil, contended that their ancestors emerged in old times from the underground and that numerous ancestors were still to be found underground. Even the mighty Incas held that their forefathers came from underground caves, situated east of Cuzco, Peru.
17th Century
Edmond Halley in 1692 put forth the idea of Earth consisting of a hollow shell about 800 km (500 mi) thick, with two inner concentric shells and an innermost core, about the diameters of the planets Venus, Mars, and Mercury. Atmospheres separate these shells, and each shell has its own magnetic poles. The spheres rotate at different speeds. Halley proposed this scheme in order to explain anomalous compass readings. He envisaged the atmosphere inside as luminous (and possibly inhabited) and speculated that escaping gas caused the Aurora Borealis.
De Camp and Ley have claimed (in their Lands Beyond) that Leonhard Euler also proposed a hollow-Earth idea, getting rid of multiple shells and postulating an interior sun 1,000 km (620 mi) across to provide light to advanced inner-Earth civilization but they provide no references; indeed, Euler did not propose a hollow-Earth, but there is a slightly related thought experiment.[22]
​
They also postulated that Sir John Leslie had expanded on Euler’s idea, suggesting two central suns named Pluto and Proserpine (this was unrelated to the dwarf planet Pluto, which was discovered and named some time later). Leslie did propose a hollow Earth in his 1829 Elements of Natural Philosophy (pp. 449\endash 453), but does not mention interior suns.
Le Clerc Milfort in 1781 led a journey with hundreds of Creek Indians to a series of caverns near the Red River above the junction of the Mississippi river, according to Milfort the original Creek Indian ancestors are believed to have emerged out to the surface of the earth in ancient times from the caverns. Milfort also claimed the caverns they saw “could easily contain 15,000 \endash 20,000 families.”[23][24]
19th Century
In 1818, John Cleves Symmes, Jr. suggested that the Earth consisted of a hollow shell about 1,300 km (810 mi) thick, with openings about 2,300 km (1,400 mi) 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. United States president John Quincy Adams indicated he would approve of this but he left office before this could occur. The new President of the United States, Andrew Jackson, halted the attempt. It is possible this is the source of the (untrue) legend that Jackson believed in a Flat Earth, and was consequently the only United States president to do so.
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\endash 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 hypothesis, but failed to mention Symmes himself. Symmes’s son Americus then published The Symmes’ Theory of Concentric Spheres in 1878 to set the record straight.
20th Century
The Nazi era Thule Society reported much about Tibetan myths of openings into the Earth. There is even a theory that Hitler ordered a research journey for such an opening in Antarctica, based on a speech of Admiral Donitz in front of a German u-boat in 1944, when he claimed, “The German submarine fleet is proud of having built an invisible fortification for the Furhrer, anywhere in the world.” During the Nuremberg Trials, Donitz spoke of “an invisible fortification, in midst of the eternal ice.”
​
The spiritualist writer, Walburga, Lady Paget, in her publication, Colloquies, wrote about an unseen companion. It was 1907 and she was one of the earliest authors to discuss the hollow Earth concept. She declared that cities exist beneath a desert, which is where Atlanteans moved to. She promised that an entry to the subterranean kingdom will certainly be found in the 21st century.
​
William Fairfield Warren, in his book, Paradise Found: The Cradle of the Human Race at the North Pole believed that humanity come from on a continent in the Arctic called Hyperborea. This affected some very early hollow planet thinkers.
​
According to Marshall Gardner, who wrote A Journey to the Earth’s Interior (in 1913), both the Eskimo and Mongolian peoples had come from the inside of the hollow Earth through an entrance at the North pole.
He placed an interior sun inside the Earth and developed a working scale design of the hollow Earth which he patented in the US. At about the same time, Vladimir Obruchev wrote a story called \i Plutonia\i0 , in which the hollow Earth had internal sunlight and was occupied by primitive beings. An opening in the Arctic connected the underground world.
​
Ferdynand Ossendowski was an explorer who wrote a manual in 1922 titled Beasts, Men and Gods. Ossendowski claimed he was told by some mysterious being about a subterranean kingdom that existed inside the planet.
​
In his book, Anything Can Happen, published in 1940, George Papashvily spoke of the discovery in the Caucasus mountains of a cave filled with human skeletons “with heads as big as bushel containers.” He also mentioned an old passage leading to the center of the earth. He claimed that one chap entered the tunnel and never returned.
​
Many have proposed that “Ascended Masters” of esoteric knowledge inhabit subterranean caverns or a hollow Earth. Antarctica, the North Pole, Tibet, Peru, and Mount Shasta in California, USA, have all been mentioned as places of entry to a subterranean realm known to Buddhists as Agartha. Some have even promulgated the theory that UFOs have their base in these locations.
​
Author Lobsang Rampa in his book, The Cave of the Ancients said an underground chamber system exists beneath the Himalayas of Tibet, loaded with ancient machinery, manuscripts and treasure.
​
Michael Grumley a cryptozoologist, has actually connected Bigfoot and various other hominoid cryptids to ancient underground tunnel systems.
​
Douglas Baker said in one of his books that he experienced an astral trip to the inner planet where he observed a subterranean civilization. Other occult writers such as Guy Ballard and Alice Bailey have also written about “out-of-body” experiences and claim they met mysterious beings inside of the earth.
According to Peter Kolosimo, who wrote about ancient astronauts, a robot was seen entering an underground tunnel below an abbey in Mongolia. He further avers a light was seen from underground in Azerbaijan; he thought it was a UFO.
​
A manual supposedly by Dr. Raymond Bernard showed up in 1964, called The Hollow Earth. It talks about UFOs coming from inside the earth. Bernard argued that the residents of Atlantis took refuge in the Earth’s interior before the city was completely demolished.
​
A post by Martin Gardner revealed that Dr. Walter Siegmeister utilized the pseudonym, “Bernard,” but not until the posting of Walter Kafton-Minkel’s Subterranean Worlds: 100,000 years of Dragons, Dwarves, the Dead, Lost Races & UFOs from Inside the Earth, in 1989, did the full tale of Bernard/Siegmeister name-switching become publicly known.
​
The magazine, Amazing Stories, highlighted many tales about the paranormal and UFOs between 1945 and 1949. Who knows how many or how few had any basis in fact? Ray Palmer was the fearless editor who employed Richard Sharpe Shaver, writer of the tales that purported to be real.
​
Shaver claimed that a superior pre-historic race had created a honeycomb of caves in the Earth, and that their degenerate descendents, known as “Dero,” live there still, making use of the fantastic devices deserted by the old races to torment those of us living on the surface. He wrote that tormented voices were a product of their agony down under. Thousands of readers wrote to verify that they, too, had actually heard the fiendish voices from inside the Earth.
​
David Hatcher Childress then authored Lost Continents and the Hollow Earth (1998) in which he republished Palmer’s stories and argued for the hollow Earth concept, based on underground passages said to be found beneath South America and central Asia.
​
Hollow Earth proponents have pointed to a variety of different locations where the entrances can be found, which lead deep inside planet Earth.
​
Incredible tales (taken as gospel within some groups, but also confirmed by others who claim to have inside knowledge, like Ritter Von X – See Dan Weiss’s Special Report on his exclusive interview) have likewise maintained that Adolf Hitler and several of his followers were obsessed with finding the Hollow Earth entrance during and after the War. Some even claim that not only was there an entry in Antarctica, but that Hitler and some of his henchmen made it there. We remain a little more than agnostic on this issue.
​
In 2011, Horatio Valens and Paul Veneti offered a two-hour “Lazeria Map Collection” video clip of centuries-old charts of the Arctic area and the North Pole, suggesting that there is a 100-mile wide gulch in the physical North Pole, into which north-flowing streams drain into a hollow Earth. The charts were collected by Harry Hubbard.
​
Some individuals have suggested that humans live on the outside surface of a hollow world; this is often called a “convex” hollow-Earth hypothesis. Others have actually claimed that our world itself depends on the interior of a hollow world, calling this a “concave” hollow-Earth hypothesis. The area of the Earth, according to such a view, might look like the interior shell of a sphere.
​
Cyrus Teed, a doctor from upstate New York, proposed such a concave hollow Earth in 1869, calling his system “Cellular Cosmogony.” Teed founded a team called the Koreshan Unity based upon this idea, which he called Koreshanity. He fancied himself as a new Christ, a peculiar breed of megalomania. The cult following moved from New York state to Florida, where their estate prospered until the death of the last true believer, after which, the property was deeded to the state as tourist destination for those interested in seeing an historical site, at Estero, Florida. Teed’s fans declared that he had to have experimentally validated the concavity of the Earth’s curve, by surveying the Florida shoreline, having used “rectilineator” machinery.​
​
German authors have shown a particular fascination with the hollow Earth. Writers, including Peter Bender, Johannes Lang, Karl Neupert, and Fritz Braun have each published research papers and books supporting the hollow Earth theory, or Hohlweltlehre.​
​
There has even been talk about Adolf Hitler having been convinced of concave hollow-Earth ideas, that he sent out an expedition in an unsuccessful attempt to spy on the British fleet by aiming infrared cameras up at the sky.
​
An Egyptian mathematician, Mostafa Abdelkader, apparently created several academic research papers providing a comprehensive mapping of the concave Earth model.
​
In one chapter of On the Wild Side (1992), Martin Gardner talks about the hollow Earth model mentioned by Abdelkader. He theorized that a drill would lengthen as it traveled away from the cavern and eventually pass over the “factor at infinity” equivalent to the center of the Earth in the widely approved scientific understanding of the planets and the universe.
21st Century
In 2011, Horatio Valens and Paul Veneti presented a two-hour “Lazeria Map Collection” video on centuries-old maps of the Arctic region and the North Pole, making a case for a 100-mile wide canyon in the center of the physical North Pole, into which north-flowing rivers drain into a hollow Earth. The maps were collected by Harry Hubbard.
