That kind of mathematics - models of cellular automata -  is the
domain of the theory of computation.  These are just that - models.
But there is no reason for thinking that the models or mathematical
rules are identical to the physical entities themselves just because
these rules/models can precisely predict/explain the behaviour of the
physical objects.
