Then, for one particular supercluster or very large Messier object, Abell 2744, a cluster of galaxies, they find only 90% missing. The summary text: "The research shows that the majority of the missing ordinary matter is found in the form of a very hot gas associated with intergalactic filaments. doesn't seem to correlate with the main article title: "Warm-hot baryons comprise 5-10 per cent of filaments in the cosmic web." It does seem that the article's intent is to explain "missing ordinary matter" not "unscientific or hypothetical dark matter". Then, that could still just be a structure of the formation (active formation), or, a measurement artifact (of how much there is), or, well that's alternatives, and "intergalactic filaments" here are huge gaseous nebula in flow networks not "hairs".

Yes.

No. BB is nonsense. Guinness Book of records isn't science! (Only to
Wormley who thinks science comes from cartoons)

Space is not "flat". And space-time is not a real thing.

Dark matter is also bullshit a result of the errors in believing in the
BB which is itself a mistake by thinking red shift is due to velocity.

Big Bang is bullshit. No "first trillionth of a second".

One would expect it to be random as being noise generated by the entire
cosmos (not BB).

"precision cosmology" BWAHAHAHAHahaha! That is funny as hell Sammy!
Cosmology is all fantasy with no real data behind it anyway so you are
really extolling "precision fantasy"! Too funny for words!
Sam, you are STILL and ignorant idiot!

The mass of a particle isn't just refined, it's reduced. This is in part the measurement effect, similarly the deeper we look into the well the more the blinders there are, that then see yet more space and mass and then about how current models using "WMAP is flat" are off by 10^120 orders of magnitude (all the way off). Space's cosmological constant is an infinitesimal, particle size is like an infinitesimal point, all of space is like an infinite universe. Big Bang and Steady State both arise! Various galaxy surveys find them moving in all random directions, not just away. Then, given picking one or the other, then the evidence will support that either way, where both are true. It won't support neither. That's saying "Big Bang" and "Steady State" aren't exclusive. Look at NIST CODATA, particles sizes (as measured) halve every few years. "Running constants" and their ratio arrangements are becoming well-known in physics. Planck's c/C and 1/FSC aren't constants.

About Alma: those clusters are more than 11 billion
light years away, thus that view is 11 billion years old.
http://phys.org/news/2015-12-alma-monstrous-baby-galaxies-cradled.html
"The shape of the cluster observed by the Subaru
Telescope indicates the presence of a huge 3D web
of invisible dark matter."
"This finding supports the model that monstrous galaxies
form in areas where dark matter is concentrated. And since
modern large elliptical galaxies are simply monstrous galaxies
which have mellowed with age, they too must have originated
at nexuses in the large scale structure."
So, it seems the "dark matter" presence was computed off
the visible segment, then there's a difference with the radio
segment.
Why galaxy arms instead of galaxy rings?
http://arxiv.org/abs/1510.08861
"ALMA Deep Field in SSA22: A concentration of
dusty starbursts in a z=3.09 protocluster core"
From the abstract, about the "nexus" is about "at the
junction of the 50 Mpc-scale filamentary three-dimensional
structure traced by Lyman-alpha emitters (LAEs) in this field ...."
("We find that four of the eight SMGs host
a X-ray luminous active galactic nuclei (AGN). "
I think that's interesting because it's half of them.)
"The density distribution of dark matter is expected
to reflect that of baryonic matter and consequently
that of galaxies (e.g., Kauffmann et al. 1999)."
"Throughout this letter, we adopt a cosmology with
Ωm = 0.3,ΩΛ = 0.7, and H0=70 km s−1 Mpc−1."
Kauffmann, Colberg, Diaferio, and White: 1999 MNRAS?
arxiv.org/pdf/astro-ph/9906493
"In figures 15-17 we show fits to the data obtained
for the popular ΛCDM cosmology (Ω = 0.3, Λ = 0.7,
H0 = 70 km s−1 and σ8 = 1). We note that quasar
luminosity functions in the literature are almost
always computed assuming a cosmology with q0 = 0.5
and H0 = 50 km s−1. In order to avoid having to re-analyze
the real observational data, we choose to transform our
model predictions to the values that would be obtained
if the observations were analyzed assuming an Einstein-
de Sitter universe with Hubble Constant h = 0.5. Because
structure forms earlier in the ΛCDM cosmology, galaxy-galaxy
merging rates are substantially lower at z = 0 than in the high-
density CDM cosmology. As a result, we do not require an very
strong evolution in the cold gas content of galaxies to reproduce
the strong decline in quasar space densities from z ∼ 2 to the
present day. Our best-fit model has α ∝ (1 + z)−1 and tacc(z = 0)
= 2.5×107 Gyr. In addition we assume that tacc scales in the same
way as the host galaxy dynamical time in a ΛCDM cosmology: tacc
∝ (0.7+0.3(1+z)3)−1/2 (Mo, Mao & White 1998). As seen in figures
15-17, the ΛCDM model can simultaneosly fit the evolution of cold
gas inferred from the damped systems and the decline in quasar
space density from z = 2 to the present day."
Oh, so you just adjust the parameters to fit the model, how neat.

More on "why galaxy arms instead of rings",
just some Wiki-fodder, basically that spiral
is the way of galaxies, then as of why.
https://en.wikipedia.org/wiki/Spiral_galaxy
https://en.wikipedia.org/wiki/Hubble_sequence
There's a lot to be understood in this about
the fractal (self-similar at any scales), about
why barred spiral galaxies are like digital ones
and pinwheel spiral galaxies are like analog ones.
This isn't so much about explaining the missing
ordinary matter so much, as yet: how are spiral
galaxies formed, and, of the various sorts why,
then, is it usual for all galaxies to be spiral
galaxies, then, why variously barred and pinwheel
spiral galaxies.

Pinwheel spiral galaxies purpose is to propell more stars.

Imperial thinkers know that the entire universe and everything in it is
made of only AETHER! It's THAT simple. So simple even you and Wormley
can understand it!
