Hollow Earth Claims

Hollow Earth claims The earth we walk on is a hollow shell about 500 miles thick, with two inner shells and an innermost core. These shells are separated by atmospheres. Halley speculated that the inner spheres might be inhabited, and that light might be produced in a number of ways: the atmosphere might be luminous, or the inner sides of the spheres might emit light, or there might be small suns within the earth

The earth's hollow interior contained at its centre a small glowing core which served as a miniature sun for the inner world's hypothetical inhabitants. The inside surface is a beautiful world, in a more highly developed condition than the outside, and is accessible by a hole in the open polar sea'. The earth's inner concave surface is said to be habitable.
