The egg-carton Universe

The distribution of superclusters in the Local Supercluster neighbourhood presents such a remarkable periodicity that some kind of network must fit the observed large scale structure. A three dimension chessboard has been suggested$^{1}$. The existence of this network is really a challenge for currently-suggested theoretical models. For instance, CDM models of the formation of the large scale structure predict a random distribution of superclusters$^{2}$. If the filaments of matter that are now observed building up the network are fossil relics of over-dense regions of magnetic field energy before Recombination, then it has been shown$^{3}$ that the simplest network compatible with magnetic field constraints is made up of octahedra contacting at their vertexes. This suggests a set of superimposed egg-carton structures. Our aim in this paper is to show that the real large-scale structure is actually fitted by the theoretical octahedron structure.
