Macroscopic Teleportation in a Closed System: A Formulation via Riemannian Geometry, Quaternions, and Traversable Wormholes

The teleportation of macroscopic matter remains one of the most challengingopen problems in theoretical physics. Quantum teleportation, though experimentally verified Bennett et al., 1993, transfers only information, not matter itself;moreover, the scale required to describe a human being (approximately 1027 atoms)renders any copy-and-destroy approach entirely impractical. Traversable wormholes, proposed by Morris and Thorne 1988, offer a geometric alternative, but faceobstacles of global topology, distributed exotic matter, and gravitational instability.We present an alternative and original formulation: macroscopic teleportation via wormhole in a closed system. The central idea is to reformulatetravel as a process in which the interior of a “travel capsule” remains completelyisolated from the exterior throughout the journey A → B, with a causal validation protocol applied a posteriori at B verifying the conservation of energy, charge,and momentum. This reformulation reduces the problem of global topology to acoordination problem between two points — conceptually far more tractable.To express spacetime coordinates in a unified way we employ quaternions q =t+xi+yj+zk, encoding time and space simultaneously in a single algebraic object.Quaternionic interpolation along the wormhole provides a natural parametrisationof the internal trajectory. Finally, we present a computational analogy in Q#that illustrates the logical structure of the protocol without claiming to simulategravity.The five original contributions of this formulation are: (1) the closed-systemconcept as the central organiser of the protocol; (2) causal validation as a concreteoperational procedure; (3) quaternions as a unified language for spacetime; (4) thereduction of complex topology to A → B coordination; (5) the conceptual integration of Q# and General Relativity. We discuss honestly the physical and engineeringobstacles that separate this formulation from any practical implementation.
