I was right. I do regret raising this question.
It seems the planet doesn't have a fixed destiny. It has a range of possibilities, and among those possibilities, it has preferences, which it wishes to enforce.
I say "potato," you say "potato"... Same difference
But it cannot have "future memories", because you can't have a memory of something that hasn't happened yet. I am perfectly fine with accepting that the Lifestream exists in an eternal "now" which contains past, present and future; in such a scenario, temporal beings could experience their glimpses of the future as "future memories". I have more trouble accepting the logic that the Lifestream contains both timelines which it desires AND timelines it does not desire. I reject the logic of a future that both simultenously exists and hasn't yet come into existence.
Sure it can. Just like Aerith can have
future memories of events
yet to happen that might
not happen. It's like a script. A vision. The planet's aware of what is supposed to happen, and it has the data (souls and memories) to ensure it happens, but the progression of physical reality is still in flux.
The Lifestream doesn't "contain" a timeline, it more like triggers the creation of one. I don't think the timeline itself exists in the Lifestream, but I think that inconsistency and schism within it would prompt an existential pull that would cause a split timeline to form.
I mean, you can reject that logic, but it's pretty much staring you in the face at this point. Zack's
alive, but also seemingly
dead from another temporal perspective. How does
that work?
If the timeline "splits", how exactly does this happen? Where is this parallel world? Is it sharing the original Lifestream or does it now have one of its own, i.e. a destiny of its own, which the alternate Planet also seeks to protect? And presumably somewhere the original world is still following the original destiny? Is this like mitosis, but one of the daughter cells has a mutation? Or is it more like cutting up a cake into ever smaller pieces?
I mean, I can't tell you exactly
how. But usually, when something changes history, that's what causes the timeline to split. The timeline splits to accommodate the change without winking reality out of existence.
That's the question I'm really curious about, regarding "sharing" the Lifestream. There's clearly connection between these two worlds/timelines. Aerith feels things. The symbolic crossing of paths of Cloud and Zack, with Cloud and Aerith. There's like, something there that ties them together. I dunno if they share the Lifestream exactly, but they're connected in some form or fashion. I used the comparison of a parasitic twin because I do think they may share a spiritual connection that might cause one to have to succumb to the other.
My problem with all of this, is that time/destiny only makes sense, when it's a universal concept, not a planetary one. Because time works the same way everywhere. So if you make it contained to a single planet(with it's entire history already written), what happens when something outside of it's time bubble disrupts the flow(like something crashing on the planet)? Then the already written history/timeline of the planet would change(since the crashing wasn't written in it's history)? And what if another rock crashes on the planet? And another one? And another?
Well, maybe there's an even greater network of souls that exists on a planetary, universal level that this works on as well. Sorta like how Omega and a planetary death fits within the spiritual cycle of the cosmos. That's a very real and logical possibility right there. I'm just focusing solely on the Planet since this is all about the Planet, but it can easily work on a wider scale just like all spirit energy does.
Deepground is the friggin' BREAD CRUMBS of retroactive continuity compared to how invasive the Whispers are if we're supposed to imagine them existing in the original game's world. At least Deepground is hiding underground, but the Whispers are swirling about in countless locations, guiding events endlessly for millions and millions of years.
...and that's why I'm passionate about the Whispers being the planet's post-AC/post-DoC immunity response to a nexus event that created all the time shenanigans in the first place.
Well, up until this point,
nothing would have ever been capable of careening the Planet's life off course. The entirety of FFVII and the planet's near death was part of the proper course of "destiny" the Planet saw for itself, so that right there tells you that yes. Something significant happened after all that to somehow necessitate "Feelers" to "feel" out what is wrong and try to put it "right." No, I don't think the Arbiters of Fate have had to literally shape history like the Occuria did for Ivalice. I personally think Sephiroth did something significant in the future to cause this. Maybe in pursuit of finding his "Promised Land" and making the Planet finally accept him as its "god" or something.
