This is a summary of the way I see the universe.
Free Will:
The real question that all fundamental belief structures must address. In my version of The Way Things Work, free will is both very real, as well as being totally nonexistent. On first statement, that of course seems to be a paradox, but let me elaborate. I'm a big believer in divergent, or parallel universe theory (in this case, the model is rather unimportant.) The way I see it, each single instance of reality in a multiverse is a probability. There is a number that defines exactly what will happen, from beginning to end, in that reality. Given the complexity of a universe, and the supposedly infinite number of parallel universes, these probabilities are able do be described in a finite way, but are infinite in number.
Free will is effectively an illusion, since the universe that you are experiencing is described by a set probability, but in this case, your decision, and therefore your will, is both described by, and describes the probability, shaping the reality that you perceive. In this model, the actual probability that describes a universe is impossible to compute until the reality has ended, at which time, the point becomes mute.
And therein lies the problem, this makes so much sense in my head, but when I read over this after typing it, it seems to be gibberish. I hope somebody will get the gist of what I'm trying to say, and I hope to hear questions and comments from anybody who is interested.
