Why call it a catastrophe? What's catastrophic about this occurrence? 204.52.215.107 06:46, 13 September 2007 (UTC)
the denser iron, held in the outer layers, sank
what was actually holding it in the outer layers? Luca Lesinigo ( talk) 19:56, 19 February 2008 (UTC)

I've always assumed "catastrophe" was meant in the mathematical sense, as in the "catastrophe theory" page on Wikipedia, basically a sudden dramatic change in a system. But I could be talking complete bollocks. 217.37.50.66 ( talk) 15:30, 16 July 2010 (UTC)
The article says the Iron Catastrophe occurred 500 Million Years after the formation of the Earth. I was rather confused by this at first, and went looking for more info, because everyone seems to agree that the Moon was formed after the Iron Catastrophe, yet the Moon creation date is always listed much earlier, around 30-50 Million Years into the Earth's history. [1] This was the first source I could find that reconciled the two satisfactorily. I guess I am hesitant to edit until someone who should know more about this than me comes along. —Preceding unsigned comment added by 97.84.147.142 ( talk) 15:13, 26 August 2009 (UTC)
Surely people are wondering why the iron (being lighter than gold, copper, silver, etc.) would comprise the center when gold, silver, copper, etc. are heavier and have a lower melting point? It seems like the iron catastrophe was invented by 1800's scientists. Wavyinfinity ( talk) 23:53, 5 November 2014 (UTC)
In the present version of the article: "this event was necessary for life to emerge and evolve on Earth: without it, Earth's atmosphere would have been, as on Mars, stripped away long before the present epoch." What does this mean? -- Alexey Muranov ( talk) 10:57, 14 May 2015 (UTC)
