For the first time, researchers began talking about an unknown underground people in 1946. This happened after the writer, journalist and scientist Richard Shaver told readers of the American paranormal magazine Amazing Stories about his contact with aliens living underground.
According to Shaver, he lived for several weeks in the underworld of mutants, similar to the demons described in ancient legends and tales of Earthlings.
By the way, almost every nation has similar myths telling about the race of ancient creatures that inhabited planet Earth millions of years before a human foot set foot on it. Infinitely wise, talented and culturally advanced, they do not want to have anything to do with people.
One could attribute this “contact” to the writer’s wild imagination, if not for hundreds of responses from readers who claimed that they too had visited underground cities, communicated with their inhabitants and seen various miracles of technology, not only providing the Earth’s underground inhabitants with a comfortable existence in its depths, but also giving the opportunity to… control the consciousness of earthlings!
This extraordinary story, curiously, had a great impact on scientists and gave a new impetus to the study of the paranormal.
However, the fact that the Earth is an empty sphere was claimed in their writings by the 17th century English astronomer Edmund Halley, by the writers Jules Berne in his novel Journey to the Center of the Earth, Edgar Poe in The Narrative of Arthur Gordon Pym, and some others.
Moreover, in the XVIII-XIX centuries in the United States of America, the possibility of equipping a special scientific expedition was even considered, which would prove that our planet is a hollow sphere and it is easy to penetrate into its depths through holes in the earth’s crust.
But over time, staying underground is not so easy.
The deepest hole by far is one on Russia’s Kola Peninsula, near Murmansk, known as the “Kola well.” It was drilled for research purposes from 1970 onwards.
After five years, the Kola well reached 7 km (about 23,000 ft). Work continued until the project was abandoned in 1989 because the drill bit got stuck in the rock just over 12 km (about 40,000 ft or 8 miles) deep. That is the current record for the deepest depth reached by humans.
Therefore, the Earth’s shell is much larger than scientists can discover.
Scientists of the Third Reich were also very interested in the mysterious underground world. For example, in 1942, with the support of Goering and Himmler, an expedition, which included the most advanced minds of National Socialist Germany, went in search of an underground civilization in an atmosphere of great secrecy.
The “home” of the highly developed people of antiquity was to be found on the island of Rugen, located in the Baltic Sea. The expedition had other goals as well. German scientists seriously hoped that if they could place fundamentally new radar devices underground, they would come close to their goal of world domination.
In 1963, two American miners, David Fellin and Henry Thorne, while digging a tunnel, saw a huge door behind which marble steps led down.
The story takes us back to the events of August 13, 1963, in Sheppton, located in the anthracite coal belt of Schuylkill County in eastern Pennsylvania, where the famous Sheppton Mine disaster and rescue occurred. Three men were trapped about 330 feet underground after a mine shaft collapsed.
About two weeks later, on Tuesday, August 27, two of the miners, Henry Throne and David Fellin, were brought safely to the surface after rescue crews successfully drilled a 17 1/2-inch shaft and then a 28-inch shaft into their chamber, while the third miner, Lou Bova, trapped in another part of the mine, sadly died.
The story of Throne and Fellin’s survival and rescue was enough to captivate the world’s attention, but it was what they claimed to have seen and heard while entombed that fascinated the public, statements that both men swore to their authenticity, separately and publicly, emphatic statements that they took to their graves, although others believed that they had simultaneously witnessed the same hallucinations.

David Fellin’s ‘statement’ was printed in the Philadelphia Inquirer on August 29, 1963, where he commented: “Now they’re trying to tell me that these things were hallucinations, that we imagined it all. We didn’t. Our minds weren’t playing tricks on us. I’ve always been a hard-nosed, practical coal miner. My mind was clear down there in the mine. It’s still clear.”
Fellin went on to comment, how some of the things he and Throne saw, they could not explain in words, while on the other hand, he stated that, “On the fourth or fifth day, we saw this door, although we had no light from above or from our helmets. The door was covered in a bright blue light. It was very bright, better than sunlight. Two ordinary-looking men, not miners, opened the door.
We could see beautiful marble steps on the other side. We saw them for a while and then we didn’t see them anymore… We saw many other things like that that you couldn’t explain. But I won’t talk about them because I’m sorry about all of this.
Other miners in England, digging an underground tunnel, heard sounds of mechanisms working coming from below. When the mass of stone was broken through, a staircase leading to an underground shaft was also discovered.
The sounds of the machines working intensified. Scared to death, the workers fled and, returning to this place after some time, they no longer found the entrance to the underground well or the stairs.
In the 1970s, interesting photos were obtained from an American satellite, which were then circulated in many Western scientific journals: in the place where the North Pole should be, the satellite discovered a dark spot of the correct shape, similar to a huge hole. It would be possible to attribute these photos to equipment failures, if it were not for the exactly the same photos taken a few years later.
Also interesting are the testimonies of anthropologist James Macken, who examined a cave in Idaho, which is notorious among the indigenous population. Macken and his companions, after several hundred meters of careful movement along a wide stone corridor, suddenly heard screams and groans, and soon terrible finds in the form of human skeletons appeared before them. Unfortunately, the exploration of the cave, which in these parts was considered the entrance to the underworld, had to be interrupted: the smell of sulfur was simply unbearable.
If we turn to the opinion of scientists, geologists do not share the theory of the Earth’s omnipresent cavity, although they do not deny the possible presence of huge hollow spaces in its depths.
It is unlikely that people live there, because inside our planet there is not only a rather high temperature, but also very little oxygen, but it is full of other gases that are incompatible with human life. All this has led restless researchers to create a new hypothesis: perhaps the underground civilization has an extraterrestrial origin?
And why not? Perhaps alien beings, tired of the constant wars and conflicts of humanity, have moved underground, from where they still observe our development… And it is from under the earth, and not from other galaxies, that they appear from time to time. They spend time in the sky on flying saucers, come into contact with people and conduct their cruel experiments on them.
But here a legitimate question arises: if our Earth is still hollow inside, then why hasn’t the entrance to the underworld been discovered yet? The group of scientists from the United States came closest to the possible truth, which suggested the existence of underground cities… in the fourth dimension.

And only when the Earth’s electromagnetic field changes from time to time do tunnel entrances open on its surface, allowing you to see the underground cities and their inhabitants. At other times this is not possible.
And if we really lean towards the hypothesis that some kind of intelligent being lives in the bowels of our planet, many mysterious phenomena would find their explanation.
