The moon has confounded scientists for many years. It does not obey the known rules of astrophysics and there is no theory of its origin that explains the known facts – in fact it should not really be there. When researching the ancient system of geometry and measurement used in the Stone Age that they discovered in their previous book, Civilization One, the authors discovered to their great surprise that the system also works perfectly on the Moon! On further investigation, they found a consistent sequence of beautiful integer numbers when looking at every major aspect of the Moon – no pattern emerges for any other planet or moon in the solar system.
