A lot of respectable scientists and writers believed that Earth is hollow inside
Rumors about underground towns appeared for the first time in 1946. The person to launch the rumors was Richard Shaver – writer, journalist and scientist. His incredible story about contacts with aliens living under the ground was published in Amazing Stories Magazine. Shaver said that he had spent several weeks living under the ground with demon-looking aliens, whose descriptions can be found in ancient legends and fairytales. Almost every nation has a tale of an ancient race, who settled in planet Earth long before humans appeared on it. Those underground creatures are described as inconceivably talented, brilliant and culturally educated – they do not want to have anything in common with humans.
One could refer to the story from the American writer as a fruit of his vivid imagination. However, hundreds of readers responded to the publication. They wrote that they had visited underground cities, talked to their residents and saw unimaginable technical inventions, which guaranteed a comfortable existence in the very depth of the planet. Furthermore, the technologies of underground aliens give them an opportunity to control the minds of humans.
The unbelievable story exerted an immense influence on scientists and gave an incentive to the study of paranormal activities.
English astronomer of the 17th century, Edmund Halley, writers Jules Verne, Edgar Allan Poe and some others wrote in their works that planet Earth is a hollow sphere. American authorities were preparing a special scientific mission in 18-19 centuries to explore the Earth's hollow depth.
The scientists of the Third Reich were very interested in the mysterious underground world too. A special top secret expedition was organized in 1942. German scientists also hoped to install new radar systems under the ground and draw closer to global reign. Unfortunately, the outcome of the intrigue is not known, but the hypothesis of the underground civilization developed further on during the second half of the 20th century.
In 1963, two American coal miners, David Fellin and Henry Throne, found a large door in a tunnel, behind which they discovered a marble stairway. In England, miners can hear the sounds of mechanical devices under the ground, as they dig a tunnel. An English miner said that they had also found a stairway to an underground well. The sound of machines became more distinct, and the workers fled in fear. When they returned to the tunnel, there were no stairs and no entrance to the well.
An American satellite took very interesting photographs at the end of the 1970s. The photographs were published in many Western scientific magazines: the pictures depicted a dark, regularly shaped spot on the North Pole. The photographs were not defective: similar pictures depicting the same dark spot on the pole were taken several years later.
Anthropologist James McKenna explored an ill-famed cave in the State of Idaho. McKenna and other members of the expedition could hear screams and moans, as they were moving hundreds meters deep into the cave. The researchers found human skeletons soon, but they had to stop their quest: the smell of brimstone was unbearable.
Geologists do not share the theory of the Earth's huge cavity, although they do not exclude a possibility of numerous large hollow spaces in planet's depths. Human life is hardly possible in those cavities: the temperature is too high and there is very little oxygen there. Some researchers believe that the underground civilization might be of an extraterrestrial origin. Aliens were probably tired of people's eternal wars and atrocities, and moved under the ground, from where they comfortably observed the development of the mankind. What if UFOs appear in the sky from under the ground, not from other galaxies? However, if planet Earth is hollow inside, someone should have found the gateway to the underground world long ago. A group of American scientists believes that underground cities exist on Earth in the fourth dimension. When the Earth's electromagnetic field changes from time to time, entrances to the tunnels open, and accidental “visitors” may see the underground cities and their inhabitants.
One of the theories says that many mysterious constructions, like the English Stonehendge for example, were built to designate entrances to underground cities. If there is a reasonable race living under the ground, it would be an explanation to a lot of inexplicable phenomena.
