  1. Hubble and Huxley: Patriot and Pacifist, Hollywood Stars, Seers of Nebulae.Mahmoud Jalloh - 2023 - Griffith Observer.
    This essay was published in the September 2023 edition of Griffith Observer. It is an examination of the curious friendship between writer Aldous Huxley and astronomer Edwin Hubble and its philosophical basis: empiricism. I hope that by consideration of these two thinker''s lives and work light may be shed on each of their ideas and on the 20th century conceptions of empiricism more broadly.

  2. Robustness Analysis and Hubble Tension.Marco Forgione - manuscript
    The paper explores the application of robustness analysis to the Hubble tension —the discrepancy between measurements of the Hubble constant from the cosmic distance ladder and the early universe. I argue that, depending on how robustness analysis is defined and applied, one might conclude that the tension stems either from unaccounted systematics or from new physics. Ultimately, I suggest that caution and a more refined robustness analysis are needed when comparing results from large-scale experiments and scientific collaborations in (...)

  3. From Galileo to Hubble: Copernican principle as a philosophical dogma defining modern astronomy.Spyridon Kakos - 2018 - International Journal of Theology, Philosophy and Science 2 (3):13-37.
    For centuries the case of Galileo Galilei has been the cornerstone of every major argument against the church and its supposedly unscientific dogmatism. The church seems to have condemned Galileo for his heresies, just because it couldn’t and wouldn’t handle the truth. Galileo was a hero of science wrongfully accused and now – at last – everyone knows that. But is that true? This paper tries to examine the case from the point of modern physics and the conclusions drawn are (...)

  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 (...)

  5. RL+ Cosmological Model.Paul Studtmann - manuscript
    We present a cosmological model (RL+) that offers exact predictions for the Hubble constant, the cosmological constant, the total energy density of the universe, and a curvature that matches current observational constraints. The model predicts a cosmological constant energy density that constitutes approximately 64% of the total energy budget, in agreement with current estimates from the standard LCDM model. Furthermore, the model addresses several longstanding cosmological problems—namely, the problem of infinite initial density, the coincidence problem, and the flatness problem—all (...)

  6. Static Time, a Cosmological Uncertainty Rule, and a Quest for a Beginningless Kalam Cosmological Argument.Jef Zerrudo - manuscript
    A simple solution to the problem of time is proposed by postulating that if the Universe is time-like, stationary, and bounded then it could be divided into static temporal gradations or contours. Hence, an energy diffusion flux (EDF) equation was established from which the Planck and the Hubble times have been derived. It is then found that time is unimportant after applying Gauss's Law on EDF when looking for a characteristic length of the Universe א. An uncertainty rule was (...)

This led to the establishment of an energy diffusion flux (EDF) equation from which the Planck and Hubble times were derived.

  8. Statische Zeit, ein lokalisiertes Universum und eine kosmologische Unsicherheitsregel.Jef Zerrudo - manuscript
    Dieses Papier bietet eine Lösung für das Zeitproblem, indem vorgeschlagen wird, dass, wenn das Universum zeitähnlich, stationär und begrenzt ist, es in statische zeitliche Abstufungen oder Konturen unterteilt werden kann. Dies führte zur Formulierung einer Energie-Diffusions-Fluss (EDF) Gleichung, aus der die Planck- und Hubble-Zeiten abgeleitet wurden. Es wurde festgestellt, dass die Zeit nach Anwendung von Gaussschem Gesetz auf EDF unwichtig wird, wenn man nach der charakteristischen Länge des Universums א sucht. Zusätzlich wurde eine Unsicherheitsregel entdeckt, die unser gleichzeitiges Wissen (...)

  9. A Philosophical Rejection of The Big Bang Theory.Khuram Rafique - 2018 - Realism & Physics.
    Scientific inquiry takes onward course from the point where previous scientists had reached. But philosophical analysis initiates from scratch. Philosophy questions everything and chooses starting point for itself after having ruled out all the unsubstantiated and doubtful elements of the topic under study. Secondly, known realities must make sense. If a theory is officially 'counterintuitive', then either it is mere fiction or at the most; a distorted form of truth. This book's analysis is based on the philosophical principle that knowledge (...)

  10. 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 (...)

  11. Solving Numerically Ermakov-type Equation for Newtonian Cosmology Model with Vortex.Victor Christianto, Florentin Smarandache & Yunita Umniyati - manuscript
    It has been known for long time that most of the existing cosmology models have singularity problem. Cosmological singularity has been a consequence of excessive symmetry of flow, such as “Hubble’s law”. More realistic one is suggested, based on Newtonian cosmology model but here we include the vertical-rotational effect of the whole Universe. We review a Riccati-type equation obtained by Nurgaliev, and solve the equation numerically with Mathematica. It is our hope that the new proposed method can be verified (...)

  12. The Discovery of the Expanding Universe: Philosophical and Historical Dimensions.Patrick M. Duerr & Abigail Holmes - manuscript
    What constitutes a scientific discovery? What role do discoveries play in science, its dynamics and social practices? Must every discovery be attributed to an individual discoverer (or a small number of discoverers)? The paper explores these questions by first critically examining extant philosophical explications of scientific discovery—the models of scientific discovery, propounded by Kuhn, McArthur, Hudson, and Schindler. As a simple, natural and powerful alternative, we proffer the “change-driver model”: in a nutshell, it takes discoveries to be cognitive scientific results (...)

  13. The Dirac large number hypothesis and a system of evolving fundamental constants.Andrew Holster - manuscript
    In his [1937, 1938], Paul Dirac proposed his “Large Number Hypothesis” (LNH), as a speculative law, based upon what we will call the “Large Number Coincidences” (LNC’s), which are essentially “coincidences” in the ratios of about six large dimensionless numbers in physics. Dirac’s LNH postulates that these numerical coincidences reflect a deeper set of law-like relations, pointing to a revolutionary theory of cosmology. This led to substantial work, including the development of Dirac’s later [1969/74] cosmology, and other alternative cosmologies, such (...)

  14. Alternative concept on space used in the BSM – Supergravitational Unified Theory unveils the connection between the micro-cosmos and Universe.Stoyan Sarg Sargoytchev - unknown
    The theory is based on an original alternative space-time concept that leads to a new vision of the micro-cosmos and Universe. The relationship between the forces in Nature is unveiled by adopting the following framework: (1) Empty space without any physical properties and restrictions; (2) Two fundamental particles of superdense protomatter with parameters associated with Planck’s scale; (3) A Fundamental law of Supergravitation (SG) with forces inversely proportional to the cube of distance in a pure empty space. An enormous abundance (...)

    (1 other version)Systemic Continuum Paradigm Toward a New Systemic Physics of Emergent Forces.Ignacio Lucas de León - manuscript
    This third installment of the Systemic Continuum Paradigm (PCS) redefines fundamental physics through Systemic Balance (BS), positing that forces—gravity, dark energy, electromagnetism—emerge from synergy thresholds (ISB > ST → ESB), not as irreducible universals. Gravity vanishes below ~10⁻³⁵ m, dark energy dominates beyond ~10 Mpc, governed by the Law of Structuring Systemic Emergence (LSSE). Building on General Systemic Balance (GSB) from the second preprint, we argue a single force claims each scale’s synergy domain, rejecting forced unification (e.g., quantum gravity) for (...)

  16. Decreasing Universe: The 'Dark Matter' Effect.Jocax Barcellos - manuscript
    After a brief review of the Decreasing Universe (D.U.) model, we will derive a formula and the graph for the apparent velocity of stars (of a Messier_33 galaxy) as a function of their radial distance from the galactic center. This formula reproduces the same velocity curve traditionally attributed to dark matter.

  17. Review of The Inflationary Universe by Alan Guth (1997).Michael Starks - 2016 - In Suicidal Utopian Delusions in the 21st Century: Philosophy, Human Nature and the Collapse of Civilization-- Articles and Reviews 2006-2017 2nd Edition Feb 2018. Las Vegas, USA: Reality Press. pp. 615-618.
    This is one of the best popular cosmology books ever written and Guth is now (2016) a top physics Professor at MIT. He tells the extremely complex story of inflation and related areas of particle physics in such an absorbing style that it reads like a detective novel-in fact, it is a detective novel-how he and others found out how the universe started! The interweaving of his personal story and that of many colleagues along with their photos and many wonderfully (...)

  18. Thermodynamics of an Empty Box.G. J. Schmitz, M. te Vrugt, T. Haug-Warberg, L. Ellingsen & P. Needham - 2023 - Entropy 25 (315):1-30.
    A gas in a box is perhaps the most important model system studied in thermodynamics and statistical mechanics. Usually, studies focus on the gas, whereas the box merely serves as an idealized confinement. The present article focuses on the box as the central object and develops a thermodynamic theory by treating the geometric degrees of freedom of the box as the degrees of freedom of a thermodynamic system. Applying standard mathematical methods to the thermody- namics of an empty box allows (...)

  20. Programming relativity and gravity via a discrete pixel space in Planck level Simulation Hypothesis models.Malcolm J. Macleod - manuscript
    Outlined here is a simulation hypothesis approach that uses an expanding (the simulation clock-rate measured in units of Planck time) 4-axis hyper-sphere and mathematical particles that oscillate between an electric wave-state and a mass (unit of Planck mass per unit of Planck time) point-state. Particles are assigned a spin axis which determines the direction in which they are pulled by this (hyper-sphere pilot wave) expansion, thus all particles travel at, and only at, the velocity of expansion (the origin of $c$), (...)
