Part II: Cosmic Recursion: Extending Validated Recursive Dynamics to Cosmological Scales

Theoretical extension of validated recursive dynamics principles to cosmological scales. Reinterprets black holes as recursive saturation points, dark matter/energy as recursive field substrates, and cosmic evolution as self-modifying recursive processes. Addresses longstanding cosmological puzzles including black hole information paradox and fine-tuning problems through recursive framework.  Incorporates recent DESI DR2 observations showing dynamical dark energy preference (3.1-4.2σ), supporting recursive substrate interpretation. Presents specific testable predictions for CMB signatures, gravitational wave patterns, and cosmic web structure. Maintains rigorous falsification criteria while proposing paradigm-shifting reinterpretation of cosmic phenomena. Builds on convergent empirical validation across quantum, biological, neural, and climate systems documented in Part I. Provides theoretical foundation for mathematical framework developed in Part III. Version 1.3  License changed to CC-BY 4.0 to enable full scientific dissemination. No changes to content. Version 1.2 adds a significant addendum analyzing the July 2025 LIGO–Virgo–KAGRA detection of GW231123, an extreme black hole merger that challenges standard formation theories. The addendum presents this recent detection as a critical test of recursive dynamics, provides specific falsifiable predictions distinguishing the framework from General Relativity, and outlines empirical validation pathways. Main text unchanged. Version 1.1 Adds Part II to the Zenodo title.

Systems approach thresholds. Then they reorganize—or collapse. This paper formalizes saturation dynamics across scales: the core recursion equation, boundary functions, and the Recursive Saturation Index (RSI).

Saturation Thresholds in Recursive Systems: A Universal Energy Field Framework for Modeling Across Scales

This paper introduces a cross-domain modeling framework based on saturation thresholds in recursive systems. Drawing on concepts from consciousness studies, complexity science, ecology, cosmology, and artificial intelligence, it proposes a Universal Energy Field (UEF) architecture governed by the Recursive Saturation Index (RSI) and a boundary function B(Mk), defined as the ratio of internal to external recursive stress. These formal tools describe how systems evolve, stabilize, or reorganize as recursive parameters approach critical thresholds. The paper presents ten demonstrative cases — from neural integration and biological aging to climate feedbacks and early galaxy formation — illustrating how recursive saturation drives systemic reorganization. By unifying cross-scale phenomena under a recursive saturation model, this framework offers a falsifiable, interdisciplinary lens for understanding emergence, boundary shifts, and phase transitions across both physical and cognitive domains.

We are pleased to announce a second lecture from Dr. Marcello Dalmonte (ICTP) on the intricacies of statistical mechanics and phase transitions in the context of data mining the many-body problem. In this part, Marcello discusses essential concepts of the partition function, emphasizing efficient sampling strategies via Markov chains and Monte Carlo simulations. He specifically addresses the challenge of critical slowing down near phase transitions and introduces cluster algorithms as a powerful tool for effective sampling at criticality. Using the illustrative example of a three-site Ising model, Dr. Dalmonte demonstrates how temperature impacts the intrinsic dimensionality of feature spaces, providing valuable insights into many-body systems.

"All of this makes phase transitions interesting. They involve violence, universal truths and competition between rival states. The story of phase transitions is, quite literally, the song of fire and ice."
