i think the thing that we need to explain is why what abstractions are and what they are as physical things. Because ofa, all human history, we've thought that there ware these properties that are a disembodied exist outside of the universe. And really, they do exist in the universe, and we just don't understand what their physics is. We do theoretical physics with math, but imagine doing physics of math, and then think about math as a physical object.
