Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:12,913 --> 00:00:16,417
WILL SMITH: What do you need
to win a game of chess?
2
00:00:16,450 --> 00:00:21,489
Patience, clever tactics,
loads of imagination.
3
00:00:21,522 --> 00:00:22,723
You look nervous.
4
00:00:22,756 --> 00:00:23,724
(laughs)
5
00:00:23,757 --> 00:00:25,093
What makes us human
6
00:00:25,126 --> 00:00:28,862
is the squishy triple-pounder
inside our heads.
7
00:00:30,864 --> 00:00:31,832
Check.
8
00:00:31,865 --> 00:00:34,068
It lets us checkmate
our friends,
9
00:00:34,102 --> 00:00:35,736
build skyscrapers,
10
00:00:35,769 --> 00:00:39,840
and lift a special few of us
into space.
11
00:00:39,873 --> 00:00:44,712
(roaring)
12
00:00:44,745 --> 00:00:50,618
Eight astronauts with over 1,000
days in space between them
13
00:00:50,651 --> 00:00:53,621
can tell us how being up there
14
00:00:53,654 --> 00:00:57,658
helped them to truly understand
what goes on down here.
15
00:01:00,094 --> 00:01:02,029
JEFF HOFFMAN: From space
you get the big picture.
16
00:01:02,062 --> 00:01:04,598
You really see
human civilization
17
00:01:04,632 --> 00:01:08,136
spread out below you.
18
00:01:08,169 --> 00:01:09,637
NICOLE STOTT: As far as we know,
19
00:01:09,670 --> 00:01:14,475
there's nobody else like us
out there in the universe.
20
00:01:14,508 --> 00:01:16,877
JERRY LINENGER: The only reason
I'm able to comprehend
21
00:01:16,910 --> 00:01:19,913
the incredible complexity
of the Earth
22
00:01:19,947 --> 00:01:25,886
is because I have an incredibly
complex brain inside my head.
23
00:01:25,919 --> 00:01:28,889
LELAND MELVIN: We are the only
species on this planet
24
00:01:28,922 --> 00:01:33,627
that can construct
realities in our mind
25
00:01:33,661 --> 00:01:35,763
and then go actually build it.
26
00:01:37,998 --> 00:01:40,634
SMITH: But for
three billion years,
27
00:01:40,668 --> 00:01:43,171
life didn't even have a brain.
28
00:01:45,673 --> 00:01:47,908
MELVIN: The story of how
our mind evolved
29
00:01:47,941 --> 00:01:50,144
on this one strange rock
30
00:01:50,178 --> 00:01:54,515
is one of chance, coincidence
and impossible odds.
31
00:01:59,553 --> 00:02:03,691
SMITH: I am going to tell you
about the most incredible place.
32
00:02:03,724 --> 00:02:06,527
The weird connections,
33
00:02:06,560 --> 00:02:10,831
the dynamic forces
that created us.
34
00:02:12,833 --> 00:02:19,006
A species with a brain as
complex as yours and mine.
35
00:02:19,039 --> 00:02:25,979
(music)
36
00:02:29,683 --> 00:02:33,654
(music)
37
00:02:33,687 --> 00:02:39,660
(music)
38
00:02:39,693 --> 00:02:45,966
(music)
39
00:02:45,999 --> 00:02:48,936
The human brain is unique.
40
00:02:52,172 --> 00:02:56,377
Not just because of its size,
but also its ability.
41
00:02:58,546 --> 00:03:02,583
It can meet challenges that
are dangerous, demanding.
42
00:03:06,019 --> 00:03:07,688
(laughs)
43
00:03:07,721 --> 00:03:10,524
SMITH: And wonderfully absurd.
44
00:03:10,558 --> 00:03:16,564
(applause)
45
00:03:16,597 --> 00:03:22,536
(applause)
46
00:03:22,570 --> 00:03:26,474
(applause)
47
00:03:51,732 --> 00:03:54,568
(crowd chanting)
48
00:03:54,602 --> 00:03:58,972
SMITH: In Spain, thousands
come together every year
49
00:03:59,006 --> 00:04:03,010
to build towers out of people.
50
00:04:19,993 --> 00:04:25,799
SMITH: A ten-story human tower
with the youngest kids on top.
51
00:04:25,833 --> 00:04:27,768
Right.
52
00:04:27,801 --> 00:04:30,971
Claudia and Marina,
they're seven.
53
00:04:53,494 --> 00:04:56,797
(crowd gasps)
54
00:04:56,830 --> 00:04:59,833
(music)
55
00:04:59,867 --> 00:05:05,973
(music)
56
00:05:06,006 --> 00:05:11,512
(music)
57
00:05:11,545 --> 00:05:13,847
(crowd gasps)
58
00:05:17,050 --> 00:05:22,823
(applause)
59
00:05:22,856 --> 00:05:26,927
(music)
60
00:05:36,737 --> 00:05:40,741
(music)
61
00:05:40,774 --> 00:05:46,980
(music)
62
00:05:47,014 --> 00:05:53,687
(music)
63
00:06:10,804 --> 00:06:12,773
(music)
64
00:06:12,806 --> 00:06:19,212
(music)
65
00:06:19,246 --> 00:06:25,753
(clapping)
66
00:06:25,786 --> 00:06:29,790
(applause)
67
00:06:29,823 --> 00:06:35,763
(music)
68
00:06:35,796 --> 00:06:41,802
(cheering)
69
00:06:41,835 --> 00:06:47,941
(cheering)
70
00:06:47,975 --> 00:06:54,882
(cheering)
71
00:06:54,915 --> 00:07:01,589
(cheering)
72
00:07:01,622 --> 00:07:05,125
SMITH: Humans are like no other
creature on Earth.
73
00:07:05,158 --> 00:07:09,630
We do these things that
might seem pointless,
74
00:07:09,663 --> 00:07:13,967
not because we're stupid;
because we're smart.
75
00:07:14,001 --> 00:07:17,137
And we work as one.
76
00:07:17,170 --> 00:07:21,174
It's that ability to link
our minds together
77
00:07:21,208 --> 00:07:23,977
that put those girls
on top of that tower
78
00:07:24,011 --> 00:07:27,114
and also put men and women
up in space.
79
00:07:30,851 --> 00:07:33,821
One of them is Leland Melvin.
80
00:07:38,692 --> 00:07:44,064
Former NFL player, mechanical
engineer, and astronaut.
81
00:07:46,166 --> 00:07:48,802
Strong, smart, brave,
82
00:07:48,836 --> 00:07:51,839
and pretty much unstoppable.
83
00:07:51,872 --> 00:07:56,644
But Leland nearly didn't
make it to space.
84
00:07:56,677 --> 00:08:00,147
An accident in his training
brought his dreams to a halt.
85
00:08:06,854 --> 00:08:10,223
MELVIN: The only way to really
simulate a spacewalk on Earth
86
00:08:10,257 --> 00:08:12,225
is in a pool.
87
00:08:12,259 --> 00:08:17,898
I remember getting in the suit,
putting my gloves on, my boots.
88
00:08:23,904 --> 00:08:27,641
MELVIN: As you're going down
in the spacesuit,
89
00:08:27,675 --> 00:08:29,610
you have to clear your ears.
90
00:08:35,182 --> 00:08:36,149
MELVIN: Ten feet down,
91
00:08:36,183 --> 00:08:38,886
I realized that
the Styrofoam block,
92
00:08:38,919 --> 00:08:41,021
you press your nose against it
to clear your ears,
93
00:08:41,054 --> 00:08:43,824
was missing in my helmet.
94
00:08:43,857 --> 00:08:47,895
I tell the test director, turn
the volume in the headset up.
95
00:08:47,928 --> 00:08:51,531
I was straining to equalize
the pressure.
96
00:08:53,066 --> 00:08:56,536
And then, I immediately hear
nothing but static.
97
00:08:58,872 --> 00:09:01,809
They were pulling me
out of the water.
98
00:09:04,044 --> 00:09:07,080
And now I see the flight surgeon
walking towards me.
99
00:09:09,549 --> 00:09:11,919
He reaches up and
touches my right ear.
100
00:09:11,952 --> 00:09:15,055
He's moving his lips, but I
don't hear anything he's saying.
101
00:09:17,157 --> 00:09:19,760
And then I can feel the blood
starting to trickle down
102
00:09:19,793 --> 00:09:21,962
on the side of my face.
103
00:09:21,995 --> 00:09:25,966
I'm like, 'Wow, something's
really wrong.'
104
00:09:25,999 --> 00:09:28,068
I was completely deaf.
105
00:09:31,839 --> 00:09:35,809
Somehow the connection
between my brain and my ears
106
00:09:35,843 --> 00:09:38,746
had been severed,
107
00:09:38,779 --> 00:09:42,750
along with my chances
of going to space.
108
00:09:42,783 --> 00:09:48,789
The accident gave me
a profound appreciation
109
00:09:48,822 --> 00:09:52,660
in what we take for granted.
110
00:09:52,693 --> 00:09:57,665
The thing that makes us us:
our brain.
111
00:09:59,833 --> 00:10:02,102
The human brain sets us apart
112
00:10:02,135 --> 00:10:07,107
from all other creatures
on this planet.
113
00:10:07,140 --> 00:10:10,510
It might look like
a lump of Jell-O,
114
00:10:10,543 --> 00:10:13,647
but it's the most complex thing
in our universe.
115
00:10:15,816 --> 00:10:20,854
Inside, there's a vast network
with 100 trillion connections.
116
00:10:22,956 --> 00:10:28,628
That's more than the number
of stars in our own Milky Way.
117
00:10:28,662 --> 00:10:30,698
It hosts our memories.
118
00:10:32,866 --> 00:10:36,136
Our sensations.
119
00:10:36,169 --> 00:10:37,838
Our dreams.
120
00:10:41,174 --> 00:10:46,646
And all this depends on tiny
cells firing electrical signals.
121
00:10:46,680 --> 00:10:50,784
There's 86 billion of them.
122
00:10:50,818 --> 00:10:54,154
We call them neurons.
123
00:10:54,187 --> 00:10:56,623
SMITH: 86 billion.
124
00:10:56,656 --> 00:10:57,825
Wow.
125
00:10:57,858 --> 00:11:00,493
I'm just glad someone else
was counting.
126
00:11:02,529 --> 00:11:04,464
But here's the thing:
127
00:11:04,497 --> 00:11:09,169
most of life on Earth does
just fine without a brain.
128
00:11:12,906 --> 00:11:16,777
I'm talking about some
of Earth's oldest inhabitants.
129
00:11:19,179 --> 00:11:22,015
Some brainless creatures
are so successful,
130
00:11:22,049 --> 00:11:25,819
you can even see them
from space.
131
00:11:25,853 --> 00:11:26,920
LINENGER:
On a bright, sunny day,
132
00:11:26,954 --> 00:11:29,522
I'm looking down,
and for 1,000 miles,
133
00:11:29,556 --> 00:11:33,693
I see an organized city
of coral.
134
00:11:39,566 --> 00:11:43,503
PEGGY WHITSON: They just glow.
135
00:11:43,536 --> 00:11:46,807
It's just like the most
beautiful art in the world.
136
00:11:51,144 --> 00:11:53,747
MELVIN: This burst of color.
137
00:11:55,615 --> 00:11:59,719
I'd never seen colors
that vibrant before.
138
00:11:59,753 --> 00:12:04,591
It's kind of amazing that corals
are vast, motionless structures,
139
00:12:04,624 --> 00:12:06,994
that thrive without a brain.
140
00:12:10,764 --> 00:12:12,900
SMITH: In the country
of the brainless,
141
00:12:12,933 --> 00:12:15,735
the tiny-brained is king.
142
00:12:15,769 --> 00:12:17,404
Meet this little guy.
143
00:12:21,108 --> 00:12:25,078
He's got more in common with us
than you might think.
144
00:12:25,112 --> 00:12:28,849
Inside, he's got neurons, too,
just not as many.
145
00:12:30,951 --> 00:12:32,752
About 200.
146
00:12:32,786 --> 00:12:35,122
Kind of a starter kit.
147
00:12:35,155 --> 00:12:40,460
(music)
148
00:12:40,493 --> 00:12:45,632
He's a baby sea squirt
looking for a home.
149
00:12:45,665 --> 00:12:47,600
His neurons do simple stuff,
150
00:12:47,634 --> 00:12:51,038
like detect light
and twitch his tail.
151
00:12:52,505 --> 00:12:53,974
But here's the thing:
152
00:12:54,007 --> 00:13:00,113
once he's found the right rock,
his swimming days are over.
153
00:13:00,147 --> 00:13:04,117
For the rest of his life,
he stays put.
154
00:13:04,151 --> 00:13:09,789
He dumps the tail and consumes
the neurons that made it move.
155
00:13:09,823 --> 00:13:14,127
Then, it grows into
a big, old sea squirt.
156
00:13:14,161 --> 00:13:19,632
Takes 'use it or lose it'
to a whole new level.
157
00:13:19,666 --> 00:13:21,001
MELVIN: It's kind of a freaky
thought that, you know,
158
00:13:21,034 --> 00:13:25,538
when neurons were developed,
they weren't for thinking.
159
00:13:25,572 --> 00:13:28,808
They were for simple motion
or movement.
160
00:13:28,842 --> 00:13:33,813
But one day, neurons like those,
the ones inside our brains,
161
00:13:33,847 --> 00:13:34,848
would help create things
162
00:13:34,882 --> 00:13:38,485
like rocket ships
going to space,
163
00:13:38,518 --> 00:13:40,988
cities and music.
164
00:13:41,021 --> 00:13:45,825
(music)
165
00:13:45,859 --> 00:13:49,796
SMITH: Making a tail twitch
to move a yard or two
166
00:13:49,829 --> 00:13:52,532
requires just a few neurons.
167
00:13:52,565 --> 00:13:54,801
However,
the more advanced stuff,
168
00:13:54,834 --> 00:13:58,538
that needs an awful lot more.
169
00:13:58,571 --> 00:14:01,641
Life needs to sense
its surroundings,
170
00:14:01,674 --> 00:14:05,378
otherwise, it's just flailing
around in the dark.
171
00:14:15,956 --> 00:14:20,160
SMITH: There is nothing more
complex than the human brain.
172
00:14:20,193 --> 00:14:23,096
But the more complicated
something is,
173
00:14:23,130 --> 00:14:25,732
the more ways it can go wrong.
174
00:14:25,765 --> 00:14:26,733
(bird shrieks)
175
00:14:28,768 --> 00:14:30,737
MELVIN:
After my training accident,
176
00:14:30,770 --> 00:14:34,607
the doctors couldn't figure out
what was wrong with me.
177
00:14:34,641 --> 00:14:37,844
Everything looked
physically intact,
178
00:14:37,877 --> 00:14:40,180
but they couldn't fix me.
179
00:14:40,213 --> 00:14:43,750
I was completely deaf.
180
00:14:43,783 --> 00:14:48,121
My goal of getting to space
seemed to be thwarted.
181
00:14:48,155 --> 00:14:49,722
But all I could think about
182
00:14:49,756 --> 00:14:53,726
was whether I'd ever hear
music that I played again.
183
00:14:53,760 --> 00:14:56,896
Music has been such
a big part of my life.
184
00:14:56,930 --> 00:14:59,899
(playing piano)
185
00:14:59,933 --> 00:15:03,003
And so, when the music
was silent...
186
00:15:06,606 --> 00:15:10,443
That's when I just broke down
and started crying.
187
00:15:13,646 --> 00:15:15,949
SMITH: Leland's ears were fine.
188
00:15:15,983 --> 00:15:17,817
That's not where
the problem was.
189
00:15:17,850 --> 00:15:20,954
Because you don't just
hear with your ears,
190
00:15:20,988 --> 00:15:23,790
you also hear with your brain.
191
00:15:23,823 --> 00:15:26,793
It's the same for
all the senses,
192
00:15:26,826 --> 00:15:30,964
they link our brains
to the outside world.
193
00:15:30,998 --> 00:15:35,935
And over hundreds of generations
they evolve to suit that world,
194
00:15:35,969 --> 00:15:38,605
no matter how harsh it is.
195
00:16:04,497 --> 00:16:08,735
SMITH: Hunters have lived here
for thousands of years.
196
00:16:13,973 --> 00:16:17,110
But to survive, they borrow
the senses of a creature
197
00:16:17,144 --> 00:16:19,846
that's been here even longer.
198
00:16:29,156 --> 00:16:36,063
(music)
199
00:16:36,096 --> 00:16:43,002
(music)
200
00:16:43,036 --> 00:16:48,341
(music)
201
00:16:53,513 --> 00:16:59,919
(music)
202
00:16:59,952 --> 00:17:02,989
(music)
203
00:17:03,022 --> 00:17:09,829
(music)
204
00:17:09,862 --> 00:17:16,736
(music)
205
00:17:25,312 --> 00:17:26,646
(horse snorts)
206
00:17:33,086 --> 00:17:39,959
(music)
207
00:17:39,992 --> 00:17:46,433
(music)
208
00:17:50,803 --> 00:17:52,071
(laughs)
209
00:17:52,105 --> 00:17:57,810
(music)
210
00:17:57,844 --> 00:18:02,782
SMITH: The eagle is like
a weaponized telescope.
211
00:18:02,815 --> 00:18:06,719
It can see a fox
up to two miles away.
212
00:18:06,753 --> 00:18:12,625
Out here, that's a crucial tool
in the fight for survival.
213
00:18:13,993 --> 00:18:15,162
(eagle chirps)
214
00:18:18,498 --> 00:18:19,766
(yells)
215
00:18:22,034 --> 00:18:25,838
(yelling)
216
00:18:25,872 --> 00:18:32,812
(music)
217
00:18:32,845 --> 00:18:38,985
(music)
218
00:18:39,018 --> 00:18:45,024
(music)
219
00:18:45,057 --> 00:18:51,998
(music)
220
00:18:52,031 --> 00:18:58,705
(music)
221
00:18:58,738 --> 00:19:01,140
(chirping)
222
00:19:01,174 --> 00:19:03,710
(yelling)
223
00:19:03,743 --> 00:19:05,812
(music)
224
00:19:05,845 --> 00:19:12,552
(music)
225
00:19:12,585 --> 00:19:14,787
SMITH: But to see like an eagle,
226
00:19:14,821 --> 00:19:17,790
you need more than eagle eyes;
227
00:19:17,824 --> 00:19:20,026
you need an eagle brain.
228
00:19:21,761 --> 00:19:23,963
(squawking)
229
00:19:23,996 --> 00:19:28,201
MELVIN: Eyes deliver masses of
data about the world around us,
230
00:19:28,235 --> 00:19:30,803
and all that lifesaving data
231
00:19:30,837 --> 00:19:35,041
needed something powerful
to make sense of it.
232
00:19:35,074 --> 00:19:38,545
Simply put,
if you're an animal with eyes,
233
00:19:38,578 --> 00:19:43,049
you're gonna need a bigger brain
than a sea squirt.
234
00:19:43,082 --> 00:19:45,718
Eyes were a real game changer.
235
00:19:48,020 --> 00:19:50,690
But it's not just the eyes.
236
00:19:52,759 --> 00:19:55,995
Creatures had to develop
an array of senses
237
00:19:56,028 --> 00:19:58,164
that are each calibrated to deal
238
00:19:58,197 --> 00:20:01,868
with the ever-changing
environment of Planet Earth.
239
00:20:03,970 --> 00:20:06,005
Not just barren desserts,
240
00:20:06,038 --> 00:20:08,708
but these very dense jungles,
241
00:20:08,741 --> 00:20:12,011
teeming ocean reefs,
242
00:20:12,044 --> 00:20:14,647
and even icy Arctic waste.
243
00:20:16,483 --> 00:20:20,086
The planet's varied landscapes
played a significant role
244
00:20:20,119 --> 00:20:22,655
in how animals sense.
245
00:20:25,758 --> 00:20:30,129
SMITH: What goes for them,
goes for us.
246
00:20:30,162 --> 00:20:33,733
The planet shaped
our senses, too.
247
00:20:35,735 --> 00:20:38,438
It's something
you might not notice
248
00:20:38,471 --> 00:20:40,573
unless you leave the planet.
249
00:20:44,611 --> 00:20:46,145
MIKE MASSIMINO:
Our senses have evolved
250
00:20:46,178 --> 00:20:49,982
to operate on Planet Earth.
251
00:20:50,016 --> 00:20:51,818
MAE JEMISON:
When you're up in space,
252
00:20:51,851 --> 00:20:54,954
the inner ear isn't registering
an up and down.
253
00:20:57,690 --> 00:20:59,826
MELVIN: So, your sense
of orientation
254
00:20:59,859 --> 00:21:01,694
only comes from your eyes.
255
00:21:03,696 --> 00:21:04,664
MASSIMINO:
You know that weird feeling
256
00:21:04,697 --> 00:21:05,832
in the pit of your stomach,
257
00:21:05,865 --> 00:21:08,635
when you go over the top
of a rollercoaster?
258
00:21:10,837 --> 00:21:13,540
I was basically in that moment
for an entire day.
259
00:21:16,175 --> 00:21:17,844
STOTT: We're Earthlings.
260
00:21:17,877 --> 00:21:21,113
That's just who we are.
261
00:21:21,147 --> 00:21:23,950
MELVIN: The evolution of the
senses in the primitive brain
262
00:21:23,983 --> 00:21:27,820
have allowed living creatures
to interact with our planet
263
00:21:27,854 --> 00:21:29,989
in a way like never before.
264
00:21:30,022 --> 00:21:31,958
But looking at our planet
from space,
265
00:21:31,991 --> 00:21:37,964
you can see it's not just
varied, it's dynamic.
266
00:21:37,997 --> 00:21:39,532
(thunder)
267
00:21:44,003 --> 00:21:47,006
SMITH: Sometimes,
the environment changes quickly,
268
00:21:47,039 --> 00:21:51,511
and when that happens, you have
to be just as fast to adapt.
269
00:21:51,544 --> 00:21:54,614
Like when the sea level
rises without warning,
270
00:21:54,647 --> 00:21:58,117
and now, you're
an island castaway.
271
00:21:58,150 --> 00:22:04,657
(music)
272
00:22:04,691 --> 00:22:10,897
(music)
273
00:22:10,930 --> 00:22:13,900
Macaques are great
with their hands.
274
00:22:13,933 --> 00:22:18,671
They peel fruit, climb trees,
and do each other's hair.
275
00:22:21,173 --> 00:22:26,045
But on these islands, they do
something no other macaques do.
276
00:22:26,078 --> 00:22:32,051
(music)
277
00:22:32,084 --> 00:22:35,087
(music)
278
00:22:35,121 --> 00:22:40,359
(music)
279
00:22:40,393 --> 00:22:47,333
(music)
280
00:22:47,366 --> 00:22:54,240
(music)
281
00:22:54,273 --> 00:23:01,213
(music)
282
00:23:01,247 --> 00:23:07,954
(music)
283
00:23:07,987 --> 00:23:11,824
They use rocks as tools
to shuck oysters.
284
00:23:14,494 --> 00:23:16,729
Macaques don't
normally eat them,
285
00:23:16,763 --> 00:23:19,632
but when they were stranded
by the rising sea,
286
00:23:19,666 --> 00:23:22,669
they needed new ways
to get a meal.
287
00:23:24,971 --> 00:23:26,973
They weren't born
with this skill;
288
00:23:27,006 --> 00:23:30,076
a smart monkey
had to work it out.
289
00:23:30,109 --> 00:23:32,111
(music)
290
00:23:32,144 --> 00:23:37,717
(music)
291
00:23:37,750 --> 00:23:41,454
This is something only
complex brains can do--
292
00:23:41,488 --> 00:23:43,956
not just sense and react,
293
00:23:43,990 --> 00:23:46,626
but learn,
294
00:23:46,659 --> 00:23:49,662
adapt and problem solve.
295
00:23:53,132 --> 00:23:57,804
But just because a macaque
can learn to shuck oysters
296
00:23:57,837 --> 00:24:01,340
doesn't mean it's gonna open
a seafood restaurant.
297
00:24:03,676 --> 00:24:06,746
Only a human would make
that mental leap.
298
00:24:06,779 --> 00:24:09,516
So, how come we're so different?
299
00:24:19,859 --> 00:24:23,796
SMITH: Monkeys were the first
primates in space,
300
00:24:23,830 --> 00:24:27,634
but it wasn't exactly
their idea.
301
00:24:27,667 --> 00:24:30,169
In fact, they were
probably against it.
302
00:24:30,202 --> 00:24:34,140
So, how come we're the apes
with the big ideas?
303
00:24:34,173 --> 00:24:37,877
Well, it's a long story.
304
00:24:37,910 --> 00:24:40,647
A story about something
that may not exist
305
00:24:40,680 --> 00:24:43,816
anywhere else
in the solar system,
306
00:24:43,850 --> 00:24:45,585
maybe the universe.
307
00:24:48,855 --> 00:24:51,490
Fire.
308
00:24:51,524 --> 00:24:53,926
(rooster crows)
309
00:25:08,240 --> 00:25:15,181
(music)
310
00:25:15,214 --> 00:25:19,686
(music)
311
00:25:31,698 --> 00:25:35,602
SMITH: The Himba people have
kept this same fire burning
312
00:25:35,635 --> 00:25:37,704
for generations.
313
00:26:05,798 --> 00:26:09,769
SMITH: As far as we know,
this planet is the only one
314
00:26:09,802 --> 00:26:14,607
with the right conditions
for fire to burn.
315
00:26:14,641 --> 00:26:19,746
But there's one thing that fire
gives us above all else.
316
00:26:45,004 --> 00:26:48,007
SMITH: But cooking food
does something
317
00:26:48,040 --> 00:26:53,780
that's way more important
than just making it tasty.
318
00:26:53,813 --> 00:26:58,484
MELVIN: Woo! We got fire,
are we ready for food?
319
00:26:58,517 --> 00:27:03,856
We as humans have these
power-hungry brains.
320
00:27:03,890 --> 00:27:06,092
A big chunk of our body's energy
321
00:27:06,125 --> 00:27:08,527
has to be used
to keep them running.
322
00:27:08,560 --> 00:27:10,196
Turn, baby, turn.
323
00:27:10,229 --> 00:27:12,865
By cooking, we're actually
breaking down
324
00:27:12,899 --> 00:27:15,534
the cell walls of the food
325
00:27:15,567 --> 00:27:18,971
that releases so many more
nutrients and calories,
326
00:27:19,005 --> 00:27:20,807
to help fuel our big brains.
327
00:27:24,576 --> 00:27:27,146
One of the key moments
in the history of our species
328
00:27:27,179 --> 00:27:30,817
was when our ancestors
harnessed fire.
329
00:27:30,850 --> 00:27:32,819
Alright, get your plates.
330
00:27:32,852 --> 00:27:36,522
The theory goes,
cooking let us get more energy
331
00:27:36,555 --> 00:27:38,991
out of every bite of food.
332
00:27:39,025 --> 00:27:42,561
So we spent less time
feeding our brain
333
00:27:42,594 --> 00:27:44,864
and more time using it.
334
00:27:48,901 --> 00:27:54,140
SMITH: Try going a day
that isn't touched by fire.
335
00:27:54,173 --> 00:27:57,810
You couldn't imagine
life without it.
336
00:27:57,844 --> 00:27:59,879
But a brain that
could harness fire
337
00:27:59,912 --> 00:28:01,748
may not have evolved
in the first place
338
00:28:01,781 --> 00:28:07,086
if it wasn't for
a force so powerful,
339
00:28:07,119 --> 00:28:10,356
it made the highest
mountains on Earth.
340
00:28:16,863 --> 00:28:21,834
(monks chanting)
341
00:28:21,868 --> 00:28:27,740
(monks chanting)
342
00:28:33,913 --> 00:28:35,915
(music)
343
00:28:35,948 --> 00:28:41,954
(music)
344
00:28:41,988 --> 00:28:48,928
(music)
345
00:28:48,961 --> 00:28:55,835
(music)
346
00:29:46,618 --> 00:29:49,088
SMITH: The fossils tell us
that these mountains,
347
00:29:49,121 --> 00:29:53,960
once at the bottom of the sea,
were forced high into the sky.
348
00:29:57,997 --> 00:29:58,965
LINENGER: When you're in orbit,
349
00:29:58,998 --> 00:30:01,800
as you come over
the Himalaya Mountains,
350
00:30:01,834 --> 00:30:05,972
you almost feel like you need to
fire the thrusters a little bit.
351
00:30:06,005 --> 00:30:08,140
You can tell where
that subcontinent
352
00:30:08,174 --> 00:30:10,809
just jammed into
the Asian continent
353
00:30:10,843 --> 00:30:14,046
and thrust those mountains up.
354
00:30:14,080 --> 00:30:17,016
CHRIS HADFIELD: This collision
between the smooth flatness
355
00:30:17,049 --> 00:30:20,819
of India and these rugged,
crumpled mountains,
356
00:30:20,853 --> 00:30:24,423
it's like watching a super
slow-motion train wreck.
357
00:30:26,725 --> 00:30:28,494
MASSIMINO:
The further you get away,
358
00:30:28,527 --> 00:30:30,829
you can kind of see
these overarching themes
359
00:30:30,863 --> 00:30:32,899
to the way our planet is formed.
360
00:30:38,670 --> 00:30:40,973
MELVIN: It was forces like these
that would transform
361
00:30:41,007 --> 00:30:43,142
one particular corner
of our rock
362
00:30:43,175 --> 00:30:46,112
into the cradle of humanity.
363
00:30:50,016 --> 00:30:53,052
The Great Rift Valley
in East Africa
364
00:30:53,085 --> 00:30:58,724
was once a lush green forest,
a paradise for apes.
365
00:30:58,757 --> 00:31:00,826
(music)
366
00:31:00,859 --> 00:31:06,832
(music)
367
00:31:06,865 --> 00:31:10,569
But the Earth's crust shifted,
mountains rose,
368
00:31:10,602 --> 00:31:14,941
and the climate changed, making
it a much tougher place to live.
369
00:31:14,974 --> 00:31:20,612
(music)
370
00:31:20,646 --> 00:31:24,716
It's hard to really know exactly
how our ancestors adapted
371
00:31:24,750 --> 00:31:26,885
over millions of years.
372
00:31:29,821 --> 00:31:31,857
The changes may have pushed apes
to do things
373
00:31:31,890 --> 00:31:34,826
like innovate the tools.
374
00:31:36,963 --> 00:31:39,498
Or walk on two legs.
375
00:31:41,733 --> 00:31:44,770
And even harness fire.
376
00:31:44,803 --> 00:31:49,976
Whatever it was, we came out
the other side as early humans,
377
00:31:50,009 --> 00:31:51,677
with bigger brains.
378
00:31:54,780 --> 00:31:57,083
SMITH: We took off
across the planet,
379
00:31:57,116 --> 00:32:02,654
and there was one uniquely human
skill we brought with us.
380
00:32:02,688 --> 00:32:05,557
Here I am, talking to you,
381
00:32:05,591 --> 00:32:09,495
and some of you
are even listening.
382
00:32:09,528 --> 00:32:12,798
What you're hearing is probably
the most powerful tool
383
00:32:12,831 --> 00:32:15,134
we've ever mastered.
384
00:32:15,167 --> 00:32:18,971
So, how do you get a brain that
can tell a damn good story?
385
00:32:25,644 --> 00:32:32,818
(people speaking
different languages)
386
00:32:32,851 --> 00:32:34,653
SMITH: We speak.
387
00:32:34,686 --> 00:32:40,993
(all talking)
388
00:32:41,027 --> 00:32:45,464
SMITH: We link signs and sounds
to thoughts and things,
389
00:32:45,497 --> 00:32:49,801
in countless ways, creating
almost infinite meanings.
390
00:32:49,835 --> 00:32:53,839
That takes a lot of brain power.
391
00:32:53,872 --> 00:33:00,712
(music)
392
00:33:07,519 --> 00:33:10,856
JULIE MISAKI: Moving to
Hong Kong has been amazing.
393
00:33:13,892 --> 00:33:15,861
I'm originally from Japan,
394
00:33:15,894 --> 00:33:19,098
but I've lived in Hong Kong
for six years now.
395
00:33:23,935 --> 00:33:26,905
But it has its challenges.
396
00:33:28,940 --> 00:33:32,010
Even just buying dinner
can get complicated.
397
00:33:35,547 --> 00:33:38,684
A lot of us foreigners
try to learn Chinese,
398
00:33:38,717 --> 00:33:41,587
but it's not always easy.
399
00:33:43,522 --> 00:33:47,059
One word can actually
have many meanings,
400
00:33:47,093 --> 00:33:49,528
depending on the tone you use.
401
00:33:51,063 --> 00:33:57,669
For example, if I say xiao,
it means burn,
402
00:33:57,703 --> 00:34:01,873
or xiao, it means little,
403
00:34:01,907 --> 00:34:05,611
or xiao, it means laugh.
404
00:34:09,481 --> 00:34:14,786
Use the wrong tone,
you could be in big trouble.
405
00:34:14,820 --> 00:34:16,588
MELVIN: It's only
us human beings
406
00:34:16,622 --> 00:34:19,958
that have developed
complex language.
407
00:34:19,991 --> 00:34:22,128
Unlike many other languages,
408
00:34:22,161 --> 00:34:25,131
Chinese uses the musical areas
of the brain
409
00:34:25,164 --> 00:34:29,801
to extract meaning
from all those tones.
410
00:34:29,835 --> 00:34:34,473
And that takes a lot
of processing power.
411
00:34:34,506 --> 00:34:37,776
But the really big question is
412
00:34:37,809 --> 00:34:42,948
why we have any language at all.
413
00:34:42,981 --> 00:34:46,685
It's partly due to
the size of our big brains.
414
00:34:50,489 --> 00:34:54,893
But there could be
another factor at play.
415
00:34:54,926 --> 00:35:00,065
One theory is that it was
something really tiny.
416
00:35:00,098 --> 00:35:04,102
There's a version of a gene,
called FOXP2,
417
00:35:04,136 --> 00:35:07,005
that only us humans have.
418
00:35:07,038 --> 00:35:10,542
Take it away, and
you'll struggle to talk.
419
00:35:12,178 --> 00:35:15,647
No one knows how we've
got this mutation.
420
00:35:17,683 --> 00:35:20,852
(speaking Japanese)
421
00:35:20,886 --> 00:35:22,688
But we do know...
422
00:35:22,721 --> 00:35:25,157
(speaking Japanese)
423
00:35:25,191 --> 00:35:27,693
...it gave us
more precise control
424
00:35:27,726 --> 00:35:31,997
over our mouth and
our tongue muscles.
425
00:35:32,030 --> 00:35:36,835
And that let us make
more sophisticated sounds,
426
00:35:36,868 --> 00:35:39,838
helping us turn
thoughts into words.
427
00:35:44,009 --> 00:35:46,545
SMITH: Small genetic twists
turned us
428
00:35:46,578 --> 00:35:48,814
from a bunch of folks who grunt
429
00:35:48,847 --> 00:35:53,485
to a species that can tell
xiao from xiao,
430
00:35:53,519 --> 00:35:55,987
from xiao.
431
00:35:56,021 --> 00:36:00,158
Sharing ideas,
communicating them,
432
00:36:00,192 --> 00:36:05,564
lets us do things that alone
would be impossible.
433
00:36:05,597 --> 00:36:09,235
Something pioneers
know full well.
434
00:36:09,268 --> 00:36:12,571
(roaring)
435
00:36:12,604 --> 00:36:18,810
(music)
436
00:36:18,844 --> 00:36:21,079
ROCKY ROBINSON:
Okay, let's do it.
437
00:36:21,112 --> 00:36:22,748
I'm getting all kinds--
I've wiped it off,
438
00:36:22,781 --> 00:36:24,916
but I have all kinds
of salt on me.
439
00:36:24,950 --> 00:36:26,752
My shield got covered in salt.
440
00:36:26,785 --> 00:36:29,388
MAN: Turn the water pump off.
441
00:36:29,421 --> 00:36:30,756
ROBINSON: We're here in Bolivia
442
00:36:30,789 --> 00:36:35,160
trying to break the motorcycle
world land speed record.
443
00:36:35,193 --> 00:36:36,762
We probably don't have
a better opportunity
444
00:36:36,795 --> 00:36:40,899
than we have right now to see
just how fast this bike will go.
445
00:36:40,932 --> 00:36:42,934
(music)
446
00:36:42,968 --> 00:36:48,607
(music)
447
00:36:48,640 --> 00:36:51,109
This is a huge team effort.
448
00:36:51,142 --> 00:36:54,546
We communicate a lot,
the team and I.
449
00:36:54,580 --> 00:36:56,948
Communication is
a huge advantage.
450
00:36:59,885 --> 00:37:01,119
It takes so many people
451
00:37:01,152 --> 00:37:04,022
to come up with a machine
of this caliber.
452
00:37:04,055 --> 00:37:08,694
(engine revving)
453
00:37:08,727 --> 00:37:10,796
You have all these people doing
all this stuff for you,
454
00:37:10,829 --> 00:37:12,964
but once that canopy closes...
455
00:37:12,998 --> 00:37:14,099
MAN: You ready?
456
00:37:14,132 --> 00:37:15,634
ROBINSON: You're all alone.
457
00:37:17,836 --> 00:37:20,906
MAN: 45, hit it, Rocky!
458
00:37:32,818 --> 00:37:35,120
MAN ON RADIO: Full speed, 333.9.
459
00:37:35,153 --> 00:37:36,755
MAN ON RADIO: Roger, six.
460
00:37:40,859 --> 00:37:43,128
ROBINSON: Whoa, whoa, whoa!
461
00:37:43,161 --> 00:37:45,964
There's something wrong
with the motor.
462
00:37:45,997 --> 00:37:48,667
MAN ON RADIO: He's coming
to a...he's slowing down.
463
00:37:50,836 --> 00:37:53,004
Everything okay down there?
464
00:37:53,038 --> 00:37:55,607
MAN ON RADIO: Seems okay.
465
00:37:55,641 --> 00:37:56,608
ROBINSON: It is going
really strong,
466
00:37:56,642 --> 00:37:58,644
and it's, whoa, whoa, whoa.
467
00:37:58,677 --> 00:37:59,645
MAN: Main off?
468
00:37:59,678 --> 00:38:00,946
ROBINSON: Yeah.
MAN: Okay.
469
00:38:00,979 --> 00:38:03,815
ROBINSON: Got up to right around
378 miles an hour,
470
00:38:03,849 --> 00:38:06,952
and then the turbo coupler
came off.
471
00:38:08,787 --> 00:38:10,689
It's frustrating.
472
00:38:10,722 --> 00:38:12,123
It's a huge team effort,
473
00:38:12,157 --> 00:38:15,160
and, you know, we're all
trying to reach our goal.
474
00:38:15,193 --> 00:38:18,497
Probably 95% of the time
there is something going wrong.
475
00:38:18,530 --> 00:38:21,533
That's why records last so long.
476
00:38:21,567 --> 00:38:22,834
Everything about
land speed racing
477
00:38:22,868 --> 00:38:26,872
is learning what's new
and how to improve things.
478
00:38:26,905 --> 00:38:29,708
We learn a lot, and I think
we can put that to good use
479
00:38:29,741 --> 00:38:31,009
in the future.
480
00:38:33,812 --> 00:38:35,781
SMITH: I'm with Rocky on this.
481
00:38:35,814 --> 00:38:39,718
You get knocked down,
you get back up again.
482
00:38:39,751 --> 00:38:44,423
Communicating helps you face
failure without fear.
483
00:38:47,559 --> 00:38:49,961
But our brains adapt.
484
00:38:49,995 --> 00:38:52,964
So if we lose the ability
to communicate,
485
00:38:52,998 --> 00:38:57,736
our brain might find
a work-around.
486
00:38:57,769 --> 00:38:59,871
It's flexible.
487
00:38:59,905 --> 00:39:01,840
Talk to Leland about it.
488
00:39:04,776 --> 00:39:05,844
MELVIN: During the time
of recovery
489
00:39:05,877 --> 00:39:08,814
from my hearing accident,
490
00:39:08,847 --> 00:39:13,218
there was a point when I could
feel my brain rewiring itself
491
00:39:13,251 --> 00:39:14,853
to hear again.
492
00:39:16,855 --> 00:39:19,925
The brain over time
can make adjustments
493
00:39:19,958 --> 00:39:24,663
to compensate for
losses or changes.
494
00:39:24,696 --> 00:39:27,833
And I think that's
what happened to me.
495
00:39:27,866 --> 00:39:29,601
My hearing started coming back
496
00:39:29,635 --> 00:39:31,903
about three weeks
after my accident.
497
00:39:33,772 --> 00:39:39,778
But it took two more years
for me to recover properly.
498
00:39:39,811 --> 00:39:42,914
Then finally, the chief
medical officer for NASA
499
00:39:42,948 --> 00:39:47,052
pulled out a piece of paper
500
00:39:47,085 --> 00:39:50,489
that said, 'You are now cleared
to fly in space.'
501
00:39:53,992 --> 00:39:58,764
That was one of the most
incredible days of my life.
502
00:39:58,797 --> 00:40:01,132
I never took my brain
for granted again.
503
00:40:01,166 --> 00:40:05,070
(crowd cheering)
504
00:40:05,103 --> 00:40:06,938
SMITH: With that flexible brain,
505
00:40:06,972 --> 00:40:11,943
we learn, adapt,
and problem solve.
506
00:40:11,977 --> 00:40:15,947
Our brains give us language,
507
00:40:15,981 --> 00:40:20,719
allowing us to share
those lessons with others.
508
00:40:20,752 --> 00:40:25,657
And writing lets us pass on
that knowledge through time.
509
00:40:29,160 --> 00:40:30,962
LINENGER:
All that human brain power,
510
00:40:30,996 --> 00:40:34,566
all that knowledge
through written textbooks,
511
00:40:34,600 --> 00:40:37,736
through calculations,
through mathematics.
512
00:40:37,769 --> 00:40:40,472
HOFFMAN: That just led
to a huge explosion
513
00:40:40,506 --> 00:40:43,041
in the development
of civilization.
514
00:40:45,343 --> 00:40:46,812
WHITSON:
We can get a lot smarter,
515
00:40:46,845 --> 00:40:52,818
because we can learn a lot more
from the previous generations.
516
00:40:52,851 --> 00:40:56,922
SMITH: Humanity is linked
together by a network of minds
517
00:40:56,955 --> 00:41:00,826
that spans time and space.
518
00:41:00,859 --> 00:41:05,797
And that's helped us create
things of dazzling complexity.
519
00:41:08,033 --> 00:41:13,539
The most complex one we've ever
made is floating above us.
520
00:41:22,247 --> 00:41:23,515
MAN ON RADIO:
Ignition sequence start.
521
00:41:23,549 --> 00:41:27,686
Five, four, three, two, one.
522
00:41:32,023 --> 00:41:35,894
MELVIN: You're lifting off
of the planet.
523
00:41:35,927 --> 00:41:37,896
Feeling 3 Gs on your chest
524
00:41:37,929 --> 00:41:40,999
as you're being propelled
to the cosmos.
525
00:41:41,032 --> 00:41:43,101
It is one heck of a ride.
526
00:41:48,173 --> 00:41:51,476
MELVIN: After losing
the sense of hearing,
527
00:41:51,509 --> 00:41:54,479
it took so many years for me
to get to the launchpad,
528
00:41:54,512 --> 00:41:58,717
but it just took a few minutes
to get to orbit.
529
00:41:58,750 --> 00:42:01,853
MAN ON RADIO:
Good morning, Houston.
530
00:42:01,887 --> 00:42:04,489
MELVIN: We got to space,
I saw the planet.
531
00:42:04,522 --> 00:42:06,625
It just blows your mind.
532
00:42:09,027 --> 00:42:13,031
This burst of color.
533
00:42:13,064 --> 00:42:15,867
I've never seen colors
that vibrant before.
534
00:42:19,738 --> 00:42:23,274
And I almost had to, like, smack
myself to get back to work.
535
00:42:23,308 --> 00:42:29,014
(music)
536
00:42:29,047 --> 00:42:30,548
MAN ON RADIO:
If you could get the other...
537
00:42:30,582 --> 00:42:33,652
the expedition four crew,
that we have them in sight.
538
00:42:36,755 --> 00:42:41,459
MELVIN: And then I saw this
little dot out on the horizon.
539
00:42:41,492 --> 00:42:44,630
And we get closer
and closer and closer.
540
00:42:44,663 --> 00:42:51,136
(music)
541
00:42:51,169 --> 00:42:54,740
The first time I saw the
space station flying overhead,
542
00:42:54,773 --> 00:42:59,911
I never knew how complex
a vehicle it was.
543
00:42:59,945 --> 00:43:04,783
(music)
544
00:43:04,816 --> 00:43:07,986
You know, you could see
the intricate design
545
00:43:08,019 --> 00:43:10,922
in these modules,
all these things
546
00:43:10,956 --> 00:43:14,960
that were envisioned
by the human brain.
547
00:43:14,993 --> 00:43:16,762
(music)
548
00:43:16,795 --> 00:43:23,835
(music)
549
00:43:23,869 --> 00:43:25,804
WHITSON: So, you know,
when you approach it,
550
00:43:25,837 --> 00:43:28,139
it's just so beautiful.
551
00:43:28,173 --> 00:43:31,677
It's an amazing, amazing
engineering marvel.
552
00:43:33,812 --> 00:43:35,847
HOFFMAN: There's no question
that the space station
553
00:43:35,881 --> 00:43:39,818
is the greatest international
scientific project
554
00:43:39,851 --> 00:43:42,821
that's ever been undertaken.
555
00:43:42,854 --> 00:43:47,125
LINENGER: It's like, wow,
this thing is awesome.
556
00:43:47,158 --> 00:43:48,927
And I'm gonna get
to live on that thing
557
00:43:48,960 --> 00:43:50,662
for four or five months.
558
00:43:50,696 --> 00:43:56,802
(music)
559
00:43:56,835 --> 00:43:57,803
MAN ON RADIO: Coming in now
and carrying the camera,
560
00:43:57,836 --> 00:44:01,639
mission specialist
Leland Melvin.
561
00:44:01,673 --> 00:44:02,640
MAN: How you doing?
562
00:44:02,674 --> 00:44:03,775
MAN: Bull in a china shop, man.
563
00:44:03,809 --> 00:44:06,845
(laughs)
564
00:44:12,851 --> 00:44:14,953
MELVIN:
Climbing this hill to space
565
00:44:14,986 --> 00:44:18,957
was one of the hardest things
I've ever done.
566
00:44:18,990 --> 00:44:21,559
I never imagined myself
going deaf,
567
00:44:21,592 --> 00:44:22,961
I never imagined coming back
568
00:44:22,994 --> 00:44:25,731
and getting this opportunity
after that accident.
569
00:44:25,764 --> 00:44:31,803
(music)
570
00:44:31,837 --> 00:44:37,008
And it's really a similar story
for all of humankind.
571
00:44:37,042 --> 00:44:39,878
Everything we've achieved
as a species
572
00:44:39,911 --> 00:44:43,749
is the product of
a lucky chain of accidents.
573
00:44:48,119 --> 00:44:52,690
SMITH: To get here, we needed
a planet to congeal out of dust.
574
00:44:54,893 --> 00:45:00,431
In the right place for life
to form and mold our world,
575
00:45:00,465 --> 00:45:04,369
allowing us to breathe
and grow complex.
576
00:45:07,205 --> 00:45:11,777
We needed to be shielded
from our sun,
577
00:45:11,810 --> 00:45:14,913
gifted with a moon,
578
00:45:14,946 --> 00:45:17,548
and granted seasons.
579
00:45:17,582 --> 00:45:19,918
We needed just enough
bombardments
580
00:45:19,951 --> 00:45:21,452
and near-annihilations
581
00:45:21,486 --> 00:45:23,454
to let life meander
582
00:45:23,488 --> 00:45:25,556
through its twists and turns
583
00:45:25,590 --> 00:45:28,126
and evolve a species
584
00:45:28,159 --> 00:45:33,131
with a brain as complex
as yours and mine.
585
00:45:33,164 --> 00:45:34,599
(baby cries)
586
00:45:34,632 --> 00:45:36,601
(music)
587
00:45:36,634 --> 00:45:41,807
(music)
588
00:45:41,840 --> 00:45:43,775
MELVIN: When I was
on the space station,
589
00:45:43,809 --> 00:45:47,745
looking back at the planet,
590
00:45:47,779 --> 00:45:52,951
it gave me
a profound appreciation
591
00:45:52,984 --> 00:45:55,586
in what we take for granted.
592
00:45:58,656 --> 00:46:02,928
Humans are a wonderful,
extraordinary oddity.
593
00:46:02,961 --> 00:46:07,899
(music)
594
00:46:07,933 --> 00:46:10,168
SMITH: Good job, man,
great game.
595
00:46:10,201 --> 00:46:13,004
With this blob of Jell-O,
596
00:46:13,038 --> 00:46:17,642
these 86 billion neurons,
597
00:46:17,675 --> 00:46:19,978
we've left the planet
598
00:46:20,011 --> 00:46:23,748
and looked far, far out
into the universe,
599
00:46:23,781 --> 00:46:28,519
trying to unravel the mysteries
of the cosmos.
600
00:46:28,553 --> 00:46:31,656
But no matter
how far out we look,
601
00:46:31,689 --> 00:46:34,592
the most far-out thing
we've ever found
602
00:46:34,625 --> 00:46:36,794
is right between our ears.
603
00:46:36,828 --> 00:46:43,634
(music)
604
00:46:43,668 --> 00:46:50,175
(music)
605
00:46:50,208 --> 00:46:52,177
Next time...
606
00:46:52,210 --> 00:46:56,647
What does it feel like when
you finally come back to Earth?
607
00:46:56,681 --> 00:46:59,517
Is there really
no place like home?
