Oh, okay. If I remember correctly, this was suggested by Dumbledore in canon (with some handwaving about Voldemort not noticing it, because his soul is too hurt), that's probably why this didn't occur to me.
I read the scene as the stratosphere idea being a precursor to the space idea, not an idea on it's own. Although after re-reading, I'm not so sure anymore…
(Fire, Earth, Water, Air, Void/Ether.) Also, canonMort settled on six Horcruxes because he thought splitting his soul into seven pieces would have some beneficial effect (never specified, perhaps because his first 'crux was destroyed by the time he made the sixth). If the stratosphere doesn't qualify, that leaves a Horcrux unaccounted for.
The next discussion thread is here.
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 85. The previous thread has long passed 500 comments. Comment in the 15th thread until you read chapter 85.
There is now 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.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
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:
