Tong's key point in December's 2012 Scientific American is that chiral fermions needed for the weak force cannot be computed in lattice gauge theory.
This seems an odd claim unless Wilzcek's QCD for strong gluon-quark force is not at all able to deal with the weak force?
So that would mean the quarks in QCD are not chiral?
Will some expert please pipe in on this?

  • Jack Sarfatti David Tong says that the movie Matrix does not describe reality. That we really are analog not digitally simulated by the Omega GOD(D) cosmic computer on our PIXELATED dark energy future event horizon as I have been speculating.

    Tong writes: "We can
    handle all types of hypothetical fermions but not the ones that actually exist. Fermions in the standard model ... that spin in a counterclockwise direction feel the weak nuclear force, and those that spin in a clockwise direction do not."

    So do the Wilczek strong force QCD lattice computations completely ignore weak force effects? QCD modeled fermions are not chiral?

    Tong ends his article: "We are not living inside a computer simulation."

    Tong also says that we cannot simulate chiral fermions on the computer- but does that not contradict Frank Wilczek's lattice QCD hadronic mass computations? What is going on here?

    Quantum theorists often speak of the world as being pointillist at the smallest scales. Yet a closer look at the laws of nature suggests that the physical world is actually continuous—more analog than digital
