Simulating the Cosmos

Context: Virtual ‘universe machine’ sheds light on galaxy evolution

A fascinating insight into computational modelling of simulating the Universe to approximate to an understanding of (a sub-set of) outstanding mysteries regarding galactic evolution.

Information/variables inevitably had to be compressed/abbreviated to permit sufficient processing power to conduct this simulation. What are the costs of this procedural or algorithmic compression for accuracy? Abbreviation generates (information) entropy and unknown factors, amplified by chaotic processes.

Also – working from within an incomplete (if extensive and compelling explanatory) framework of physics to produce models which approximate to provable theorems within the logical grammar provided by (those,) the current axioms of physical theory does seem a little circularly self-validating; this is perhaps an issue of science in general and something that can also be traced back to philosophical issues of logic and mathematics.
