I'll take a stab at some serious thoughts here. (adjusts glasses, ahem)

While I'll grant to Dr. Manuel there is a "small" ball of Iron at/near the core of the Sun, I find it highly doubtful that it is a major component.

If the Sun were infact mostly iron I think it would show up in the mass-to-volume (density) ratio. Per my "baby astronomy" class in college, the density of the Sun is consistant with a compsition of 99.XXXX% hydrogen.

Does anybody know if it is possible to calculate if it is possible for the Sun to look/behave as it does, having a mass that is (arbitrarily selected) 51% Iron? I select 51% because it is the minimum whole percentage that permits the Sun to be "mostly iron" as Manuel claims.

I have no scientific calculations to support this but my sense of the "Force" is that the answer is no. An iron ball with 51% the mass of the Sun would have a huge surface gravity and would cause the Hydrogen layers to fuse faster and, therefore, release more energy than is currently observed.

Anybody have any better thoughts?
