If the earth is flat, how thick or thin is it?
Can we dig through to the other side?
What is on the other side of the flat earth?
Does the atmosphere wrap around the edge of the flat earth to the other side?
Does anyone live on the other side of the flat earth? If so, why haven't we made radio contact with them?
Why is the earth flat? What are the natural forces that could possibly have produced such a shape?
Why aren't there any other flat planets, or for that matter flat asteroids, flat moons, flat comets, flat stars, etc?
Gravity must necessarily be false for the earth to be flat, considering the earth's mass. Gravity requires an oblate spheroidal earth. Anything as massive as the earth would naturally collapse into a ball under it's own gravity. This is why, in outer space, everything more than a few hundred kilometers in diameter is spherical in shape. So how could the earth be any different? What do you have to replace gravity with...a flat earth that is perpetually falling up?
