Mar 7, 2017 at 5:55 comment added sqykly I don't quite buy the bit that the barrier material's only possible attribute is opacity. Rather, I should hope to be able to set up an experiment that will measure the beam in terms of its conservation. That means a reflective or photometric material would affect the result whether conservation is measured explicitly or implicitly, i.e. not at all.
