Yes, Virginia, theorems vary much, and there are still many uncertainties and unexplored "domains" to discover (and to be "analysed").
The butterfly effect reminds us that small causes can have larger effects, a combination of circumstances favours increased quantities, power and/or speed, for instance, and that, according to more simply expressed popular sayings, there is always the last straw which breaks the camels back, or that little strokes fell big oaks.
Bell's theorem shows that there will always be uncertainties and differences, as predictions are basing on eventualities. Lots of questions remain unanswered or have too many more or less different or even conflicting answers.
It makes sense that (citing)
"No physical theory of local hidden variables can ever reproduce all of the predictions of quantum mechanics."
Space, vacuum and time or influences seem to be real and unreal at the same time, much like our perceptions may be "misled", if referring to colours, objects, mirages or illusions we can see, touch, hear, smell or feel.
As I feel like talking nonsense today, I think that I will need to do deepen into the subject (Roosters suggestion looks interesting).
