Quote:

Consider if you will Newtonian vs. Relativistic physics... each is inviolate in their respective realms (low v: newton; high v: relativity) but irrelevant in the other realm (newton doesn't apply at v~c and relativity doesn't apply at V<<c)



This is not true. Classical physics is indeed less accurate the higher the v, but relativity is always more accurate than classical physics no matter what v you've got.
