formation
After the whole pattern formation,
the ratio r*/r lies from 3 to 5 in the cells. We maye imagine that the density
and temperature rise, in the matter of the cells, should go with a radiative
energy loss. The surrounding ghost matter could not absorb this emission,
as it does not interact with it, on simple geometrical grounds [3]. The 2d
structure of these matter bubbles is then optimal for this loss, and allows
gravitational instability to occur in this area. So, galaxies could appear,
which would be located in the lacunæ of a distribution of hot ghost
matter, which would penetrate into the intergalactic spaces. Figures 19, 20
and 21 do not come from numerical simulations and are just hand-made schematic
sketches, in order to illustrate the basic idea.

This idea was initially presented
in reference [1] and [10]. The counter gravitational pressure from the surrounding
ghost matter on young galaxies would participate to their confinment. We could
then compare, according to this model, the young galaxies to oil drops suspended
in water. The fact of being immersed in the fluid which confines them does
not prevent their interaction or cannibalism, as suggested on the (schematic)
figure 23.

possible merging

hot ghost matter.
The 3d simulation of such interactions
should require a big computer. At this level, this is only a speculative idea.
We can attempt to study the model of a confined galaxy surrounded by ghost
matter.
