  1. 5 Bizarre Paradoxes Of Time Travel Explained

    1: Predestination Paradox. A Predestination Paradox occurs when the actions of a person traveling back in time become part of past events, and may ultimately cause the event he is trying to prevent to take place. The result is a 'temporal causality loop' in which Event 1 in the past influences Event 2 in the future (time travel to the past ...

  2. Temporal paradox

    A temporal paradox, time paradox, or time travel paradox, is a paradox, an apparent contradiction, or logical contradiction associated with the idea of time travel or other foreknowledge of the future. While the notion of time travel to the future complies with the current understanding of physics via relativistic time dilation, temporal paradoxes arise from circumstances involving ...

  6. Time Travel and Modern Physics

    First published Thu Feb 17, 2000; substantive revision Mon Mar 6, 2023. Time travel has been a staple of science fiction. With the advent of general relativity it has been entertained by serious physicists. But, especially in the philosophy literature, there have been arguments that time travel is inherently paradoxical.

  7. Is time travel even possible? An astrophysicist explains the science

  12. There's One Way Time Travel Could Be Possible, According to This

    Eliminating the paradoxes. There's a common misconception in science fiction that paradoxes can be "created." Time travellers are usually warned not to make significant changes to the past and to avoid meeting their past selves for this exact reason. Examples of this may be found in many time travel movies, such as the Back to the Future trilogy.

  13. Paradoxes of Time Travel

    Abstract. Paradoxes of Time Travel is a comprehensive study of the philosophical issues raised by the possibility of time travel.

  15. Time travel paradoxes and multiple histories

    If time travel is possible, it seems to inevitably lead to paradoxes. These include consistency paradoxes, such as the famous grandfather paradox, and bootstrap paradoxes, where something is created out of nothing. One proposed class of resolutions to these paradoxes allows for multiple histories (or timelines) such that any changes to the past occur in a new history, independent of the one ...

  16. How many types of paradoxes are there in time travel and what ...

    There are a lot of paradoxes associated with time travel but my favourite is the predestination paradox in which a person goes back in the past and gets involved in an event to alter the future but instead, that results in that event being fulfilled and you were the soul reason for this endless cycle.

  19. New Brock research explores time travel paradoxes

    Another possible way to resolve time travel paradoxes is by assuming the existence of multiple histories (or timelines). In this scenario, travelling back in time causes history to split into two independent histories: the original one and a new one. In the original history, Alice was born. In the new history, Alice was not born.
