"Would it be reasonable to assume that the same applies at the opposite end of the spectrum: from the sub-atomic to the super-galactical?" I suspect that its what we don't understand about quantum mechanics what finally will explain the macro observations that we don't understand. After all, macro observations have to derive from the fundamentals and it seems that the fundamentals are in the quantum realm.
