    "abstract": "We discuss how to embed quantum nonlocality in an approximately classical\nspacetime background, a question which must be answered irrespective of any\nunderlying microscopic theory of spacetime. We argue that, in deterministic\nhidden-variables theories, the choice of spacetime kinematics should be\ndictated by the properties of generic non-equilibrium states, which allow\nnonlocal signalling. Such signalling provides an operational definition of\nabsolute simultaneity, which may naturally be associated with a preferred\nfoliation of classical spacetime. The argument applies to any deterministic\nhidden-variables theory, and to both flat and curved spacetime backgrounds. We\ninclude some critical discussion of Einstein\u0027s 1905 \u0027operational\u0027 approach to\nrelativity, and compare it with that of Poincare.",
