Nothing to take away from your point, but the harsh fact about much of physics especially the modern kind is built on 'Models'. Most of it still remains true in that Model, even if a new Model shows totally different set of truths.

Albert Einstein himself said this about Entropy:

A theory is the more impressive the greater the simplicity of its premises, the more different kinds of things it relates, and the more extended its area of applicability. Therefore the deep impression that classical thermodynamics made upon me. It is the only physical theory of universal content which I am convinced will never be overthrown, within the framework of applicability of its basic concepts.
