The Message in the Rocks

Friday, February 17 · 60 min

Develops the theory that four and a half thousand million years ago the earth was formed thanks to the explosion of a huge star which provided the rocks, the minerals and the radioactivity from which life developed. These theories are based partly on analysis of a meteorite which dropped near a village in Mexico at the beginning of the seventies.
