There are at most aleph-zero disjunct 3D spheres in 3D space. And there are at least aleph-one disjunct 2D circles in every finite volume part of the 3D space?
The number of points in N dimensional space is always aleph-one. And you can also divide this space into aleph-one disjunct N-1 dimensional spheres.
Is there a way to divide 3D space into aleph-one cubes with no common volume? They may touch each other, but may not share some common volume.
If you can find one such space division, you brought down the ZF Set Theory.
