Utter conjecture;- We see superclusters forming mass filaments along the 'edges' of poincare-like manifolds. The seemingly dodecahedral structures present in our universe may have been created on the edges of simple geometric 'kissing' surfaces (sphere packing) where the edges would represent zones of energy minima. I suggest it was here that matter 'condensed' from BH wave-state expansion. If voids in our universe start from a central point (in relation to the 'edge' superclustering as per dodecahedral substructure) all void centres within our universe may in fact be ultra-massive primordial black holes;- mini universes in their own right. Proof of these would involve looking across space from our part of the universe through an extrapolated point representing our void centre ..... outwards, beyond to the far side filament superclusters. My prediction;- a huge gravitational lensing effect might be seen.
