woops, looks like my memory blanked out.
Thanks for the update hehe. For a non scientist you you have a good nose to spot flaws. :-)
But who actually proved it again... Was it Pythagoras?
With all the water and he spinning motion the globe is more eliptical then round.
I have been looking into the flat earth theory like @tmave117 mentioned but that makes my mind go into overload when trying to figure out how a plane can go around the flatness, and how this would work with sattelites.
Still i found some interesting ideas about this.
And what if earth is a dodecahedron?
