Stephen Petranek: At first, it all seemed a little fantastical to me, but after challenging a lot of these ideas, I began to take a lot of them seriously. And then September 11 happened, and I thought, ah, God, I can't go to the TED conference and talk about how the world is going to end.
Mulanya semua terlihat agak tidak masuk akal bagi saya, namun setelah menantang banyak gagasan ini, saya mulai menganggapnya serius. Kemudian terjadi peristiwa 11 September, dan saya pikir, ya Tuhan, saya tidak bisa pergi ke konferensi TED dan berbicara tentang bagaimana dunia akan berakhir.
