旅行者号♥航♥天♥器的母星
Voyager spacecraft in our galaxy.
他们也能知道
They could also tell
这架航♥天♥器是多久之前发射的
how long ago the spacecraft was launched.
这很重要因为旅行者号♥上搭载的唱片
And that's important because the Voyager record
预计有效寿命为十亿年
has a projected shelf life of 1,000 million years.
暂时假装我们是外星考古学家
Become an extraterrestrial archaeologist for a few moments.
一件智慧生物造物从星际之海打捞上来
An artifact has been fished out of the interstellar ocean.
它是由生活在
It was made by beings
大约十亿年前的生物制♥造♥的
that lived about a billion years ago.
你会如何去了解他们和他们生活的世界
What would you make of them and their world?
他们为我们送上音乐和
They've sent us their music
五十九种人类语言的问候

这一切都将能保存长达十亿年
All of that will live for a billion years.
《地球之声》
献给所有世界的各个时代的音乐创作者们
十亿年有多久呢
How long is a billion years?
如果你能把从大爆♥炸♥
If you can press all the time since the Big Bang,
即宇宙诞生之时起到现在所经历的时间
the explosive birth of the universe,
压缩成地球上的一年
into a single Earth year,
十亿年大约是其中的一个月
a billion years is about one month of that year.
十亿年前的地球上是什么样的呢
What was happening on Earth a billion years ago?
当时地球上绝大部分陆地聚集为一块
Most of Earth's land was amassed into a supercontinent
被称为罗迪尼亚的超级大♥陆♥
called Rodinia.
那是一片荒凉的沙漠
It was a barren desert--
没有动物没有植物
no animals, no plants.
十亿年前地球大气中还没有
A billion years ago, there wasn't enough oxygen
足够的氧气来形成臭氧层
in our atmosphere to form an ozone layer,
没有臭氧层紫外辐射
and without it, ultraviolet radiation
使生命无法在陆地上生存

单细胞生物统治着海洋
Single-celled organisms dominated the oceans,
有一些生存于被称为"微生物席"的菌落
but some existed in colonies called "microbial mats,"
第一种多细胞生物即将演化形成
and the first multicellular organisms would soon evolve.
那么十亿年之后
And a billion years from now,
地球将会是什么样的呢...
what will Earth be like...
那将是在我们的城市埃及金字塔和
long after our cities, the Egyptian pyramids,
落基山脉都被侵蚀为尘埃之后的悠远未来
the Rocky Mountains have all been eroded to dust?
关于这一遥遥无期的未来
There are few things we can say with confidence
我们能确定的东西很少
about such a far distant time.
我们唯一能肯定的是
The only thing we can say for sure
我们熟知的地球所经历的变化
is that Earth as we know it will be so changed
将使我们难以再将其认出为曾经的家园
that we would scarcely recognize it as home.
然而即使经过十亿年
But even a thousand million years from now,
一些关于人类本质的东西
something of who we were and the music that we made
和我们在那个悠远的春天创作的音乐
in that long-ago Spring...
都将幸存下来
will live on.
在那遥远的未来
In that distant future,
我们的太阳将已经完成
our Sun will have completed

卡尔·萨根曾是旅行者任务成像小组的成员
Carl Sagan was a member of Voyager's imaging team,

上一代人之前
A generation before,
最后一次阿波罗登月飞行中的一名宇航员
an astronaut on the last Apollo flight to the moon
为整个地球拍了一张照片
had taken a picture of the whole Earth--
整个星球作为一个没有疆界的世界
the planet as a world without borders.
它成为了一种新思潮的标志
It became an icon of a new consciousness.
卡尔意识到这一进程的下一步
Carl realized the next step in this process.
他说服了美国宇航局在旅行者一号♥
He convinced NASA to turn the Voyager 1 camera
飞过海王星时
back towards Earth
把它的摄像头向后转向地球
when the spacecraft went beyond Neptune
最后再看一眼家的方向那被他称作
for one last look homeward at what he called...
"暗淡蓝点"的地球
the Pale Blue Dot.
就在这儿
That's here.
那就是家园
That's home.

那颗悬浮在...
on a mote of dust
一缕阳光之中的微尘之上
suspended... in a sunbeam.
在宇宙宏大的竞技场上
The Earth is a very small stage
地球只是一个很小的舞台
in a vast, cosmic arena.
想一想血流成河
Think of the rivers of blood
只为那些帝王将相的
spilled by all those generals and emperors
荣耀和胜利
so that in glory and triumph
让他们得以短暂地主宰
they could become the momentary masters
一个点上的
of a fraction...
一小点
of a dot.
想一想这个像素点上一个的角落
Think of the endless cruelties visited
那里的住民曾把无尽的残酷
by the inhabitants of one corner of this pixel
施加于另一个角落里与其没有多少差别的
on the scarcely distinguishable inhabitants
其他同类
of some other corner.
他们的误会竟如此之深

in the universe,
都受到了这颗暗淡的光点的挑战
are challenged by this point of pale light.
我们的星球...
Our planet...
只是这个包罗万象的
is a lonely speck in the great,
宇宙中一个小点
enveloping cosmic dark.
我们无从知晓
In our obscurity,
在这广袤宇宙中
in all this vastness,
是否会有来自别处的帮助
there is no hint that help will come from elsewhere
把我们从自己手中拯救
to save us from ourselves.
地球是迄今为止唯一已知存在生命的星球
The Earth is the only world known so far to harbor life.
至少在近期的未来
There is nowhere else,
没有别的星球
at least in the near future,
可供人类移居
to which our species could migrate.
可以去探测
Visit, yes.
