My question is as follows:(adsbygoogle = window.adsbygoogle || []).push({});

A photon clock (two 100% reflective mirrors exactly parallel and photons whizzing in between) actually possible. My question is made assuming we could get the mirrors exactly parallel. So really, I suppose my question is:

Are 100% reflective mirrors possible to make in reality?

Thanks all,

Joe.
