Abstract

We provide a new tool to interpret the large scale structure of the Universe. As suggested in Paper II, energy density filaments could have been produced by subjacent magnetic flux tubes when the Universe was dominated by radiation. In more recent time epochs, small scale filaments have evolved in a complicated way, but large scale filaments have probably survived and should be identified with present observed matter filaments of clusters. A primordial magnetic field lattice made up of magnetic flux tubes would then have originated a matter lattice made up of cluster filaments. Taking into account some restrictions in the magnetic field configuration we speculate what type of matter network this would have generated. The simplest lattice is made up of octahedra connected at their vertexes, reminding us of a structure of superimposed egg cartons. The vertexes would correspond to large superclusters, which would therefore have eight filaments emerging from them. Some observational evidence is found in the Local Supercluster, which is spider-like, with eight legs.

Key words: Magnetohydrodynamics (MHD) - relativity - cosmology: large-scale structure of Universe - magnetic fields
