"Iron cannot in a normal state, be in gaseous form or any other form but a solid.

"

Huh? Iron is fairly easily melted, so it is not always in a solid. Anyone who does welding melts iron frequently. Use a cutting torch? Then you're burning iron in oxygen. That's where all those sparks come from. At a high enough temperature, iron vaporises, as well.

I said normal state.

High temps are required to melt. Normal state is what it is. The normal space conditions. Usually in the very cold category. Iron would be a solid and likely a dust. It cannot be compressed as a gas can and it is not known to react with anything but oxygen.

That is what I meant. Great planetary building material but not likely to start a fusion or fission reaction.

Kind of a nutty theory IMO. We know a great deal about the sun. not enough mind you, but a great deal of information has been gathered, to include much data about composition. Not theory, but data. This article flies in the face of everything we know.
