\beginabstract Modern physics successfully describes how the universe behaves, yet remains silent on why this universe, with these laws and constants, exists at all. Fine-tuning, dark matter, dark energy, and spacetime singularities indicate that physical law cannot ground itself.

We present a unified generative framework in which physical reality is not postulated but selected. A pre-physical functional evaluates possible generative worlds and admits only those capable of sustaining coherent structure. Within the selected world, spacetime, gravity, matter, dark matter, dark energy, and black holes emerge from a single informational field governed by a nonlinear reaction–diffusion equation.

Absolute singularities are forbidden, information is never destroyed, and all dark phenomena are reinterpreted as informational phases. The framework is numerically implemented, confronted with galactic rotation-curve data, and yields falsifiable predictions for gravitational-wave ringdown signals. \endabstract

Introduction: The Limits of Postulated Physics

Contemporary physics assumes spacetime, fields, and dynamical laws as primitives. While empirically successful, this approach leaves unanswered why these laws hold, why constants are finely tuned, and why singularities and dark components arise.

These questions cannot be resolved from within physics alone. They point to a deeper layer governing which kinds of physical worlds can exist at all.

The Space of Possible Worlds

We define a space of generative worlds

$$\mathcal{W} = \{ W_i \},$$

where each world is specified by a triplet

$$W = (\mathcal{D}, \mathcal{R}, \mathcal{G}),$$

with primitive distinctions $\mathcal{D}$, generative rules $\mathcal{R}$, and a mapping $\mathcal{G}$ from possibility to structure.

At this level there is no spacetime, no energy, and no physical law.

Logical consistency alone does not guarantee physical realizability. Most possible worlds must fail.

The Pre-Physical Selection Principle

Existence is not assumed but selected. We introduce an existential selection functional

$$\Xi : \mathcal{W} \rightarrow \mathbb{R},$$

measuring a world's capacity to sustain coherent structure.

$$\boxed{ \Xi(W)= \alpha\,\mathcal{C}(W) + \beta\,\mathcal{S}(W) + \gamma\,\mathcal{G}(W) - \delta\,\mathcal{D}(W) }$$

The realized world is

$$\boxed{ W^{\ast} = \arg\max_{W\in\mathcal{W}} \Xi(W). }$$

Worlds that generically destroy information or generate absolute singularities are excluded prior to physics.

From Selection to Physical Emergence

Physics is not fundamental. It emerges only within worlds selected by $\Xi$.

The primary physical quantity is not energy or matter, but an informational field

$$\boxed{ I(x,t) = \text{coherent informational density}. }$$

Fundamental Dynamical Equation

The evolution of $I$ is governed by

$$\boxed{ \partial_t I = \nabla\!\cdot\!\big(D(I,t)\nabla I\big) + \alpha I - \beta I^3 + \eta(x,t). }$$

This equation generates structure while preventing divergence. Spacetime, locality, and dynamics arise as effective descriptions.

Emergence of Space and Time

Space emerges from stabilized local propagation of information. Time emerges as ordered convergence toward stable configurations. Neither exists prior to dynamics.

Emergent Gravity

Define the informational potential

$$\boxed{ \Phi = -\log I. }$$

Motion follows

$$\boxed{ \ddot{x} = -\nabla \Phi. }$$

Gravity is an informational gradient. Mass corresponds to localized coherence. The equivalence principle emerges structurally.

Dark Matter as an Informational Phase

Dark matter is not particulate. It corresponds to non-localized regions of elevated $I$ that gravitate but do not support stable excitations.

Galactic rotation curves and the Radial Acceleration Relation arise naturally, with a universal acceleration scale $a_{\ast}$ emerging dynamically.

Dark Energy as Structural Continuity

Dark energy reflects a global mechanism preventing informational saturation. Large-scale redistribution of coherence manifests as accelerated expansion.

An effective equation of state $w\approx -1$ arises without vacuum energy. The small but non-zero value of $\Lambda$ reflects near-critical structural balance.

Black Holes and Conditional Singularities

When

$$I > I_{\rm crit},$$

information propagation ceases ($D\to0$). Locality and time fail.

This is a conditional singularity: spacetime ends, but information does not. Absolute singularities are forbidden by selection.

Information Preservation

Information is not destroyed or transferred to other dimensions. It loses spacetime representation but persists as relational structure within the generative framework.

This resolves the black-hole information paradox without exotic assumptions.

Numerical Implementation

The theory is implemented numerically using lattice and network discretizations. Parameters are selected by maximizing $\Xi$. Simulations exhibit entropy saturation, emergence of locality, stable cores, and absence of runaway collapse.

Observational Tests

SPARC Galaxies

Analysis of SPARC rotation curves yields

$$a_{\ast} \approx 9.4\times10^{-11}\,\mathrm{m\,s^{-2}},$$

emerging directly from data without tuning.

Gravitational-Wave Ringdown

Horizon-scale informational suppression predicts small deviations in quasinormal modes:

$$\omega_n = \omega_n^{\rm GR} \left[1-\epsilon \exp\!\left(-\left(\frac{a_{\ast}}{a_{\rm hor}}\right)^p\right)\right].$$

These deviations are testable with next-generation detectors.

Falsifiability

The theory is falsified if:

• no universal acceleration scale exists,
• ringdown deviations are absent at predicted sensitivity,
• simulations generically produce absolute singularities.

Conceptual Implications

Physical laws are emergent regularities, not axioms. Existence is a selected outcome. Information is the ontological substrate from which physics arises.

Conclusion

This framework explains why this universe exists, why it is stable, and why its dark phenomena arise. It unifies gravity, cosmology, and information within a single generative logic.

If confirmed, physics must be reinterpreted as the study of selected regularities, not fundamental laws.
