That is a cosmic perspective, that's correct. And in tandem with that, you will never find people who truly grasp the cosmic perspective such as the entire community of astrophysicists leading nations into battle. No, that doesn't happen. When you have a cosmic perspective, there's this little speck called Earth and you say you're going to do what? You're on this side of a line in the sand and you want to kill people for what?

So not enough people in this world, I think, carry a cosmic perspective with them. It could be life-changing.

I remain unconvinced that anything other than rapid decomposition is the fate of my body and mind after death.

For the film to 'earn' the right to be criticized on a scientific level is a high compliment indeed.

We're an elective democracy where science and technology will define where the economically strong countries in the world will be. And science and technological literacy is important for security, as well.

Some molecules - ammonia, carbon dioxide, water - show up everywhere in the universe, whether life is present or not. But others pop up especially in the presence of life itself. Among the biomarkers in Earth's atmosphere are ozone-destroying chlorofluorocarbons from aerosol sprays, vapor from mineral solvents, escaped coolants from refrigerators and air conditioners, and smog from the burning of fossil fuels. No other way to read that list: sure signs of the absence of intelligence.

I think science has a better story to tell than anyone else has been able to tell and that's because it's based on the rigorous winnowing that science and scientists are always doing in order to find out what's really happening. I think it's really good to encourage generally our ability to tell stories and that's a great skill that we come by naturally, so I'm excited about that.
