    Can We Describe Possible Circumstances in Which We Would Have.Graham Oppy - 2004 - Ratio 17 (1):68-83.
    This paper investigates the question whether we could have reason to believe that time is two-dimensional. I connect discussion of this question to discussion of the question whether we could have reason to believe that there has been a global time freeze.

    Filosofia călătoriei în timp – Paradoxul bunicului.Nicolae Sfetcu - manuscript
    Newton a susținut ideea timpului absolut, spre deosebire de Leibniz pentru care timpul este doar o relație între evenimente și nu poate fi exprimat în mod independent, afirmație în concordanță ci relativitatea spațiu-timpului. Eternismul susține că trecutul și viitorul există într-un sens real, mergându-se până la ideea că timpul este o dimensiune similară cu dimensiunile spațiale, că evenimentele viitoare și trecute sunt "prezente" pe axa timpului, dar această opinie este contestată. Cel mai cunoscut exemplu de imposibilitate a călătoriei în timp (...)

    Teleportative Observers Versus Special Relativity Observers: The Logical Universal Chronology and Presentism.James Goetz - manuscript
    Various authors use the Rietdijk–Putnam argument while proposing that special relativity implies eternalism. For example, special relativity observers are limited by the relativity of simultaneity and cannot detect a preferred universal chronology. Any pair of special relativity observers that are causally disconnected to each other will detect ubiquitous relativistic reversals of chronology. The argument concludes that the reversals of chronology imply that all events in the past, present, and future exist "now." However, I introduce "teleportative observers" which cohere with wormhole (...)

    A Blast From The Past.Kristie Miller - 2017 - The Philosophers' Magazine 77:82-86.
    That we find the idea of travelling in time, and in particular travelling backwards in time, fascinating, is evidenced by the plethora of new science fictions shows depicting time travel that hit our TV screens in 2016. I love time travel shows, and I can hardly keep up. In almost all cases these shows depict what philosophers call inconsistent time travel stories: stories that commit what my colleague Nick Smith (The University of Sydney) calls the second time around fallacy. These (...)

    Călătoria în timp.Nicolae Sfetcu - manuscript
    Călătoria în timp implică deplasarea într-un timp diferit de cel prezent, în trecut sau în viitor, în principiu fără o deplasare în spațiu cu referire la un sistem de coordonate local. Călătoria în timp poate fi făcută de un corp material care poate fi sau nu o ființă vie, și pentru care se folosește de obicei un dispozitiv special denumit mașina timpului. Călătoria în timp este un concept recunoscut în filosofie și știință, dar a cărui posibilitatea este foarte disputată, dând (...)

    Space, Time, and Time Travel.Nicolae Sfetcu - manuscript
    Newton supported the idea of absolute time, unlike Leibniz, for which time is only a relation between events and cannot be expressed independently, a statement in concordance with the relativity of space-time. Eternalism claims that the past and the future exist in a real sense, going to the idea that time is a dimension similar to spatial dimensions, that future and past events are "present" on the axis of time, but this view is challenged. On four-dimensional vision, the universe is (...)

    Grandfather Paradox in Time Travel.Nicolae Sfetcu - manuscript
    The most well-known example of the impossibility of traveling in time is the grandfather paradox or self-infanticide argument: a person who travels in the past and kills his own grandfather, thus preventing the existence of one of his parents and thus his own existence. A philosophical response to this paradox would be the impossibility of changing the past, like Novikov self-consistency principle (if an event exists that would cause a paradox or any "change" to the past whatsoever, then the probability (...)

    Time Travel.Nicolae Sfetcu - manuscript
    Time travel is a recognized concept in philosophy and science, but whose scope is highly disputed, giving rise to numerous paradoxes in both philosophy and science. Time travel is considered by some accepted both in general relativity and quantum mechanics, but there is a unanimous consensus that it is not feasible with current technology. (Hawkins 2010) The raised issues are different for the time travel in the past compared to the time travel in the future.

    The End of Mystery.Sam Baron & Mark Colyvan - forthcoming - American Philosophical Quarterly.
    Tim travels back in time and tries to kill his grandfather before his father was born. Tim fails. But why? Lewis’s response was to cite ‘coincidences’: Tim is the unlucky subject of gun jammings, banana peels, sudden changes of heart and so on. A number of challenges have been raised against Lewis’s response. The latest of these focuses on explanation. This paper diagnoses the source of this new disgruntlement and offers an alternative explanation for Tim’s failure, one that Lewis would (...)

    Time Travel and the Immutability of the Past Within B-Theoretical Models.Giacomo Andreoletti & Giuliano Torrengo - forthcoming - Philosophia:1-11.
    The goal of this paper is to defend the general tenet that time travelers cannot change the past within B-theoretical models of time, independently of how many temporal dimensions there are. Baron (2017) offered a strong argument intended to reach this general conclusion. However, his argument does not cover a peculiar case, i.e. a B-theoretical one-dimensional model of time that allows for the presence of internal times. Loss (2015) used the latter model to argue that time travelers can change the (...)

    Two Arguments From Sider’s Four-Dimensionalism. [REVIEW]Ned Markosian - 2004 - Philosophy and Phenomenological Research 68 (3):665–673.
    In this essay for a PPR book symposium on Theodore Sider's _Four-Dimensionalism<D>, I focus on two of Sider's arguments for four-dimensionalism: (i) his argument from vagueness, and (ii) his argument from time travel. Concerning (i), I first show that Sider's argument commits him to certain strange consequences that many four-dimensionalists may not endorse, and then I discuss an objection that involves appealing to 'brutal composition', the view that there is no informative answer to Peter van Inwagen's 'special composition question'. Concerning (...)

    Do Cry Over Spilt Milk: Possibly You Can Change the Past.Peter B. M. Vranas - 2005 - The Monist 88 (3):370-387.
    There is widespread agreement, even among those who accept the possibility of backward causation, that it is impossible to change the past. I argue that this agreement corresponds to a relatively uninteresting understanding of what changing the past amounts to. In one sense it is indeed impossible to change the past: in no possible world is an action performed which makes the past in that world different from the past in that world. In another sense, however, it may be possible (...)

    If Time Travel to Our Location is Possible, We Do Not Live in a Branching Universe.James Norton - 2018 - Analysis 78 (2):260-266.
    This paper argues for the following disjunction: either we do not live in a world with a branching temporal structure, or backwards time travel is nomologically impossible, given the initial state of the universe, or backwards time travel to our space-time location is impossible given large-scale facts about space and time. A fortiori, if backwards time travel to our location is possible, we do not live in a branching universe.

    Is Some Backwards Time Travel Inexplicable?Kristie Miller - 2017 - American Philosophical Quarterly 54 (2):131-141.
    It has been suggested that there is something worrisome, puzzling, or incomprehensible about the sorts of causal loops sometimes involved in backwards time travel. This paper disentangles two distinct puzzles and evaluates whether they provide us reason to find backwards time travel incomprehensible, inexplicable, or otherwise worrisome. The paper argues that they provide no such reason.

The complexity and the contradictory nature this subject makes it difficult to be more precise about "time". On its deepest subjective side, time is a means of perception, a biological rhythm, a social phenomenon in terms of our collective understanding of (...)

    The Metaphysics of Mortals: Death, Immortality, and Personal Time.Cody Gilmore - 2016 - Philosophical Studies 173 (12):3271-3299.
    Personal time, as opposed to external time, has a certain role to play in the correct account of death and immortality. But saying exactly what that role is, and what role remains for external time, is not straightforward. I formulate and defend accounts of death and immortality that specify these roles precisely.

    Nowhere Man: Time Travel and Spatial Location.Sara Bernstein - 2015 - Midwest Studies in Philosophy 39 (1):158-168.
    This paper suggests that time travelling scenarios commonly depicted in science fiction introduce problems and dangers for the time traveller. If time travel takes time, then time travellers risk collision with past objects, relocation to distant parts of the universe, and time travel-specific injuries. I propose several models of time travel that avoid the dangers and risks of time travel taking time, and that introduce new questions about the relationship between time travel and spatial location.

    In this chapter I articulate the threat that time travel to the past allegedly poses to the free will of the time traveler, and I argue that on the traditional way of thinking about free will, the incompatibilist about time travel and free will wins the day. However, a residual worry about the incompatibilist view points the way toward a novel way of thinking about free will, one that I tentatively explore toward the end of the chapter.

    The Apparent Nature of Relative Simultaneity.Andrew Wutke - manuscript
    This paper presents the proof of the apparent nature of relative simultaneity originally derived from Einstein’s Special Theory of Relativity (STR). The proof does not challenge the validity of the STR but uncovers fundamental and widespread error in understanding of practical implications of Lorentz transformations. It is demonstrated that more than a century long debates generally miss the point. This results in counterintuitive claims of coexisting multiple time realities by mere equivalence of equal clock indications and simultaneity. Such claims have (...)

    Travelling in Time: How to Wholly Exist in Two Places at the Same Time.Kristie Miller - 2006 - Canadian Journal of Philosophy 36 (3):309-334.
    It is possible to wholly exist at multiple spatial locations at the same time. At least, if time travel is possible and objects endure, then such must be the case. To accommodate this possibility requires the introduction of a spatial analog of either relativising properties to times—relativising properties to spatial locations—or of relativising the manner of instantiation to times—relativising the manner of instantiation to spatial locations. It has been suggested, however, that introducing irreducibly spatially relativised or spatially adverbialised properties presents (...)

I will show that some unusual claims of the Real Presence doctrine exactly parallel what would be happening in the world if objects were to time-travel in certain ways. Such time-travel would make ordinary objects multiply located, and in the relevantly analogous respects. If it is conceptually coherent that objects behave in this way, we have a model for (...)

    Presentist Time Travel and the Limits of Presentist Causality.David Pensgard - 2001 - Philosophy 79 (3):333-345.
    A recent account of presentist time travel involves a causal relation between events at two different and discontiguous times, and presentists cannot have such causal relations because presentism rules out the existence of at least one of the two relata in such a relation due to it being non-present. Additionally, presentists cannot have parodies of such causal relations for use in time travel stories because parodies are subject, at least, to the same limitations as the things being parodied. So, the (...)

    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 intuitive sense in which past-changing (...)

    Occupy Wall: A Mereological Puzzle and the Burdens of Endurantism.Paul Richard Daniels - 2014 - Australasian Journal of Philosophy 92 (1):91-101.
    Endurantists have recently faced a mereological puzzle in various forms. Here I argue that, instead of presenting a genuine worry, the puzzle actually reveals a common misunderstanding about the endurantist ontology. Furthermore, through this discussion of the alleged problem and the misunderstanding which motivates it, I reveal metaphysical commitments the endurantist has that may not be widely recognized. For instance, she is committed to interesting and perhaps controversial views about shape and location. I highlight these commitments and what they mean (...)

It has been relatively uncontroversial until recently to hold that presentism is inconsistent with the possibility of time travel. I argue that recent arguments to the contrary do not show that presentism is consistent with time travel. Moreover, the necessary truth of other open future-objective present models which we (...)

    What Time Travelers Cannot Not Do (but Are Responsible for Anyway).Joshua Spencer - 2013 - Philosophical Studies 166 (1):149-162.
    The Principle of Alternative Possibilities is the intuitive idea that someone is morally responsible for an action only if she could have done otherwise. Harry Frankfurt has famously presented putative counterexamples to this intuitive principle. In this paper, I formulate a simple version of the Principle of Alternative Possibilities that invokes a course-grained notion of actions. After warming up with a Frankfurt-Style Counterexample to this principle, I introduce a new kind of counterexample based on the possibility of time travel. At (...)

    Thinking about time travel is an entertaining way to explore how to understand time and its location in the broad conceptual landscape that includes causation, fate, action, possibility, experience, and reality. It is uncontroversial that time travel towards the future exists, and time travel to the past is generally recognized as permitted by Einstein’s general theory of relativity, though no one knows yet whether nature truly allows it. Coherent time travel stories have added flair to traditional debates over the metaphysical (...)

    Do the Laws of Physics Forbid the Operation of Time Machines?John Earman, Chris Smeenk & Christian Wüthrich - 2009 - Synthese 169 (1):91 - 124.
    We address the question of whether it is possible to operate a time machine by manipulating matter and energy so as to manufacture closed timelike curves. This question has received a great deal of attention in the physics literature, with attempts to prove no- go theorems based on classical general relativity and various hybrid theories serving as steps along the way towards quantum gravity. Despite the effort put into these no-go theorems, there is no widely accepted definition of a time (...)

    Paradoxes and Hypodoxes of Time Travel.Peter Eldridge-Smith - 2007 - In Jan Lloyd Jones, Paul Campbell & Peter Wylie (eds.), Art and Time. Australian Scholarly Publishing. pp. 172--189.
    I distinguish paradoxes and hypodoxes among the conundrums of time travel. I introduce ‘hypodoxes’ as a term for seemingly consistent conundrums that seem to be related to various paradoxes, as the Truth-teller is related to the Liar. In this article, I briefly compare paradoxes and hypodoxes of time travel with Liar paradoxes and Truth-teller hypodoxes. I also discuss Lewis’ treatment of time travel paradoxes, which I characterise as a Laissez Faire theory of time travel. Time travel paradoxes are impossible according (...)

    Time Travel and Time Machines.Chris Smeenk & Christian Wuthrich - 2009 - In Craig Callender (ed.), The Oxford Handbook of Philosophy of Time. Oxford: Oxford University Press. pp. 577-630.
    This paper is an enquiry into the logical, metaphysical, and physical possibility of time travel understood in the sense of the existence of closed worldlines that can be traced out by physical objects. We argue that none of the purported paradoxes rule out time travel either on grounds of logic or metaphysics. More relevantly, modern spacetime theories such as general relativity seem to permit models that feature closed worldlines. We discuss, in the context of Gödel's infamous argument for the ideality (...)

    What Time Travelers May Be Able to Do.Peter B. M. Vranas - 2010 - Philosophical Studies 150 (1):115 - 121.
    Kadri Vihvelin, in "What time travelers cannot do" (Philos Stud 81: 315-330, 1996), argued that "no time traveler can kill the baby who in fact is her younger self, because (V1) "if someone would fail to do something, no matter how hard or how many times she tried, then she cannot do it", and (V2) if a time traveler tried to kill her baby self, she would always fail. Theodore Sider (Philos Stud 110: 115-138, 2002) criticized Vihvelin's argument, and Ira (...)

    Can I Kill My Younger Self? Time Travel and the Retrosuicide Paradox.Peter B. M. Vranas - 2009 - Pacific Philosophical Quarterly 90 (4):520-534.
    If time travel is possible, presumably so is my shooting my younger self ; then apparently I can kill him – I can commit retrosuicide. But if I were to kill him I would not exist to shoot him, so how can I kill him? The standard solution to this paradox understands ability as compossibility with the relevant facts and points to an equivocation about which facts are relevant: my killing YS is compossible with his proximity but not with his (...)

    Location and Perdurance.Antony Eagle - 2010 - In Dean Zimmerman (ed.), Oxford Studies in Metaphysics: Volume 5. Oxford Univerity Press. pp. 53-94.
    Recently, Cody Gilmore has deployed an ingenious case involving backwards time travel to highlight an apparent conflict between the theory that objects persist by perduring, and the thesis that wholly coincident objects are impossible. However, careful attention to the concepts of location and parthood that Gilmore’s cases involve shows that the perdurantist faces no genuine objection from these cases, and that the perdurantist has a number of plausible and dialectically appropriate ways to avoid the supposed conflict.

    Time Travel Without Causal Loops.Bradley Monton - 2009 - Philosophical Quarterly 59 (234):54-67.
    It has sometimes been suggested that backwards time travel always incurs causal loops. I show that this is mistaken, by describing worlds where backwards time travel occurs and yet no causal loops occur. Arguments that backwards time travel can occur without causal loops have been given before in the literature, but I show that those arguments are unconvincing.
