Reactive Substrate Theory An Interpretive Constraint Framework for Modern Physics ________________________________________ Chapter 0 — Methodology & Interpretive Scope Reactive Substrate Theory (RST) does not function as a predictive physical theory and does not compete with General Relativity, Quantum Mechanics, or Thermodynamics. It introduces no new equations, alters no established formalisms, and proposes no alternative dynamics. Its contribution lies entirely in the domain of interpretation. RST operates along an orthogonal methodological axis. Where standard physical theories map initial conditions to outcomes through dynamical evolution, RST restricts the class of interpretations that may be treated as physically admissible once finite, nonlinear, and dissipative response is enforced. This distinction is essential. Mathematical allowance does not imply physical realizability. A formalism may permit extensions, limits, or continuations that violate the constraints imposed by...

5.3 Horizons as Response Boundaries, Not Geometric Mysteries

5.3 Horizons as Response Boundaries, Not Geometric Mysteries Event horizons occupy a peculiar position in gravitational interpretation. Formally, they are among the cleanest structures in general relativity: null surfaces defined by causal accessibility. Interpretively, they have accumulated a dense halo of metaphysical speculation. This accumulation is not a consequence of the equations. It is a consequence of reading geometric boundaries as if they were physical agents. In general relativity, an event horizon marks the boundary beyond which signals cannot reach future null infinity. It says nothing, by itself, about forces, barriers, surfaces, or physical membranes. Yet horizons are routinely narrated as if they do something: trap information, block escape, or separate regions of reality. The RST Stripping: Causal Inaccessibility vs. Causal Mechanism Under RST, a horizon is not a place where gravity becomes infinite. ...

Stress, Saturation, and the Limits of the Geometric Picture

5.2 Stress, Saturation, and the Limits of the Geometric Picture The geometric reformulation of gravity in general relativity was motivated by restraint. Newtonian force was eliminated as a primitive, and spacetime structure was introduced as a means of encoding relational constraints on motion. As long as geometry remained descriptive , this reformulation succeeded remarkably well. The interpretive difficulty arises when geometry is asked to do more work than description alone permits. In practice, gravitational systems are often treated as if increasing curvature corresponds to increasing gravitational intensity in an unbounded sense. Strong-field regimes are narrated as regions where spacetime becomes progressively more active, more influential, or more extreme, culminating in singular behavior where the geometry itself is said to “break down.” The RST Standpoint: Identifying the Site of Failure Geometry does not fail ...

Geometry as Description, Not Cause

Chapter 5 — Gravity, Black Holes, and Breakdown Part I — Geometry as Description, Not Cause 5.1 The Persistent Mistake: Treating Geometry as an Agent Gravity is often described as the most elegant interaction in physics. It is also the one most persistently misunderstood at the interpretive level. This misunderstanding does not originate in general relativity itself. The Einstein field equations are precise, restrained, and extraordinarily successful. The difficulty arises in how their content is habitually narrated. The now-familiar slogan — “spacetime tells matter how to move, and matter tells spacetime how to curve” — is a useful pedagogical compression. It becomes a mistake the moment it is taken literally. Geometry does not act. Spacetime does not exert influence. Curvature is not a force. These statements do not challenge general relativity. They restore it. The temptation to treat geometry as a causal agent is understandable. General relativity replaces the ...
