  We demonstrate that in a globally deterministic universe, all
spatiotemporally symmetric processes must obey counterfactual parameter
independence. We show that the Tsirelson bound can be derived from
counterfactual parameter independence. We show that the quantum monogamy bound
can also be obtained from global determinism, and then then use these results
to propose a novel solution to the horizon problem. We also explain how global
determinism relates to contextuality in quantum mechanics.
