I have NO idea what's beneath the surface. I can only tell you it has a solid surface. The only thing I can note from SERTS data is that during "active" phases the sun emits more sulfur and nickel.

Probably because you destroyed your retina. Seriously, this is basic astronomy. You can't look at the sun with the naked eye for more than an instant without damaging the eye and you certainly can't identify sunspots that way. You have to use a filter or other method to reduce the intensity of the light. Sunspots only appear dark through a filter because they are relatively darker than the rest of the surface. From:

It was your beloved Galileo, the father of the gas model, who went blind staring at the sun, not me. I'm not foolish enough to stare directly at the sun. I use a computer monitor to study the sun. Do you always make such rash and irrational assumptions about people you don't even know?

A sunspot is a region on the Sun's surface (photosphere) that is marked by a lower temperature than its surroundings, and intense magnetic activity. Although they are blindingly bright, at temperatures of roughly 5000 K, the contrast with the surrounding material at some 6000 K leaves them clearly visible as dark spots. Interestingly, if they were isolated from the surrounding photosphere they would be brighter than an electric arc.

What makes it go black in the center of the sunspot as it relates to visible light? Why would a 1000K difference result in a completely BLACK (visible light) sunspot? What's "radiating" visible light? Specifically what molecules are involved? What makes it reform a shiny layer again? Why do we see "sides" along the penumbral filaments?

Different types of photons? What are you talking about?
|
The wavelength of the photon will determine whether we can "see" it. Why can't we SEE a sunspot but see the whole shiny surface?

And, of course, the visible light does not disapear in a sunspot.

Have you ever looked at sunspot?

Uh, right. A solid surface and different photons. Oh, and black hole sunspots - which clearly doesn't match reality. Much simpler.
|
What are you talking about? Photons come in ALL wavelengths. Who said anything about a black hole? I said visible light is not emitting from the center of the sunspot. I asked you why that might be. Rather than addressing it, you created a set of strawman arguments that have NOTHING AT ALL to do with anything I've said.

And as said previously, the sun does have these elements, but the percentages are different because it didn't form the same way.
|
How do you *KNOW* it didn't form the same way?

Anyway, I would suggest you read some basic astronomy books. It is clear that you have some fundamental misunderstandings on this subject.

Pure argument by ridicule utterly devoid of scientific merit. Please read about photons and wavelenghts of photons before you stick your foot in your mouth again. It's clear you haven't a clue what you are talking about.
