Einstein Equation from Coherence
Definition
In ODTOE the Einstein equation G_μν + Λg_μν = (8πG/c⁴)T_μν is derived as the Φ-self-consistency condition on pairs (g, T) — a fixed point of the configuration map Φ_C. The metric g_μν is the observer-correlator, the stress-energy T_μν follows from the observer action S_obs = ∫B²(1−σ)Λ√−g d⁴x, and Λ is a closed function of global coherence S*, matching Planck 2018 within 0.05σ.

Cognitive Coherence B(O,C)
Cognitive coherence B(O,C) is the central measurable quantity of ODTOE that determines how strongly an observer O actualizes configuration C. It is computed as B(O,C) = F^w1 · E^w2 · (1−σ)^w3 · Λ^w4, where F is attention focus (fidelity), E is energy, σ is internal contradiction (entropy), and Λ is data quality.
Operator of Observation (Ô)
The operator of observation Ô is the action by which an observer actualizes a configuration C from the potentiality field Ψ. The fundamental ODTOE axiom is R = Ô(Ψ); the self-observation loop Φ = ι ∘ Ô closes reality back on itself.
Dark Energy as Parent-Proton Merger
ODTOE identifies dark energy with the process of parent-proton mergers at recursion level d=12 in the matryoshka structure, regulated by a scalar field χ(x,t). The cosmological fractions Ω_Λ : Ω_DM : Ω_b = φ² : 1 : Z = 68.86% : 26.30% : 4.83% follow from π and φ with zero adjustable parameters and match Planck 2018 to within 0.54σ.
