Ok, I've been taught this stuff in school about the particle/wave duality. And what's been always bugging me is that it doesn't really tell me anything : I want a theory that is cohesive without compromises. SO...I was shown an experiment similar to Young's 2 slit experiment. It has a half silvered mirror and a laser. The "/" is the half silvered mirror. __ . . (single photons)................../........| Basically, you think...well the photons come out of the laser, hit the mirror, and either go North to one Mirror or East to the other. They bounce off, there's some slight angles, and head for the detector. The thing is, even though only 50% of the photons go to each mirror, if you move EITHER mirror it changes the time it takes for ALL of the photons to get to the detector. Well, ok, so that is tough to understand. Obviously, every photon must take BOTH paths. If you change the two mirrors to detectors, then any given photon only is DETECTED by one detector. Yet, when the light wave is at the mirror, it can't know a detector is waiting for it. So the laws of physics must be the same : the light does NOT pick a path because it is GOING to be observed, it STILL goes both ways. Just, when it gets to a detector, the photon has been split, and so has half the electromagnetic field strength. It randomly "chooses" whether to give all of it's energy to the detector, with the probability varying by the light's field strength. This theory requires instantaneous communication along individual photons : every piece of the spread out photon must "know" that it is being absorbed somewhere. However, you cannot use this instantaneous communication for practical purposes. I talked to some TAs, and they said I should write up my "theory" in mathematical terms. Ha!, whatever. I don't have time in my lifespan to go to Caltech for 5 years to learn the math needed for quantum mechanics directly. Plus, the math is bullgarbage : it's like string theory. The blackboard full of equations is just a model of what is going on, not what is physically happening.
