On a typical day at school,

在學校的日子

endless hours are spent

我們花了無數時間

learning the answers to questions.

來學習許多問題的答案

But right now, we'll do the opposite.

但現在，我們做的恰好相反

We're going to focus on questions where you can't learn the answers,

我們要看看那些你不能學到答案的問題

because they're unknown.

因為它們仍是未知的

I used to puzzle about a lot of things as a boy.

當我還是個小孩子，我經常思索很多東西

For example, what would it feel like

例如

to be a dog?

如果我是一隻狗，那是什麼感覺？

Do fish feel pain? How about insects?

魚會感覺到痛嗎？ 昆蟲呢？

Was the Big Bang just an accident?

宇宙大爆炸是個意外嗎？

And is there a God?

上帝存在嗎？

And if so, how are we so sure that it's a He and not a She?

如果祂存在，我們怎麼確定衪是男是女？

Why do so may innocent people and animals suffer terrible things?

為什麼有這麼多無辜的人們、動物受苦？

Is there really a plan for my life?

我的人生是否早已有了安排？

Is the future yet to be written,

未來是等著被寫下？

or is it already written

還是它早已寫定，只是我們無法窺見？

and we just can't see it? But then, do I have free will?

那麼，我有自由意志嗎？

Who am I, anyway? Am I just a biological machine?

我是誰，或者，我只是個生物機器？

But then, why am I conscious?

那麼，為什麼我有意識？

What is consciousness? Will robots become conscious one day?

什麼是意識？機器人會有一天變的有意識嗎？

I mean, I kind of assumed

我想，有一天

that some day I would be told the answers to all these questions.

有人會告訴我這些問題的答案

I mean, someone must know, right?

我的意思是，總有人知道吧？

Huh. Guess what? No one knows.

猜猜怎麼著？任何人都不知道

Most of those questions puzzle me more now than ever.

這些問題大多仍使我困惑

But diving into them is exciting

但沉浸在它們之中是很有意思的

because it takes you to the edge of knowledge,

因為它帶領你到知識的邊際

and you never know what you'll find there.

你永遠都不知道你會在那裡發現什麼

So, two questions to kick off this series,

那麼，我們用兩個問題來揭開序幕

questions that no one on Earth knows the answer to ...

兩個地球上沒有人知道答案的問題...

Text: How many universes are there?

到底有多少個宇宙？

Why can't we see evidence of alien life?
