18
00:01:37,900 --> 00:01:40,740
Wenjie, this is an official decision.

19
00:01:40,740 --> 00:01:44,100
From this day onwards, you'll be working
in the Monitoring Department.

20
00:01:44,100 --> 00:01:48,260
Now I'll explain the work
of the Monitoring Department to you.

21
00:01:48,260 --> 00:01:53,460
Simply put, the goal is to keep an eye

22
00:01:53,980 --> 00:01:56,220
on all enemy activities in space,

23
00:01:56,220 --> 00:02:00,100
including intercepting communications

24
00:02:00,100 --> 00:02:03,580
between enemy space vessels and the ground,
and between the space vessels themselves,

25
00:02:03,580 --> 00:02:05,900
track the orbits
of enemy space vessels,

26
00:02:05,900 --> 00:02:08,820
collaborate with our telemetry
and tracking centers,

27
00:02:08,820 --> 00:02:11,260
and provide data
for Red Coast's combat systems.

28
00:02:11,260 --> 00:02:14,940
In other words,
the eyes of Red Coast are here.

29
00:02:14,940 --> 00:02:17,660
Political Commissar Lei,

30
00:02:17,660 --> 00:02:23,980
I think you should reconsider
whether it's necessary to tell her this.

31
00:02:28,660 --> 00:02:34,140
Political Commissar Lei,
if it's too sensitive, then...

32
00:02:34,140 --> 00:02:36,340
No, Wenjie.

33
00:02:37,500 --> 00:02:42,380
Weining, like I said, work must be done.

34
00:02:42,380 --> 00:02:48,660
She needs all the information
in order to do her job.

35
00:02:48,860 --> 00:02:49,780
Fine.

36
00:02:49,780 --> 00:02:51,340
I'll report this to the high-ups.

37
00:02:51,340 --> 00:02:52,420
Sure.

38
00:02:52,420 --> 00:02:54,140
You have the right to do so.

39
00:02:54,140 --> 00:02:58,260
But I give you my word that
I'll take full responsibility for my action.

40
00:02:58,260 --> 00:02:59,700
Alright.

41
00:02:59,700 --> 00:03:02,820
I'll take your word for it.

42
00:03:10,100 --> 00:03:10,980
Don't mind him.

43
00:03:10,980 --> 00:03:12,380
That's just the way he is.

44
00:03:12,380 --> 00:03:15,220
He can be too cautious
to be openhanded at work.

45
00:03:15,220 --> 00:03:17,780
Wenjie, come here.

46
00:03:17,780 --> 00:03:20,380
Take a seat.

47
00:03:21,100 --> 00:03:23,580
Sit.

48
00:03:30,220 --> 00:03:34,660
Look, when we first brought you here,
the goal was simple.

49
00:03:34,660 --> 00:03:37,460
Red Coast's monitoring system
often had interference

50
00:03:37,460 --> 00:03:42,340
caused by electromagnetic radiation
from solar flares and sunspots.

51
00:03:42,340 --> 00:03:44,820
Then we came across your paper

52
00:03:44,820 --> 00:03:48,580
and believed that you were
an expert in solar activity.

53
00:03:48,580 --> 00:03:51,260
And your predictive model
was the most accurate.

54
00:03:51,260 --> 00:03:55,140
So we wanted to solicit your help
in solving this problem.

55
00:03:55,140 --> 00:03:58,700
After you came,
you demonstrated strong abilities,

56
00:03:58,700 --> 00:04:03,260
so I decided to entrust you
with more important work.

57
00:04:03,260 --> 00:04:07,140
You've worked in Transmission
for a while

58
00:04:07,140 --> 00:04:09,260
and gained an overview of Red Coast.

59
00:04:09,260 --> 00:04:11,220
Now that you're transferred,

60
00:04:11,220 --> 00:04:15,580
your assignment in Monitoring
will be discussed later.

61
00:04:15,580 --> 00:04:21,260
Of course, as you can see,
there's some resistance.

62
00:04:21,980 --> 00:04:25,140
But I trust you.

63
00:04:25,140 --> 00:04:30,620
Personally, I have faith in you.

64
00:04:30,620 --> 00:04:37,100
I hope you can keep up the good work
and earn the trust of the organization.

65
00:04:43,740 --> 00:04:48,500
Wenjie, honestly,

66
00:04:48,500 --> 00:04:52,740
I sincerely hope that someday,

67
00:04:54,820 --> 00:04:59,620
I'll be able to call you Comrade Ye.

68
00:05:05,660 --> 00:05:08,220
Don't let me down.

69
00:05:29,660 --> 00:05:33,020
Even though
Political Commissar Lei trusted me,

70
00:05:33,020 --> 00:05:36,460
my activities were severely restricted.

71
00:05:36,460 --> 00:05:42,820
I had access to the software
source code, but not the database.

72
00:05:42,820 --> 00:05:48,300
And I had to learn the software techniques
from scratch.

73
00:05:48,300 --> 00:05:52,940
That was far from being easy.

74
00:06:05,340 --> 00:06:07,940
(File Bag)
(According to the latest weather forecast,)

75
00:06:07,940 --> 00:06:10,820
(from 8:00 AM today
to 8:00 PM tomorrow,)

76
00:06:10,820 --> 00:06:15,980
(parts of the Northwest
will see light snow or sleet.)

77
00:06:15,980 --> 00:06:19,620
(The local high will be
9 degrees Celsius.)

78
00:06:19,620 --> 00:06:20,980
Report.

79
00:06:20,980 --> 00:06:23,580
Come in.

80
00:06:25,740 --> 00:06:28,380
Chief Engineer Yang,
after being deciphered by the computer,

81
00:06:28,380 --> 00:06:32,140
what we had received turned out to be
a few satellite photographs.

82
00:06:32,140 --> 00:06:34,180
GSD's Surveying and Mapping Bureau said

83
00:06:34,180 --> 00:06:36,780
they're images of
our important military targets,

84
00:06:36,780 --> 00:06:39,580
including the naval harbor at Qingdao
and several key factories

85
00:06:39,580 --> 00:06:43,340
of the Third Front program.

86
00:06:43,340 --> 00:06:45,380
Did we monitor their satellites?

87
00:06:45,380 --> 00:06:48,700
Analysis confirmed
that these images came from the KA-9

88
00:06:48,700 --> 00:06:51,460
Reconnaissance System of the West.

89
00:06:51,460 --> 00:06:54,340
The first KA-9 had just been launched.

90
00:06:54,340 --> 00:06:57,420
Although it mainly relied on recoverable
film capsules for intelligence gathering,

91
00:06:57,420 --> 00:06:59,300
it was also being used to test out

92
00:06:59,300 --> 00:07:01,900
the more advanced radio transmission
of digital images.

93
00:07:01,900 --> 00:07:04,700
As the...

94
00:07:07,700 --> 00:07:11,340
As the technology is undeveloped,
the satellite transmitted at a low frequency,

95
00:07:11,340 --> 00:07:17,060
which increased its range of reception
sufficiently for it to be intercepted by us.

96
00:07:17,260 --> 00:07:19,220
Abandon this target.

97
00:07:19,220 --> 00:07:20,900
Change the frequency.

98
00:07:20,900 --> 00:07:25,060
I'll let you know about the direction.

99
00:07:25,060 --> 00:07:29,180
We're having a rare opportunity to learn more
about the Western satellite reconnaissance system.

100
00:07:29,180 --> 00:07:30,820
Are you sure about letting it go?

101
00:07:30,820 --> 00:07:33,220
How many times do I have to tell you?

102
00:07:33,220 --> 00:07:37,500
Change the direction
and the frequency!

103
00:07:46,860 --> 00:07:49,660
Transmission has a machine down.

104
00:07:49,660 --> 00:07:52,740
Go and check it.

105
00:07:55,580 --> 00:07:58,100
Yes, sir.

106
00:08:08,900 --> 00:08:14,260
So, it was Yang Weining
who kept holding you back?

107
00:08:14,700 --> 00:08:20,260
He was acting weird,
always lashing out at me for no reason.

108
00:08:20,260 --> 00:08:22,100
But I didn't mind.

109
00:08:22,100 --> 00:08:29,020
What mattered to me
was those unexplainable matters at work.

110
00:08:29,020 --> 00:08:32,940
They made me realize
that Red Coast was

111
00:08:32,940 --> 00:08:37,020
far more complex than I had imagined.

112
00:08:53,580 --> 00:08:57,660
(The 299th transmission
of Red Coast Project is finished.)

113
00:08:57,660 --> 00:08:59,620
(Shutting down transmission system.)

114
00:08:59,620 --> 00:09:02,220
(Red Coast entering monitoring mode.)

115
00:09:02,220 --> 00:09:11,660
(Monitoring frequency range:
1,000 MHz to 40,000 MHz.)

116
00:09:11,660 --> 00:09:18,020
(Monitoring channels: 15,000.)

117
00:09:18,020 --> 00:09:23,060
(Key frequencies to monitor:
Hydrogen atom frequency at 1,420 MHz.)

118
00:09:23,060 --> 00:09:28,140
(Hydroxyl radical radiation frequency
at 1,667 MHz.)

119
00:09:28,140 --> 00:09:31,980
(Water molecule radiation frequency
at 22,000 MHz.)

120
00:09:31,980 --> 00:09:33,220
(Repeat.)

121
00:09:33,220 --> 00:09:39,260
(Key frequencies to monitor:
Hydrogen atom frequency at 1,420 MHz...)

122
00:09:39,260 --> 00:09:43,820
The designated frequencies
for the three transmissions

123
00:09:43,820 --> 00:09:48,300
were lower than microwave range
and couldn't result in

124
00:09:48,300 --> 00:09:50,980
any heating effect in the target.

125
00:09:50,980 --> 00:09:54,020
Both Yang Weining's strange attitude

126
00:09:54,020 --> 00:09:58,860
and those abnormal cases
said one thing.

127
00:09:58,860 --> 00:10:04,260
That is, the real purpose of Red Coast
was top-secret.

128
00:10:17,140 --> 00:10:18,460
(Calling Wang Miao End Call)

129
00:10:18,460 --> 00:10:20,860
(Chang)

130
00:10:26,420 --> 00:10:29,300
Chang, it's me.

131
00:10:29,300 --> 00:10:33,620
We're in Qijiatun.
I've checked with the village committee.

132
00:10:33,620 --> 00:10:34,940
(Red Coast File Bag)

133
00:10:34,940 --> 00:10:37,020
That red ginseng factory checks out.

134
00:10:37,020 --> 00:10:41,220
The locals can get paid
by working there.

135
00:10:41,220 --> 00:10:43,700
Where are we on declassifying the files?

136
00:10:43,700 --> 00:10:47,140
You've promised me. I need them today.

137
00:10:47,140 --> 00:10:49,140
I've got them.

138
00:10:49,140 --> 00:10:53,820
What's inside
is way beyond imagination.

139
00:10:53,820 --> 00:10:56,300
Don't keep me guessing, OK?

140
00:10:56,300 --> 00:10:59,180
What on earth is Red Coast for?

141
00:10:59,180 --> 00:11:05,180
Their research
is indeed the most confidential.

142
00:11:05,460 --> 00:11:09,340
(Troubleshooting
of Magnetic Core Memory is complete.)

143
00:11:09,340 --> 00:11:10,620
(Clear fault codes.)

144
00:11:10,620 --> 00:11:12,020
Hello?

145
00:11:12,020 --> 00:11:16,020
Ye Wenjie, come to my office now.

146
00:11:16,020 --> 00:11:18,260
Yes, sir.

147
00:11:18,260 --> 00:11:21,700
(A routine work meeting
will be held at 3:00 PM.)

148
00:11:21,700 --> 00:11:25,060
(Please be prepared.)

149
00:11:25,060 --> 00:11:30,740
(Department heads
are to attend on time.)

150
00:11:52,380 --> 00:11:54,820
Report.

151
00:11:54,820 --> 00:11:57,340
Come in.

152
00:12:08,740 --> 00:12:13,700
Ye Wenjie, come here.

153
00:12:18,500 --> 00:12:21,740
I assumed Political Commissar Lei

154
00:12:21,740 --> 00:12:25,020
was being punished for promoting me.

155
00:12:26,340 --> 00:12:28,900
I told myself that no matter what,

156
00:12:28,900 --> 00:12:32,900
I couldn't drag him down
even if I had to lie.

157
00:12:32,900 --> 00:12:36,540
(Ye Wenjie Experience)

158
00:12:46,940 --> 00:12:52,740
Ye Wenjie, first, let me be clear
that I disagree with all this.

159
00:12:52,740 --> 00:12:55,380
The decision was made
by Chief Engineer Yang

160
00:12:55,380 --> 00:12:58,660
after seeking the high-ups' permission.

161
00:12:58,660 --> 00:13:02,100
He alone will take all the consequences.

162
00:13:02,100 --> 00:13:08,300
To better utilize your skills,
he talked to the superiors repeatedly.

163
00:13:08,300 --> 00:13:13,820
Army Political Department
did their investigation, too.

164
00:13:13,820 --> 00:13:17,300
Now, we've been authorized
to disclose the true nature

165
00:13:17,300 --> 00:13:20,740
of the Red Coast Project to you.

166
00:13:29,500 --> 00:13:34,260
I hope you'll treasure this opportunity
and work hard to redeem your sins.

167
00:13:34,260 --> 00:13:37,060
From now on, you must behave
with the utmost propriety.

168
00:13:37,060 --> 00:13:39,740
Any transgression

169
00:13:40,060 --> 00:13:43,260
will receive the harshest punishment.

170
00:13:45,260 --> 00:13:48,260
Understood?

171
00:13:48,980 --> 00:13:51,100
Yes, sir.

172
00:13:51,100 --> 00:13:54,740
It wasn't until then that I realized

173
00:13:54,740 --> 00:13:59,260
everything Lei Zhicheng had told me
was a lie.

174
00:13:59,260 --> 00:14:03,500
Red Coast
was neither a powerful weapon

175
00:14:03,500 --> 00:14:07,780
nor a monitor on enemy space vessels.

176
00:14:07,780 --> 00:14:13,580
All his care, promotion, and protection
were all an act.

177
00:14:15,220 --> 00:14:21,300
That's why Yang Weining
tried to stop him.

178
00:14:24,980 --> 00:14:30,860
Yang Weining was a good man.

179
00:14:31,500 --> 00:14:35,740
When the leaders
doubted me for my background,

180
00:14:35,740 --> 00:14:39,900
he stood up for me.

181
00:14:40,220 --> 00:14:42,140
And it was also he

182
00:14:42,980 --> 00:14:48,580
who told me the truth about Red Coast.

183
00:14:50,100 --> 00:14:54,820
If you want to quit,
it's not too late now.

184
00:14:54,820 --> 00:14:57,740
I'll do it.

185
00:15:06,780 --> 00:15:08,780
Are you sure?

186
00:15:08,780 --> 00:15:15,500
Once you said yes, the last ray of hope
of leaving Radar Peak would be gone.

187
00:15:15,940 --> 00:15:22,260
You'd spend the rest of your life here.

188
00:15:25,140 --> 00:15:27,940
Yes, I'll do it.

189
00:15:41,900 --> 00:15:48,900
The truth was an incredible fairy tale
for the ages.

190
00:16:03,220 --> 00:16:04,780
It's a lot.

191
00:16:04,780 --> 00:16:07,620
Read it yourself.

192
00:16:27,660 --> 00:16:35,380
(A Question Largely Ignored by Trends
in Fundamental World Scientific Research)

193
00:16:49,740 --> 00:16:53,620
(Space Science and Technology)

194
00:16:57,940 --> 00:17:01,740
This file talks about
two ways to convert the results

195
00:17:01,740 --> 00:17:04,940
of fundamental scientific research
into practical applications:

196
00:17:04,940 --> 00:17:08,260
gradualistic mode and saltatory mode.

197
00:17:08,260 --> 00:17:09,540
That's right.

198
00:17:09,540 --> 00:17:12,300
Gradualistic mode refers to
theoretical, fundamental results

199
00:17:12,300 --> 00:17:15,180
being gradually applied to technology

200
00:17:15,180 --> 00:17:18,740
such as the development and application
of space technology.

201
00:17:18,740 --> 00:17:20,940
Saltatory mode means
theoretical, fundamental results

202
00:17:20,940 --> 00:17:23,620
rapidly become applied technology,

203
00:17:23,620 --> 00:17:26,460
(Nuclear Weapons)
leading to a technological leap.

204
00:17:26,460 --> 00:17:28,700
Examples include nuclear weapons.

205
00:17:28,700 --> 00:17:30,020
Yes.

206
00:17:30,020 --> 00:17:31,900
Now, both NATO and the Warsaw Pact

207
00:17:31,900 --> 00:17:33,780
are intensely active
in fundamental research

208
00:17:33,780 --> 00:17:35,860
and investing heavily in it.

209
00:17:35,860 --> 00:17:39,700
At this rate,
technological leaps may occur anytime.

210
00:17:39,700 --> 00:17:43,460
That will pose a major threat
to our strategic planning.

211
00:17:43,460 --> 00:17:48,380
Here it lists the fields
where such leaps are most likely:

212
00:17:48,380 --> 00:17:54,020
physics, biology, computer science.

213
00:17:58,380 --> 00:18:01,540
(SETI)

214
00:18:07,700 --> 00:18:11,380
The Search for
Extraterrestrial Intelligence.

215
00:18:16,900 --> 00:18:19,620
If a leap occurs in this field,

216
00:18:19,620 --> 00:18:25,580
its impact will exceed the sum of that
in the other three.

217
00:18:25,580 --> 00:18:28,580
That's what I'm talking about.

218
00:18:28,580 --> 00:18:34,220
Several NATO states
have already prioritized SETI.

219
00:18:34,220 --> 00:18:38,140
For example,
they launched Project Ozma

220
00:18:38,140 --> 00:18:40,540
(Green Bank Telescope at NRAO)
and built NRAO.

221
00:18:40,540 --> 00:18:42,700
(Concise Star Chart)
The project examined the stars

222
00:18:42,700 --> 00:18:48,740
Tau Ceti and Epsilon Eridani
and planned to broaden

223
00:18:48,740 --> 00:18:50,540
the frequency range in 1972.

224
00:18:50,540 --> 00:18:53,300
The Pioneer 10 and 11 probes
would be launched,

225
00:18:53,300 --> 00:18:55,140
each carrying a metal plaque

226
00:18:55,140 --> 00:18:58,060
with information about
civilization on Earth.

227
00:18:58,060 --> 00:19:02,180
And in 1977, they'd launch
the Voyager 1 and 2 probes,

228
00:19:02,180 --> 00:19:05,380
each with a metal audio record.

229
00:19:05,780 --> 00:19:08,300
This is the Arecibo Observatory.

230
00:19:08,300 --> 00:19:11,140
It's ready to use
and extremely powerful.

231
00:19:11,140 --> 00:19:13,460
Its effective energy collection area
is about 20 acres,

232
00:19:13,460 --> 00:19:17,740
greater than that of all the others
in the world combined.

233
00:19:17,740 --> 00:19:19,620
Together with the computer system,

234
00:19:19,620 --> 00:19:22,060
it can simultaneously monitor
65,000 channels,

235
00:19:22,060 --> 00:19:24,500
and it's capable of
ultrahigh energy transmissions.

236
00:19:24,500 --> 00:19:26,300
Look.

237
00:19:26,300 --> 00:19:28,220
This is in Europe.

238
00:19:28,220 --> 00:19:32,540
They've also made huge investments.

239
00:19:38,420 --> 00:19:41,500
The entire world is working on SETI.

240
00:19:41,500 --> 00:19:43,500
That's true.

241
00:19:43,500 --> 00:19:48,100
Except for us
who are paying little attention to it.

242
00:19:48,100 --> 00:19:53,140
You should know, if any country
gets in touch with extraterrestrials,

243
00:19:53,140 --> 00:19:58,220
it'll overturn the global landscape,
especially those superpowers.

244
00:19:58,220 --> 00:20:03,140
If they beat us to it,
we'll no longer have a chance.

245
00:20:03,620 --> 00:20:07,660
As a major socialist power,
we cannot fall behind.

246
00:20:07,660 --> 00:20:11,340
This unknown area must be conquered
for strategic importance.

247
00:20:11,340 --> 00:20:14,940
There's a long way ahead of us.

248
00:20:15,460 --> 00:20:18,900
Ye Wenjie, from this moment on,

249
00:20:18,900 --> 00:20:22,220
your job is to develop the Red Coast
Self-Interpreting Code System.

250
00:20:22,220 --> 00:20:27,020
Precisely,
using universal, basic mathematical,

251
00:20:27,020 --> 00:20:31,100
and physical laws to construct
an elemental linguistic code

252
00:20:31,100 --> 00:20:37,900
that can be understood by any civilization
that has mastered basic algebra,

253
00:20:37,900 --> 00:20:41,940
Euclidean geometry,
and the laws of nonrelativistic physics.

254
00:20:41,940 --> 00:20:46,220
Building on that,
create a brand-new linguistic system

255
00:20:46,220 --> 00:20:50,780
including Chinese and Esperanto.

256
00:20:52,260 --> 00:20:55,180
Do you get it?

257
00:20:56,260 --> 00:20:58,940
Yes, sir.

258
00:21:00,100 --> 00:21:04,620
So, the mysterious Red Coast Project
was established for SETI,

259
00:21:04,620 --> 00:21:11,300
and you alone created the Red Coast
Self-Interpreting Code System.

260
00:21:11,420 --> 00:21:16,820
At that time,
the Cold War was at its height.

261
00:21:16,820 --> 00:21:22,220
The insanity of the human race
had reached its historical zenith.

262
00:21:22,220 --> 00:21:27,820
Nuclear submarines and nuclear weapons
lurking in the corners

263
00:21:27,820 --> 00:21:31,220
could be launched at a moment's notice.

264
00:21:31,220 --> 00:21:36,260
Once they were let go,
hundreds of cities would be leveled,

265
00:21:36,260 --> 00:21:39,180
killing hundreds of millions of people.

266
00:21:39,180 --> 00:21:41,660
With such technical leaps in sight,

267
00:21:41,660 --> 00:21:48,260
an intense sense of crisis
was shared all over the world.

268
00:21:49,220 --> 00:21:52,500
Professor Ye, you're an astrophysicist.

269
00:21:52,500 --> 00:21:56,860
Do you really think astronomy
will be taking a technological leap?

270
00:21:56,860 --> 00:22:02,500
As destructive as nukes are, the universe

271
00:22:02,500 --> 00:22:05,180
is harboring even more terrible forces

272
00:22:05,180 --> 00:22:08,980
such as black holes and anti-matter.

273
00:22:08,980 --> 00:22:13,500
Compared with them, a nuclear bomb

274
00:22:13,940 --> 00:22:16,340
is nothing but a tiny candle.

275
00:22:19,220 --> 00:22:25,220
There used to be a waveform monitor.

276
00:22:25,220 --> 00:22:31,740
It was to display the waves
that Red Coast picked up from space.

277
00:22:31,740 --> 00:22:33,700
My daily work was to

278
00:22:33,700 --> 00:22:38,860
monitor and record that curve,

279
00:22:39,220 --> 00:22:45,620
waiting to hear from
the extraterrestrials.

280
00:22:53,460 --> 00:23:00,060
Over there, we had a radio receiver,

281
00:23:00,580 --> 00:23:02,820
quite sophisticated.

282
00:23:03,180 --> 00:23:09,500
A ruby-based traveling-wave maser
amplified the signals received by

283
00:23:09,500 --> 00:23:12,340
the gigantic antenna.

284
00:23:12,340 --> 00:23:15,460
But there was interference.

285
00:23:15,460 --> 00:23:18,700
Wouldn't it affect the accuracy?

286
00:23:18,700 --> 00:23:25,300
Wang, you're underestimating Red Coast.

287
00:23:25,300 --> 00:23:30,020
As immature as the technology was,

288
00:23:30,940 --> 00:23:34,420
it could do more than you think.

289
00:23:35,180 --> 00:23:38,420
The core of the reception system

290
00:23:38,420 --> 00:23:42,420
was immersed in
liquid helium at -269 degrees Celsius.

291
00:23:42,420 --> 00:23:48,820
A helicopter came to resupply
liquid helium regularly.

292
00:23:48,820 --> 00:23:52,980
The reception system was thus

293
00:23:53,780 --> 00:23:57,100
capable of picking up faint signals.

294
00:23:57,700 --> 00:24:02,180
Back then,
our monitoring range was

295
00:24:02,180 --> 00:24:08,300
within a radius of 1,000 light years,
containing some 20 million stars.

296
00:24:08,300 --> 00:24:13,620
Other than searching for and monitoring
possible extraterrestrial intelligence,

297
00:24:13,620 --> 00:24:15,540
we also tried to

298
00:24:15,540 --> 00:24:19,100
(20 Million Stars)
send messages to the universe

299
00:24:19,100 --> 00:24:24,660
to establish contact and communication.

300
00:24:24,660 --> 00:24:31,500
So did you really make such attempts?

301
00:24:35,140 --> 00:24:36,100
We did.

305
00:24:59,420 --> 00:25:05,180
Ye Wenjie and I
have redrafted the letter.

306
00:25:06,180 --> 00:25:11,060
Ye Wenjie, read it.

307
00:25:15,500 --> 00:25:18,980
(PLA Letter Paper)

308
00:25:22,380 --> 00:25:27,220
"We extend our best wishes to you,
inhabitants of another world.

309
00:25:27,220 --> 00:25:29,540
After reading the following message,

310
00:25:29,540 --> 00:25:34,420
you should have a basic understanding
of civilization on Earth.

311
00:25:34,420 --> 00:25:37,540
By dint of long toil and creativity,
the human race

312
00:25:37,540 --> 00:25:42,340
has built a splendid civilization,
blossoming with diverse cultures.

313
00:25:42,340 --> 00:25:48,060
We're also getting to know the laws of nature
and the development of human societies.

314
00:25:48,060 --> 00:25:50,420
We cherish all that we've accomplished.

315
00:25:50,420 --> 00:25:53,540
But our world is still flawed.

316
00:25:53,540 --> 00:25:59,620
Hate exists, as do prejudice and war.

317
00:25:59,620 --> 00:26:02,260
Contradictive productive forces
and relations

318
00:26:02,260 --> 00:26:04,940
are causing extremely
uneven distribution of wealth.

319
00:26:04,940 --> 00:26:09,820
And large portions of humanity
are living in poverty and misery.

320
00:26:09,820 --> 00:26:14,580
Human societies are working hard
to resolve the difficulties they face,

321
00:26:14,580 --> 00:26:18,380
striving to create a better future
for Earth civilization.

322
00:26:18,380 --> 00:26:24,180
The country that sent this message
is also engaged in this effort.

323
00:26:24,180 --> 00:26:27,380
We are dedicated to
building an ideal society

324
00:26:27,380 --> 00:26:32,500
where the labor and value of every human
are fully respected,

325
00:26:32,500 --> 00:26:38,100
and everyone's material
and spiritual needs are fully met

326
00:26:38,100 --> 00:26:41,580
so that civilization on Earth
may become more perfect.

327
00:26:41,580 --> 00:26:45,220
With the best of intentions,
we look forward to establishing contact

328
00:26:45,220 --> 00:26:48,540
with other civilized societies
in the universe.

329
00:26:48,540 --> 00:26:51,180
We look forward to working with you

330
00:26:51,180 --> 00:26:56,300
to build a better life in this vast universe."

331
00:26:56,820 --> 00:27:02,700
This letter of humans' best wishes
was sent to the universe.

332
00:27:04,380 --> 00:27:09,180
Enclosed was an overview of Earth,

333
00:27:09,180 --> 00:27:12,100
life on Earth,

334
00:27:12,100 --> 00:27:18,060
and human society
as well as basic world history.

335
00:27:18,060 --> 00:27:24,100
All that was sent after transmitting
the Self-interpreting Code System.

336
00:27:24,940 --> 00:27:28,980
Red Coast is a great project, no doubt.

337
00:27:30,980 --> 00:27:34,380
When sending messages to the universe,

338
00:27:35,900 --> 00:27:38,740
how did you ensure our security?

339
00:27:38,740 --> 00:27:44,980
It was carefully vetted
to ensure that it didn't give away

340
00:27:44,980 --> 00:27:50,500
the Earth's coordinates
relative to the Milky Way.

341
00:27:50,500 --> 00:27:57,140
At the 2,280 MHz, 12,000 MHz,
and 22,000 MHz channels,

342
00:27:57,140 --> 00:28:01,940
the transmission times
of the message were

343
00:28:01,940 --> 00:28:07,220
31 minutes, 7.5 minutes,
and 3.5 minutes respectively.

344
00:28:07,220 --> 00:28:10,860
Transmission at the higher-frequency
12,000 MHz

345
00:28:10,860 --> 00:28:14,860
and 22,000 MHz channels was minimized

346
00:28:14,860 --> 00:28:18,420
in case our location was exposed.

347
00:28:20,140 --> 00:28:25,180
Back in those days, SETI at Red Coast

348
00:28:25,420 --> 00:28:28,420
was marginalized research.

349
00:28:28,980 --> 00:28:33,540
But why such a high security rating?

350
00:28:33,940 --> 00:28:39,500
They asked the same question
at the very beginning of the Project

351
00:28:39,500 --> 00:28:45,620
and it was asked until the very end.

352
00:28:45,780 --> 00:28:51,100
But now,
you should have the answer.

353
00:28:51,500 --> 00:28:53,700
We can only marvel at the foresight

354
00:28:53,700 --> 00:28:58,100
of the top decision-maker of the Project.

355
00:29:00,740 --> 00:29:03,180
Had Red Coast succeeded,

356
00:29:04,580 --> 00:29:07,020
the world would be utterly different.

357
00:29:09,860 --> 00:29:15,660
Well, it's still too soon to tell
whether it succeeded or not.

358
00:29:15,660 --> 00:29:18,260
The radio waves sent out

359
00:29:18,260 --> 00:29:22,540
haven't gone too far in the universe yet.

360
00:29:23,260 --> 00:29:27,900
The farther the signals travel,
the weaker they become,

361
00:29:27,900 --> 00:29:33,900
and the less likely that any extraterrestrial
civilization will receive them.

362
00:29:35,860 --> 00:29:41,580
In order for extraterrestrials to detect
our signals,

363
00:29:41,580 --> 00:29:47,580
we broadcast at a power level equal to
the energy output of a mid-sized star.

364
00:29:47,580 --> 00:29:50,980
Soviet astrophysicist
Nicolai Kardashev once proposed

365
00:29:50,980 --> 00:29:53,780
that we could divide civilizations

366
00:29:53,780 --> 00:29:58,620
based on the power they could command
for communication purposes,

367
00:29:58,620 --> 00:30:01,580
He divided them into three types:

368
00:30:01,580 --> 00:30:04,420
A Type I civilization
can muster an amount of energy equal to

369
00:30:04,420 --> 00:30:07,740
the total output of the Earth.

370
00:30:07,740 --> 00:30:11,100
A Type II civilization
can marshal the energy equal to

371
00:30:11,100 --> 00:30:13,860
the output of a typical star.

372
00:30:13,860 --> 00:30:16,980
A Type III civilization
can utilize its communication energy

373
00:30:16,980 --> 00:30:20,900
equal to the energy output of a galaxy.

374
00:30:20,900 --> 00:30:26,260
Civilization on Earth is currently
not even a full Type I.

375
00:30:26,260 --> 00:30:30,100
And the transmissions from Red Coast
used only about one ten-thousandth

376
00:30:30,100 --> 00:30:33,820
of the power the Earth could muster.

377
00:30:33,820 --> 00:30:36,300
Our call wasn't any louder

378
00:30:37,780 --> 00:30:42,100
than the buzzing of a mosquito.

379
00:30:42,900 --> 00:30:45,460
No one could hear it.

380
00:30:45,460 --> 00:30:49,420
But the Type II and III civilizations
Kardashev proposed do exist,

381
00:30:49,420 --> 00:30:53,740
we should be able to hear them by now.

382
00:30:53,740 --> 00:30:59,180
In this case, our efforts seem to
have only proven one thing

383
00:30:59,180 --> 00:31:05,700
that in the vast universe,
only the Earth has intelligent life.

384
00:31:09,140 --> 00:31:16,020
Theoretically, there might never be
a definitive answer to that question.

385
00:31:16,020 --> 00:31:21,500
But emotionally, I and everyone else

386
00:31:21,740 --> 00:31:26,260
who went through Red Coast all believed so.

387
00:31:29,180 --> 00:31:31,740
Too bad the Project was decommissioned.

388
00:31:31,740 --> 00:31:37,180
It was there already
and should've kept going.

389
00:31:38,100 --> 00:31:42,100
It was a great cause worth fighting for.

390
00:31:44,580 --> 00:31:46,980
In the late 70s,

391
00:31:47,500 --> 00:31:52,140
there was a large-scale renovation.

392
00:32:10,180 --> 00:32:14,140
The transmission system was automated.

393
00:32:14,140 --> 00:32:18,300
Data processing of monitoring
became far more advanced.

394
00:32:18,300 --> 00:32:22,340
40,000 channels
could be monitored simultaneously.

395
00:32:22,340 --> 00:32:26,540
The more people knew, the clearer they became

396
00:32:26,540 --> 00:32:29,580
about the difficulty of SETI.

397
00:32:29,580 --> 00:32:36,140
And the leadership
lost interest in Red Coast.

398
00:32:37,260 --> 00:32:39,340
After the renovation,

399
00:32:39,340 --> 00:32:44,460
the first change we experienced
was lowered security rating.

400
00:32:44,460 --> 00:32:49,540
The security detail was reduced to
a group of five guards.

401
00:32:49,540 --> 00:32:52,260
Salute!

402
00:32:52,580 --> 00:32:56,620
Red Coast remained within
the Second Artillery Corps,

403
00:32:56,620 --> 00:32:58,580
but management
of its scientific activities

404
00:32:58,580 --> 00:33:02,020
was turned over to the Astronomy Institute
of Chinese Academy of Sciences.

405
00:33:02,020 --> 00:33:08,740
and it took on some research projects
that had nothing to do with SETI.

406
00:33:08,740 --> 00:33:14,620
I believe you achieved
most of your accomplishments then.

407
00:33:17,900 --> 00:33:23,860
At the time,
we had China's largest radio telescope.

408
00:33:23,860 --> 00:33:29,340
Following all those changes, we first took on
some radio astronomy projects.

409
00:33:29,340 --> 00:33:34,420
Later, more and more
such observatories were built,

410
00:33:34,420 --> 00:33:37,460
and Red Coast shifted to the observation and

411
00:33:37,460 --> 00:33:41,500
analysis of solar electromagnetic activity

412
00:33:41,500 --> 00:33:46,140
with an added solar telescope.

413
00:33:46,140 --> 00:33:49,500
I bet practical applications were a ton.

414
00:33:49,500 --> 00:33:51,060
Correct.

415
00:33:51,060 --> 00:33:55,420
The mathematical model we built
for solar electromagnetic activity

416
00:33:55,420 --> 00:33:59,460
was state-of-the-art.

417
00:33:59,460 --> 00:34:03,340
With such fruition,
the large investment in Red Coast

418
00:34:03,340 --> 00:34:06,460
saw a little bit of return.

419
00:34:06,460 --> 00:34:12,900
Actually, much of the credit
should go to Political Commissar Lei,

420
00:34:12,900 --> 00:34:17,260
although he did have his own agenda, too.

421
00:34:17,260 --> 00:34:20,180
Political Commissar Lei?

422
00:34:20,180 --> 00:34:24,140
Wasn't he a political officer
in that technical unit?

423
00:34:24,140 --> 00:34:29,500
Before enlisting,
he had studied astrophysics as well.

424
00:34:29,500 --> 00:34:35,660
Research projects we took on
outside of SETI were all due to his efforts.

425
00:34:40,260 --> 00:34:45,380
It wasn't easy
to return to technical work.

426
00:34:45,380 --> 00:34:51,900
Without Lei,
Red Coast would've been long gone.

427
00:34:51,900 --> 00:34:55,580
When it was converted for civil use,

428
00:34:55,580 --> 00:34:59,620
the military basically abandoned it.

429
00:34:59,620 --> 00:35:04,940
Chinese Academy of Sciences
could no longer keep the base running.

430
00:35:04,940 --> 00:35:11,420
Inevitably, it was shut down.

431
00:35:49,900 --> 00:35:55,620
In the dead of the night, when I was alone

432
00:35:55,940 --> 00:35:58,300
in the empty monitoring room,

433
00:35:58,300 --> 00:36:00,820
I could hear in my headphones

434
00:36:00,820 --> 00:36:05,860
the lifeless noise of the universe.

435
00:36:05,860 --> 00:36:10,140
It was faint but continuous,

436
00:36:10,940 --> 00:36:13,420
more eternal than the stars.

437
00:36:15,420 --> 00:36:20,980
Sometimes I thought it sounded like

438
00:36:20,980 --> 00:36:26,780
the endless cold winds of Radar Peak.

439
00:36:26,780 --> 00:36:30,420
I was chilled to the bone.

440
00:36:31,140 --> 00:36:33,420
There weren't enough words

441
00:36:34,460 --> 00:36:37,740
to describe such loneliness.

442
00:36:40,180 --> 00:36:46,420
SETI is quite a unique discipline.

443
00:36:46,420 --> 00:36:52,140
It can shape researchers' perspectives
on life.

444
00:36:54,300 --> 00:36:58,700
It occurred to me repeatedly
that life was truly an accident

445
00:36:58,700 --> 00:37:04,060
among all the accidents in the universe.

446
00:37:04,060 --> 00:37:09,700
And the universe was an empty palace

447
00:37:10,660 --> 00:37:17,900
in which humankind was the only ant.

448
00:37:43,700 --> 00:37:49,580
This kind of thinking made me live
a conflicted life since.

449
00:37:51,460 --> 00:37:55,740
Sometimes I thought life was precious

450
00:37:56,340 --> 00:37:59,460
and more important than anything.

451
00:38:01,020 --> 00:38:03,820
But other times,

452
00:38:03,820 --> 00:38:10,540
I found humans so insignificant
that nothing was worthwhile.

453
00:38:10,540 --> 00:38:15,820
Anyway, despite such internal conflicts,

454
00:38:15,820 --> 00:38:17,860
my life slipped away,

455
00:38:18,940 --> 00:38:24,860
and before I knew it,
I was already old.

456
00:38:34,300 --> 00:38:39,700
I'm not getting any younger
or healthier.

457
00:38:39,700 --> 00:38:43,100
I can't predict the future.

458
00:38:43,220 --> 00:38:49,580
All I can do is live my life as it is.
