与摩根·弗里曼一起穿越虫洞（2010）

Through The Wormhole With Morgan Freeman S02E02

一个充满能量的地方
an energy site of that landscape.
那里有无限多的人
There is an infinite number of people
可以尝试入住这些房♥间
that can try to check in into these hotel rooms.
我试着进入里面
I try to go into a room,
然后我发现这个充满能量的地方已经被占了
and I discover that energy site is taken.
其他人已经在里面了
Someone else is there.
一旦宇宙在那能量点诞生
Once a Universe is born in that energy site,
首先，这个能量点
first, that energy site
不能和其他宇宙分享了
cannot be shared with another Universe.
所以我尝试到另一个房♥间
So I try to go to the next room.
直到我发现一个空房♥
Until I find an empty room.
这个房♥间热得沸腾，所以它充满着能量
That room is really boiling hot, so it contains a lot of energy.
一旦我进入，我就不能出来了
Once I am in the room, I cannot get out of it anymore.
房♥间门被锁住了，这就是宇宙如何诞生的
The door is locked. That's how the Universe is born.
但如果我们的宇宙像酒店房♥
But if our Universe is like a hotel room,
难道我们不能察觉到
shouldn't we be able to detect the presence of guests
隔壁房♥间里有其他客人吗？
in the room next door?
那些零碎的证据
That earth-shattering evidence
会像这个小小蓝布块一样难以捉摸
could look as subtle as this small blue patch.
2007年，威尔金森探测器的数据
In 2007, data from the WMAP spacecraft
确认了宇宙微波背景辐射里
confirmed the presence of a strange, cold spot
的一些奇怪的冷区
in the cosmic microwave background.
如果我有一些宇宙里空白的区域
If I have an empty region of space,
那应该就是一些低温的区域
that would show as a cold temperature region.
就这些寒冷的区域来说
In the case of the cold spot,
就像天空里
the only way such a part of the sky
一块完全虚无的地方
could just be completely, entirely empty,
这种宇宙里的奇怪特性
that kind of bizarre behavior of the Universe
肯定是因为一些其他力量造成的
can occur only if there is some other force at work.
劳拉认为这个冷区
Laura believes the cold spot
就是另一个临近宇宙存在的证据
is evidence of another Universe right next to ours,
它巨量的物质产生的引力牵引着我们世界的边缘
its enormous mass pulling on matter at the edge of our world.
如果有一些巨量的物质在隔壁房♥间里
If there are some very massive objects in the next room --
换个方式来说，在隔壁宇宙里
in other words, in the neighboring Universe --
那我应该会感觉到引力的牵引
then I should be able to feel that gravitational pull,
尽管我不能直接看到它
although I cannot directly see it.
但对于这激进的理论
But for a theory as radical
证明另一个宇宙的存在
as the existence of another Universe,
单单冷区来说并不足够
the cold spot alone is not enough.
劳拉需要更多的证据
Laura needs more evidence.
援手来了
And help is at hand.
两个科学家加入了
Two scientists are about to join forces
以不同寻常的努力
in a remarkable endeavor
去发现我们宇宙的大小和形状
to find the size and shape of our Universe
而我们隔壁的宇宙
and the Universe next door.
是无限的宇宙吗？
Is the Universe infinite?
或者它也有个边界
Or does it have an edge?
或者我们的宇宙
Or is our Universe just one member
只是宇宙大家族的一个成员
of a cosmic family of Universes,
分布在陌生的版图上？
spread across a strange and uncharted landscape?
就在几年前
Just a few years ago,
就算问这种问题，都是难以置信的
even asking these questions was unthinkable.
但我们离答案很近了
Now we're close to finding the answer.
莎莎确信
Sasha Kashlinsky is convinced
那些在我们宇宙边缘的神秘力量
that some mysterious attractor at the edge of our Universe
正牵引着我们的星系
is pulling on galaxies,
把它们拉向被称为暗流的地方
forcing them to move with what he calls "dark flow."
他的工作还很有争论性
His work is still controversial,
为了取信怀疑论者，他需要更多的证据
and to convince the skeptics, he needs more data.
我们希望，在几年内
We hope, in a few years,
能把2千个星系簇记录进来
to have a catalog of up to 2,000 galaxy clusters in total.
在新的数据里面，我们希望能够
And with the new data, we hope that we'll be able
在更大的尺度上测量这种流动
to measure the flow to much larger scales.
但莎莎现在有强大的支持者了
But Sasha now has a powerful ally.
离多伦多1千英里之外
1,000 miles away, in Toronto,
劳拉·梅尔西尼·霍顿用自己的计算定义了
Laura Mersini-Houghton was defining her own calculations
宇宙的边缘
about the edge of the Universe
当她收到母亲的来电
when she got a phone call from her mother.
她说，你看新闻了吗？
And she says to me, "Did you see the news
一些被称为暗流或其他什么的东西
"about something called dark flow or another?
有美国宇航局的人员在那儿
There was a NASA person there."
我说，不，我没有
And I said, "No, I haven't."
所以我直接来的计算机前
So I went straight into my computer
找到了美国宇航局里莎莎·卡什林斯基领导的团队
and found out that a team at NASA led by Sasha Kashlinsky
报道称他们看见了
had reported they had seen the dark flow
宇宙结构里的暗流
of structure in the Universe.
那真是对我们两年前的预测
That was exactly in perfect agreement
的极好的赞同
with the prediction we had made two years ago.
而令人感觉诡异的是
But what made it spookier was that even the numbers,
那些星系运行的速度
the speed at which those galaxies were moving
和移♥动♥的方向
and the direction into which they were moving
在天文学上完全的
were in absolute perfect agreement astronomically
印证了我们的预测
with our predictions.
现在劳拉和莎莎都在深思
Now Laura and Sasha are both contemplating
那些我们宇宙之外的奇异图景
just how this exotic landscape outside our Universe
会是怎么样的
might behave.
我们把这块板想象成宇宙之外的图景
I can think of this board as the landscape,
能量在这些宇宙的
the energy sites onto which
能量集里
these wave pockets of the Universe
最终会平静下来
will eventually settle.
现在我把这些能量集
Now, I have to send the wave pockets
发送到这个地带里
through that landscape, through that board
使它落户
in order to populate it.
把这弹子想象成
Think of this marble
引发我们大爆♥炸♥的能量脉动
as the pulse of energy that triggered our Big Bang.
很快，另一个能量脉动来到了
Soon, another pulse of energy comes along.
它掉进了另一个小坑里
It falls into a different dip,
然后，临近的宇宙诞生了
and a neighboring Universe is born.
那样的宇宙不是我们能涉足的
That Universe is not a place we can ever go.
它们维度的分布
Its arrangement of dimensions
和我们的完全不同
will be completely different from ours.
但我们有一个唯一的方法去感觉它的存在
But there is one way we can sense its presence.
如果两个宇宙足够接近的话
If the two Universes are close enough together,
它们的引力会把所有物质拉在一起
their gravitational attraction will pull anything with mass
拉向它们各自的边缘
towards their respective edges.
那就是为什么我们看见冷区
That's why we see the cold spot
而且为什么有星系组成的
and that's why there's a dark flow of galaxies
穿越宇宙的暗流
moving across the cosmos.
那是因为其他宇宙在拉动我们的
This other Universe is pulling on ours.
大约3，4年前
Until about three, four years ago,
我们对多重宇宙一无所知
we knew nothing of the multiverse.
但是，在近几年
However, things are changing dramatically
这已经有了显著的变化
in the last few years.
科技帮助我们去发现
Technology is helping us find signatures
多重宇宙存在的印记
of the existence of the multiverse.
但对于世界范围的宇宙学科来说
But across the world of cosmology,
对于这种富争议性的工作
the reactions to these scientists' controversial work
有各种各样的反应
is mixed.
如果他们有一个是对的
If any one of them is right,
牵涉的影响会非常巨大
the implications would be enormous.
为什么我们需要关心宇宙的大小和形状？
Why do we even care about the size and shape of the Universe?
因为里面的内容很重要
That part of the story is critical
对我们试图理解它从何而来
for our attempts to understand how it all came into being,
为什么它会这样
why it is the way it is,
为什么我们周围看起来是这样的
and why we see what we see around us.
这些都有不同的答案
All these questions have very different answers
如果我们能探索到无限当中包含什么
if we're looking at the infinite story
或有限当中包含什么
or the finite story.
我们就能够说，看，这就是宇宙
We'd be able to say, "Look, here is the Universe.
这就是它的形状，就是我们生活的地方
This is its shape. And that's where we live."
