I'm surprised they neglected a fifth theory- the moon impacted the Earth in an almost tangential, glancing blow.
Liquefied rock from the impact event spread over both planetoids, making the core of the moon completely different from its new skin, not unlike dipping chocolate in candy or vice versa.
The impact also allowed for the capture of the moon but at some large distance.
Just a theory, yet it explains a lot about Earth geology that the other theories leave unexplained.
- eponeponepon 9y agoSeems to me that it's only the minutiae of the hypothesis that are in question - unless I've misread the article, the overarching theory that an impact of some kind caused the moon's formation is still the working assumption, no?
- jdmichal 9y agoI've never heard a theory that the moon itself impacted the Earth. There has been discussion of the idea of a fast glancing blow by Theia, which is omitted: http://www.bbc.com/news/science-environment-19011013 http://www.bbc.com/news/science-environment-19011013
