The goal of this contribution is to relate quarks to knots or loops in a 6-space CP 3 that then ollapses into a torus in real 3-space P 3 instantaneously after the Big Bang, and massive inflation, when 3 quarks unite to form nucleons. IntroductionKedia et. al. in recent paper [10] investigate knotted structures in hydrodynamic fields such as current-guiding magnetic field lines in a plasma, or vortex lines of classical or quantum fields which arise naturally as excitations that carry helicity that is a measure of the knottedness of the field. In particular their Fig.2g is a trefoil which is our Fig.3 without the quadrupole (that will be seen in Section 2 to collapse into a point) and the color-coding.
