  1. Divergent Perspectives on Expert Disagreement: Preliminary Evidence From Climate Science, Climate Policy, Astrophysics, and Public Opinion.James R. Beebe, Maria Baghramian, Luke Drury & Finnur Dellsén - 2019 - Environmental Communication 13:35-50.
    We report the results of an exploratory study that examines the judgments of climate scientists, climate policy experts, astrophysicists, and non-experts (N = 3367) about the factors that contribute to the creation and persistence of disagreement within climate science and astrophysics and about how one should respond to expert disagreement. We found that, as compared to non-experts, climate experts believe that within climate science (i) there is less disagreement about climate change, (ii) methodological factors play less of a role (...)

  2. Dark Matters in Contemporary Astrophysics: A Case Study in Theory Choice and Evidential Reasoning.William L. Vanderburgh - 2001 - Dissertation, The University of Western Ontario (Canada)
    This dissertation examines the dynamical dark matter problem in twentieth century astrophysics from the point of view of History and Philosophy of Science. The dynamical dark matter problem describes the situation astronomers find themselves in with regard to the dynamics of large scale astrophysical systems such as galaxies and galaxy clusters: The observed motions are incompatible with the visible distribution matter given the accepted law of gravitation. This discrepancy has two classes of possible solutions: either there exists copious amounts (...)

    Transforms for the Early Kerr Metric.Stephen Athel Abbott - manuscript
    The concept and usage of the word 'metric' within General Relativity is briefly described. The early work of Roy Kerr led to his original 1963 algebraic, rotating metric. This discovery and his subsequent recollection in 2008 are summarised as the motivation for this article. Computer algebra has confirmed that nominal transformations of this early metric can generate further natural algebraic metrics. The algebra is not abstract, nor advanced, and these metrics have been overlooked for many years. The 1916 metric due (...)

  6. On the Limits of Experimental Knowledge.Peter Evans & Karim P. Y. Thebault - 2020 - Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences 378 (2177).
    To demarcate the limits of experimental knowledge, we probe the limits of what might be called an experiment. By appeal to examples of scientific practice from astrophysics and analogue gravity, we demonstrate that the reliability of knowledge regarding certain phenomena gained from an experiment is not circumscribed by the manipulability or accessibility of the target phenomena. Rather, the limits of experimental knowledge are set by the extent to which strategies for what we call ‘inductive triangulation’ are available: that is, (...)

  7. Data models, representation and adequacy-for-purpose.Alisa Bokulich & Wendy Parker - 2021 - European Journal for Philosophy of Science 11 (1):1-26.
    We critically engage two traditional views of scientific data and outline a novel philosophical view that we call the pragmatic-representational view of data. On the PR view, data are representations that are the product of a process of inquiry, and they should be evaluated in terms of their adequacy or fitness for particular purposes. Some important implications of the PR view for data assessment, related to misrepresentation, context-sensitivity, and complementary use, are highlighted. The PR view provides insight into the common (...)

    Space, Time, and Irreversibility.Gustavo E. Romero - 2017 - MÈTODE Science Studies Journal 7:201-209.
    Scientific philosophy is that which is informed by science. It uses exact tools such as logic and mathematics and provides a framework for scientific activity to solve more general questions about nature, the language we use to describe it, and the knowledge we obtain thanks to it. Many of the scientific philosophy theories can be proven and evaluated using scientific evidence. In this paper, I focus on showing how several classical philosophy topics, such as the nature of space and time (...)

  9. Human/Humanity, Consciousness and Universe: Informational Relation.Florin Gaiseanu - 2019 - Neuroquantology 17 (5):20-30.
    From the perspective of the Informational Model of Consciousness elaborated and reported recently on the basis of the last discoveries of the quantum mechanics and astrophysics, the meeting horizon between some ancient coherent empirical models of the humanity and our modern scientific results is analyzed. These results are discussed in terms of information, as a central axis relating the universe, the human and inter-humanity connections, and consciousness as an informational tool for the exploration of the reality. Bringing into discussion (...)

Based on recent discoveries of quantum physics and astrophysics, revealing a new understanding of our environment (...)

  11. Is Simulation a Substitute for Experimentation?Isabelle Peschard - manuscript
    It is sometimes said that simulation can serve as epistemic substitute for experimentation. Such a claim might be suggested by the fast-spreading use of computer simulation to investigate phenomena not accessible to experimentation (in astrophysics, ecology, economics, climatology, etc.). But what does that mean? The paper starts with a clarification of the terms of the issue and then focuses on two powerful arguments for the view that simulation and experimentation are ‘epistemically on a par’. One is based on the (...)

    A Multi-Wavelength Data Analysis with Multi-Mission Space Telescopes.Yang I. Pachankis - 2022 - International Journal of Innovative Science and Research Technology 7 (1):701-708.
    The article summarizes the software tool on astrophysical analysis with multi-wavelength space telescope data. It recaps the evidence analysis conducted on the Kerr-Newman black hole (KNBH). It was written prior to the article Research on the Kerr-Newman Black Hole in M82 Confirms Black Hole and White Hole Juxtapose not soon after the experiment. The conducted analysis suggested Hawking radiation is caused by the movement of ergosurfaces of the BH and serves as the primal evidence for black hole and white hole (...)

  13. On Natural Selection and Hume's Second Problem.Armando Aranda-Anzaldo - 1998 - Evolution and Cognition 4 (2):156-172.
    David Hume's famous riddle of induction implies a second problem related to the question of whether the laws and principles of nature might change in the course of time. Claims have been made that modern developments in physics and astrophysics corroborate the translational invariance of the laws of physics in time. However, the appearance of a new general principle of nature, which might not be derivable from the known laws of physics, or that might actually be a non-physical one (...)

    Poetry, Science and Revolution: The Enigma of Herman Gorter’s Pan.Hub Zwart - 2019 - Journal of Dutch Literature 10 (1):24-49.
    Herman Gorter (1864-1927) became famous as the author of May (1889) and Poems (1890). His opus magnum Pan, published in 1916, hardly acquired any readership at all, which is remarkable, given the monumental size and scope of this unique achievement, celebrating the imminent proletarian revolution and the advent of the communist era: a visionary work of global proportions. Gorter’s Pan will be assessed as thinking poetry, more precisely: as dialectical materialist poetry, as a work of art which articulates a dialectical (...)

    Evil Twins and the Multiverse: Distinguishing the World of Difference Between Epistemic and Physical Possibility.Mark Satta - 2019 - Synthese 198 (2):1153-1160.
    Physicists Brian Greene and Max Tegmark both make variants of the claim that if the universe is infinite and matter is roughly uniformly distributed, then there are infinitely many “people with the same appearance, name and memories as you, who play out every possible permutation of your life choices.” In this paper I argue that--while our current best theories in astrophysics may allow one to conclude that we have infinitely many duplicates whose lives are identical to our own from (...)

    Gravitational Singularities.Nicolae Sfetcu - manuscript
    Gravitational singularities in general relativity are spacetime locations where the gravitational field becomes infinite. Scalar invariant curves of spacetime include a measure of matter density. Some physicists and philosophers believe that because the density of matter tends to become infinite in singularity, spacetime laws are no longer valid there. A gravitational singularity almost universally accepted in astrophysics and cosmology as the earliest state of the universe, is the Big Bang. In this case also, the known laws of physics are (...)

    Tests and Anomalies of Post-Newtonian Gravitational Theories.Nicolae Sfetcu - manuscript
    Usually, the "laboratory" of gravitational tests was the celestial bodies, the astrophysical systems. But such tests are disturbed by non-gravitational effects. The most used such "laboratory" was the solar system. Recently, scientists have focused on observing binary pulsars for the verification of gravitational theories, by observing the variations of the orbital period, thus providing indirect evidence for the emission of gravitational radiation. But the experimenter cannot "arrange the lab" according to his needs, nor trigger certain events when he needs them. (...)

    A Wormhole of Light by Using Electronic Materials.Areena Bhatti - 2020 - Physics Tomorrow Letters 2:9.
    Wormhole is a popular tool for interstellar travel in science fiction. It connects two different space-time points directly although such an astrophysical object is not yet observed, but in 2015, researchers in Spain created a tiny magnetic wormhole for the first time ever. They used it to connect two regions of space so that a magnetic field could travel 'invisibly' between them. This article presents a model of making a wormhole of light on the principle of conversion of energy so (...)

    Universal Consciousness.Alexis Karpouzos - 2016 - Athens, Greece: COSMIC SPIRIT.
    The central teaching of mysticism is that Everything is One, whereas from the side of rationalism the universe is Multiple. The essence of the mystical tradition is not a particular philosophical system, but the simple realization that the soul of any individual/existence is identified with the Absolute. A special feature of the mysticism is the elimination of discriminations, i.e. the One and the Multiple are identical.On the other hand, in rationalism the One and the Multiple differ substantially. Mysticism aims at (...)
