With many things in science, there isn't anything like that degree of incomplete information. We can talk about, say, a chemical reaction with extremely high certainty.

Also, in many cases a theory provides implicit context which makes the resulting statements true in the context of that theory. We can say that in general relativity, a black hole has a singularity at its center. There's no doubt about that, but it doesn't tell us whether actual physical black holes contain singularities.
