Then so be it. You can't however determine density until you understand thicknesses of various layers.
|
The average density has been determined. Are you saying there is a thin solid layer over a gaseous interior?

Huh? They are VERY dark to the naked eye.

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:

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.

Different types of photons? What are you talking about? And, of course, the visible light does not disapear in a sunspot.

Even if it were "cooler", it should not be SO cold that NOTHING shines from that spot, but shines right around the edges like that.
My explanation was MUCH simpler, and I'll just stick to the Occum's razor concept when we have competing idea.
|
Uh, right. A solid surface and different photons. Oh, and black hole sunspots - which clearly doesn't match reality. Much simpler.

I still haven't heard a logical explantation as to why the earth and venus and mars are full of heavy materials, but somehow the sun is imunne. That doesn't make much sense of you ask me.
|
And as said previously, the sun does have these elements, but the percentages are different because 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.
