<abstract><p>In this work, we present the definitive unification between the 26-dimensional bosonic string model of Palumbo-Nardelli and the Nardelli-Miriam Theory of Everything (TOE) centered on the gravitational nexus ϕGN. We demonstrate that the 26D action serves as the primordial source for 10-dimensional local dynamics, stabilized by a “golden-locking” mechanism that forces asymptotic convergence toward the golden attractor ϕ*≈1.618665. By utilizing the Hardy-Ramanujan anchor (1729) and the 18th-root stabilization, we isolate discrete numerical values (256, 4096, 1728) that ensure the stability of wormhole throats and the horizons of supermassive black holes, such as the Gargantua type. Our results confirm the self-referential and fractal nature of the theory, identifying the sixth power of the golden ratio ϕ6≈18 as the precision trigger for dimensional reduction.</p></abstract>

<p>In this work, we present the definitive unification between the 26-dimensional bosonic string model of Palumbo-Nardelli and the Nardelli-Miriam Theory of Everything (TOE) centered on the gravitational nexus GN. We demonstrate that the 26D action serves as the primordial source for 10-dimensional local dynamics, stabilized by a &quot;golden-locking&quot; mechanism that forces asymptotic convergence toward the golden attractor *≈1.618665. By utilizing the Hardy-Ramanujan anchor (1729) and the 18th-root stabilization, we isolate discrete numerical values (256, 4096, 1728) that ensure the stability of wormhole throats and the horizons of supermassive black holes, such as the Gargantua type. Our results confirm the self-referential and fractal nature of the theory, identifying the sixth power of the golden ratio (6≈18) as the precision trigger for dimensional reduction.</p>
