Time Travel

About this topic
| Summary | The philosophy of time travel involves investigation into the question of the physical, logical and metaphysical possibility of time travel. The topic centres on the fact that time travel scenarios seem physically possible, and yet many counterexamples have been put forward showing that it is not logically possible. The famous grandfather paradox asks whether it is possible for one to travel backwards in time to kill their own grandfather. The problem here is that, while it seems possible to engage in backwards time travel, it also seems impossible to change the past. Standard solutions to the paradox have interesting consequences for issues surrounding free will, as the thought goes that some event would always prevent a time traveller from doing the impossible and changing the past. However, without an explanation as to why a time traveller is prevented from performing certain actions this solution has been thought by some to be untenable. An alternative proposed solution, then, is that time is two-dimensional, and that it is possible to change the past on one of these temporal dimensions. Another, related, topic in the literature is that time travel involves backwards causation and, therefore, causal loops. There are two things at issue here. The first is the dispute between those who think that time travel entails causal loops and those who do not. And the second is the dispute between those who think that time travel does entail causal loops and that this is problematic and those who agree with the entailment but argue that it is not problematic. Additional issues in the time travel literature involve time travel and temporal ontology – i.e., whether or not the past, present and future are necessary for time travel – and time travel and identity over time – i.e., whether or not certain views of the persistence of objects rule out the possibility of the same object having two incompatible properties at the same time (due to a time-traveller encountering their younger self). |
| Key works | Classic works on the grandfather paradox are Lewis 1976 and Horwich 1975. Lewis's solution to the grandfather paradox is defended against Horwich 1975 by Smith 1997 and Dowe 2003. The relationship between the grandfather paradox and free will is discussed in Sider 2002 and Vihvelin 1996. Riggs 1997 argues against the solution to the paradox whereby the time traveller is prevented from performing certain actions is untenable, and Baron 2017 looks at the two-dimensional solution to the paradox. Bernstein 2017 discusses time travel and the movable present. A solution to Einstein's field equations that permits closed time-like curves is given in Gödel 1949. Closed time-like curves are discussed in Dowe 2007. The compatibility between dynamic theories of time and time travel is discussed in Monton 2003, Miller 2005, Miller 2006, Miller 2006, Dowe 2009 and Sider 2005. Miller 2021 looks at time travel and future-bias. |

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.

- Time Travel.Nicolae Sfetcu - manuscriptTime 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.
- Grandfather paradox in time travel.Nicolae Sfetcu - manuscriptThe 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 (...)

- La causalité dans le voyage dans le temps.Nicolae Sfetcu - manuscriptCertains scientifiques et philosophes sont d’avis que toute théorie permettant un voyage dans le temps introduirait des problèmes de causalité. Ces types de paradoxes temporels peuvent être évités grâce au principe de cohérence de Novikov ou à une variation de l'interprétation des mondes multiples avec des mondes en interaction. L'argument classique contre la causalité rétrograde est l'argument du contournement. La causalité implique un avenir ontologiquement fermé - une position métaphysique sur le temps communément appelée l'éternalisme, une forme spécifique de non-présentisme. (...)

Dans la vision à quatre dimensions, l'univers est une topologie espace-temps existante, contenant tout ce qui s'est passé, tout ce qui se passe et tout ce qui va se passer.

Argumentul clasic împotriva cauzalității înapoi este argumentul bilking, Dacă un eveniment A provoacă un eveniment anterior B, bilking recomandă o încercare de a decorela A și B, adică de a aduce A în cazurile în care B nu a avut loc și de a (...)

- Back to the Future: Curing Past Sufferings and S-Risks via Indexical Uncertainty.Alexey Turchin - manuscriptThe long unbearable sufferings in the past and agonies experienced in some future timelines in which a malevolent AI could torture people for some idiosyncratic reasons (s-risks) is a significant moral problem. Such events either already happened or will happen in causally disconnected regions of the multiverse and thus it seems unlikely that we can do anything about it. However, at least one pure theoretic way to cure past sufferings exists. If we assume that there is no stable substrate of (...)
- The Apparent Nature of Relative Simultaneity.Andrew Wutke - manuscriptThis 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 (...)

So as not to beg any questions, let us label what is sitting B and what is standing C.

- Mourning a death foretold: memory and mental time travel in anticipatory grief.Christopher Jude McCarroll & Karen Yan - forthcoming - Phenomenology and the Cognitive Sciences:1-19.Grief is a complex emotional experience or process, which is typically felt in response to the death of a loved one, most typically a family member, child, or partner. Yet the way in which grief manifests is much more complex than this. The things we grieve over are multiple and diverse. We may grieve for a former partner after the breakup of a relationship; parents sometimes report experiencing grief when their grown-up children leave the family home. We can also experience (...)

We take our cue from a recent paper by Yishai Cohen, who argues that if time travel is metaphysically possible, then one of the most influential theories of moral responsibility (i.e., Fischer and Ravizza’s) is false. We argue that Cohen’s argument is unsound but that Cohen’s argument can serve as a lens to bring reasons-responsive theories of moral responsibility into sharper focus, helping us to better (...)

Philosophy of Time: The Basics doesn’t answer these questions. It does give you an opinionated introduction to thinking a bit more deeply about them. Written in a way that assumes no philosophical background from its readers, this book looks at central topics in philosophy of time and shows how they relate to other time-related topics – from theoretical physics (without the maths!) to your own mortality. Additional (...)

Many have thought that these kinds of decisions pose a distinctive and novel problem for causal decision theory (CDT). My thesis is that foreknowledge poses no new problems for CDT. Some of the purported problems are not problems. Others are problems, but they are not problems for CDT. Rather, they are problems for our theories of subjunctive supposition. Others are problems, but they are (...)

There are also possible worlds in which time is linear and infinite in both directions and in which history is repetitive, consisting of infinitely many 12,000-year epochs, each two of which are exactly alike with respect to all intrinsic, purely qualitative properties. Could one ever have empirical evidence that one inhabits a world of the first kind rather than a world (...)
- Mental Time Travel in Animals: The “When” of Mental Time Travel.Andrew J. Latham, Kristie Miller & Rasmus Pedersen - 2024 - Philosophical Transactions of the Royal Society B: Biological Sciences 379 (1913).While many aspects of cognition have been shown to be shared between humans and non-human animals, there remains controversy regarding whether the capacity to mentally time travel is a uniquely human one. In this paper, we argue that there are four ways of representing when some event happened: four kinds of temporal representation. Distinguishing these four kinds of temporal representation has five benefits. First, it puts us in a position to determine the particular benefits these distinct temporal representations afford an (...)
- Meaning, Metalepsis, Time-Travel.Glenn Mackin - 2024 - Res Philosophica 101 (2):299-322.This article explores how people can come to experience constitutional conversations as meaningful. To this end, I reinterpret Habermas’s account of deliberative constitutionalism. For Habermas, constitutional discourses are not only rational procedures of opinion- and will-formation, but also sites at which a “world” gets generated. Deliberative politics, therefore, involves unruly and uncontrollable efforts to solicit others into the roles, orientations, and principles of constitutional practices. The result is a novel account of the relationship between constitutional procedures and the “anarchistic” politics (...)
- The Future of the Present.Ulrich Meyer - 2024 - Erkenntnis 89:463-478.Some theories of time entail that the present can change before or after it has happened. Examples include views on which time-travelers can change the past, the glowing block theory, Peter Geach’s mutable future view, and the moving spotlight theory. This paper argues that such ante factum or posthumous change requires a heterodox “split time” view on which earlier-than is not the converse of later-than.
- Mental time-travel, semantic flexibility, and A.I. ethics.Marcus Arvan - 2023 - AI and Society 38 (6):2577-2596.This article argues that existing approaches to programming ethical AI fail to resolve a serious moral-semantic trilemma, generating interpretations of ethical requirements that are either too semantically strict, too semantically flexible, or overly unpredictable. This paper then illustrates the trilemma utilizing a recently proposed ‘general ethical dilemma analyzer,’ GenEth. Finally, it uses empirical evidence to argue that human beings resolve the semantic trilemma using general cognitive and motivational processes involving ‘mental time-travel,’ whereby we simulate different possible pasts and futures. I (...)
- A Long Time Ago? Time and Time Travel in Star Wars.Philipp Berghofer - 2023 - In Jason T. Eberl & Kevin S. Decker (eds.), Star Wars and Philosophy Strikes Back. Hoboken, NJ: Wiley. pp. 99–107.This chapter introduces time travel into the Star Wars lore. Time travel stories in which the past is changed are in danger of being inconsistent or plagued by paradoxes. In famous time travel stories such as Back to the Future, the protagonist travels to the past, changes the past, and then returns to a present quite different from the one they left. In contemporary philosophy of time, there are three main approaches to this question: presentism, eternalism, and the growing block (...)
- An inexplicably good argument for causal finitism.Ibrahim Dagher - 2023 - International Journal for Philosophy of Religion 94 (2):199-211.Causal finitism, the view that the causal history of any event must be finite, has garnered much philosophical interest recently—especially because of its applicability to the Kalām cosmological argument. The most prominent argument for causal finitism is the Grim Reaper argument, which attempts to show that, if infinite causal histories are possible, then other paradoxical states of affairs must also be possible. However, this style of argument has been criticized on the grounds of (i) relying on controversial modal principles, and (...)

First, I discuss what type of possibility we might have in mind, detailing ‘close possibility’ as one such candidate. Secondly, I argue that—with only little exception—these more outlandish tropes fail to be closely possible. Thirdly, I discuss whether these outlandish tropes may nevertheless be more broadly (...)

- The Logic of Past-Alteration.Alex Kaiserman - 2023 - In Karen Bennett & Dean W. Zimmerman (eds.), Oxford Studies in Metaphysics Volume 13. Oxford, GB: Oxford University Press. pp. 283-314.Is it possible to change the past—to make something that has happened not have happened? Past-alteration is widely believed to be ‘logically impossible’. But despite this, there have been few attempts to actually apply logical resources to the question of whether it is possible to change the past. This chapter articulates a novel tense logic and uses it to argue that past-alteration is possible—with just a single dimension of time—so long as it’s possible for time to have a certain kind (...)
- A Comparative Analysis of David Lewis' Modal Realism and Everett's Many Worlds on Closed Time-like Curves and Time Travel.Fabian Kerj - 2023 - Dissertation, King's College LondonThis paper explores the physical and metaphysical implications of time travel, focusing on the possibility of changing the past, through a comparative analysis of David Lewis' modal realism and Everett's many-worlds interpretation of quantum mechanics. The existence of closed timelike curves (CTCs) in certain solutions to Einstein's field equations provides a theoretical basis for the possibility of backwards time travel, but this leads to a range of paradoxes, most notably the grandfather paradox. David Lewis argues that time travel must maintain (...)
- Time Travel and Collisions.Cei Maslen - 2023 - Metaphysica 24 (2):407-419.This paper focuses on problems for time travel that specifically concern continuous time-travel to the past, problems to do with potential collisions with past obstacles such as former time-slices of the time traveler herself. These problems have not been discussed nearly as much as other questions about time travel, such as the Grandfather Paradox. Here I focus on discussions by Bernstein, Dowe, Grey and Le Poidevin. After examination, I conclude that only the problems of turning around in time have any (...)
- The Eucharist according to Gunk-relational Ontology.Damiano Migliorini - 2023 - Münchener Theologische Zeitschrift 74 (3):315-330.The rational explanation of the Eucharist is at the centre of a revived debate in philosophical theology. After describing gunk-relational ontology, I show how it allows us to understand transubstantiation differently than other traditional and contemporary accounts, from which it draws a few points but combining them in a new way. In gunk-relational ontology every substance is its own relations, which constitute a gunky fundamental reality. The liturgical celebration of the Last Supper therefore creates a new relational situation for the (...)
- Determinism, Counterfactuals, and the Possibility of Time Travel.Kadri Vihvelin - 2023 - Philosophies 8 (4):68.The Consequence argument is an argument from plausible premises–our lack of causal power over the laws and past–to an implausible conclusion: that if determinism is true, we are equally powerless with respect to the future. What the compatibilist needs is a theory of counterfactuals that preserves the links between counterfactuals, causation, and the natural laws in a way that supports our commonsense belief that we have the power to make a causal difference to the future but no such power with (...)
- Superdeterminism: a reappraisal.Giacomo Andreoletti & Louis Vervoort - 2022 - Synthese 200 (5):1-20.This paper addresses a particular interpretation of quantum mechanics, i.e. superdeterminism. In short, superdeterminism i) takes the world to be fundamentally deterministic, ii) postulates hidden variables, and iii) contra Bell, saves locality at the cost of violating the principle of statistical independence. Superdeterminism currently enjoys little support in the physics and philosophy communities. Many take it to posit the ubiquitous occurrence of hard-to-digest conspiratorial and coincidental events; others object that violating the principle of statistical independence implies the death of the (...)
- Paradoxes of Time Travel to the Future.Sara Bernstein - 2022 - In Helen Beebee & A. R. J. Fisher (eds.), Perspectives on the Philosophy of David K. Lewis. Oxford: Oxford University Press.This paper brings two fresh perspectives on Lewis’s theory of time travel. First: many key aspects and theoretical desiderata of Lewis’s theory can be captured in a framework that does not commit to eternalism about time. Second: implementing aspects of Lewisian time travel in a non-eternalist framework provides theoretical resources for a better treatment of time travel to the future. While time travel to the past has been extensively analyzed, time travel to the future has been comparatively underexplored. I make (...)
- Resisting temptation and overcoming procrastination: The roles of mental time travel and metacognition.Erica Cosentino, Christopher Jude McCarroll & Kourken Michaelian - 2022 - Phenomenology and the Cognitive Sciences 21 (4):791-811.We tend to seek immediate gratification at the expense of long-term reward. In fact, the more distant a reward is from the present moment?the more we tend to discount it. This phenomenon is known as temporal discounting. Engaging in mental time travel plausibly enables subjects to overcome temporal discounting, but it is unclear how, exactly, it does so. In this paper, we develop a framework designed to explain the effects of mental time travel on temporal discounting by showing how the (...)
- How Stable Is Objective Chance?John Cusbert - 2022 - British Journal for the Philosophy of Science 73 (3):613-629.This paper examines the stability of objective chance. I defend the stable chance thesis : that in any given possible world, any pair of intrinsic duplicate physical setups with the same chances of being subject to the same external influences must yield the same chances. I argue that SCT compares favourably to rivals in the literature. I then consider a challenge to SCT involving time travel and causal loops. I argue that SCT survives this challenge, but that such cases expose (...)
- Doctor Who as Philosophy: Four-Dimensionalism and Time Travel.Kevin S. Decker - 2022 - In David Kyle Johnson (ed.), The Palgrave Handbook of Popular Culture as Philosophy. Palgrave-Macmillan. pp. 135-161.Doctor Who is the longest-running science fiction program on television, having been in continuous production between 1963 and 1989. “Classic” Doctor Who was widely syndicated around the world and appeared to many US viewers on their local Public Broadcasting System channel. The show was rebooted with continuity to the original program on BBC One in 2005. The success of the show rests on the appeal of its central character and his/her traveling companions, the creativity of its bizarre locations and alien (...)
- Condillac and Derrida: Perception, the Human and Empiricism.Sean Gaston - 2022 - Research in Phenomenology 52 (1):1-22.In June 2020, a new work by Derrida on Condillac was published, Le Calcul des langues. This article re-examines Derrida’s readings of Condillac, focusing on the relation between perception and the language of signs; the relation between human knowledge and the animal; and the idealization and limits of empiricism.
