Please, see my reply to Edge's post relating to the calculation of advanced civilizations. http://www.youtube.com/watch?v=dilKJ6uLCc8&feature=related Also, a scientist from the Vatican's Observatory, who happens to be a Jesuit priest, presented his ideas about the universe a film clip that was posted here several weeks ago. Regarding the evolution of life in the universe, he quipped that "God does not play dice. But He loaded it." (so that life may evolve without violating the rules of physics or natural law.) > > > > http://www.youtube.com/watch?v=h76JFOuCpXI&NR=1 > > >
