This is notes on flat-earth research. Whatever shape earth you walk on, its an interesting question to me why you think its that shape. To me, some of the reasons that people cite as evidence the earth is round are not particularly compelling on their own (even if there might be other evidence which is harder to explain, like lunar eclipses, which in a flat-earth model, would require positing the existence of another object, besides the sun the earth and the moon, which obstructs the moon during lunar eclipses, but is somehow only visible then).
