Thanks for your comment. It seems that, at its fundamental level, the universe is not predictable. Now, it also seems that, if something were static, it WOULD be predictable. A calculator, given the same inputs, will give the same outputs. A regular computer, with the same inputs, will give the same results, albeit with a few bugs and occasional crashes. These things are predictable, and they, by definition, do not change. So...could it then follow that, if something is not predictable, it is not static? Something like a quantum computer? I am not privy to the minute workings of quantum mechanics. But from what I have read and seen, the movement of fundamental particles, while it can be summarized and quantified, cannot be completely pinned down. We cannot say "If the universe does this, it will then do this," or "This particle will now move here," at least not with 100% certainty. And if we can't do that...if we can't get the same outputs from the same inputs, can we say for certain that it does not change? And can we say that a computer, based on those fundamental elements, would not change?
I suppose the fundamental question is, why do we not understand quantum mechanics? Are our models just not good enough--is there some force we have not yet identified that would allow us to predict what happens with 100% certainty? Or, perhaps, is it that the universe, at its most basic level, is as changeable as the human mind?
