We all know that the shortest path between two points on a plane is a straight line. On the surface of a sphere, however, there are no straight lines. The shortest path between two points on the surface of a sphere is given by the arc of the great circle passing through the two points.

Doesn't matter what scale the sphere or ball is, you NEVER use 180 degree, level, flat, horizontal lines to shape a fucking ball.

If you want to take up black science mans position that Earth is an "oblate spheroid" and a little "pear shaped" then where is that shown in any of the supposed photographs of Earth taken from kiked governmental agencies?

Hey, I like that argument. Must go play with images now.
