PFUSR-35: Rational Conjecture of 11D Dual-Single Cone Ice-Cream Structure and Unified Coupling Valve System

Within the framework of the PFUS system, this paper proposes a rational conjecture of the 11-dimensional cosmic dual-single cone ice-cream structure: the upper part is a high-dimensional dual-cone structure, the lower part is a low-dimensional single-cone structure, and the whole takes the shape of an ice cream. At the junction lies a structurally compact region with highly concentrated physical effects—the waist region, which serves as the high-low dimensional coupling interface. It is clarified that a unified coupling valve system exists within this interface. Keywords: 11D spacetime; dual-single cone structure; ice-cream morphology; waist coupling zone; coupling interface; unified valve system; rational conjecture; topological consistency
