  1. Have we Lost Spacetime on the Way? Narrowing the Gap between General Relativity and Quantum Gravity.Baptiste Le Bihan & Niels Siegbert Linnemann - 2019 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 65 (C):112-121.
    Important features of space and time are taken to be missing in quantum gravity, allegedly requiring an explanation of the emergence of spacetime from non-spatio-temporal theories. In this paper, we argue that the explanatory gap between general relativity and non-spatio-temporal quantum gravity theories might significantly be reduced with two moves. First, we point out that spacetime is already partially missing in the context of general relativity when understood from a dynamical perspective. Second, we argue that most approaches to quantum gravity (...)

    Hints towards the emergent nature of gravity.Niels S. Linnemann & Manus R. Visser - 2018 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 64:1-13.
    A possible way out of the conundrum of quantum gravity is the proposal that general relativity (GR) emerges from an underlying microscopic description. Despite recent interest in the emergent gravity program within the physics as well as the philosophy community, an assessment of the general motivation for this idea is lacking at the moment. We intend to fill this gap in the literature by discussing the main arguments in favour of the hypothesis that the metric field and its dynamics are (...)

    On the Status of Newtonian Gravitational Radiation.Niels Linnemann & James Read - 2021 - Foundations of Physics 51 (2):1-16.
    We discuss the status of gravitational radiation in Newtonian theories. In order to do so, we consider various options for interpreting the Poisson equation as encoding propagating solutions, reflect on the extent to which limit considerations from general relativity can shed light on the Poisson equation’s conceptual status, and discuss various senses in which the Poisson equation counts as a dynamical equation.

    On the empirical coherence and the spatiotemporal gap problem in quantum gravity: and why functionalism does not (have to) help.Niels Linnemann - 2020 - Synthese 199 (S2):395-412.
    The empirical coherence problem of quantum gravity is the worry that a theory which does not fundamentally contain local beables located in space and time—such as is arguably the case for certain approaches to quantum gravity—cannot be connected to measurements and thus has its prospects of being empirically adequate undermined. Spacetime functionalism à la Lam and Wüthrich is said to solve this empirical coherence problem as well as bridging a severe conceptual gap between spatiotemporal structures of classical spacetime theories on (...)

  7. On metaphysically necessary laws from physics.Niels Linnemann - 2020 - European Journal for Philosophy of Science 10 (2):1-13.
    How does metaphysical necessity relate to the modal force often associated with natural laws? Fine argues that natural necessity can neither be obtained from metaphysical necessity via forms of restriction nor of relativization — and therefore pleads for modal pluralism concerning natural and metaphysical necessity. Wolff, 898–906, 2013) aims at providing illustrative examples in support of applying Fine’s view to the laws of nature with specific recourse to the laws of physics: On the one hand, Wolff takes it that equations (...)

    Better guesses.Niels Linnemann & Feraz Azhar - forthcoming - Philosophy and Phenomenological Research.
    It has recently become popular to analyze scenarios in which we guess, in terms of a trade‐off between the accuracy of our guess (namely, its credence) and its specificity (namely, how many answers it rules out). Dorst and Mandelkern describe an account of guessing, based on epistemic utility theory (EUT), in which permissible guesses vary depending on how one weighs accuracy against specificity. We provide a minimal formal account of guessing that: (i) does not employ EUT, but rests on how (...)

    The constructivist’s programme and the problem of pregeometry.Niels Linnemann & Kian Salimkhani - 2021
    Prominently, Norton argues against constructivism about spacetime theories, the doctrine that spatiotemporal structure in the dynamics only has derivative status. Among other things, he accuses Brown and Pooley's dynamical approach to special relativity of being merely half-way constructivist: setting up relativistic fields as presupposed in the dynamical approach to special relativity already requires spatiotemporal background structure. We first assess a recent solution proposal by Menon and then provide our very own defense of constructivism along two independent lines.

  10. GR as a classical spin-2 theory?Niels Linnemann, Chris Smeenk & Mark Robert Baker - forthcoming - Philosophy of Science.
    The self-interaction spin-2 approach to GR has been extremely influential in the particle physics community. Leaving no doubt regarding its heuristic value, we argue that any view of the metric field of GR as nothing but a stand-in for a self-coupling field in at spacetime runs into a dilemma: either the view is physically incomplete in so far as it requires recourse to GR after all, or it leads to an absurd multiplication of alternative viewpoints on GR rendering any understanding (...)

  11. What we cannot learn from analogue experiments.Karen Crowther, Niels S. Linnemann & Christian Wüthrich - 2019 - Synthese (Suppl 16):1-26.
    Analogue experiments have attracted interest for their potential to shed light on inaccessible domains. For instance, ‘dumb holes’ in fluids and Bose–Einstein condensates, as analogues of black holes, have been promoted as means of confirming the existence of Hawking radiation in real black holes. We compare analogue experiments with other cases of experiment and simulation in physics. We argue—contra recent claims in the philosophical literature—that analogue experiments are not capable of confirming the existence of particular phenomena in inaccessible target systems. (...)

  12. Renormalizability, Fundamentality, and a Final Theory: The Role of UV-Completion in the Search for Quantum Gravity.Karen Crowther & Niels Linnemann - 2017 - British Journal for the Philosophy of Science 70 (2):377-406.
    Principles are central to physical reasoning, particularly in the search for a theory of quantum gravity, where novel empirical data are lacking. One principle widely adopted in the search for QG is ultraviolet completion: the idea that a theory should hold up to all possible high energies. We argue— contra standard scientific practice—that UV-completion is poorly motivated as a guiding principle in theory-construction, and cannot be used as a criterion of theory-justification in the search for QG. For this, we explore (...)

    On the Non-identity Causal Theory of Spacetime from Causal Set Theory.Rasmus Jaksland & Niels Linnemann - forthcoming - Erkenntnis:1-22.
    The aim to provide a causal theory of spacetime is not new. The overall program, however, was largely deemed unsuccessful, chiefly due to criticism voiced by Smart (Monist 53:385–395, 1969), Nerlich (Br J Philos Sci 33(4):361–388, 1982) and Earman (Synthese 24:74–86, 1972). Recently, Baron and Le Bihan (Noûs 58:202–224, 2023) have argued that developments in contemporary physics should make us reconsider this verdict. More precisely, they argue the emergence of spacetime from causal set theory (CST), where “the metric structure of (...)

    Miracles persist: a reply to Sus.James Read & Niels Linnemann - 2022 - European Journal for Philosophy of Science 12 (1):1-10.
    In a recent article in this journal, Sus purports to account for what have been identified as the ‘two miracles’ of general relativity—that (1) the local symmetries of all dynamical equations for matter fields coincide, and (2) the symmetries of the dynamical equations governing matter fields coincide locally with the symmetries of the metric field—by application of the familiar result that every symmetry of the action is also a symmetry of the resulting equations of motion. In this reply, we argue (...)

  19. The strong arm of the law: a unified account of necessary and contingent laws of nature.Salim Hirèche, Niels Linnemann, Robert Michels & Lisa Vogt - 2021 - Synthese 199 (3-4):10211-10252.
    A common feature of all standard theories of the laws of nature is that they are "absolutist": They take laws to be either all metaphysically necessary or all contingent. Science, however, gives us reason to think that there are laws of both kinds, suggesting that standard theories should make way for "non-absolutist" alternatives: theories which accommodate laws of both modal statuses. In this paper, we set out three explanatory challenges for any candidate non-absolutist theory and discuss the prospects of the (...)

  20. Quantum Gravity in a Laboratory?Nick Huggett, Niels S. Linnemann & Mike D. Schneider - 2023
    It has long been thought that observing distinctive traces of quantum gravity in a laboratory setting is effectively impossible, since gravity is so much weaker than all the other familiar forces in particle physics. But the quantum gravity phenomenology community today seeks to do the (effectively) impossible, using a challenging novel class of `tabletop' Gravitationally Induced Entanglement (GIE) experiments, surveyed here. The hypothesized outcomes of the GIE experiments are claimed by some (but disputed by others) to provide a `witness' of (...)

    How Not to Establish the Non-renormalizability of Gravity.Juliusz Doboszewski & Niels Linnemann - 2018 - Foundations of Physics 48 (2):237-252.
    General relativity cannot be formulated as a perturbatively renormalizable quantum field theory. An argument relying on the validity of the Bekenstein–Hawking entropy formula aims at dismissing gravity as non-renormalizable per se, against hopes that d-dimensional GR could turn out to have a non-perturbatively renormalizable d–dimensional quantum field theoretic formulation. In this note we discuss various forms of highly problematic semi-classical extrapolations assumed by both sides of the debate concerning what we call The Entropy Argument, and show that a large class (...)

  22. The modal status of the laws of nature. Tahko’s hybrid view and the kinematical/dynamical distinction.Salim Hireche, Niels Linnemann, Robert Michels & Lisa Vogt - 2021 - European Journal for Philosophy of Science 11 (1):1-15.
    In a recent paper, Tuomas Tahko has argued for a hybrid view of the laws of nature, according to which some physical laws are metaphysically necessary, while others are metaphysically contingent. In this paper, we show that his criterion for distinguishing between these two kinds of laws — which crucially relies on the essences of natural kinds — is on its own unsatisfactory. We then propose an alternative way of drawing the metaphysically necessary/contingent distinction for laws of physics based on (...)

  25. Are all laws of nature created equal? Meta-laws versus more necessary laws.Salim Hirèche, Niels Linnemann & Robert Michels - 2023 - Erkenntnis:1-19.
    Two approaches to elevating certain laws of nature over others have come to prominence recently. On the one hand, according to the meta-laws approach, there are meta-laws, laws which relate to laws as those laws relate to particular facts. On the other hand, according to the modal, or non-absolutist, approach, some laws are necessary in a stricter sense than others. Both approaches play an important role in current research, questioning the ‘orthodoxy’ represented by the leading philosophical theories of natural laws—Humeanism, (...)

    Holography without holography: How to turn inter-representational into intra-theoretical relations in AdS/CFT.Rasmus Jaksland & Niels S. Linnemann - 2020 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 71:101-117.
    We show by means of the AdS/CFT correspondence in the context of quantum gravity how inter-representational relations—loosely speaking relations among different equivalent representations of one and the same physics—can play out as a tool for intra-theoretical developments and thus boost theory development in the context of discovery. More precisely, we first show that, as a duality, the AdS/CFT correspondence cannot in itself testify to the quantum origin of gravity (though it may be utilized for this purpose). We then establish through (...)

    Predictive uncertainty in auditory sequence processing.Niels Chr Hansen & Marcus T. Pearce - 2014 - Frontiers in Psychology 5:88945.
    Previous studies of auditory expectation have focused on the expectedness perceived by listeners retrospectively in response to events. In contrast, this research examines predictive uncertainty —a property of listeners' prospective state of expectation prior to the onset of an event. We examine the information-theoretic concept of Shannon entropy as a model of predictive uncertainty in music cognition. This is motivated by the Statistical Learning Hypothesis, which proposes that schematic expectations reflect probabilistic relationships between sensory events learned implicitly through exposure. Using (...)

    This paper pushes back against the Democritean-Newtonian tradition of assuming a strict conceptual dichotomy between spacetime and matter. Our approach proceeds via the more narrow distinction between modified gravity/spacetime and dark matter. A prequel paper argued that the novel field Φ postulated by Berezhiani and Khoury's 'superfluid dark matter theory' is as much matter as anything could possibly be, but also below the critical temperature for superfluidity as much spacetime as anything could possibly be. Here we introduce and critically evaluate (...)

    The Phenomenologizing of Primal-Phenomenality: Husserl and the Boundaries of the Phenomenology of Time.Luis Niel - 2013 - Husserl Studies 29 (3):211-230.
    This paper focuses on the methodical disclosure of the lowest level of the constitution of time in Husserl’s phenomenology of time (especially in the C-Manuscripts), following this leading question: is it at all possible to disclose phenomenologically the primal-phenomenal constituting stream of consciousness? First, I address the different levels of constitution in order to focus on the ultimate level. Second, I analyse the “intentionality” of the primal-stream, by means of differentiating it from act-intentionality. Third, I outline the methodical function of (...)
