I want to add, if this frequency, or density, being understood as an actual dimension, and not just a state of mental being then I must disagree exactly with what the 5th dimension is by definition being described or at least a description which is being aloofly espoused here.
Based on my understanding of what the 4th dimension is which is the whole of time contained within this universe from beginning to end, a linear line, and therefor this would mean that the 5th dimension is extended laterally, or planar rather. These lateral individual space-time continuums, multiple universes, that are all slight variation from one to the next paralleling each other until there is a mirror image of each universe within the mutliverse complex on the opposite side of its entirety the 6th dimension.
Such a complex can exist as all individual universe, individual four dimensional manifolds, are curved. Curved as the definition of curved relates to the 6th dimension. This meaning as "curved" relates to the third dimension only as an analogy. The reasoning in using such an analogy is based on the idea that all universes have a beginning and end to them thus they all share the same point of both birth and termination. This could be poles or any point on a sphere, again only being analogized here to relate to our understanding of the third dimension. This means each universe must have an antiverse found on the other side of the multiverse the whole analogized as a sphere, and the sphere represents all of the 6th dimension layer by layer to the very core of which where there at its center point, the center point of everything, a universe where a Big Bang never takes place, only a primeval atom exists. A place contained within the 6th dimension where a universe never forms. The 5th dimension would be the surface of the 6th dimensional sphere so to speak which spirals in on itself to the very center where that primeval atom never forms.
What is the most outer skin of the 6th dimension made up of universes with the longest lives contained within this complex, which btw I can now call 5th dimensional surfaces, I don't know unless there are universes that can exist where there is no end, but then they would have no begging either.
We can roll up sheet or bolts of flat materials in the third dimension, but in the 6th dimension any planar can be rolled up in the shape of a sphere continuously. So am I still using the term "sphere" as an analogy? Not if you can imagine it. If you can, you have arrived in the 5th dimension as you can imagine it, and so you are there... that is here.
I really had fun writing all that above I must say!
