Well. Below scan says negative zone shares same three dimension as man's universe/multiverse.
That comic is absolutely ancient. New information (The scan I've shown is from 2014) naturally overrides old, especially in a medium like comicbooks. Furthermore, this doesn't prove an issue if the Negative Zone is treated as separate from the nexus of realities that is accessible from its core, by extension meaning that Doctor Doom's statement in FF #14 was referring to the latter.
Either option you take, the statements regarding the Crossroads are left largely untouched. Even if I was to humor what you say, why wouldn't they? Reed reaches the place after he stumbles through a 4-dimensional realm and in a later venture to it mentions that it contains 6-D spaces, so implying it is 3-D is out of the question as is.
Contextless? It had some context that's why it got rejected in past unless DC is 1-B so far.
but there is no further context about the Marvel scan. why even the character mention it take as a reliable source? It's not a explicit mention of higher dimensions by any means.
First paragraph is missing the point by a mile. My point is that using a scan from another verse entirely to say that Marvel is commiting a gross misuse of fairly basic terms is absurd, and moreso when you don't even explain how this scan exemplifies such a thing.
Second paragraph falls under something I've already addressed: If the narrative does not treat the statement as having ambiguous veracity, then there is no reason to disregard. Now: Does the narrative treat it as having ambiguous veracity?
I think the fact that his mention of controlling dimensionality is prefaced by a considerable amount of text talking about alternate universes should dictate that this scan is definitely about universes, not spatial dimensions.
Not exactly. Some context from this comic and the one adjacent to it should help here: Basically, the scan above is Doom discussing the prospect of obtaining master control over all space and time, and, more specifically, the two main ingredients he needs to absorb into himself as to accomplish this: Control of the Negative Zone, and, as he mentions, Kang's mastery over time, so, "controlling dimensionality itself" in context is referring to full dominion over space (Obviously related to geometrical dimensions) that he'd obtain by controlling the Negative Zone.
Here's an album of relevant scans that I compiled for clarity's sake.
This is, of course, not mutually exclusive with the mention of alternate universes. Dimensionality is a property of the universe, and that the Crossroads of Infinity are already demonstrated to have close ties to dimensionality (As shown by the Fantastic Four Unlimited scans) should seal the deal for that here.
I don't necessarily disagree with this argument, but I can see both sides. You're right in that the comic explicitly portrays Reed as shifting through various levels of spatial dimensionality as he goes through different realms, indicating that he is taking on the dimesnionality of the various realms he's in.
I am not sure it is so concrete, however, that him reaching the crossroads and saying "limitless dimensions" should also refer to dimensionality. I think the evidence is not bad, but strongly obfuscated by the fact that he is literally in one of the only places in Marvel where describing himself as being "in a world of limitless dimensions" could refer to either spatial dimensions or universes.
Further by the fact that the next two descriptions he gives the realm refer to it's access to other realms, not spatial dimensionality. "I'm drifting into a world of limitless dimensions! It's the Crossroads of Infinity -- the junction to everywhere!"
I think it could go either way, but it strikes me as an odd coincidence that he would be describing both at the same time.
I don't find that an odd coincidence at all. As said prior, dimensionality is obviously a property of universes, and Reed in this case is in the realm where all such universes meet, so it referring to both is all but natural, and supported both by Doom directly likening dominion of the Negative Zone to dominion over space (Which, again, obviously ties into dimensions in the geometrical sense and informs us that "controlling dimensionality" was, in fact, referring to controlling dimensionality) and by Reed using "juncture of many dimensions" in a geometrical context the next time he goes into the Crossroads (For the matter,
here's direct confirmation that the juncture in the Annihilation Area was the Crossroads of Infinity, from 2013). The fact that he mentions "limitless dimensions"
right after he talks about being in a 4-dimensional realm also, in my opinion, provides some contextual backing to my stance, especially in conjunction with the other scans.
It was with regard to the Cantor "transfinite sets" scan. Essentially it was said that if taken at face value, setting aside the poor explanation of greater infinities, saying that Marvel has Aleph Infinity universes or levels of power would render it 1-A+. This was mentioned in defense of it's dismissal for the aforementioned bad mathematics. I am defending the scan, not because I think it should be used for 1-A+, but because I do not think the poor explanation of how greater infinities work should by itself be used as a reason to dismiss the scan entirely. Most things that we evaluate at that level do not reference the advanced math involved at all, and to me it seems backwards to 'punish' the author for at least trying to communicate the concept of greater infinities. We are all aware that adding two countable infinities doesn't create an uncountable one, but how many old-school comic authors know that? I just don't agree with rewarding silence. The intention was clear, and they explicitly reference an infinite series of greater infinities. That being the case, we should use a different reason to dismiss it than "the author didn't reference bijection"
I can get behind that sentiment, yeah. In that case, the statements as Kubik applies it to himself, Kosmos and the Celestials would be disregarded, but not the concept of aleph numbers in Marvel as a whole, especially given that later comics reference the different levels of infinity in set theory without delving into enough detail as to accidentally explain them wrong.
