The Surface of the Sun : Michael Mozina's theory of the solid surface of the Sun.
From the website : "The sun's photosphere is often mistakenly referred to as the surface of the sun. In reality however, the sun's photosphere is only a "liquid-like" plasma layer made of neon that covers the actual surface of the sun. That visible layer we see with our eyes is composed of penumbral filaments that are several hundred kilometers deep. This visible neon plasma layer that we call the photosphere, and a thicker, more dense atmospheric layer composed of silicon plasma, entirely covers the actual rocky, calcium ferrite surface layer of the sun. The visible photosphere covers the actual surface of the sun, much as the earth's oceans cover most of the surface of the earth. In this case the sun's photosphere is very bright and we cannot see the darker, more rigid surface features below the photosphere without the aid of satellite technology."
