I accept that a round earth is not hollow, what goes down one hole comes up somewhere else.
Thus far, by the logic demonstrated here the earth is in fact not a 2 dimensional disc but is a multi layered 3 dimensional cylinder, oh, supported on the backs of 4 elephants who in turn stand on the back of a giant turtle. Just imagine what that would look like if viewed from space. Sideways on it would appear square or rectangular, in fact the only angle it would look like a perfect disc is if viewed from directly above. (underneath would just provide a view of the turtles arse) But as we have established we cannot view it from above because it is travelling upwards so fast that we would be smashed to death. Sorry, your logic remains flawed.
Fucking amazing regardless!
