I think that we can never prove that something is Right, we can just prove that something is Now Wrong for Now.
I think, you are still not exactly separating observations and experiments from interpretation. Experiments always give the same results regardless of who does them. A metre is a metre, a second is a second, if you repeat experiments using identical conditions. This is, what I mean with results of an experiment. How these results then fit into a theory is another thing.
Newton's laws are already a theory, an interpretation, not results of an experiment. Say, you want to do an experiment that can distinguish between the validity of Newton's laws and Relativity. So, you measure time and length and get some results. Up to a certain velocity (also a result) you cannot distinguish between both. So, the same results are consistent with two different theories, or realities, if you like.
