Regarding infinite states, let's assume infinite storage capacity and a time step approaching 0 (in the limit sense:. It's not science, it's math. Regarding science, the point is not knowing. Science isn't just answers, it's a process for finding new questions to answer. Something could always come along that radically changes our understanding of some aspect of the universe, but that doesn't necessarily mean what we knew before was wrong, just incomplete. If an old theory explains everything measured up to a point, the old theory is still "right" within the context of those measurements. A new measurement that invalidates the theory doesn't invalidate the previous measurements in almost every case. It's also important to distinguish between math and science. Mathematicians can make definite claims to correctness because they study "universes" of their own creation. Science only claims correctness in light of current knowledge, within certain error bars. Ignore sociology. |

I concur, but my point is that with regard to the mechanics and composition of the universe in which we live it would seem that the more we measure the larger those error bars appear to be. Every once in a while measurements come along which multiply the size of those error bars exponentially and once that happens scientists should take note to adjust the English language they use in characterizing the limitations of their own knowledge. Modern scientists seem to be notoriously slow at this and my suspicion is that this is because it would give the impression that certain fields of science are becoming less knowledgeable as time goes on, and that's not good PR. In other words my only complaint here is related to sociology, the use of language.
Thank you for prompting me to refresh my memory on the differences between mathematics and scientific inquery because in so doing I ran across a quote having to do with the role of the theorist (my favorite) who is caught between the two worlds:
"Before an experiment can be performed, it must be planned — the question to nature must be formulated before being posed. Before the result of a measurement can be used, it must be interpreted - nature's answer must be understood properly. These two tasks are those of the theorist, who finds himself always more and more dependent on the tools of abstract mathematics. Of course, this does not mean that the experimenter does not also engage in theoretical deliberations. The foremost classical example of a major achievement produced by such a division of labor is the creation of spectrum analysis by the joint efforts of Robert Bunsen, the experimenter, and Gustav Kirchoff, the theorist. Since then, spectrum analysis has been continually developing and bearing ever richer fruit." — Max Planck
