Abstract

We present the possibility of a relativistic formulation of the Einstein-Podolsky-Rosen argument. We pay particular attention to the need for a reformulation of the so-called reality criterion. We introduce such a reformulation for the reality criterion due to Ghirardi and Grassi and show how it applies to the nonrelativistic EPR argument. We elaborate on Ghiradi and Grassi’s proof and explain why it cannot be circumvented. Finally, we review and summarise our own views. This is a continuation of the paper by myself and Patrick La Riviere whose defects are exposed in the present work.
