Did you know that in every mile there should be 8 inches of curvature but those 8 inches of curvature has never been found experiments have been made trying to find a curvature such as a Bedford experiment. This was an experiment made in England to prove that the earth was flat. And no sign of curvature could ever been found.
It turns out that those 88 inches are multiplied by the square of the amount of miles so that means that into miles of curvature you would have in curvature the ammount of 2 to the 2nd power multiplied by 8. equaling 32 inches of curvature in just 2 miles.
