I don't know at this point how many times I'll repeat this, but here we go:
Vivziepop explains that these are cosmic representations, hence why they look like planets and seem to be the sizes of them, now this doesn't contradict whether or not they can be reached or whether or not they are universes.
The only reason I'm using the idea that they are within a larger universe rather than 2 universe is because
the wiki dictates that I'm supposed to do that, which proves that there's actual instances of this in fiction, and rather than just denying them, made a rule to bypass it without accepting them as separate spacetimes but still possibility of them being universe-sized.
Literally without the context of the scene this wouldn't have been accepted as actual universes.
I will no longer respond to another message regarding this argument unless a CRT is made on it.
