Hair splitting? I hardly think so. That’s too close to confirmation bias.
If you look at the hyperphysics page on light you’ll find many frequencies of color A and color B mixing to match one color C. Our eyes only measure the energy and call that a color.
low A (the lower frequency) + high B (the higher frequency) equals high A (the lower frequency) + low B (the higher frequency).
If anyone can see both the energy and the interference pattern then they could tell them apart. It seems that most people can’t.
But there you have a case where information is destroyed because it is indistinguishable.
If anyone can produce a cellular automata model that can create circles like those which relate to the inverse square of distance or the stuff of early wave mechanics, I think I can bridge the MWI view and the one universe of many fidgetings view that I cling to. I know of one other person who has a similar idea, unfortunately his idea has a bizarre quantity which is the square root of a meter.
