      It requires at its heart understanding wtf the QFT formalism is describing

      There’s a great PSE post on this.. take the field operator φ³.. as a field operator it’s not even clear what this even means

      Lmao yeah it’s pretty hilarious to see the PSE answer questions about physical significance of X, where we have the most abstract mathematical formalisms as far divorced from human experience as possible

      Though if I’m not mistaken the S matrix and correlation functions and the invariant matrix element are essentially the same thing with different names

      The smatrix is just a correlation function with some extra creation and annihilation operators

      Hmm I guess the path from correlation function —> Smatrix seems to involve changes in information to me. Like if it was only a Fourier transform I’d be able to conceptualize how they’re the same, but I have a hard time of doing so now

      You’re right about that ontologically

      Yeah I think this could be a weakness of structural realism, but no matter how much I think about it it’s still hard to say anything that makes sense ontologically of correlation functions and the other mathematical objects/processes that we’re dealing with

      Possible that there are better questions to ask: does this have physical significance? Yes. Should we expect it to be preserved in a more fundamental theory? Yes. Then, here’s why....

      But the question of what is being preserved isn’t even obvious lol

          Yeah I think it’s still more tractable than asking “what do these mathematical objects, and the particular values this function takes, say the world is like?” I’m unsure if we even have the conceptual resources as humans to answer that

          That said, I guess you can still say stuff like “quarks exist” and be counted as a realist
