The first guess does not quite work
Could the phase transition have a space-time description at the level of basic TGD?
Light-like 3-surfaces from det(g_{4})=0 condition
Can one allow macroscopic Euclidean space-time regions
Conformal confinement at the level of H
But are the normal components of isometry currents finite?
det(g_{4})=0 condition as a realization of quantum criticality
