You can't prove the Earth is flat. Neither can you prove it is round. In fact, no self respecting scientist would ever claim to have 'proved' anything. All you can do in the real world (i.e. not the world of pure mathematics etc) is show that something is somewhere on the scale between possible and very very likely. But how is this important to a flat or round earth theory?
Well you could argue that what makes a good scientific theory (and Flat Earth and Round Earth both claim to be scientific) is one that is useful in some way, for example theories of voltage, current etc giving rise to modern electronics and its sister disciplines. The theory of gravity is useful because we can use it along with some classical mechanics to predict the behaviour of heavy objects in structural engineering and the forces experienced by aircraft. These theories are (relatively) simple, and give us accurate and useful predictions about what might happen in an as yet untested theoretical situation, like if we built a building with no supporting structure on one of the walls (gravity decrees: crashshhhhhh).
The point of this thread is just to ask, as a scientist whose round earth/flat earth alignment is irrelevant, which, if either, of the two proposed theories are of use to us? If we have two models that both explain current events, which is better in terms of fewest axiomatic assumptions and fewest unknown quantities? (Occam's Razor slices again!)
Btw sorry for the long longness but I have just invented an exciting new theory about particles I call conspiratons. They are invisible, immeasurable and have no mass, but they account for all unknown things in the universe due to their strange properties...but wait, how does it help that I know that?
