Proof that the world is not flat

In summary, Zee explains that by using the distances between four points on a flat piece of paper, one can deduce that the world is not flat. This is because the distances between four points cannot be accurately represented on a flat surface, indicating that the Earth's surface is not a Euclidean plane. This is further supported by calculations that show the disagreement between the total area of the triangles formed and the area of the quadrilateral formed, suggesting that the cities discussed are not coplanar.

This thread seems to be taking on a life of its own, or am I imagining that?. Its interesting to see serious people discussing such an off the wall fringe notion. I sense a little entertainment value here. :doh:

Well, it would be pretty sad if we couldn't prove the Earth was flat, wouldn't it? My fave is applying general relativity to the flat Earth hypothesis.

Oops. I'd also like to know who that South African flat Earth prime minister was. That was pre-Internet.

I think the main point was a slam dunk right from the go, but I have enjoyed this thread immensely. Thus the bonus entertainment value. :smile:
