  1. Time and irreversibility in an accelerating universe.Gustavo E. Romero & Daniela Pérez - 2011 - International Journal of Modern Physics D 20:2831-2838.
    It is a remarkable fact that all processes occurring in the observable universe are irre- versible, whereas the equations through which the fundamental laws of physics are formu- lated are invariant under time reversal. The emergence of irreversibility from the funda- mental laws has been a topic of consideration by physicists, astronomers and philosophers since Boltzmann's formulation of his famous \H" theorem. In this paper we shall discuss some aspects of this problem and its connection with the dynamics (...)

  2. (1 other version)Counterfactuals, Irreversible Laws and The Direction of Time.Terrance A. Tomkow - manuscript
    The principle of Information Conservation or Determinism is a governing assumption of physical theory. Determinism has counterfactual consequences. It entails that if the present were different, then the future would be different. But determinism is temporally symmetric: it entails that if the present were different, the past would also have to be different. This runs contrary to our commonsense intuition that what has happened in the future depends on the past in a way the past does not depend on the (...)

  3. Time's Arrow and Irreversibility in Time‐Asymmetric Quantum Mechanics.Mario Castagnino, Manuel Gadella & Olimpia Lombardi - 2005 - International Studies in the Philosophy of Science 19 (3):223 – 243.
    The aim of this paper is to analyze time-asymmetric quantum mechanics with respect to the problems of irreversibility and of time's arrow. We begin with arguing that both problems are conceptually different. Then, we show that, contrary to a common opinion, the theory's ability to describe irreversible quantum processes is not a consequence of the semigroup evolution laws expressing the non-time-reversal invariance of the theory. Finally, we argue that time-asymmetric quantum mechanics, either in Prigogine's version (...)

  4. 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 (...) or the dimensionality of the future, can be addressed philosophically using the tools from current astrophysics research and, in particular, from the study of black holes and gravitational waves.

  5. A Fundamentally Irreversible World as an Opportunity towards a Consistent Understanding of Quantum and Cosmological Contexts.Tributsch Helmut Helmuttributsch@Aliceit - 2016 - Lournal of Modern Physics 7:1455-1482.
    In a preceding publication a fundamentally oriented and irreversible world was shown to be de- rivable from the important principle of least action. A consequence of such a paradigm change is avoidance of paradoxes within a “dynamic” quantum physics. This becomes essentially possible because fundamental irreversibility allows consideration of the “entropy” concept in elementary processes. For this reason, and for a compensation of entropy in the spread out energy of the wave, the duality of particle and wave has to (...)

  6. Irreversibility and Complexity.Lapin Yair - manuscript
    Complexity is a relatively new field of study that is still heavily influenced by philosophy. However, with the advent of modern computing, it has become easier to conduct thorough investigations of complex systems using computational simulations. Despite significant progress, there remain certain characteristics of complex systems that are difficult to comprehend. To better understand these features, information can be applied using simple models of complex systems. The concepts of Shannon's information theory, Kolgomorov complexity, and logical depth are helpful in this (...)

  7. About Appearance of the Irreversibility.Igor V. Lebed - 2014 - Open Journal of Fluid Dynamics 4 (3):298-320.
    The inevitability of arising in equations of kinetics and hydrodynamics irreversibility not contained in original equations of classic mechanics is substantiated. It is established that transfer of information about the direction of system evolution from initial conditions to resulting equations is the consequence of losing information about the position of an individual particle in space, which takes place at roughening description. It is shown that the roughening with respect to impact parameters of colliding particles is responsible for appearance of (...)

  8. 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 (...)

  9. The Time Flow Manifesto CHAPTER 6 PHILOSOPHICAL ISSUES.Andrew Holster - manuscript
    ‘Philosophy’ today has come to mean the academic ideological disputes between various grandiose ‘meta-philosophies’, rather than the content or explanation of the real problems and issues. I illustrate typical expressions of the conventional ‘scientific' anti-realist philosophy of time here, and how far it has infiltrated the scientific world view.

  11. Time in the ontology of Cornelius Castoriadis.Alexandros Schismenos - 2018 - SOCRATES 5 (3 & 4):64-81.
    We can locate the problematic of time within three philosophical questions, which respectively designate three central areas of philosophical reflection and contemplation. These are: 1) The ontological question, i.e. 'what is being?' 2) The epistemological question, i.e. 'what can we know with certainty?' 3) The existential question, i.e. 'what is the meaning of existence?' These three questions, which are philosophical, but also scientific and political, as they underline the political and moral question of truth and justice, arise from the (...)

  12. The criterion for time symmetry of probabilistic theories and the reversibility of quantum mechanics.Andrew Thomas Holster - 2003 - New Journal of Physics 5 (130).
    Physicists routinely claim that the fundamental laws of physics are 'time symmetric' or 'time reversal invariant' or 'reversible'. In particular, it is claimed that the theory of quantum mechanics is time symmetric. But it is shown in this paper that the orthodox analysis suffers from a fatal conceptual error, because the logical criterion for judging the time symmetry of probabilistic theories has been incorrectly formulated. The correct criterion requires symmetry between future-directed laws and past-directed laws. This (...)

    If an asymmetry in time does not arise from the fundamental dynamical laws of physics, it may be found in special boundary conditions. The argument normally goes that since thermodynamic entropy in the past is lower than in the future according to the Second Law of Thermodynamics, then tracing this back to the time around the Big Bang means the universe must have started off in a state of very low thermodynamic entropy: the Thermodynamic Past Hypothesis.

  14. The quantum mechanical time reversal operator.Andrew Thomas Holster - unknown
    The analysis of the reversibility of quantum mechanics depends upon the choice of the time reversal operator for quantum mechanical states. The orthodox choice for the time reversal operator on QM states is known as the Wigner operator, T*, where * performs complex conjugation. The peculiarity is that this is not simply the unitary time reversal operation, but an anti-unitary operator, involving complex conjugation in addition to ordinary time reversal. The alternative choice is the Racah operator, (...)

  15. The time asymmetry of quantum mechanics and concepts of physical directionality of time Part 1.Andrew Thomas Holster - manuscript
    This is Part 1 of a four part paper, intended to redress some of the most fundamental confusions in the subject of physical time directionality, and represent the concepts accurately. There are widespread fallacies in the subject that need to be corrected in introductory courses for physics students and philosophers. We start in Part 1 by analysing the time reversal symmetry of quantum probability laws. Time reversal symmetry is defined as the property of invariance under the (...) reversal transformation, T: t --> -t. It is shown that quantum mechanics (classical or relativistic) is strongly time asymmetric in its probability laws. This contradicts the orthodox analysis, found throughout the conventional literature on physical time, which claims that quantum mechanics is time symmetric or reversible. This is widely claimed as settled scientific fact, and large philosophical and scientific conclusions are drawn from it. But it is an error. The fact is that while quantum mechanics is widely claimed to be reversible on the basis of two formal mathematical properties (that it does have), these properties do not represent invariance under the time reversal transformation. A recent experiment (Batalhão at alia, 2015) showing irreversibility of quantum thermodynamics is discussed as an illustration of this result. Most physicists remain unaware of the errors, decades after they were first demonstrated. Orthodox specialists in the philosophy of time who are aware of the error continue to refer to the ‘time symmetry’ or ‘reversibility’ of quantum mechanics anyway – and exploit the ambiguity to claim false implications about physical time reversal symmetry in nature. The excuse for perpetrating the confusion is that, since it is has now become customary to refer to the formal properties of quantum mechanics as ‘reversibility’ or ‘time reversal symmetry’, we should just keep referring to them by this name, even though they are not time reversal symmetry. This causes endless confusion, in attempts to explain the physical irreversibility of our universe, and in philosophical discussions of implications of physics for the nature of time. The failure of genuine time reversal symmetry in quantum mechanics changes the interpretation of modern physics in a deep way. It changes the problem of explaining the real irreversibility found throughout nature. (shrink)

  16. Time and the Quantum Measurement Problem.Ted Dace - 2021 - International Journal of Quantum Foundations Supplement 3 (1):32-43.
    The quantum measurement problem resolves according to the twofold nature of time. Whereas the continuous evolution of the wave function reflects the fundamental nature of time as continuous presence, the collapse of the wave function indicates the subsidiary aspect of time as the projection of instantaneity from the ongoing present. Each instant irreversibly emerges from the reversible temporal continuum implicit in the smoothly propagating wave function. The basis of this emergence is periodic conflict between quantum systems, the (...)

  18. Negative-Energy Matter and the Direction of Time.J. C. Lindner - forthcoming
    This report offers a modern perspective on the problem of negative energy, based on a reexamination of the concept of time direction as it arises in a classical and quantum-mechanical context. From this analysis emerges an improved understanding of the general-relativistic stress-energy of matter as being a manifestation of local variations in the energy density of zero-point vacuum fluctuations. Based on those developments, a set of axioms is proposed from which are derived generalized gravitational field equations which actually constitute (...)

  19. Creative Undecidability of Real-World Dynamics and the Emergent Time Hierarchy.Andrei P. Kirilyuk - 2020 - FQXi Essay Contest 2019-2020 “Undecidability, Uncomputability, and Unpredictability”.
    The unreduced solution to the arbitrary interaction problem, absent in the standard theory framework, reveals many equally real and mutually incompatible system configurations, or "realizations". This is the essence of universal dynamic undecidability, or multivaluedness, and the ensuing causal randomness (unpredictability), non-computability, irreversible time flow (evolution, emergence), and dynamic complexity of every real system, object, or process. This creative undecidability of real-world dynamics provides causal explanations for "quantum mysteries", relativity postulates, cosmological problems, and the huge efficiency of high-complexity phenomena, (...)

  20. Emerging viral threats and the simultaneity of the non-simultaneous: zooming out in times of Corona.Hub Zwart - 2020 - Medicine, Health Care and Philosophy 23 (4):589-602.
    This paper addresses global bioethical challenges entailed in emerging viral diseases, focussing on their socio-cultural dimension and seeing them as symptomatic of the current era of globalisation. Emerging viral threats exemplify the extent to which humans evolved into a global species, with a pervasive and irreversible impact on the planetary ecosystem. To effectively address these disruptive threats, an attitude of preparedness seems called for, not only on the viroscientific, but also on bioethical, regulatory and governance levels. This paper analyses the (...)

  21. The Depths of Temporal Desynchronization in Grief.Emily Hughes - 2022 - Psychopathology 55.
    Introduction: The experience of disconnection is common in first-person accounts of grief. One way in which this feeling of estrangement can manifest is through the splintering apart of the time of the mourner and the time of the world. Supplementing and extending Thomas Fuchs' influential idea of temporal desynchronization, my aim in this article is to give an account of the heterogeneous ways in which grief can disturb time. -/- Method: I organize these manifold experiences of temporal (...)

  22. Everettian Formulation of the Second Law of Thermodynamics.Yu Feng - manuscript
    The second law of thermodynamics is traditionally interpreted as a coarse-grained result of classical mechanics. Recently its relation with quantum mechanical processes such as decoherence and measurement has been revealed in literature. In this paper we will formulate the second law and the associated time irreversibility following Everett’s idea: systems entangled with an object getting to know the branch in which they live. Accounting for this self-locating knowledge, we get two forms of entropy: objective entropy measuring the uncertainty (...)

    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 (...)

    Grief research in philosophy agrees that one who grieves grieves over the irreversible loss of someone whom the griever loved deeply, and that someone thus factored centrally into the griever’s sense of purpose and meaning in the world.

I want to restrict my account to the paradigm case because the paradigm case most persuades the mind that grief (...)

Here we list all known ways to resurrect the dead that do not contradict our current scientific understanding of the world.

The most well-known such approach to technological resurrection is cryonics. Another (...)

Despite good legal practice and comprehensive guidelines, evidence suggests that Environmental Impact Assessment (EIA) or more broadly Environmental, Social and Health Impact Assessment (ESHIA) have not yet been found satisfactory in Nigeria, as the current system amounts to (...)

  43. Is Death Irreversible?Nada Gligorov - 2023 - Journal of Medicine and Philosophy 48 (5):492-503.
    There are currently two legally established criteria for death: the irreversible cessation of circulation and respiration and the irreversible cessation of neurologic function. Recently, there have been technological developments that could undermine the irreversibility requirement. In this paper, I focus both on whether death should be identified as an irreversible state and on the proper scope of irreversibility in the biological definition of death. In this paper, I tackle the distinction between the commonsense definition of death and the (...)

  44. Existential risk pessimism and the time of perils.David Thorstad - manuscript
    When our choice affects some other person and the outcome is unknown, it has been argued that we should defer to their risk attitude, if known, or else default to use of a risk avoidant risk function. This, in turn, has been claimed to require the use of a risk avoidant risk function when making decisions that primarily affect future people, and to decrease the desirability of efforts to prevent human extinction, owing to the significant risks associated with continued human (...)

  45. How to Change the Past in One-Dimensional Time.Roberto Loss - 2015 - Pacific Philosophical Quarterly 96 (1):1-11.
    The possibility of changing the past by means of time-travel appears to depend on the possibility of distinguishing the past as it is ‘before’ and ‘after’ the time-travel. So far, all the metaphysical models that have been proposed to account for the possibility of past-changing time-travels operate this distinction by conceiving of time as multi-dimensional, and thus by significantly inflating our metaphysics of time. The aim of this article is to argue that there is an (...)

  46. Branching time and doomsday.Giacomo Andreoletti - 2022 - Ratio 35 (2):79-90.
    Branching time is a popular theory of time that is intended to account for the openness of the future. Generally, branching-time models the openness of the future by positing a multiplicity of concrete alternative futures mirroring all the possible ways the future could unfold. A distinction is drawn in the literature among branching-time theories: those that make use of moment-based structures and those that employ history-based ones. In this paper, I introduce and discuss a particular kind (...)

  47. The Time Flow Manifesto CHAPTER 3 REVERSIBILTY IN PHYSICS.Andrew Holster - manuscript
    The conventional claims and concepts of 5* - 8* are a hang-over from the classical theory of thermodynamics – i.e. thermodynamics based on a fully deterministic micro-theory, developed in the time of Boltzmann, Loschmidt and Gibbs in the late C19th. The classical theory has well-known ‘reversibility paradoxes’ when applied to the universe as a whole. But the introduction of intrinsic probabilities in quantum mechanics, and its consequent time asymmetry, fundamentally changes the picture.

  48. From Time Asymmetry to Quantum Entanglement: The Humean Unification.Eddy Keming Chen - 2022 - Noûs 56 (1):227-255.
    Two of the most difficult problems in the foundations of physics are (1) what gives rise to the arrow of time and (2) what the ontology of quantum mechanics is. I propose a unified 'Humean' solution to the two problems. Humeanism allows us to incorporate the Past Hypothesis and the Statistical Postulate into the best system, which we then use to simplify the quantum state of the universe. This enables us to confer the nomological status to the quantum state (...)

  49. Can Things Endure in Tenseless Time.Rögnvaldur Ingthorsson - 2009 - SATS 10 (1):79-99.
    It has been argued that the tenseless view of time is incompatible with endurantism. This has been disputed, perhaps most famously by Hugh Mellor and Peter Simons. They argue that things can endure in tenseless time, and indeed must endure if tenseless time is to contain change. In this paper I will point out some difficulties with Mellor’s and Simons’ claims that in tenseless time a particular can be ‘wholly present’ at various times, and therefore endure, (...)
