FE theory states stars are localized light, in or around the “firmament” or “dome”. In order to replicate that theory, a planetarium would require the surface to be of the same shape to accurately represent the stars in there respected positions. If the earth was a sphere and the universe was ever expanding and not curved, a planetarium could be shown on a flat surface.
By your logic, should they be flat like everything else in the universe?
