Let's see. I didn't claim Earth has a hydrogen core in this thread. Some people can sure jump to conclusions or should I say, make assumptions. All I asked was, "Does anyone know of a more plausible theory of how Earth developed a core containing such a enormous excess of iron?"

Eaarth's formation in an iron-rich ring of dust and gases is a new one for me. How very convenient. How equally unlikely, but a good attempt and perhaps even possible. At least someone may not be committed to dogmatic assumptions.

So many seem to think Earth is a totally unique situation. I, for one, perhaps the only one it seems, thinks Earth was formed by a process that is no different than that of many others, if not all others. Which is why I find the Grand Bombardment theory so stupid, when the gravitational attraction of the Sun and Jupiter is considered. Hard to believe some so-called scientists would even consider 'swarms' of iron-rich micro-planets attacking only Earth in a short (?) period of time and making it molten, while the swarms apparently ignored the Sun and Jupiter.

Apparently, the usual assumptions made in amother thread are still being vented, even though I stated I don't know if Earth has a hydrogen core and only asked where did all the iron come from. Puzzling to say the least, considering I was previously assured the basis for this forum is 'social' discussion.

Please answer the question, if you can, and save the condemnations for another thread, in which I can't find the time to participate due to my time consuming care-giver duties during the day.

Apparently, the fact that no one really knows for sure seems to have hit a nerve. At least I know I don't know everything. I only wanted to know if there were any other theories about Earth being formed with an enormous excess of iron which had some logical sense about them.

Well? Where did all the iron come from? Why does the Sun and Jupiter have so little? Simple questions from a simple old car mechanic.

Anyone remember the story of the Emperor's new clothes?
