 QM Not something you get closure on. To comprehend it requires a revision of our understanding; you have to think on a different conceptual scale

 What kind of conceptual scale|?

Things on a very small scale behave like nothing that you have any direct experience about… things that are roughly 10,000,000,000 times smaller than a typical human being they do not behave like clouds, or billiard balls, or weights on springs, or like anything that you have ever seen. But everything including you and I are made up of these minute things.
