Yes, but after years of searches I think that is useless to go on
denying that we just have no idea how the universe works. No physical
counterpart of the supposed "dark matter" has been found in any lab.

There is no dark matter particle and hence exotic dark matter doesn't
exist. Normal matter could have unknown behaviour however, at big
scales. That is the logical conclusion.

Just one thing. Matter could be organized at big scales by forces that
at our level of being (1.8 meters, 5 watts brain freshly evolved from
some primate) are undetectable by our labs and particle accelerators.
Those forces acting at galactic or cluster scales could be determinant
for our understanding of the cosmic web.

Matter seems to be connected everywhere, and the size and forces that
make those connections and filaments are unknown to us but they exist,
since those filaments exist. There are filaments between the stars, and
filaments between the galaxies, and filaments between the clusters of
galaxies. Rivers of galaxies can be figured out, and astronomers have
followed those filaments to figure out the biggest being they have ever
seen, an incredible structure that you can see he

Its filamentary structure is evident in this drawing.

Sadly, our ideas about a big bang and the resulting explanations make
this hypothesis not so attractive for many people.

Since observations indicate that a sea of galaxies extends away and away
from us in all directions, I consider that the CMB doesn't really imply
a big bang.

It is just that: Cosmic Background. The sea of galaxies is bathed in the
relic light from all uncountable galaxies extending till who knows
where. This explains why is so uniform.

Ambient light.
