Examples of things that seem to happen for no reason at all, things acribed to "chance," are just where we do not have a full understanding of everything involved
Yea, Einstein felt a bit like that. He didn't like quantum mechanics and constructed a lot of arguments against it. However, the various things he tried have been shown to be wrong.
So it maybe that more learning about things will change this but so far it doesn't look like it. That seems to be the way things are.
If the universe had a beginning, as the big bang suggests, then it is an effect, because something had to cause it to come into being.
LOL, no no that is such totally circular it doesn't work. Things that are effects have to have a cause, by your definition but since some things are not effects and don't have causes you have to show that the universe is an effect not just declare that it is.

I'm not sure but this grew out of one of the thought experiments of Einstein that he felt showed a problem with QM. It was then felt to be impossible to perform the experiment. However, it was possible and Einstein was wrong.
I'm not sure what that says for the underlying ideas beyond this particular issue. We need a real physicist for this one.
I seem to recall that quantum effects can, in principle, occur on any level. It's just that the probability becomes less and less, the higher you go, so that eventually they become virtual impossibilities.
Have you ever seen anything on liquid Helium? It has quantum effects at a macro scale.
