    Discussing Lee Smolin's Non-Local Beables: Quantum Physics Emergent from Gravity

    Hello Jim, He certainly is not a crackpot. That's not a fair response to this paper, yes it is a philosophical paper. That Quantum mechanics is emergent is not entirely new as you may know, an the non local nature of quantum mechanics is a reasonably correct and good description of measurements...

    http://arxiv.org/abs/1507.08576 Non-local beables Lee Smolin (Submitted on 30 Jul 2015) I discuss the idea that the beables underlying quantum physics are non-local and relational, and give an example of a dynamical theory of such beables based on a matrix model, which is the bosonic sector of...

    http://arxiv.org/abs/1503.08814 Long-lived resonances at mirrors Friedemann Queisser, William G. Unruh (Submitted on 30 Mar 2015) Motivated by realistic scattering processes of composite systems, we study the dynamics of a two-particle bound system which is scattered at a mirror. The physics of...

    The 'time oriented coarse graining' hypothesis -- "Rovelli"

    But would a bouncing state of the universe in the past or the future not also inhabit the same marcroscopic variables questions as discretenes states and continuüm problems whe have now in our theoretical physics descriptions of these situations. It would be interesting to see if there is a way...

    The 'time oriented coarse graining' hypothesis -- "Rovelli"

    Remembering historical events or measuring them, is quite patchy or grainy if you like, never exact in a way that al information is available.
