The Digital Universe,
2
4000
2000
数字宇宙。
00:21
which was created for humanity
3
6000
2000
它是为了让人类
00:23
to really see where we are
4
8000
2000
能真正看到我们在宇宙
00:25
in the universe.
5
10000
3000
的何处。
00:28
And so I think we can roll the video that we have.
6
13000
2000
我想我们可以开始播放了。

The flat horizon that we've evolved with
9
20000
3000
Carter Emmart（卡特·艾玛特）：我们看到水平地平线
00:38
has been a metaphor for the
10
23000
2000
象征着
00:40
infinite: unbounded resources
11
25000
2000
无穷无尽的资源
00:42
and unlimited capacity
12
27000
2000
和无限的能力，
00:44
for disposal of waste.
13
29000
3000
由我们充分使用的未利用的资源。
00:47
It wasn't until we really
14
32000
2000
直到我们真的
00:49
left Earth,
15
34000
2000
离开了地球，
00:51
got above the atmosphere
16
36000
2000
来到大气层之上
00:53
and had seen the horizon
17
38000
2000
看到地平线
00:55
bend back on itself,
18
40000
3000
向后弯曲，
00:58
that we could understand our planet
19
43000
2000
我们才明白我们的地球
01:00
as a limited condition.
20
45000
3000
处于一种极限状态。
01:04
The Digital Universe Atlas
21
49000
3000
数字宇宙的地图集
01:09
has been built
22
54000
2000
已经被制作，
01:11
at the American Museum of Natural History
23
56000
3000
在过去的12年里
01:14
over the past 12 years.
24
59000
3000
并放在美国自然历史博物馆。
01:17
We maintain that,
25
62000
2000
我们保持了这个地图集，
01:19
put that together
26
64000
2000
并建立一个项目
01:21
as a project
27
66000
2000
将地图集合在一起，
01:23
to really chart the universe
28
68000
2000
从各个不同的范围
01:25
across all scales.
29
70000
2000
真正意义上地绘制宇宙。
01:29
What we see here are satellites around the Earth
30
74000
3000
我们在这里看到的是围绕地球的卫星，
01:32
and the Earth in proper registration
31
77000
3000
以及地球在宇宙中
01:35
against the universe, as we see.
32
80000
3000
的固定位置，正如我们所看到的。
01:42
NASA supported this work
33
87000
2000
美国国家航空和宇宙航行局，12年前
01:44
12 years ago
34
89000
3000
将此工作
01:47
as part of the rebuilding
35
92000
2000
作为重建
01:49
of the Hayden Planetarium
36
94000
2000
Hayden Planetarium（海登天文馆）的部分，
01:51
so that we would share this with the world.
37
96000
3000
让我们能与世界分享。
01:54
The Digital Universe is the basis
38
99000
2000
以数字宇宙作为空间的
01:56
of our space show productions that we do --
39
101000
2000
基础，来展示我们的产品 --
01:58
our main space shows in the dome.
40
103000
3000
我们主要的空间展示在这个穹顶内。
02:01
But what you see here
41
106000
2000
但你们在这里看到的
02:03
is the result of, actually, internships
42
108000
2000
成果出自于现在的实习项目，
02:05
that we hosted with Linkoping University
43
110000
3000
是我们与Linkoping（林雪平）大学在瑞典
02:08
in Sweden.
44
113000
2000
共同主办的。
02:10
I've had 12 students work on this
45
115000
3000
我们有12个学生为此项目工作，
02:13
for their graduate work,
46
118000
2000
作为他们的毕业项目。
02:15
and the result has been this software called Uniview
47
120000
3000
而最后的成果是这个叫做Uniview（宇宙观探）的软件
02:18
and a company called SCISS in Sweden.
48
123000
3000
和在一个叫SCISS的瑞典公司。
02:22
This software
49
127000
2000
这个软件
02:24
allows interactive use,
50
129000
3000
允许交互式的使用。
02:27
so this actual flight path
51
132000
2000
所以这个真实的飞行轨迹
02:29
and movie that we see here
52
134000
2000
和我们这里看到的影片
02:31
was actually flown live.
53
136000
2000
实际上是飞行的实况。
02:33
I captured this live from my laptop
54
138000
3000
我在我的笔记本电脑上捕捉到了这个实况，
02:36
in a cafe called Earth Matters
55
141000
3000
在一个叫做Earth Matters（地球事务）的咖啡馆里，
02:39
on the Lower East Side of Manhattan, where I live,
56
144000
3000
在曼哈顿的下东部，也就是我生活的地方。
02:42
and it was done
57
147000
2000
它作为一个合作项目
02:44
as a collaborative project
58
149000
2000
被完成了。
02:46
with the Rubin Museum of Himalayan Art
59
151000
3000
是与鲁宾博物馆的喜马拉雅艺术合作
02:49
for an exhibit
60
154000
3000
来完成一个展览，
02:52
on comparative cosmology.
61
157000
3000
展示比较宇宙学。
02:56
And so as we move out,
62
161000
2000
正如我们逐渐迁出，
02:58
we see continuously from our planet
63
163000
3000
我们从我们的行星逐渐看到
03:01
all the way out into the realm of galaxies, as we see here,
64
166000
3000
并一直延伸到我们这里所看到的真正的星系，
03:04
light-travel time, giving you a sense of how far away we are.
65
169000
3000
光时旅行，让你感觉到我们所处有多遥远。
03:09
As we move out,
66
174000
2000
当我们离开，
03:11
the light from these distant galaxies
67
176000
2000
从那些遥远星系发出的光
03:13
have taken so long,
68
178000
2000
用了如此长的时间，
03:15
we're essentially backing up into the past.
69
180000
3000
本质上我们正在回到过去。
03:18
We back so far up
70
183000
2000
我们回到非常早以前，
03:20
we're finally seeing a containment around us --
71
185000
3000
我们最终能看见围绕我们存在的密闭空间 --
03:23
the afterglow of the Big Bang.
72
188000
2000
也就是宇宙大爆炸后的余晖。
03:25
This is the WMAP
73
190000
2000
这是威尔金森微波各向异性探测器
03:27
microwave background
74
192000
2000
的微波背景，
03:29
that we see.
75
194000
2000
正如我们看到的。
03:31
We'll fly outside it here, just to see this sort of containment.
76
196000
3000
我们将飞出此处，来看这一密闭空间。
03:34
If we were outside this,
77
199000
2000
如果我们在此之外，
03:36
it would almost be meaningless, in the sense as before time.
78
201000
3000
其实是毫无意义的，因为这意味着在时间之前。
03:39
But this our containment of the visible universe.
79
204000
3000
但是，这就是我们可视宇宙的密闭空间。
03:42
We know the universe is bigger than that which we can see.
80
207000
2000
我们知道宇宙比我们所看见的要大。
03:44
Coming back quickly,
81
209000
2000
快速返回，
03:46
we see here the radio sphere that we jumped out of in the beginning,
82
211000
3000
我们这里看到的就是最初我们跳离的放射领域。
03:49
but these are positions,
83
214000
2000
但这些位置是
03:51
the latest positions of exoplanets
84
216000
3000
我们所绘制的
03:54
that we've mapped,
85
219000
2000
系外行星的最新位置。
03:56
and our sun here, obviously, with our own solar system.
86
221000
3000
这里我们的太阳显然是在太阳系之内的。
04:01
What you're going to see -- we're going to have to jump in here pretty quickly
87
226000
3000
即将看到的是-你们即将迅速跳进此处，
04:04
between several orders of magnitude
88
229000
2000
介乎几个数量级之间，
04:06
to get down to where we see the solar system --
89
231000
2000
来回到我们能看到太阳系的地方。
04:08
these are the paths of
90
233000
2000
这些轨迹是
04:10
Voyager 1, Voyager 2, Pioneer 11 and Pioneer 10,
91
235000
3000
旅行者一号，旅行者二号，先驱者11号和先驱者10号，
04:13
the first four spacecraft to have left the solar system.
92
238000
3000
四个最先离开太阳系的宇宙飞船。
04:18
Coming in closer,
93
243000
2000
离得更近点，
04:20
picking up Earth,
94
245000
3000
到达地球。
04:24
orbit of the Moon, and we see the Earth.
95
249000
3000
这是月球的轨迹，而现在我们看见的是地球。
04:30
This map can be updated,
96
255000
3000
这个地图可以被更新。
04:33
and we can add in new data.
97
258000
2000
而且我们可以置入新的数据。
04:35
I know Dr. Carolyn Porco is the camera P.I.
98
260000
2000
我知道Carolyn Porco（卡洛琳·波尔科）博士是摄影私人调查员，
04:37
for the Cassini mission.
99
262000
2000
为Cassini（卡西尼）探测录工作。
04:39
But here we see the complex trajectory
100
264000
2000
但是我们这里看到的是来自于卡西尼探测录
04:41
of the Cassini mission
101
266000
2000
复杂的轨道，
04:43
color coded for different mission phases,
102
268000
2000
以不同的颜色标记不同的飞行阶段，
04:45
ingeniously developed so that
103
270000
2000
巧妙的展开。
04:47
45 encounters with the largest moon, Titan,
104
272000
2000
因此45次与最大的卫星-Titan（提坦）相遇，
04:49
which is larger that the planet Mercury,
105
274000
2000
而它比水星还要大，
04:51
diverts the orbit into different parts of mission phase.
106
276000
3000
将轨道划分为飞行阶段的不同部分。
04:56
This software allows us to come close
107
281000
2000
这个软件能让我们离得更近
04:58
and look at parts of this.
108
283000
3000
的看到其中的部分。
05:01
This software can also be networked between domes.
109
286000
3000
这个软件能用互联网在宿舍之间连接。
05:04
We have a growing user base of this,
110
289000
2000
而这一软件的用户正在增长。
05:06
and we network domes.
111
291000
2000
并且我们还在连接其它的学生宿舍。
05:08
And we can network between domes and classrooms.
112
293000
3000
还可以在宿舍与教室之间联网。
05:12
We're actually sharing tours of the universe
113
297000
3000
事实上，我们分享的是宇宙的旅行，
05:15
with the first sub-Saharan
114
300000
2000
先与撒哈拉沙漠以南的地区
05:17
planetarium in Ghana
115
302000
2000
的加纳天文馆，
05:19
as well as
116
304000
2000
与此同时
05:21
new libraries that have been built
117
306000
2000
与哥伦比亚少数族群区
05:23
in the ghettos in Columbia
118
308000
2000
新建立的图书馆
05:25
and a high school
119
310000
2000
以及位于柬埔寨
05:27
in Cambodia.
120
312000
2000
一个高中。
05:29
And the Cambodians have
121
314000
2000
柬埔寨已经
05:31
actually controlled the Hayden Planetarium from their high school.
122
316000
3000
能从高中登录海登天文馆。
05:35
This is an image from Saturday,
123
320000
2000
这是周六拍摄的一张图像，
05:37
photographed by the Aqua satellite, but through the Uniview software.
124
322000
3000
它由水资源监测太空器拍摄，和用Uniview（宇宙观探）软件。
05:40
So you're seeing the edge of the Earth.
125
325000
2000
所以你们看见的是地球的边缘。
05:42
This is Nepal.
126
327000
2000
这是尼泊尔。
05:44
This is, in fact, right here is the valley of Lhasa,
127
329000
3000
这是，实际上，这里是拉萨的谷地，
05:47
right here in Tibet.
128
332000
3000
就在西藏。
05:50
But we can see the haze
129
335000
2000
但是我们可以看到薄雾
05:52
from fires and so forth in the Ganges valley
130
337000
2000
来自于恒河谷地的火源等等
05:54
down below in India.
131
339000
2000
向下刮向印度。
05:56
This is Nepal and Tibet.
132
341000
3000
这是尼泊尔和西藏。
06:00
And just in closing,
133
345000
3000
就到这里。
06:03
I'd just like to say this beautiful world that we live on --
134
348000
3000
我想说，在我们所居住的这个美丽的世界 --
06:08
here we see a bit of the snow
135
353000
2000
这里我们看见一点雪
06:10
that some of you may have had to brave in coming out --
136
355000
3000
而你们中的一些人出来的时候可能就得勇敢点。
06:15
so I'd like to just say
137
360000
2000
我只想说
06:17
that what the world needs now
138
362000
2000
世界现在需要的
06:19
is a sense of being able to
139
364000
2000
是在某种意义上，能够
06:21
look at ourselves in this much larger condition now
140
366000
3000
在全局下现在审视我们自己
06:24
and a much larger sense of what home is.
141
369000
3000
以及广义上了解什么是家。
06:27
Because our home is the universe,
142
372000
2000
因为我们的家正是宇宙，
06:29
and we are the universe, essentially.
143
374000
2000
而我们本质上就是宇宙。
06:31
We carry that in us.
144
376000
2000
我们将宇宙带到我们身边。
06:33
And to be able to see our context
145
378000
3000
然后能够看我们所处何处
06:36
in this larger sense at all scales
146
381000
3000
从广义上，从各个不同的角度
06:39
helps us all, I think, in understanding
147
384000
2000
我想，这帮助我们理解
06:41
where we are and who we are in the universe.
148
386000
2000
在宇宙中我们身处何处以及我们是谁
06:43
Thank you.
149
388000
2000
谢谢。
06:45
(Applause)

ABOUT THE SPEAKER
Carter Emmart - Scientist, ArtistCarter Emmart uses astronomy and computational modeling to create scientifically accurate, three-dimensional tours of our universe.
Why you should listen
As the Director of Astrovisualization at the American Museum of Natural History, Carter Emmart directs their groundbreaking space shows and heads up development of an interactive 3D atlas called The Digital Universe. He coordinates scientists, programmers and artists to produce scientifically accurate yet visually stunning and immersive space experiences in the AMNH’s Hayden Planetarium. Over the last decade, he has directed four shows: Passport to the Universe, The Search for Life: Are we Alone?, Cosmic Collisions and Journey to the Stars.
Emmart’s interest in space began early, and at ten he was taking astronomy courses in the old Hayden. As a child born into a family of artists, he naturally combined his love of science with his tendency for visualization. His first work was in architectural modeling, soon moving on to do scientific visualization for NASA and the National Center for Atmospheric Research, before joining the AMNH.
