Observable 3D Reality as Thermodynamically Stable Condensed Phase of a 2D Quantum Substrate Dimensional Deployment Theory (DDT) proposes that observable 3+1D spacetime emergesas a condensed phase of a 2+1D quantum substrate through a deployment mechanismcharacterized √ by the exact parameter κ = 2. This yields the Ferreyra Constant ΦF =2 − 1 = 0.41421356... predictable to arbitrary precision.The framework addresses multiple observational tensions: H0 discrepancy (5.4σ inΛCDM reduced to 0.1%, κ ̸= 2, PCC failure > 5%,UV divergence detection, orbital decay ∝ η0v.
Carlos Ferreyra (Mon,) studied this question.
