So they are essentially a "current carrying" thread?
Yes, what else would they be, what is the last time you read a mainstream paper on coronal loops?
How do they "go in" exactly, and where do they "go in" again? I only observe them as partial loops just as in Birkeland's experiments. You folks seem to think we can't even see them until they reach the corona.
Have you ever looked at a picture of a coronal loop? Why do you think it is called
loop? At one point the field lines come out of the "surface" (and I use the term loosely) of the Sun, then the bend over, creating a
loop and then the field lines go into the surface of the Sun again. You are so good at looking at pictures and you never noticed that there are
loops and
arcades of loops on the Sun?
But you are playing a word game again, aren't you, MM? You only see "partial loops." Well that is exactly what I was talking about, and in real life these are called coronal loops.
And if you would look at pictures in different frequency bands, you would notice that we can see these loops to the footpoints, where bremsstrahlung is generating copious amounts of X-ray emission.
Where are the "footprints" in your opinion, and how much "shearing" must it take to heat plasma to millions of degrees?
You can observe the e.g. in the X-ray emission. The more shearing the more current that is just a basic physical law, and the shearing can either be the two foot points moving with respect to each other or the the foot point(s) being twisted "rolling up" the magnetic field in the loop.
These two statements are at odds. If the strong currents heat the plasma then there is a discharge process in the plasma.
What is it with you and discharges? The temperatures in the loops can easily be calculated by Ohmic heating in the loops, e.g. papers by
Bert van den Oord and
Battaglia & Benz and the various referenced in those papers. This all works without "discharges," but I get the idea that you mean something completely different with discharge than what mainstream says. Please explain in detail what you mean with discharge.
But the photosphere plasma is only 6 thousand Kelvin. It's not that "hot". Something is causing it to jump several OOMS in temperature. Here on Earth that happens in "discharges" in the Earth's atmosphere.
6000 deg is rather hot in my opinion, would not want to get caught in an oven at 6000 deg. But anyway, that is besides the point, whether you think something is hot or not. I was talking, I think, about the heated plasma in the loops which would emit radiation. But also a plasma at 6000 deg will emit radiation, because "that is what plasmas do."
But I explained already that the currents in the loop heat the plasma, basically through Ohmic heating and not through discharges and it is also not a "jump" process.
Why would it be ridiculous in your opinion to go with the one known force of nature that does this in the Earth's atmosphere?
Because the currents in the coronal loop are not discharge-like, they are constant, they
need to be constant and not just a lightning flash. Also the Birkeland currents in the Earth's magnetosphere are not "discharges" they are fully formed current circuits.
It's not originally that hot. Something has to heat the plasma, and that something is *ELECTRICITY*. It happens all the time here on Earth in electrical storms. Why would you need to look to any other form of energy if all you need to do is explain high temperature plasma? Electrical discharges and a do cause these sorts of emissions.
The same as above
How does it get hot then?
see above
"Reconnection" as it describe on WIKI requires the loops to actually "cross" in order for MR to occur. The problem for your theory is that the plasma is *ALREADY* over a million degrees in *BOTH LOOPS* even *BEFORE* they cross. How did that happen?
see above
You haven't personally *EXPLAINED* anything. Start with a single loops and explain how it reaches millions of degrees and sustains those temps.
Read up on the the theory, which was already being formed in the 70s by
van Tend & Kuperus and in the 80s
Kuperus & van Tend. There you will find all the basics about coronal loops and the currents and the heating and the reconnection/flare mechanism and and and
It's more than looking at pretty math formulas too. Observation and *EXPERIMENTATION* are the cornerstones of science. Math formulas are a dime a dozen. Birkeland's ideas work in a lab. You're idea do not and no terella in a vacuum ever spewed particles from the whole surface due to "magnetic reconnection".
Oh don't be silly, I am not an idea! I am a real person!
I guess you will discard all the experiments on reconnection in the lab, ah well, I guess because Birkeland did not do those experiments, we are not allowed to do them now, as Birkeland seems to be the pinnacle of modern science.
Maybe the terrella did not spew particles due to reconnection, because the set up of the terella experiment does not favour reconnection? Ever thought about that?
Yet that is exactly the mentality you are applying as it relates to Birkeland's solar theory. Anything you think I can't explain automatically seems to validate a gas model solar theory in your head even though none of you can explain those persistent features, or anything specific about either of those two images. Your theories do not work. They don't explain the observations. They don't explain the heliosiesmology data. They don't explain the RD images. They don't explain continuous solar wind acceleration for a whole sphere. They don't explain any of the key things that Birkeland's model not only "explained' but that he actually "simulated" in a lab with "electricity", something that is "natural" and occurs in nature, here on Earth , and in the solar atmosphere.
I doubt that I am doing that, I have great respect for Birkeland, and his deduction about corpuscules flying from the Sun to the Earth and that there is a relation between the appearance of aurora and changes in the magnetic needles that he and his assistants were observing. I am open for many things, but they have to be at least founded in some understanding of electromagnetism and I am sorry to say that your model of the Sun and the solar wind have so many things that are inconceivable in real life that I cannot accept your theory. Naturally, you could try to show me how the electrons from the Sun pull along the ions, regardless of the mass difference between the two and the opposing electric field working on the ions, but after repeated requests all I get is "read Birkeland". But is should be rather simple, so please write it down for us, is it so difficult to defend you model with some quality?
