    "abstract": "Recently, what appears to be a fundamental limit associated with the size of\nan object that separates the quantum behavior characterizing small objects from\nthe classical behavior characterizing large objects has been derived from the\nHubble velocity spread in an extended object. This threshold is now examined\nfurther and interpreted in terms of diffusion processes in stochastic quantum\nmechanics. This limiting size that separates quantum behavior from classical\nbehavior is shown to correspond approximately to the diffusion distance of the\nobject over the Hubble time.",
