LegionZero wrote: Dimension can refer to perception, which would be more in line with the concept of 4 and 5 dimensionality. A more proper name would simply have been a parallel reality or a pocket universe, although that tends to create the wrong impression (IE a vast expanse of space, whereas in Obito's case it seems to be more of a rather big room)

LegionZero wrote: Each of these dimensions have at least a star and a planet far enough away to sustain earthlings and far enough away from the edge of the universe that it can't be seen I seriously question the idea that they're all in different star systems. I also serious reservations about whether she was going to actually destroy the time-space or the planet, and how she made it.

The big problem i have is that it's absolutely not clear how much power it actually costs to make such a dimension. Obito has his own kamui basement, yet when he awoke Kamui it wasn't like he nearly exhausted himself creating the dimension itself. It's not even clear how big it is, since it seems he can enter and exit the dimension from anywhere regardless of his actual position in the Shinobi world or his actual position in the Kamui world. Yet the times we see the kamui dimension, we never see it's edges.

The second big problem is that we have no idea about the rules regarding the creation of pocket dimensions. According to certain interpretations of Quantum Mechanics, a vacuum can spontaneously form a universe without external input. IE, If obito or kaguya splits off a tiny piece of reality from our own world they can theoretically spawn an entirely new universe.

The third problem i have is one regarding time. Judging by Obito's basement space, the creation of space-time itself is not energetically that hard. So i can conditionally buy that Kaguya can create large empty spaces. But she had possibly thousands of years to make her own worlds (Which also creates questions such as "why"?). If she's on the higher end of Continent level then periodically dumping some of her excess power into some Earth Release jutsu could easily form a planet in, say, a century.

The fourth and final big problem i have is mostly one of terminology and context. Kaguya calls the Shinobi World her "seed plot", and i see a strong connection to her "Dimensions". I can easily see that Kaguya simply has Dominion (in the Tolkien sense) over the solar system and considers that her "time space". A big enough star can fit quite a few planets in it's Goldilocks zone, assuming she didn't use any external methods to terraform them (IE if mars spontaneously formed an atmosphere like earth, it would take millions of years for it to revert to modern-day levels).

The lava planet could easily be the closest to the star, the ice planet furthest. I don't see why it can't fit within one solar system, with Kaguya making either all planets inhabitable or Kishimoto simply using Artistic License (IE like ninja standing in space on the surface of the moon)

This is why i have such a huge problem with kaguya being solar system level: I see so many variables and so many unknowns.

LegionZero wrote: Good point on the hollowness of the moon. I checked some clips from the Last and looking at the thickness of the holes they are not very thick at all. I was actually shocked how thin it was. But yea, considering what we see Naruto, Sasuke, the Juubi and madara do, Toneri's power is somewhat in line with theirs. It seems to me that Toneri used up most of the Tenseigan's power in one fight, whereas the other characters weren't still at their reserve limits, so i'd say that their levels are roughly comparable.

So i understand the dispute about whether he "destroyed the moon", i think it's not really the right question to ask.

Still, i'd like to make clear that a planet is really really big. Despite not seeming so, the difference between "continental" and "planetary" is still huge.
