The evidence for the Klein-Block Flip is found in the perfect symmetry of the laws of physics.
- CPT Symmetry: The fact that the laws of physics remain identical if you reverse charge, parity, and time suggests that the universe is fundamentally symmetrical at its boundaries.
- The Flatness of Space: The observed absolute spatial flatness (Ω = 1) is the geometric manifestation of global topological closure. Rather than a contingent byproduct of inflationary stretching, flatness is a strict boundary condition: for the 4D Klein block to loop back onto itself without metric disruption, the spatial geometry at the conformal suture must be perfectly uniform and uncurved to preserve the Identity Constraint (A = A).
