Well, after thousands of words, you have proven to your own satisfaction and to mine that Birkeland's solar lab model and SAFIRE are like the Sun in that they are all approximately speherical.
Even *that* is more than your "stardard" model does properly!
https://www.independent.co.uk/news/scie ... 57068.html
Neither lab model has any other feature which represents the Sun's processes quantitatively.
What are you even talking about? It certainly does represent the process *physically*, and generates high speed particles which can be measured quantitatively in every conceivable way. All it takes is money and effort.
If you can point to any single aspect of Birkeland's description of his lab model, that gives us any quantitative insight at all into the underlying physical processes of the Sun that we don't already have from observations, I'll look at it again.
You didn't really "look" at any of his math as far as I can tell. What difference did any of it have on you personally in terms of the merits of his model, and why?
In such a case, you should describe exactly what Birkeland found, referencing the page number on which we find the description, and setting out what that means quantitatively at the scale of the Sun (so setting out voltages, currents, magnetic fields, temperatures etc, whatever is relevant to the specific insight you are claiming.)
I already pointed out to you that he estimated the voltage (based any scaling his lab experiments) at about 600 million volts. You trivially handwaved at that issue, along with all the quantified figures in his entire book.
I have just put four quotes together from your last post or two. When pressed to quantify the importance of cosmic rays to the Sun's processes, you go into obfuscation mode,
No, you went to mathematical dictator mode, *demanding* that I personally do your mathematical bidding! Get *over* yourself.
and pretend that it doesn't matter a jot so far as you are concerned in 4).
It ultimately *does not* matter to me personally whether the sun internally creates the majority of the "electrical tension", or the incoming cosmic rays cause the majority of the tension between the surface of the sun and "space". Birkeland's model is an *internally* powered model, so the *amount* of external current flowing into the solar system isn't even all that relevant to my personal preference for Birkeland's cathode solar model. I'm simply noting that we've already *measured* in space (flying electric ions), something which Birkeland 'predicted' a century ago based on "working simulations". His model doesn't just predict flying 'electrons' in the solar atmosphere, it's predicts that space contains most of it's mass in flying electric *ions* between the stars in space, and some of them are likely to be high energy particles.
But in 1), 2) and 3), you are in full Rotweiler mode, trying to belabour me with the importance of the cosmic rays, and accusing me of ignoring them.
You do ignore them in terms of explaining solar system processes. Your model treats "space" as being electrically neutral, when in fact it's high speed positively charged environment at the *fastest* scales.
You need to make your mind up as to whether they matter or not,
They matter in the sense that Birkeland's model ultimately predicts that space is full of flying electric ions, and the sun emits cathode rays, both of which are verified by satellites in space.
if they do matter you need to be able to articulate what exactly it is that they do, because as sure as the Earth turns you haven't done that yet.
They demonstrate two key "assumptions" that Birkeland made, first that the sun acts as a "cathode" with respect to something he called 'space', and it shows that 'space' is ultimately a non-neutral environment at it's fastest scales. Comic rays are *overwhelmingly* positively charged and nothing else carries current around the universe that fast.
Birkeland used the term "rays" with respect to positively charged particles too, and indeed we observe high speed ions traveling from the sun at nearly a 1/3 of the speed of light during some solar flare events, far faster than solar wind.
Now once and for all, I am not denying the cosmic ray flux.
Where did you 'factor it in" anywhere in terms of "physically* into your solar model? When you claim the sun's atmosphere is 'net neutral', how do you offset it?
I am trying to ascertain what importance you think it has in the Sun's processes, something that only you can tell me as it's uniquely your idea.
The concept that the universe is filled with flying electric ions is *not* my idea. Stop saying that! You're misrepresenting his model *entirely*.
Whatever the figure might be, I know for a fact that *mainstream* models essentially ignore it for all intents and purposes and never discuss the amount of "current" it represents in terms of net positive charges flowing into the solar system.
The first step in deciding if your idea has any merit is for you to articulate clearly what you think is going on with the Sun so far as the cosmic rays go. The second step is to take the known flux and to calculate whether it does what you think it does. Both of those are jobs for you.
I'm not a paid astrophysicist, so these aren't my "jobs" at all. They're simply mathematical busy work that you personally would like to see me do, not that it would even matter to you one iota in the first place.
If are unwilling or unable to do that, your repeated appeal to cosmic rays is not just impotent, but eventually becomes dishonest.
Woah. What's 'dishonest' is trying to dumb down the scientific importance of successful laboratory simulations over "hypothetical mathematical models". Your new and improved 3D "magnetic reconnection" mathematical models cannot and will not ever produce any *sustained* high speed particle movements, not a single one of those sustained processes which are necessary to produce full sphere solar strahl, solar wind, planetary aurora, etc. None of your MRx nonsense produces *sustained* particle physical processes in the first place in a real lab experiment! Doesn't it bother you that you can't even simulate a *sustained* planetary aurora based on MRx in a real lab experiment? How physically useless is your 3D math anyway?
The mere existence of light speed cosmic rays which are overwhelmingly positively charged, *falsifies* any solar model that treats "space" as being a "net neutral" environment, until and unless it accounts for anything that might "offset" that continuous flow of positively charged high speed particles into our solar system.
This is what Birkeland had to say about the Sun having a negative charge with respect to space:
"It is at present not easy to see how a negative tension should be continually created by the sun in relation to space.
A century ago it wasn't easy to see how a "negative tension' might be created and sustained. Now you have at *at least* two, and a couple more I can think of, to explain it, starting with cosmic rays and the "tension" they create. They're high speed positively charged particles which constantly electrically interact with our solar system.
What is the charge of "space" itself at it's very fastest scales (speed of light particles)?
It is of course possible to imagine that a surplus of positive ions is always being carried away from the sun
Well, we do measure positively charged ions, but you'd have to compare them to the movement patterns of electron strahl traveling at higher speeds than solar wind speeds.
or that negative ions are always being carried towards the sun,
We don't really seem to see a lot of evidence to support that, although it's possible that inbound currents return near the poles.
and that the negative tension is produced in this manner; and that the balance is maintained to some extent by distinct disruptive discharges, as we have presupposed."
About the *only* physical process you can hope to reproduce with 'magnetic reconnection', is a short duration "burst" akin to a 'disruptive discharge"/electrical discharge (Dungey) in a real lab experiment, but even that reveals the fact that you need *enormous* amounts of electrical current to produce them.
There is no mention here of space being positively charged, but only of the Sun being negatively charged,
“It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds.
The term "all kinds" of flying electric ions would certainly include 'cosmic rays'. How does your mainstream solar model handle that, and where does it predict it?
for which he proposes the mechanisms of positive ions streaming away from the Sun,
Yes, he presupposes that our sun *and every other sun* sometimes emits positively charged ions, sometimes (solar flares) with many times the kinetic energy of a typical strahl electron. I'm sure he's quite aware of the implications of the existence of other suns, which is why he's talking about "space" and it's electrical makeup.
If you look at it purely in terms of kinetic energy, you're going to create at least some solar flare events which emit positively charged ions at very high speeds, maybe even cosmic ray speeds in some instances. If all suns do that, then there's a "natural" explanation for it with Birkeland's model too. They're likely to hold and carry around *far more* kinetic energy than even a typical "strahl" electron from the sun, let alone a solar wind electron.
and electrons (or negative ions) streaming into the Sun.
The places we're likely to see that are places where the so called "open magnetic lines" actually return back to their point of origin. I'm sure the current flow patterns in the solar atmosphere are actually quite complex.
No mention of positive ions flowing into the Sun.
If space is full of charged particles, they all flow into and through our solar system. You seem to be trying to condemn him for not explicitly using the term "cosmic rays", instead of "flying electric ions of all types". Sorry, but your "legalese" with respect to his statements is absurd.
Even *if* Birkeland never imagined the implications of finding out that the fastest and most energetic charged particles in and around our solar system are overwhelmingly positively charged, that is something we know to be true today from the Voyager missions.
If you're trying to figure out how that "tension' is maintained, it might be important to know how much is "maintained" by the sun, and how much is maintained by cosmic rays.
Therefore, Birkeland's proposed mechanism does not involve positive ions flowing into the Sun (or being in the Sun's vicinity).
That's completely false. Birkeland was well aware that our own galaxy contained millions of sun, all contributing to 'flying electric ions', and any such environment produces a steady stream of charged particles flowing *into* our solar system from the outside. I don't recall him being aware that cosmic rays were overwhelmingly positively charged however, so I'm not sure how or if that figured into this model.
Have you actually read his book? You will note that he acknowledges that the source of the 600MV is not obvious.
Well, it's bit more obvious now IMO. It doesn't all have to be generated *internally* to start with.
You will also note at the conclusion of this section that he acknowledges that he has no viable proposal for the 600MV, falling back on a possible extension to Maxwell's equations which has never transpired.
What has transpired however is a much clearer picture of the solar system plasma movements, including the *higher* concentration of cosmic rays outside of the heliosphere.
Whether or not Birkeland could fully explain the existence of the field itself, he could certainly predict it's voltage. Astronomers have attempted to discuss the 'charge' of the surface of the photosphere only based on gravitational separation, but I can't recall them ever estimating the "charge' of space itself, other that to "assume" it's net charge neutral.
What "offsets" the cathode rays and keeps the sides of the box at a "constant charge" is the fact that the sides of the box are conducting and connected by a sodding great copper wire to one terminal of a voltage generator, the other terminal of which is connected by another great sodding wire to the metal sphere. There is no analogue of cosmic rays in the lab model.
Ya there was. Did you read the whole discussion about quicksilver particles sticking to the fat they put around the glass of the experiment. He demonstrated that not only was the cathode surface emitting electrons, it was emitting positively charged pieces of the cathode out into space.
His model specifically predicts that electrical discharges in stellar atmosphere can and do produce high speed ions, which flow *in* at the heliosphere, and out from the surface. Most if any of the net current flow won't be traveling at solar wind speeds, it will be traveling at cosmic ray speeds and solar strahl/rays/beam speeds.
It ultimately doesn't matter to me *how much* if any current might be coming into the sun from the galaxy since I assume that the sun is internally powered to start with. You're making sound as though the number that I come up with must have some great relevance to powering the sun. I didn't even suggest such a thing to start with, so whatever the number might be, it's not that important to me personally in reference to my preference for Birkeland's solar model.
There you go again, disclaiming the importance of cosmic rays.
There you go again making a *strawman* out of my statements. Sheesh. I didn't 'disclaim' their importance, I simply noted their importance and relevance to *all possible* solar models. Whatever solar model your heart fancies, it needs to include the net electrical effect of cosmic rays on our solar system.
The existence of cosmic rays, and the fact they are *overwhelmingly positively charged* is relevant to Birkeland's cathode model, just as it's relevant to any model. In his case, it could go a ways to explaining how and why that 600MV is maintained over time.
I really don't know what you think now. Do you think that they are important to the Sun's processes or not? If not, stop calling on them in your arguments.
Fully explaining that 600MV is pretty much a requirement of any cathode solar model, so in that sense it's important, but the exact figure wouldn't change my preference for a circuit based, charged surface based cathode solar model. Their mere existence only supports my preference for a cathode model IMO.
If yes, then you need to articulate and quantify what this importance is.
It's certainly a relevant *scientific* question, but if the number is *particularly* relevant to you personally, let's see your math.
It technically doesn't matter to me if the sun's produces most of the tension, but it's also quite clear a century after Birkeland, that cosmic rays are the fastest speed particles in the universe, they are *overwhelmingly* positively charged, so it would be *naive* to ignore that part of the kinetic energy and charged particle part of the process.
I don't even know what aspect of the Sun's processess you think depends on them.
Technically everything depends on their being a 600MV+ charge difference between the solar surface and a "space" that Birkeland describes as being filled with flying charged ions.
I did not think or say that you were claiming the Sun is powered by the cosmic ray current, but I don't know what it is you are claiming.
Well, I suppose I'm "claiming" that your precious 'standard' (electrically brain dead) model of the sun is "incomplete" because it doesn't account for them, or anything else in a real laboratory experiment.
I would also "assume" than any 'cathode' solar model would need to consider and incorporate them as well, so it has the same net effect on *all* solar models.
I don't understand why you so averse to putting numbers on the processes.
I'm not "averse" putting numbers any any process you'd like so long as *you're* the one doing the work. As I mentioned, Nereid personally burned me out on the "do my mathematical busy work" routine, when he handwaved at an afternoon of my time in a single sentence and promptly gave me another math assignment.
I personally think that astronomers try to mathematically intimidate anyone and everyone who disagrees with them, even (and especially) when the disagreement is over a *qualitative* claim being made, like the existence of dark stuff, or the belief that MRx produces *sustained* particle movement processes over extending periods of time.
I'd even do the calculation for you under certain conditions, but I don't even know what sum to do, because I don't know what it is you think is important and how that drives the solar processes. If you could, what would you calculate, and why?
What exactly do you wish to know and why? Which of Birkeland's mathematical presentations did you find compelling and why?
Again, I ask you quite honestly, and quite bluntly. Doesn't it bother you one bit when you read Birkeland's book that you are not able to recreate *any* of the *sustained* particle movement processes in the lab based on "magnetic reconnection"? Does that really not bother you, because it certainly bothers me. I've had a prefectly logical and rational explanation for that charged particle movement pattern since before I was even born, along with a comprehensive set of experiments and beautiful mathematical models based on circuit theory.
Frankly Higgsy I simply don't see how you rationalize away the fact that not only can you *not* simulate a sustained high energy process in the lab with magnetic reconnection. If Alfven hadn't called that whole concept pseudoscience it wouldn't be so bad, but he spent his entire career and lifetime applying *circuit* theory to events in space and he publicly rejected your beliefs.
I don't see any laboratory justification for even claiming that ordinary induction and magnetic reconnection are different physical processes in plasma. I certainly see nothing remotely like a "sustained" high energy process based on 'magnetic reconnection".
The fact you cannot produce these simple things in the lab is *damning* to your beliefs, and it always will be.
