Well for starters you were lumping coronal loop duration into the exact same category as a "solar flare". They aren't the same duration. The coronal loops can and do last for days and weeks on end above "active regions", whereas solar flares are typically associated with short duration "electrical discharges" in the solar atmosphere as James Dungey first described it.Higgsy wrote: ↑Fri Dec 18, 2020 7:09 pmWhy not?Michael Mozina wrote: ↑Fri Dec 18, 2020 9:45 amScaling things like size, voltage, amperage and temperature might be relatively easy for us to agree on, but not necessarily "duration".
You seem like an intelligent individual, but when you say things like this, it's quite clear that you don't have a lick of common sense.I didn't say his life's work is of little or no value, and I don't think it. I said, and it's still there above for you to check, that "so far as Birkeland's solar lab model is concerned, any resemblance between it and actual observations is purely coincidental and of little or no value", and I stand by that.

Before you is a *working simulation* of not only *sustained* high speed (strahl) solar wind particles from the sun, but a planetary aurora, a solar corona, short bust "electrical discharges", in the solar atmosphere, cathode rays, etc. When you blow it off with nothing but a handwave, I can't help but realize that you've completely detached from what I would describe as "physical reality". Here's a particle flow pattern before you that *highly* resembles the solar atmosphere, and you're not even willing to put in any real time and effort into understanding it properly, and seeing how it applies to solar atmospheric physics today.
You can't even produce a *sustained* particle flow pattern of any sort with "magnetic reconnection" *without* sustaining the process with "electrical current". You can't simulate any of this based on what Alfven describes as MHD "pseudoscience' till the day he died. It doesn't seem to bother you one iota that your physically incapable of replicating of this with magnetism and MHD theory in a *real lab experiment*.
It is a 'ballpark figure' that is a direct consequence of pretty much everything he learned in the lab, and from the various in-situ measurements he took of the course of his lifetime. It's essentially the culmination of his lifetime's worth of hard, and often dangerous physical work and his lifetime of mathematical work.He calculated it on p665, using an oversimplified idea and making an ill-justified assumption about the Sun's magnetic field. It is not a consequence at all of his lab model so far as I can see.How do you figure he came up with various values (like solar voltage) that he posited?
I'm saying that you cannot begin such a discussion by proclaiming that coronal loops and solar flares are similar duration events! They're not.What makes you think duration is any different from the other parameters. Either you are saying only steady state phenomena are of relevance, in which case we can ignore all transient phenomena; or you are saying transient phenomena are relevant in which case you can't say anything about them from observations of the model, because you haven't observed the model over the correct timescales.
Without simulating fusion ("transmutation of elements") in the lab, Birkeland simulated every other relevant feature of solar physics and planetary physics, right down to the whole cause of things like aurora and "sprites" and such. You're *at least* a full century behind in the lab with MRx, compared to circuit theory. When are you going to embrace circuit theory Higgsy? You do realize it's an *equally* mathematically viable way to do physics, and it *works* in the lab?]No they absolutely haven't. No-one has ever in the history of the Universe ever modelled an entire Sun in the lab to any degree of accuracy.
Pure deflection and nonsense. My personal beliefs, and/or any calculations that I might personally whip up for you on command are *purely inconsequential* scientifically speaking. You can (and should) calculate them for yourself, *properly*. By properly I mean to figure out how much positive "current" we have flowing into the sun from the universe via cosmic rays, you'd have to calculate the *total flux* through the *heliosphere* (not at the solar surface) over time. The average speed and energy state of the cosmic rays as they enter the heliosphere would have to be considered.Well first of all you have repeated the claim that being bombarded by positively charged particles causes the Sun to be negatively charged at the surface (I have bolded your words above, so that people can see exactly what you wrote, so you can't accuse me yet again of making strawmen); and secondly, you are still obfuscating - I do not know, and no-one knows, what this "electrical interaction" between the Sun and the so-called positively charged space actually means in practice, whether it is significant or not, until you quantify it. Until then, you are handwaving.
Assuming the sun *is* gravitationally separated at the negatively charged surface as the mainstream assumes, you might be able to figure out how that positively charged current at the heliosphere is offset by "cathode rays"/electron beams (as NASA describes them) streaming away from the surface toward the heliosphere.
If you won't be bothered to do the work for yourself, don't expect me to be your personal math mommy on command.
No, it's not 'my' claim. Comic rays are *measured*, both here near the Earth, *and* out by both Voyager spacecraft, and the amount of cosmic rays *entering* the solar atmosphere has to be offset by the electron "strahl* electrons that rush out to meet them in the upper solar atmosphere. The cosmic ray flux is significantly higher in the 'upper solar atmosphere" (out by the heliosphere).Because this business of the cosmic rays is your claim, not theirs and this is about your claim, not theirs.
False. Birkeland made all sorts of "claims" and he made all sorts of "key assumptions" in his model, starting with a 'positively charged space" surrounding a "cathode" solar surface. His predictions are absolutely relevant, not mine. Why are you trying to *personalize* the conversation in the first place? I'm simply noting what we've learned from satellites in space over the last century.Still obfuscating. You have made a claim. Birkeland didn't make the claim.
Er, assuming even all of that were actually true, why would *my* beliefs and or math skills make a rat's ass of difference to you from a "scientific curiosity' perspective? Mathematically speaking, wouldn't you be more qualified to do that in the first place? What numbers do *you* come up with?Alfven didn't make the claim. It is your claim, and you should justify it. You keep bleating that "our whole solar system is being constantly bombarded by positively charged cosmic rays, traveling at near the speed of light.", and you also claim that means that space is positively charged wrt the Sun. I'm asking for your calculation to support your claim. Put numbers on the electric field generated at the Sun by the cosmic ray flux or by the charge density of cosmic rays near the Sun. The question is whether that flux leads to anything that is physically significant, or whether the absence of cosmic rays would make any difference at all to the Sun - until you quantify it, no-one knows. And if you can't quantify it, we can assume you're just blustering.
I see that you copped to your error with respect to my previous statements so I simply skipped that part.
Here's what blows me away Higgsy. *None* of your mathematical beliefs actually "work in the lab" to generate even so much as a sustained planetary aurora. Your 'dark matter' nonsense is about as metaphysical (unfalsifiable) mumbo-jumbo as it gets, and none of it is compatible with the standard model of particle physics, *the* single most successful physical model in the history of particle physics today.
Instead of lifting finger to educate yourself on these topics, you expect me to do it all for you. Why? Have you even read Birklend's *entirely* two set volume yet? Yes or no? Have you read Alfven's book "Cosmic Plasma"? Yes or no? Have you read Peratt's book "physics of the plasma universe" yet? Yes or no?
*These* are the best mathematical references I can think of Higgsy, so if the answer to any of those questions is 'no', you aren't really interested in the math in the first place.
