Since upwards to 90-95% of the Universe seems to be dominated by dark matter/energy, I'm not sure the claim of finite complexity, except at very limited scales, can be made.
But even with a tiny amount of complexity, the initial value problem in the differentials means that some outcomes are essentially, non-deterministic. While the pattern of the dual slit experiment with electrons produces a distribution that is entirely predictable as a distribution, statistically speaking, for any particular electron, its ultimate location on the target is "uncaused" to use simplistic terms which further means nothing in our known universe specifically caused it to be where it ended up.
I think "cause and effect" are useful tools on some time scales but not others. The Big Bang didn't cause life, but merely produced an environment in which life as we know it could persist (at least for some number of years). There could very well be other perturbations in the dark matter/energy that will just as surely extinguish it. Whether this follows a pattern or not, is unknowable by us, by definition.
There is no reason to believe that dark matter doesn't experience its own "uncaused" perturbations which aren't knowable in the context of dark matter, but only in the context of really dark matter (stuff that only influences dark matter in a subtle way)... This fleas upon fleas upon fleas argument seems consistent with the observable universe. |
