Yes! Nature is the authority. Our scientific method allows us to pose any question and it allows us to gain understanding when said questions are testable and repeatable. Notably: we never get to know anything, sadly But, we do understand monkey see, monkey do style: do A get B Observing nature is key, but not the only key. Observation coupled with mathematics allows us to process observation analytically, and all of that allows us to... Guess and test! Richard Feynman taught this at Cornell, and it remains one of the best explanations of the scientific method around because it is clear, funny and short, to the point: https://m.youtube.com/watch?v=EYPapE-3FRw https://m.youtube.com/watch?v=EYPapE-3FRw And just another thing to add here, and that is science is not a belief system, nor does it require belief due to the method requiring we question everything, including the method! Notably, Feynman talks about things being likely or unlikely as a root driver for our guesses, which again depend on observation, that stumbling into that which can enlighten, math needed to predict, and experiment to test. Theory is not proof either. It is simply the most predictive understanding we have! Old theory still works as well as it ever did, and that build down to how predictive it is. Is a theory proven right? Nope, we can only say we have yet to prove it wrong. Example: Einstein Theory of General Relativity has been very difficult to prove wrong and it has been very predictive even when we have not expected it to be! Is Einstein right? Who knows? What we can say is no other theory is as predictive. And that will all stand, right up to the point where a guess from someone ends up testing better and predicts all that Einsteins does along with something new.
