[@HotPinkst17]

My favorite mystery of the Sun is how the photosphere can be so much cooler than the layers above and below it. My idea to explain this is that the combination of high gravity and especially high magnetic field density constrains the motion of atoms with more force than the temperature driven kinetic energy of the atoms. The amount of electrons falling back towards a ground state is likely higher in this region as well, creating something analogous to evaporative cooling right at the top of the convective cycle where energy escapes at the speed of light and material at the speed of the solar wind. Magnetically constrained motion would electromagnetically overpower the motion phenomenon we observe as temperature and the most energetic elements are rapidly leaving the photosphere is a tidy hypothesis. How can we test this now with current equipment?

While watching this an odd thought struck me. We are pouring masses of research into making a practical fusion reactor, but we already have one in our sky. All our energy (except, ironically, nuclear) has ultimately come from that natural fusion reactor pouring its energy into our biosystem. We even use its fusion power directly when we deploy solar panels. Surely it must be worth putting major effort into developing ways to use our already existing fusion reactor more effectively?

[@BeErnyify]

there is a lot of research put into making more energy and resource efficient solar cells, though having the fusion here on earth would help us greatly in understanding, how it works. Also, why not?

[@rockbore]

14:58 "The Apollo astronauts reported having these flashing lights in their eyes, even when there eyes were closed." Almost correct. The fact is we didn't hear these reports from any Apollo crew. They came from the shuttle crew who repaired the HST lense fix in 1992. That detail may turn out to be significant, or, for you it may not. But nice to get it right, surely. Apollo astronaut were asked about this in interview quite recently. The answer was not reassuring for those of us who still want to believe in the veracity of the moonlandings.

[@w0033944]

I can't work-out the relevance of comparing that UV spectrum to shutters across a window, which don't separate light of different wavelengths. I suppose, i blocking strips of light from entering the room they will cast a striped pattern of a wall behind, but it really isn't the same thing, or am I just being slow on the uptake?

[@WiseandVegan]

Search for "diffraction grating", and you will see what she meant. It's simply equivalent to a prism, but unlike prism it does not absorb some light, and much lighter so cheaper to put into orbit.

[@w0033944]

Thanks for the explanation. I see that she's using equipment which has the effect of a diffraction grating, what I don't understand is the direct comparison to shutters which don't act in the same way.

[@WiseandVegan]

I think she meant window shutters. You know, many little slits separated with equal distance. Check this out, it will make sense: socratic.org/questions/why-is-diffraction-grating-more-accurate-than-double-slits-to-measure-the-wavele

[@w0033944]

Thanks, but I do understand what a diffraction grating is. I'm trying to explain that, because window shutters don't separate the spectrum, I don't think the comparison is valid.

[@WiseandVegan]

They separate the light in microwave range. You just don't see it. She was just giving an example for kids to visualize.

[@jayfarina4890]

Hurricanes are atmospheric vortices on earth and sunspots, being vortices on the sun, could technically be considered solar hurricanes. Solar tornado is closely analogous, especially if earthly tornados ran from surface through lithosphere. You have the best job on the planet, bar none.

[@robert8124]

The computer generated images of the theorized Flux rope, could be spot on. The rope turning on itself, causing a electrical short. There by causing a explosion. Like a transformer or a wire carrying high electrical charge. looping/bending around and touch at wires midpoint shorting out.

Isn't the 'flux rope' just plasma that has acquired enough energy to break loose the constraints of the magnetic fields holding it? Did not a recent observation show that the fields influence the sunspots FROM ABOVE rather than from below (below the sun's 'surface')? That was presented at Suspicious Observers last week iirc.

[@gyro5d]

Mediated to the center of stars are protons, made of positrons, from the Inertial plane/Counterspace. The first to leave the Inertial plane is Dielectric energy. This is when the Universe and Time started. Inflation. Then, Dielectric Voidence Field/Magnetism was created from the Dielectric energy. The transverse waves that EM waves perturbate on/in Tesla nodes. The Grand Expand. Magnetism gives Magnitude to the Universe. Gravity is Dielectric Voidence Field/Magnetism returning to Dielectric energy. No transverse waves anymore, just Dielectric energy. So, no light, in a Blackhole/Counterspacial Sink. Dielectric energy returns to the Inertial plane. The Inertial plane, "Condensate of Universe". e->~

Is the speed of light the same at fifteen millions degrees ? Can the Sun electrons speed increase ?

[@paavobergmann4920]

The speed of light is the speed of causality, and it is a fixed limit throughout the universe. It´s not so much a speed as it is a speed limit. Light can reach this limit, because it has no mass. Electrons have mass, so they can´t even reach it. No, temperature does increase the speed of particles, but it does not increase the absolute speed limit.

[@paublusamericanus292]

I really like lucie. she is a tremendous scientist. I felt, the explosion was driven on the surface, by a fusion when the magnetic rope kinked. not true. this has to do with the generation of distortions on earth of silicon 32 temporal links. more is going on, in the kink, than can be described easily. it is altering, space/time itself, and causing this electrical pulse, which is generating, a relativistic temporal flow, at the split instant of congealing, into the burst. it is space/time alteration in the james clerk maxwell vacuum that is causing all this energy from the solar dynamo spinning angular momentum, into this tiny bit of space/time alteration, that is spectacular, and lifts a mountain into space. In fact if I am correct, ligo can detect this flux moment. But will be not a wave, but a singlet. a pulse, thus lifting the mountain, and should be visible, if I am correct, as a single transient, down or up, then not vibrating back to norm, but an instantaneous leveling, but each detector, seeing the small flux, at the same time, depending on light speed to each unit.
