If Harry gains access to arbitrarily powerful time travel (That's how I've interpreted your scenario. I apologize if I'm wrong.), doesn't that make the whole plot redundant? Can't Harry just go back to the beginning and tell himself everything?

Well, what if even uber-time travel still has the paradox limitation. Harry figures out his becomus-goddus spell, and can go back in time arbitrarily far.

But if he mucks about with his own past in any way he doesn't remember he may unhappen his omnipotent ass. Moreover, this is true of almost all of history. Any mucking about that might prevent his timeline from making him invincible would be verboten.

So, what could he do? Not go back and tell himself everything, it would be a big gamble that his past self could consciously fake its way through the eve... (read more)

0ReevesAnd5yI would guess that the time travel would keep the restriction that he can't change the past. So he could recover her body and resurrect her in the future, but couldn't change the past events.

Harry Potter and the Methods of Rationality discussion thread, January 2015, chapter 103

New chapter, and the end is now in sight!

This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 103.

There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)

Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.
