While I tend to avoid arguements online, I enjoy reading the never ending debate about plasma and related issues. I keep learning new stuff.

If I may, I'll take you at your word, and in a later post I'll walk you through one aspect of the deep inconsistencies in "plasma cosmology" (at least as presented by Z, here in this thread). I shall try, hard, to keep the level sufficiently low that you can follow along, but I trust that you will respond in accord with the spirit of what you have written here, and ask questions about stuff you don't understand.

As promised.
Aim: walk robinson through one deep inconsistency in "plasma cosmology".
Scope: "plasma cosmology" as presented by Zeuzzz in this thread; specifically as presented in
post#684.
Key assumption: "plasma cosmology" is intended to be a major contribution to contemporary science, and assessed accordingly (this is, after all, the Science, Mathematics, Medicine, and Technology section of this forum).
Let's begin.
A central aspect of "plasma cosmology" is the following:
"
Plasma cosmology advocates emphasize the links between physical processes observable in laboratories on Earth and those that govern the cosmos; as many cosmological processes as possible are explained by the behaviour of a plasma in the laboratory."
This is entirely consistent with the Copernican Principle (crudely, the Earth does not have a special place in the universe), and a deeper principle explicitly used in modern physics (crudely, that 'the laws of physics' are the same everywhere in the universe).
No doubt you have heard of the General Theory of Relativity (GR), first published by Einstein in 1916.
This theory is universal in its scope.
It has been tested extensively, in laboratories on Earth, throughout the solar system, and beyond.
Clifford Will's "
The Confrontation between General Relativity and Experiment" contains a summary of those tests; you may find the most recent version of this document
here, and its arXiv abstract is
here. There is a huge amount of information and links and references and stuff there, allowing for investigation and study of stuff.
This next part is very difficult.
What happens when you take GR and apply it to the universe as a whole? I can give you lots and lots of excellent references robinson, but I know of none that present this application at a technical level suited to you.
When faced with these kinds of situations, what do you do robinson? How do you go about verifying for yourself that conclusions from using something beyond your technical level are sound, in terms of the science (this is the Science, Mathematics, Medicine, and Technology section of this forum)? If you could let me know, I'd be happy to walk you through how the conclusion follows from GR, using a method suited to you.
Here's one result: a scalar expansion is predicted from the FRW metric.
What does that mean?
In simple words, it means that the further an object is from us, the faster it will seem to be moving away from us. In other words, GR predicts the Hubble relationship. If you'd like to learn more about the Hubble relationship, may I suggest that John Huchra's website
The Hubble Constant is a good place to start? There is a huge amount of information and links and references and stuff there, allowing for investigation and study of stuff.
That completes the first part of my walk-through for you robinson.
"
a scalar expansion as predicted from the FRW metric is not accepted as part of this evolution"
Those are words from the source Zeuzzz quotes, in post#684, concerning plasma cosmology.
We may call this a central tenant of plasma cosmology, a core belief, an essential pillar.
Notice anything strange?
Recall this: "
Plasma cosmology advocates emphasize the links between physical processes observable in laboratories on Earth and those that govern the cosmos".
We are at the end of the walk-through; here is one deep inconsistency (or intolerable conflict) in "plasma cosmology": on the one hand there is clear statement of the Copernican Principle; on the other, an arbitrary exclusion of GR.
Now the extent of this inconsistency (or intolerable conflict) may take some time to sink in, so let me expand on it a bit.
The "not accepted" part of the central tenant of plasma cosmology is not only a denial of GR and all the experimental tests to which it has been subject; it is also a clear, unambiguous statement that the Hubble relationship must be wrong, that the distances or redshifts (or both) must be wrong.
So what? Well, for one thing, it makes plasma cosmology something other than science - it contains a core element that ought to be eminently testable (by observation and experiment) but which has been declared off-limits for any testing. It declares GR to be an illegitimate theory of physics, by fiat, by declaring that its stated scope (universal, remember) is false.
If you are a fan of Karl Popper, a robust conclusion is that plasma cosmology is not falsifiable, and so cannot be part of science.
No doubt you have many questions; if you would care to write them down, I would be happy to try to answer them.
