    The Ineffable Now in Physics.Paul Merriam - manuscript
    While physicists know how to use quantum mechanics, there is no consensus on what quantum mechanics is a mechanics of. The aim of this paper is to introduce the beginning of what might turn out to be an interpretation of quantum mechanics—one that leaves all calculated probabilities intact. The basic idea is that quantum mechanics describes the objective world, but there must be added to it ineffable variables, one of which is the temporal 'now'. Ineffable variables are not 'hidden variables'.

    The Arrow of Time.Ted Dace - 2018 - Cosmos and History 14 (3):321-333.
    The foundation of irreversible, probabilistic time -- the classical time of conscious observation -- is the reversible and deterministic time of the quantum wave function. The tendency in physics is to regard time in the abstract, a mere parameter devoid of inherent direction, implying that a concept of real time begins with irreversibility. In reality time has no need for irreversibility, and every invocation of time implies becoming or flow. Neither symmetry under time reversal, of which Newton was well aware, (...)

    Part 1: Cosmological Constant Via a Planck Black-Hole Universe, a Simulation Hypothesis.Malcolm J. Macleod - manuscript
    The Simulation Hypothesis proposes that all of reality is in fact an artificial simulation, analogous to a computer simulation. Outlined here is a simple method for reproducing the principal cosmic microwave background parameters in a Planck-level simulation. The model is based on a proposed micro Planck-size black hole that embodies the Planck units. The simulation begins with a single micro black-hole and then expands by adding micro black-holes in incremental steps; these steps the simulation clock-rate and the origin of Planck (...)

    On the Logical Foundation of Physics (Part 2) -Draft.Alexandre Harvey Tremblay - manuscript
    The aim of this work is, first, to set the basis for a formal model of science, then, it is to show that the laws of physics are its theorems. Necessarily, all theories that are the logical product of science are theorems of our model. As this includes physics, our model is, therefore, its logical foundation. -/- Our model is an axiomatic realization of the participatory universe envisioned by John Archibald Wheeler, in which the observer's practice of science is associated (...)

    The (A)Temporal Emergence of Spacetime.Nick Huggett & Christian Wüthrich - 2018 - Philosophy of Science 85 (December):1190-1203.
    This paper examines two cosmological models of quantum gravity to investigate the foundational and conceptual issues arising from quantum treatments of the big bang. While the classical singularity is erased, the quantum evolution that replaces it may not correspond to classical spacetime: it may instead be a non-spatiotemporal region, which somehow transitions to a spatiotemporal state. The different kinds of transition involved are partially characterized, the concept of a physical transition without time is investigated, and the problem of empirical incoherence (...)

    Reading the Past in the Present.Nick Huggett - unknown
    Why is our knowledge of the past so much more ‘expansive’ (to pick a suitably vague term) than our knowledge of the future, and what is the best way to capture the difference(s) (i.e., in what sense is knowledge of the past more ‘expansive’)? One could reasonably approach these questions by giving necessary conditions for different kinds of knowledge, and showing how some were satisfied by certain propositions about the past, and not by corresponding propositions about the future. I take (...)

    Have We Lost Spacetime on the Way? Narrowing the Gap Between General Relativity and Quantum Gravity.Baptiste Le Bihan & Niels Linnemann - forthcoming - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics.
    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 signifi cantly 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 (...)

    On the Arrow of Spacetime.Alexandre Harvey Tremblay - manuscript
    Consistent with special relativity and statistical physics, here we construct a partition function of space-time events. The union of these two theories resolves longstanding problems in regards to time. It augments the standard description of time given by the (non-relativistic) arrow of time to one able to show the emergence of three macroscopic regimes of time: the past, the present, and the future, represented by space-like entropy, light-like entropy, and time-like entropy, respectively, and in a manner consistent with our experience (...)

    A number of general theories of physics provide a model for the fundamental rules that govern our universe, becoming a structural framework to which the new discoveries must conform. The theory of relativity is such a general theory. The theory of relativity is a complex theoretical framework that facilitates the understanding of the universal laws of physics. It is based on the curved space-time continuum fabric abstract concept, and it is well suited for interpreting cosmic events. More so, a general (...)

    Surreal Time and Ultratasks.Haidar Al-Dhalimy & Charles J. Geyer - 2016 - Review of Symbolic Logic 9 (4):836-847.
    This paper suggests that time could have a much richer mathematical structure than that of the real numbers. Clark & Read (1984) argue that a hypertask (uncountably many tasks done in a finite length of time) cannot be performed. Assuming that time takes values in the real numbers, we give a trivial proof of this. If we instead take the surreal numbers as a model of time, then not only are hypertasks possible but so is an ultratask (a sequence which (...)

    Too Many Conceptions of Time? McTaggart's Views Revisited.Gregor Schiemann & Brigitte Falkenburg - 2016 - In Stamatios Gerogiorgaki (ed.), Time and Tense (Basic Philosophical Concepts).
    John Ellis McTaggart defended an idealistic view of time in the tradition of Hegel and Bradley. His famous paper makes two independent claims (McTaggart1908): First, time is a complex conception with two different logical roots. Second, time is unreal. To reject the second claim seems to commit to the first one, i.e., to a pluralistic account of time. We compare McTaggarts views to the most important concepts of time investigated in physics, neurobiology, and philosophical phenomenology. They indicate that a unique, (...)

    The General Theory of Relativity (GR) and the Dynamic Universe (DU) are evaluated in how they explain frequencies of atomic clocks. DU and GR predict the frequencies with equal accuracy, but their explanations, the postulates they apply in the explanations and the word-views that come along with them are entirely different. The central argument is that if unified and under- standable physics is appreciated, then DU deserves to be taken as a viable alternative to GR. In GR different frequencies of (...)

    Teleportative Observers Versus Special Relativity Observers: Work in Progress.James Goetz - manuscript
    Various authors argue that special relativity implies eternalism. For example, special relativity observers are limited by the relativity of simultaneity and cannot detect a preferred universal chronology, which is an important premise for the Rietdijk–Putnam argument which implies eternalism. However, I introduce "teleportative observers" which cohere with wormhole theory based on general relativity. Teleportative observers do not teleport objects but use hypothetical teleportative sight to detect every event in every quantum system of the universe. The teleportative sight permits detection at (...)

Part I takes seriously the doctrine that modern physics should be treated as the primary guide to the nature of time. To this end, it offers an analysis of the various conceptions of time that emerge in the context of various physical theories and, furthermore, an analysis of the relation between these conceptions of time and the more orthodox philosophical views on the nature (...)

    Memory as a Property of Nature.Ted Dace - 2018 - Axiomathes 28 (5):507-519.
    Prerequisite to memory is a past distinct from present. Because wave evolution is both continuous and time-reversible, the undisturbed quantum system lacks a distinct past and therefore the possibility of memory. With the quantum transition, a reversibly evolving superposition of values yields to an irreversible emergence of definite values in a distinct and transient moment of time. The succession of such moments generates an irretrievable past and thus the possibility of memory. Bohm’s notion of implicate and explicate order provides a (...)

    I use Kant's theory of the transcendental ideality of time to answer McTaggart's argument for the unreality of time. McTaggart's argument is that the atemporal C-series (the logical atoms of all moments) must be regarded as the metaphysical foundation of the B-series, the non-dynamic world of objective temporal relations of events being earlier or later than others. That B-series (having a qualitative aspect that is not indifferent to the direction of time) is essentially an ossification of the A-series--the dynamic flow (...)

    Quantum Gravity, Timelessness, and the Contents of Thought.David Braddon-Mitchell & Kristie Miller - forthcoming - Philosophical Studies:1-23.
    A number of recent theories of quantum gravity lack a one-dimensional structure of ordered temporal instants. Instead, according to many of these views, our world is either best represented as a single three-dimensional object, or as a configuration space composed of such three-dimensional objects, none of which bear temporal relations to one another. Such theories will be empirically self-refuting unless they can accommodate the existence of conscious beings capable of representation. For if representation itself is impossible in a timeless world, (...)

    Fundamentality and Time’s Arrow.Christian Loew - 2018 - Philosophy of Science 85 (3):483-500.
    The distribution of matter in our universe is strikingly time asymmetric. Most famously, the Second Law of Thermodynamics says that entropy tends to increase toward the future but not toward the past. But what explains this time-asymmetric distribution of matter? In this paper, I explore the idea that time itself has a direction by drawing from recent work on grounding and metaphysical fundamentality. I will argue that positing such a direction of time, in addition to time-asymmetric boundary conditions, enables a (...)

    The aim of this article is to analyse the relation between the second law of thermodynamics and the so-called arrow of time.

Next I review versions of the second law in the work of Carnot, Clausius, Kelvin, Planck, Gibbs, Caratheodory and Lieb and Yngvason, and investigate their connection with these aspects of the arrow of time.

    Why Quantum Mechanics Favors Adynamical and Acausal Interpretations Such as Relational Blockworld Over Backwardly Causal and Time-Symmetric Rivals.Michael Silberstein, Michael Cifone & William Mark Stuckey - 2008 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 39 (4):736-751.
    We articulate the problems posed by the quantum liar experiment (QLE) for backwards causation interpretations of quantum mechanics, time-symmetric accounts and other dynamically oriented local hidden variable theories. We show that such accounts cannot save locality in the case of QLE merely by giving up “lambda-independence.” In contrast, we show that QLE poses no problems for our acausal Relational Blockworld interpretation of quantum mechanics, which invokes instead adynamical global constraints to explain Einstein–Podolsky–Rosen (EPR) correlations and QLE. We make the case (...)

    I will defend two claims. First, Schaffer's priority monism is in tension with many research programs in quantum gravity. Second, priority monism can be modified into a view more amenable to this physics. The first claim is grounded in the fact that promising approaches to quantum gravity such as loop quantum gravity or string theory deny the fundamental reality of spacetime. Since fundamental spacetime plays an important role in Schaffer's priority monism by being identified with the fundamental structure, namely the (...)

    For millennia people have speculated about the nature of time—without success. Time plays a role with all processes and events studied by all the disciplines. It is reported here that the existence of time is a direct consequence of the existence of space. Space exists, and it continues to exist. Space is there, and it continues to be there. Space exists as place, the three-dimensional place that matter can occupy. The three-dimensional extension of spatial-place is measured with a ruler of (...)

    This paper relates both to the metaphysics of probability and to the physics of time asymmetry. Using the formalism of decoherent histories, it investigates whether intuitions about intrinsic time directedness that are often associated with probability can be justified in the context of no-collapse approaches to quantum mechanics. The standard approach to time symmetry in the decoherent histories literature is criticised, and an alternative approach is proposed, based on two decoherence conditions within the one-vector formalism. In turn, considerations of forwards (...)

    I will discuss the notion of time and spatial finiteness from the perspective of observational cosmology. Our observed universe is well described at early times by small fluctuations in the spatial gravitational field, distributed homogeneously and isotropically on an otherwise smooth background spacetime. The dominant paradigm for an even earlier phase of the evolution of our universe typically generates a space similar to what we observe but with vastly larger spatial extent. Even in a classical theory, the fact that we (...)

    On one popular view, the general covariance of gravity implies that change is relational in a strong sense, such that all it is for a physical degree of freedom to change is for it to vary with regard to a second physical degree of freedom. At a quantum level, this view of change as relative variation leads to a fundamentally timeless formalism for quantum gravity. Here, we will show how one may avoid this acute ‘problem of time’.

    Metaphysical theories of change incorporate substantive commitments to theories of persistence. The two most prominent classes of such theories are endurantism and perdurantism. Defenders of endurance-style accounts of change, such as Klein, Hinchliff, and Oderberg, do so through appeal to a priori intuitions about change. We argue that this methodology is understandable but mistaken—an adequate metaphysics of change must accommodate all experiences of change, not merely intuitions about a limited variety of cases. Once we examine additional experiences of change, particularly (...)

    Relativity Theory May Not Have the Last Word on the Nature of Time: Quantum Theory and Probabilism.Nicholas Maxwell - 2017 - In G. Ghirardi & S. Wuppulur (eds.), Space, Time and the Limits of Human Understanding. Springer. pp. 109-124.
    Two radically different views about time are possible. According to the first, the universe is three dimensional. It has a past and a future, but that does not mean it is spread out in time as it is spread out in the three dimensions of space. 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 (...)

    From Permanence to Total Availability: A Quantum Conceptual Upgrade.Massimiliano Sassoli de Bianchi - 2012 - Foundations of Science 17 (3):223-244.
    We consider the classical concept of time of permanence and observe that its quantum equivalent is described by a bona fide self-adjoint operator. Its interpretation, by means of the spectral theorem, reveals that we have to abandon not only the idea that quantum entities would be characterizable in terms of spatial trajectories but, more generally, that they would possess the very attribute of spatiality. Consequently, a permanence time shouldn’t be interpreted as a “time” in quantum mechanics, but as a measure (...)

    The Oxford Handbook of Philosophy of Time.Craig Callender (ed.) - 2011 - Oxford University Press.
    As the study of time has flourished in the physical and human sciences, the philosophy of time has come into its own as a lively and diverse area of academic research. Philosophers investigate not just the metaphysics of time, and our experience and representation of time, but the role of time in ethics and action, and philosophical issues in the sciences of time, especially with regard to quantum mechanics and relativity theory. This Handbook presents twenty-three specially written essays by leading (...)

    The Future of the Philosophy of Time.Adrian Bardon (ed.) - 2011 - Routledge.
    The last century has seen enormous progress in our understanding of time. This volume features original essays by the foremost philosophers of time discussing the goals and methodology of the philosophy of time, and examining the best way to move forward with regard to the field's core issues. The collection is unique in combining cutting edge work on time with a focus on the big picture of time studies as a discipline. The major questions asked include: What are the implications (...)

    Relativity and the Moving Spotlight.Bradford Skow - 2009 - Journal of Philosophy 106 (12):666-678.
    A standard objection to the moving spotlight theory of time is that it is incompatible with special relativity. I show how to formulate the moving spotlight theory so that it is perfectly compatible with special relativity. There is no need to re-interpret the physics or add to it a notion of absolute simultaneity.

    A Search for the de Broglie Particle Internal Clock by Means of Electron Channeling.P. Catillon, N. Cue, M. J. Gaillard, R. Genre, M. Gouanère, R. G. Kirsch, J. -C. Poizat, J. Remillieux, L. Roussel & M. Spighel - 2008 - Foundations of Physics 38 (7):659-664.
    The particle internal clock conjectured by de Broglie in 1924 was investigated in a channeling experiment using a beam of ∼80 MeV electrons aligned along the 〈110〉 direction of a 1 μm thick silicon crystal. Some of the electrons undergo a rosette motion, in which they interact with a single atomic row. When the electron energy is finely varied, the rate of electron transmission at 0° shows a 8% dip within 0.5% of the resonance energy, 80.874 MeV, for which the (...)

    Some Problems Concerning Language and Physics.Adonai Sant’Anna & Gabriel Guerrer - 2007 - Synthese 154 (3):467-484.
    We discuss three problems concerning the use of formal languages in theoretical physics: (i) the definability of time and spacetime in classical physical theories; (ii) how to cope with indistinguishable elementary particles in quantum mechanics without labeling them; and (iii) how to get a formal picture of quantum states jumping.

    Philosophy of Physics.Jeremy Butterfield & John Earman (eds.) - 2007 - Elsevier.
    The ambition of this volume is twofold: to provide a comprehensive overview of the field and to serve as an indispensable reference work for anyone who wants to work in it. For example, any philosopher who hopes to make a contribution to the topic of the classical-quantum correspondence will have to begin by consulting Klaas Landsman’s chapter. The organization of this volume, as well as the choice of topics, is based on the conviction that the important problems in the philosophy (...)

    Enduring Special Relativity.Kristie Miller - 2004 - Southern Journal of Philosophy 42 (3):349-370.
    Endurantism is not inconsistent with the theory of special relativity, or so I shall argue. Endurantism is not committed to presentism, and thus not committed to a metaphysics that is at least prima facie inconsistent with special relativity. Nor is special relativity inconsistent with the idea that objects are wholly present at a time just if all of their parts co-exist at that time. For the endurantist notion of co-existence in terms of which “wholly present” is defined, is not, I (...)
