Who's familiar with the Hollow Earth concept?
This concept of the Hollow Earth is coming from an ancient obsolete theory that asumed that the earth's core and earth mantle didnt exist, and that the earth is hollow. Also this theory also explained that this hollow space could possibly be habitable.
In ancient times there were many stories about underground empires, and societies living beneath the earthcore. One of these stories is about the Greek Hades, the Norwegian Svartalfheim and Hell.
Many have heard the theories that the Earth is hollow and inhabited by a highly advanced civilization and race of beings – many also believe that UFO’s are not from outer space but in fact are crafts manned by strange beings from our hollow Earth.. all is possible?
The idea of a hollow earth or underground empires also inspired many authors to make movies out of it. Examples:
Jules Verne in his book ''To the center of the Earth'' this booked has been filmed several times.
Indiana Jones and The Hollow Earth
Also the 1952 film The Mole People uses the theory.
