@Telomera Can you create a final response based on your current points so User is able to create his?
Sure I guess.
I don't think it's particularly necessary for me to expound any further on why Sonic Prime and Sonic '06 are bad examples since it seems to be mostly accepted that they're not sufficient proof, so I'll argue against using Crisis City as proof and also bring up counterevidence against the existence of a hypertimeline in Sonic as a whole. Refer to the OP if you want to read more about that.
I'd like to emphasize the fact that for there to be proof of a hypertimeline, there has to be proof of
nothing less than a higher dimension of time where there is at the very least an uncountably infinite amount of snapshots with entire timeline(s) in each snapshot. The opposition is trying to prove the existence of this higher dimension of time by claiming that the Time Eater supposedly used time travel to restore Crisis City. Keep in mind that
with this particular method of argumentation, it is absolutely necessary that they prove that "time travel" is used to directly travel to another version or "snapshot" of an entire timeline (it is so necessary in fact that it is described as "the keyword" in this case). Note that it's not
just time travel causing changes in timelines which may then be accessed afterwards (which
doesn't require a hypertimeline), but time travel has to be able to
directly access these different versions or "snapshots" of entire timeline(s). Without this, they are left with no argument that the development of the timelines between these versions/snapshots is a "time-like" development along a higher flow of time. Without this, their entire argument falls apart. The issue with the opposition's argument is that they have no proof that anyone ever used "time travel" to access a past version of a timeline.
First of all, it's never established that any sort of "time travel" caused the restoration of Crisis City. The opposition has tried their best to prove that the Time Eater directly and intentionally caused the restoration of Crisis City, and while I'm not conceding anything, I want to point out that they have never provided any proof that "time travel" was used by Eggman/Time Eater to directly access pre-erasure Crisis City. Without this, they have no method of claiming that the development of timelines is time-like. They do seem to argue that it's because Time Eater makes heavy use of time manipulation, but it's stupid to pick and choose whatever thing you want that Time Eater did and claim that it was done through time travel just because Time Eater uses a lot of time manipulation powers. You cannot say that a certain thing done by Time Eater was done through time travel unless it is specifically stated; otherwise, you would be committing the
association fallacy
Secondly, in Shadow Generations, Gerald Robotnik
responds to Shadow asking him about Mephiles by explaining that as a result of the timestream being tampered with, echoes from the past are being stirred up, which explains why Mephiles (someone who Shadow has no knowledge of since Mephiles's timeline was erased at the end of Sonic '06) is there. (there is a past because
the timestream was healing itself along with Sonic and Shadow helping restore it btw) This means that instead of being a past snapshot that Time Eater traveled to via time travel, Mephiles and Crisis City are just echoes of an erased timeline that were stirred up by the Time Eater's meddling with the timestream. It's not an entirely different snapshot of a timeline, but just "resemblances/leftovers" of an erased timeline as Qawsedf put it. This was an educated guess on Gerald's part, but it makes a lot more sense than Eggman randomly stopping his rampage across time and reaching back in hypertime to restore a timeline he didn't even remember (Gerald
actually said his theory was correct but I'm not 100% sure if this also refers to him talking about the echoes)
Now, I will respond to some counterarguments. Theuser789 claimed that this contradicts the fact that Time Eater made a portal to the erased Crisis City before destroying spacetime. But not only is this not confirmed to be an instance of "time travel" (which is absolutely necessary for a hypertimeline argument since
there has to not just be an arrangement of snapshots, but a time-like arrangement of uncountably infinite snapshots), it fails to account for the fact that
the Time Eater had already been destroying spacetime even before it
opened the portal to Crisis City in modern Sonic's timeline. That means that the
"damage done to the time stream" that had been "stirring up" the echoes of Crisis City and Mephiles had already taken place by the time the portal was opened up. There was no need for Time Eater to reach back into some sort of hypertimeline to get those echoes because those echoes were already there (
which would also explain the presence of Iblis since all versions of Iblis were parts of the '06 timeline). This order of events is made quite clear in the cutscene, and it makes no sense to deny it.
Theuser789 also argues that Crisis City coming up in Eggman's flashback proves that Eggman must have gone back in hypertime to pull Crisis City out of nonexistence, but this a huge stretch. All that this appearance means is that the presence of Crisis City was one of the consequences of Eggman's plan, specifically due to being "stirred up" as a side effect of his tampering with the time stream. There's nothing more to it than that, and anything more is headcanon and a non sequitur.
Now considering all this, the opposition has no way to justify their claims of the existence of a hypertimeline, which should be enough to remove this scaling. But that's not all. There's actually counterevidence that actually goes against the idea of there being a hypertimeline in Sonic at all.
The fact that only echoes are left of Mephiles's timeline being erased contradicts the claim of a hypertimeline, because if there was a hypertimeline, the erasure of Mephiles's timeline would be nothing more than a movement from one snapshot to another. Mephiles's timeline would still exist in its entirety as a past snapshot. The fact that only echoes are left of Mephiles's timeline contradicts this. This is further supported by the fact that
Gerald confirms that if Shadow were to change his past, it would also rewrite his future and that all the things he did in the timeline originally
would cease to be, which is absolutely not how a hypertimeline works. In a hypertimeline, past versions of a timeline continue to exist. On the contrary, Gerald confirms that they cease to exist. This actually does happen to be relevant to the Crisis City issue too though because, since old versions of timelines cease to exist when a timeline undergoes change, Eggman wouldn't be able to reach into the "hyperpast" and pull Crisis City out since it would've disappeared already. That's yet another reason why Gerald's explanation with the "echoes" makes much more sense than any of this hypertimeline stuff.
Also, it's outright confirmed both
here and
here that there is just a singular dimension of time, that time is only one dimension.
In all, not only is there no proof of a hypertimeline, there's actually counterevidence that
disproves the existence of a hypertimeline in the game Sonic verse.
