Heyo, I'm not sure if this is the proper place to post this question, but as far as I could tell it's the closest place to appropriately do so. Anyways, here's the question; Are all isolated, deterministic systems inherently recursive? Keep in mind by isolated, I mean completely closed off and... self sufficient, with no external influences. I realize such a thing is practically impossible unless I'm talking about the system of all systems, i.e. the universe, which... I suppose I am. By deterministic, I mean hard, unforgiving determinism with no sympathy towards weaker forms of it, etc. Thanks everyone!!
