Is Einstein's Special Relativity True?

For newton, the only thing that counts is the distance between two bits of mass. And so f that's not changing, then the gravity shouldn't change at all, right? Even for a perfect sphere, what it does is it drags the space around it a little bit. Einstein says that if you a really big, massive object and you spin it, then you drag space itself along with the object. But einstein's special relativity is not the isin's theory of general relativity.
