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?

You left out the statement I was commenting on, so I added it back in. This was a small joke. The word "Seriously" was a hint. The point being that it is very dangerous to look at the sun with the naked eye as you first suggested. This is not a good way to look for sunspots. I'm glad to see you conceded the point.

In order: It doesn't. It isn't. The same gas as everywhere else on the sun. See the list
in this post. The sunspot/magnetic storm collapses (see sunspot references for details). The structure of the sunspot is based on the interaction of the solar magnetic field.

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? |
While the peak emission wavelength changes with the lower temperature, it is well within the visual range. As to your question: Go out on a moonless night. How many stars do you see? Now do the same on a moonlit night. How many stars? Now go out in daylight. Repeat the process. Did the stars go out or is it simply that you can't see them?

Have you ever looked at sunspot? |
Yes, with appropriate equipment. However, simple visual examination isn't a useful method for determining the amount of light coming from a sunspot so I don't see your point.

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 was referring to the following paragraph. I've taken the liberty of emphasizing points of interest:

They have other types of photons flowing through them of course, but in that region, the visible light simply disapears, and we can see highly defined "sides" to this "layer" of "penumbral filaments". What the deal with the BLACK hole in just these specific locations, and along the sides of the penumbral filament layer?
|
Does that clear things up? Incidentally, wavelength doesn't a change photon's "type." A photon is still a photon.

I answered you directly. To repeat: You're incorrect. Visible light is emitted at the center of the sunspot. This has been very well established and carefully measured. See my previous posts and the links I provided for details.

How do you *KNOW* it didn't form the same way? |
Numerous reasons - relative availability of elements in space, examination of the sun and stars, examination of planets, examination of stellar nurseries, models of the effect of different masses on formation, models of the effect of a star on planetary formation, etc. And there is the simple observational fact that the sun CANNOT have the same relative percentage of elements as the earth.

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. |
Some might consider that ironic. From your statements and questions about sunspots (among other things) it seemed reasonable to conclude that you are not familiar with a number of facets of mainstream astronomy. If you want your alternative hypothesis to be taken seriously, you should learn something about what you are arguing against. Your insistence that sunspots are "black" is a perfect example of the problem.
