I have recently come up with a construction of a BW which is perfectly consistent with the statistical predictions of QM on the one hand, and with macroscopic classical mechanics and an arrow of time on the other hand.
Key features of the BW, overlooked in the above discussion, include:
– The BW must not admit a formulation in terms of as a Cauchy initial value problem, or else Bell’s inequalities would be respected.
– Quantum randomness arises naturally if one realizes that experiments are never repeated. Each repetition corresponds to a different slice of the BW, supported on different times, and QM merely describes the statistical properties of ensembles of such slices.
– The BW must include both a macroscopic radiation arrow of time and a local energy-momentum conservation law for it to be compatible with classical physics.
