Hang language. Can you give me a measurement procedure how you are
supposed to distinguish between these copies if your observation of
their spacetime trajectories is interrupted? Space itself isn't
labelled, nor are system's particles.
I'd presume otherwise identical objects is indistinguishable, since
space is rotationally and translationally invariant. (It's actually
not enantioinvariant, but you'll find that out if you look _very_
closely).
ciao,
