Temporal anomaly

[Darwinian]

Here's weird thing..

Currently watching Harry Potter and while in Hagrid's home, Hermione was struck by a carved pebble which she then put into her pocket. Later on she went back in time and threw that same pebble at her earlier self who, as we now, picked up the pebble and put it in her pocket only to later go back in time.. etc. etc..

Questions:

- If the pebble existed prior to Hermione putting it in her pocket, where did it come from?
- And if it constantly gets taken back in time to be thrown then has it, from the reference point of the time after they traveled to the past, simply ceased to exist?
- Is it destined to only ever exist within that 2 hour period of time, looping over and over again?
- Did it ever have a beginning and will it ever have an end?
- The fact that the pebble is destined to be thrown at a young girl for the rest of its own lifetime must mean that it will eventually wear away to nothing. How will this affect that part of history as the past must be gradually changing everytime that pebble is thrown?

That actually ruined that movie for me. Time travel in a movie (book, etc.) never works if you actually take the time to think about it. Probably due to time travel not being possible in reality.

I thought she picked up the pebble from the ground. Now I have to go dig out that movie and watch it. Is it Prisoner of Azkaban that happens in?


Interesting question, anyway.

It is a special case of the Bootstrap paradox, one of the many paradoxes raised by time travel. There are some hyphotesis that avoid this, but mere hyphotesis.

Fascinating stuff.. And yes, Prisoner of Azkaban..

They did the exact same thing in the movie, Somewhere In Time (Christopher Reeves, Jane Seymore).

The movie opens up with a very old woman bringing a young Christopher Reeves a watch and saying the words, "come back to me".
He later travels back in time only to give the watch to a young Jane Seymore, who of course, was the old woman. Who had the watch first? When was it created?

It's simply a fun way for the writer to increase the "magical fate" factor in the plot line of a movie. Nothing more. Everyone knows that paradoxes make time travel impossible. Why over-analyze an enjoyable film by sitting around ripping apart little details in some futile effort to disprove something that everyone already knows is impossible.

You know how impossibly ridiculous Star Wars/Star Trek is??!? Don't care .... I'd rather just thank Hollywood for entertaining the hell outta me for 30+ years.

Hermione was struck by a carved pebble

WTF is Hermione?

Sounds like a lesion, or perhaps an irritation of some sort.

"Ah boys I'm not goin to tha bah tonight, i got hermione all ova my bayack"

It's kind of strange, but as a huge sci-fi and fantasy fan... I find time travel to be too much of a stretch. Magic? Cool... But time travel? Not buying it.
