Phenomenological Model of Emergent Gravity

We propose a unifying framework in which physical reality emerges from three hierarchical domains: a Primordial Bubble (P) of axioms, a 10-dimensional Middle Bubble (M) hosting a primordial tensor field IBA (), and a 4-dimensional Universe Bubble (U) obtained via holographic projection. A discrete Z₂ symmetry I -I forbids cubic instabilities, rendering the potential V (I) =12 m² Tr (I²) + (I²) ². In the low-energy limit, the linearised equations for I reduce to the Einstein equations for the metric perturbation g_=V₆\, I_, with effective Newton constant G₄₅₅= (16 m² V₆) ^-1. The six extra dimensions are stabilised by a combination of curvature, gradient energy, and a Freund-Rubin F₄ flux, yielding a radion mass m_ 1. 65 0. 15\;TeV. We explicitly show why this radion mass has not been excluded by LHC data (ATLAS/CMS) due to its large width _/m_ 0. 3-0. 5 and suppressed production cross section. The Standard Model gauge group and three fermion generations follow from an explicit orbifold T⁶/Z₃ construction, with a complete decomposition of the E₈ adjoint representation and the index theorem yielding N₆₄₍=3. Specific predictions include a radion decay ratio () / (gg) 0. 0053 and a gravitational decoherence rate g G m₀² c³² (x/LP) ² with 10^-2. abstract
