Can Relativity be Considered Complete? From Newtonian Nonlocality to Quantum Nonlocality and Beyond

We review the long history of nonlocality in physics with special emphasis on the conceptual breakthroughs over the last few years. (This was written at the end of Einstein’s year 2005, after Jurg Frohlich invited me to talk at the Annus Mirabilis Symposium he organized et the ETH Zurich. I merely added a few relevant recent references.) Nowadays, for the first time, it is possible to study “nonlocality without signaling” 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, about from 1915 to 1925. We note that the very concept of “nonlocality without signaling” is totally foreign to the spirit of relativity, the only strictly local theory.
