Oh, and I forgot to mention: once we have a subset of universe-rules, taken as provisionally-valid because they all exactly match ongoing experiment, *then* we also have a more refined map of 'which *differences* between universe-rule-particles are there, which we can *design* experiments to resolve?" Limiting the set of possible theories gives us a much more efficient and directed roadmap for experimentation and necessary instruments.

Then, if we have such few remaining provisional-universe-rules, we can ask a question of ALL of them: we will get a smattering of different responses, ambiguous. Yet, that small set of different answers is *much less uncertainty than a continuum*; we may not know the truth, but we can be reasonably confident in a handful-of-possible-outcomes, *even when we DON'T have an experiment to validate them*. Like forecasting a hurricane - we'd get a few different predicted 'tracks' for dynamics, when we run the simulations, even when we don't have instruments for that particular system.
