The presence of cosmic expansion velocities within an extended object appears to lead to a fundamental threshold size that separates quantum behavior from classical behavior. This threshold is now examined further and interpreted in terms of diffusion processes in stochastic quantum mechanics. The limiting size separating quantum behavior from classical behavior is shown to correspond approximately to the object's stochastic diffusion distance over the Hubble time.
