If you search "ctmu" you'll probably find Chris Langan's website. Or search "megafoundation". He has written interesting stuff.
H: "Sum of histories, as I understand it, is related to Feynman's path integral formulation with the superposition of the probability amplitudes. I don't see any superposition of probability amplitudes in your example. Maybe I'm missing something."
I think probability amplitudes maybe are present in my example when you start looking at the possiblities of seeing the sum of histories from different perspectives. It would be about the probability density of finding a particular perspective when looking from some other perspective and trying to interpret a third perspective.
I don't mean "God" is ALL that exists; but that all that exists, exists through God.
I am not saying that there are strings say held together with glue; which would mean there are strings, and there is glue. I'm saying that there may be if you like, strings held together with glue, where there is an interdependence: the strings can only be strings when held together as something bigger than strings.
The glue and the glued stuff may need each other to be what they are; so Existence would be a relationship? A third entity, not the glue, nor the glued stuff; but projected by their relationship; might be said to exist.
"God is Three and God is One" comes to mind.
Actually it's interesting that quarks may be only quarks when they are combined into other things.
