“If we had known everything in this universe, we would have had to find another universe to feed our curiosity, because what keeps alive man is the curiosity!”

“We ought to view ourselves with the same curiosity and openness with which we study a tree, the sky or a thought, because we too are linked to the entire universe.”

“Curiosity keeps me alive.”

“If the spirit of wonder & curiosity stays alive in us, then surely we will always have new questions, and always expand our creativity in response?”

“So long as the universe had a beginning, we could suppose it had a creator. But if the universe is really completely self-contained, having no boundary or edge, it would have neither beginning nor end: it would simply be. What place, then, for a creator?”

“How many people are we going to lose before the universe decides we've had enough?" Carly asked me. I didn't answer, but if I had known what was coming I would have said, "All of them.”
