  1. Bohmian Mechanics Without Wave Function Ontology.Albert Solé - 2013 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 44 (4):365-378.
    In this paper, I critically assess different interpretations of Bohmian mechanics that are not committed to an ontology based on the wave function being an actual physical object that inhabits configuration space. More specifically, my aim is to explore the connection between the denial of configuration space realism and another interpretive debate that is specific to Bohmian mechanics: the quantum potential versus guidance approaches. Whereas defenders of the quantum potential approach to the theory claim that Bohmian mechanics is better formulated (...)

  2. On Spacetime Functionalism.David John Baker - manuscript
    Eleanor Knox has argued that our concept of spacetime applies to whichever structure plays a certain functional role in the laws (the role of determining local inertial structure). I raise two complications for this approach. First, our spacetime concept seems to have the structure of a cluster concept, which means that Knox's inertial criteria for spacetime cannot succeed with complete generality. Second, the notion of metaphysical fundamentality may feature in the spacetime concept, in which case spacetime functionalism may be uninformative (...)

  3. The Verdict is Out: Against the Internal View of the Gauge/Gravity Duality.Eugene Chua - manuscript
    [To be presented at PSA 2018] -/- The gauge/gravity duality and its relation to the possible emergence of gravity from quantum physics has been much discussed. Recently, however, Sebastian De Haro has argued that the very notion of a duality precludes emergence, given what he calls the internal view of dualities, on which the dual theories are physically equivalent. However, I argue that De Haro's argument for the internal view is not convincing, and we do not have good reasons to (...)

    In the philosophy of time, the neo-positivist is focussed above all else on sustaining the view called the static theory of time, as the very foundation of their scientific metaphysics. This is the deeply held metaphysical conviction of almost all ‘modern philosophical-scientific’ writers on time. In fact it is hardly too much to say that the entire official modern 20th Century philosophy of physics rests on the assumption that the static theory of space-time is the only concept of time we (...)

    An imaginative exploration of space and time in which light mediates the relationship between finitude and the Infinite. Light becomes the creative source through which interiority and exteriority are manifested and brought into synchronicity as time, space and mass. The exploration probes the relational logic of relativity theory using the meta-physical insights of Augustine, Hegel, Levinas, and Peirce.

    The construction of spacetime in a physical system without time and dynamics is considered. It is shown that in models without time and dynamics anthropic principle and causality principle inevitably arise. It is shown that for any physical model based on a system without time and dynamics, the anthropic principle is a scientific principle and, in principle, can be falsified. It is shown that, in principle, there is the possibility of experimental verification of what is true - realism or idealism.

    This paper aims to address conceptual issues concerning black holes in the context of string theory, with the aim of illuminating the ontological unification of gravity and matter, and the interpretation of cosmological models. §1 describes the central concepts of the theory: the fungibility of matter and geometry, and the reduction of gravity and supergravity. The ‘standard’ interpretation presented draws on that implicit in the thinking of many (but not all) string theorists, though made more explicit and systematic than usual. (...)

    This paper introduces some basic ideas and formalism of physics in non-commutative geometry. My goals are three-fold: first to introduce the basic formal and conceptual ideas of non-commutative geometry, and second to raise and address some philosophical questions about it. Third, more generally to illuminate the point that deriving spacetime from a more fundamental theory requires discovering new modes of `physically salient' derivation.

  14. Composing Spacetime.Sam Baron & Baptiste Le Bihan - forthcoming - Journal of Philosophy.
    According to a number of approaches in theoretical physics spacetime does not exist fundamentally. Rather, spacetime exists by depending on another, more fundamental, non-spatiotemporal structure. A prevalent opinion in the literature is that this dependence should not be analysed in terms of composition. We should not say, that is, that spacetime depends on an ontology of non-spatiotemporal entities in virtue of having them as parts. But is that really right? On the contrary, we argue that a mereological approach to dependent (...)

Lam and Wüthrich have recently argued that spacetime functionalism helps to solve the epistemological problem of empirical coherence in quantum gravity and suggested that it also (dis)solves the hard problem of spacetime, namely the problem of offering a picture consistent with the emergence of spacetime from a non-spatio-temporal structure. First, I will deny that spacetime functionalism solves the hard problem by showing that it (...)

    Several different quantum gravity research programmes suggest, for various reasons, that spacetime is not part of the fundamental ontology of physics. This gives rise to the problem of empirical coherence: if fundamental physical entities do not occupy spacetime or instantiate spatiotemporal properties, how can fundamental theories concerning those entities be justified by observation of spatiotemporally located things like meters, pointers and dials? I frame the problem of empirical coherence in terms of entailment: how could a non-spatiotemporal fundamental theory entail spatiotemporal (...)

    Recently in Analysis, Ned Markosian (2019) has argued that a popular theory in the metaphysics of time—the Spacetime Thesis—falsely predicts that a normal musical performance is just as aesthetically valuable if it is rotated “sideways,” that is, if it is made to occur all at once. However, this argument falsely assumes that changing how something is oriented in space, and changing its duration in time, are analogous. That said, assuming they were analogous, Markosian’s argument is still unsuccessful. For the analogy (...)

Moreover, it has important advantages over the alternative views these authors (...)

In this paper, I show that Markosian attacks a straw man as his argument targets a theory known to be false on empirical grounds. Four-dimensionalism rightly conceived in no way entails that time is identical to space. I then address two objections raised by Markosian against four-dimensionalism rightly conceived.

    Four simple postulates are presented, from which we derive a (3+1)‑dimensional structure, interpreted as ordinary space and time. We then derive further properties of space: isotropy and homogeneity; a rapid expansion within the first instant of time (i.e. inflation); and a continual and uniform expansionary pressure, due to a continual influx of (non-zero-point) energy that is uniformly distributed (i.e. dark energy). In addition, the time dimension is shown to have an "arrow". These results suggest that the four postulates may be (...)

This view requires that there is an unambiguous, absolute, cosmic-wide "now" at each instant. According to the second view about time, the universe is four dimensional. It is spread out in both space and time (...)

  44. Regularity Relationalism and the Constructivist Project.Syman Stevens - 2017 - British Journal for the Philosophy of Science:axx037.
    ABSTRACT It has recently been argued that Harvey Brown and Oliver Pooley’s ‘dynamical approach’ to special relativity should be understood as what might be called an ontologically and ideologically relationalist approach to Minkowski geometry, according to which Minkowski geometrical structure supervenes upon the symmetries of the best-systems dynamical laws for a material world with primitive topological or differentiable structure. Fleshing out the details of some such primitive structure, and a conception of laws according to which Minkowski geometry could so supervene, (...)

  45. Placement Permissivism and Logics of Location.Shieva Kleinschmidt - 2016 - Journal of Philosophy 113 (3):117-136.
    All of the current leading theories of location are parsimonious: they have at most one locative primitive, and the definitions of all of the other locative relations appeal to nothing beyond that primitive, mereological properties and relations, and basic logic. I argue that if we believe there can be extended, mereologically simple regions, we can construct cases that are incompatible with every possible parsimonious theory of location. In these cases, an object is contained within a simple region that is larger (...)

  46. Time Travel.John-Michael Kuczynski - 2016 - PHILOSOPHYPEDIA.
    It is clearly stated what time-travel would be, were it possible, and it is thereby shown that the very concept of time-travel is incoherent.

  47. Super-Relationism: Combining Eliminativism About Objects and Relationism About Spacetime.Baptiste Le Bihan - 2016 - Philosophical Studies 173 (8):2151-2172.
    I will introduce and motivate eliminativist super-relationism. This is the conjunction of relationism about spacetime and eliminativism about material objects. According to the view, the universe is a big collection of spatio-temporal relations and natural properties, and no substance (material or spatio-temporal) exists in it. The view is original since eliminativism about material objects, when understood as including not only ordinary objects like tables or chairs but also physical particles, is generally taken to imply substantivalism about spacetime: if properties are (...)

  48. The Deep Metaphysics of Space: An Alternative History and Ontology Beyond Substantivalism and Relationism.Edward Slowik - 2016 - Cham, Switzerland: Springer.
    This volume explores the inadequacies of the two standard conceptions of space or spacetime, substantivalism and relationism, and in the process, proposes a new historical interpretation of these physical theories. This book also examines and develops alternative ontological conceptions of space, such as the property theory of space and emergent spacetime hypotheses, and explores additional historical elements of seventeenth century theories and other metaphysical themes. Readers will learn about specific problems with the substantivalism versus relationism dichotomy. First, Newton and Leibniz (...)

    The paper presents a metaphysical characterization of spatiotemporal backgrounds from a realist perspective. The conceptual analysis is based on a heuristic sketch that encompasses the common formal traits of the major spacetime theories, such as Newtonian mechanics and general relativity. It is shown how this framework can be interpreted in a fully realist fashion, and what is the role of background structures in such a picture. In the end it is argued that, although backgrounds are a source of metaphysical discomfort, (...)

Zahedi - 2016 - XXXVII Max Born International Symposium, Noncommutative Geometry, Quantum Symmetries and Quantum Gravity II, Faculty of Physics and Astronomy, Wroclaw University, Poland (Supported by the European Union Framework Programme Horizon 2020).
    This article is a summary of an expanded version of my previous publication Ref. [ 1 ]. In particular, in Ref. [1] using a new axiomatic matrix approach – which has been formulated on the basis of ring theory and Clifford algebra – by first quantization (followed by a basic procedure of minimal coupling to the space-time geometry) of a special relativistic algebraic matrix equation, a certain massive form of gravitational field equations – with new matrix formalism and also a (...)
