  1. String Theory, Loop Quantum Gravity and Eternalism.Baptiste Le Bihan - 2020 - European Journal for Philosophy of Science 10:17.
    Eternalism, the view that what we regard locally as being located in the past, the present and the future equally exists, is the best ontological account of temporal existence in line with special and general relativity. However, special and general relativity are not fundamental theories and several research programs aim at finding a more fundamental theory of quantum gravity weaving together all we know from relativistic physics and quantum physics. Interestingly, some of these approaches assert that time is not fundamental. (...)

  • A New Perspective On Time And Physical Laws.Lucy James - unknown
    Callender claims that `time is the great informer', meaning that the direction in which our `best' physical theories inform are temporal. This is intended to be a metaphysical claim, and as such expresses a relationship between the physical world and information-gathering systems such as ourselves. This paper gives two counterexamples to this claim, illustrating the fact that time and informative strength doubly dissociate, so the claim cannot be about physical theories in general. The first is a case where physical theories (...)

  • What Does the World Look Like According to Superdeterminism?Augustin Baas & Baptiste Le Bihan - 2020 - British Journal for the Philosophy of Science.
    The violation of Bell inequalities seems to establish an important fact about the world: that it is non-local. However, this result relies on the assumption of the statistical independence of the measurement settings with respect to potential past events that might have determined them. Superdeterminism refers to the view that a local, and determinist, account of Bell inequalities violations is possible, by rejecting this assumption of statistical independence. We examine and clarify various problems with superdeterminism, looking in particular at its (...)

  • From Spacetime to Space and Time: A Reply to Markosian.Baptiste Le Bihan - 2020 - Analysis 80 (3):456-462.
    In a recent article, Ned Markosian gives an argument against four-dimensionalism understood as the view that time is one of four identical dimensions that constitute a single four-dimensional manifold. 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.

  • L'éternité sans le temps.Baptiste Le Bihan - 2018 - Revue Philosophique De Louvain 116 (3):441-462.
    L'éternalisme implique une forme exotique d'éternité : toute entité, aussi éphémère soit-elle et quelle que soit sa localisation dans le temps, existe relativement à toute autre localisation temporelle. Cet essai vise, premièrement, à défendre l'éternalisme en exhibant les difficultés rédhibitoires du présentisme et du non-futurisme, et deuxièmement à examiner de quelle manière l'éternalisme pourrait être amendé à l'aune d'une affirmation que l'on trouve sous la plume de certains physiciens, à savoir que, fondamentalement, le temps n'existe pas. La disparition du temps (...)

  • Modal Realism and the Possibility of Island Universes: Why There Are No Possible Worlds.Jiri Benovsky - forthcoming - Metaphysica.
    I defend Lewisian modal realism against objections arising from the possibility of 'Island Universes' and other similar cases. The problem comes from Lewis' claim that possible worlds are spatio-temporally isolated. I suggest a modification of Lewisian modal realism in order to avoid this family of objections. This modification may sound quite radical since it amounts to abandoning the very notion of a possible world, but as radical as it may sound it in fact remains well in the spirit of Lewis' (...)

  • Spacetime functionalism from a realist perspective.Vincent Lam & Christian Wüthrich - forthcoming - Synthese:1-19.
    In prior work, we have argued that spacetime functionalism provides tools for clarifying the conceptual difficulties specifically linked to the emergence of spacetime in certain approaches to quantum gravity. We argue in this article that spacetime functionalism in quantum gravity is radically different from other functionalist approaches that have been suggested in quantum mechanics and general relativity: in contrast to these latter cases, it does not compete with purely interpretative alternatives, but is rather intertwined with the physical theorizing itself at (...)

  • On the empirical coherence and the spatiotemporal gap problem in quantum gravity: and why functionalism does not (have to) help.Niels Linnemann - forthcoming - Synthese:1-18.
    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 (...)

  • Spacetime Emergence in Quantum Gravity: Functionalism and the Hard Problem.Baptiste Le Bihan - forthcoming - Synthese.
    Spacetime functionalism is the view that spacetime is a functional structure implemented by a more fundamental ontology. 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 (...)
