Information Substrate Theory (IST v4.2.0)

We present Information Substrate Theory (IST), a monistic ontological framework positing that
reality emerges from a discrete, non-orientable 2D information lattice (Σ). We reinterpret fundamental
physics: gravity arises from computational latency (τfold), and matter comprises stable topological
solitons. From these principles, we derive field equations with a variable gravitational coupling G(ρfold).
We show that the scaling of G with fold density is determined by the fractal dimension D of the substrate’s
projection into emergent 3D space: G ∝ ρ1/D
fold . Recent renormalization group calculations suggest that D
may be the golden ratio φ ≈ 1.618, leading to G ∝ ρ0.618
fold . We present simulation results demonstrating
key predictions: (1) a non-random antipodal correlation (C ≈ 0.005) in Planck CMB data consistent
with a weak non-orientable topology; (2) a suppression of gravitational lensing in cosmic voids whose
magnitude depends on D, with the φ case yielding a ∼ 76% reduction distinguishable from the earlier
√ρ model; and (3) a synthetic observation confirming that the COSMOS-Web JWST survey possesses
> 5σ sensitivity to test these predictions. We further introduce the Zero-Point Operator (Ω), a special
case of the Compression Operator acting at the manifolds self-intersection, which provides a geometric
foundation for self-referential information automata and bridges IST with computational architectures.
