Ever been in a cave? Some caves are enormous. Yet the ceiling doesn't crash to the floor.
All over the world there are natural arches in the rocks. The rocks wedge themselves together in such a way, that a bridge is built at the top of the arch. These arches have lasted thousands of years.
The earth is almost 8,000 miles. thick Why couldn't there be an outer shell made up of arch structuring... a shell that was, say, 1,000 mile thick, and went all the way around the whole earth in every direction? The earth could be hollow, with the hollow part having a diameter of 6,000 miles.
Science and scientists misinterpret many things. They might be misinterpreting their seismic readings that suggest the earth is solid with a liquid core. If they knew the truth of a hollow earth, would they tell you? Think of the text books that would have to be changed! Scientists would become a laughing stock. Nobody would trust them for anything anymore. They would lose their station and pay in life. We can't have that, now, can we?!
