Simple Proof of the Globe: Distances Between 4 Cities
As discussed previously in Flat Earth Challenges , checking distance and area measurements is a fairly simple way to show it is impossible to map our Earth to a flat plane. Just pick 4 cities that are all fairly distant from one another (8000 km or more is perfect). The distances don't even have to be all that accurate, as we will show in our example. If you pick 4 cities that are closer to each other then you need more accurate distances. I don't want to have to care that much about having super accurate distances, I want something that is glaringly obvious. For my example I've used Sydney, Johannesburg, Buenos Aires, and London -- which I've also used before to show how utterly ridiculous the Gleason map is... But that's just one Flat Earth map. Let's destroy all Flat maps in one go... The Method What I did is pick the cities with the three longest routes and placed those first three cities that distance apart on a flat plane (Sydney, London, Buenos Aires
