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.

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.

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.

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.
