By the way, the earth isnt a true sphere, its an Oblate Spheroid, and if we include water into the equation (Which is a BIG part of Earth), the moon pulls the water a little (tides),thus distorting the overall shape again!
Just thought I'd point that out, well, a mate mentioned it in the pub lastnight (He likes conversations like this, lol)
*Edit: oh, and he mentioned*
he thinks the worlds not flat too, just by looking at the GPS system, 20 odd satellite, all in medium orbit around the globe, all relaying information, and all with known positions in space... Basically, he suggests that if you plotted each coordinate of each satellite, and shoved the data in a 3D modelling program, say as a vertex, and joined them all up, you would in fact, end up with a blocky sphere shape.
