... Тhis new concept touches our simple lives, yet for those intrigued by the natural sciences, especially experts deeply engaged in the 'eternal' questions of general geology and astronomy, it is all the more fascinating. The problems to be faced by any theory for the formation of the Solar System . Any theory has to account for certain rather tricky facts about the Solar System. These are in addition to the obvious facts that the Sun is at the centre with the planets in orbit around it. ...
