LIGHT IS OF A FIELD, YOU MUST COP TO THIS. I may speak here, with one of my first 2005 studies being of a “photon wave packet”, A FINITE RADIATION. So what’n’ell am I talking about? Well, I just assumed there was a limiting envelope of charge. THIS WILL BE PRODUCED by the metal walls of a microwave chamber; IT WILL BE PRODUCED by atoms ready to emit or to radiate.
EITHER the vacuum localizes light like little bullets, or not. IF IT DID, THE DOUBLE SLIT EXPERIMENTS WOULD NOT BE AS THEY ARE. We record a photon event at some place on our film, or screen. WE MAY SAY NOTHING ABOUT WHERE THIS ‘photon’ WAS, A MOMENT BEFORE.
