i'm a huge believer of the hollow earth theory.
The British astronomer Edmund Halley, of comet fame, proposed that the earth might consist of several concentric spheres placed inside one another in the manner of a Chinese box puzzle. The two inner shells had diameters comparable to Mars and Venus, while the solid inner core was as big as the planet Mercury. More startling was Halley's proposal that each of these inner spheres might support life. They were supposed to be bathed in perpetual light created by a luminous atmosphere. When there was an unusually bright display of aurora borealis, Halley postulated that it might have been caused by glowing gas escaping from the earth' s interior into our atmosphere.
