We give complete proofs of the main theorems stated. This paper presents a novel framework for characterizing the 3-sphere and proving the Poincaré Conjecture, circumventing the traditional tools of Ricci flow and geometrization. The approach is built upon two central constructs: the contact twistor bundle T(M), which encodes the conformal geometry of the 3-manifold M, and the interlaced homotopy network RH(M), the moduli space of SU(2) representations of its fundamental group. The main theorem establishes that for a simply-connected 3-manifold M, the following are equivalent: (1) M is diffeomorphic to S³; (2) T(M) admits an integrable (1,0)-type twistor Cauchy-Riemann structure; and (3) RH(M) is contractible, has isolated fixed points under a torus action, and its first cohomology group vanishes. The proof leverages the rigidity of twistor structures on S³ and a detailed deformation theory of representations to exclude exotic smooth structures. The work is extended to provide a complete classification scheme for 3-manifolds using combined twistor and physical invariants, and further generalized to offer twistor characterizations of spheres in higher dimensions.
