Chapter 61: ‘There was another pause, and then Madam Bones’s voice said, “I have information which I learned four hours into the future, Albus. Do you still want it?”’
This seems like a useless question. A bit of information was already conveyed representing the fact that Amelia Bones was 4 hours into the future & found some information that would be useful to Dumbledore. Is this not sufficient information transfer in and of itself to prevent Dumbledore traveling backwards?
Sorry if I’m confused, but reasoning about time is hard, and my diagrams are not as helpful as Snape’s and Dumbledore’s.
“Is this not sufficient information transfer in and of itself to prevent Dumbledore traveling backwards?”
Obviously it is not. I’m sure that Harry would find it ludicrous that such a rule exists permitting the transfer of this one bit of information but not the rest of it… but neither Amelia nor Dumbledore think in terms of “bits”.
Btw this “6-hours” window? Though I don’t expect it, it’d be hilarious if in-story this had anything to do with the infamous “TimeCube” ramblings. Something like “Gene Ray was once an Unspeakable that went insane trying to figure out the mysteries underpinning the 6-hours rule.”.
It seems to be anything that would change the actions of the ones who hear it can’t be passed back. I’m thinking it’s a simulation that’s processing 6 hours at once, with the earliest arbitrarily small unit of time being finalized at the same rate new time starts processing. So Harry just needs to upgrade the universe’s hardware and he’ll be good to go further back, but he should be able to get around the maximum daily uses per Time-Turner before then.
In other words:
All Cube Truth denied. 4-corner days, 24 hours divided by 4 corners is 6 hours per corner. The math is simple but no wizards will debate me. Time-Turner can only turn one corner at a time. 4 days are in one rotation. If Time-Turner turned more than 6 hours it would be in a previous day! Turners are connected in ONEness with Time and to disconnect equates death of opposites.
This is the best timecube reference I’ve ever seen. I think its very clear that the wizarding establishment is afraid of confronting your revolutionary claims.
That’s not obvious; what’s obvious is that Amelia thought that it was not. (I guess that Dumbledore also thought that it was not, since he had to think about whether he wanted the information anyway.) Amelia might actually be wrong here; she’s good, but time travel is confusing.
I think the info was sent to Bones rather than her finding it and going back, but your point may still stand. Perhaps “somebody sent something back to Amelia Bones” is vague enough to slip past the filter. There must be some nonzero cutoff, because otherwise the info would affect the whole future (from the point of receiving the info) light come of anyone who got time-traveled info, and the whole earth would be interdicted whenever somebody went back.
If I’m wrong about that, it’s possible that either Bones or Dumbledore wasn’t thinking, or Dumbledore realized that he was already blocked and that’s part of why he decided he wanted the info.
Amelia Bones learns something at time x is an event happening at time x and information of that event could be taken back to time x − 6. If the information that she gets is from time x + 4 then that information could only go back to time x-2.
But she got information from time x + 4: the fact that there was interesting information to get at that time.
Think of all of the logic puzzles where you have (just) enough information to deduce that somebody else had enough information to deduce that somebody else … etc.
I imagine there are many ways in which it can be inconvenient to have information about things that have, from your own perspective, not happened yet. Your own actions could become constrained on pain of paradox when previously they had not been.
But you aren’t allowed to cause a paradox while ignorant any more than while informed. From a determinist viewpoint, your actions are already constrained.
That’s true. When I first considered the situation, it seemed obvious to me that accessing the information could have a controlling effect on your own behavior, but on further reflection it shouldn’t actually matter. However, it would still be able destroy one’s illusions of freedom of choice, which would probably be discomforting, if not actually tactically disadvantageous.
