How I can prove God exists, sort of.
Scientists have a problem called the cosmological constant. This is a reference (as I understand it, and this disclaimer applies to everything I say here) to the level of inherent energy in the vacuum of spacetime. If lower, the stars and life could not form. If higher, all would fly apart and life would be impossible. I think I have that close to right. In any case, because the cosmological constant is balanced so perfectly, impossibly perfectly, they are troubled by this fact. Some have said this has to point to a higher intelligence, i.e. God, to have so many things so perfectly tuned for existence to work.
The solution comes in the form of Multiverses , and the Many Worlds theory, which may be two perspectives of the same thing. The Multiverse theory is that this is only one of an infinite number of universes, each with its own set of physical laws and circumstances. To make sense of our perfect situation, it is said that we just happen to be the one that worked among the infinite number of those that didn’t, at least the same way. In this scenario all possible (or should I say impossible) universes must exist. An infinite number, for us to have occurred. This means much the same as the Many Worlds theory puts forth. In that case, the timeline of your life is a constant selection of choices every instant, and a constantly new number of “yous” follow every possible choice path; an endless infinite branching of your timeline.
Now consider what this means, and what they say about this which may sound ridiculous. Every scenario you can possibly think of exists in one of these worlds. In one, you are Hitler. In another you are long dead, or never been born. In another we never became human, and another we are gods. Whatever. So you see, this doesn’t sound sensible whatsoever, but the vast array of universes don’t care what we think sensible.
Now in one of these universes, there exists, beyond any doubt, a god, in fact God, if all possible worlds exists. And this god is the God of all the timelines and all the multiverses. And so God exists. And if theses theories are as foolish as they sound, and wrong… what then? We are left with the conundrum that our set of circumstances are too, in fact, impossibly balanced. What then?
Here’s what I think, lowly as my educational and intellectual status might be. First of all, regarding infinite timelines and free will: The past is recorded and done. It existed but is now a static record that helped to establish the present. The future is potential, and its path, though there are many possibles, is not yet established. The future is potential, in the same regard as wave function in quantum mechanics. The present is dynamic, and is the current state of the universe as determined by the past state, and entropy and past choices. The present, along with the current state of the universe, and flow of entropy, is also dynamic with an infinite web of events and choices, which collapses the wave function and determines the next instant of the state of the universe. It is like a rolling wave or a turning wheel, where the present is where the wheel meets the ground.
And what of God? Well, personally, I think we have a problem. What IS God? I feel we have not truly defined what we even mean. Oh, we have this childish mythical figure we use in our minds, and that is forgivable because the concept of God is really, by “definition” well beyond our ability to comprehend. Here is what I think. In the old testament Moses ask God his name. God’s reply is something akin to “I Am.” And thus you have it. God Is existence. The Mystery buried in existence, and there is nothing more difficult to understand then that.
