That the Earth is round or that it is not the center of the universe is about as close to a "given" we can get to. Yet, despite my limited familiarity with Norwegian (which relies largely upon knowledge of Swedish, Danish, German, Old Norse, Icelandic, etc.), I can safely say that there exists no term for "not a proponent of round 'Earthism'" and that., while heliocentric remains a term in use, there exists no equivalent term for "the Earth doesn't move". That's because it's clearly idiotic and pointless to have a term that can identify one's position as not that of another, specific position. If you don't go around identifying yourself as an atheist, either you don't identify yourself as an atheist, or you do. If you do, this isn't a given or there would by definition be no reason to identify yourself as such (it would be "given").
