The same thing is true for lead, on a smaller scale. Instead of feet of glass that the photon can pass through, you have fractions of a millimeter of lead. The light will penetrate that far, and if you can hammer out the lead thinner than that fraction of a millimeter, the lead will be transparent.
I'm guessing we are using a useful version of pass through where we do not insist that we have an infinite thickness of medium where nothing can pass through.

Anyways, a finite amount of lead can not completely block off light. Fire enough photons at it and eventually one will be lucky enough to get through.

Integral - the fact that Einstein did not agree with some interpretations of QM does not mean his views should be discarded - or that they were unfounded...Einstein, unlike you and a lot of the others who post on these boards, continually re-thought things from a conceptual perspective - his own contributions as well as those of others - and if you knew more about his life you would not say that he didn't keep up - he spent many hours thinking through experiments that would invalidate the Copenheagen interpretation
Indeed. The most powerful one was the so-called EPR paradox. It was conducted. Einstein was shown to be wrong.

Ah well. And that's the end of that.

Are we talking about a photon, or about wave theory?
Photons and wave theory are two sides of the same coin. Physics usually mean "em radiation" when they say light.
