Physics has spent a century trying to reconcile two frameworks that refuse to reconcile. General relativity describes gravity at cosmological scale. Quantum mechanics describes behavior at particle scale. Both work. Neither contains the other.
Cosmic Egg Theory does not approach unification by extending either framework. It goes underneath both — to the geometric substrate that forces both into existence.
The bilateral crossing structure at θ = π/8 is not a physical object. It is the prior condition that makes physical objects possible. The cascade it generates — 8, 12, 36, 108, 216 — is the address architecture that space emerges from. Physics happens at address 36.
Light is escaped crossing energy — the substrate pulled through the bilateral window and projected into the manifested universe. c is constant not because physics requires it but because the projection mechanism is constant. The window does not vary. The speed is the consequence, not the axiom.
The fine structure constant α⁻¹ = 137.035... is a property of the geometry — the ratio between the singular cosmological expression of the bilateral crossing and its quantum-scale repetition.
Confinement is a forcing condition generated by the geometry. The cone of observation leaves a necessary blind spot. Confinement forces bilateral input. Bilateral input forces the inversion operation. Inversion fills the blind spot. The geometry closes. This is not a modification of existing physics. It is an account of where physics comes from.
