The theory of special relativity is based on those two postulates.
General relativety further assumes that the laws of physics are the same
in all frames of reference, not just inertial ones.
No scientific theory is ever proved correct in the strong sense. It can
only be proved in the weak sense that it fits all observations to date.
There is a lot of evidence that the postulate of the constancy of c is
true. Everyone "knew" this before Einstein's theory of relativity
(that's why he used it). He stripped away all assumptions (like
absolute space and time) and just stuck with the one that was causing so
much trouble and the mach principle that motion has no meaning in itself
can only be said to be relative to something else. He completely
overturned conventional wisdom about the nature of the universe, a man
after your own heart surely.

Mike.
