In fact, his objection had absolutely nothing to do with relativity. His objection was essentially that how could two particles that no longer interact with each other still manage to influence each other's state. He tries to conclude from this that the quantum mechanical description is essentially incomplete. For anyone with an undergrad QM background, both the original EPR paper and Bohr's reply should be fairly accessible, and form an interesting reading. They appeared in Physical Review in 1935 (+-1) within 1 issue of each other. - mayank. -------
