Time Travel = Infinite Harry Potter's ?

Click For Summary

Discussion Overview

The discussion centers around the concept of time travel, using a scenario from J.K. Rowling's "Prisoner of Azkaban" as a backdrop. Participants explore the implications of time travel on identity and the potential for infinite iterations of a character, specifically in the context of Harry Potter. The conversation touches on theoretical aspects of time travel and its representation in popular culture.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions whether the scenario of multiple Harrys leads to an infinite loop of iterations, suggesting a paradox in time travel.
  • Another participant expresses skepticism about the physics relevance of the topic, indicating it may be more suitable for general discussion rather than a physics-focused forum.
  • A participant mentions that time travel was discussed in their Advanced Placement Physics class, implying a connection to physics despite the skepticism.
  • One participant proposes that replacing "Harry Potter" with "fermionic particle" could lead to a more interesting physical question, hinting at the potential for deeper scientific exploration.
  • Another participant adds that the discussion would be even more interesting if a boson were involved, suggesting a preference for exploring particle physics in relation to time travel.

Areas of Agreement / Disagreement

Participants express differing views on the relevance of the topic to physics, with some questioning its suitability for discussion in a physics forum while others see potential for theoretical exploration. No consensus is reached regarding the validity of the time travel scenario as a physics question.

Contextual Notes

Participants do not fully agree on the applicability of time travel to physics, and there are unresolved assumptions about the nature of time travel and its implications. The discussion remains speculative without definitive conclusions.

Time Travel = Infinite Harry Potter's ?

This contains a Harry Potter *SPOILER*

...but I'm using it as a background for a question about Time Travel in general.

In J.K. Rowling's book, "Prisoner of Azkaban" when Harry is surrounded by dementors, he suddenly sees a stranger who looks eerily similar to him. The stranger then casts a spell that drives the dementors away.

Harry then goes into his school where he is given a device that could make him go back in time. He then goes back in time where he sees his past self surrounded by dementors. He then casts a spell that drives the dementors away.

Okay, I don't care about the rest of the book. My focus now is about Time Travel in general.

Now we have three Harry's. Present Harry who was saved by future Harry (the stranger who looked eerily similar to him) and then present Harry went back in time and saved past Harry.

1) Wouldn't this lead to infinite Harrry's since he's stuck in this loop of sorts ?


So if we managed to go back in time, how would we resolve this issue ?

Or maybe there's something wrong with my reasoning :shy:

I don't see any possibility for a discussion based on physics for this topic. But it sure might be fun else where. So off to GD and thread hungry hoards.

I posted it in the physics forum because we discussed Time travel to a great extent in my Advanced Placement Physics class.

I think that if we replaced "Harry Potter" with "fermionic particle", this would be an interesting physical question. :smile:

'twould be more interesting with a boson.
 
'twould make more sense...
