Article concerning the composition of the Sun.
Any addition of any theoretical Iron to the Sun serves only to make it MORE massive not less. As I said, the Sun would have to be made out of ‘magic’ to be less dense than hydrogen and helium.
Hence my point about science constantly changing, neccesitating a change in theory to keep up with constantly changing data. Thus, I am slow to place my confidence, and argue for acceptance of, theory that will change tomorrow with a better satelite, instrument or computer. We are explorers, and curious by nature, and demand explanation for what we see. Our premise about origins, however, determines how we will hypothesize explainations of our observations. As Einstein once said, "It is theory that determines what can be observed."
