You claimed that Faraday cages "cancel EM waves". I keep asking what this is supposed to mean mathematically, and you keep dodging. Do you claim that an EM sensor inside a cage can't detect a lightning bolt hitting the cage from the outside? How about sensor outside, bolt inside?

Take a photon or electron which travels down one of two paths. It doesn't emit lightning, but it does emit some EM waves I want to block. But I can clearly block this, in fact I don't even need the cage -- we do interference experiments all the time and it is impossible to 4/

tell which path the electron or photon took. If it was possible, we wouldn't see interference in double slit experiments. I also gave you the example of constructing the lab inside a deep potential so that nothing below a certain energy escapes to infinity. 5/

You called this a red herring, but it's not. You are claiming a fundamental physical law which prevents information from being kept local and I know of no such principle. You make reference to holography to back this up, but holography says nothing about this -- it is merely 6/

an equivalence of two theories. So if you are going to claim that physics doesn't allow events to be localised, please tell me what this physical principle is. 7/7
