Someone (madeofstarstuff?) was asking a while back about the significance of photon interactions to our understadnign of reality
I am still interested in this topic. I only just now found this thread and decided to read it. I have a fair understanding of the diagrams you drew. As I understand it the positron is nothing more than an electron going back in time. The illusion (or reality) of a photon creating an electron-positron pair is really an electron going backward through time absorbing a photon that changes its energy so that it travels forward in time. Of course the two (electron and positron) are seen at the same time from our perspective, but they are the same electron? I've also read where perhaps all electrons are actually the same electron travelling back in time, seen as positrons in reverse and electrons forward. It went on to say that there aren't enough positrons to balance this so it must not be true. Nevertheless, that it confusing.
What I was originally wondering was, is the "shaking of hands" between electrons and photons and subsequent "scratching of the head" by electrons the only thing that produces our perception of time? I see at as though the photon instantaneously relocates itself from one electron to another. The electron then has to "decide" what information this photon is presenting, and then act accordingly. Perhaps this is crude, but is this "processing within the electron" what gives us the sensation of passage of time. It is responsible for the apparent "decrease" in light's speed through matter also, right?
There must be something wrong with this idea because photons traverse "empty" space through time without electron intervention. That is unless virtual particles (electron-positron pairs) popping in and out of existence are interacting with the photons again bringing rise to the sensation of passage of time. Whew, I'm confused.
