Discovering the Hollow Earth

What is really under our feet?

The subsoil has always fascinated human beings with the idea of the existence of other worlds under the surface.
The ancients often saw it as a dark place, full of the souls of the deceased, the bowels of the earth were the scenario in the collective imagination of hell and the home of strange beings, fairies and gnomes: at one time the Eskimos were called Trolls by the Scandinavians because, according to legends, they were thought to come from inside the Earth. The Eskimos themselves claim to come from a distant and underground place and other populations admit the existence of an underground world, hidden and not easily accessible: we have all heard the stories regarding Eldorado, Agharta and Shamballah.
According to these legends, common to many peoples, the evolved empires of the past were annihilated in a single night by a great cataclysm. Some of the survivors would have descended inside the planet giving birth to a civilization hidden from our eyes, divided between two other great continents, Eldorado and Agharta, the first accessible from the South Pole, the second from the North Pole.

The genesis of the Hollow Earth Theory

The Earth has a radius of 6378 km but geologists do not know exactly what lies deeper than 4000 meters.
Although traditional science has shown that the interior of the Earth is made up of a series of layers, ridges and molten magma, surrounding a core composed mainly of iron and nickel, not all share this view. In the 17th century an alternative hypothesis was put forward, the so-called hollow earth theory.

The authorship of the above theory is attributed to Edmund Halley who in 1692, during some studies on terrestrial electromagnetism, recorded some anomalous results with the compass on the basis of which he hypothesized that the Earth could be a planet composed of a series of concentric "shells", rotating in different directions, all around a central core. This model would explain the recorded results, even in light of what was known about the gravitational pull of the sun and moon on Earth.
He speculated that between one shell and another there could be environments reached by light, perhaps inhabited by life forms.

Although this theory was the subject of harsh citics, others including J.T. Mayer and Leonhard Euler continued Halley's studies who resumed his initial idea by suggesting some changes: the shells were replaced by a huge cave, containing a small Sun whose presence would have allowed the existence of an environment that is not only habitable, but also luxuriant.

In 1818, American war veteran John Cleves Symmes Jr. published Circular No. 1 and became the most famous and influential proponent of the hollow earth theory: he argued that there were large holes in the Poles, which could allow access to the world hidden inside.


Symmes proposed an expedition to the North Pole where he was sure to find the so-called "Symmes Holes". He too thought that the Interior of the Earth contained life, but not only that: he claimed it was full of "vegetables and animals, if not men". He was never taken seriously and was reduced to writing a novel, Symzonia, in which he described the hypothetical journey of Captain Adam Seaborn to the center of the Earth. Here, Seaborn discovered the existence of a world very similar to the surface one and of a light-skinned population.

A few years later, healer Cyrus Teed proposed a similar but "reversed" idea, the Concave Earth Theory according to which the entire universe was contained in a huge shell: man therefore lived inside a hollow Earth, and the universe itself was the illusion generated by a strange solar phenomenon.
The surface of the Earth, according to this theory, would resemble the inside of a Dyson Sphere.


The Hollow earth theory

The beliefs associated with this theory are manifold and range from the idea that the Aurora Borealis is the emanation of the light of the Hollow Earth and that according to which the Nazis would have reached the Hollow Earth and made a pact with its inhabitants. Hitler himself would be hiding there.

In the opinion of many people, the Hollow Earth would be a kind of tropical paradise, probably home to an advanced race of humans, aliens or giants. Scenarios hold that these creatures are descendants of ancient races, such as the Lemurians or the Ten Tribes of Israel, guided across the opening of the North Pole by God himself. However, they are peaceful creatures, far more advanced than humans on the surface. God would have made sure that the internal Sun provides an ideal amount of heat to create the perfect climatic conditions for the life and development of animals and people of greater size and stature and physically stronger than those residing on the surface. In some cases the world within is associated with Agartha, a legendary city that was initially idealized within Tibetan Buddhism.

Proponents of the hollow earth theory believe there is a worldwide conspiracy to hide the existence of these "underground" races and also to hide Symmes' Holes. In more recent times they have also tried to organize an expedition to the North Pole, but the initiative would have failed following a series of vicissitudes attributed to an intervention by the international powers.

Many also talk about the cover-up of a secret report by Admiral Richard Byrd, who claimed to have been the first to reach both the North Pole and the South Pole by air, and which apparently included the story of the passage through the Holes and the encounter with one of the races of the Interior.

"As I came down the Highgate Hill I met the sun's bravado, And saw below me, fold on fold, Grey to pearl and pearl to gold, This London like a land of old, The land of Eldorado."
