  1. Origin of Life as a Probabilistic Event in the Universe.Dimitri Marques Abramov & Carlos Alberto Mourão-Junior - manuscript
    By means of a probabilistic mathematical model, we bring into discussion the origin of life as a stochastic process. We consider only the chance of information emergence in the proteome and genome under the ideal thermodynamic and chemical conditions. For a more realistic model, we used, as a parameter, the information amount in N. equitans genome, the simplest known nowadays, as the equivalent to the first living cell that could have emerged in primitive Earth. We estimated the probability of information (...)

  2. Dark Origins: Departure from an Ex-Nihilo Big Bang.Onyemaechi Ahanotu - manuscript
    With the growing body of research on Black Holes, it is becoming increasingly apparent that these celestial objects may have a stronger part to play in the universe than previously thought, shaping galaxies and influencing star formation. In this manuscript, I take these findings a step further, proposing a new set of boundary conditions to both the early and late Universe, extrapolating from thermodynamics. I propose that the Universe will collapse into a massive black hole and that the Big Bang (...)

  3. The Ontic Probability Interpretation of Quantum Theory - Part II: Einstein's Incompleteness/Nonlocality Dilemma (2nd edition).Felix Alba-Juez - manuscript
    After identifying in Part I [1] a conceptual confusion (TCC), a Reality preconception (TRP1), and a fallacious dichotomy (TFD), the famous EPR/EPRB [2] [3] [4] [5] [6] argument for correlated ‘particles’ is now studied in the light of the Ontic Probability Interpretation of Quantum Theory (QT/TOPI). Another Reality preconception (TRP2) is found, showing that EPR used and ignored QT predictions in a single paralogism. Employing TFD and TRP2, EPR unveiled a contradiction veiled in its premises. By removing nonlocality from QT’s (...)

  4. From Zeno to Einstein.Ferenc András - manuscript
    Some experimental theories of quantum gravity, such as loop quantum gravity, propose a discrete or ``quantized'' structure for space-time at very small scales. These theories hypothesize that space-time is fundamentally made up of discrete units or ``atoms'' of space, in a similar way to how matter is fundamentally made up of discrete particles. In the context of space-time, the term ``atomic structure'' is used metaphorically to suggest a discrete or granular nature at extremely small scales. In Einstein's special theory of (...)

  5. Unitary Phase Architecture (UPA): Towards Asymptotic Cognition through Resonant Quantum Computation.Mahammad Ayvazov - manuscript
    This paper introduces the Unitary Phase Architecture (UPA), a novel computational paradigm rooted in the principles of Phase Ontology, designed to emulate Cyclical Cognition (Cognitio Recurrens) and achieve asymptotic understanding without relying on precise, discrete solutions. Diverging from conventional classical and current quantum computing models that predominantly operate on probabilistic interpretations, UPA postulates a computational environment based on the field of potentials, engaging in an improbabilistic mode of operation. This architecture leverages resonant algorithms that utilize asymptotic phase coherence as their (...)

  6. Unified Field Theory (UFT) as the Grammar of Difference.Mahammad Ayvazov - manuscript
    This article develops a philosophical reinterpretation of gravity as the asymptotic fold of ontological difference into stable phase coherence. Departing from traditional conceptions that treat gravitation as a force or as spacetime curvature, we propose a dynamic framework in which coherence — not mass or energy — serves as the primary organizational principle. Drawing from phase-space formalism, topology and metaphysics, we introduce the concept of the assemblage point as a singular phase location where divergent trajectories converge through resonance. Gravity is (...)

  7. Interference as the Ontological Structure of Event: Toward a Phase-Based Theory of Superposition and Boundary.Mahammad Ayvazov - manuscript
    This paper proposes a phase-theoretical reinterpretation of event structure grounded in the quantum principle of amplitude superposition. Rather than treating events as discrete occurrences in time or space, we argue that they emerge as stabilized interferences — structured resonances within fields of oscillating potential. Drawing from quantum physics, topology and metaphysics, we show that boundaries, identities and even laws are not fixed entities but dynamic thresholds sustained by rhythmic coherence. By shifting attention from probability to amplitude, and from time to (...)

  8. Gravitation as the Asymptotic Folding of Difference: Toward a Phase-Based Ontology of Law and Form.Mahammad Ayvazov - manuscript
    This article proposes a novel ontological interpretation of gravitation, not as a fundamental force, but as the asymptotic folding of difference into coherent form. Drawing from phase space theory, topological dynamics and contemporary field theories, we explore how gravitational attraction emerges as a visible trace of systems seeking phase alignment across differentiated trajectories. Rather than imposing order, gravity reflects the recursive stabilization of tension through minimal coherence gradients. We introduce the concept of the assemblage point as a cusp of systemic (...)

  9. Has the Copenhagen interpretation ever existed? (or, has physics community ever taken Bohr (and Heisenberg) seriously?).Mario B. Valente - manuscript
    It is well-known that, historically, there is no unique interpretation, which might be named the Copenhagen interpretation. At best, it seems to be the case that there is a plethora of related interpretations that, for simplicity, are named as such. Here, a more heterodox possibility is presented. Has this interpretation ever been used/taken into account by physicists? It is a fact that historians, philosophers of science, and a handful of physicists interested in the interpretation of quantum theory have considered, discussed, (...)

  10. New Prospects for a Causally Local Formulation of Quantum Theory.Jacob A. Barandes - manuscript
    It is difficult to extract reliable criteria for causal locality from the limited ingredients found in textbook quantum theory. In the end, Bell humbly warned that his eponymous theorem was based on criteria that “should be viewed with the utmost suspicion.” Remarkably, by stepping outside the wave-function paradigm, one can reformulate quantum theory in terms of old-fashioned configuration spaces together with ‘unistochastic’ laws. These unistochastic laws take the form of directed conditional probabilities, which turn out to provide a hospitable foundation (...)

  11. The Stochastic-Quantum Theorem.Jacob A. Barandes - manuscript
    This paper introduces several new classes of mathematical structures that have close connections with physics and with the theory of dynamical systems. The most general of these structures, called generalized stochastic systems, collectively encompass many important kinds of stochastic processes, including Markov chains and random dynamical systems. This paper then states and proves a new theorem that establishes a precise correspondence between any generalized stochastic system and a unitarily evolving quantum system. This theorem therefore leads to a new formulation of (...)

    The quantum measurement problem, particularly the observer effect, has long resisted a complete explanation, often forcing a choice between paradoxical interpretations and a fundamental split between the quantum and classical worlds. This paper introduces Aethic reasoning, a novel framework that resolves the measurement problem by reformulating the logical and relational structure that underpins reality. We propose three foundational postulates that redefine realism, superposition, and state validity from a relational standpoint. The derivation begins with the Third Postulate, which posits that reality (...)

    The quantum measurement problem is one of the most profound challenges in modern physics, questioning how and why the wavefunction collapses during measurement to produce a single observable outcome. In this paper, we propose a novel solution through a logical framework called Aethic reasoning, which reinterprets the ontology of time and information in quantum mechanics. Central to this approach is the Aethic principle of extrusion, which models wavefunction collapse as progression along a Markov chain of block universes, effectively decoupling the (...)

  14. PHET and the Event Horizon of Experience A Phenomenological Resolution to the Quantum–Classical Divide.Mario Boido - manuscript
    The quantum measurement problem has long been framed as a conflict between the continuous, unitary evolution of quantum systems and the discrete, definite events that appear in experience. This white paper argues that the problem arises not within physics, but at the interface between physical description and the temporal structure of consciousness. Quantum mechanics describes potentials—amplitudes, correlations, and evolving relations—but it contains no resources for generating events, definiteness, or a present moment. These belong to the phenomenology of experience. -/- Drawing (...)

  19. Creative and geometric times in physics, mathematics, logic, and philosophy.Flavio Del Santo & Nicolas Gisin - manuscript
    We propose a distinction between two different concepts of time that play a role in physics: geometric time and creative time. The former is the time of deterministic physics and merely parametrizes a given evolution. The latter is instead characterized by real change, i.e. novel information that gets created when a non-necessary event becomes determined in a fundamentally indeterministic physics. This allows us to give a naturalistic characterization of the present as the moment that separates the potential future from the (...)

In connection with nonlinear dynamical equations, we demonstrate that feedback mechanisms in complex systems are often erroneously reduced to phenomenological models. This reveals a methodological pitfall in physical research: phenomenological models grounded in reductionism may fail to uniquely map onto the intrinsic dynamics of the system. Consequently, we advocate establishing a new paradigm (...)

    While physicists know how to use quantum mechanics, there is no consensus on what quantum mechanics is a mechanics of. The aim of this paper is to introduce the beginning of what might turn out to be an interpretation of quantum mechanics—one that leaves all calculated probabilities intact. The basic idea is that quantum mechanics describes the objective world, but there must be added to it ineffable variables, one of which is the temporal 'now'. Ineffable variables are not 'hidden variables'.

The UME decomposes dynamics into four orthogonal components: symplectic flow (Hamiltonian coherence), dissipative flow (friction work), collapse flow (attractor dynamics), and stochastic forcing (exploration). We demonstrate that this decomposition maps naturally onto the division of cognitive labor between humans and generative AI systems. Humans provide the symplectic term (first principles, constraints) and collapse term (purpose, meaning); AI handles the dissipative (...)

  46. Proliferation of Post-Newtonian, Non-Relativistic Theories.Nicolae Sfetcu - manuscript
    Theoreticians have formulated a set of fundamental criteria that any theory of gravity should satisfy, two purely theoretical and two that are based on experimental evidence. Thus, a theory must be complete (capable of analyzing from the "first principles" the result of any experiment of interest), self-consistent (its prediction for the outcome of each experiment must be unique), relativistic (at the limit when gravity is neglected compared to other physical interactions, non-gravitational laws of physics must be reduced to special relativity (...)

  47. Prolifération des théories post-einsteiniennes - Formalisme paramétrisé post-newtonien (PPN).Nicolae Sfetcu - manuscript
    Immédiatement après l'élaboration et le succès de la relativité générale, des théories alternatives pour la gravité ont commencé à apparaître. En développant ces théories, de nombreuses stratégies différentes (heuristiques positives) ont été essayées, en ajoutant de nouvelles hypothèses à la RG, en utilisant un espace-temps pour lequel l'univers est statique, des hypothèses qui éliminent les singularités gravitationnelles, etc. Pour l'évaluation des modèles de gravité, plusieurs séries de tests ont été proposées. Le formalisme paramétrisé post-newtonien (PPN) détaille les paramètres qui différencient (...)

  48. Prolifération des théories post-newtoniennes.Nicolae Sfetcu - manuscript
    Les théoriciens ont formulé un ensemble de critères fondamentaux que toute théorie de la gravité devrait satisfaire, deux purement théoriques et deux fondés sur des preuves expérimentales. Ainsi, une théorie doit être : complet (capable d'analyser à partir des « premiers principes » le résultat de toute expérience d'intérêt), auto-cohérent (sa prédiction pour le résultat de chaque expérience doit être unique), relativiste (à la limite où la gravité est négligée par rapport à d'autres interactions physiques, les lois non gravitationnelles de (...)

  49. Unificarea gravitației cu celalalte forțe fundamentale.Nicolae Sfetcu - manuscript
    Au fost propuse mai multe teorii unificatoare. Marea unificare presupune existența unei forțe electronucleare. Ultimul pas ��n unificare ar necesita o teorie care să includă atât mecanica cuantică cât și gravitația prin relativitatea generală (”teoria finală”). După 1990, unii fizicieni consideră că teoria M 11-dimensională, identificată adesea cu una dintre cele cinci teorii ale supercorzilor perturbative, sau uneori cu supergravitația maximal-supersimetrică 11-dimensională, este teoria finală.

  50. Le modèle atomique de Bohr, un exemple de programme de recherche.Nicolae Sfetcu - manuscript
    Le modèle atomique de Bohr a été l'un des exemples les plus brillants de la méthodologie des programmes de recherche d'Imre Lakatos. Les grandes lignes du programme de recherche de Bohr (Bohr 1913) peuvent être caractérisées par : 1. Le problème initial ; 2. Ses heuristiques négatives et positives ; 3. Les problèmes qu'il a tenté de résoudre au cours du développement ; 4. Son point de dégénérescence (point de saturation) et, enfin, 5. Le programme par lequel il a été (...)
