Reactive Substrate Theory: Core Structural Summary
Reactive Substrate Theory: Core Structural Summary
1. The Core Philosophy: Physical Restraint
RST treats the universe not as a passive mathematical stage but as a reactive substrate with finite operational limits. Standard physics (GR and QM) allows unbounded response — singularities, infinite densities, divergent curvature — because the equations themselves impose no structural ceiling. RST introduces the Universal Capacity Law (UCL), a physical admissibility filter ensuring that no state can exceed a maximum structural stress Smax.2. The Unified Structural Stress Scalar S(x)
To measure total substrate load, RST defines a frame‑invariant scalar combining the three major failure modes of physics:- Geometric Term: curvature stress (Kretschmann-type invariants). Prevents geometric singularities.
- Quantum Term: local energy density fluctuations. Prevents unbounded stress‑energy accumulation.
- Entropic Term: entropy/information gradients. Enforces holographic and Planck‑scale resolution limits.
3. The Skeletal RST Field Equations
RST uses a coupled PDE system where physical fields load the substrate, and the substrate’s saturation constrains the fields.Substrate Equation (S‑Field):
∂²S/∂t² − c² ∇²S + β S³ = σ(x,t) FR(C[Ψ])
- β S³: the hardening spring — substrate rigidity increases as stress rises.
- σ(x,t): the noise floor — the minimum resolution of the substrate.
Field Evolution Equation (Ψ‑Field):
∂²Ψ/∂t² − v² ∇²Ψ + μΨ + λ|Ψ|²Ψ = κ S Ψ
- κ S Ψ: saturation feedback — as S → Smax, field growth is suppressed.
4. Physical Implications: The RST‑Star
RST replaces singularities with finite, saturated structures.- No Singularities: infinite density is replaced by a finite saturated core.
- RST‑Star: gravitational collapse halts when the substrate reaches its yield point, producing a stable, high‑density extremal object where S → Smax.
- Event Horizon Reinterpreted: not a geometric trap, but a response boundary — the radius where substrate update bandwidth is fully consumed by local stress.
The Final Takeaway
Reactive Substrate Theory is a theory of restraint. It does not add exotic particles or extra dimensions; it removes the structural permissiveness of unbounded mathematics. When a calculation runs to infinity, it has not discovered a physical reality — it has simply exceeded the capacity of the substrate’s slide rule.The Universal Capacity Law: Bounded Response as the Missing Structural Term in Fundamental Physics
