Chapter 61: I don't get what the laws of time are supposed to be. At one point, it seems that it's impossible for information to get back more than 6 hours, by any method. At another (and for the test they plan to do on Harry), it's impossible for a single person (or time-turner?) to go back more than 6 hours over the course of a day(/24 hour period?). Or both (with a strange coincidence between the absolute limit and the personal daily limit).
In any case, Harry can pass the test without breaking any laws of Time if he can find someone else with a time-turner.
It certainly does seem to be both. However it's possible that the personal limit per time turner is specific to the construction of the time turners and is not an iron law of time travel. If they were constructed to have personal daily limit equal to the absolute limit ("Who would ever need to go back in time more than 6 hours in a single day?") that would explain it.
Alternatively, the characters are just very confused, but I would expect they have enough experience with time turners that they are familiar with their operating limits (in "ordinary" situations, anyway).
- This thread has run its course. You will find newer threads in the discussion section.
Another discussion thread - the fourth - has reached the (arbitrary?) 500 comments threshold, so it's time for a new thread for Eliezer Yudkowsky's widely-praised Harry Potter fanfic.
Most of the paratext and fan-made resources are listed on Mr. LessWrong's author page. There is also AdeleneDawner's collection of most of the previously-published Author's Notes.
Older threads: one, two, three, four. By tag.
Newer threads are in the Discussion section, starting from Part 6.
Spoiler policy as suggested by Unnamed and approved by Eliezer, me, and at least three other upmodders:
It would also be quite sensible and welcome to continue the practice of declaring at the top of your post which chapters you are about to discuss, especially for newly-published ones, so that people who haven't yet seen them can stop reading in time.
