About insignificant dimension...

[Im_Fire444]

So, I know that the structure that seperate 2 different space-time would scale be insignificant dimension unless it has statement of being infinite.
But what about a 5d or any higher dimension stucture which doesn't seperate 2 different space-time but it is like 4d space-time but higher Dimension and has no statement of being infinite in size... Would insignificant dimension be applied there?

what you mean by 'doesn't seperate 2 different space-time'?

I mean that I already understand a structure that separates different space-times is 5D. So I’m not talking about that. I’m asking, if there’s a structure that is higher dimension which doesn't act as seperation, existing like a 4d spacetime but higher dimension like 5D or 6D, and it’s finite in size, would the concept of ‘insignificant dimensions’ still apply?

so like you're saying
4 spatial + time?

If so
it would no longer be Insignificant if the Time exist higher than all spatial dimension and goes infinitely into the future

if its 3 spatial + time + space higher than time

Then one needs to know if the space is infinite in size else insignificant size

But if its only 4D + time on a specific limited area (entire universe is 3D + time but one area has higher space but only the size of a room) that is not universal in size it will be insignificant

There is no correlation between insignificant dimensions and the opposite acting of separation between 4D structures. An insignificant dimension is just a concept when the uncountable infinite is not met thus lacking an additional axis.
And you haven't given me an example of what constitutes non-separation? encompassing, contiguous, superimposed?

Spoiler: uncountable infinite

At this very moment, the multitude, as 'Cuboid' beings, are curling towards a more microscopic realm unreachable by four-dimensional physics, transforming into 'Stacked' life forms!

In this instant, it was as if they saw the entire four-dimensional spacetime: it was a quadruple helix structure, an image akin to a vortex, with afterimages stretching continuously, as if countless three-dimensional light cone diagrams were superimposed.

Every shape in space is merely a facet produced when a higher dimension intersects with this spacetime. Like a face on a cube, or a circular arc on a sphere.

Now, they could deeply appreciate and intuitively perceive that the four-dimensional forms they had understood before were also merely part of a five-dimensional form.

Energy from the fifth dimension was stretching them, coiling them; infinite details flooded in, infinite facets of the myriad phenomena converged into one.

Virtual particles from the fifth dimension were filling the angles they lacked, just like folding a sheet of paper into a thick book.

A high-dimensional object could encompass lower dimensions.

Spoiler: without being infinite in 6d scale

"Palace of Life?" Ku Ying murmured.

Its completed form, in the sixth dimension, spans approximately one hundred thousand light-years in diameter and resembles a disc. Of course, this is merely an extremely partial description; as a six-dimensional entity, describing it with any shape is fundamentally incorrect.

Any single facet of its enormous body consists of countless five-dimensional shapes, and the curved boundary surfaces of these shapes are, in turn, countless four-dimensional geometries.

Within even a single crevice upon its intricate patterns, a vast and complex three-dimensional star ocean could be embedded.

By design, it is intended to contain the entire Soul Sea.

Not only that, but its surface can also embed all worlds of the first, second, third, fourth, and fifth dimensions. Even new worlds that emerge in the future will appear within the crevices of the countless integrated patterns upon it.

For Huang Ji, repairing the Source of Life this time involves more than just recovering all the fragments and letting the Wanhuajing¹ merge back into its prime state.

In the very beginning, wasn't the Soul Sea also a complete entity? Yet countless trans-dimensional beings still reduced it to its current state.

Thus, Huang Ji sought to create a vessel to contain all worlds, including all things and all sentient beings within them.

If the three-dimensional world is a page, the fourth dimension is a book, the fifth is a bookshelf, and the sixth is the entire library.

What Huang Ji aims to do is precisely to build a Palace² to protect this library, preventing it from being smashed, looted, or burned ever again.

With the passage of time, the library's collection here will only grow, the bookshelves will only expand, and the content will also become ever richer and more advanced.
