25 Relation to Existing Theories

Having established the internal consistency, numerical realizations, and falsifiable predictions of the framework, we now place it in context. This section compares the present theory with existing approaches in fundamental physics and clarifies both points of contact and points of irreducible difference.

25.1 General Relativity

General relativity describes gravity as the curvature of spacetime sourced by energy–momentum. It is an extraordinarily successful effective theory, confirmed across a wide range of scales.

In the present framework, general relativity is recovered as a limiting, coarse-grained description. Informational gradients generate effective potentials that can be encoded in a metric structure, reproducing weak-field and many strong-field phenomena.

However, spacetime curvature is not fundamental. It is a derived concept that loses meaning when informational propagation ceases. As a result, singularities are not physical infinities but boundaries of applicability for the geometric description.

General relativity is therefore not rejected, but demoted from a fundamental principle to an emergent approximation.

25.2 Quantum Field Theory

Quantum field theory (QFT) presupposes a fixed spacetime background and quantized fields defined upon it. While spectacularly successful in describing particle interactions, QFT does not address the origin of spacetime itself.

In the informational framework, spacetime and fields emerge together. There is no pre-existing background on which fields are quantized. Instead, particle-like excitations correspond to stable localized modes of the informational field.

This suggests that standard QFT should be understood as an effective theory valid within the structured phase, after locality and time have emerged. Attempts to quantize gravity within a fixed spacetime ontology may therefore be misdirected.

25.3 Emergent Gravity Proposals

A number of approaches propose gravity as an emergent phenomenon, including entropic gravity, induced gravity, and thermodynamic interpretations of spacetime.

The present framework shares with these approaches the rejection of gravity as a fundamental interaction. However, it differs in a crucial respect.

Most emergent gravity proposals remain entirely within the physical phase. They assume spacetime, entropy, and thermodynamics as primitives and attempt to derive gravity from them.

Here, emergence occurs one level deeper. The theory explains why spacetime, entropy, and thermodynamic behavior arise at all. Gravity is emergent not from entropy, but from informational structure selected prior to physics.

25.4 Why This Framework Is Not MOND

At first glance, the appearance of a universal acceleration scale $a_{\ast}$ may suggest a connection to Modified Newtonian Dynamics (MOND). This resemblance is superficial.

MOND is a phenomenological modification of the gravitational force law, introduced to fit galactic rotation curves. It does not explain why the modification exists, why the scale takes its observed value, or how it connects to cosmology and black holes.

In contrast, the present framework:

• does not modify force laws by fiat,
• relates $a_{\ast}$ to informational evolution via an explicit dimensional constant $\Lambda_a$ (Appendix E.3), whose value is not itself derived from the theory,
• explains dark matter, dark energy, and black holes within a single structure,
• makes independent predictions beyond galactic dynamics.

The Radial Acceleration Relation emerges here as a consequence, not an axiom. While MOND fits a subset of galactic data, it offers no account of the deeper structure addressed by the present theory.

Thus, this framework is neither a modification of gravity nor a dark matter model. It is a generative theory from which both emerge as effective phenomena.

With the comparative landscape clarified, we are now in a position to summarize the full scope of the theory and outline its implications for future research.
