Okay, I'm just gonna explain this all in detail using actual information from the Extella game and from its Material book because this is getting absurd. This is from the Altera Chapter Prologue by the way.
"The World is not one; rather, like a reflection in a pair of opposing mirrors, it infinitely unfolds. Consequently, there cannot exist only a single future -- or so it's thought. In other words --
Let's explain it like this. The you that exists right now can be described as a you that exists somewhere within this flow of time.
It's probably difficult for you to envision. After all, it's impossible for humans to even perceive "the Boundaries Between Worlds" (õ©ûþòîÒü«Õúü, Sekai no Kabe) -- much less what lies beyond.
So, how about I rephrase? Worlds that run adjacent are essentially as "possibilities." "
See here how the existence of possibilities are acknowledged, and even the denomitation of "infinite" by comparison to two mirrors reflecting off one another. The game itself does indeed say there are infinite possibilities, I even agreed with this. But, here is a little tidbit further forward in this very same info dumb after we are told how worlds too perfect or too hellish can't propagate as choices can't change the status quo anymore.
"But why do such realities become solitary? Shouldn't it be that whatever the future, the possibility of adjacent advancement persists?
Unfortunately, this isn't the case. The energy to account for the proliferation of unnecessary worlds, exists nowhere within this dimension (µ¼íÕàâ, Jige?).
That is to say, the ceaseless proliferation of Adjacent Realities may eventually exceed the capacity of the Dimension as a whole.
Adjacent Realities are a necessary existence, but they cannot be let to freely multiply."
We are straight out told that energy to account for endless multiplication is nonexistant. Now, take into account something interesting.
Multiply, profilerate, grow, and so I ask... how can something infinite multiply? Some infinities are bigger than others from an arithmetic point of view, but this has nothing to do with multiplicating infinity x 2. Just as the finite, if massive, universe we live in expands infinitely despite
not being infinite, adjacent worlds have a finite number that expands infinitely. Notice in the first excerpt the use of "it infinitely unfolds", does that sound like something infinite in span or something infinitely growing?
Now you might ask, what about possibilities? Well they are just that... possibilities. A possibility existing doesn't equate a timeline being immediately created. "
Worlds that run adjacent are essentially as "possibilities.". If we were to draw the timelines in a graph as lines that advance forward, as the game itself does, and a possibility becomes a new timeline 1000 years in the future, is it adjacent to the timeline it sprouted from 1000 years in the past? ... Well no, because
it didn't exist. You can't draw a line because at that point in time, it didn't exist.
"An event that manifests at regular intervals for the purpose of anchoring the Average Expressio (Õ╣│ÕØçÕÇñ, heikin-chi?, lit. "Average Values") of phenomena as absolutes.
This universe permits the birth of unlimited possibilities, numerous adjacent worlds, and divergent developments of history.
However, as the unrestricted propagation of this process would exhaust the lifespan of the universe, at set intervals, those extraneous worlds ''routes'' (õ©ûþòî Òâ½Òâ╝Òâê', sekairu-to) removed of the category of "routes characterized by survivability and stability" are culled (õ╝ɵÄí, basai, lit. "cull" / "prune"), so as to prevent the needless expenditure of energy."
Supporting evidence if it was even needed from the Fate/Extella Material book.
So, even if the moon cell has infinite possibilities recorded, they are just that, possibilities. And now, the biggest issue.
Has literally ANY OF YOU at any point found any sort of evidence that the moon cell simulates all the data it has recopiled? This isn't digimon, this data isn't a thing that exists at all times as something tangible just because it's inside the Moon Cell. The Moon Cell also analyzes the planet every nanosecond, do we have billions of trillions of planet earth's inside the moon cell as well because of this stored data? Are the Servants manifested at all times somewhere since their data exists in the moon cell?
"It is the brain that stores the data about the past and future.
It observes the determination of every possible destiny every second, computes further results, and stores everything inside itself as light. There are untold tens of millions of lights years of light trapped within the core, and the entire photonic crystal structure is also powered by it.
A certain person named Moon Cell's core, "The Destiny Perceiving Dendrogram." "
Observes, computes, and then stores everything inside itself as light. As a quantum supercomputer made of photonic crystals that use light itself to make calculations and as a storing device for data, does this sound like infinite Low 2-C timelines stored inside of it, or like records and data it has calculated? Because, you know, it's an observation device. Even terminating "infinite possibilities" means nothing, if those possibilities are born from very, very finite timelines. Shut those off and where are possibilities gonna come? From nothing? This means the Moon Cell gets a 2-B at best, and that's only because of Last Encore. There's also Upgrade's direct statement about the finite nature of the moon cell, but that's a side thing.
