Cosmic Filaments vs Foam and Bubbles

There has been some recent discussion in this group
about the distribution of matter in the universe.
Some say that matter is distributed along filaments,
with large voids in between. Others liken the
structure to that of *foam*, in which the filaments
are the regions where two or more bubbles (or voids)
intersect and part.

There was a article, asserting that dark matter formed
the lattice on which the rest of the universe was hung.
This dark matter formed clumps first, then attracted the
normal matter.

I was wondering if there wasn't a different possible
explaination. Rather than dark matter attracting regular
visible matter, perhaps it caused some outward pressure,
such as an expanding bubble, and it was the regions in
which these expanding bubbles intersected that regular
matter was clumped together.

One might imagine that a container of expanding bubbles
would itself tend to expand, thus accounting for the
inflationary period of the early universe.

Cheers,
Larry G.
