After Chris Jordan, there is a special video conference call from Stephen Hawking, who is the Lucasian Professor of Mathematics at Cambridge University.
Brilliant man. Hawking also believes in determinism, which I wrote about in an old post here, "Is Man Determined or Free?" Excerpt:
Back to Hawking, he continued by stating his fear for the long-term survival of our species, “My only fear is this. The terror that stalks my mind is that we have arrived on the scene because of evolution. Because of naturalistic selection, and natural selection assumes natural rejection, which means we have arrived here because of our aggression. And my hope is that somehow we can keep from eating each other up for another 100 years. At that point science would have devised a scheme to take all of us into different planets of the universe and no one atrocity would destroy all of us at the same time.” (full post)
