Quantum Graphity Models

  1. Jan 20, 2013 #1
    Hello all

    After reading different things about Bell inequalities, EPR like experiments and the tension with relativity I have discovered the quantum graphity models (http://arxiv.org/abs/hep-th/0611197) where locality and geometry are not fundamental in the Universe and appear only after a phase transition.

    As far as I know at the moment it is only a model, similar to Ising one, and not a theory.

    However it recovers some intuitions that are growing in my mind after reading more and more about these topics:
    1. Locality has only sense in a geometry (where a distance can be defined)
    2. Locality is not fundamental or at least it is violated in certain circunstances (EPR, interaction free measurement, delayed choice etc)
    3. In consequence geometry it isn't fundamental either.

    My only question with this model is the existance of an external time, which is odd for me.

    What are your ideas about these kind of models?
