Why are the sun spots so much darker than the rest of the surface of the sun?

The sunspots are darker because the surrounding area is much hotter. All we know about the Sun's interior is derived from pure theory alone. A few renegades have proposed solid or denser interiors but it will probably be a long time before we are dropping probes into the Sun to find out.

Sunspots are dark in that they are not points from which visible light is emitted. However, light in other wavelengths is being emitted from these cooler areas. The magnetic field convergence just cools down an area for awhile. Concerning the interior of the sun, matter in the form dense gases being pushed together due to gravity could very well be in a state of matter not fully explored yet.
I propose that when these gases inhabit the high pressure/temperature environment their behavior is more like a fluid than plasmas are usually described as. Perhaps emission of visible light is a product of vicinity. Just as when a pot of water boils, the water at the bottom of the pot must wait for the water at the top to evaporate. When water gets to 100 deg C, it doesn't just poof disappear. As the matter/energy convects to the surface it then is quickle freed to the vastly different environment of space (i.e. barely any temp and pressure) This escape allows the full EM spectrum to be emitted. In the case of dark sunspots, the magnetism opens windows into the interior without allowing access of that matter to the surface in MHO.

Mark, how is that any different then what I was saying in the original post that you disagreed with?

The definition of dark matter is matter that is never emits light. It is supposedly at the center of galaxies supplying the extra mass needed to generate the supposed gravitational force necessary to hold galaxies together in the BB. In the sun picture, it is dark because of 1.) low temperaturea and 2.) a reaction potential suppresed by magnetism.
That is the difference.

What if there were an outer, weaker(maybe plasma), layer or shell around the dark matter? One that could emit light and is continually being feed energy from the dark matter core. What do you think?
