This is both true and misleading. If you restrict objectivity to tautologies (which calculations are), the vast gulf between "the moon goes around the Earth" and "Justin Bieber is the BEST!" goes unexplained.

But the moon does go around the Earth. No alternative choice or interpretation can yield a different answer. You might trip yourself up on language, or if you're eighteen months old you might not be too solid on what "around" means. But any ordinary skill with language places the phrase "The moon goes around the Earth" so solidly into the realm of the well-understood that there doesn't appear to be any room left for reasonable disagreement (flat earthers notwithstanding--if objectivity is going to mean anything other than "everyone agrees", then we may conclude that they're wrong).
