Let me put it this way: the evidence we have that the laws of physics are Lorentz Invariant have been tested in at least as many ways as the fact that the Earth is round, and over an enormous range of space and time.

Now, if you want to argue that the Earth is not round, you'll be mistaken, but you can (I guess) be satisfied with the answer that you will get no argument about that from me.
