New theory on the formation of the Moon

Article from Nature

A new theory has come out claiming that the origin for the Moon was a multiple-little-impact against the old theory of an only one giant-impact.

The formation of the Moon would be the result of various collisions: A big body would collide with a young Earth, emiting material which would have formed a disk around the Earth. Afterwards, it would have condensed to a celestial body. This process would have happened about twenty times, generating twenty celestial bodies which finally would have unified resulting in the current Moon.


This theory could be proven, according to Jose Manuel Carrasco, interviewed by TV3, by testing different layers' depths, whose composition should be slightly different. In order to prove this theory, another space mission should be launched to the Moon. Anyone on board?
