Hello.
大家好
My name is Stephen Hawking
我是斯蒂芬·霍金
physicist, cosmologist

And something of a dreamer.
还可以说是一个梦想者
Although I can not move and I have to speak through a computer.
尽管我行动不便，说话要借助电脑
In my mind, I am free.
但在精神世界中，我是自由的

And if we met them,
还有如果他们真的现身
what would it mean for humankind?

Check it out.
一起去探索吧

Wherever I go in the world,
无论我到哪里
people ask me, do aliens exist
人们总喜欢问，外星人真的存在吗
it's a good question,
这问题问得好
because it cuts to the heart of how we see our place in the universe.
因为它直接关系到我们在宇宙中的地位
Are we alone on our small, round, blue ball?
浩渺宇宙，地球是唯一存在生物的星球吗
I think probably not, because of one fact.
我想不会，这基于一个重要的事实
The universe is big... really big.
宇宙浩瀚，无边无垠
Our planet is just one of eight in orbit around our sun
我们的星球不过是太阳系八大行星之一
Which itself is hardly special,
作为两千亿颗星星中的一枚
being one of about 200 billion stars in a vast spare
地球实在说不上特别
Our galaxy, the milky way.
我们所在的星系，银河系
It's so big, some days I find it hard to comprehend.
它是如此庞大，以至于我时常觉得它深不可测
But even the milky way

is just a tiny drop in a cosmic ocean
也不过是苍茫宇宙中的一粟
just one of 100 billion galaxies formed into

an enormous web stretching away in all directions.
向四面八方张开的巨网中的一点
At this scale, each point of light is an entire galaxy,
在这一画面中，每个亮点都是一个星系
which not only puts our little world in perspective
这不仅让我们清楚地看到自己的渺小
but also makes it difficult to believe we really are alone.
更让我们难以相信自己真的是唯一的存在
So to my mathematical brain, the numbers alone
从数学逻辑看来，单是如此巨大的数字
make thinking about aliens perfectly rational.
就足以使外星生物的存在不是无稽之谈
The real challenge is to try and work out
真正的难题在于，如何获悉
what aliens might actually be like, living on some far-off world.
住在遥远外太空的生物，究竟长什么样子
the possibilities are infinite and infinitely intriguing.
这有无限可能，也引人无限遐想

视频及简介

《与霍金一起了解宇宙》纪录片耗时3年多制作，期间霍金曾多次坚持对剧本作大幅修改。霍金指出外星生物在消耗尽自己星球上的资源后便会乘坐大型飞船到他们能够到达的星球掠夺资源，并将那里开拓成为他们的殖民地；如果有外星生物到访地球，那将会像当年意大利航海家哥伦布登陆美洲大陆一样，最后给人类带来毁灭性的灾难。
