Astral Plane Question

[kgy121]

When a bag of holding is placed within a portable hole, a rift to the Astral Plane is torn in that place. Both the bag and the cloth are sucked into the void and forever lost. If a portable hole is placed within a bag of holding, it opens a gate to the Astral Plane. The hole, the bag, and any creatures within a 10-foot radius are drawn there, the portable hole and bag of holding being destroyed in the process.

So what happens if you do one of those things after plane-shifting to the astral plane?

Not planning on doing it, just curious.

Recursion! :D

Purely by the rules, with no regard for actually making much sense? Probably a rift to a different part of the Astral Plane.

You shouldn't be able to take such items to the astral plane in the first way. Or if you do, the inside of the item should be as large as it's outside.

Assuming the astral plane is a 4th (or higher) dimensional space, then physical travel to it would mean that everything inside it also exist in four (or more) dimensions, but the mortal mind makes it appear as three dimensional. That means you have a bag of holding that has four dimension on the inside, four dimensions on the outside, and all the items in it are also four-dimensional. The cube/square-law (or in this case the ³/⁴-law) would probably allow to store more things in any container than in the normal three dimension, but since travelers are not instantaneously imploding once they arrive in the astral plane, there probably would be something at work to prevent that.

So I say, when you go to the astral plane with a bag of holding, it loses its magical properties, everything inside it expands to normals size, and probably rips the bag to ribbons, spilling the whole content. However, there are no effects to the dimensional fabrics of the planes.
