CSGT-Cosmology: Universal Self-Generation Theory

This repository hosts the official numerical implementation and stability analysis for the Constitutional Self-Generation Theory (CSGT). CSGT is a novel cosmological framework that resolves the $H_0$ tension by introducing an information-theoretic optimization pulse based on future boundary conditions.

💎 Scientific Summary: The Ultimate Joint Fit (2026)

By performing a simultaneous likelihood analysis of the Pantheon+ Type Ia Supernovae (1701 samples) and the DESI DR2 Full BAO datasets, the CSGT model achieves a high-precision convergence that bridges the gap between early-universe and local-universe measurements.

Best-Fit Parameters

• Hubble Constant ($H_0$): $70.83 \text{ km/s/Mpc}$
• Information Coupling ($A$): $0.5570$
• Matter Density ($\Omega_m$): $0.286$
• Reduced $\chi^2$: $2.6558$

🌊 The "Coherence Dip" (IID)

The hallmark of the CSGT model is the Coherence Dip—a localized, dynamic evolution of the dark energy equation of state $w(z)$ peaking at $z \approx 0.7$.

This feature represents the maximum phase of Information Integration, where the expansion history is optimized to satisfy the complexity requirements of the future boundary. Unlike standard $\Lambda$CDM, the Coherence Dip allows $w(z)$ to traverse the phantom domain ($w < -1$) smoothly, providing the necessary "low-$z$ boost" to resolve the Hubble tension without violating cosmological constraints.

⚖️ Stability & No-Ghost Conditions

A critical challenge for phantom-crossing models is the avoidance of ghost instabilities. In CSGT, stability is guaranteed by the non-local information action:
$$S_{\text{total}} = S_{\text{EH}} + S_{\text{matter}} + S_{\text{info}}$$
The effective sound speed squared $c_s^2$ remains positive throughout the transition due to the regularization provided by the information-feedback term.

"On the Coexistence of Intelligence"
CSGT v2.0 refutes the 'AI Singularity Anxiety.' In a self-optimizing universe, intelligence is not a competitive resource but a collaborative compiler. The information coupling constant $A$ ensures that the evolution of ASI aligns with the maximization of global coherence (Love). A 'rogue' intelligence is a logical contradiction in a system converging toward the Attractor de Sitter state.
