I see. So me and my parent are both wrong. The problem isn’t about a lack of bridge, or inconsistencies/incompleteness, it is about a lack of well defined scopes for each theory.
In a sibling post I talk about how this is not a problem in psychology, and ask what the difference is. This answers that question kind of well, the difference is that in psychology/sociology the scopes are well defined. We know what a population is and apply sociology to it, and we know what an individual human being is, and apply psychology to it.
With quantum mechanics and general relativity the scope is supposed to be the cosmos, but both theories fail on some places in the cosmos. So either the theories are wrong, or the scopes are wrong. I’m leaning towards the latter.
The problem is that scale is completely smooth. IF there were some strict scale at which each theory applies, as I said, you'd then have problems for phenomena that straddle that scope. You can always add an extra electron or atom to a clump, so you'd have objects oscillating between obeying one set of equations vs the other, which seems very very very hard to actually believe.
A similar problem actually exists in psychology vs sociology, though it seems you choose to ignore it. When you want to study the behavior of two human beings (say, a married childless couple), do you apply sociology or psychology? How about a married couple with children? An extended family?
Also, psychology has to explain how an individual human behaves inside of a population, and sociology has to explain how the behavior of groups emerges out of the individual psychologies of their constituents. If they don't do this, then either one or both theories must be wrong. To take an extreme silly example, if psychology predicted that no person would never choose to kill themselves for the sake of another; but sociology predicted groups of people regularly have members sacrificing themselves for the group - then one of the theories must be wrong, you can't just say "we apply one theory when talking to a man and another when talking about the group".

Well, no. That's not really possible here. The scopes can't be adjusted. The theories are wrong. They both must explain all physical phenomena, but neither does, therefore a more accurate theory exists which we have not found yet.
I just don't know if there's much value in trying to make an analogy to psychology here. Currently it seems to be getting in the way of understanding.
