Sorry for the title I didn't really know how to title this. Could you prove the Earth's shape by planting instruments that give you their location on a 3D plain across America. If these instruments showed up on perhaps a screen that shows their relation to each other by distance and angles wouldn't this prove if there was a noticeable curve or flat plain that they rest on? Perhaps proving the shape of this Planet, or Island. Whatever it could be called? It would not be affected by light bending. Effected or affected, whatever. I'm sure there is a way to prove the shape by a measure of electrical instruments that give at least a general vision of the shape, size and a geographic location of where everything is positioned. This could easily give Flat Earth a rough map if planted in various countries to show you their positioning and distance in relation to each other. Ideas for possible experiments that could be done? I see allot of people throwing theories around but no one putting these theories into action or testing. I'm actually pretty impatient considering there is an organization dedicated to a possible Flat Earth, but for some odd reason there's no projects, no donations going toward anything that could put this theory into motion. Just a bunch of people sitting around saying "you can't prove that the world isn't flat and you can't use things people have proven that go against our theory." These same people can't even agree upon a basic outline of the countries in position to each other. This isn't an attack and I'm not ranting. All I am asking is simple questions. All that has ever been asked is simple questions. Still with no answers, just possible theories without any logical or relevant testing.
