Plasma Cosmology - Woo or not

[Reality Check]

Zeuzzz: Thanks for the link to Peratt's "Electric space: Evolution of the plasma universe". It reminded me to read it again and find the following:

A galactic magnetic field of the order of B_G = 10^-9 - 10^-10T associated with a galactic dimension of 10²⁰ - 10²¹m suggests the galactic current be of the order I_G = 10¹⁷ - 10¹⁹A.
In the galactic dimensioned Birkeland current model, the width of a typical filament may be taken to be 35 kpc (~10²¹m), separated from neighbouring filaments by a similiar distance. ... may have an overall length between 35 Mpc and 2.5 Gpc with an average length of Mpc.

So now we know have an actual quote for the width and length of these galactic plasma filaments.

I do not have access to his "Synchrotron radiation spectrum for galactic-sized plasma filaments" paper but this proves that there is radiation and so it (and the filiaments) should be detectable. The abstract suggests that it is the CMB but this paper was published in 1990 (before WMAP) so needs to be evaluated again with the current data. I will asume that the synchrotron radiation spectrum derived is that of a black body at 2.73K but does the paper (or a later one) contain a power spectrum?

 

[DeiRenDopa]

I missed this the first time ... (I added some emphasis)

... snip ...

Up one more level; Peratt's supercomputer models of 'spiral galaxy formation'.

As an interesting intellectual exercise, I'm sure it was (and still is) quite fun. However, it's pretty clear Peratt didn't try very hard to test his model for consistency with real spiral galaxies (beyond a 'rotation curve' and some pretty pictures)

His model explains the origin and source of energy of double radio galaxies, the total magnitude of the radio flux observed, the measured flux density as a function of frequency, the observed isophotal morphologies, the spatially varying power law within a source, the polarization properties of the incoherent synchrotron radiation measured, and the lifetime and evolution of a source. See sections a, b, c, d, e, f and g in his publication "Evolution of the Plasma Universe: I. Double Radio Galaxies, Quasars, and Extragalactic Jets, which deals with each one respectively. And other sections of this addresses the formation of elliptical quasars, magnetically confined sheet electron beams we see in all galaxies, the emporal and spatial characteristics of the induction acceleration field, polarization and superluminosity, The induction accelerated Sheet Beam, formation of dust lanes due to the elliptical magnetic separatrix, and many other aspects. http://plasmascience.net/tpu/downloadsCosmo/Peratt86TPS-I.pdf (IEEE Transactions on Plasma Sci. Vol. PS-14)

Another publication, http://plasmascience.net/tpu/downloadsCosmo/Peratt86TPS-II.pdf (IEEE Transactions on Plasma Sci. Vol. PS-14) looks at;

... snip ...
The importance of electromagnetic
effects in describing both the bulk- and fine-detail
structure in the velocity curves of spiral galaxies is also
reported in Section V.
... snip ...

In Electric space: Evolution of the plasma universe (Astrophysics and Space Science, Volume 244) he expands on it further, comparing the H-structure of his galaxy model to what we observe in galaxies, just as predicted by the supercomputer, along with many other aspects, and in Plasma and the Universe: Large Scale Dynamics, Filamentation, and Radiation (Astrophysics and Space Science, Volume 227) he elaborated further on many other aspects also.

and heres another http://plasmascience.net/tpu/downloads/Peratt_RolePartBeams.pdf (Laser and Particle Beams, vol.6, part.3) and there are others...

So i'm really not sure why you said "it's pretty clear Peratt didn't try very hard to test his model for consistency with real spiral galaxies (beyond a 'rotation curve' and some pretty pictures)", this sort of comment just comes across as a bit naive... and bit of a hand wave to be quite frank...

... snip ...

Er, Zeuzzz, I don't quite know how to break this to you ...

... the papers you cite are either OT (my comment was about spiral galaxies, not the shopping list you recited), or quite consistent with what I wrote (pretty pictures - there is no attempt to match the scales between model and observation^, much less explain how his model test particles correspond to visual waveband emission from stars - and rotation curves). There is one aspect I had omitted (it is not, as far as I know, in Peratt's first paper on spiral galaxy rotation curves) - expected signatures of galactic magnetic fields in emission/absorption by diffuse plasma/gas, specifically, CIV (this is a quite interesting topic in its own right; Peratt needs CIV for his model to be consistent, yet despite years of searching, by lots of people, no convincing examples have been found).

But you see Zeuzzz, to go back to a point I made earlier, there's pretty firm observational evidence that spiral galaxies in general, possess (an incomplete list):

* a central bulge
* a nucleus
* a thin disk
* a thick disk
* a halo.

There is also pretty good observational evidence that spiral galaxies possess stars, with masses ranging from ~0.1 to ~10 sols. Ditto that the surface mass density (of the thin, and thick, disks) varies in characteristic ways.

Then there's the strong observational evidence on the velocity dispersion of the stars and ISM (in several phases), in the thin disk, the thick disk, etc.

And so on.

Yet for reasons surely known only to Peratt, he chose to ignore almost all these well-known, well-established observations (or interpretations, if you prefer).

Now waaaaay back in this thread, TubbyThin wrote about what an alternative needs to do in order to be considered viable, within normal science.

One of the things it needs to do is account for the sum total of ALL observational results within its domain.

In the case of Peratt's alternative, that means ALL relevant observations concerning spiral galaxies. He doesn't get to pick and choose and declare his alternative viable because is matches his arbitrary selections.

So, by conveniently ignoring whole swathes of stuff (read the papers, he doesn't once mention that there are a myriad other things his model needs to address, much less make an attempt at doing so), Peratt is simultaneously blowing a raspberry at astronomers and declaring that in his version of science, consistency is an optional requirement.

^ by the way, if he had tried to match (distance) scales, then his work would be completely trashed by full-scale acceptance of 'intrinsic redshifts' (if only because all his scales - including those within the MW - would turn to noise).

(emphasis added)

There are at least two: the Lerner one (or ones) that Zeuzzz cited way back when (they're available from his website), and one by Peratt and a grad student William Peter (though that may be the precursor, as it was published in 1988).

The one that does the best is one of Lerner's ... it claims an 85% match with the COBE SED (i.e. Lerner predicts something that's not quite a blackbody; his exact words are somewhat different, I think). No plasma cosmologist has ever published anything on the CMB angular power spectrum, nor even on the dipole (!). There are also no PC papers on estimates of the CMB temperature in high-z clouds, nor the Sunyaev-Zel'dovich effect, nor the CMB's observed polarisation, nor ...

I wrote several posts on this earlier in this thread ... Zeuzzz didn't even acknowledge any of them, much less attempt a response ("Every single concrete [PC] idea which has been put forward [by Zeuzzz or BAC] - of which there have not been many - has either been debunked [...] [Zeuzzz] runs away whenever he gets too thoroughly trapped." - I wonder who wrote that, and when?)

 

[zosima]

I just went on the Plasma Universe website and noted that they have a long list of Peer Review articles that support Plasma Cosmology. Of course none of the articles supporting the PC conclusion were published after 1996.

If we're going to resurrect dead scientific theories I have some favorites I'd like to nominate...Lets bring back Aether theory, or the belief that proteins carry heritable information.

 

[The Man]

Patent goat blather. The plasma state of matter at STP is only achievable with massive amounts of energy input. To the best of my knowledge, all of the microchips in my equipment were manufactured at or near STP. And no plasma involved The preponderance of research into the dynamics of plasma has been conducted at or near STP, whilst the bulk of matter in the plasma state exists in the rest of the universe...

Back on topic--or near to it.

Periodically re-examining the quality of our observations is not woo. It is the very essence of the scientific method.

It would be better if you were to expand the best of your knowledge. Production processes for the manufacture of microchips almost never involve STP (standard temperature and pressure), mostly significantly higher temperatures, both higher and lower pressures (including near vacuums) of various gasses and as mentioned plasmas.

Re-examining the quality of observations is not “woo” trying to introduce as an unknown, into those observations, a state of matter that it is our understanding and regular use of that makes our modern technology possible is “woo”.

 

[Wangler]

Thanks for this.

What I was really getting at is that CDM does not, necessarily, have anything to do with cosmology. Further, historically, it was not 'invented' to address any cosmological issue, observation, etc.

So, both logically and historically, CDM is not related to the contemporary cosmological models in the way your post stated (or inferred), nor in the way RC meant with respect to PC.

DRD, I accept your position, and this correction on my initial comment.

Keep in mind that current cosmology is married to CDM in certain aspects, which I think is what you were getting at anyhow.

 

[The Man]

Matter in the plasma state tends to emit radiation.

Who said “all plasmas emit radiation”?

So, who said all plasmas emit radiation?

The fact that you misrepresented what Reality Check said to create a straw man stumbling block was evident before.

From recent observations with our new instruments, it is becoming obvious that we know very little about plasma in space.

We know even less about magnetic fields and electric currents in space. The problem is observing something (that is very far away), that doesn't emit any radiation. We are limited to measuring and viewing secondary effects. .

So, you have no problem inferring things from their observable effects?

In a weird way, it is the same problem with black holes, that are not "feeding". Without something else interacting with a black hole, it is invisible. Same for plasma, electric currents and magnetic fields, all of which may be connected.

Of course this may be off topic, concerning plasma cosmology, which is still a nebulous topic.

Actually very much on topic, plasmas, electric currents and magnetic fields tend to be connected because plasmas tend to interact with and generate electromagnetic fields resulting in and from their tendency to emit electromagnetic radiation.

 

[robinson]

So, who said all plasmas emit radiation?

Nobody said that. I said, and I quote:

We don't know that much about plasma in space. Without experiments, we can't really say that all plasmas emit radiation.

See? I didn't say "all plasmas emit radiation", nor did anybody else. You said it, but as a question.

The fact that you misrepresented what Reality Check said to create a straw man stumbling block was evident before.

Only in your mind. What RC said was, and I quote:

Matter in the plasma state tends to emit radiation. This means that we can detect it and plug it into our calculations for the velocity dispersion curves for galaxies and the behavior of galaxies in galactic clusters.

Not only do some plasmas not emit anything, some are completely opaque to all radiation. Then there are the unknowns. Both in deep space, as well as within stars, there exist plasmas we know almost nothing about.

According to current theory.

During the first few days of the universe, the universe was in full thermal equilibrium, with photons being continually emitted and absorbed, giving the radiation a blackbody spectrum. As the universe expanded, it cooled to a temperature at which photons could no longer be created or destroyed. The temperature was still high enough for electrons and nuclei to remain unbound, however, and photons were constantly "reflected" from these free electrons through a process called Thomson scattering. Because of this repeated scattering, the early universe was opaque to light.

^WP
This is essential to the theory about the Cosmic Background radiation.

Of course some may try to call unbound electrons and nuclei something besides plasma, which is an interesting topic in and of itself.

When the temperature fell to a few thousand Kelvin, electrons and nuclei began to combine to form atoms, a process known as recombination. Since photons scatter infrequently from neutral atoms, radiation decoupled from matter when nearly all the electrons had recombined, at the epoch of last scattering, 379,000 years after the Big Bang.

^WP
Different authors describe it in different ways, but the general idea is that until the plasma reached around 3000K, it was opaque to photons.

Which is a bit hard to believe.

But this belongs in the other topic.

Another publication, http://plasmascience.net/tpu/downloadsCosmo/Peratt86TPS-II.pdf (IEEE Transactions on Plasma Sci. Vol. PS-14) looks at;

The gross radio properties of galaxies are reviewed in
Section II. Section III describes a transistion through the
following sequence of cosmic objects: double radio galaxy
to radioquasar; radioquasar to radioquiet quasi-stellar
objects (QSO's) [9]; radioquiet QSO's to peculiar and
Seyfert spiral galaxies; and peculiar and Seyfert galaxies
to normal and barred galaxies. The various classifications
of elliptical and spiral galaxies are discussed in Sections
IV and V, respectively. The importance of electromagnetic

It seems to me (please comment Zeuzzz) that there are two key Peratt papers, the two 1986 ones ("Evolution of the plasma universe. I - Double radio galaxies, quasars, and extragalactic jets", and "Evolution of the plasma universe. II - The formation of systems of galaxies") ... almost all the key points in the later papers are simply rehashes of what's in these two.

Now look at the "Electric space: Evolution of the plasma universe" paper ... the very last paragraph before the Acknowledgments ...

Notice something very interesting?

Nobody said that. I said, and I quote:


See? I didn't say "all plasmas emit radiation", nor did anybody else. You said it, but as a question. .

Actually you did, the phrase “all plasmas emit radiation” is right there in your quote as it is in my question. Are you now saying that you did not use those words?

Only in your mind. What RC said was, and I quote:

No, from what you wrote in an effort to communicate what was in your mind.

Oh that’s right I forgot about you preference for “dark postings” so we should not pay attention to what you do say but what you do not say. Well, wait, you said that you did not say “all plasmas emit radiation” so, that must have been what you meant when you did not say it.

Not only do some plasmas not emit anything, some are completely opaque to all radiation. Then there are the unknowns. Both in deep space, as well as within stars, there exist plasmas we know almost nothing about.

Why would that be hard to believe if as you assert.

But of course since you said it, means that you do not mean it. Now I understand why you find it “hard to believe”, which you didn’t mean when you said that anyway.

But this belongs in the other topic.

Are you sure you do not mean that?

 

[robinson]

That must be one of those dark postings. I can't see anything of substance, yet there it is, so it must mean something.

Or maybe it is a Dark Troll. A post that sucks so much, nothing can escape it.



I wonder which topic the question about opaque plasma should go in ... maybe yet another topic is required.

That's because the IEEE's copyright policy makes it hard for them to put up any papers from the most recent journals, you'll mainly only see ones from before 1998 online in full. Most of the interesting ones I've read are the most recent ones, from 2007 onwards.

[The Man]

I wonder which topic the question about opaque plasma should go in ... maybe yet another topic is required.

So you aren’t actually sure that you didn’t mean it when you said.

But this belongs in the other topic.

I do not know how much there would be to discuss on that new thread since your own post provided the reason for opaque plasmas, Thomson scattering.

http://en.wikipedia.org/wiki/Thomson_scattering

So it results from the plasma’s tendency to interact with and emit electromagnetic radiation. That “huge stumbling block of current physics” as you put it.

[Zeuzzz]

Um ... er ...

Did you see the leetle, teensy-weensy word "hypothetical" in there?

So, to clear this up, I was using a hypothetical (mustn't shout now) example that TT introduced, to myself introduce a general point ... before going on to make several specific points ...

So you have to use hypothetical inconsistencies with PC? why not just quickly list a real one, instead of one you make up? that way I can respond with what I think the answer is.

Whoosh!

Yep, that's the sound of the point I was making going right over your head ...

I asked if I had misinterpretted your statement, and this doesn't really resolve what you meant by saying "(I doubt there were many, if any, astronomers among those who reviewed his papers before recommending publication, for example)."


So your saying that no astronomers reviewed Peratts publications on his galaxy model? so there would have been no atsronomers at the Journal of Astrophsyics and Space Science? correct?

You mean to say that you don't (or didn't) actually read the material you cited?!?!?

HINT: try googling on "While this model has not been developed to the point of making detailed predictions of the angular spectrum of the CBR anisotropy"

Yes I have, but Lerner does not say what you did originally at all in that paper, to finish off that quote and the bit you missed out "While this model has not been developed to the point of making detailed predictions of the angular spectrum of the CBR anisotropy, it has accurately matched the spectrum of the CBR using the best-quality data set from COBE[27]. This fit, it should be noted, involved only three free pamenters and achieved a probability of 85%."

And you have to actually say why the angular power spectrum of the CMB is important and disproves PC, lack of explanation over one specific componet does not falsify the theory. The Big Bang does not explain, for example, how radio emmission is produced in the Jupiter-Io plasma torus, but that doesnt falsify the theory, as the Big Bang doesn't need to explain this.

Source please.

So, many thanks Zeuzzz ... although this is quite mangled, convoluted, and so on, it makes the point I stated very well.

Try this for size:

Some redshifts are 'intrinsic' ... but there's no PC theory/model/wild idea on which objects, how much (redshift), or anything else.

Nor is there an unambiguous way to derive the absolute value of any 'intrinsic' redshift, from observation alone.

Just search the text, it will pop up, and I said in that post its from Lerner. And commenting on them would be nice too, considering they are relevant to the subject at hand, and your responce widely was not...

This is yet another of the inconsistencies which PC proponents are quite happy to live with (an inconsistency between textbook statistical methods and observational analysis is small beer compared with full-scale acceptance of a mechanism not demonstrated in any lab).

There is no inconsistency. They have not said that any particular one is the mechansim, they have considered many of the possible alternatives than can explain the observed anomalies. Thats how science works. You dont just come up with your theory of what redshifts represent, and then say that this is it, no alternative should be investigated. And the mechansisms they have investigated have been investigated for the very reason they have been tested in a lab.

But you missed a very large part of the point .... the rather extreme inconsistency of trashing CDM (say) because no CDM particles have been observed in the lab while at the same time embracing without the slightest murmur of concern an idea that was not (at the time) backed by even the faintest hint of anything in the lab (and, subsequently, interesting ideas as you mention continue to fail ... no lab mechanism).

In everyday human interaction terms, this smacks of hypocrisy of the most egregious kind; in scientific terms, it is as blatant a declaration as I can imagine possible to make that serious inconsistency is quite acceptable as a core principle in PC.

CREIL is a directly testable phenomena, so is the wolf effect, and the others. Thats why they have been investigated by PC proponents.

Heres a few relevant to quasars and redshifts. I'm surprised you had not heard of CREIL, or the Wolf effect, so i'll provide a few links. And commenting on the above papers I quoted from Lerners website would be nice, or the heliospheric current circuit, or

The more you look into it, the more examples of inconsistencies, of different kinds, you can find.

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.

 

[Tubbythin]

So you have to use hypothetical inconsistencies with PC? why not just quickly list a real one, instead of one you make up? that way I can respond with what I think the answer is.

Nice way to dodge my question. I'll rephrase it.
What makes you think you have the right to criticize professional astronomers for not looking in to your supposed alternatives when you freely admit to being ignorant in the whole area?

 

[Zeuzzz]

Nice way to dodge my question. I'll rephrase it.
What makes you think you have the right to criticize professional astronomers for not looking in to your supposed alternatives when you freely admit to being ignorant in the whole area?

What makes me think I have the right? The right to have an opinion, maybe.

Just pointing out that there are other forms of energy other than nuclear fusion.

 

[Tubbythin]

What makes me think I have the right? The right to have an opinion, maybe.

Just pointing out that there are other forms of energy other than nuclear fusion.

Yeah. Some people used to think the Sun was made of coal. You wouldn't honestly suggest astronomers should spend their time considering the coal hypothesis would you? You have no models for alternatives to the p-p chain, just a few buzz words. And yet you criticize astronomers for ignoring your model-less buzz words. What makes you think your alternatives are any better than the coal hypothesis?

 

[Zeuzzz]

You have no models for alternatives to the p-p chain, just a few buzz words. And yet you criticize astronomers for ignoring your model-less buzz words. What makes you think your alternatives are any better than the coal hypothesis?

I critisise atronomers for seemingly not considering any viable alternative, from what I've seen. Either they have a reason to not consider them, or they should. I may be wrong, and if you know of any papers that rule out any other potential energy sources, or the various different fusion methods, then post it. I accept that the sun could be powered by H-fusion at its core, but as far as I can see it could also be powered by other energy sources aswell as this, I dont see why it has to be just one, you could have like Z-pinch fusion, electrical power, plasma focus, resitive heating, any of these could also contribute too. I dont belive directly any individual one of them over the other, I would just like to either see them ruled out, or at least considered. Thats my opinion.

 

[Tubbythin]

I critisise atronomers for seemingly not considering any alternative, from what I've seen. I may be wrong, and if you know of any papers that rule out any other potential energy sources, or the various different fusion methods, then post it.

There have to be alternative models first!

I accept that the sun could be powered by H-fusion at its core, but as far as I can see it could also be powered by other energy sources aswell as this, I dont see why it has to be just one, you could have like Z-pinch fusion, electrical power, plasma focus, resitive heating, any of these could also contribute too.

Ok, Z-pinch fusion is fusion at the surface right? I can rule that out immediately (and any other surface fusion). Surface fusion would not give the Sun a blackbody spectrum.
As for the others, provide a model and I'll have a look at it.

 

[Zeuzzz]

There have to be alternative models first!

Do there? How could science progress at all if people could only work on already existing theories?

And all the well known energy sources on earth provide the "model" so to speak, your just applying it in a different place than usually considered.

Ok, Z-pinch fusion is fusion at the surface right? I can rule that out immediately (and any other surface fusion). Surface fusion would not give the Sun a blackbody spectrum.

I find that explanation highly unlikely since the surface of the sun is not really dense enough for Z-pinch fusion. If the current density was higher than currently thought, then this would be a contendor, but it would be much more likely in the centre of the sun where the pressure and potential current can become high enough. But of course, we know that this one idea would not account for hardly any significant fraction, the sun would just implode inwards if all its energy was being created on the surface And its also very hard to imagine how convection functions in a completely surface powered star
