Moon: New formation theory 'involves giant impact' - BBC News

Debarjun Saha | 03:19 |

A conference has been called at the Royal Society to try and regain some sort of consensus on how the moon was formed.

Since the first global conference in 1984, improvements in scientific analysis of samples from the moon, other planets and earth have disproved the theory that the moon was formed from a major collision between Earth and another planet named Thea.

Professor Alex Halliday, head of the science division at Oxford explained that one of the things likely to be agreed upon is that the moon is quite a bit younger than once thought.

He said that because of the chemical make-up of the moon, its formation had to have come from "some sort of giant impact".

First broadcast on BBC Radio 4's Today programme on Monday 23 September 2013.
