Background: Our mental models of the universe can contain uncertainty or probability-links, as in a causal network. One may have a deterministic understanding of a phenomenon if the probability-values are all 0 and 1.
Question: Beyond that, is it meaningful to distinguish whether or not the *universe itself* is deterministic or nondeterministic?
For example, is it meaningful to say that the Copenhagen interpretation of QM implies a “nondeterministic universe”, while Many Worlds implies a “deterministic universe”?
[Question] Is “physical nondeterminism” a meaningful concept?
