Is our current theory of Earth’s formation mistaken?


Image result From ScienceDaily:

New geochemical research indicates that existing theories of the formation of the Earth may be mistaken. The results of experiments to show how zinc (Zn) relates to sulphur (S) under the conditions present at the time of the formation of the Earth more than 4 billion years ago, indicate that there is a substantial quantity of Zn in the Earth’s core, whereas previously there had been thought to be none. This implies that the building blocks of the Earth must be different to what has been supposed. The work is presented at the Goldschmidt geochemistry conference in Paris. More.

Paper presumably to follow. One of the nice things about science, when it actually works, is that it isn’t full of addled mediocrities pounding lecterns to splinters demanding that we Accept their truths or else they will Fix us.
