well, we we re working with one of the greatest living scientists, one of the best scientific brains in the world. and i m not a scientist. my job on this series for discovery channel was to bring the views, the vision, the imagination of this great scientist to a mass audience. these are the words of professor hawking. i don t have the scientific credentials to secondguess professor hawking. i m prepared to believe him because he is such a great scientist. and what we said about aliens in that program was very much what stephen hawking wanted to say. for years he had been lecturing about about lots of things, including the possibilities of alien life. what we were able to do for the first time using the wonders of computer graphics was to visualize with professor hawking hypothetically what they might
say you can t say one way or the other. you can think maybe caution would be a good idea. larry: stephen theorizes the negative aspect, does he not, john? he rightly thinks we should be cautious, and i m not going to secondguess professor hawking. but that is what is so intriguing, isn t it, about this whole subject? could there be life out there? if so, is that just some sort of green gloop or is it something that is a real menacing threat? that s what we don t know. many better scientific minds than mine are obsessed with looking. i think you ve got guests later who will tell us a lot more about that. but it is just totally intriguing. it s been the subject of literature. it s been the subject of movies. and i think the one of most intriguing questions of all, which is why it s one of the questions stephen hawking himself wanted to deal with in this series.
