Logarithmic-Spiral Tubular Wormholes in Einstein–Cartan–Maxwell Theory: The End of the Exotic Matter Paradigm and the Torsional Shield Theorem

Key Points

To create a dynamically stable, traversable wormhole without relying on exotic matter.
Developed an analytical model of a wormhole using Einstein–Cartan–Maxwell theory.
Utilized logarithmic-spiral tubular geometry for model construction.
Formulated the Rossetti–Geometric Autonomy Theorem and Torsional Shield Theorem to support findings.
Established a stable and traversable wormhole design without the need for exotic matter.
Introduced a natural repulsive barrier that ensures stability across various scenarios.

Abstract

A complete analytical construction of a dynamically stable, non-exotic traversable wormhole in Einstein–Cartan–Maxwell theory. The geometry is based on a logarithmic-spiral tubular embedding, leading to the Rossetti–Geometric Autonomy Theorem and the Torsional Shield Theorem, which establishes a natural repulsive barrier ensuring dynamic stability without exotic matter.
