FROM QUARK ER DIPOLES TO EMERGENT GRAVITY (XXI v4)

Within the pregeometric FCD-RB (Folded Crunch Dipole – Reversed Big Bang) framework, we propose a unified, self-consistent ontology that bridges the sub-hadronic, leptonic, electroweak, and gravitational sectors without introducing disjoint conceptual layers or independent fundamental fields. We demonstrate that the light quark flavours (up and down) are not distinct elementary particles but rather two stable, quantized asymmetric massdistribution modes of a single fundamental Einstein-Rosen (ER) dipole, corresponding to the robust minima (λ − ≈ 0.3163 and λ + ≈ 0.6837) of a snap-through double-well potential. Electric charge is shown to be non-intrinsic, emerging as the geometric signature of the dipole’s mass asymmetry across the visible and mirror branes (the Trans-Brane Mass-Asymmetry Rule, TBMAR), while the electron emerges as the localized leptonic Rayleigh-type resonance of the minority-mass endpoint. The weak interaction is reinterpreted as the transition operator mediating well-to-well mass redistribution without altering the baryon’s topological B3 braid protection. At the macroscopic scale, the collective entanglement entropy of the closed dipole network is projected onto each brane through the Ryu-Takayanagi relation, providing the microscopic complement required by Jacobson’s thermodynamic emergent gravity. The global uniformity of Newton’s constant G emerges naturally because all dipoles are immersed in the unique, shared bulk temperature T bulk , while a single small parameter ϵ(z) governs the cosmic thermal asymmetry, predicting a testable dynamical G(z) and unifying gravity with dark energy as two distinct ports of the same bulk. Semiclassical limitations and precise observational pointers for Euclid/DESI-2 are explicitly catalogued.
