Show me where they are called "dimensional" barriers, then. I feel much of your point hinges on this word being used.
As I said, what the Councilwoman does or does not know is not indicative of anything. She's not some mighty cosmically aware intelligence. In addition, I am not trying to say Kingdom Hearts is exactly like D&D (such a fact would be a nightmare of mine, were it true). Instead, I merely provided an example in which space is not simply "space" but is still spatial in nature, rather than "dimensional".
Is this not already a deeper look? How deep do you need?
Thank you for the reply.
I will have to apologize however, as the “dimensional wall” statement isn’t right. I appear to have misspoke and gotten information mixed up. The walls themselves are never actually referred to as dimensional, my apologies for the incorrect argument.
However, there is a dimensional statement that directly helps my cause regardless. So while I apologize for not being able to provide that specific statement, I do have other evidence that supports my point in its place.
To begin, when Mickey (or Minnie really) banished Pete, he was sent to the Ocean Between. This was to ensure that he could not ever interfere in their world again. The specific wording meant for the Ocean in this instance was “another dimension,” which directly implies that something more than just “far away” is at work here.
Another factor lending to the walls not being purely physical is what the World began as. Initially, the World was a giant, infinite, flat landmass. There was no end to it and the worlds just kinda blended into one another. After the Keyblade War, that infinite world broke, and the worlds got locked away by barriers of light to protect them from the darkness that is present in the Ocean Between.
However, as we see very clearly with the worlds, they are not just planets that seem to have been broken from a bigger piece. They are complete places with their own “space,” their own suns and rules. The worlds have hearts, and just like people, they grow, which is why a world can drastically change as time passes.
When the Worlds broke apart, the rift between them was dubbed the Ocean Between, and the connections that lingered between them became the Lanes Between. Note that Master Eraqus was capable of blocking all of these lanes by himself.
Several times, this “Ocean” has been referred to as something different, and definitely not the same as the normal “space” that exists in other worlds. We know that “space” exists in worlds beyond just the Lilo and Stitch one as well, such as the position of Neverland in reference to London and Deep Jungle showing tools of astronomy. So if we can establish that “space” exists in other worlds, that leads to the question of what makes the “Ocean” different from space.
The Ocean, by Cid, who works on Gummi Ships and has traveled worlds, is called “interspace.” It is distinctly different from normal space. It is “a space between space.” It is an alternate dimension where the rules of a world do not apply.
This also calls into question what the barriers are made of in the first place to reject this alternate dimension entirely. The barriers, as stated by Nomura, are invisible shells that surround a world and are made of light. This is to protect the world from the Darkness, and when the shell is shattered, Gummi blocks are formed from the remains of the shell. However, the Gummi blocks, despite being physical, ARE NOT immediately formed.
When a barrier breaks, the light that made it up becomes flies across the sky of the world, often being dubbed “shooting stars.” After those shooting stars “settle,” they become Gummi blocks. This means that a process has to happen before the light of a barrier becomes a physical object.
If these barriers of light were purely physical, and had no other properties that distort them to keep them separate from the Ocean, why would you not start at the edge of a world and have to find the Heart world within the contained space?
If you were to enter at the edge of the barrier, on a planet that contains the Heart of the world, then look back, you will see an entire physical universe/bare minimum Galaxy behind you. But sora never crosses these. He enters the barrier and appears at the Heart of the world. The same is possibly true for Gummi blocks.
There is no logical explanation for Sora bypassing an entire portion of space to wind up at the Heart of a world, if there wasn’t something non-physical occurring here. Even when he and Donald bumble their way onto Deep Jungle, tumbling and fighting their way past the barrier of the world, they find themselves specifically on the planet that the Heart is located. Despite becoming separated from the Gummi ship crashing long before reaching the planet itself.
When you combine that with the statements of the Ocean being a different dimension, of being “space between space,” then I feel it’s clear to see that the barriers themselves are operating on a “pocket reality” system, where their space and rules and laws of reality are very different from the Ocean or any other worlds.
