1
00:00:00,040 --> 00:00:02,080
Speaker 1: I want you to imagine something with me for a second.

2
00:00:02,399 --> 00:00:06,759
Picture yourself walking through this really dense ancient forest.

3
00:00:06,519 --> 00:00:08,279
Speaker 2: Okay, sitting the scene. I like it.

4
00:00:08,439 --> 00:00:11,839
Speaker 1: Yeah, but it isn't you know, a lovely sun dappled

5
00:00:12,039 --> 00:00:15,759
afternoon hike. It is the absolute dead of night.

6
00:00:15,720 --> 00:00:17,960
Speaker 2: Oh right, the kind of dark where your eyes never

7
00:00:18,039 --> 00:00:19,839
actually adjust exactly.

8
00:00:19,920 --> 00:00:24,199
Speaker 1: We were talking about pitch black, suffocating darkness. The tree

9
00:00:24,239 --> 00:00:27,920
canopy is completely blocking out the moon and the stars.

10
00:00:27,960 --> 00:00:31,519
You're navigating over these unseen roots. The air is freezing cold,

11
00:00:32,159 --> 00:00:36,119
and you have this creeping, unshakable, primal instinct that this

12
00:00:36,320 --> 00:00:39,320
environment is just well, it's dangerous.

13
00:00:39,399 --> 00:00:41,000
Speaker 2: You don't know what's out there in the trees.

14
00:00:40,840 --> 00:00:42,679
Speaker 1: Right, You don't know if it's a predator, a steep

15
00:00:42,759 --> 00:00:45,520
drop off, or just empty woods. All you know is

16
00:00:45,520 --> 00:00:48,399
that you need to survive the trek. So, relying on

17
00:00:48,439 --> 00:00:50,799
your modern tools, you reach into your bag and pull

18
00:00:50,840 --> 00:00:54,079
out a massive, heavy duty, high luman flashlight.

19
00:00:54,600 --> 00:00:56,759
Speaker 2: Very natural human response. Yeah, we want to see the

20
00:00:56,799 --> 00:00:58,159
threat exactly.

21
00:00:58,320 --> 00:01:01,479
Speaker 1: You flick the switch and this brilliant beam of white

22
00:01:01,520 --> 00:01:04,359
light violently cuts through the darkness. You start waving it

23
00:01:04,359 --> 00:01:07,680
all around you, sweeping it through the branches, illuminating the path,

24
00:01:07,799 --> 00:01:10,239
just trying to see what is like ten feet ahead

25
00:01:10,280 --> 00:01:10,519
of you.

26
00:01:10,680 --> 00:01:13,560
Speaker 2: And it works right for a second, you feel safe.

27
00:01:13,599 --> 00:01:16,840
Speaker 1: You do for a brief moment. Having that light makes

28
00:01:16,879 --> 00:01:20,920
you feel incredibly secure. You can see the immediate obstacles,

29
00:01:21,040 --> 00:01:23,760
you can avoid tripping over a log. But what you

30
00:01:23,799 --> 00:01:27,359
are completely ignoring in that fleeting moment of false security

31
00:01:27,519 --> 00:01:31,599
is a well a terrifying reality of physics, which is that.

32
00:01:31,519 --> 00:01:33,680
Speaker 2: The light travels a lot further than ten feet.

33
00:01:33,879 --> 00:01:37,840
Speaker 1: Exactly, in a truly dark forest, that brilliant beam of

34
00:01:37,920 --> 00:01:40,120
light you are waving around to see ten feet ahead

35
00:01:40,480 --> 00:01:43,480
can be seen for miles by absolutely anything else that

36
00:01:43,599 --> 00:01:44,680
might be out there in the dark.

37
00:01:44,959 --> 00:01:48,680
Speaker 2: That is a man. That's a profound visceral scenario. It

38
00:01:48,760 --> 00:01:51,920
perfectly encapsulates the grand illusion of observation.

39
00:01:51,560 --> 00:01:52,560
Speaker 1: The illusion of control.

40
00:01:52,879 --> 00:01:57,400
Speaker 2: Yes, exactly, the flashlight provides a temporary, localized illusion of control.

41
00:01:57,959 --> 00:02:00,640
You believe that because you are holding the you're the

42
00:02:00,680 --> 00:02:03,959
primary observer, you feel like the active participant.

43
00:02:03,480 --> 00:02:06,719
Speaker 1: In the environment, but you're actually just making yourself a target.

44
00:02:07,000 --> 00:02:11,479
Speaker 2: Precisely, the physical reality of electromagnetic radiation, which is all

45
00:02:11,599 --> 00:02:15,479
light is, really dictates that the very act of trying

46
00:02:15,520 --> 00:02:19,560
to observe your immediate surroundings has just transformed you into

47
00:02:19,560 --> 00:02:23,560
the most highly visible, undeniable target in the entire ecosystem.

48
00:02:23,639 --> 00:02:27,000
Speaker 1: You trade your localized site for generalized exposure.

49
00:02:26,680 --> 00:02:28,599
Speaker 2: Right, You are practically screaming, I am.

50
00:02:28,560 --> 00:02:32,479
Speaker 1: Right here, and that trade off, that terrifying accidental exposure,

51
00:02:32,560 --> 00:02:36,639
is exactly what we are unpacking today. Welcome to Thrilling Threads.

52
00:02:36,800 --> 00:02:38,639
I am so glad you have chosen to join us

53
00:02:38,639 --> 00:02:41,560
for this journey because our mission today is to pull

54
00:02:41,599 --> 00:02:43,919
back the curtain on something that is happening right over

55
00:02:43,960 --> 00:02:46,439
our heads every single second of the day, and.

56
00:02:46,400 --> 00:02:48,159
Speaker 2: It goes completely unnoticed by most.

57
00:02:47,960 --> 00:02:51,719
Speaker 1: Of us completely. We are synthesizing recent astronomical models, deep

58
00:02:51,759 --> 00:02:56,520
atmospheric chemistry research, and deep space telemetry studies to reveal

59
00:02:56,840 --> 00:03:01,520
the ten accidental, unavoidable ways humanity is effectively screaming its

60
00:03:01,560 --> 00:03:04,159
exact location into the cosmic void, along with.

61
00:03:04,120 --> 00:03:07,280
Speaker 2: Our specific technological vulnerabilities, which is the really scary part.

62
00:03:07,520 --> 00:03:09,680
Speaker 1: Yeah, that's a huge piece of this. And the operative

63
00:03:09,680 --> 00:03:11,560
word there is accidental, right.

64
00:03:11,400 --> 00:03:14,719
Speaker 2: Because when most people think about humanity communicating with the cosmos,

65
00:03:15,120 --> 00:03:19,719
their minds naturally gravitate toward our deliberate, poetic attempts to

66
00:03:19,719 --> 00:03:20,599
say hello.

67
00:03:20,599 --> 00:03:23,960
Speaker 1: Like the Voyager probes launched back in the nineteen seventies.

68
00:03:23,479 --> 00:03:25,439
Speaker 2: Exactly the famous Golden Record.

69
00:03:25,680 --> 00:03:29,879
Speaker 1: Yeah. We attached these beautiful gold plated copper disks to

70
00:03:29,960 --> 00:03:33,360
the outside of the spacecraft. We encoded them with greetings

71
00:03:33,400 --> 00:03:35,159
in what fifty five languages?

72
00:03:35,199 --> 00:03:39,639
Speaker 2: Fifty five languages, the sound of a mother's kiss, a heartbeat.

73
00:03:39,319 --> 00:03:42,680
Speaker 1: A little Mozart, some chuck Berry, and a map showing

74
00:03:42,719 --> 00:03:46,800
the location of our sun relative to nearby pulsars. It

75
00:03:46,879 --> 00:03:50,960
was this carefully curated, highly romanticized message of peace.

76
00:03:51,199 --> 00:03:55,319
Speaker 2: It was a beautiful gesture truly, but from an astrophysical standpoint,

77
00:03:55,680 --> 00:03:57,199
it is functionally irrelevant.

78
00:03:57,240 --> 00:03:59,039
Speaker 1: Wait, really irrelevant completely.

79
00:03:59,280 --> 00:04:01,840
Speaker 2: I mean, the sansmitter on the Voider spacecraft operates at

80
00:04:01,879 --> 00:04:02,879
roughly twenty watts.

81
00:04:03,039 --> 00:04:05,080
Speaker 1: Twenty watts, that's nothing.

82
00:04:05,159 --> 00:04:07,719
Speaker 2: It's less power than the light bulb inside your refrigerator.

83
00:04:08,280 --> 00:04:11,479
The probe itself is tiny, it's cold, and it's drifting

84
00:04:11,560 --> 00:04:14,919
silently through the unfathomable emptiness of the ort cloud.

85
00:04:15,199 --> 00:04:16,920
Speaker 1: So nobody is ever going to find it.

86
00:04:17,560 --> 00:04:21,000
Speaker 2: The chances of an extraterrestrial intelligence ever stumbling across that

87
00:04:21,040 --> 00:04:26,480
physical object are so mathematically infinitesimal that they essentially border

88
00:04:26,480 --> 00:04:29,600
on zero. We really shouldn't be worrying about the poetic

89
00:04:29,600 --> 00:04:30,959
messages we put in a bottle.

90
00:04:31,199 --> 00:04:34,720
Speaker 1: We need to be looking at the massive, chaotic industrial

91
00:04:34,800 --> 00:04:38,079
noise we are generating simply by existing.

92
00:04:37,920 --> 00:04:42,240
Speaker 2: Exactly the unavoidable messy byproducts of modern life.

93
00:04:42,040 --> 00:04:44,240
Speaker 1: Like the smartphone sitting on the desk next to you

94
00:04:44,360 --> 00:04:46,680
right now, or the commercial flight you took to visit

95
00:04:46,720 --> 00:04:48,480
your family last summer, the way.

96
00:04:48,279 --> 00:04:51,240
Speaker 2: We cool our homes, the way we light our streets at.

97
00:04:51,199 --> 00:04:54,319
Speaker 1: Night, just the basic infrastructure we rely on to keep

98
00:04:54,360 --> 00:04:56,160
the global economy from collapsing.

99
00:04:56,319 --> 00:04:58,800
Speaker 2: Right, when you strip away the poetry and look at

100
00:04:58,800 --> 00:05:02,759
the raw data and the astrophysical models, a very stark

101
00:05:02,839 --> 00:05:09,240
picture emerges. This mundane infrastructure acts as a continuous omnidirectional broadcast.

102
00:05:09,360 --> 00:05:12,120
Speaker 1: We're generating what astronomers call techno signatures.

103
00:05:12,319 --> 00:05:16,319
Speaker 2: Yes, and the sheer intensity and scale of these technosignatures

104
00:05:16,319 --> 00:05:17,360
are just staggering.

105
00:05:17,639 --> 00:05:19,920
Speaker 1: Let's dive right into that scale, then, starting with the

106
00:05:19,920 --> 00:05:23,519
invisible rhythm of our daily lives, Because our modern world

107
00:05:23,560 --> 00:05:27,879
requires massive transit and communication infrastructure to function, right, and

108
00:05:27,920 --> 00:05:31,199
that creates a continuous electromagnetic pulse it does.

109
00:05:31,480 --> 00:05:34,720
Speaker 2: And the first major techno signature in the research focuses

110
00:05:34,759 --> 00:05:38,959
on global aviation, specifically airport readar systems.

111
00:05:39,319 --> 00:05:41,560
Speaker 1: Now, when most of us think of air traffic control,

112
00:05:41,680 --> 00:05:44,759
we think of it as a highly localized safety measure.

113
00:05:45,199 --> 00:05:47,600
You have a spinning dish at a major airport like

114
00:05:47,639 --> 00:05:49,480
Heathrow or JFK.

115
00:05:49,399 --> 00:05:52,000
Speaker 2: Right, bouncing radio waves off the metallic hull of the

116
00:05:52,040 --> 00:05:54,480
passenger jet a few miles up in the sky, just to.

117
00:05:54,439 --> 00:05:57,199
Speaker 1: Make sure planes don't collide. It seems totally contained.

118
00:05:57,560 --> 00:06:00,879
Speaker 2: It seems contained because our biological senses are limited, we

119
00:06:01,000 --> 00:06:04,000
can't naturally see radio frequencies, so we just assume they

120
00:06:04,040 --> 00:06:05,639
stop where their usefulness ends.

121
00:06:05,480 --> 00:06:07,439
Speaker 1: Out of sight, out of mind exactly.

122
00:06:07,920 --> 00:06:11,040
Speaker 2: But electromagnetism doesn't care about our intentions. An air traffic

123
00:06:11,040 --> 00:06:14,639
control radar operates by firing an intense burst of radio

124
00:06:14,639 --> 00:06:17,959
frequency energy outward. A tiny fraction of a percent of

125
00:06:18,000 --> 00:06:20,800
that energy hits the airplane and reflects back to the

126
00:06:20,800 --> 00:06:22,040
receiver on the ground.

127
00:06:22,120 --> 00:06:24,240
Speaker 1: But the other ninety nine point nine percent of that

128
00:06:24,360 --> 00:06:26,279
energy doesn't just evaporate.

129
00:06:25,839 --> 00:06:29,240
Speaker 2: No, it doesn't. Radio waves in these specific frequencies are

130
00:06:29,319 --> 00:06:32,279
highly penetrative. They don't get absorbed by the clouds. They

131
00:06:32,279 --> 00:06:34,160
aren't stopped by the upper atmosphere.

132
00:06:34,199 --> 00:06:38,600
Speaker 1: They pierce right through the ionosphere completely unobstructed, and travel

133
00:06:38,720 --> 00:06:42,680
outward into the absolute vacuum of space at the speed of.

134
00:06:42,759 --> 00:06:46,279
Speaker 2: Light one hundred and eighty six thousand miles per second.

135
00:06:46,600 --> 00:06:48,800
Speaker 1: And we aren't just talking about one airport here. We

136
00:06:48,839 --> 00:06:52,680
are talking about the aggregate of the entire global aviation.

137
00:06:52,480 --> 00:06:56,639
Speaker 2: Infrastructure, civilian airports, military bases, weather tracking.

138
00:06:56,240 --> 00:07:01,519
Speaker 1: Stations, thousands of high powered radar systems, continues scanning massive

139
00:07:01,600 --> 00:07:05,399
volumes of airspace twenty four hours a day. The sources

140
00:07:05,439 --> 00:07:08,839
calculate the total energy output of this global radar web,

141
00:07:08,879 --> 00:07:11,759
and the number is well, it almost breaks the human brain.

142
00:07:11,879 --> 00:07:12,600
Speaker 2: It's massive.

143
00:07:12,759 --> 00:07:18,040
Speaker 1: We are emitting approximately two quadrillion watts of radio power continuously.

144
00:07:18,160 --> 00:07:22,040
Speaker 2: Two quadrillion. Wants to put that into perspective, that is

145
00:07:22,160 --> 00:07:26,040
roughly equivalent to the entire solar energy striking a significant

146
00:07:26,079 --> 00:07:30,360
portion of the Earth's surface, but concentrated entirely into specific

147
00:07:30,519 --> 00:07:32,600
narrow bands of the radio spectrum.

148
00:07:32,680 --> 00:07:36,120
Speaker 1: So, if an extraterrestrial civilization has radio telescopes comparable to

149
00:07:36,120 --> 00:07:38,480
the ones we have built here on Earth, facilities like

150
00:07:38,879 --> 00:07:42,759
the Very Large Array or the newly constructed square kilometer array. Right,

151
00:07:42,759 --> 00:07:45,639
If they have those, Earth doesn't look like a quiet, dim,

152
00:07:45,759 --> 00:07:50,040
rocky sphere in the radio spectrum. Earth is a blindingly bright,

153
00:07:50,319 --> 00:07:51,360
chaotic beacon.

154
00:07:51,560 --> 00:07:54,279
Speaker 2: It is, but it's not just a steady glow. And

155
00:07:54,279 --> 00:07:56,000
I think this is the most fascinating part of the

156
00:07:56,079 --> 00:08:00,680
radar signature. Earth isn't stationary. It's a rotating sphere.

157
00:08:01,079 --> 00:08:05,160
Speaker 1: Right. We spin, So imagine you have these massive concentrator

158
00:08:05,199 --> 00:08:11,199
hubs of radar activity at major metropolitan centers New York, London, Tokyo, Dubai.

159
00:08:11,319 --> 00:08:14,040
Speaker 2: Yes, And as the Earth spins on its axis, these

160
00:08:14,079 --> 00:08:17,759
localized hubs of intense radiation rise over the horizon and

161
00:08:17,800 --> 00:08:21,439
then eventually set from the perspective of a distant star, it.

162
00:08:21,439 --> 00:08:25,199
Speaker 1: Creates this rhythmic sweeping pattern. To an outside observer, Earth

163
00:08:25,319 --> 00:08:27,720
operates exactly like a cosmic lighthouse.

164
00:08:27,879 --> 00:08:29,920
Speaker 2: A cosmic lighthouse is the perfect analogy.

165
00:08:30,000 --> 00:08:33,559
Speaker 1: The beam of two quadrillion watts of radio energy literally

166
00:08:33,600 --> 00:08:36,960
sweeps across the galactic ocean in a highly predictable pattern.

167
00:08:37,159 --> 00:08:40,919
Speaker 2: And that predictable pattern is the absolute crux of the issue.

168
00:08:41,000 --> 00:08:42,840
If we look at this from the perspective of an

169
00:08:42,840 --> 00:08:47,399
extraterrestrial astronomer situated within say, fifty one hundred light years

170
00:08:47,399 --> 00:08:47,679
of us.

171
00:08:47,759 --> 00:08:49,799
Speaker 1: They don't need to decode the radar signal.

172
00:08:49,600 --> 00:08:51,559
Speaker 2: No, not at all. They don't need to understand that

173
00:08:51,559 --> 00:08:54,519
the signal is tracking a Boeing seven seven seven seven

174
00:08:54,559 --> 00:08:57,960
flying over Chicago. They simply point their instruments toward our

175
00:08:58,000 --> 00:09:01,919
star system and they notice a high, highly localized, incredibly

176
00:09:01,960 --> 00:09:03,919
structured pulse of microwave radiation.

177
00:09:04,360 --> 00:09:07,519
Speaker 1: And the key detail, the dead giveaway, right, is that

178
00:09:07,559 --> 00:09:10,600
this pulse is perfectly synchronized with the rotation rate of

179
00:09:10,600 --> 00:09:11,120
our planet.

180
00:09:11,240 --> 00:09:13,679
Speaker 2: Exactly, it's sync to the rotation of a small, rocky

181
00:09:13,720 --> 00:09:15,799
planet in the habitable zone of that star.

182
00:09:16,000 --> 00:09:19,360
Speaker 1: Because nature on its own doesn't produce that kind of

183
00:09:19,399 --> 00:09:20,879
highly specific synchronization.

184
00:09:21,120 --> 00:09:23,759
Speaker 2: No it doesn't. I mean nature produces an abundance of

185
00:09:23,840 --> 00:09:28,759
radio waves. Pulsars sweep regular beams of radiation across the sky, quasars,

186
00:09:28,759 --> 00:09:31,879
and active galactic nuclei just roll with radio noise.

187
00:09:32,000 --> 00:09:35,960
Speaker 1: Even our own sun produces massive radio bursts during solar flares.

188
00:09:36,240 --> 00:09:41,399
Speaker 2: Sure, but natural astrophysical phenomena do not create perfectly synchronized,

189
00:09:41,759 --> 00:09:46,039
geographically clustered microwave pulses that happen to track perfectly with

190
00:09:46,120 --> 00:09:48,360
a twenty four hour diurnal rotation.

191
00:09:48,600 --> 00:09:53,440
Speaker 1: That mathematical rhythm, that localized rotating beacon is the undeniable

192
00:09:53,440 --> 00:09:56,480
heartbeat of a complex, mechanized society.

193
00:09:56,639 --> 00:09:59,720
Speaker 2: It is the definitive proof of engineering. We built our

194
00:09:59,720 --> 00:10:03,039
air graphic control systems purely for localized safety, but for

195
00:10:03,080 --> 00:10:06,559
the last seven decades, every single time a radar dish

196
00:10:06,559 --> 00:10:09,679
sweeps the horizon, it fires a flare into the cosmos.

197
00:10:09,919 --> 00:10:13,519
Speaker 1: Any civilization watching the skies for signs of emerging technology

198
00:10:13,559 --> 00:10:17,559
would instantly recognize that Earth hosts an industrialized species without

199
00:10:17,559 --> 00:10:20,159
a does we are literally announcing our existence to the

200
00:10:20,200 --> 00:10:23,200
galaxy just by trying to manage our daily commutes and

201
00:10:23,240 --> 00:10:26,840
holiday travel. That is wild to think about, but radar

202
00:10:26,960 --> 00:10:29,799
is a targeted, highly structured sweep. The research points out

203
00:10:29,840 --> 00:10:32,480
another layer to this invisible rhythm that is much more.

204
00:10:32,360 --> 00:10:35,000
Speaker 2: Defense and honestly, it hits a lot closer to home

205
00:10:35,039 --> 00:10:38,039
for every single person listening to this right now, right.

206
00:10:38,159 --> 00:10:40,799
Speaker 1: We need to transition from the massive spinning dishes at

207
00:10:40,799 --> 00:10:44,080
the airport to the mobile phone you are probably holding

208
00:10:44,080 --> 00:10:46,679
in your hand or have sitting in your pocket. Let's

209
00:10:46,679 --> 00:10:48,960
talk about the cellular communication network.

210
00:10:49,240 --> 00:10:53,240
Speaker 2: This represents a massive evolution in our planetary signature. Over

211
00:10:53,279 --> 00:10:57,080
the last twenty to thirty years, humanity has enveloped the

212
00:10:57,120 --> 00:11:01,320
surface of the Earth in a dense, interlock continuous web

213
00:11:01,720 --> 00:11:03,120
of cellular communication.

214
00:11:03,440 --> 00:11:05,840
Speaker 1: We are no longer talking about a few thousand high

215
00:11:05,879 --> 00:11:09,240
powered radar dishes. We are talking about millions of cell

216
00:11:09,320 --> 00:11:13,320
towers constantly pinging billions of individual mobile devices.

217
00:11:13,440 --> 00:11:17,399
Speaker 2: It is an intimate, localized technology that has scaled to

218
00:11:17,440 --> 00:11:18,519
a planetary level.

219
00:11:18,840 --> 00:11:22,120
Speaker 1: It really puts things into a strange perspective. Our basic

220
00:11:22,200 --> 00:11:24,759
human desire to just scroll through social media, or to

221
00:11:24,799 --> 00:11:26,879
send a quick text message to a friend asking what

222
00:11:26,879 --> 00:11:28,200
they want for dinner, or to.

223
00:11:28,240 --> 00:11:30,519
Speaker 2: Stream a deep dive on a podcast while you walk the.

224
00:11:30,480 --> 00:11:34,039
Speaker 1: Dog right, all of that collectively creates this continuous, low

225
00:11:34,120 --> 00:11:37,639
level hum of microwave radiation. The sources describe it as

226
00:11:37,679 --> 00:11:42,279
a broadband electromagnetic halo that literally wraps around the entire globe.

227
00:11:42,360 --> 00:11:46,159
Speaker 2: It is a phenomenal concept. We have constructed an artificial

228
00:11:46,240 --> 00:11:50,600
electromagnetic atmosphere, and this shifting nature of that halo is

229
00:11:50,639 --> 00:11:53,759
what makes it such a potent and undeniable techno signature.

230
00:11:54,159 --> 00:11:57,120
Speaker 1: Because, unlike the radar beam which sweaks past a distant

231
00:11:57,159 --> 00:11:59,480
star and vanishes for a few hours until the Earth

232
00:11:59,559 --> 00:12:00,360
rotates again.

233
00:12:00,519 --> 00:12:04,559
Speaker 2: The radiation from our global mobile networks is continuous, but

234
00:12:05,519 --> 00:12:08,519
this is key, It is not uniform. It fluctuates in

235
00:12:08,519 --> 00:12:11,480
a highly specific, mathematically trackable.

236
00:12:11,039 --> 00:12:12,480
Speaker 1: Way because of the time zones.

237
00:12:12,600 --> 00:12:16,840
Speaker 2: Exactly. Recent astrophysical studies have modeled exactly what this cellular

238
00:12:16,879 --> 00:12:20,120
leakage looks like from neighboring star systems such as Alpha

239
00:12:20,120 --> 00:12:21,720
Centauri or Barnard's Star.

240
00:12:21,679 --> 00:12:23,639
Speaker 1: And what does it actually look like. Because we aren't

241
00:12:23,639 --> 00:12:26,559
broadcasting high powered booms into space with our phones. The

242
00:12:26,600 --> 00:12:28,679
antennas inside our phones are tiny.

243
00:12:28,919 --> 00:12:31,879
Speaker 2: Individually, they are microscopic in the grand scheme of things,

244
00:12:31,919 --> 00:12:35,120
but in the aggregate they create a steady, unnatural glow

245
00:12:35,320 --> 00:12:38,639
in the microwave spectrum. And here is where the behavior

246
00:12:38,679 --> 00:12:40,799
of the species reveals itself.

247
00:12:40,519 --> 00:12:42,159
Speaker 1: The waking and sleeping cycles.

248
00:12:42,600 --> 00:12:46,679
Speaker 2: Yes, as the planet rotates, the terminator line, the line

249
00:12:46,679 --> 00:12:49,879
dividing day and night, moves across the continents. As massive

250
00:12:49,960 --> 00:12:53,000
population centers in Asia wake up in the morning, billions

251
00:12:53,000 --> 00:12:56,559
of devices connect, network traffic spikes, and the intensity of

252
00:12:56,559 --> 00:12:58,600
that microwave glow sharply increases.

253
00:12:59,039 --> 00:13:01,480
Speaker 1: A few hours later, Europe wakes up and a new

254
00:13:01,559 --> 00:13:03,519
geographical node of the Halo.

255
00:13:03,279 --> 00:13:06,799
Speaker 2: Bradons and the Americas. People wake up, they check their emails,

256
00:13:06,799 --> 00:13:10,919
they navigate traffic, they stream media, and the network just roars.

257
00:13:11,679 --> 00:13:14,039
And then as the evening falls, they eventually go to

258
00:13:14,080 --> 00:13:16,480
sleep and the localized network quiets down.

259
00:13:16,960 --> 00:13:19,679
Speaker 1: So an alien astronomer wouldn't just know we're here. They

260
00:13:19,679 --> 00:13:21,480
could literally chart our bedtimes.

261
00:13:21,559 --> 00:13:22,559
Speaker 2: They absolutely could.

262
00:13:22,639 --> 00:13:26,799
Speaker 1: We are broadcasting the daily biological rhythm of human life

263
00:13:27,360 --> 00:13:31,240
mapped onto our technological infrastructure in real time. That is

264
00:13:31,320 --> 00:13:32,960
so creepy and so fascinating.

265
00:13:33,039 --> 00:13:36,039
Speaker 2: That is the crucial takeaway. They wouldn't need to intercept

266
00:13:36,120 --> 00:13:38,919
the data packets. They wouldn't need to decode your text

267
00:13:38,960 --> 00:13:41,879
messages or decrypt your banking app to understand what they

268
00:13:41,879 --> 00:13:42,480
are looking at.

269
00:13:42,600 --> 00:13:44,559
Speaker 1: The medium is the message, right.

270
00:13:45,279 --> 00:13:48,799
Speaker 2: The sheer volume of the radiation, combined with its geometric

271
00:13:48,840 --> 00:13:52,480
distribution across the planet's surface and its strict adherence to

272
00:13:52,519 --> 00:13:55,759
a biological waking and sleeping cycle, tells them everything they

273
00:13:55,840 --> 00:13:56,240
need to know.

274
00:13:56,759 --> 00:14:01,240
Speaker 1: It proves the existence of a highly interconnected, technologically dependent

275
00:14:01,320 --> 00:14:04,320
species that has achieved global synchronization.

276
00:14:05,120 --> 00:14:09,120
Speaker 2: Furthermore, as developing nations build out their infrastructure and as

277
00:14:09,159 --> 00:14:13,799
the entire globe transitions to denser, higher frequency networks like five.

278
00:14:13,679 --> 00:14:16,799
Speaker 1: G and increasingly satellite based cellular networks too.

279
00:14:17,080 --> 00:14:20,960
Speaker 2: Yes, exactly, this microwave halo is growing brighter, denser, and

280
00:14:21,039 --> 00:14:22,840
more complex every single day.

281
00:14:23,159 --> 00:14:25,440
Speaker 1: We are just wrapping ourselves in a louder and louder

282
00:14:25,440 --> 00:14:28,480
blanket of statics. So the radar in the cell networks

283
00:14:28,519 --> 00:14:31,960
represent our ambient noise. It's the background hum of humanity

284
00:14:32,080 --> 00:14:34,639
just talking to each other and managing our internal.

285
00:14:34,279 --> 00:14:36,159
Speaker 2: Logistics our accidental leakage.

286
00:14:36,240 --> 00:14:39,080
Speaker 1: Right, But there is a massive conceptual leap we need

287
00:14:39,120 --> 00:14:41,840
to make here. It's one thing to accidentally leak energy

288
00:14:41,840 --> 00:14:44,840
while you're looking at yourself. What happens when humanity stops

289
00:14:44,879 --> 00:14:48,639
looking inward and we intentionally aim our most powerful technology

290
00:14:48,679 --> 00:14:50,240
out into the absolute dark.

291
00:14:50,519 --> 00:14:54,000
Speaker 2: This is where it gets highly directional and deeply dangerous.

292
00:14:54,080 --> 00:14:58,480
Speaker 1: Exactly, this brings us to a deeply fascinating and somewhat

293
00:14:58,600 --> 00:15:04,039
terrifying section of the research deep space communications and planetary radar.

294
00:15:04,960 --> 00:15:08,159
We are essentially firing blind into the universe.

295
00:15:08,720 --> 00:15:11,919
Speaker 2: It is a vital distinction to make The ambient leakage

296
00:15:11,960 --> 00:15:16,240
from cell phones and airport radar is omnidirectional, it spreads

297
00:15:16,279 --> 00:15:19,360
out and becomes relatively diffuse by the time it reaches

298
00:15:19,440 --> 00:15:20,519
interstellar distances.

299
00:15:20,679 --> 00:15:23,600
Speaker 1: But when we discuss the Deep Space Network the DSN,

300
00:15:23,720 --> 00:15:26,720
operated by space agencies like NASA.

301
00:15:26,240 --> 00:15:30,480
Speaker 2: We are dealing with highly focused, incredibly concentrated, and intensely

302
00:15:30,559 --> 00:15:34,000
powerful transmissions. When scientists want to command a rover that

303
00:15:34,080 --> 00:15:36,639
is creeping across the rust red sands of Mars, or

304
00:15:36,639 --> 00:15:39,000
when they need to transmit a complex software patch to

305
00:15:39,039 --> 00:15:41,759
a probe orbiting the turbulent atmosphere.

306
00:15:41,320 --> 00:15:43,679
Speaker 1: Of Jupiter, they cannot rely on a diffuse broadcasts no.

307
00:15:43,879 --> 00:15:46,759
Speaker 2: They'd never reach it. They use global arrays of massive

308
00:15:46,840 --> 00:15:50,000
seventy meters wide radio intennas to be in intense, highly

309
00:15:50,039 --> 00:15:53,279
structured data streams directly at those robotic targets.

310
00:15:53,360 --> 00:15:56,799
Speaker 1: It is precision communication on an interplanetary scale. And I

311
00:15:56,840 --> 00:15:59,200
want to make sure we really grasp the geometry of

312
00:15:59,240 --> 00:16:01,960
this because it's the key to why this is so dangerous.

313
00:16:02,279 --> 00:16:07,799
Space is vast, it's incomprehensibly huge, and planets, even massive

314
00:16:07,879 --> 00:16:12,080
gas giants like Jupiter, are incredibly tiny targets when you

315
00:16:12,120 --> 00:16:15,120
were aiming at them from hundreds of millions of miles away.

316
00:16:15,159 --> 00:16:16,600
Speaker 2: It's like trying to hit a speck of dust with

317
00:16:16,639 --> 00:16:18,879
a laser pointer from across a football stadium.

318
00:16:18,960 --> 00:16:21,720
Speaker 1: Right, So, imagine a massive dish on Earth, say the

319
00:16:21,720 --> 00:16:25,399
one out in Goldstone, California. It fires a concentrated beam

320
00:16:25,440 --> 00:16:28,840
of data at Mars. Mars absorbs a tiny fraction of

321
00:16:28,879 --> 00:16:32,240
that signal. The rover recedes its instructions to drill into

322
00:16:32,320 --> 00:16:32,879
a rock.

323
00:16:32,759 --> 00:16:34,720
Speaker 2: But the rest of the signal doesn't just stop.

324
00:16:34,960 --> 00:16:38,559
Speaker 1: Exactly. The vast fast majority of that powerful transmission doesn't

325
00:16:38,600 --> 00:16:41,440
just stop at Mars. It spills right past the edges

326
00:16:41,440 --> 00:16:44,039
of the planet and keeps hurtling outward into deep space

327
00:16:44,039 --> 00:16:44,840
at the speed of light.

328
00:16:44,919 --> 00:16:46,200
Speaker 2: It's unavoidable physics.

329
00:16:46,360 --> 00:16:48,240
Speaker 1: I was trying to think of a way to visualize

330
00:16:48,240 --> 00:16:50,879
this earlier, and initially I thought it was like using

331
00:16:50,960 --> 00:16:53,440
a sniper laser sight and painting a target on the

332
00:16:53,480 --> 00:16:56,759
wall behind your actual target. But that's not quite right

333
00:16:56,840 --> 00:17:00,279
because a laser is narrow. A better analogy it would

334
00:17:00,279 --> 00:17:02,639
be standing in the middle of the Grand Canyon at

335
00:17:02,720 --> 00:17:03,679
pitch black night.

336
00:17:04,400 --> 00:17:05,559
Speaker 2: Okay, I'm picturing it.

337
00:17:05,920 --> 00:17:08,200
Speaker 1: You have a friend standing on a ridge a mile away.

338
00:17:08,880 --> 00:17:10,440
You want to tell them something, but you don't want

339
00:17:10,440 --> 00:17:13,240
anyone else to hear. But the only tool you have

340
00:17:13,880 --> 00:17:18,240
is an incredibly powerful military grade bullhorn. Oh wow, You

341
00:17:18,279 --> 00:17:20,640
point the bullhorn at your friend and yell your message.

342
00:17:20,759 --> 00:17:23,880
Your friend hears you, sure, but the acoustic energy of

343
00:17:23,920 --> 00:17:26,960
your voice, that focus blast of sound blows right past

344
00:17:27,000 --> 00:17:30,519
your friend, bounces down the canyon walls and echoes for

345
00:17:30,640 --> 00:17:34,960
fifty miles, waking up every single predator, camper, and animal

346
00:17:35,039 --> 00:17:36,240
in the entire valley.

347
00:17:36,319 --> 00:17:39,400
Speaker 2: That is a brilliant refinement of the analogy. It perfectly

348
00:17:39,400 --> 00:17:43,720
captures the concept of spillover. We have been routinely firing

349
00:17:43,759 --> 00:17:46,640
off these high powered commands into the void for decades,

350
00:17:46,960 --> 00:17:50,119
heavily focused on the operational success of the mission, with

351
00:17:50,359 --> 00:17:53,519
very little consideration for what lies beyond the intended target.

352
00:17:53,319 --> 00:17:55,559
Speaker 1: Because we just assume it's empty space out there.

353
00:17:56,160 --> 00:17:59,640
Speaker 2: But it's not empty. And recent astrophysical studies mapping the

354
00:17:59,680 --> 00:18:03,880
trajectories of these transmissions have uncovered in a chilling geometric reality.

355
00:18:04,400 --> 00:18:06,880
If you trace the path of our most frequent deep

356
00:18:06,920 --> 00:18:10,839
space communications, they follow the orbital plane of our solar system,

357
00:18:11,039 --> 00:18:12,200
the ecliptic.

358
00:18:11,880 --> 00:18:15,640
Speaker 1: Because naturally that is where all of our planets, moons,

359
00:18:15,720 --> 00:18:18,599
and the probes we send to them reside right.

360
00:18:18,480 --> 00:18:21,319
Speaker 2: So all of our loudest, most focused shouting is happening

361
00:18:21,359 --> 00:18:25,319
on a very flat plane. And if an extraterrestrial civilization

362
00:18:25,400 --> 00:18:28,279
happens to reside in a star system that is aligned

363
00:18:28,279 --> 00:18:29,799
along that specific plane, if.

364
00:18:29,720 --> 00:18:33,480
Speaker 1: They are situated behind Mars or Jupiter relative to Earth

365
00:18:33,680 --> 00:18:35,680
during our transmission windows.

366
00:18:35,359 --> 00:18:38,359
Speaker 2: They're sitting directly in the crosshirs of humanity's most powerful

367
00:18:38,440 --> 00:18:39,079
data streams.

368
00:18:39,160 --> 00:18:42,000
Speaker 1: They are getting the full blast of the bullhorn precisely.

369
00:18:42,440 --> 00:18:45,640
Speaker 2: Researchers have actually mapped the background stars that fall into

370
00:18:45,680 --> 00:18:48,839
these billover zones, and they've calculated that observers aligned with

371
00:18:48,880 --> 00:18:52,160
the Earth Mars or Earth Jupiter axis during these command

372
00:18:52,240 --> 00:18:56,400
windows have a massive statistical probability of intercepting our signal.

373
00:18:56,640 --> 00:18:59,799
Speaker 1: And the terrifying implication here goes back to the nature

374
00:18:59,799 --> 00:19:04,759
of the signal itself. If an alien intelligence intercepts Ambiyet radar,

375
00:19:05,200 --> 00:19:07,279
they learn we have machines.

376
00:19:07,359 --> 00:19:10,720
Speaker 2: Right, But if they intercept this deep space spillover, they

377
00:19:10,720 --> 00:19:15,480
aren't getting faint, garbled static. They are intercepting high density,

378
00:19:15,720 --> 00:19:20,839
heavily structured data. They are catching targeted, high gain telemetry streams.

379
00:19:20,960 --> 00:19:23,920
Speaker 1: What does that actually mean for them? High gain telemetry like,

380
00:19:23,960 --> 00:19:24,799
what are they seeing?

381
00:19:24,960 --> 00:19:28,400
Speaker 2: It means we're handing them the keys to our technological castle.

382
00:19:28,759 --> 00:19:33,720
Telemetry contains complex mathematical encoding, error correction algorithms, and highly

383
00:19:33,799 --> 00:19:34,880
organized packet.

384
00:19:34,599 --> 00:19:37,000
Speaker 1: Structures, so it's obviously artificial.

385
00:19:36,599 --> 00:19:39,400
Speaker 2: Beyond obvious. Even if they cannot read the specific code,

386
00:19:39,519 --> 00:19:41,559
like if they don't know what's a command to move

387
00:19:41,559 --> 00:19:44,839
a robotic arm on a Mars rover, the mathematical architecture

388
00:19:44,839 --> 00:19:46,960
of the signal proves our level of computing power.

389
00:19:47,039 --> 00:19:50,960
Speaker 1: We are handing them our exact spatial coordinates, yes, and.

390
00:19:50,960 --> 00:19:55,440
Speaker 2: We are demonstrating our specific technical sophistication. Every single time

391
00:19:55,480 --> 00:19:59,480
we update a rover software. We cast this dense technological

392
00:19:59,519 --> 00:20:03,720
shadow cross thousands of light years, providing any listening intelligence

393
00:20:04,160 --> 00:20:08,039
with a highly detailed profile of the species pulling the strings.

394
00:20:08,240 --> 00:20:11,240
Speaker 1: We are basically mailing our resume to the universe and

395
00:20:11,279 --> 00:20:14,559
showing them exactly how smart we are, which unfortunately also

396
00:20:14,680 --> 00:20:16,680
shows them exactly what our limitations are.

397
00:20:16,799 --> 00:20:19,759
Speaker 2: It's a massive security risk, hypothetically.

398
00:20:19,160 --> 00:20:21,599
Speaker 1: Speaking, Now, let me push back on this a little bit,

399
00:20:21,720 --> 00:20:24,319
or at least play Devil's advocate regarding the next major

400
00:20:24,359 --> 00:20:28,480
technology the sources highlight planetary radar. Because with the deep

401
00:20:28,519 --> 00:20:31,880
space network, we are talking to our own probes. It's logistical.

402
00:20:32,160 --> 00:20:35,160
But with planetary radar, we are talking about planetary defense.

403
00:20:35,279 --> 00:20:38,680
Speaker 2: This is a very complex ethical and scientific debate. Yes, right.

404
00:20:39,079 --> 00:20:43,680
Speaker 1: Historically astronomers used massive fixed dish facilities, most famously the

405
00:20:43,720 --> 00:20:48,400
Arecibo Observatory in Puerto Rico before its unfortunate collapse, to

406
00:20:48,559 --> 00:20:53,359
fire incredibly concentrated blasts of microwave energy directly at near

407
00:20:53,400 --> 00:20:57,279
Earth asteroids to map them exactly, and from a human perspective,

408
00:20:57,319 --> 00:21:01,160
we have to do this right, It's a fundamental survival mechanism.

409
00:21:01,480 --> 00:21:04,039
We have a dark universe full of giant rocks that

410
00:21:04,079 --> 00:21:05,960
could literally wipe out our species.

411
00:21:06,039 --> 00:21:08,799
Speaker 2: So we fire a blast of energy at rock. We

412
00:21:08,960 --> 00:21:12,480
catch the unimaginably faint reflection that bounces back, and we

413
00:21:12,599 --> 00:21:14,960
calculate its trajectory to figure out if it's going to

414
00:21:15,039 --> 00:21:15,359
hit us.

415
00:21:15,759 --> 00:21:17,559
Speaker 1: We need to know if an asteroid is coming. It

416
00:21:17,599 --> 00:21:20,720
seems entirely justified. How is this a bad thing?

417
00:21:21,039 --> 00:21:25,440
Speaker 2: It is absolutely justified from a localized, short term survival standpoint.

418
00:21:25,799 --> 00:21:29,880
No serious astronomer or planetary scientists is suggesting we should

419
00:21:29,920 --> 00:21:32,400
just remain blind to hazardous near Earth objects.

420
00:21:32,480 --> 00:21:33,720
Speaker 1: Okay, good, but we have.

421
00:21:33,720 --> 00:21:38,119
Speaker 2: To intellectually acknowledge the terrifying paradox this survival mechanism creates

422
00:21:38,240 --> 00:21:41,079
to bounce a radio signal off a relatively tiny, non

423
00:21:41,119 --> 00:21:44,640
reflective rock millions of miles away and still be able

424
00:21:44,680 --> 00:21:47,599
to detect the microscopic echo that returns to Earth. The

425
00:21:47,640 --> 00:21:49,960
initial output of energy must be staggering.

426
00:21:50,039 --> 00:21:50,920
Speaker 1: It's brute force.

427
00:21:50,960 --> 00:21:53,680
Speaker 2: Physic it is the definition of brute force. The concept

428
00:21:53,720 --> 00:21:58,319
is known as equivalent isotropic radiated power or EERP. It

429
00:21:58,359 --> 00:22:00,720
measures how bright a highly focused be would be if

430
00:22:00,720 --> 00:22:01,920
it were radiated in all.

431
00:22:01,720 --> 00:22:03,480
Speaker 1: Directions, and how bright is it.

432
00:22:03,880 --> 00:22:07,720
Speaker 2: When facilities like Recibo or the Goldstone Solar System radar

433
00:22:08,000 --> 00:22:11,720
fire their planetary radar beams, their EERP can reach into

434
00:22:11,759 --> 00:22:12,920
the tens of tarot.

435
00:22:12,599 --> 00:22:14,359
Speaker 1: Watters tens of terot.

436
00:22:14,079 --> 00:22:17,920
Speaker 2: For a brief moment during those specific radio frequencies, those

437
00:22:18,079 --> 00:22:22,240
localized dishes temporarily become the brightest radio objects in our

438
00:22:22,400 --> 00:22:26,559
entire solar system. In those specific narrow bands, they completely

439
00:22:26,559 --> 00:22:27,359
outshine the Sun.

440
00:22:27,519 --> 00:22:29,839
Speaker 1: I just want to pause on that because it's so counterintuitive,

441
00:22:29,880 --> 00:22:32,440
and antenna sitting in a jungle in Puerto Rico for

442
00:22:32,480 --> 00:22:35,599
a fraction of a second is brighter in radio waves

443
00:22:36,000 --> 00:22:40,039
than a massive million mile wide ball of fusing plasma.

444
00:22:40,119 --> 00:22:42,920
Speaker 2: That is the power of concentrated emission. And just like

445
00:22:42,960 --> 00:22:46,480
the deep space network spillover, the vast vast majority of

446
00:22:46,480 --> 00:22:50,200
that intense radar pulse misses the target asteroid completely.

447
00:22:50,240 --> 00:22:51,880
Speaker 1: It just grazes the rock and keeps going.

448
00:22:52,200 --> 00:22:56,880
Speaker 2: It continues outward into the galaxy like a blinding interstellar searchlight.

449
00:22:57,440 --> 00:23:01,720
These momentary bursts of energy represent Earth's absolute, most detectable,

450
00:23:01,759 --> 00:23:07,640
albeit accidental, techno signatures. Current calculations suggest that a massive

451
00:23:07,680 --> 00:23:11,599
planetary radar paying could be detected by a civilization possessing

452
00:23:11,680 --> 00:23:15,119
only our current level of technology from up to twelve

453
00:23:15,160 --> 00:23:16,359
thousand light years away.

454
00:23:16,480 --> 00:23:19,519
Speaker 1: Wait, twelve thousand light years, Yes, that isn't just our

455
00:23:19,559 --> 00:23:23,559
local neighborhood that encompasses millions of star systems. A massive

456
00:23:23,599 --> 00:23:26,400
swave of the Milky Way galaxy essentially just got flash

457
00:23:26,440 --> 00:23:29,599
banged by humanity's attempt to look at a space rock.

458
00:23:29,559 --> 00:23:33,000
Speaker 2: Exactly, And this leads us to a deeply profound question

459
00:23:33,039 --> 00:23:38,599
about survival in a potentially hostile universe. We fired these loudest,

460
00:23:38,640 --> 00:23:41,359
most undeniable warning shots into the dark, not to announce

461
00:23:41,359 --> 00:23:43,359
our presence but to see what was immediately in front

462
00:23:43,359 --> 00:23:43,640
of us.

463
00:23:43,799 --> 00:23:47,920
Speaker 1: But an alien intelligence detecting these momentary, blinding flashes of

464
00:23:47,920 --> 00:23:50,400
microwave radiation wouldn't know our intentions.

465
00:23:50,440 --> 00:23:52,440
Speaker 2: They wouldn't know there was an asteroid involved at all.

466
00:23:52,839 --> 00:23:56,279
All they would see is an emerging civilization violently flexing

467
00:23:56,359 --> 00:23:58,359
a massive technological capability.

468
00:23:58,680 --> 00:24:01,640
Speaker 1: If we return to the opening analogy of the dark forest,

469
00:24:02,160 --> 00:24:04,759
if the ultimate truth of the cosmos is that hiding

470
00:24:04,839 --> 00:24:08,440
is the only viable survival strategy, our desperate attempts to

471
00:24:08,480 --> 00:24:11,640
look out for local danger might be the exact mechanism

472
00:24:11,720 --> 00:24:16,440
that draws a much larger interstellar danger directly to our doorstep.

473
00:24:16,680 --> 00:24:21,480
Speaker 2: We are waving the highest powered flashlight imaginable, completely ignoring

474
00:24:21,559 --> 00:24:23,720
how far the beam travels through the trees.

475
00:24:23,960 --> 00:24:27,319
Speaker 1: It's the ultimate double edged sword. To survive the rocks,

476
00:24:27,359 --> 00:24:30,039
we have to look. But by looking, we make ourselves

477
00:24:30,079 --> 00:24:33,519
the most visible target in the galaxy. Okay, so invisible

478
00:24:33,599 --> 00:24:37,039
radio waves, deep space telemetry, and radar blasts are our

479
00:24:37,160 --> 00:24:40,960
loudest acoustic alarms, so to speak. But they aren't the

480
00:24:40,960 --> 00:24:43,079
only way to spot a civilization, not at all.

481
00:24:43,079 --> 00:24:44,680
Speaker 2: They might not even be listening to radio.

482
00:24:44,880 --> 00:24:48,000
Speaker 1: Right What if a quiet patient observer doesn't even bother

483
00:24:48,079 --> 00:24:51,319
building massive radio telescopes. What if they aren't listening for

484
00:24:51,400 --> 00:24:53,599
our radar pings. What if they just look through a

485
00:24:53,680 --> 00:24:56,319
lens at the literal chemical makeup of the air we

486
00:24:56,400 --> 00:24:56,880
are breathing.

487
00:24:57,000 --> 00:24:59,039
Speaker 2: This is a completely different category of leakage.

488
00:24:59,160 --> 00:25:01,519
Speaker 1: It forces us to to look at the chemical fingerprint

489
00:25:01,559 --> 00:25:05,640
of a reckless species. We are talking about atmospheric industrial

490
00:25:05,680 --> 00:25:09,680
smog and artificial greenhouse gases. Let's start with the smog,

491
00:25:10,000 --> 00:25:12,400
specifically nitrogen dioxide or anotio.

492
00:25:13,160 --> 00:25:15,599
Speaker 2: To understand why this is so critical, we need to

493
00:25:15,680 --> 00:25:20,119
understand how astronomers study distant planets. They use spectroscopy. When

494
00:25:20,160 --> 00:25:22,559
a planet passes in front of its host star, the

495
00:25:22,599 --> 00:25:25,799
starlight filters through the planet's atmosphere.

496
00:25:25,119 --> 00:25:27,680
Speaker 1: And different chemicals block different colors of light.

497
00:25:27,799 --> 00:25:32,880
Speaker 2: Right, Yes, different chemical elements and molecules absorb specific wavelengths

498
00:25:32,960 --> 00:25:36,440
or colors of that starlight. By analyzing the light that

499
00:25:36,480 --> 00:25:40,039
finally reaches our telescopes, we can see black lines missing

500
00:25:40,039 --> 00:25:43,599
gaps in the spectrum, which act exactly like a chemical barcode.

501
00:25:43,920 --> 00:25:47,279
Speaker 1: Now, when human astronomers look for life on exoplanets, we

502
00:25:47,319 --> 00:25:50,559
primarily search for biosignatures. We look for the bar codes

503
00:25:50,559 --> 00:25:52,880
of oxygen or methane or water vapor.

504
00:25:52,559 --> 00:25:56,000
Speaker 2: Gases that indicate active biological respiration or organic decay.

505
00:25:56,279 --> 00:25:59,359
Speaker 1: But if an advanced alien civilization is searching for us,

506
00:25:59,519 --> 00:26:02,920
they wouldn't limit their search to mere biology. A planet

507
00:26:02,960 --> 00:26:05,880
with moss and bacteria is interesting, but a planet with

508
00:26:05,960 --> 00:26:09,400
machines is relevant. They would look for industry and.

509
00:26:09,440 --> 00:26:12,279
Speaker 2: Humanity is spent the entirety of the last two centuries

510
00:26:12,519 --> 00:26:17,480
pumping a very specific, highly visible advertisement of our industrial

511
00:26:17,519 --> 00:26:19,440
revolution directly into our atmosphere.

512
00:26:19,559 --> 00:26:22,839
Speaker 1: Nitrogen dioxide, the stuff that makes smog look brown over

513
00:26:22,839 --> 00:26:23,240
a city.

514
00:26:23,359 --> 00:26:26,640
Speaker 2: Yes, now, N two does occur naturally on Earth in

515
00:26:26,759 --> 00:26:30,160
very small quantities. A massive lightning storm can produce it,

516
00:26:30,279 --> 00:26:33,480
as concertain volcanic eruptions, But the vast majority of the

517
00:26:33,640 --> 00:26:37,079
N two currently enveloping our planet, roughly seventy six percent

518
00:26:37,119 --> 00:26:39,720
of it, is the direct result of high temperature combustion.

519
00:26:39,839 --> 00:26:42,279
Speaker 1: It is the exhaust from our coal fired power plants,

520
00:26:42,440 --> 00:26:46,119
our heavy manufacturing factories, and the billions of internal combustion

521
00:26:46,240 --> 00:26:48,799
engines powering ore cars, trucks, and ships.

522
00:26:49,240 --> 00:26:52,599
Speaker 2: So to an alien observer using a spectrometer to study Earth,

523
00:26:53,039 --> 00:26:56,720
this unnatural concentration of N two acts as a glaring anomaly.

524
00:26:57,279 --> 00:27:00,880
It absorbs specific wavelengths of visible light, curving a distinct,

525
00:27:00,880 --> 00:27:03,440
heavy barcode into the visual spectrum of our planet.

526
00:27:03,640 --> 00:27:07,880
Speaker 1: And the research suggests that an extraterrestrial civilization with a

527
00:27:07,920 --> 00:27:11,440
space telescope only moderately larger than our James Web space

528
00:27:11,480 --> 00:27:15,680
telescope could read that barcode, that unnatural No two smog

529
00:27:15,799 --> 00:27:18,160
layer from up to thirty light years away.

530
00:27:18,400 --> 00:27:22,240
Speaker 2: Thirty light years is a massive radius for direct atmospheric analysis.

531
00:27:22,279 --> 00:27:25,880
Speaker 1: It's essentially a massive chemical billboard painted across our sky

532
00:27:25,960 --> 00:27:28,160
that says, we burn stuff here.

533
00:27:28,079 --> 00:27:31,759
Speaker 2: We burn stuff here. Is a perfect summarization, and the

534
00:27:31,799 --> 00:27:35,559
implication of that specific barcode goes far beyond mere detection

535
00:27:36,079 --> 00:27:38,720
because it doesn't just announce that we exist. It tells

536
00:27:38,759 --> 00:27:42,200
a highly detailed story about our technological adolescence.

537
00:27:42,359 --> 00:27:44,599
Speaker 1: Technological adolescens. I love that phrasing.

538
00:27:44,920 --> 00:27:49,000
Speaker 2: If there are older, more advanced civilizations monitoring this sector

539
00:27:49,000 --> 00:27:51,400
of the galaxy, they wouldn't just see N two. They

540
00:27:51,440 --> 00:27:54,400
would understand what No. Two represents. It is a highly

541
00:27:54,480 --> 00:27:58,640
unstable molecule. It breaks down quickly when exposed to ultraviolet starlight.

542
00:27:58,880 --> 00:28:01,319
Speaker 1: OH, meaning it doesn't just ainger for millions of years.

543
00:28:01,640 --> 00:28:03,759
For the barcode to be there, we have to be

544
00:28:03,799 --> 00:28:05,319
actively creating it right now.

545
00:28:05,640 --> 00:28:10,480
Speaker 2: Precisely, the continuous presence of two means the combustion is ongoing.

546
00:28:11,200 --> 00:28:14,480
It marks us as a species in a very specific,

547
00:28:14,799 --> 00:28:18,359
highly volatile phase of development. We have unlocked the immense

548
00:28:18,400 --> 00:28:21,519
power of combustion and heavy industry, which means we are

549
00:28:21,559 --> 00:28:23,880
capable of altering our planetary environment.

550
00:28:24,200 --> 00:28:28,519
Speaker 1: But we haven't yet mastered clean efficient energy like widespread

551
00:28:28,640 --> 00:28:29,519
nuclear fusion.

552
00:28:29,640 --> 00:28:33,279
Speaker 2: Exactly, we haven't engineered ourselves out of our physical, messy

553
00:28:33,319 --> 00:28:34,720
reliance on fossil fuels.

554
00:28:34,799 --> 00:28:37,839
Speaker 1: We are the cosmic teenagers leaving empty soda cans and

555
00:28:37,880 --> 00:28:40,480
dirty laundry all over our room, and the whole neighborhood

556
00:28:40,519 --> 00:28:41,319
can smell it.

557
00:28:41,319 --> 00:28:45,079
Speaker 2: It is a very apt, if slightly humbling comparison. We

558
00:28:45,160 --> 00:28:48,200
are the most dangerous transition period of species can endure.

559
00:28:48,400 --> 00:28:51,960
We have the capability to create global environmental impacts, but

560
00:28:52,039 --> 00:28:55,000
we are still relying on primitive, dirty power generation.

561
00:28:55,440 --> 00:28:58,079
Speaker 1: By looking at the smog choking our major cities and

562
00:28:58,200 --> 00:29:01,880
alien intelligence wouldn't just locate us, they would instantly diagnose

563
00:29:01,920 --> 00:29:05,400
our exact stage of technological maturity. We are broadcasting our

564
00:29:05,440 --> 00:29:08,119
growing pains through the very pollution we struggle to breathe.

565
00:29:08,200 --> 00:29:10,200
Speaker 2: That is a staggering weight I view our own pollution,

566
00:29:10,720 --> 00:29:12,119
but it's scientifically accurate.

567
00:29:12,240 --> 00:29:14,759
Speaker 1: But the sources highlight that No. Two is only one

568
00:29:14,880 --> 00:29:17,400
part of our chemical footprint, and it actually has a

569
00:29:17,440 --> 00:29:20,200
slight ambiguity to it because, as you mentioned, lightning and

570
00:29:20,279 --> 00:29:24,359
volcanoes do make two. So an alien astronomer looking at

571
00:29:24,400 --> 00:29:27,680
our smog barcode might have a tiny shatter of a doubt.

572
00:29:27,839 --> 00:29:30,640
They might think, well, maybe Earth is just undergoing a

573
00:29:30,640 --> 00:29:32,480
period of hyperactive volcanism.

574
00:29:32,599 --> 00:29:34,920
Speaker 2: That is a fair scientific assumption for them to make.

575
00:29:35,279 --> 00:29:38,039
Speaker 1: But that shadow of doubt vanishes completely when we get

576
00:29:38,039 --> 00:29:44,400
to the second chemical signature, artificial greenhouse gases, specifically chlorofluorcarbons

577
00:29:44,480 --> 00:29:48,039
or CFCs. This part of the research completely shifted my

578
00:29:48,079 --> 00:29:51,000
perspective because while No. Two has a small natural excuse,

579
00:29:51,319 --> 00:29:55,200
CFCs have zero natural excuses. They simply do not exist.

580
00:29:54,880 --> 00:29:59,880
Speaker 2: In nature none whatsoever. Humanity manufactured these complex synthetic molecules

581
00:30:00,000 --> 00:30:03,519
starting in the early twentieth century, primarily for use in refrigeration,

582
00:30:03,680 --> 00:30:07,680
air conditioning systems and as propellants in aerosol cans like hairspray.

583
00:30:07,920 --> 00:30:09,960
Speaker 1: The chemistry is fascinating but destructive.

584
00:30:10,519 --> 00:30:14,240
Speaker 2: Yes, CFCs are incredibly stable in the lower atmosphere, which

585
00:30:14,240 --> 00:30:16,839
made them great for industry, but they are highly toxic

586
00:30:16,839 --> 00:30:21,200
to the stratospheric ozone layer. Because CFCs are entirely the

587
00:30:21,240 --> 00:30:25,480
product of laboratory synthesis, they represent the absolute holy grail

588
00:30:25,599 --> 00:30:29,319
of techno signatures for an observing astronomer. They are a

589
00:30:29,440 --> 00:30:33,359
chemical compound with a virtually zero percent false positive rate.

590
00:30:33,680 --> 00:30:36,440
Speaker 1: So if you are looking at a planet's atmospheric barcode

591
00:30:36,480 --> 00:30:39,200
and you see the lines for CFCs, you know with

592
00:30:39,599 --> 00:30:44,160
absolute one hundred percent certainty that a technological civilization synthesize them.

593
00:30:44,240 --> 00:30:47,559
Speaker 2: There are no CFC producing trees, there are no CFC volcanoes.

594
00:30:47,640 --> 00:30:50,920
Speaker 1: It is a permanent, undeniable neon sign that says intelligent

595
00:30:50,960 --> 00:30:51,599
life is here.

596
00:30:51,680 --> 00:30:55,200
Speaker 2: It removes all ambiguity. CFCs absorbed heavily in the thermal

597
00:30:55,319 --> 00:30:58,599
mid infrared spectrum. Now to explain why that matters, The

598
00:30:58,599 --> 00:31:01,359
Earth absorbs visible LFE and the Sun warms up and

599
00:31:01,480 --> 00:31:04,559
radiates that heat back out into space as infra red radiation.

600
00:31:04,720 --> 00:31:08,119
This normal planetary heat loss, right, But CSCs act like

601
00:31:08,160 --> 00:31:10,720
a microscopicy brick wall for that specific wave length of

602
00:31:10,720 --> 00:31:14,759
heat they trap it. This absorption creates a massive, undeniable

603
00:31:14,799 --> 00:31:18,039
spike in our atmospheric opacity in the mid interred range.

604
00:31:18,160 --> 00:31:22,119
Speaker 1: And even though humanity globally banded together in the nineteen

605
00:31:22,160 --> 00:31:25,400
eighties with the Montreal Protocol to ban the worst of

606
00:31:25,440 --> 00:31:28,599
the CFCs in order to save our ozone layer.

607
00:31:28,640 --> 00:31:32,240
Speaker 2: These molecules are so robust that the residual gases will

608
00:31:32,319 --> 00:31:36,119
linger in our atmosphere for centuries. That neon sign is

609
00:31:36,160 --> 00:31:39,359
going to keep flashing long after our factories stopped producing

610
00:31:39,359 --> 00:31:39,759
the gas.

611
00:31:39,799 --> 00:31:42,440
Speaker 1: But if we delve into the psychology and the strategic

612
00:31:42,640 --> 00:31:46,200
thinking of an advanced alien observer, this is where the

613
00:31:46,240 --> 00:31:50,720
detection of CFCs transitions from an interesting discovery to something

614
00:31:50,799 --> 00:31:51,880
truly unsettling.

615
00:31:52,000 --> 00:31:55,079
Speaker 2: Right, the research goes into why an advanced civilization might

616
00:31:55,160 --> 00:31:57,759
actively look for css, and it has nothing to do

617
00:31:57,799 --> 00:31:58,400
with hairspray.

618
00:31:58,519 --> 00:32:00,000
Speaker 1: Yeah, they don't care about our refrigeration.

619
00:32:00,240 --> 00:32:03,559
Speaker 2: To an advanced species, artificial greenhouse gases are tools of

620
00:32:03,559 --> 00:32:09,000
planetary engineering. If an advanced civilization finds a freezing dead world,

621
00:32:09,240 --> 00:32:13,279
bread perhaps a planet sitting just outside the habitable zone

622
00:32:13,319 --> 00:32:15,599
of its star, and they want to colonize it. How

623
00:32:15,640 --> 00:32:16,359
do they warm it up?

624
00:32:16,519 --> 00:32:20,160
Speaker 1: You pump it full of hyper efficient, highly stable artificial

625
00:32:20,200 --> 00:32:23,799
greenhouse gases like CFCs. It's a brilliant brute force way

626
00:32:23,839 --> 00:32:24,519
to terraform it.

627
00:32:24,759 --> 00:32:28,359
Speaker 2: Exactly. Yeah, you artificially thicken the blanket to trap the

628
00:32:28,400 --> 00:32:31,400
star's heat so liquid water can flow and life can survive.

629
00:32:31,480 --> 00:32:34,559
Speaker 1: But imagine the cognitive dissonance for that alien astronomer. They

630
00:32:34,599 --> 00:32:37,920
point their telescope at Earth, they calculate our orbit. They

631
00:32:38,000 --> 00:32:40,640
see that Earth is sitting perfectly in the habitable zone.

632
00:32:40,680 --> 00:32:47,119
Speaker 2: They see the biosignatures of a lush, water rich, thriving biosphere.

633
00:32:46,359 --> 00:32:49,160
Speaker 1: And then layered on top of that perfection, they see

634
00:32:49,200 --> 00:32:53,519
the massive, unmistakable signature of terraforming gases.

635
00:32:53,680 --> 00:32:55,480
Speaker 2: Oh wow, I see where this is going.

636
00:32:55,519 --> 00:32:57,680
Speaker 1: They would look at us and think, wait, why are

637
00:32:57,720 --> 00:33:01,799
they pumping extreme terraforming heat wrapping gases into a planet

638
00:33:01,880 --> 00:33:05,200
that is already biologically perfect? Are they intentionally trying to

639
00:33:05,240 --> 00:33:09,440
overheat their own biosphere? It makes us look completely insane.

640
00:33:09,559 --> 00:33:15,359
Speaker 2: It makes us look deeply irrational, suspicious, and frankly dangerously reckless.

641
00:33:15,799 --> 00:33:19,079
The chemical signature we accidentally leaked through old refrigerators and

642
00:33:19,160 --> 00:33:23,519
discarded aerosol cans paints a terrifying psychological profile.

643
00:33:23,200 --> 00:33:23,720
Speaker 1: Really does.

644
00:33:23,960 --> 00:33:28,039
Speaker 2: It presents a picture of a technologically capable species that

645
00:33:28,160 --> 00:33:32,079
is recklessly tampering with a thermodynamic balance of a perfectly

646
00:33:32,119 --> 00:33:36,279
habitable world. It signals to the galaxy that we possess

647
00:33:36,359 --> 00:33:40,599
the industrial capacity to alter planets, but entirely lack the

648
00:33:40,640 --> 00:33:43,759
wisdom to manage the power we have unlocked.

649
00:33:43,759 --> 00:33:46,720
Speaker 1: Which, depending on the philosophy of whoever is watching, could

650
00:33:46,720 --> 00:33:49,200
mark us not just as a curiosity, but as an

651
00:33:49,200 --> 00:33:52,519
active threat, a chaotic species that might need to be

652
00:33:52,640 --> 00:33:55,640
quarantined or dealt with Before we spread our reckless industrial

653
00:33:55,640 --> 00:33:59,559
habits to other star systems. We are essentially advertising our

654
00:33:59,599 --> 00:34:00,599
own competence.

655
00:34:00,680 --> 00:34:01,680
Speaker 2: It's a sobering thought.

656
00:34:02,079 --> 00:34:04,920
Speaker 1: Okay, So, if our atmosphere is broadcasting that we are

657
00:34:04,960 --> 00:34:09,639
a messy, industrializing, potentially irrational species, what happens when they

658
00:34:09,639 --> 00:34:12,679
look past the atmospheric gases? What happens when they look

659
00:34:12,719 --> 00:34:14,920
at the actual physical structures we are building on the

660
00:34:14,960 --> 00:34:18,039
surface of our planet and in the immediate space surrounding it.

661
00:34:18,079 --> 00:34:19,519
Speaker 2: We become even more visible.

662
00:34:19,719 --> 00:34:21,920
Speaker 1: This brings us to a highly visual segment of our

663
00:34:21,960 --> 00:34:25,960
accidental broadcast, drawing the blinds and lighting the sky. Let's

664
00:34:26,000 --> 00:34:29,079
talk about our visual and orbital footprints, starting with night

665
00:34:29,159 --> 00:34:30,079
side city lights.

666
00:34:30,440 --> 00:34:34,119
Speaker 2: This is perhaps the most visually dramatic and rapid transformation

667
00:34:34,199 --> 00:34:36,559
of our planet's surface in its four and a half

668
00:34:36,639 --> 00:34:40,800
billion year history. For billions of years, the night side

669
00:34:40,800 --> 00:34:45,239
of Earth was completely fundamentally dark, just black. It was

670
00:34:45,280 --> 00:34:47,960
illuminated only by the faint silver albedo of the Moon,

671
00:34:48,639 --> 00:34:51,239
an occasional localized lightning storm, or the rare glow of

672
00:34:51,239 --> 00:34:54,280
a volcanic eruption. But in the span of less than

673
00:34:54,320 --> 00:34:57,079
a century and a half, an absolute blink of an eye.

674
00:34:57,119 --> 00:35:01,039
In geological time, humanity has completely re wired the visual

675
00:35:01,079 --> 00:35:02,239
signature of our world.

676
00:35:02,400 --> 00:35:06,320
Speaker 1: We have paved our continents with sprawling urban megacities and

677
00:35:06,400 --> 00:35:09,360
illuminated them with billions of artificial light sources.

678
00:35:09,440 --> 00:35:11,719
Speaker 2: You can see it in those famous composite images from

679
00:35:11,719 --> 00:35:15,280
the International Space Station. The outline of human civilization is

680
00:35:15,320 --> 00:35:18,440
literally drawn in glowing electrical grids against the blackness of

681
00:35:18,480 --> 00:35:19,039
the oceans.

682
00:35:19,320 --> 00:35:22,119
Speaker 1: You can trace the coastlines of the United States, the

683
00:35:22,159 --> 00:35:24,960
dense highways of Europe, the stark national borders in the

684
00:35:24,960 --> 00:35:28,039
Middle East and Asia. We have completely erased the night

685
00:35:28,639 --> 00:35:31,559
and the sources point out an amazing, highly trackable shift

686
00:35:31,599 --> 00:35:34,960
in the technology of that light. We aren't just emitting light,

687
00:35:35,360 --> 00:35:38,440
we are dynamically changing its color signature over time.

688
00:35:38,719 --> 00:35:41,199
Speaker 2: This is a huge factor for external observation.

689
00:35:41,440 --> 00:35:44,400
Speaker 1: For decades, the majority of our streets and highways were

690
00:35:44,440 --> 00:35:48,199
bathed in the yellow orange glow of high pressure sodium lamps.

691
00:35:48,559 --> 00:35:51,239
And the sources note that a massive global emission of

692
00:35:51,360 --> 00:35:55,280
monochromatic sodium light is virtually impossible to produce naturally on

693
00:35:55,320 --> 00:35:56,280
a planetary scale.

694
00:35:56,400 --> 00:35:57,440
Speaker 2: Right major doesn't do that.

695
00:35:57,719 --> 00:36:00,320
Speaker 1: But over the last ten years we have been actively

696
00:36:00,440 --> 00:36:03,239
ripping out those sodium lamps and switching everything to highly

697
00:36:03,280 --> 00:36:04,639
efficient LEDs.

698
00:36:04,360 --> 00:36:07,400
Speaker 2: And that transition is highly visible and highly diagnostic to

699
00:36:07,440 --> 00:36:11,159
an external observer. We went from the distinct yellow orange

700
00:36:11,159 --> 00:36:15,039
spectrum of sodium vapor to a sharp, broad spectrum blue

701
00:36:15,039 --> 00:36:18,039
white peak that characterizes LED technology.

702
00:36:18,400 --> 00:36:22,519
Speaker 1: That blue white peak absolutely screams artificial engineering. It does

703
00:36:22,559 --> 00:36:25,599
not mimic starlight, it does not mimic fire. We are

704
00:36:25,679 --> 00:36:29,800
essentially blinking a complex, color coded message into space every

705
00:36:29,800 --> 00:36:31,400
twenty four hours as the Earth turns.

706
00:36:31,599 --> 00:36:34,800
Speaker 2: If a civilization has been passively monitoring our solar system

707
00:36:34,840 --> 00:36:39,000
for the last thousand years. The sudden explosive appearance of

708
00:36:39,119 --> 00:36:42,760
night side illumination over the last century is the ultimate

709
00:36:42,840 --> 00:36:46,159
dead giveaway of rapid exponential technological expansion.

710
00:36:47,159 --> 00:36:50,360
Speaker 1: It proves definitively that we have mastered electricity, that we

711
00:36:50,400 --> 00:36:54,559
have overcome the natural diurnal cycle of our biology, and

712
00:36:54,599 --> 00:36:58,239
that we have established massive, permanent, resource hungry settlements.

713
00:36:58,480 --> 00:37:01,559
Speaker 2: But there is a massive strategy vulnerability hidden in those

714
00:37:01,599 --> 00:37:03,320
beautiful glowing maps, isn't there.

715
00:37:03,440 --> 00:37:04,880
Speaker 1: Yeah, when I was reading this part, I got an

716
00:37:04,880 --> 00:37:05,599
absolute chill.

717
00:37:06,039 --> 00:37:09,880
Speaker 2: It is a profound vulnerability. Yes. By illuminating our cities

718
00:37:09,880 --> 00:37:12,519
so brightly, we aren't just announcing that we have electricity.

719
00:37:12,840 --> 00:37:16,800
We have conveniently and precisely highlighted our most densely populated

720
00:37:16,840 --> 00:37:19,199
areas with billions of watts of light.

721
00:37:19,599 --> 00:37:25,760
Speaker 1: We are handing any potential interstellar threat a perfect, highly illuminated,

722
00:37:25,840 --> 00:37:30,599
topographically accurate map of our most vital and vulnerable infrastructure centers.

723
00:37:30,920 --> 00:37:34,239
Speaker 2: Any hostile intelligence wouldn't need to guess where our population

724
00:37:34,360 --> 00:37:37,360
is concentrated. They wouldn't need to scout where our industrial

725
00:37:37,400 --> 00:37:41,639
capacity or political capitals lie. We have drawn a glowing blue,

726
00:37:41,679 --> 00:37:44,719
white bulls eye around every major city on Earth.

727
00:37:44,599 --> 00:37:47,280
Speaker 1: In our localized attempt to conquer the darkness of our

728
00:37:47,320 --> 00:37:49,199
own world so we can drive at night and keep

729
00:37:49,239 --> 00:37:53,159
our stores open. We have brightly illuminated our soft underbelly

730
00:37:53,239 --> 00:37:56,480
for whatever might be watching from the unfathomable darkness of space.

731
00:37:56,679 --> 00:37:59,920
Speaker 2: Here we are target New York, target London, target Tokyo.

732
00:38:00,000 --> 00:38:03,760
So here are the exact coordinates of our highest population densities.

733
00:38:03,840 --> 00:38:06,719
Speaker 1: It's terrifying when you reframe it from a strategic perspective,

734
00:38:07,239 --> 00:38:09,320
but we aren't just altering the surface of the Earth.

735
00:38:09,679 --> 00:38:12,400
In the last few years, we have begun radically changing

736
00:38:12,480 --> 00:38:15,159
the space immediately around it. Let's look at the orbital

737
00:38:15,199 --> 00:38:17,000
mega constellations.

738
00:38:16,320 --> 00:38:18,599
Speaker 2: Ah yes, satellite swarms.

739
00:38:18,960 --> 00:38:22,239
Speaker 1: In the last decade, there has been this absolute explosion

740
00:38:22,360 --> 00:38:27,000
of thousands upon thousands of commercial communication satellites launched into

741
00:38:27,079 --> 00:38:31,280
low Earth orbit to provide global Internet access. I want

742
00:38:31,280 --> 00:38:33,400
to pause here and ask you to explain the mechanics

743
00:38:33,400 --> 00:38:37,400
of the transit method, because when human astronomers use telescopes

744
00:38:37,440 --> 00:38:40,440
like Tepler or James Webb to look for exoplanets, we

745
00:38:40,480 --> 00:38:42,079
don't actually see the planet right.

746
00:38:42,320 --> 00:38:44,920
Speaker 2: Usually know we watch for a tiny dip in a

747
00:38:44,960 --> 00:38:48,199
star's brightness as a planet passes in front of it.

748
00:38:48,199 --> 00:38:50,480
It's like measuring the shadow of a moth flying in

749
00:38:50,480 --> 00:38:51,760
front of a distant street light.

750
00:38:52,079 --> 00:38:54,719
Speaker 1: Are our new satellite swarms actually messing up our own

751
00:38:54,760 --> 00:38:55,519
transit shadow?

752
00:38:55,679 --> 00:38:58,639
Speaker 2: They absolutely are, and it represents a monumental shift in

753
00:38:58,679 --> 00:39:01,920
how Earth presents itself of the wider galaxy. To explain

754
00:39:01,960 --> 00:39:05,000
the transit method, simply imagine staring at a bright light

755
00:39:05,039 --> 00:39:07,559
bulb from a mile away. You can't see a speck

756
00:39:07,599 --> 00:39:10,239
of dust circling the bulb, But if that speck passes

757
00:39:10,280 --> 00:39:12,719
directly between your eye and the bulb, the total amount

758
00:39:12,760 --> 00:39:15,320
of light hitting your eye drops by a microscopic fraction

759
00:39:15,360 --> 00:39:16,239
of a percent.

760
00:39:16,239 --> 00:39:18,800
Speaker 1: And by graphing that tiny dip in light over time,

761
00:39:19,280 --> 00:39:21,400
astronomers create a light curve.

762
00:39:21,760 --> 00:39:27,679
Speaker 2: A natural, rocky planet with an atmosphere produces a very smooth, predictable,

763
00:39:28,159 --> 00:39:31,639
uchased light curve as a transits across the star. But

764
00:39:31,679 --> 00:39:33,960
we are currently in the process of building a highly

765
00:39:33,960 --> 00:39:37,199
reflective metallic exoskeleton around our planet.

766
00:39:37,320 --> 00:39:40,320
Speaker 1: So an alien civilization using the transit method to look

767
00:39:40,360 --> 00:39:43,480
at Earth today would no longer see that smooth, natural

768
00:39:43,559 --> 00:39:47,480
light curve as we deploy tens of thousands of flat, metallic,

769
00:39:47,599 --> 00:39:50,519
highly reflective satellites into orbit to blanket the globe in

770
00:39:50,559 --> 00:39:54,000
high speed connectivity. We are fundamentally altering our silhouette.

771
00:39:54,039 --> 00:39:56,960
Speaker 2: Because the thousands of metallic satellites block and scatter the

772
00:39:57,000 --> 00:39:59,840
sunlight differently than a smooth atmosphere.

773
00:39:59,320 --> 00:40:04,840
Speaker 1: Would exactly, a densely packed mega constellation creates an irregular, jagged, fuzzy,

774
00:40:04,880 --> 00:40:09,679
and mathematically unnatural transit signature. This swarm of artificial objects

775
00:40:09,719 --> 00:40:12,280
scatters the starlight in erratic way. Is that a natural

776
00:40:12,280 --> 00:40:15,280
atmosphere or even a system of natural moons or dust

777
00:40:15,400 --> 00:40:19,400
rings simply cannot replicate physically? The math of the shadow changes.

778
00:40:19,639 --> 00:40:22,000
Speaker 2: So when they look at our shadow passing across the sun,

779
00:40:22,119 --> 00:40:24,920
our shadow looks fuzzy, jagged, and metallic. What does that

780
00:40:24,960 --> 00:40:27,039
specific shadow tell them about our civilization?

781
00:40:27,400 --> 00:40:31,920
Speaker 1: It communicates an immense amount of data. It showcases an explosive,

782
00:40:32,039 --> 00:40:36,119
exponential phase of technological growth. The sudden appearance of a

783
00:40:36,159 --> 00:40:40,599
massive orbital swarm around a previously quiet, rocky planet is

784
00:40:40,639 --> 00:40:45,800
the undeniable fingerprint of a civilization achieving true space bearing status.

785
00:40:46,039 --> 00:40:48,920
Speaker 2: It tells them we have mastered orbital mechanics, that we

786
00:40:48,960 --> 00:40:52,880
have achieved mass production capabilities, and that we require global

787
00:40:52,920 --> 00:40:54,000
networking bandwidth.

788
00:40:54,039 --> 00:40:57,519
Speaker 1: But critically, it also reveals our severe limitations. It tells

789
00:40:57,559 --> 00:41:00,360
them that we are still entirely confined to a single planet.

790
00:41:00,960 --> 00:41:04,559
It shows that we are rapidly cluttering our immediate orbital environment,

791
00:41:04,880 --> 00:41:06,599
risking a cascading debris event.

792
00:41:06,719 --> 00:41:09,119
Speaker 2: And most importantly, it shows that our civilization is now

793
00:41:09,199 --> 00:41:14,360
highly dependent on fragile, exposed orbital infrastructure. We are simultaneously

794
00:41:14,400 --> 00:41:18,360
broadcasting our technological awakening and our immen's structural vulnerability.

795
00:41:18,440 --> 00:41:21,360
Speaker 1: We have forged this shiny new high tech armour around

796
00:41:21,360 --> 00:41:24,119
our planet, but we are completely trapped inside it. And

797
00:41:24,159 --> 00:41:27,039
if someone or something breaks the armor, our entire global

798
00:41:27,039 --> 00:41:29,559
communication network collapses. That is a sobering thought.

799
00:41:29,719 --> 00:41:30,239
Speaker 2: It really is.

800
00:41:30,480 --> 00:41:34,119
Speaker 1: Staying with this theme of light, optics and visibility, let's

801
00:41:34,119 --> 00:41:37,519
look at the next evolution in our technology, optical lasers

802
00:41:37,719 --> 00:41:41,159
and light sales. For the last century, radio waves were

803
00:41:41,159 --> 00:41:45,280
our primary method of communication, but humanity is shifting. We

804
00:41:45,320 --> 00:41:48,440
are moving toward optical technology because it can carry vastly

805
00:41:48,519 --> 00:41:49,199
more data.

806
00:41:49,280 --> 00:41:51,599
Speaker 2: We are beginning to use high powered lasers for deep

807
00:41:51,679 --> 00:41:56,119
space communications, setting intense invisible beams to orbiters around the

808
00:41:56,119 --> 00:41:57,360
Moon and Mars.

809
00:41:57,079 --> 00:42:00,440
Speaker 1: And beyond just communication There are highly funded and vicious

810
00:42:00,440 --> 00:42:03,239
projects currently being designed to use a rays of Diggawat

811
00:42:03,239 --> 00:42:07,079
class lasers to physically push microscopic light sales to neighboring

812
00:42:07,119 --> 00:42:09,119
star systems like Alpha Centauri.

813
00:42:09,440 --> 00:42:11,719
Speaker 2: If radio leak from an airport is a whisper in

814
00:42:11,760 --> 00:42:14,760
the dark and a planetary radar ping is a searchlight,

815
00:42:15,400 --> 00:42:18,199
using a gigwat laser to push a physical sale across

816
00:42:18,199 --> 00:42:21,679
the galaxy is like firing a cosmic flare gun directly

817
00:42:21,679 --> 00:42:23,159
into the eye of whoever's looking.

818
00:42:23,239 --> 00:42:26,880
Speaker 1: Isn't it cosmic flare gun is the perfect visualization. These

819
00:42:26,920 --> 00:42:31,639
optical technologies represent a massive thrilling leap in human capability,

820
00:42:31,880 --> 00:42:35,599
but they create an entirely new and incredibly dangerous mechanism

821
00:42:35,679 --> 00:42:39,280
to accidentally reveal our exact location and technological prowess.

822
00:42:39,599 --> 00:42:42,760
Speaker 2: To understand why lasers are so much more visible than

823
00:42:42,840 --> 00:42:46,239
radio broadcasts, we have to look at how energy dissipates

824
00:42:47,000 --> 00:42:50,719
radio waves obey the inverse square law. If you imagine

825
00:42:50,719 --> 00:42:53,159
a balloon and you draw a smiley face on it

826
00:42:53,199 --> 00:42:55,480
with a marker. As you blow the balloon up, the

827
00:42:55,519 --> 00:42:59,119
ink spreads out, stretches, and becomes fainter and fainter until

828
00:42:59,119 --> 00:43:00,000
you can barely see it.

829
00:43:00,079 --> 00:43:02,840
Speaker 1: That is how radio waves travel through space. Their energy

830
00:43:02,880 --> 00:43:06,199
dilutes as the sphere of the broadcast expand.

831
00:43:05,920 --> 00:43:07,960
Speaker 2: But a laser does not dilute in the same way.

832
00:43:08,400 --> 00:43:11,840
A laser is a tightly coherent beam of photons. It

833
00:43:11,920 --> 00:43:14,559
is like putting a solid sticker on the balloon. No

834
00:43:14,639 --> 00:43:18,119
matter how big the balloon gets, the sticker remains concentrated.

835
00:43:18,239 --> 00:43:21,199
Speaker 1: The energy stays tightly packed together over massive distances.

836
00:43:21,320 --> 00:43:23,880
Speaker 2: Yes, so if an alien civilization happens to be in

837
00:43:23,920 --> 00:43:25,760
the exact line of sight of one of our high

838
00:43:25,760 --> 00:43:29,039
powered optical communication beams or an array designed to push

839
00:43:29,079 --> 00:43:31,559
a light sale, the signal they receive would not be

840
00:43:31,599 --> 00:43:34,320
a faint whisper. It would be blindingly obvious to an

841
00:43:34,320 --> 00:43:36,280
extraterrestrial optical telescope.

842
00:43:36,320 --> 00:43:39,400
Speaker 1: Normally, from a distance, our sun looks like a standard, stable,

843
00:43:39,559 --> 00:43:42,880
yellow dwarf star. It emits a broad spectrum of light

844
00:43:43,000 --> 00:43:44,440
we call black body radiation.

845
00:43:44,920 --> 00:43:48,320
Speaker 2: But if one of our deep space lasers momentarily sweeps

846
00:43:48,360 --> 00:43:51,519
across an alien observer's field of view, our star would

847
00:43:51,519 --> 00:43:55,480
suddenly appear to flash with an impossibly intense monochromatic spike

848
00:43:55,519 --> 00:43:55,800
of light.

849
00:43:55,920 --> 00:43:59,280
Speaker 1: A monochromatic spike meaning all the light in that flash

850
00:43:59,519 --> 00:44:04,239
is exactly one specific color, one highly specific wavelength, and

851
00:44:04,440 --> 00:44:06,280
stars simply do not do that.

852
00:44:06,440 --> 00:44:10,000
Speaker 2: Stars cannot do that. A monochromatic spike of that magnitude

853
00:44:10,280 --> 00:44:14,559
is a universal hallmark of advanced optical engineering. The sheer

854
00:44:14,599 --> 00:44:17,039
physical power required to push a light sale to another

855
00:44:17,079 --> 00:44:20,280
star system at a fraction the speed of light means

856
00:44:20,280 --> 00:44:23,559
that the laser array firing it would outshine the entire Earth.

857
00:44:23,679 --> 00:44:26,519
Speaker 1: In fact, in that specific laser wavelength, the beam would

858
00:44:26,559 --> 00:44:29,719
outshine our entire Sun by orders of magnitude, So.

859
00:44:29,639 --> 00:44:33,159
Speaker 2: It completely removes any ambiguity about our existence. You can't

860
00:44:33,199 --> 00:44:36,920
look at a gigawaant monochromatic laser pulse that outshines a star,

861
00:44:37,320 --> 00:44:39,320
They go, that's just a weird natural pulsar or a

862
00:44:39,400 --> 00:44:40,000
dust cloud.

863
00:44:40,199 --> 00:44:43,960
Speaker 1: It forces the issue entirely. An ambient radio leak could

864
00:44:44,119 --> 00:44:47,880
theoretically be dismissed by cautious alien scientists as a bizarre,

865
00:44:48,239 --> 00:44:53,039
unexplained astrophysical anomaly if the data isn't perfectly clear. But

866
00:44:53,239 --> 00:44:57,480
a gigawat laser pulse at a highly specific singular wavelength

867
00:44:57,519 --> 00:45:00,920
can only mean one thing. Intelligent life, life possessing vast

868
00:45:01,000 --> 00:45:04,199
energy resources and significant orbital infrastructure.

869
00:45:04,760 --> 00:45:07,760
Speaker 2: In our well intentioned attempt to quietly explore the nearby

870
00:45:07,840 --> 00:45:13,440
stars with microscopic light sales, we risk casting an impossibly bright, undeniable,

871
00:45:13,719 --> 00:45:17,360
and highly targeted spotlight directly onto our own fragile planet.

872
00:45:17,480 --> 00:45:20,480
Speaker 1: We are lighting up our skies with high powered lasers.

873
00:45:20,519 --> 00:45:23,440
We are wrapping our planet in swarms of metallic satellites,

874
00:45:23,639 --> 00:45:26,159
and we are painting our continents with blue white LEDs.

875
00:45:26,679 --> 00:45:30,119
But ironically, as our visual and optical footprint is absolutely

876
00:45:30,199 --> 00:45:33,119
exploding into the cosmos, our oldest, most famous method of

877
00:45:33,159 --> 00:45:35,239
cosmic communication is quietly vanishing.

878
00:45:35,320 --> 00:45:37,599
Speaker 2: This brings us to our final point of exploration today

879
00:45:37,800 --> 00:45:40,000
and honestly the one that gave me the most profound

880
00:45:40,079 --> 00:45:42,880
existential chill when I was reviewing the research the temporal

881
00:45:42,920 --> 00:45:45,199
paradox or the disappearing Radio window.

882
00:45:45,559 --> 00:45:49,039
Speaker 1: Let's unpack the illusion of the radio window. For about

883
00:45:49,119 --> 00:45:53,719
seventy years, humanity has been transmitting massive omnidirectional radio and

884
00:45:53,800 --> 00:45:58,199
television signals into space. The sources paint this vivid picture

885
00:45:58,639 --> 00:46:02,360
of an ever growing sphere of radio waves expanding outward

886
00:46:02,440 --> 00:46:04,679
from Earth in all directions at the speed of light,

887
00:46:05,159 --> 00:46:07,760
constantly announcing humanity's presence to the void.

888
00:46:08,119 --> 00:46:10,840
Speaker 2: It is often referred to as the loud, leaky phase

889
00:46:10,840 --> 00:46:13,920
of a civilization, and from a human perspective, it seems

890
00:46:13,920 --> 00:46:16,679
like a very long time. Seventy years covers a massive

891
00:46:16,719 --> 00:46:19,039
chunk of our modern history, from the end of World

892
00:46:19,079 --> 00:46:21,400
War II, through the Cold War up to the dawn

893
00:46:21,440 --> 00:46:22,039
of the Internet.

894
00:46:22,079 --> 00:46:24,880
Speaker 1: But in cosmic terms, against the billions of years the

895
00:46:24,920 --> 00:46:28,119
galaxy has existed, seventy years is less than a heartbeat.

896
00:46:28,440 --> 00:46:32,000
It is a microscopic fraction of time. And the incredible

897
00:46:32,039 --> 00:46:34,800
realization astronomers are coming to is that our window is

898
00:46:34,840 --> 00:46:36,199
already closing.

899
00:46:36,159 --> 00:46:39,960
Speaker 2: Because we are fundamentally shifting the foundation of our technology.

900
00:46:40,199 --> 00:46:44,079
We are broadcasting huge, inefficient on the directional analog TV

901
00:46:44,199 --> 00:46:46,360
signals from massive terrestrial towers anymore.

902
00:46:46,519 --> 00:46:50,199
Speaker 1: We are transitioning our core communications to fiber optic cables

903
00:46:50,400 --> 00:46:53,360
buried deep underground or laid across the ocean floor. We

904
00:46:53,400 --> 00:46:57,199
are using tightly beamed satellite Internet exactly like the Mega

905
00:46:57,239 --> 00:47:00,599
constellations we just discussed, which beam data to directly down

906
00:47:00,599 --> 00:47:02,559
to the surface rather than out into space.

907
00:47:02,760 --> 00:47:06,400
Speaker 2: We are using encrypted digital streaming services instead of blasting

908
00:47:06,440 --> 00:47:10,519
high watted UHF waves. We are essentially drawing the blinds

909
00:47:10,519 --> 00:47:14,400
on our own radio emissions. From a radio perspective, Earth

910
00:47:14,480 --> 00:47:15,199
is going silent.

911
00:47:15,880 --> 00:47:20,119
Speaker 1: This rapid technological shift creates a terrifying paradigm for SETI,

912
00:47:20,639 --> 00:47:24,719
the search for extraterrestrial intelligence, and profoundly alters our understanding

913
00:47:24,800 --> 00:47:27,800
of our place in the universe. For decades, our entire

914
00:47:27,840 --> 00:47:30,400
search strategy has been predicated on the assumption that if

915
00:47:30,440 --> 00:47:33,880
aliens are out there, they must be broadcasting in radio frequencies,

916
00:47:34,039 --> 00:47:35,519
just like we did in the twentieth century.

917
00:47:35,599 --> 00:47:38,480
Speaker 2: We point our massive radio dishes at the sky, waiting

918
00:47:38,480 --> 00:47:41,760
to intercept their version of television shows or their ambient

919
00:47:41,840 --> 00:47:42,519
radar pings.

920
00:47:43,440 --> 00:47:46,599
Speaker 1: But our own history is currently proving that this foundational

921
00:47:46,639 --> 00:47:51,960
assumption might be entirely flawed. The loud, leaky radio phase

922
00:47:52,000 --> 00:47:55,800
of technological development is incredibly brief. It is a stepping stone.

923
00:47:56,440 --> 00:47:59,800
Speaker 2: If a civilization only leaks radio waves for seventy year

924
00:47:59,840 --> 00:48:02,760
eight eighty years before figuring out how to enclose their

925
00:48:02,840 --> 00:48:05,960
data in fiber optics, then they are only visible in

926
00:48:06,000 --> 00:48:08,920
the radio spectrum for a fraction of a microsecond of

927
00:48:08,960 --> 00:48:10,039
their planet's lifetime.

928
00:48:10,400 --> 00:48:14,599
Speaker 1: So if every technological civilization follows a similar developmental path,

929
00:48:14,679 --> 00:48:19,840
going from messy inefficient omnidirectional radio invention quickly transitioning to

930
00:48:19,920 --> 00:48:23,880
highly efficient directed communication or enclosed fiber optics where the

931
00:48:23,960 --> 00:48:26,719
light bounces around inside the glass and never escapes. Then

932
00:48:26,760 --> 00:48:30,400
the mathematical probability of two civilizations overlapping in their loud

933
00:48:30,440 --> 00:48:32,239
phase is basically zero.

934
00:48:32,480 --> 00:48:37,039
Speaker 2: The probability becomes vanishingly small. We are inadvertently proving through

935
00:48:37,079 --> 00:48:41,079
our own technological evolution that advanced civilizations don't stay loud

936
00:48:41,079 --> 00:48:43,719
for long. They quiet down very quickly as a natural

937
00:48:43,719 --> 00:48:45,360
byproduct of efficiency, And.

938
00:48:45,320 --> 00:48:48,480
Speaker 1: This leads us to a much darker philosophical point often

939
00:48:48,480 --> 00:48:52,199
discussed in relation to the Fermi paradox. Do these older

940
00:48:52,239 --> 00:48:57,000
advanced civilizations quiet down merely through the pursuit of technological efficiency,

941
00:48:57,039 --> 00:48:59,920
as we are doing with fiber optics, or is there

942
00:48:59,920 --> 00:49:04,239
a darker, more intentional, more terrified desire to hide once

943
00:49:04,280 --> 00:49:07,119
they realize the true nature of the universe.

944
00:49:06,880 --> 00:49:09,800
Speaker 2: Once the civilization matures enough to understand the dark forest,

945
00:49:10,320 --> 00:49:12,800
once they realize that the galaxy might be full of

946
00:49:12,840 --> 00:49:16,840
silent apex predators, do they actively and aggressively suppress their

947
00:49:16,840 --> 00:49:17,880
emissions to survive.

948
00:49:18,119 --> 00:49:20,400
Speaker 1: But here's the thing that really gets me. Here is

949
00:49:20,440 --> 00:49:23,519
the temporal paradox of the whole situation. We might be

950
00:49:23,599 --> 00:49:26,559
transitioning to fiber optics, we might be quieting down now,

951
00:49:26,960 --> 00:49:29,599
but that seventy light year wide bubble of our loud

952
00:49:29,599 --> 00:49:32,800
phase is already out there. It has left the station because.

953
00:49:32,559 --> 00:49:34,599
Speaker 2: It has been expanding in all directions for seventy years.

954
00:49:34,679 --> 00:49:37,039
It is now a sphere one hundred and forty light

955
00:49:37,119 --> 00:49:39,519
years in diameter, and it holds everything.

956
00:49:39,760 --> 00:49:43,199
Speaker 1: It holds our early pop culture, our news broadcasts, the

957
00:49:43,320 --> 00:49:47,480
radar signatures of our early wars, our intentional messages like

958
00:49:47,519 --> 00:49:51,679
the Acibo broadcast. It is currently washing over thousands of

959
00:49:51,719 --> 00:49:54,840
star systems right now as we speak, and we can

960
00:49:54,880 --> 00:49:56,480
never ever pull it back.

961
00:49:57,480 --> 00:50:00,920
Speaker 2: That is the immovable, unforgiving reality of the speed of light.

962
00:50:01,679 --> 00:50:04,760
We are quietly shutting the door on our own radio emissions.

963
00:50:04,960 --> 00:50:07,360
We are retreating into the safety of fiber optics and

964
00:50:07,400 --> 00:50:11,400
targeted lasers, but the damage from a visibility standpoint is

965
00:50:11,480 --> 00:50:12,360
already done.

966
00:50:12,440 --> 00:50:14,800
Speaker 1: The sphere of our existence is expanding at one hundred

967
00:50:14,800 --> 00:50:17,840
and eighty six thousand miles per second, completely indifferent to

968
00:50:17,880 --> 00:50:19,079
our current attempts itself.

969
00:50:19,360 --> 00:50:21,679
Speaker 2: Every single time we caught a commercial flight, every time

970
00:50:21,719 --> 00:50:24,599
we sent a text message over a sprawling four G network.

971
00:50:24,760 --> 00:50:27,360
Every time we cooled our homes with CFCs or mapped

972
00:50:27,400 --> 00:50:30,519
an incoming asteroid to protect ourselves, we were acting as

973
00:50:30,519 --> 00:50:32,519
an accidental cosmic megaphone.

974
00:50:32,639 --> 00:50:34,599
Speaker 1: And now we are plunging back into the safety of

975
00:50:34,719 --> 00:50:37,239
radio silence as a planet. But the echo is already

976
00:50:37,239 --> 00:50:38,480
out there, traveling forever.

977
00:50:38,840 --> 00:50:41,000
Speaker 2: If we returned to the scenario you painted at the

978
00:50:41,079 --> 00:50:44,360
very beginning of our exploration, the flashlight in the dark forest,

979
00:50:45,079 --> 00:50:48,800
it is as if humanity has finally realized that waving

980
00:50:48,840 --> 00:50:51,599
the bright flashlight around is inherently dangerous.

981
00:50:51,679 --> 00:50:54,639
Speaker 1: We have clicked the switch. We have turned the flashlight off.

982
00:50:55,119 --> 00:50:57,320
We are trying to be quiet again, relying on our

983
00:50:57,400 --> 00:50:59,320
enclosed fiber optic night vision.

984
00:50:59,719 --> 00:51:02,679
Speaker 2: But in the pitch black, silent forest to the universe,

985
00:51:02,920 --> 00:51:06,679
while waving that flashlight, humanity accidentally stepped on a massive

986
00:51:06,760 --> 00:51:10,679
dry twig. The snap of that twig, our seventy years

987
00:51:10,719 --> 00:51:15,559
of chaotic radio noise, our indestructible chemical CFC barcodes, our

988
00:51:15,679 --> 00:51:19,519
blinding momentary radar blasts is traveling outward through the trees.

989
00:51:19,880 --> 00:51:22,519
Speaker 1: Somewhere in the cosmos, something very old, very quiet, and

990
00:51:22,639 --> 00:51:25,119
very patient may have already heard the snap. They may

991
00:51:25,119 --> 00:51:27,519
have already received our signal. They may have already analyzed

992
00:51:27,519 --> 00:51:31,199
our atmospheric smog, mapped our glowing blue white coastal cities,

993
00:51:31,360 --> 00:51:33,320
and marked our exact planetary coordinates.

994
00:51:33,760 --> 00:51:36,000
Speaker 2: We turned off the flashlight, but the snap of the

995
00:51:36,039 --> 00:51:38,760
twig is already echoed into the deep woods. And all

996
00:51:38,800 --> 00:51:41,159
we can do now, trapped in our single, rocky world,

997
00:51:41,480 --> 00:51:42,679
is wait to see what hurt us.

998
00:51:43,000 --> 00:51:47,079
Speaker 1: That is man, that's just profoundly haunting. But it's exactly

999
00:51:47,159 --> 00:51:50,119
why we do these deep explorations, to pull ourselves out

1000
00:51:50,119 --> 00:51:53,079
of our daily routines and see our everyday world from

1001
00:51:53,119 --> 00:51:58,039
a completely different cosmic perspective, from the cell phone sitting

1002
00:51:58,079 --> 00:52:00,639
in your pocket, to the glow of your city streets

1003
00:52:00,679 --> 00:52:03,400
at night, to the way we track our airplanes. You

1004
00:52:03,440 --> 00:52:06,599
are an active part of humanity's accidental broadcast.

1005
00:52:06,840 --> 00:52:08,719
Speaker 2: It really changes how you look at a street lamp.

1006
00:52:08,800 --> 00:52:11,320
Speaker 1: It really does. So we want to hear directly from you.

1007
00:52:11,599 --> 00:52:15,000
We've covered a massive amount of conceptual ground today. We've

1008
00:52:15,039 --> 00:52:19,000
explored the two quadrillion watts of sweeping airport radar, the

1009
00:52:19,039 --> 00:52:22,880
geometric crosshairs and spillover of the deep space network, the

1010
00:52:23,000 --> 00:52:28,000
lingering undeniable neon signs of artificial CFCs, the glowing bullseyes

1011
00:52:28,079 --> 00:52:31,239
of our led city grids, and the blinding sun out

1012
00:52:31,280 --> 00:52:33,599
shining flashes of our planetary defense radar.

1013
00:52:33,719 --> 00:52:34,800
Speaker 2: So many ways to be seen.

1014
00:52:34,880 --> 00:52:37,559
Speaker 1: If you had a cosmic mute button and you could

1015
00:52:37,559 --> 00:52:40,679
instantly and permanently erase just one of these accidental beacons

1016
00:52:40,719 --> 00:52:43,639
from existence to protect Earth from whatever might be listening

1017
00:52:43,719 --> 00:52:46,119
in the dark forest. Which one would you choose to

1018
00:52:46,119 --> 00:52:47,199
silence and why?

1019
00:52:47,400 --> 00:52:48,239
Speaker 2: That's great question.

1020
00:52:48,639 --> 00:52:51,360
Speaker 1: Leave a commet below with your answer and your reasoning.

1021
00:52:51,880 --> 00:52:54,800
Would you shut down the radar and risk the asteroids?

1022
00:52:55,119 --> 00:52:57,360
Would you turn off the city lights and plunge us

1023
00:52:57,400 --> 00:52:59,920
back into the dark. Would you hide the Mega constellation?

1024
00:53:00,599 --> 00:53:03,480
We cannot wait to read your thoughts and debate your strategies.

1025
00:53:03,960 --> 00:53:06,159
