  Now, recall (section 5.3.1) that Bohm's theory reproduces the quantum statistics by postulating the quantum-equilibrium distribution over the positions of particles. If this distribution is not an accidental fact about our universe, but rather obtains as a matter of law, superluminal signaling will be impossible in principle. Dürr, Goldstein and Zanghì (1992a,b, 1996, fn. 15) argue that, while the quantum-equilibrium distribution is not a matter a law, other distributions will be possible but atypical. Thus, they conclude that although superluminal signaling is not impossible in theory, it may occur only in atypical worlds. On the other hand, Valentini (1991a,b, 1992, 1996, 2002) and Valentini and Westman 2004) argue that there are good reasons to think that our universe may well have started off in a state of quantum non-equilibrium and is now approaching gradually a state of equilibrium, so that even today some residual non-equilibrium must be  present.[32]   Yet, even if such residual non-equilbrium existed, the question is whether it would be possible to access any ensemble of systems in a non-equilbrium distribution.
