Folks, I've moved this thread from the ATM section, to the Q&A section.

Please limit your contributions, from now on, here, to a discussion of why, in big bang cosmology models, there was no Fe at the time of the CMBR (the 'surface of last scattering').

Specifically, MT, if you wish to discuss Michael's ideas concerning a 'big slam', please start a thread in the ATM section on that topic (the two current threads are about his 'sun has a solid iron/ferrite surface' and 'mass cannot be accurately determined by GR or Newtonian gravity' ideas.

As it's not yet 1 October, this is not a warning.
