5) Some remarks. Didactic model.
With a higher number of mass points, we could have highlighted the formation of clusters and the spongy structure on a 2D sphere. The following images do not correspond to 2D simulations, but are simply hand-drawn. Everyone has seen a football. It is made up of pentagons and hexagons joined together. A suitable choice of parameters could provide such a distribution of clusters and ordinary matter, corresponding to figure 23.
Fig. 23 : The football. ** ** We have twelve pentagons and we suppose they represent twelve ghost matter clusters, organizing the whole system.

Next, the expected distribution.

In a previous paper [14], we presented a didactic model of conjugated gravitational instabilities, using a tank filled with water, a linen, two sets of heavy balls placed on top, and ping-pong balls located below the linen. The heavy balls press on the linen, causing the ping-pong balls to tend to lift it. Imagine that the ping-pong balls form a set of bumps, as shown in figure 25, simulating the clusters of ghost matter. Ordinary matter, small light balls, would be positioned between them.
