I haven't seen any good explanations for the coriolis effect, if the earth is a flat and motionless disk...and since it must be compensated for by hunters, snipers and anyone traveling from point A to B, it most certainly exists.
You can take a trip due west, then due south, then due east and you will end up at your starting point, forming a triangle pattern of travel path. If earth is flat, you would end up south of your starting point with a C shaped travel path.
One thing, however, is that the recent WMAP experiments that have created visual representations of "cosmic background radiation" show that the earth is centered within the known universe, and that the radiation emanates outward from earth. The idea that earth is insignificant or that our universe has no particular structure aside from random instances of celestial bodies is proven wrong. The CMB experiments were performed over a decade with 3 successive launches, each one delivering the same results.
I am open to new ideas in the pursuit of truth, therefore, I am willing to consider that the physical geometry of our Earth is not as is commonly explained...although I approach the matter with no desire to support an ideological perspective.
