It kind of irks me that they basically assume a cubic lattice. Nature does not form cubic lattices, when nature forms a lattice (for example, in a foam) it tends to form roughly dodecahedral cells (with coordination number 12). Given this property, a space-time lattice would be very nearly isotropic.

Would a dodecahedral lattice explain why the universe stays symmetrical while expanding?

It kind of irks me that they basically assume 3+1- space-time.

While you're largely right, salt disagrees.
