Wait, she who? Any-who going over the tings, I'd like to throw in my two cents.
I think the infinite light and darkness thing is pretty mundane to argue about. It's only another way of saying the universe is infinite, so no reason to waste time on minor details.
Next is the shot we get of universe 6 and 7 and how we see boarders on them. Yes, they look like they are contained in a "bubble" but you have to consider two things. A, we can't comprehend what infinity looks like especially artistically.
They are drawn like how you'd see a typical collection of universes. And B, having spatio-temporal barriers wouldn’t contradict anything. Infinite 3D is always going to be lower than finite 4D so looking at it from that perspective, which I'm sure is the general consensus since we can't visualize space-time, should be no problem.
Then we have the center and edge arguments. I don't want to dwell on this, but imagine this. A big bang has an explosion radius of infinity. It has a starting point in the center and everything outwardly expands to an infinite distance unpon detonation. Looking at it this way is simple.
Infinity can have an end in the sense that you can traverse it in a specific amount of time. It's how we treat infinite speed, characters reaching the end of an infinite distance in a finite time.
And to briefly go over the super dragon ball radar thing, you can argue that it's range makes the universe look finite at a certain perspective because of higher dimensional range stuff, since 4D can make infinite 3D look like nothing. I can't go into too much detail cause I gotta go in a sec
but you get the idea.
