# Is observability restricted by scale ?

I read somewhere something about observability, and things which are infinitely big, or infinitesimally small.

Basically, the question is whether it would be possible to make an observation of an infinitely long yardstick. If it existed, could you observe it in it's entirety ? is it possible ?

Same argument for the infinitessimally small, disregarding Planck length for the moment - would it even be "possible" to observe the infinitessimally small ?

Thanks,
