Science goes from question to question; big questions, and little, tentative answers. The questions as they age grow ever broader, the answers are seen to be more limited.

I would rather have questions that can't be answered than answers that can't be questioned.

People forget that when you're 16, you're probably more serious than you'll ever be again. You think seriously about the big questions.

I've never worried about life's big questions.

There are still a lot of big questions about what they would have eaten.

'Why are we here?' 'What is our purpose? 'Is there an afterlife?' 'Is there a God?' 'Is it all about science?' Those are big questions, and usually, TV is a little scared to go there.
