You cannot possibly gain new knowledge about physics by doing moral philosophy. At best, you have shown that any version of utilitarianism which adheres to your assumptions must specify a privileged reference frame in order to be coherent, but this does not imply that this reference frame is the true one in any physical sense.

This seems untrue. If you have high credence in the two premisses:
If X were a correct physical theory, then Y.
Not Y.
then that should decrease your credence in X. It doesn’t matter whether Y is a proposition about the behaviour of gases or about moral philosophy (although the implication is likely to be weaker in the latter case).
