    "abstract": "An explicit dynamical model for non relativistic quantum mechanics with an\neffective gravitational interaction is proposed, which, as being well defined,\nallows in principle for the evaluation of every physical quantity. Its non\nunitary dynamics results from a unitary one in a space with twice as many\ndegrees of freedom as the ordinary ones. It exhibits a threshold for the\nemergence of classical behavior for bodies of ordinary density on rather long\ntimes or instantaneously, respectively at around 10^11 or 10^20 proton masses.",
