It is a belief system plus a constraint. The constraint is that all
conclusions from the belief system are empirically testable and that the
conclusions are corroberated by observation (experiment). Science
differs from religion in that it does not have a built in set of excuses
for its failures to coincide with what is seen.

There is no doubt a set of unverified assumptions at the base of
physics. Among these is the assumption that physical laws are the same
everywhere and in every direction. Physics based in New York is the same
physics as is based in Paris or Moscow or on the star Sirius.
