Flat Earth Question

Does FE completely contradict the theory of gravity or is gravity a possible occurance on perhaps other celestial bodies (in which Earth would be an exception)?

I'm not one for double-posting / bumping, but I think the flood knocked my topic down a bit too far.

Any thoughts or comments?

Well, it would have to contradict the traditional gravity theory in which gravity is an attraction between masses, otherwise the earth would have to have gravity...

But I suppose we could still have other celestial bodies with the property of "gravity", but simply identifying the phenomenon woul get us nowhere closer to what causes it.
