However, Smolin does not mean ordinary hidde-variables interpretation of
quantum mechanics when he says hidden-variables theory. In Loop Quantum
Gravity to which he is referring, there are no hidden variables in the
sense of traditional hidden variables interpretation, i.e. in the sense
of variables "behind" the quantum mechanical states that would imply
that quantum mechanical states on their own would be an incomplete
description of the particular quantum system. In LQG, quantum states are
considered as complete description, in contrary to tradional
hidden-variables interpretation.
When saying hidden variables, Smolin means something different, namely
the existence of a preferred frame of reference, which is hidden in that
way that, at least in the classical limit of LQG, we cannot observe it,
but observe a world where the relativity principlies seems to apply
instead. In some way, this is comparable to Lorentzian Ether Theory,
where a preferred frame of reference is given by the ether, but is
unobservable for us.
