to share with you

和大家分享

The Digital Universe,

數字化宇宙

which was created for humanity

它的誕生是為了讓全人類

to really see where we are

能夠真實地看到我們

in the universe.

在宇宙中的位置。

And so I think we can roll the video that we have.

因此我們現在就可以看看這個視頻。

The flat horizon that we've evolved with

Carter Emmart旁白：一直以來我們所感受到的地平線

has been a metaphor for the

恰似一個隱喻

infinite: unbounded resources

認為人有無窮無盡的資源

and unlimited capacity

無限的能力

for disposal of waste.

可以無節制地丟棄垃圾。

It wasn't until we really

直到我們真正地

left Earth,

離開地球，

got above the atmosphere

到達大氣層之上，

and had seen the horizon

看到這個地平線

bend back on itself,

彎曲成一個球，

that we could understand our planet

我們才會意識到我們的星球

as a limited condition.

是有限的。

The Digital Universe Atlas

數字化宇宙圖

has been built

構建於

at the American Museum of Natural History

美國自然歷史博物館

over the past 12 years.

已走過12個年頭。

We maintain that,

我們堅持不懈

put that together

積思廣益

as a project

令這個項目

to really chart the universe

可以真實地繪製出

across all scales.

各種比例下的宇宙。

What we see here are satellites around the Earth

這裡我們看到的是環繞地球的衛星，

and the Earth in proper registration

以及地球在整個宇宙中的

against the universe, as we see.

恰當位置。

NASA supported this work

NASA支持這項工作

12 years ago

已長達12年，

as part of the rebuilding

將其作為重建

of the Hayden Planetarium

海登天文館的一部份

so that we would share this with the world.

因而我們可以和全世界分享這個成果。

The Digital Universe is the basis

數字化宇宙基本上就是

of our space show productions that we do --

我們的空間展示節目，

our main space shows in the dome.

其播放的空間是個穹頂大廳。

But what you see here

但是你在這裡看到的

is the result of, actually, internships

事實上是實習計劃的成果

that we hosted with Linkoping University

即我們在Linkoping大學的一個項目

in Sweden.

在瑞典。

I've had 12 students work on this

我有12個學生為這個項目工作

for their graduate work,

這也是他們的研究生課題。

and the result has been this software called Uniview

成果就是這個成為“全宇視野”的軟件

and a company called SCISS in Sweden.

以及在瑞典成立的公司，叫SCISS。

This software

這個軟件

allows interactive use,

允許交互使用。

so this actual flight path

所以這道飛行軌跡

and movie that we see here

以及我們這裡看到的所有影像

was actually flown live.

都是真實發生過的。

I captured this live from my laptop

我從我的筆記本電腦上捕捉到這個真實片段

in a cafe called Earth Matters

就在一個叫“地球很重要”的咖啡館裡，

on the Lower East Side of Manhattan, where I live,

位於曼哈頓的下東部，也就是我住的地方。

and it was done

所以

as a collaborative project

這是一個多方合作的計劃

with the Rubin Museum of Himalayan Art

會同（紐約的）魯賓喜馬拉雅藝術博物館

for an exhibit

聯合展出

on comparative cosmology.

主題是比較宇宙學。

And so as we move out,

就這樣，當我們從地球出發

we see continuously from our planet

從地球不斷

all the way out into the realm of galaxies, as we see here,

看向宇宙的各個方向，正如這裡所展示的，

light-travel time, giving you a sense of how far away we are.

光速可以讓你感受到現在距地球有多遙遠。

As we move out,

當我們繼續前進，

the light from these distant galaxies

來自這些 遙遠星系的光

have taken so long,

已經走了非常遠，

we're essentially backing up into the past.

我們其實是在跟進這些光的過去。

We back so far up

當我們越跟越近，

we're finally seeing a containment around us --

最終我們會看到被一個容器所包圍——

the afterglow of the Big Bang.

就是宇宙大爆炸的余輝。

This is the WMAP

也就是W圖，

microwave background

微波背景

that we see.

就如我們現在所見。

We'll fly outside it here, just to see this sort of containment.

現在我們將飛越它，就會看到這個容器。

If we were outside this,

如果我們跳到這個背景之外，

it would almost be meaningless, in the sense as before time.

那幾乎是無意義的，所謂在時間開始之前。

But this our containment of the visible universe.

但是這就是我們可見宇宙的邊界。

We know the universe is bigger than that which we can see.

我們知道宇宙要比我們所能看到的大得多。

Coming back quickly,

迅速回到地球，

we see here the radio sphere that we jumped out of in the beginning,

這裡是我們最先出發的無線電波區域

but these are positions,

但是這些位置，

the latest positions of exoplanets

是最新的太陽系外行星

that we've mapped,

我們已經製作到圖中。

and our sun here, obviously, with our own solar system.

顯然這裡是我們的太陽和太陽系。

What you're going to see -- we're going to have to jump in here pretty quickly

你們即將看到的——這裡必須快速跳躍

between several orders of magnitude

透過不同量級的尺度

to get down to where we see the solar system --

看我們的太陽系。

these are the paths of

這些飛行軌跡屬於

Voyager 1, Voyager 2, Pioneer 11 and Pioneer 10,

旅行者1號，旅行者2號，先鋒11號和先鋒10號，

the first four spacecraft to have left the solar system.

最早離開太陽系的四艘宇宙飛船。

Coming in closer,

再靠近些，

picking up Earth,

看看地球。

orbit of the Moon, and we see the Earth.

在月球的運行軌道上，我們看地球。

This map can be updated,

這張圖是可以更新的。

and we can add in new data.

我們可以添加新數據。

I know Dr. Carolyn Porco is the camera P.I.

我知道Carolyn Porco 博士是

for the Cassini mission.

卡西尼計劃的成像系統的首席研究員。

But here we see the complex trajectory

但是這裡我們看到的複雜軌道

of the Cassini mission

屬於整個卡西尼計劃，

color coded for different mission phases,

不同的顏色區分了該計劃的不同階段，

ingeniously developed so that

該計劃的推進極其精密巧妙，

45 encounters with the largest moon, Titan,

它45次與土星的最大衛星泰坦相遇，

which is larger that the planet Mercury,

泰坦甚至大過水星，

diverts the orbit into different parts of mission phase.

它把泰坦的運行軌跡劃分為該計劃的不同階段。

This software allows us to come close

這套軟件讓我們能更靠近

and look at parts of this.

觀察這些不同部份。

This software can also be networked between domes.

它還可以在不同的天文館間聯網使用。

We have a growing user base of this,

我們的基礎用戶群還在擴大。

and we network domes.

我們連接起這些天幕。

And we can network between domes and classrooms.

而且我們還能讓天幕和教室聯網。

We're actually sharing tours of the universe

我們的宇宙之旅可以在多處同時展開，

with the first sub-Saharan

無論是撒哈拉以南的第一座天文館

planetarium in Ghana

加納的天文館

as well as

還有

new libraries that have been built

建在哥倫比亞貧民窟的

in the ghettos in Columbia

新圖書館，

and a high school

以及柬埔寨的

in Cambodia.

某所中學。

And the Cambodians have

而且柬埔寨的同學們

actually controlled the Hayden Planetarium from their high school.

確實可以從他們的學校控制海登天文館。

This is an image from Saturday,

這是星期六拍攝的一副圖像，

photographed by the Aqua satellite, but through the Uniview software.

透過Aqua衛星（NASA的多國科學衛星），但是用的是“全宇視野”軟件。

So you're seeing the edge of the Earth.

所以這裡看到的是地球的邊緣。

This is Nepal.

這是尼泊爾。

This is, in fact, right here is the valley of Lhasa,

這裡事實上是拉薩谷地，

right here in Tibet.

就位於西藏。

But we can see the haze

from fires and so forth in the Ganges valley

來自恒河谷地燃燒的火等等，

down below in India.

就在印度的南部。

This is Nepal and Tibet.

這裡是尼泊爾和西藏。

And just in closing,

最後，

I'd just like to say this beautiful world that we live on --

我想說，我們居住的這個美麗的星球——

here we see a bit of the snow

這裡能看到些積雪，

that some of you may have had to brave in coming out --

在座有人可能曾經勇敢地到達過那裡。

so I'd like to just say

我只是想說，

that what the world needs now

現在這個世界所需要的

is a sense of being able to

是讓我們能夠

look at ourselves in this much larger condition now

像這樣從更大的背景回望我們自己，

and a much larger sense of what home is.

從更廣大的空間看看我們的家園。

Because our home is the universe,

因為我們的家就是宇宙，

and we are the universe, essentially.

根本上來說我們就是宇宙。

We carry that in us.

宇宙就蘊含在我們中。

And to be able to see our context

能夠看到我們身處的宇宙

in this larger sense at all scales

以各種更大的尺度來看，

helps us all, I think, in understanding

我認為有助于讓我們理解

where we are and who we are in the universe.

在宇宙中，我們在哪裡，我們是誰。

Thank you.

謝謝大家。
