even an amateur can spot that, dumb round-earth believing ass
-sigh-
if the earth was round, the core would be in only one spot, dead-center in the earth. this would mean everybody would be attracted to one spot on the earth; the north pole or the south pole.
a representation would be an actual planet called Haumea. it is slightly flattened in shape, so that would technically mean the extended ridges would be like mountains. if the earth was completely flat, more than 90% of it would technically be an extremely steep cliff. not to mention the fact that the water would all pour into an ocean at the center.
also if there was an asteroid coming near us, we'd be forgeted twice up the ass and thrice down the throat.
