Time Travel = Infinite Harry Potter's ?

AI Thread Summary
The discussion centers on the concept of time travel as illustrated in J.K. Rowling's "Prisoner of Azkaban," where Harry Potter encounters a future version of himself who saves him from dementors. This scenario raises the question of whether such time travel could result in an infinite loop of Harrys, as each version saves the other, creating a paradox. Participants ponder the implications of this loop and its resolution, suggesting that if the characters were replaced with particles, it could lead to a more scientifically interesting discussion. The conversation highlights the complexities and potential contradictions of time travel, while acknowledging the lack of a solid physics framework to address these issues.

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:

Thread 'Predictions for the Nobel Prize in Physics 2025'

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...

Thread 'My experience as a hostage'

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
