Evidence is presented that cosmic expansion may have a role in creating the distinction between quantum and classical behavior. Within an extended object a spread of velocities may be expected to be present as a consequence of the cosmic (Hubble) expansion. This intrinsic spread in velocities is identified as a possible limiting factor responsible for quantum uncertainty in an object's behavior.
