  1. ΛCDM and MOND: A debate about models or theory?Melissa Jacquart - 2021 - Studies in History and Philosophy of Science Part A 89 (C):226-234.
    The debate between ΛCDM and MOND is often cast in terms of competing gravitational theories. However, recent philosophical discussion suggests that the ΛCDM–MOND debate demonstrates the challenges of multiscale modeling in the context of cosmological scales. I extend this discussion and explore what happens when the debate is thought to be about modeling rather than about theory, offering a model-focused interpretation of the ΛCDM–MOND debate. This analysis shows how a model-focused interpretation of the debate provides a better (...)

    Decreasing Universe: AI Analysis of Article Data Disproves L-CDM Model.J. Barcellos - manuscript
    The Article ( ‘Decreasing Universe: redshifts and distance data refute the LCDM model’[01]) and the data inside it was analized by some Artificial Inteligence.

  3. Decreasing Universe: redshifts and distance data refute the L-CDM model.Jocax Barcellos - manuscript
    To evaluate and compare the “Decreasing Universe theory” with the LCDM model, I created a potentially falsifiable prediction and the data was extracted and analyzed.

  4. Trouble with Hubble: Status of the Big Bang Models.Chris Smeenk - 2022 - Philosophy of Science 89 (5):1265-1274.
    Cosmologists take the $\Lambda$CDM model to be a permanent contribution to our knowledge of the universe, based on the success of precision cosmology. Consistent, independent determinations of the parameters in this model encourage physicists to take it seriously. This stance incurs an obligation to resolve any discrepancies by reanalyzing measurements or adding further complexity. Recent observations in cosmology indicate a tension between “local” and “global” determinations of the Hubble constant. Here I argue that this tension illustrates one of the benefits (...)

  5. Thinking Out Loud on Early Creation through the Lens of Hermeneutics of Sherlock Holmes (Towards a Model of Universe based on Turbulence-Generated Sound Theory).Victor Christianto & Florentin Smarandache - manuscript
    In recent years, apparently the Big Bang as described by the Lambda CDM-Standard Model Cosmology has become widely accepted by majority of physics and cosmology communities. Even some people have concluded that it has no serious alternative in horizon. Is that true? First, as we argued elsewhere, Big Bang story relies on singularity. In other words, when we are able to describe the observed data without invoking singularity, then Big Bang model is no longer required. Therefore, here we explore a (...)

  6. Reinterpreting Relativity: Using the Equivalence Principle to Explain Away Cosmological Anomalies.Marcus Arvan - manuscript
    According to the standard interpretation of Einstein’s field equations, gravity consists of mass-energy curving spacetime, and an additional physical force or entity—denoted by Λ (the ‘cosmological constant’)—is responsible for the Universe’s metric-expansion. Although General Relativity’s direct predictions have been systematically confirmed, the dominant cosmological model thought to follow from it—the ΛCDM (Lambda cold dark matter) model of the Universe’s history and composition—faces considerable challenges, including various observational anomalies and experimental failures to detect dark matter, dark energy, or inflation-field candidates. (...)

  7. Comparing Cosmological Models.Andrew Holster - manuscript
    The standard model of cosmology is acclaimed in physics as accurate, robust, well-tested, our best scientific theory of the cosmos, but it has had serious anomalies for a while, including the Hubble tension, anomalous galaxies, and the completely unexplained nature of dark energy and dark matter. And lurking behind it all is the lack of a unified theory: General Relativity (GR) and quantum mechanics (QM) are inconsistent. Now startling new observations by the James Webb Space Telescope (JWST) in 2022 of (...)

    CODES_ The Last Theory of Everything.Devin Bostick - manuscript
    Version 20 (Updated April 1, 2025 — Expanded structured resonance formalism across Sections 13–15, including coherence field tensors, spiral-phase geometry, and the integration of ethics, AI cognition, mass-energy behavior, and cosmological dynamics. This version formally establishes CODES as a deterministic, mathematically unified alternative to stochastic physics, resolving emergence through chirality-driven coherence rather than probabilistic inference.) -/- ⸻ -/- Abstract -/- CODES (Chirality of Dynamic Emergent Systems) presents a unified framework that dissolves the false separation between quantum mechanics and general relativity (...)

    Fractal Bindu (S3) of Reality: The Golden Ratio as the Principle of Perfection and Harmony in Interdependent Existence.Andrei Preece & Boris Batenin - manuscript
    The wave function: ψuniverse(t) in the Fractal Bindu (S3) of Reality offers a paradigm shift in our understanding of cosmology. Unlike ΛCDM, which relies on empirically fitted parameters, this model emerges from a single, mathematically coherent framework: a compact, three-dimensional sphere (S³) where energy, space, and time evolve through fractal self-organization. -/- Rooted in the golden ratio ϕ≈1.618\phi \approx 1.618ϕ≈1.618 this theory replaces arbitrary cosmological constants with a natural, recursive structure that predicts the evolution of energy density without dark (...)

  10. Tests and Problems of the Standard Model in Cosmology.Martín López-Corredoira - 2017 - Foundations of Physics 47 (6):711-768.
    The main foundations of the standard \CDM model of cosmology are that: the redshifts of the galaxies are due to the expansion of the Universe plus peculiar motions; the cosmic microwave background radiation and its anisotropies derive from the high energy primordial Universe when matter and radiation became decoupled; the abundance pattern of the light elements is explained in terms of primordial nucleosynthesis; and the formation and evolution of galaxies can be explained only in terms of gravitation within a inflation (...)

  11. The Application of Popperian Methodology to Contemporary Cosmology.Anastasiia Lazutkina - 2021 - In Parusniková Zuzana & Merritt David, Karl Popper's Science and Philosophy. Cham, Switzerland: Springer. pp. 97-117.
    In this chapter I will discuss Karl Popper’s notion of metaphysical research programmes (MRPs) and apply it to contemporary cosmology. While Popper was extremely critical of Big Bang cosmology, his work on MRPs provides a potentially fruitful way of understanding the discipline in a different light. I will suggest that while cosmology does fail to meet the criteria Popper sets for a mature science, the standard model of cosmology (also known as ΛCDM) could be seen as an example of (...)

  13. Information Relativity Theory and its Application to Time and Space.Ramzi Suleiman - manuscript
    In a recent paper I proposed a novel relativity theory termed Information Relativity (IR). Unlike Einstein's relativity which dictates as force majeure that relativity is a true state of nature, Information Relativity assumes that relativity results from difference in information about nature between observers who are in motion relative to each other. The theory is based on two axioms: 1. the laws of physics are the same in all inertial frames of reference (Special relativity's first axiom); 2. All translations of (...)
