A Dual-Domain Cosmology: An Ontological Foundation for General Relativity and Quantum Field Theory

For decades, general relativity (GR) and quantum field theory (QFT) have remained conceptually incompatible — one describing gravity as geometry, the other describing particles as quantum excitations. No consensus exists on how to unite them. This paper proposes a unifying ontological interpretation that bridges this divide.

The core thesis is that quantum entanglement is fundamental, residing in a timeless, non-local Quantum Domain (QD). Our observable Spacetime Domain (SD) emerges as the geometric expression of entanglement transduced across a QD–SD interface governed by a maximum geometric transduction speed (MGTS) — the invariant speed limit operationally measured as the speed of light in vacuum. The domains are seen as the sides of a same coin.

This single framework offers novel and unified explanations for phenomena across scales — from fundamental physics to cosmology — linking them all to quantum entanglement. It reinterprets relativity, cosmology, quantum foundations, and the deepest mysteries of the universe through a single guiding principle. This work does not offer mathematical formalism — it is an invitation to complement this model — but provides the first unified ontological lens connecting the very large with the very small.
