Quite frankly, I believe anyone that posts this is completely daft. There are some things that can be proven of both flat earth and round earth theorists. However, in the study of PHYSICS there isn't a single thing that anyone can say to prove the earth is flat. The aforementioned time zones. Other sites claiming gravity is a figment of the imagination (so told it's completely inertia, whereby the apple theory with be invalid [though you would have to calculate it's potential energy in which the apple is stationary prior to falling versus inertial energy where the apple accelerates upon disconnection {call me crazy but inertia measures current velocity and not future velocity, right?}]) At any rate, if one can disprove the learning of physics (to Hawkings) I'll proudly change my opinion.
