Well, not exactly. Einstein actually preserved an objectively real universe, one which all observers could agree upon, notwithstanding the relativity of their motions and thus their perceptions of time. The Newtonian universe wouldn't have been proposed if it had been known that observers everywhere in the universe perceive the passage of time differently. Only relativity (a horribly named theory in my opinion) holds it all together.
Well, sure. But the issue in question is--is einstein's universe just a minor correction in the least significant figures to newtonian physics, as my deponent contends? Or is it a radically different universe?
