Can relativity be considered complete ? From Newtonian nonlocality to quantum nonlocality and beyond

Abstract

We review the long history of nonlocality in physics with special emphasis on the conceptual breakthroughs over the last few years. For the first time it is possible to study "nonlocality without signaling" {\it from the outside}, that is without all the quantum physics Hilbert space artillery. We emphasize that physics has always given a nonlocal description of Nature, except during a short 10 years gap. We note that the very concept of "nonlocality without signaling" is totally foreign to the spirit of relativity, the only strictly local theory.

12 pages, inspired by talks I gave in 2005 at the IOP conference on Einstein in Warwick, the QUPON conference in Vienna, the {\it Annus Mirabilis} Symposium in Zurich, le séminaire de l'Observatoire de Paris and the Ehrenfest Colloquium in Leiden
