Plasma Cosmology - Woo or not

So it would be silly to say one ice cube has less water then a smaller ice cube, since frozen water equals ice and saying water has less water is just silly.

If you tweak that example a little, you could actually use it to make a point.

Two cups of water, which are equal in mass (the amount of molecules), have different amount of energy, because one is warmer than the other.

Or one is higher than the other, meaning it has more potential energy (due to gravity).

Or something like that.
 
A different point, mind you, but a point none the less.

So what was your point in that tweaking exercise, other then opposing your previous point? Is it that you just wish to remain pointless?

Or is your point that you would prefer to describe the universe using cups of water instead of math?
 
I don't know. How did we go from woo bashing plasma cosmology to discussing quantum theory?
 
Inventing a new form of energy is not the same as correcting a theory.

Well, in the real world that is. In the theoretical world where people just make stuff up, I guess some people think inventing an entire new form of energy, that has no relation to existing concepts of reality, some people imagine that is "correcting a theory".

Like when people imagined there was an invisible planet to explain the orbit of Mercury.
It need not be a "new" form of energy. It could be the good old cosmological constant that originally appeared in General Relativity. Dark energy is a placeholder for whatever is causing the extra acceleration of the universe.

Evidence for Intrinsic Redshifts in Normal Spiral Galaxies
http://www.springerlink.com/content/u52qh80262484j07/
Actually, this is quite different from the others ... and resembles an Arpian paper or two on the intrinsic redshifts of satellite galaxies (in the Local Group, and beyond), and certain 'interesting' (shall we say) explanations of the 'fingers of god' in some plots of the redshift distribution of (rich) cluster galaxies.

If the findings reported in these papers are taken at face value, then we would have thousands to millions of stars - plus gas, plasma, and dust - over extended regions of the sky (many, many times the angular resolution of the relevant telescopes), in wavebands from x-ray to radio ... all with the same (or very similar) 'intrinsic redshift'!

Not only has no 'plasma cosmologist' predicted such a thing, using lab-verified plasma physics, but none has even hinted that any plasma physics-based explanation might even be possible*.

Given the 'actualistic' philosophy that supposedly underlies PC, this should have provoked a crisis ...

... snip ...

And I've just noticed another engenius tactic you continually use DRD. Scientific publications dont have to be consistent, people form hypothesis and test their hypothesis, most separate scientific hypothesis are inconsistant. I could go through all the twenty completely different explanations that have been provided for the heating of the corona, and the acceleration of the solar wind, and keep claiming, like you do, "The fact that all the theories are not consistant with each other is as blatant a declaration as I can imagine that serious inconsistency is quite acceptable as a core principle in Solar physics" And I could do this in any other area of science too. So please refrain from perpetuating this argument, as it demonstrates a severe lack of understanding of how science works.
This is worth exploring further, in some depth perhaps.

IF all PC can be reduced to a number of independent hypotheses, models, theories, ideas etc (hmti), then what value does giving them all a single label ('plasma cosmology') add?

Further, as you have pointed out (implicitly, if not always explicitly), many of the various hmti have been worked on by people who do not seem to come from a plasma physics background, and/or do not seem to make links with PC (explicitly or implicitly), etc; how then can they be said to be 'PC'?

... and there would thus be no point to this thread ('PC' would not be 'woo', nor 'not woo', nor anything other than a label in search of a home).

HOWEVER, if PC is supposed to be some kind of coherent, unified, consistent agglomeration of hmti, then we can examine it from the perspective of normal science, and see if it does have internal consistency (for example).

ON THE THIRD HAND, we could go up a level, to 'philosophy', and use Alfvén's 'actualistic vs prophetic' distinction to examine all the various hmti you have presented, with the objective of assessing the extent to which they are 'actualistic' (the hall-mark of PC), 'prophetic' (the sign of non-PC), both, or neither.

------------------------------------------------------------------

re the first (IF): While there is, no doubt, more to discuss on each of the hmti you have presented, it seems to me at least that most are inconsistent with relevant (astronomical) observations, some look promising to good .. but we don't need a single thread to look at them all, do we.

re the second (HOWEVER): Myself, I can't see what else there is to discuss; PC is woo, because the ~half dozen major areas that it comprises (per an RC summary recently) are hopeless inconsistent, both with each other and with relevant observations.

re the third (OTTH): Though there's been little discussion of this, I think it is quite easy to show that PC is hopelessly inconsistent in this respect too.

* that I know of; if anyone has a paper that says otherwise ...
 
Inventing a new form of energy is not the same as correcting a theory.

Then pray tell, what is "correcting a theory" if not inventing something new ?

In the theoretical world where people just make stuff up

It seems to me like you have no idea what science really is. What do you think a theory does ? It's a hypothetical construct that is designed to illustrate how something happens. The exact "what" or "why" is irrelevant, because it has no operational value.

Like when people imagined there was an invisible planet to explain the orbit of Mercury.

Which was entirely sensible until they added relativity. I.e. SOMETHING NEW.

My post on the definition of PC as a collection of theories perhaps did not make it clear about the nature of the collection: This collection allows the addition of any new theory that matches their criteria regardless of consistency with existing theories in the collection. Thus they allow:
  • Multiple inconsistant theories on cosmological redshift.
  • Multiple inconsistant theories on the cosmic microwave background.
  • Multiple inconsistant theories on the structure of the universe.
It is the first time that I have seen the term "concordance cosmology" and I cannot even find a definition for it on Google. The papers that I can find just look like Big Bang theory.

Expanding the PC collection to inclde DRDs extract from this thread:
  • Peratt's plasma model of galaxy formation.
  • Lerner's model of element formation in galaxies.
  • Tired-light explanation of cosmological redshifts.
  • Intrinsic redshifts from the ejection of quasars from bright galaxies.
  • Other theories which may include the Electric Universe (e.g. electrically powered stars).
  • Lerner's explanation of the CMB (there's a Peratt one too, but it hasn't been introduced yet)
  • Peratt's ideas on quasars/QSOs/radio galaxies/AGNs (only tangentially referenced)
  • Various ideas on fractal scaling, up to ~tens of Mpc
  • Something about 'force free filaments' (unclear whether this is a separate idea or an essential part of one or more of the above).
  • Also the original Plasma Cosmology of Hannes Alfvén?
  • etc.
Time to take stock.

There may be additions to this list, and some items could certainly benefit from some editing, for precision, accuracy, and clarity.

There are also some, on this list, which have not been fully examined, so far, in this thread.

However, it is clear - to me anyway - that there are many inconsistencies between these various hmti's, with relevant observations, and so on.

Further, so far, neither Zeuzzz nor BeAChooser has addressed any of these inconsistencies*.

Now the mere existence of inconsistencies doesn't make something with a grand scope, like 'plasma cosmology' (PC), woo ... the woo comes from the proponents of PC not even acknowledging that there are inconsistencies, much less being concerned about them, engaging in a research program to address them, etc.

I have asserted that 'PC is the very definition of woo' several times now, and only Zeuzzz has responded to my assertions. How about some comments from other regulars in this thread? What say you? Does this approach to inconsistency - of many kinds, at many levels - make PC woo by definition? Or not?

* OK, maybe one or two, to some limited extent.
 
If anyone is interested, I'd be happy to run the 'electric stars' idea to ground (doesn't have to be Zeuzzz, who seems to be concentrating on swotting for his exams now).

I'm waiting for Zeuzzz to respond on hydrostatic equilibrium.

In parallel it may be fun to look at how the masses of stars (in the restricted sense I described above) can be estimated. Also, how their 'luminosities', or total power output (energy per unit of time), are estimated; ditto their shapes and a measure of their size (radius, say).

That will give us an 'absolute' HR diagram or two, and highlight the differences between 'normal' stars, white dwarfs, and neutron stars (including pulsars and magnetars).

We would then have some pretty good, agreed, derived 'facts' about stars; we could then use these to tackle the 'electric star' idea.

I've been keeping a loose eye on this (and related threads), and would be surprised if the electric star theory is taken seriously by anyone! but then I may be biased and a run-down may be good for onlookers. Besides, it's been a while since it was discussed at length.

Now who was saying main-stream physics avoids using the word 'plasma'? Just a couple of examples...

Vourlidas et al. First direct observation of the interaction between a comet and a coronal mass ejection leading to a complete plasma tail disconnection. The Astrophysical Journal, 668: L79–L82 (2007)

Tripathi et al. Density structure of an active region and associated moss using Hinode/EIS. Astronomy & Astrophysics, 481, L53–L56 (2008). Available for free here.
1st line of the abstract:
Studying the problem of active region heating requires precise measurements of physical plasma parameters such as electron density, temperature, etc.
And no, that's not because they suspect an 'electric Sun' :rolleyes:

The plasma cosmology types really should stay away from solar physics if they wish to have a floor to stand on...

Many thanks to those of you who have taken the time and effort in these threads. If they're still going in a couple of months, I'll try to help (then I'll hopefully be able to add a false appeal to authority by saying I'm a doctor ;)).

I'm not even sure exactly what the electric star argument is.

Here's my take. They claim that electrostatic repulsion balances the force of gravity within a star. Because the repulsive force isn't due to nuclear repulsion, fusion must be created by z-pinches that occur due to plasma dynamics around the star.

I've also heard the claim that an electric star is one that is created by some electromagnetic effect in the pre-stellar molecular cloud, rather than by a gravitational effect in this cloud.

Are these correct statements of the theory?
I'd like to know if I understand what these people are saying before I criticize it.

Here are the posts, in this thread, where Zeuzzz has presented this idea:

#448
#454
#472
#484
#485
#490
#536
#572

I may have missed a post or two, and not everything in all these posts is directly relevant to 'electric stars'; I have omitted the several posts, by others, which included questions to Zeuzzz on this idea (many - most? - such questions remain unanswered).

If you know of any papers which can account for various HR diagrams, quantitatively, by derivation from any 'electric star' model(s), please let us know (Zeuzzz was silent on that topic).
 
Way back in post #85 of this thread sol invictus wrote:
The trouble is that there is no such thing as plasma cosmology. There is a set of ideas, ranging from the totally ridiculous (the sun is powered by electricity) to the merely stupid (flat galactic rotation curves can be explained by electromagnetic forces) to phenomena not fully understood by anyone (solar flares) to the totally mundane (most matter in the universe is plasma).

Every single concrete idea which has been put forward - of which there have not been many - has either been debunked or turns out to be consistent with mainstream astrophysics. After the fact, Zeuzzz has then declared that those ideas weren't PC after all. Every attempt to get him to produce a concrete or quantitative prediction of PC has failed, largely I think because he recognizes that it will probably be shown false in short order, leaving him with few options.

So instead he continues making vague statements about PC, and spends most of his posts attacking aspects of the standard cosmological model (relying on the logic of false dichotomy: if the standard theory is wrong mine must be right - even though I don't have one).

He runs away whenever he gets too thoroughly trapped.
For example we had a long discussion on magnetic reconnection - a standard and well understood phenomenon which he claimed violated Maxwell's equations. Since this was an extremely clear example, I decided that it would make a good test. If Zeuzzz couldn't learn or admit he was wrong about that, he never would about anything and there wasn't much point in conversation. After months of being bludgeoned with irrefutable experimental, theoretical, and numerical evidence, he had totally reversed his position - while denying he had changed at all. When confronted with proof in the form of his own old posts (internet fora are nice that way) he ran away, and has only been back rarely since.
(I added some bolding)

And so history repeats itself; or, as ben m put it, Lather, Wash, Rinse, Repeat.

I've been curious about why it's so hard to get hold of the landmark PC papers by Thornhill, W. W. that Zeuzzz has referenced several times. You'll readily recall his style: sweeping generalisations about paradigm-shattering discoveries, followed by some quotes that don't seem to say anything much and many links. If you follow the links and read the papers (if you can), keeping Zeuzzz' posts on hand so you know the context, you'll be nearly always in turn frustrated, disappointed, and amused; Zeuzzz' case is, in almost all his posts, a strange mixture of waffle, ignorance, and cynical deception.

Here's a good example:

Shortly after Zeuzzz introduced 'electric stars' as yet another part of 'plasma cosmology', I asked this simple question: "Q: In which publications (papers) can one read "the electric star interpretaion of the hertzsprung russell diagram"?

After several exchanges of posts, filled with vintage Zeuzzz waffle, word salad quotes, and ignorance, I asked the question again, with a rider:

Comment: the paper(s) should explicitly discuss the HR diagram, and quantitatively address the observed colours, luminosities, and masses, by a direct derivation of these observables from the 'electric star' model (or theory, or ...).

If there are no such papers, to your knowledge, please say so."


Zeuzzz' reply is yet more classic Zeuzzz.

And my final attempt to get an answer, here, is where Zeuzzz ran away.

But why didn't he simply answer the question?

I think the reason is his cynical deception (or perhaps his ignorance) ...

Take The Z-Pinch Morphology of Supernova 1987A and Electric Stars, for example, from which he quoted in an earlier post.

This document is quite difficult to get hold of (or it was for me), which is perhaps just as well, given how awful it is.

It does, as Zeuzzz stated, contain a section on the HR diagram ("X. Hertzsprung-Russell
Diagram"), and another five directly related to it.

It also does, as Zeuzzz stated, relate the HR diagram to the (or an) "electric star model".

However, contrary to what you'd expect to find for an academic, technical paper in a physics journal, there are no equations, no numbers, ... and no model! :jaw-dropp

Worse, Thornhill includes a figure (two actually) that even undergrad students would get an "F" for ... it has a grossly misleading axis label*.

In short then, Thornhill's paradigm-shattering "model" is a waffly word-salad supported by a sloppy figure. Oh, and his list of references includes a couple of articles from KRONOS, several press releases, articles in Scientific American, New Scientist, some popsci books, commentary (not papers) in Science ... and Scott's crackpot book! One can only wonder who the reviewers of this so-called paper were.

I guess the most charitable interpretation you could give to this is that for Thornhill 'science' is done quite differently; certain requirements on rigour and precision are optional (to take just one aspect).

If it were just Thornhill, who cares?

What's more distressing is that this awful paper got published in "IEEE Transactions on Plasma Science" - do the editors not care? Or did Peratt somehow 'help'?

(to be continued)

* If you're curious, it's Figure 9; the x-axis, at the bottom, is labelled "CURRENT DENSITY AT THE STAR'S SURFACE (Amps/m2)", with a big arrow; there are no numbers, even though the axis has tick marks. The same axis is also labelled "(Spectral Type)" as well as "(color)".
 
Well that seems to be a general pattern for all wooish posters (IanTresman excluded) of the PC/PU. they make bold claims , they make false dichotomies, they swear up and down that have an answer but then they are just like creationists.

When push comes to shove they get coy, opaque and obtuse. they refuse to answer direct questions and then claim that they have.

Zeuzzz claimed that the EM force provides a 'semi rigid' framework that has some effects on the rotation of glalxies but he still has yet to present an object (other than a whole galaxy) for which he claims that his preposed theory will work.

As in the case of BAC, all flash substance and pitiful breast beating martyrdom, but no facts, no data. No nothing.

It is a 'cosmology' of the gaps. A vertible 'insert miarcle here' sort of thing, except they haven't got equations before and after the miracle.

Thornhill is a fraud apparently and so is most plasma cosmology.

They besmirch the name of Alfven and Perrat and then act all smug in thier ignorance.

Take Zeuzzz' 'agnosticism' on solar radiation, he can't provide a means, he can't provide a method. he can't provide the data. And I am sure that if wwe actual look at his abberant spectra, that is what they are, just as he cites paper's by Perrat that have been disproved by COBE.

This is truly classic woo
And I listed just a couple of direct observations that disprove the curent nuclear interpretation of the spectra, and support the electrical interpretation. There are many, many more examples like this of these 'variable stars' that are better explained with the electrical interpretation, rather than the nuclear one based on million year cycles.
Don't give the data, play coy and act like you have, but the actual reference? Not there.

I am not sure that Zeuzzz believes in all of this Electric Cosmology nonsense. It looks like he is literally quote mining it to support his ideas. But he must know that the fusion model of stars not only matches that actual obsevations of the Sun (e.g. the measured neutrino flux) but also provides the mechanism behind stellar evolution and the HR diagram.
Quoting Thornbill as a support for electrical phenomena on stars is a big mistake given what you have found.
 
I best go back to my lurking, but perhaps this is the nonsense that Zeuzzz loves so much:

http://www.electric-cosmos.org/hrdiagr.htm

and this puts lies to some of that nonsense:
http://www.google.com/search?hl=en&q=FG+Sagittae+&btnG=Google+Search
The first link is interesting ...

In the IEEE 'paper', Thornhill credits Scott for his second 'HR diagram', and cites Scott in his references.

It will come as no surprise to regular readers of this thread that the two accounts (the webpage DD gives a link to and the Thornhill IEEE 'paper') are remarkably similar ... and equally lacking in any physics (beyond the handwaving, word-salad level).

And it will also come as no surprise that both accounts of the HR diagram contain numerous errors, omissions, mis-statements, and so on*. No doubt many of these are not the least unintentional or due to ignorance (though some probably are), but are coldly calculated and cynical, deliberately intended to deceive.

* such as? You have only to ask!

So your not going to comment on the nonsense? Just declare it as such without a reason.

And why on Earth does your search prove anything? you should have just used the link that I myself provided previously, where you can see many variable stars, here; http://www.aavso.org/vstar/vsots/

From what I've seen only ad hoc theories and new physics have been invented to explain these enigmatic variable stars. Often with completely different causes for each one. The fact is that they are direct observations that conflict with the long time life span needed for stars using the billion year nuclear cycle. So an alternative interpretation of the HR diagram that would enable the spectra to vary this quickly in such a short time period would be supported by Each variable star observed, as no new theory needs to be invoked to explain each of them. And there are many. I only listed a couple, the one you searched for is the most well known.

And indeed, your search comes up with a very interesting paper in relation to variable stars, which seems to add further evidence for their spectra not being a direct indication of the nuclear cycle, but related to surface phenomenon.
A complex planetary nebula surrounds the weird star FG Sagittae The nebula makes the star appear fuzzy, and this is a well known effect in other variable stars.

Most variable stars have odd surrounding nebulae, implying that the spectra of these stars is affected by external factors. Which certainly adds credence to Thornhills model that the spectra could be related to other events, such as the current density on the stars surface, which can vary suddenly and unexpectedly depending changes in the stars local environment and the density on its surface, such as moving into an area of dense nebula.


http://www.weblore.com/richard/fg_sagittae.htm
More puzzles plagued astronomers as they began to measure the spectrum of FG Sge. In 1955 spectrograms showed FG Sge to be spectral type B4. By 1960 FG Sge had advanced to B9, and in 1967 it had reached A5 !! In 1972 it was spectral type F6, by 1980 it had reached G9 and by 1992 it had reached K2. These rapid changing spectral types indicated that FG Sge's temperature was plunging - falling by nearly 3 OO'K per year !! The star appeared to be expanding enormously - from 10 times the radius of the Sun in 1958 to over 55 solar radii in 1973. FG Sge changed from a hot blue star to a moderate temperature yellow star in just 20 years. [..]

In July 1994 there was another surprise: a rapid brightening observed was attributed to a new outburst of material. Analysis of absorption line profiles in its spectrum showed mass loss rates of about 3 x 107 M¤ /yr. It could be that multiple ejections take place before a rapidly evolving star such as FG Sge calms down.


Or the rapid brightening could be due to local changes in the current density on the stars surface.

Instead of inventing new standalone theories like 'helium shellflashes', or any of the other things usually used to explain these observations, the alternative explanation of the HR diagram can explain these observations with no problem, no new theories and epicycles needed. Thats why I think that this approach could have merit over the usual one.

What do you mean we haven't got equations? What equations do you want?

Why do you say this?

Take Zeuzzz' 'agnosticism' on solar radiation, he can't provide a means, he can't provide a method. He can't provide the data.


Data for what? Do you understand what agnosticism is? I dont have to quantify an alternative, I just dont have to fully belive the nuclear one is set in stone.

Anything on the sun that is subphotospheric should be treated as theory. Such as the various dynamo theories and others. A lot of the things attributed to the illusive solar dynamo could be explained equally well by a more electrically dynamic star, in line with plasma cosmology publications on the sun, such as current disruption causing solar flares, inflow events, coronal holes, plasma torus generation, birkelands electrical experiments, origin of solar magnetism, etc.

You are probably taking the more unorthodox electric star claims, such as very high charge, electrical power instead of nuclear, etc, which you wont find published in any PC journal.

Now who was saying main-stream physics avoids using the word 'plasma'? Just a couple of examples...


It is ever becoming an increasing area of study, and there are many publications that use plasma now. But they often use pseudoplasma which has mathematical elegance, but does not describe the full set of properties that plasma are known to exhibit as deduced by the experimental method. PC proponents prefer to use plasma scaling from laboratory to space, using the real experimentally verified properties of plasma. Such as these, which are a very small fraction of the papers on this subject published in plasma cosmology journals;

This is the key aspect of PC, gaining knowledge of the plasma in space via direct plasma based experiments and scaling them up through many orders of magnitude. This way we can gain an incredible knowledge of how bodies in space function by creating scaled down versions in the laboratory. It all started with the work of Birkeland and his invention of the Terella, and has been continued ever since by various PC proponents in their models. The implications of scaling laboratory experiments to space has been severely overlooked from most gravitational models. The only group that seems to see the merits in this approach are plasma cosmologists, and recently a few other journals and scientists are paying attention to this approach. This thread has mainly been discussing just two tiny areas in the entire field of plasma cosmology, Lerners various models and Peratts galaxy models, with a few other theories too. Not many PC publications have been discussed past their work so far here, I find the experiments the most interesting personally, as the more we find out the more accurately we can try to re-create space phenomenon in the lab. We may beable to create a mini plasma based galaxy in the future, that would be really cool.

See this publication, hot off the press, for a good overview of this area of scaling experiments in plasma from lab to cosmos: Interrelationship between plasma phenomena in the laboratory and in space - Jun 2008, Plasma Phys. Control. Fusion 50 070201(2p)

Many advances in understanding space plasma phenomena have been linked to insight derived from theoretical modeling and/or laboratory experiments. Observations from space-borne instruments are typically interpreted using theoretical models developed to predict the properties and dynamics of space and astrophysical plasmas. The usefulness of customized laboratory experiments for providing confirmation of theory by identifying, isolating, and studying physical phenomena efficiently, quickly, and economically has been demonstrated in the past. The benefits of laboratory experiments to investigating space-plasma physics are their reproducibility, controllability, diagnosability, reconfigurability, and affordability compared to a satellite mission or rocket campaign. Certainly, the plasma being investigated in a laboratory device is quite different from that being measured by a spaceborne instrument; nevertheless, laboratory experiments discover unexpected phenomena, benchmark theoretical models, develop physical insight, establish observational signatures, and pioneer diagnostic techniques. Explicit reference to such beneficial laboratory contributions is occasionally left out of the citations in the space-physics literature in favor of theory-paper counterpartsand, thus, the scientific support that laboratory results can provide to the development of space-relevant theoretical models is often under-recognized. [....]

The interrelationship between laboratory and space plasma experiments has been cultivated at a low level and the potential scientific benefit in this area has yet to be realized. The few but excellent examples of joint papers, joint experiments, and directly relevant cross-disciplinary citations are a direct result of the emphasis placed on this interrelationship two decades ago. Building on this special issue Plasma Physics and Controlled Fusion plans to create a dedicated webpage to highlight papers directly relevant to this field published either in the recent past or in the future. It is hoped that this resource will appeal to the readership in the laboratory-experiment and space-plasma communities and improve the cross-fertilization between them.


Now thats going to be one hell of an interesting Journal special issue when its published. And I suspect that nearly all of the publications will be from PC proponents and plasma cosmology journals, mainly IEEE transactions on plasma science, Laser and Particle Beams, Selected articles from Astrophysics and Space Science, IEEE Journal of Pulsed Power, etc.



Vourlidas et al. First direct observation of the interaction between a comet and a coronal mass ejection leading to a complete plasma tail disconnection. The Astrophysical Journal, 668: L79–L82 (2007)


That is a very interesting publication that I've seen before. That tail coming detatched was certainly unexpected for standard cometary theory, and a very interesting observation. Probably deserves a thread in itself.

The plasma cosmology types really should stay away from solar physics if they wish to have a floor to stand on...


Do you know any of the PC models for various solar physics phenomenon? What’s your main objection to them?

Many thanks to those of you who have taken the time and effort in these threads. If they're still going in a couple of months, I'll try to help (then I'll hopefully be able to add a false appeal to authority by saying I'm a doctor ;)).


Your contributions will be appreciated, no doubt. Just dont fall into the trap that other people have here of vigorously opposing something before they have the slightest clue what it is.
