A fascinating theory of a hollow instead of a solid sphere as the shape of our earth has been under active consideration and research for over two centuries. There are several Websites on the Internet supporting this theory with a large mass of solid information of various kinds.
The Hollow Earth Theory
The Hollow Earth Theory states that the earth is not a solid sphere with a central, hot magma which is yet to cool, but a hollow sphere that has a thick crust of landmass only around the circumference, with openings at the north and south poles. There is an ‘inner sun’ at the centre of the earth. The ring of land crust is supposed to be between 600 and 800 miles in thickness and the polar openings between 100 and 1400 miles in diameter. This leaves a space of over 7000 miles at the centre, which is hollow.
In direct contravention to the proportion of land and water mass being of the ratio 1:4 on the surface, the inner crust has this proportion in the ration 4:1, that is, four-fifths of land and only one-fifth of water. The reason for this reversal is that the floors of the surface oceans are actually landmass on the inner side!
A unique feature of this theory is that it logically confronts the currently accepted solid earth theory, with facts that orthodox science has overlooked. The adherents of this theory point to its origins in the religious myths throughout the world, the science fiction works of the 17th and 18th centuries, and the ‘anomalies’ found during the Arctic expeditions undertaken over the last two centuries.
Some of these adherents subscribe to the thinking that a whole civilization of prosperous, peaceful and technologically more advanced humans live in a world of highly evolved vegetable and animal life sustained by the ‘inner sun’ of the hollow earth, on the vast continents of land mass that form the inner side of the surface world we are living.
There are also people who think that the stories of dark entities such as the werevolves, vampires, ghosts and other ghastly creatures that are said to occupy the caverns under the earth might have some element of truth in them.
