If our physics is actually deterministic,

Then

- how do you measure with sufficient accuracy to (well) beyond the Heisenberg limit, everything within a relativistic radius in order to counter chaotic turbulence

and, then, once you have done so,

- how do you compute forward the rather large number of "grains" just measured in the fine time steps required to counter chaotic turbulence?

Leaving aside just how difficult (against the scale of the universe) such exercises are, let's return to the mathematical certainty of proof by both Lorentz and Smale ... any tiny deviation, even magnitudes of order finer than Heisenberg will eventually bite any claim to the certainity of determinism hard in the arse.

And yet it's unknowable.
