Graded on a Curve
Rob Skiba and Rick Hummer tested the curve of the earth with practical science observation. It was said that the skyline of Chicago seen from across lake Michigan was a mirage. It is supposedly impossible to see because of the curvature of the earth is too great at that distance. Rob and Rick put their money where their mouth was and went out to see for themselves.
Is the earth flat? If not, shouldn’t we be able to test it?
