Suppose there is a non-iterative non-recursive formula for calculating the state of a deterministic universe at time t.

I don't think this argument works, because any interesting universe would have physics that allow the implementation of arbitrary Turing machines, and there is no non-iterative non-recursive formula for calculating the state of an arbitrary Turing machine at time t.

Doesn't this imply that no finite universe is interesting?
