How does Time travel work in Harry Potter universe?


In Harry Potter and the Prisoner of Azkaban the logic behind time turner travel seems to obey a Stable Time Loop or Causal Loop, where you fulfill what has already happened.


However in Harry Potter and the Cursed Child,




after the reintroduction of time travel, time turners now seem to work in a Back to the Future/Time Cop kind of way, creating alternative timelines, even though in the end they fix them.



My question is: How does time travel really work in the Harry Potter universe? Are these two canon works really compatible? Should we dismiss incompatibilities as plot holes or is there really a good unifying explanation?



Answer



TL;DR: Magic


I think the easiest way to reconcile this is by thinking about what was changed, and how far back they traveled.



said Dumbledore quietly. ‘Hasn’t your experience with the Time-Turner taught you anything, Harry? The conse- quences of our actions are always so complicated, so diverse, that predicting the future is a very difficult business indeed ... Professor Trelawney, bless her, is living proof of that.



In Prisoner of Azkaban, Harry and Hermione only traveled a few hours back in time, and they fixed or altered their own events that we the reader didn't actually know the outcome to. The events did not have time to have ripples that drastically altered the world around then, and Rowling wanted to tie in a time loop style event.



Scorpius and Albus, on the other hand, went back in time 20 years to firmly established events, which massively altered the course of history and, in one instance, resulting in Albus not even being born.


We know that, even in Prisoner of Azkaban, that Hermione states that these "Back to the Future" style time traveling is possible.



‘Exactly! You wouldn’t understand, you might even attack your- self! Don’t you see? Professor McGonagall told me what awful things have happened when wizards have meddled with time ... loads of them ended up killing their past or future selves by mistake!’



Its clear that even originally time travel could act in this way, however, for the sake of her plot in Prisoner of Azkaban Rowling tied it up neatly in Time loop Scenario.

futurama - How much time is lost in 'Time Keeps on Slippin''

In time Keeps on Slippin' , Farnsworth creates a basketball team which he matures by abusing Chronitons. This leads to time skipping forward by random, but ever increasing amounts. How much time was skipped in this way? Answer Unfortunately, I don't think a good estimate can be made for this, for two reasons: Many of the time skips move forward by an indeterminate amount of time. At one point, the Professor mentions localized regions of space skipping forward much more than others. We then see two young boys on the street below complaining about having to pay social security, only to suddenly become senior citizens and start complaining about wanting their money. Thus, each individual could have experienced a different amount of time skippage.

harry potter - How could Expelliarmus beat Avada Kedavra?

I want to be very careful about how I ask this question – I am not asking How did Voldemort die? [CLOSED] Below the text is the relevant passages from Harry Potter and the Deathly Hallows if anyone wants to review them (I'm sorry for the amount of text). How did Expelliarmus beat Avada Kedavra and kill Voldemort? I feel the reason Harry's Expelliarmus overpowered Voldemort's Avada Kedavra curse has to do with who was master of the Elder Wand and how the Elder Wand works. I've always had trouble understanding fully how the Elder Wand works, though. How much did the fact that Voldemort never truly won or mastered the Elder Wand factor into how Expelliarmus reacted to Avada Kedavra and caused Avada Kedavra to rebound and kill Voldemort? An answer based in book canon would be especially welcome, but any canon source really is fine. Harry heard the high voice shriek as he, too, yelled his best hope to the heavens, pointing Draco’s wand: ‘ Avada Kedavra !’ ‘ Expelliarmus !...

game of thrones - Is Syrio Forel dead?

In the episode 'The Pointy End' (Season 1 Episode 8) when Arya runs from the Lannister guards you hear the sound of a sword being dropped (around 4:56): [embedded content] After that neither Syrio or Ser Meryn Trant is never mentioned or seen in the show again, except when Arya mentions to the Hound that Ser Meryn Trant killed Syrio. Is there any mention in the books that Syrio actually dies?

tolkiens legendarium - Difference between elves and dwarves blacksmithing in the Lord of the Rings

Both the elves and the dwarves were famous for their metal work in the Lord of the Rings trilogy, but what is the difference between what they made, and which one had the better skill of making amours and swords? Answer James Christopher's answer sums up the second part of your question well, but as to the difference in what they made, a little more detail is needed. Once the Elves learned to forge with steel, the shape of the sword changed, now being able to take on the form of a great broadsword or a light and agile curved sword. Additionally, they took great pride in decorating their swords. As we see in the Lord of the Rings , some swords like Sting had magical properties such as glowing blue when orcs are near. As far as the use of Mithril, lotr.wikia has two contradictory passages: Thus, Elven blades became renowned as great weapons, capable of performing deeds beyond the skill of their handlers and were even more glorious when the use of Mithril was allowed to the Elves. ...
