This is long, but interesting so let me try to summarize.

In early 1900s, two lines measuring 4250 feet each were hung down a mine shaft on several occasions in order to calculate the radius of the earth. Scientists expected the bottom of the lines to be closer together than the top, but the opposite was found to be true. The bottom of the lines was 8.2 inches further apart than the top. Several theories were put forth to explain the reasoning behind this, but all failed to account for the large discrepancy from the expected results.

This was my favorite theory: One central tenet of Teed's philosophy held that the earth is a hollow rock shell, and we live and walk on the inside surface of this shell. The entire universe, which is mostly an illusion caused by gravic and levic rays and light, lies within this shell. This complicated view was called the cellular cosmogony, the earth-cell theory or the Koreshan cosmogony.

Hmmm. I wonder want's on the outside then... Seems to cause more problems than it solves, even for the simple-minded folk who believe this (and I have met at least one guy who believed this).

Don't forget, that first space flight came 50 years later...
