But isn't that just conjecture? I mean sure it is feasibly (extremely low chance) of it happening but from reading this site, it seems you can just make stuff up because "it fits/works." Isn't science about first disproving nulls then giving hypotheses on what could be affecting it? Also I do not believe that gps would work without satellites. Wouldn't almost any military, communications, or gps company realize there are no satellites. Also if you believe there are satellites, why can't we use pictures of the freaking earth. I just feel that while feasibly possible, that doesn't mean it is true. And as of now, there are lots of problems with flat earth theory due to common phenomena. If you can create a theory that addresses all of them while staying consistent with what we observe, then maybe fe will be = to re. But you can never be certain which one is true (according to you).
Also, The ice walls would have to be about pretty high up to keep the atmosphere in. We would be able to see it. Also, Ice doesn't like the really low pressures of the end of the atmosphere (it boils). And a glass dome that magically fits over earth? I guess its plausible though highly unlikely. Surely even the staunchest Flat earther believes that round earth can be true.
