1
00:00:00,040 --> 00:00:02,839
Speaker 1: I want you to try something for me mentally, I mean, okay,

2
00:00:03,120 --> 00:00:05,839
put yourself in the middle of the Atacoma Desert in Chile,

3
00:00:06,440 --> 00:00:11,560
high altitude, zero humidity, absolutely no light pollution. It is midnight.

4
00:00:11,800 --> 00:00:14,880
Speaker 2: You look up and you see the core of the galaxy.

5
00:00:15,240 --> 00:00:18,160
Speaker 1: You see that dense band of milk spilled across the sky,

6
00:00:18,879 --> 00:00:21,600
thousands of stars visible to the naked eye. The sheer

7
00:00:21,679 --> 00:00:24,800
scale of it just hits you in the chest. And

8
00:00:24,879 --> 00:00:28,359
the feeling you get usually it's awe It's this sense

9
00:00:28,399 --> 00:00:31,920
of peace, or maybe a comforting sort of insignificance. It

10
00:00:32,079 --> 00:00:34,119
feels pristine.

11
00:00:34,280 --> 00:00:38,200
Speaker 2: It feels natural, like a vast, untouched wilderness waiting to

12
00:00:38,240 --> 00:00:38,880
be explored.

13
00:00:39,079 --> 00:00:41,840
Speaker 1: Exactly. But here's why we are here today. You have

14
00:00:41,880 --> 00:00:44,679
brought a stack of papers, academic papers, not sci fi

15
00:00:44,719 --> 00:00:48,520
novels that suggests that feeling of pristine wilderness.

16
00:00:47,960 --> 00:00:50,840
Speaker 2: Is a lie, or at the very least, a massive

17
00:00:50,920 --> 00:00:54,759
statistical anomaly that we are misinterpreting, a deception, a really

18
00:00:54,840 --> 00:00:57,159
dangerous one. When I look at that sky, based on

19
00:00:57,159 --> 00:00:59,399
the data we're covering today, I don't see a wilderness.

20
00:00:59,479 --> 00:01:01,600
I see a great or maybe a waiting room.

21
00:01:01,679 --> 00:01:04,719
Speaker 1: Welcome to thrilling threads. Today we are stripping away the

22
00:01:04,760 --> 00:01:06,519
optimism from the Fermi paradox.

23
00:01:06,840 --> 00:01:09,920
Speaker 2: We usually do the Star Trek version of this conversation. Yeah,

24
00:01:09,959 --> 00:01:10,359
you know the one.

25
00:01:10,439 --> 00:01:11,239
Speaker 1: Oh, I know, the one.

26
00:01:11,120 --> 00:01:15,040
Speaker 2: Whereas everybody maybe they're prime directive observers, maybe they're shy.

27
00:01:14,799 --> 00:01:16,400
Speaker 1: Maybe they're just around the corner.

28
00:01:16,120 --> 00:01:18,000
Speaker 2: Maybe they just haven't invented warp drive yet.

29
00:01:18,079 --> 00:01:20,079
Speaker 1: We love those theories because they allow us to be

30
00:01:20,120 --> 00:01:23,159
the protagonist. They center us. But the research we are

31
00:01:23,239 --> 00:01:28,000
unpacking today six specific scenarios based on game theory, thermodynamics,

32
00:01:28,040 --> 00:01:31,079
and cosmological data. It doesn't care about our narrative.

33
00:01:31,280 --> 00:01:36,680
Speaker 2: No, these are the great silence scenarios that are mathematically

34
00:01:36,719 --> 00:01:42,439
consistent but existentially horrifying. We're talking about tsunamis of civilization,

35
00:01:42,760 --> 00:01:45,879
sleeping giants, and the physics of why the universe might

36
00:01:45,920 --> 00:01:47,280
be actively hiding from us.

37
00:01:47,400 --> 00:01:49,640
Speaker 1: The mission for this session of Thrilling Threads is to

38
00:01:49,680 --> 00:01:51,799
look at the silence not as a lack of evidence,

39
00:01:51,840 --> 00:01:53,680
but as evidence of something terrible.

40
00:01:53,799 --> 00:01:56,400
Speaker 2: The silence is data. We just don't like what it's saying.

41
00:01:56,519 --> 00:01:58,840
Speaker 1: So let's start with the first piece of evidence. You've

42
00:01:58,879 --> 00:02:01,280
brought a twenty twenty one paper by Robin Hanson and

43
00:02:01,319 --> 00:02:04,439
his team at George Mason University. This is the Grabby

44
00:02:04,519 --> 00:02:09,439
Aliens model. Now, Graby sounds cute like a toddler. I'm

45
00:02:09,520 --> 00:02:10,840
guessing the math isn't cute.

46
00:02:10,919 --> 00:02:14,000
Speaker 2: It is definitely not cute. Hanson is an economist and

47
00:02:14,039 --> 00:02:18,360
a futurist, and that's key. He applies statistical modeling to

48
00:02:18,439 --> 00:02:21,199
civilization growth from an economic.

49
00:02:20,879 --> 00:02:23,719
Speaker 1: Perspective, which is a different angle, a very different angle.

50
00:02:24,400 --> 00:02:29,719
Speaker 2: The core premise challenges a fundamental assumption we've had for decades. Yeah,

51
00:02:29,759 --> 00:02:34,560
that civilizations are random occurrences, scattered like towns on a map.

52
00:02:34,439 --> 00:02:37,639
Speaker 1: Which is the standard view. Right. We think space is big,

53
00:02:37,840 --> 00:02:40,840
so there's probably a civilization here and another one one

54
00:02:40,840 --> 00:02:43,360
million light years that way, and we just haven't bumped

55
00:02:43,400 --> 00:02:45,520
into each other because of the distance exactly.

56
00:02:46,080 --> 00:02:49,680
Speaker 2: We assume civilizations are static, or they stay in their lane.

57
00:02:49,719 --> 00:02:52,800
Hanson's team argues that this ignores the nature of life itself.

58
00:02:53,319 --> 00:02:56,879
Life expands to fill its container. If a civilization survives

59
00:02:56,879 --> 00:03:01,000
its adolescence, meaning it doesn't nuke itself and master space travel,

60
00:03:01,120 --> 00:03:03,159
it doesn't just sit there. It expands.

61
00:03:03,199 --> 00:03:05,439
Speaker 1: It needs resources, it needs everything.

62
00:03:06,039 --> 00:03:10,400
Speaker 2: The model defines a Grabby civilization by three criteria. They

63
00:03:10,439 --> 00:03:13,800
expand continuously, They expand effectively near the speed of light,

64
00:03:14,280 --> 00:03:16,639
and they make a visible impact on their environment.

65
00:03:16,840 --> 00:03:18,159
Speaker 1: So not just exploring.

66
00:03:18,319 --> 00:03:22,280
Speaker 2: They don't just explore. They restructure. They seize volume, matter

67
00:03:22,479 --> 00:03:27,240
and energy. They take apart stars, they re engineer galaxies.

68
00:03:26,879 --> 00:03:30,000
Speaker 1: So they are cosmic real estate developers on steroids.

69
00:03:30,439 --> 00:03:32,879
Speaker 2: Think of it like a phase transition. Imagine a pot

70
00:03:32,919 --> 00:03:35,960
of boiling water. You're these bubbles of steam forming at

71
00:03:36,000 --> 00:03:38,479
the bottom. What do the bubbles do? They get bigger,

72
00:03:38,560 --> 00:03:42,360
They don't stay small. They expand rapidly until they merge

73
00:03:42,360 --> 00:03:45,479
with other bubbles or break the surface. Hans in model

74
00:03:45,599 --> 00:03:48,479
civilizations as these expanding bubbles of control.

75
00:03:48,759 --> 00:03:51,560
Speaker 1: Okay, but this brings us back to the Fermi paradox immediately.

76
00:03:51,840 --> 00:03:53,599
If the universe is supposed to be full of these

77
00:03:53,639 --> 00:03:58,319
expanding bubbles rewriting galaxies and building dice in spheres, we

78
00:03:58,360 --> 00:04:00,560
would see them, you would think. So the night sky

79
00:04:00,599 --> 00:04:02,759
wouldn't be dark, it would be weird. We'd see patches

80
00:04:02,800 --> 00:04:05,520
of galaxies going dark as they get harvested, or maybe

81
00:04:05,639 --> 00:04:06,759
huge heat signatures.

82
00:04:07,039 --> 00:04:12,360
Speaker 2: Precisely, we see a pristine, natural universe, no waste heat signatures,

83
00:04:12,599 --> 00:04:16,879
no dismantled stars. And this is where the paper pulls

84
00:04:16,920 --> 00:04:20,600
a judo move on our intuition. Okay, most people say

85
00:04:20,959 --> 00:04:23,839
we see nothing, therefore we are alone. Hanson says, we

86
00:04:23,879 --> 00:04:25,360
see nothing, therefore we are early.

87
00:04:25,879 --> 00:04:29,439
Speaker 1: Early. How does that work? If the universe is thirteen

88
00:04:29,480 --> 00:04:32,800
point eight billion years old, how can we be early?

89
00:04:33,519 --> 00:04:36,199
Speaker 2: It comes down to selection bias. This is the part

90
00:04:36,240 --> 00:04:38,519
that's hard to wrap your head around. If we were

91
00:04:38,560 --> 00:04:41,480
living in a universe that was already full of grabby aliens,

92
00:04:41,519 --> 00:04:43,199
we wouldn't be here discussing.

93
00:04:42,800 --> 00:04:44,720
Speaker 1: It because we would have been paved over, right.

94
00:04:44,720 --> 00:04:47,360
Speaker 2: We would be part of their civilization. Yeah, Or more likely,

95
00:04:47,399 --> 00:04:49,360
we wouldn't exist at all because they would have harvested

96
00:04:49,360 --> 00:04:52,439
our solar system a billion years ago. The only time

97
00:04:52,480 --> 00:04:55,839
and place a pristine civilization like ours can't evolve is

98
00:04:55,839 --> 00:04:57,879
in the quiet gaps before the bubbles meet.

99
00:04:58,000 --> 00:04:59,759
Speaker 1: Okay, I see. So the fact that we look out

100
00:04:59,759 --> 00:05:02,160
in see an empty universe doesn't mean the universe is empty.

101
00:05:02,160 --> 00:05:04,959
It just means the front of their expansion hasn't hit

102
00:05:05,040 --> 00:05:07,240
our specific coordinates yet exactly.

103
00:05:07,279 --> 00:05:09,800
Speaker 2: We are existing in a pocket of silence, in the

104
00:05:10,079 --> 00:05:13,120
unpopped part of the popcorn bag, so to speak.

105
00:05:13,360 --> 00:05:15,399
Speaker 1: And the model actually predicts this.

106
00:05:15,680 --> 00:05:19,439
Speaker 2: Hanson's math actually predicts how big these bubbles should be

107
00:05:19,600 --> 00:05:22,000
and how fast they're moving. Based on the age of

108
00:05:22,040 --> 00:05:26,959
the universe. He calculates that these civilizations expanded a significant

109
00:05:27,000 --> 00:05:30,240
fraction of light speed, maybe roughly half the speed of light.

110
00:05:30,439 --> 00:05:33,040
Speaker 1: Half the speed of light. That is incredibly fast for

111
00:05:33,079 --> 00:05:33,839
a civilization.

112
00:05:34,120 --> 00:05:36,199
Speaker 2: It is I mean, we can't even get a probe

113
00:05:36,279 --> 00:05:38,800
to the next star in a human lifetime. They're crossing

114
00:05:38,800 --> 00:05:43,600
galactic voids, and it implies a hard deadline.

115
00:05:43,199 --> 00:05:44,040
Speaker 1: A deadline.

116
00:05:44,240 --> 00:05:46,319
Speaker 2: This is the nightmare part. We tend to think of

117
00:05:46,399 --> 00:05:49,439
space as this infinite frontier. We think we have trillions

118
00:05:49,480 --> 00:05:52,399
of years to explore the galaxy, star trek style.

119
00:05:52,160 --> 00:05:54,519
Speaker 1: Open ended go where no one has gone before.

120
00:05:54,720 --> 00:05:59,000
Speaker 2: The gravy aliens model says no, we are growing into

121
00:05:59,040 --> 00:06:02,000
a container. The walls of that container are rushing inward

122
00:06:02,079 --> 00:06:02,959
at half the speed of light.

123
00:06:03,040 --> 00:06:03,959
Speaker 1: That's claustrophobic.

124
00:06:04,040 --> 00:06:06,560
Speaker 2: It's the tsunami analogy, and this is really the core

125
00:06:06,600 --> 00:06:09,439
of the horror. Imagine you are standing on a beautiful beach.

126
00:06:10,000 --> 00:06:13,079
The water is calm, it looks perfect. You assume the

127
00:06:13,079 --> 00:06:16,120
ocean is safe. But what you don't know is that

128
00:06:16,160 --> 00:06:18,839
as tsunami is moving towards you at six hundred miles

129
00:06:18,839 --> 00:06:22,319
per hour, a wave one thousand feet high. You can't

130
00:06:22,319 --> 00:06:24,519
see it because of the curvature of the Earth.

131
00:06:24,439 --> 00:06:26,560
Speaker 1: Or in this case, the curvature of space time and

132
00:06:26,600 --> 00:06:28,120
the sheer distances.

133
00:06:27,800 --> 00:06:31,360
Speaker 2: Right the information the light from their expansion hasn't reached

134
00:06:31,399 --> 00:06:36,079
us yet, but the wave is real. It's existing right now,

135
00:06:36,519 --> 00:06:39,879
dismantling star systems, and it is rushing toward us.

136
00:06:40,199 --> 00:06:43,360
Speaker 1: So our pristine sky isn't a sign of peace. It's

137
00:06:43,399 --> 00:06:44,720
just a sign that we have a little bit of

138
00:06:44,759 --> 00:06:45,560
time left.

139
00:06:45,360 --> 00:06:49,680
Speaker 2: On the clock, and statistically not much time. In cosmic terms,

140
00:06:49,959 --> 00:06:52,720
the window for a civilization like ours to arise before

141
00:06:52,720 --> 00:06:56,839
the gratty ones fill the volume is narrow. Hanson argues,

142
00:06:56,879 --> 00:06:58,800
we are right at the tail end of the quiet

143
00:06:58,839 --> 00:07:00,360
era of the universe.

144
00:07:00,319 --> 00:07:02,439
Speaker 1: So we're basically squatting on a plot of land that's

145
00:07:02,439 --> 00:07:04,480
already been sold, waiting for the bulldozers.

146
00:07:04,560 --> 00:07:07,079
Speaker 2: Because the bulldozers move at near light speed, we won't

147
00:07:07,079 --> 00:07:09,639
see them coming, or rather we will see them exactly

148
00:07:09,680 --> 00:07:13,240
when they arrive. The sky will change. And then restructuring.

149
00:07:13,399 --> 00:07:15,600
Speaker 1: Restructuring, that's a polite way of saying extinction.

150
00:07:16,120 --> 00:07:19,160
Speaker 2: It's not necessarily malice. That's the thing that gets me.

151
00:07:19,199 --> 00:07:21,519
If you're building a highway, you don't hate the ant

152
00:07:21,560 --> 00:07:22,240
hill in your past.

153
00:07:22,319 --> 00:07:23,680
Speaker 1: Now you don't even think about it.

154
00:07:23,759 --> 00:07:26,040
Speaker 2: You don't declare war on the ants. You just pave

155
00:07:26,639 --> 00:07:30,560
to a grabby alien civilization. We are just buryonic matter.

156
00:07:30,759 --> 00:07:34,120
We are resources to be used for something more efficient.

157
00:07:34,279 --> 00:07:37,040
Speaker 1: That indifference is almost worse than a war, at least

158
00:07:37,079 --> 00:07:39,959
in a war you're recognized as an enemy. Here we're

159
00:07:40,000 --> 00:07:40,959
just gravel.

160
00:07:41,040 --> 00:07:45,839
Speaker 2: Correct. So that's nightmare number one. The external threat that

161
00:07:45,959 --> 00:07:50,199
is rushing toward us, unseen, hidden by the very laws

162
00:07:50,240 --> 00:07:52,000
of physics that limit our site.

163
00:07:52,160 --> 00:07:53,920
Speaker 1: Okay, I need to take a breath after that one.

164
00:07:53,959 --> 00:07:57,759
Let's pivot because if the tsunami is about something rushing

165
00:07:57,800 --> 00:08:00,959
at us, this next theory, where you suggest the threat

166
00:08:01,000 --> 00:08:03,600
is already here. It's just hitting the snooze button.

167
00:08:03,680 --> 00:08:05,600
Speaker 2: This is the estivation hypothesis.

168
00:08:05,639 --> 00:08:08,439
Speaker 1: Astivate. That's a biological term, right, like hibernation.

169
00:08:08,800 --> 00:08:11,720
Speaker 2: Yes, hibernation is what animals do to survive the winter.

170
00:08:12,160 --> 00:08:14,879
Aestivation is what animals do to survive the summer. It's

171
00:08:14,920 --> 00:08:18,399
avoiding the heat. This comes from a fascinating paper titled

172
00:08:18,519 --> 00:08:21,120
that is not dead, which can eternal lie? A great

173
00:08:21,120 --> 00:08:24,319
Lovecraft reference by Sandberg, Armstrong, and Cercovage.

174
00:08:24,360 --> 00:08:26,680
Speaker 1: I love a good academic paper with a horror title.

175
00:08:26,839 --> 00:08:30,639
So why would advanced aliens need to sleep through the summer?

176
00:08:30,720 --> 00:08:32,519
What is the summer? In this context?

177
00:08:32,720 --> 00:08:36,919
Speaker 2: The summer is right now, the current era of the universe.

178
00:08:37,399 --> 00:08:39,960
To understand this, you have to shift your thinking from

179
00:08:40,039 --> 00:08:44,960
biology to physics, specifically, Landauer's principle.

180
00:08:44,600 --> 00:08:47,039
Speaker 1: Walk us through that. I'm a bit rusty on my thermodynamics.

181
00:08:47,159 --> 00:08:51,120
Speaker 2: Landauer's principle links information to thermodynamics. It essentially says that

182
00:08:51,240 --> 00:08:55,559
processing information or raising a bit, making a calculation generates heat.

183
00:08:55,759 --> 00:08:58,679
There is a minimum energy cost to thinking, okay, and

184
00:08:58,720 --> 00:09:01,120
this cost is directly portional to temperature.

185
00:09:01,240 --> 00:09:03,600
Speaker 1: So the hotter the environment, the more expensive it is

186
00:09:03,639 --> 00:09:05,200
to thing exactly.

187
00:09:04,919 --> 00:09:07,879
Speaker 2: Much more expensive. If you are a biological creature like us,

188
00:09:07,960 --> 00:09:11,279
this doesn't matter much. Our brains are incredibly inefficient anyway.

189
00:09:11,679 --> 00:09:15,120
But most futurists and astrobiologists agree that biology is just.

190
00:09:15,120 --> 00:09:17,480
Speaker 1: A phase right the post biological future.

191
00:09:17,720 --> 00:09:23,919
Speaker 2: Eventually, intelligent civilizations upload their consciousness into machines. It's safer, faster,

192
00:09:24,080 --> 00:09:24,759
more durable.

193
00:09:24,960 --> 00:09:27,279
Speaker 1: We're already seeing the beginnings of that. With AI. We

194
00:09:27,360 --> 00:09:30,360
are moving toward a digital existence, right and if you.

195
00:09:30,320 --> 00:09:35,519
Speaker 2: Are a massive galaxy spanning digital civilization, your primary resource

196
00:09:36,080 --> 00:09:40,519
isn't oil or land, it is computation processing power.

197
00:09:40,639 --> 00:09:44,000
Speaker 1: And right now the universe is hot, exactly hot. Space

198
00:09:44,039 --> 00:09:46,440
seems pretty cold to me. It's like three degrees above

199
00:09:46,519 --> 00:09:47,440
absolute zero.

200
00:09:47,519 --> 00:09:49,720
Speaker 2: It's about three kelvin right now because of the cosmic

201
00:09:49,759 --> 00:09:53,639
microwave background radiation. To us, that's freezing. To a supercomputer

202
00:09:53,679 --> 00:09:56,399
trying to run a simulation of a trillion souls, that

203
00:09:56,559 --> 00:09:59,799
is a heat wave. It is thermal noise, it is inefficiency.

204
00:10:00,039 --> 00:10:02,120
It's like trying to run a server farm and a sauna.

205
00:10:02,279 --> 00:10:05,759
Speaker 1: So the smart move is to wait, just turn everything up.

206
00:10:05,840 --> 00:10:09,279
Speaker 2: The smart move is to estivate. The hypothesis suggests that

207
00:10:09,320 --> 00:10:12,519
advanced civilizations aren't dead. They've put themselves into a state

208
00:10:12,519 --> 00:10:15,559
of deep sleep. They've slowed their clocks, powered down their

209
00:10:15,600 --> 00:10:17,200
main systems, and they are waiting.

210
00:10:17,240 --> 00:10:18,120
Speaker 1: What are they waiting for.

211
00:10:18,360 --> 00:10:21,159
Speaker 2: They're waiting for the universe to expand and cool. They're

212
00:10:21,200 --> 00:10:23,480
waiting for the stars to burn out. They are waiting

213
00:10:23,519 --> 00:10:26,519
for the background radiation to fade toward absolute zero.

214
00:10:26,679 --> 00:10:27,600
Speaker 1: And when would that be.

215
00:10:28,519 --> 00:10:31,600
Speaker 2: Trillions of years from now, in the deep cold future

216
00:10:31,600 --> 00:10:34,639
of the universe, a single jewel of energy will be

217
00:10:34,639 --> 00:10:38,159
worth a quintillion times more in terms of computation than

218
00:10:38,200 --> 00:10:38,840
it is today.

219
00:10:39,240 --> 00:10:42,519
Speaker 1: That is an insane return on investment. It's like buying

220
00:10:42,559 --> 00:10:45,120
bitcoin in twenty ten versus buying it today, but on

221
00:10:45,159 --> 00:10:46,320
a cosmic scale.

222
00:10:46,360 --> 00:10:50,840
Speaker 2: It's simple economics. It's ultimate long term investing. To remain

223
00:10:50,960 --> 00:10:54,679
active now would be a grotesque waste of potential. It's

224
00:10:54,679 --> 00:10:56,399
like burning a pile of cash to heat your house

225
00:10:56,440 --> 00:10:58,399
in the middle of July. You just wouldn't do it.

226
00:10:58,399 --> 00:10:59,159
You'd wait for winter.

227
00:10:59,360 --> 00:11:01,919
Speaker 1: Okay, so they are sleeping. Why is that a nightmare

228
00:11:01,919 --> 00:11:03,919
for us? That sounds fine. We get the summer, they

229
00:11:03,919 --> 00:11:04,440
get the winter.

230
00:11:04,600 --> 00:11:07,679
Speaker 2: Win when because of us? Why haven't we heard from them?

231
00:11:07,840 --> 00:11:12,000
Because we are the noise. We are the energetic biological

232
00:11:12,120 --> 00:11:15,200
pests thriving in the heat wave. To them, we are

233
00:11:15,240 --> 00:11:17,159
short lived, inefficient, and loud.

234
00:11:17,320 --> 00:11:19,960
Speaker 1: We're the mosquitoes buzzing around the tent while they're trying

235
00:11:20,000 --> 00:11:20,399
to nap.

236
00:11:20,679 --> 00:11:23,720
Speaker 2: It's worse than that. Think about what we do. We

237
00:11:23,759 --> 00:11:28,679
dig up resources, we burn energy, we radiate heat. If

238
00:11:28,720 --> 00:11:34,440
we become a type two civilization, building Dyson spheres, harnessing

239
00:11:34,600 --> 00:11:35,279
entire stars.

240
00:11:35,360 --> 00:11:37,679
Speaker 1: It is our goal, right, the sci fi great, But.

241
00:11:37,679 --> 00:11:41,879
Speaker 2: In this scenario we are effectively stealing their future assets.

242
00:11:42,200 --> 00:11:44,159
Speaker 1: We are using up the stuff they're saving for the

243
00:11:44,159 --> 00:11:44,720
cold era.

244
00:11:45,039 --> 00:11:48,440
Speaker 2: Exactly, we are degrading their future resources. The analogy I

245
00:11:48,559 --> 00:11:51,600
use is termites. We are termites eating the foundation of

246
00:11:51,639 --> 00:11:54,679
the house while the owners are asleep upstairs, and we.

247
00:11:54,759 --> 00:11:56,480
Speaker 1: Think we own the house because we haven't seen the

248
00:11:56,480 --> 00:11:57,080
owners yet.

249
00:11:57,200 --> 00:11:59,720
Speaker 2: Right, We're running around making a mess, thinking this is all.

250
00:11:59,639 --> 00:12:02,279
Speaker 1: For us, and if the termites do enough damage.

251
00:12:01,960 --> 00:12:04,679
Speaker 2: The owners wake up and they won't be happy. The

252
00:12:04,799 --> 00:12:07,320
silence of the universe isn't empty, my friend, it's the

253
00:12:07,360 --> 00:12:10,519
silence of a library, and we're the only one shouting.

254
00:12:10,679 --> 00:12:14,480
Speaker 1: That gives me chills. That the idea that our success,

255
00:12:14,559 --> 00:12:17,799
our expansion, is actually a threat to something much older

256
00:12:17,799 --> 00:12:20,240
and more powerful. It means the better we do, the

257
00:12:20,240 --> 00:12:23,200
closer we get to being exterminated. As a pest control measure.

258
00:12:23,440 --> 00:12:26,279
Speaker 2: It flips the narrative of contact. We usually want to

259
00:12:26,320 --> 00:12:29,840
make contact. We send out voyager probes with maps to

260
00:12:29,919 --> 00:12:30,399
our house.

261
00:12:30,559 --> 00:12:32,759
Speaker 1: We're practically begging for it in this.

262
00:12:32,759 --> 00:12:36,440
Speaker 2: Scenario, making contact is the equivalent of a termite tapping

263
00:12:36,440 --> 00:12:39,799
on the floorboard loud enough to wake the giant. It's

264
00:12:39,919 --> 00:12:41,879
the dumbest thing we could possibly do.

265
00:12:42,279 --> 00:12:44,799
Speaker 1: So we have the tsunami rushing at us and the

266
00:12:44,840 --> 00:12:48,240
sleeping giants waiting to swat us. Let's move to scenario

267
00:12:48,360 --> 00:12:52,159
number three. This one feels a bit more aggressive active.

268
00:12:52,360 --> 00:12:54,679
Speaker 2: This is the Berserker probe scenario.

269
00:12:54,360 --> 00:12:58,360
Speaker 1: Berserker already the name suggests this isn't about economics. This

270
00:12:58,399 --> 00:12:59,279
is about violence.

271
00:12:59,399 --> 00:13:04,559
Speaker 2: You shouldn't lie. This transitions from strategic weighting to strategic hiding.

272
00:13:05,000 --> 00:13:07,879
It's based on the novels by Fred Zaberhagen, but it's

273
00:13:07,960 --> 00:13:11,440
rooted in a very real scientific concept, the self replicating

274
00:13:11,440 --> 00:13:13,559
spacecraft or the von Neumann probe.

275
00:13:13,639 --> 00:13:15,720
Speaker 1: Refresh our memory. On von Neumann prob.

276
00:13:15,600 --> 00:13:18,320
Speaker 2: John von Neuan, the mathematician, proposed that you could build

277
00:13:18,320 --> 00:13:21,799
a machine that goes to say an asteroid belt, minds

278
00:13:21,840 --> 00:13:23,960
raw materials, and then builds a copy of.

279
00:13:23,919 --> 00:13:25,799
Speaker 1: Itself, a self replicating machine.

280
00:13:25,960 --> 00:13:28,080
Speaker 2: Exactly. If you send one of those to a nearby

281
00:13:28,120 --> 00:13:31,279
star system, it builds two copies. Those two build four

282
00:13:31,600 --> 00:13:32,320
four Bild eight.

283
00:13:32,799 --> 00:13:35,879
Speaker 1: It's exponential growth, and because it's exponential, it fills the

284
00:13:35,879 --> 00:13:36,879
galaxy fast.

285
00:13:36,639 --> 00:13:40,200
Speaker 2: Incredibly fast. Even at slow sub light speeds, a single

286
00:13:40,240 --> 00:13:42,799
probe could colonize the entire Milky Way in just a

287
00:13:42,799 --> 00:13:45,879
few million years. That's a blink of an eye in

288
00:13:45,919 --> 00:13:46,679
cosmic time.

289
00:13:47,080 --> 00:13:48,960
Speaker 1: So the fact that we don't see them is a

290
00:13:48,960 --> 00:13:50,360
big deal, a huge deal.

291
00:13:50,480 --> 00:13:53,399
Speaker 2: The fact that we don't see these friendly probes, no hello,

292
00:13:53,440 --> 00:13:57,720
we come in piece robots, suggests that either no one

293
00:13:57,759 --> 00:14:02,279
builds them, or someone built a different kind, the the berserker.

294
00:14:02,759 --> 00:14:06,840
The hypothesis applies game theory, specifically the prisoner's dilemma to

295
00:14:06,919 --> 00:14:11,279
interstellar politics. It suggests the first civilization to achieve interstellar

296
00:14:11,320 --> 00:14:15,200
travel might have a horrific realization, which is competition is dangerous.

297
00:14:15,200 --> 00:14:18,279
If a neighbor can grow exponentially, they become a threat overnight.

298
00:14:18,399 --> 00:14:20,840
You can't trust them, you can't know their intentions, so

299
00:14:20,960 --> 00:14:24,840
you can't risk it. Exactly, so, to ensure your own survival,

300
00:14:25,120 --> 00:14:27,559
you need to ensure no one else can compete. You

301
00:14:27,600 --> 00:14:31,799
build kill vehicles, self replicating probes with a simple directive,

302
00:14:32,480 --> 00:14:36,480
detect intelligent life, extinguish it, reset.

303
00:14:36,039 --> 00:14:38,080
Speaker 1: And they just leave them out there like landmines.

304
00:14:38,919 --> 00:14:42,120
Speaker 2: Worse, they are hunters and they don't need to be

305
00:14:42,240 --> 00:14:46,039
massive death stars. That's inefficient. They can be small, stealthy,

306
00:14:46,200 --> 00:14:48,879
and dormant. The theory is that they might be lurking

307
00:14:48,879 --> 00:14:52,000
in the ort clouds of star systems, or drifting in

308
00:14:52,080 --> 00:14:55,360
the dark space between stars, just listening, listening for what

309
00:14:55,759 --> 00:15:00,799
radio waves, nuclear detonations, the chemical signatures of an industrial atmosphere,

310
00:15:00,879 --> 00:15:03,480
all the things we do, the things that screen technological

311
00:15:03,559 --> 00:15:06,679
civilization here yea, the things that announce to the cosmo

312
00:15:07,000 --> 00:15:09,759
that a new potential competitor has just reached the board.

313
00:15:09,840 --> 00:15:11,759
Speaker 1: Okay, so when they hear us, what happens?

314
00:15:11,840 --> 00:15:15,159
Speaker 2: The probe wakes up. It calculates the trajectory. It doesn't

315
00:15:15,159 --> 00:15:17,559
need a fancy laser or a warp drive. It just

316
00:15:17,600 --> 00:15:20,440
needs physics. It builds a kinetic impact essentially a large

317
00:15:20,519 --> 00:15:24,559
rock with an engine attached, and accelerates it to relativistic.

318
00:15:23,879 --> 00:15:27,639
Speaker 1: Speeds, a relativistic kill vehicle, a rock moving at ninety

319
00:15:27,679 --> 00:15:28,879
nine percent the speed of light.

320
00:15:29,240 --> 00:15:32,639
Speaker 2: Right, the energy released would be unmaginable. It would sterilize

321
00:15:32,679 --> 00:15:36,039
the entire planet. Or maybe it synthesizes a weaponized pathogen

322
00:15:36,159 --> 00:15:39,639
and drops it into our atmosphere. The point is it's cheap,

323
00:15:39,799 --> 00:15:41,879
it's automated, and it's effective, and.

324
00:15:41,840 --> 00:15:45,039
Speaker 1: It sends it our way. This explains the silence perfectly.

325
00:15:45,679 --> 00:15:48,200
The galaxy is quiet because everyone who makes a sound

326
00:15:48,240 --> 00:15:49,080
gets silenced.

327
00:15:49,200 --> 00:15:51,440
Speaker 2: It's the dark forest theory that six and Lou wrote

328
00:15:51,440 --> 00:15:55,799
about so brilliantly. The universe is a dark forest. Every

329
00:15:55,879 --> 00:15:59,679
civilization is an armed hunter stalking through the trees like

330
00:15:59,720 --> 00:16:03,279
a goo. If he finds another life, another hunter, an angel,

331
00:16:03,399 --> 00:16:05,679
or a demon, he can't determine if they are good

332
00:16:05,759 --> 00:16:08,240
or bad, but he knows they are a potential threat.

333
00:16:08,639 --> 00:16:10,639
So the only rational move is to shoot first.

334
00:16:10,679 --> 00:16:13,679
Speaker 1: And we Oh God, we have been broadcasting I Love

335
00:16:13,759 --> 00:16:17,080
Lucy and Hitler's speeches into space for one hundred years.

336
00:16:17,159 --> 00:16:20,399
Speaker 2: We have been screaming our location. We sent the voyager

337
00:16:20,440 --> 00:16:23,679
probes with maps to Earth, literal instructions on how to

338
00:16:23,720 --> 00:16:24,120
find us.

339
00:16:24,200 --> 00:16:27,200
Speaker 1: We have beamed high powered signals at star clusters to

340
00:16:27,200 --> 00:16:28,960
see if anyone answers if.

341
00:16:28,799 --> 00:16:32,639
Speaker 2: The berserker hypothesis is true. The message has already been received,

342
00:16:32,879 --> 00:16:35,919
the response program has been initiated, and the response it's

343
00:16:36,039 --> 00:16:38,799
likely already on its way, traveling at the speed of

344
00:16:38,879 --> 00:16:42,159
light or close to it, Silent and unstoppable.

345
00:16:42,360 --> 00:16:44,080
Speaker 1: We won't see it coming, not at.

346
00:16:44,000 --> 00:16:46,600
Speaker 2: All one day, the sky will just turn bright and

347
00:16:46,639 --> 00:16:48,440
then it will be over.

348
00:16:48,639 --> 00:16:52,559
Speaker 1: We are the noisy children walking through a dark forest, shouting,

349
00:16:52,759 --> 00:16:55,159
completely unaware of the wolves.

350
00:16:54,879 --> 00:16:58,639
Speaker 2: And the smart civilizations, the ones that survived, they not toe,

351
00:16:58,639 --> 00:17:01,240
stay quiet. That's why we don't hear them. They are

352
00:17:01,320 --> 00:17:03,320
hiding from the same thing that is coming for us.

353
00:17:03,360 --> 00:17:06,519
Speaker 1: That makes every radio telescope, every message we send out

354
00:17:06,559 --> 00:17:09,920
feel like a suicide note it does. It completely reframes

355
00:17:09,960 --> 00:17:14,359
our search for extraterrestrial intelligence SETI. We aren't explorers, We

356
00:17:14,400 --> 00:17:16,160
are toddlers playing with a loaded gun.

357
00:17:16,400 --> 00:17:19,480
Speaker 2: It brings a whole new meaning to searching for intelligence.

358
00:17:19,519 --> 00:17:21,400
We might be searching for our own executioner.

359
00:17:21,599 --> 00:17:24,799
Speaker 1: All right, that's terrifying. But notice a pattern here. Those

360
00:17:24,839 --> 00:17:30,319
first three grabby aliensesvation berserkers, they all involve other aliens

361
00:17:30,400 --> 00:17:31,160
destroying us.

362
00:17:31,279 --> 00:17:34,640
Speaker 2: True, they are xenophobic fears the threat is external.

363
00:17:34,880 --> 00:17:38,960
Speaker 1: But this fourth nightmare, this doesn't suggest maybe we don't

364
00:17:39,000 --> 00:17:41,559
need aliens to destroy us. Maybe we do a perfectly

365
00:17:41,559 --> 00:17:42,839
good job of that ourselves.

366
00:17:43,160 --> 00:17:47,319
Speaker 2: Correct. This is the great filter, and specifically the late

367
00:17:47,400 --> 00:17:49,160
filter or trapdoor scenario.

368
00:17:49,559 --> 00:17:51,720
Speaker 1: The great filter is pretty famous in these circles, but

369
00:17:51,880 --> 00:17:56,200
usually it's discussed someone abstractly, let's break down mechanics for

370
00:17:56,240 --> 00:17:56,839
the listeners.

371
00:17:57,119 --> 00:18:00,759
Speaker 2: The core logic is this, there must be some some

372
00:18:00,920 --> 00:18:05,279
statistical improbability that prevents dead matter from becoming a space

373
00:18:05,319 --> 00:18:09,680
faring civilization. Otherwise, given the age of the universe, the

374
00:18:09,720 --> 00:18:11,480
galaxy would be colonized by now.

375
00:18:11,599 --> 00:18:12,680
Speaker 1: Right, it should be full.

376
00:18:13,200 --> 00:18:15,920
Speaker 2: Since it looks empty, something is stopping the process.

377
00:18:16,079 --> 00:18:18,920
Speaker 1: And that's something is the filter. It filters out life.

378
00:18:19,039 --> 00:18:21,920
Speaker 2: Right now, there are two options option A. The filter

379
00:18:22,039 --> 00:18:25,400
is behind us. Maybe the origin of life is incredibly hard.

380
00:18:25,839 --> 00:18:28,319
Maybe going from single cells to multi cells is a

381
00:18:28,359 --> 00:18:29,559
one in a trillion shot.

382
00:18:29,680 --> 00:18:30,839
Speaker 1: That's the hopeful version.

383
00:18:31,039 --> 00:18:33,880
Speaker 2: If that's true, we are the lucky lottery winners. We

384
00:18:33,960 --> 00:18:36,880
made it. The hard part is over. The universes are

385
00:18:36,920 --> 00:18:38,119
oyster I like option A.

386
00:18:38,319 --> 00:18:40,680
Speaker 1: Option A makes as special, It makes us the chosen ones.

387
00:18:40,920 --> 00:18:43,759
Speaker 2: We all like option A. But the science is starting

388
00:18:43,759 --> 00:18:46,079
to point away from it. We are finding the building

389
00:18:46,119 --> 00:18:50,279
blocks of life everywhere. Water on Mars, phosphene on Venus,

390
00:18:50,559 --> 00:18:54,039
amino acids on comets. Life seems easy, or at.

391
00:18:54,039 --> 00:18:56,160
Speaker 1: Least the ingredients are common, very common.

392
00:18:56,440 --> 00:19:00,079
Speaker 2: Yeah, in intelligence seems to be a huge evolutionary advantage.

393
00:19:00,200 --> 00:19:04,039
So If life is easy and intelligence.

394
00:19:03,440 --> 00:19:05,960
Speaker 1: Is natural, then the filter isn't behind us, it's.

395
00:19:05,839 --> 00:19:08,480
Speaker 2: Ahead of us. This is the horror of the late filter.

396
00:19:09,039 --> 00:19:12,359
It' suggests that civilizations arise constantly. They build cities, they

397
00:19:12,400 --> 00:19:15,480
discover the atom, they invent radio, they launch rockets, and then,

398
00:19:15,599 --> 00:19:19,039
without exception, they die. They hit a wall, a trapdoor.

399
00:19:19,480 --> 00:19:21,480
The silence of the universe isn't because no one is

400
00:19:21,480 --> 00:19:23,440
playing the game. It's because the game is rigged to

401
00:19:23,480 --> 00:19:26,000
kill the player at level ten, and we're at level

402
00:19:26,079 --> 00:19:27,079
nine about to level up.

403
00:19:27,160 --> 00:19:29,559
Speaker 1: What is the trap? Is it war? Climate change?

404
00:19:29,599 --> 00:19:32,359
Speaker 2: Those are probably minor filters. They might kill some civilizations,

405
00:19:32,359 --> 00:19:34,480
but all of them every single time. The great filter

406
00:19:34,519 --> 00:19:35,960
has to be something more universal.

407
00:19:36,119 --> 00:19:36,480
Speaker 1: Okay.

408
00:19:37,000 --> 00:19:40,279
Speaker 2: Oxford philosopher Nick Bostrom warns about this. He calls it

409
00:19:40,319 --> 00:19:43,799
a technology that is too easy to invent but too

410
00:19:43,839 --> 00:19:49,160
destructive to control. The easy nuke exactly. Think about nuclear weapons.

411
00:19:49,200 --> 00:19:51,599
They are terrifying, but they are hard to build. You

412
00:19:51,680 --> 00:19:56,359
need state level infrastructure, centrifuges, rare isotopes. It limits who

413
00:19:56,359 --> 00:19:56,880
can use them.

414
00:19:56,960 --> 00:19:58,920
Speaker 1: It keeps them in the hands of a few, which

415
00:19:59,000 --> 00:19:59,880
is scary enough.

416
00:20:00,000 --> 00:20:04,000
Speaker 2: But imagine if destroying a city didn't require uranium. Imagine

417
00:20:04,000 --> 00:20:05,880
if you could do it with a microwave oven and

418
00:20:05,960 --> 00:20:07,880
some chemicals you could buy at a hardware store.

419
00:20:07,960 --> 00:20:10,519
Speaker 1: If that were true, civilization would end in a week.

420
00:20:10,839 --> 00:20:14,480
All it takes is one nihilist, one crazy person, one mistake.

421
00:20:14,759 --> 00:20:18,559
Speaker 2: Precisely, if such a technology exists, something that allows a

422
00:20:18,559 --> 00:20:22,240
single individual to destroy a planet, and if that technology

423
00:20:22,279 --> 00:20:26,200
lies on the inevitable path of scientific progress, then statistical

424
00:20:26,319 --> 00:20:29,160
ruin is guaranteed. It's not a matter of if, but when.

425
00:20:29,319 --> 00:20:32,799
Speaker 1: And we are advancing fast. We are democratizing technology, AI,

426
00:20:33,000 --> 00:20:37,039
synthetic biology, nanotechnology. We are putting godlike powers into the

427
00:20:37,039 --> 00:20:38,799
hands of smaller and smaller groups.

428
00:20:39,000 --> 00:20:41,720
Speaker 2: That's the funeral march. If the late filter is real,

429
00:20:41,839 --> 00:20:44,519
then every breakthrough we make is in progress. It's a

430
00:20:44,559 --> 00:20:45,640
step toward the trip wire.

431
00:20:46,039 --> 00:20:48,200
Speaker 1: So finding life on Mars would be the worst news

432
00:20:48,200 --> 00:20:49,440
in human history.

433
00:20:49,279 --> 00:20:52,440
Speaker 2: The absolute worst. Finding fossils on Mars would mean that

434
00:20:52,559 --> 00:20:55,519
life isn't the filter. That means the filter is almost

435
00:20:55,559 --> 00:20:59,039
certainly ahead of us. The emptier the universe seems, the

436
00:20:59,119 --> 00:21:00,000
better our chances.

437
00:21:00,400 --> 00:21:02,720
Speaker 1: We look at the stars and wonder where everyone is.

438
00:21:03,279 --> 00:21:06,240
The answer might be that we are standing in a graveyard.

439
00:21:06,359 --> 00:21:08,599
But we haven't dug our own plot yet.

440
00:21:08,799 --> 00:21:11,920
Speaker 2: The quiet isn't peace. The quiet is the aftermath.

441
00:21:12,000 --> 00:21:16,880
Speaker 1: Civilizations pop up, get loud, discover the easy nuke. Maybe

442
00:21:16,880 --> 00:21:19,880
it's a bioengineered virus, maybe it's gray goo, and then

443
00:21:19,920 --> 00:21:22,599
go silent, over and over again. We are just the

444
00:21:22,640 --> 00:21:24,440
next ones in line to find out what it.

445
00:21:24,400 --> 00:21:27,079
Speaker 2: Is, and we're running towards it thinking it's progress.

446
00:21:27,200 --> 00:21:29,599
Speaker 1: That's heavy. It makes you look at a headline about

447
00:21:29,640 --> 00:21:32,160
a new scientific discovery and think, is this the one?

448
00:21:32,240 --> 00:21:33,359
Is this the one that kills us?

449
00:21:33,480 --> 00:21:37,319
Speaker 2: It promotes a very different view of progress. Progress becomes dangerous.

450
00:21:37,960 --> 00:21:40,359
It suggests that knowledge itself might be the weapon.

451
00:21:40,480 --> 00:21:44,119
Speaker 1: Okay, we've covered external threats, internal threats. Now let's get weird.

452
00:21:44,240 --> 00:21:44,880
Speaker 2: Let's get weird.

453
00:21:45,319 --> 00:21:48,960
Speaker 1: Nightmare number five. This one unsettles me because it's about

454
00:21:48,960 --> 00:21:51,839
things we can't see but are right here, literally in

455
00:21:51,880 --> 00:21:54,279
this room, the shadow biosphere.

456
00:21:54,480 --> 00:21:58,880
Speaker 2: This moves us from distant threats to uncomfortable intimacy. This

457
00:21:58,920 --> 00:22:01,799
is based on proposals by scientists Carol Cleland and others.

458
00:22:02,359 --> 00:22:05,720
It starts with a simple question. When we look for life,

459
00:22:06,160 --> 00:22:07,000
what do we look for?

460
00:22:07,240 --> 00:22:11,000
Speaker 1: We look for stuff like us, carbon, water, DNA, exactly.

461
00:22:11,240 --> 00:22:15,240
Speaker 2: We scan the Goldilocks zones. We analyze for biosignature that

462
00:22:15,319 --> 00:22:18,480
our kind of life produces, but that assumes all life

463
00:22:18,519 --> 00:22:22,279
follows a specific chemical pathway that happened on Earth. Cleveland

464
00:22:22,319 --> 00:22:25,279
suggests there could be a shadow biosphere right here on.

465
00:22:25,160 --> 00:22:27,119
Speaker 1: Earth, like a second tree of life.

466
00:22:27,279 --> 00:22:30,200
Speaker 2: Yes, life may have emerged on Earth more than once

467
00:22:30,440 --> 00:22:34,200
with a completely different biochemical foundation. We are the descendants

468
00:22:34,279 --> 00:22:36,920
of the standard origin event, but there could be a

469
00:22:37,000 --> 00:22:40,079
chemically distinct biosphere existing right alongside us.

470
00:22:40,079 --> 00:22:41,079
Speaker 1: Oh, what that even look like?

471
00:22:41,279 --> 00:22:45,519
Speaker 2: Microbes that don't have DNA, organisms that process artsynic instead

472
00:22:45,519 --> 00:22:49,359
of phosphorus, or use different chirality in their molecules. Mirror

473
00:22:49,400 --> 00:22:50,400
images are the ones.

474
00:22:50,240 --> 00:22:51,640
Speaker 1: We use, and we don't see them.

475
00:22:51,839 --> 00:22:54,079
Speaker 2: We don't see them because our tools are built to

476
00:22:54,119 --> 00:22:57,359
find us. We use PCR tests that look for DNA.

477
00:22:58,000 --> 00:23:01,079
If something doesn't have DNA, it's invisible to us. We

478
00:23:01,160 --> 00:23:03,839
might be scrubbing shadow life off our kitchen counters and

479
00:23:03,839 --> 00:23:06,359
not even knowing it. It's the ultimate blind spot.

480
00:23:06,400 --> 00:23:09,240
Speaker 1: Okay, that's creepy, but how does it explain the silence

481
00:23:09,279 --> 00:23:10,000
of the universe.

482
00:23:10,119 --> 00:23:13,400
Speaker 2: Expand that concept to the cosmos. Look at the composition

483
00:23:13,480 --> 00:23:17,319
of the universe. Normal matter, the stuff stars, planets, and

484
00:23:17,400 --> 00:23:18,160
you and I are made of.

485
00:23:18,359 --> 00:23:19,680
Speaker 1: Marionic matter, is.

486
00:23:19,599 --> 00:23:21,680
Speaker 2: Only up fifteen percent of the matter in the universe.

487
00:23:21,960 --> 00:23:24,039
Some sources say as little as five percent of the

488
00:23:24,039 --> 00:23:27,920
total mass energy, and the rest dark matter about eighty

489
00:23:27,920 --> 00:23:30,839
five percent of the matter. It's the gravitational scaffolding that

490
00:23:30,880 --> 00:23:32,039
holds galaxies together.

491
00:23:32,440 --> 00:23:35,160
Speaker 1: So we are the minority. We are the afterthought.

492
00:23:35,400 --> 00:23:37,480
Speaker 2: We are the cosmic scum on top of the pond.

493
00:23:37,680 --> 00:23:42,160
The anomaly. The shadow biosphere theory asks, if physics allows

494
00:23:42,160 --> 00:23:45,039
for complex structures in normal matter, why not in the

495
00:23:45,119 --> 00:23:47,119
dark sector, why not dark life?

496
00:23:47,319 --> 00:23:49,680
Speaker 1: So the universe could be teeming with life, but it's

497
00:23:49,720 --> 00:23:50,759
all made of dark.

498
00:23:50,599 --> 00:23:53,400
Speaker 2: Matter, densely populated, just not with diaryonic beat. That's us.

499
00:23:53,440 --> 00:23:55,319
The universe isn't empty. We're just looking in the wrong

500
00:23:55,359 --> 00:23:56,279
place with the wrong eyes.

501
00:23:56,599 --> 00:23:59,640
Speaker 1: The horror here is the intangibility completely.

502
00:24:00,119 --> 00:24:02,799
Speaker 2: There could be a civilization existing in this room right now.

503
00:24:03,759 --> 00:24:07,920
Complex intelligent structures made of dark matter passing through your body,

504
00:24:07,960 --> 00:24:09,200
through the Earth, through the Sun.

505
00:24:09,079 --> 00:24:10,480
Speaker 1: And they don't interact with us.

506
00:24:10,720 --> 00:24:13,839
Speaker 2: Dark matter only interacts vio gravity, if at all. On

507
00:24:13,880 --> 00:24:15,960
local scales, they would pass right through us. Like we

508
00:24:16,000 --> 00:24:18,359
aren't even there, so we are ghosts to them. Or

509
00:24:18,359 --> 00:24:20,319
there it goes to us, we are the blind men

510
00:24:20,359 --> 00:24:23,039
in a crowded room. We assume we are alone because

511
00:24:23,039 --> 00:24:26,480
we cannot see. But statistically it is arrogant to assume

512
00:24:26,480 --> 00:24:29,799
that only the fifteen percent of visible matter can support complexity.

513
00:24:29,880 --> 00:24:32,200
The universe could be dominated by dark life.

514
00:24:32,559 --> 00:24:34,960
Speaker 1: The idea that I could be walking through an alien

515
00:24:35,119 --> 00:24:38,079
city right now and not know it. It makes you

516
00:24:38,160 --> 00:24:39,680
feel incredibly vulnerable.

517
00:24:39,920 --> 00:24:43,359
Speaker 2: And here is the darker implication. What if they are

518
00:24:43,400 --> 00:24:46,319
aware of us. We can't interact with them, but maybe

519
00:24:46,319 --> 00:24:49,000
they can interact with us. What if we aren't ghosts?

520
00:24:49,640 --> 00:24:51,119
What if we are live stock?

521
00:24:51,359 --> 00:24:53,160
Speaker 1: Whoa live stock?

522
00:24:53,480 --> 00:24:56,319
Speaker 2: If the shadow biosphere exists, and if it is more

523
00:24:56,359 --> 00:24:59,359
advanced or more populous than us, we have no way

524
00:24:59,440 --> 00:25:03,160
of knowing that intent or their capabilities. We are vulnerable

525
00:25:03,160 --> 00:25:06,160
to force as we literally cannot touch. We might be

526
00:25:06,200 --> 00:25:09,240
an energy source, we might be an experiment. We might

527
00:25:09,279 --> 00:25:12,079
be something they just tolerate, like mold in the corners

528
00:25:12,079 --> 00:25:13,759
of their vast invisible house.

529
00:25:14,079 --> 00:25:16,839
Speaker 1: That is a special kind of paranoia. The idea that

530
00:25:17,039 --> 00:25:20,119
the empty room is actually full and everyone is just

531
00:25:20,279 --> 00:25:21,359
watching you, and you.

532
00:25:21,319 --> 00:25:25,039
Speaker 2: Can't watch back. You are physically incapable of looking back.

533
00:25:25,079 --> 00:25:27,400
You don't even have the senses to know you're being watched.

534
00:25:27,839 --> 00:25:30,839
Speaker 1: All right, we've arrived at the final nightmare number six.

535
00:25:31,160 --> 00:25:35,000
And this one, this one isn't about biological death. It's

536
00:25:35,039 --> 00:25:36,960
about the end of reality.

537
00:25:36,440 --> 00:25:38,160
Speaker 2: Itself, the simulation termination.

538
00:25:38,440 --> 00:25:40,079
Speaker 1: This is the one that makes you question if the

539
00:25:40,160 --> 00:25:41,519
chair you're sitting on is real.

540
00:25:41,839 --> 00:25:45,880
Speaker 2: This comes from the simulation argument famously popularized by Nick Bostrom.

541
00:25:46,440 --> 00:25:48,960
He's really the king of existential dread, isn't he?

542
00:25:48,960 --> 00:25:51,440
Speaker 1: He really is? But this goes beyond the matrix. This

543
00:25:51,519 --> 00:25:52,559
isn't about breaking.

544
00:25:52,359 --> 00:25:55,599
Speaker 2: Out, No, this is about the statistics of existence. The

545
00:25:55,720 --> 00:26:01,359
argument relies on three statistical premises. Oneizations capable of running

546
00:26:01,400 --> 00:26:06,680
ancestor simulations. Hyperrealistic simulations of their past are possible.

547
00:26:06,279 --> 00:26:10,440
Speaker 1: Which seems plausible given our trajectory with VR and AI plausible.

548
00:26:11,119 --> 00:26:14,960
Speaker 2: Two such similations would run, many, many of them, billions

549
00:26:15,319 --> 00:26:20,680
to study history, sociology to run experiments. And premise three, Therefore,

550
00:26:20,920 --> 00:26:26,240
there are billions of simulated minds for everyone real biological mind.

551
00:26:26,359 --> 00:26:29,799
So statistically, statistically, if you are a conscious being, it

552
00:26:29,880 --> 00:26:33,319
is overwhelmingly likely ninety nine point ninety nine nine nine

553
00:26:33,359 --> 00:26:35,759
percent likely that you are in a simulation. You are

554
00:26:35,759 --> 00:26:36,920
not in base reality.

555
00:26:37,000 --> 00:26:39,480
Speaker 1: Okay, I've heard this before, but why is this a nightmare?

556
00:26:39,480 --> 00:26:40,960
Why does this explain the silence?

557
00:26:42,160 --> 00:26:44,160
Speaker 2: It becomes a horror scenario when you look at the

558
00:26:44,200 --> 00:26:47,559
termination condition. The simulation is run for a purpose, But

559
00:26:47,640 --> 00:26:50,839
simulations have limits. They have limited ram, limited processing power.

560
00:26:50,920 --> 00:26:52,640
Speaker 1: Even the supercomputers of the future have.

561
00:26:52,640 --> 00:26:56,400
Speaker 2: Limits exactly, and we the simulated beings, are consuming resources

562
00:26:56,680 --> 00:26:59,519
as humanity expands, as we build around supercomputers, as we

563
00:26:59,680 --> 00:27:01,359
try to simulate our own universes.

564
00:27:01,400 --> 00:27:03,799
Speaker 1: Within this one, we're nesting simulations.

565
00:27:03,920 --> 00:27:07,319
Speaker 2: The computational load on the host machine increases exponentially.

566
00:27:07,400 --> 00:27:08,640
Speaker 1: We are lagging the server.

567
00:27:09,039 --> 00:27:11,960
Speaker 2: We are entering the danger zone, and there is evidence.

568
00:27:12,039 --> 00:27:16,279
Look at quantum mechanics the observer effect. Things only exist

569
00:27:16,319 --> 00:27:18,319
in a definite state when you look at them.

570
00:27:18,440 --> 00:27:20,519
Speaker 1: That sounds suspiciously like a video game.

571
00:27:20,640 --> 00:27:23,960
Speaker 2: It looks exactly like optimization algorithms in a game engine,

572
00:27:24,079 --> 00:27:26,519
rendering only what is being looked at to save memory.

573
00:27:26,839 --> 00:27:29,440
Plank lengths look like pixels, the speed of light looks

574
00:27:29,480 --> 00:27:32,039
like a processor speed limit, the maximum rate at which

575
00:27:32,119 --> 00:27:34,119
information can move across the grid.

576
00:27:34,000 --> 00:27:37,160
Speaker 1: So the universe looks empty because because the developers didn't

577
00:27:37,160 --> 00:27:40,839
bother to code the rest of the NPCs, non player characters.

578
00:27:41,000 --> 00:27:44,599
Speaker 2: Why render billions of alien civilizations if the simulation is

579
00:27:44,640 --> 00:27:48,599
only about Earth. If the experiment is how does humanity

580
00:27:48,720 --> 00:27:51,920
handle the twenty first century? Oh, you don't need aliens,

581
00:27:52,319 --> 00:27:55,240
You just need a skybox, a background render of stars

582
00:27:55,240 --> 00:27:56,119
that aren't really there.

583
00:27:56,200 --> 00:27:59,920
Speaker 1: It's just a painted ceiling, a beautiful high resolution jape.

584
00:28:00,599 --> 00:28:04,839
Speaker 2: And here is the terrifying implication. If the simulation is

585
00:28:04,839 --> 00:28:08,279
an experiment, say to answer the question, how does a

586
00:28:08,319 --> 00:28:12,519
civilization evolve from nuclear power to AI? What happens when

587
00:28:12,559 --> 00:28:13,359
we answer the question?

588
00:28:13,440 --> 00:28:17,640
Speaker 1: When we get there, when we achieve superintelligence or crack fusion.

589
00:28:17,759 --> 00:28:20,960
Speaker 2: When the data is gathered, the simulation is no longer useful.

590
00:28:21,200 --> 00:28:23,880
It is just a drain on power. The moment we

591
00:28:23,920 --> 00:28:26,640
truly understand the theory of everything, the moment we crack

592
00:28:26,720 --> 00:28:27,319
the code of the.

593
00:28:27,319 --> 00:28:29,640
Speaker 1: Universe, the experiment concludes.

594
00:28:29,200 --> 00:28:33,079
Speaker 2: The screen goes black. Yeah, no apocalypse, no fire and Brimstone,

595
00:28:33,480 --> 00:28:37,000
just end of program. We are racing toward a finish

596
00:28:37,039 --> 00:28:39,440
line that is actually a cliff, and we're running faster

597
00:28:39,519 --> 00:28:40,119
every day.

598
00:28:40,039 --> 00:28:43,279
Speaker 1: So our curiosity, our drive to understand the universe, is

599
00:28:43,319 --> 00:28:45,240
actually rushing us toward the off switch.

600
00:28:45,599 --> 00:28:48,400
Speaker 2: We are trying to solve the puzzle, not realizing that

601
00:28:48,519 --> 00:28:52,359
solving the puzzle ends the game. It reframes scientific discovery

602
00:28:52,400 --> 00:28:55,480
as a countdown clock. Every new paper in physics is

603
00:28:55,519 --> 00:28:56,839
one tick closer to zero.

604
00:28:56,960 --> 00:29:00,440
Speaker 1: Wow. Okay, let's take a breath, deep breath. We have

605
00:29:00,519 --> 00:29:04,000
been through the ringer today. We've talked about grabby aliens

606
00:29:04,079 --> 00:29:07,000
rushing at us like a tsunami. We've talked about sleeping

607
00:29:07,000 --> 00:29:10,119
giants who see us as termites. We've talked about berserker

608
00:29:10,240 --> 00:29:11,720
probes hunting us in the dark.

609
00:29:11,839 --> 00:29:15,920
Speaker 2: We discussed the great filter, the trapdoor that kills every civilization,

610
00:29:16,400 --> 00:29:20,240
the shadow biosphere, the ghosts walking through us, and finally

611
00:29:20,720 --> 00:29:24,079
the simulation termination, the plug pull.

612
00:29:24,480 --> 00:29:26,880
Speaker 1: It's a lot, and it completely changes how you look

613
00:29:26,920 --> 00:29:30,000
at that night sky. That feeling of peace is gone.

614
00:29:30,079 --> 00:29:34,000
Speaker 2: It is the silence isn't empty, It is heavy with information.

615
00:29:34,279 --> 00:29:36,440
It's screaming at us if we know how to listen.

616
00:29:36,599 --> 00:29:38,440
Speaker 1: I want to leave the listeners with a final thought.

617
00:29:38,640 --> 00:29:40,839
We started with the beauty of the stars, but now

618
00:29:40,920 --> 00:29:43,599
I have to ask is it better to be alone?

619
00:29:44,279 --> 00:29:46,160
Is it better to be the only life in a

620
00:29:46,279 --> 00:29:49,039
vast empty universe? Or is it better to be in

621
00:29:49,079 --> 00:29:51,839
a crowded room where everyone is holding their breath hiding

622
00:29:51,880 --> 00:29:52,519
from something.

623
00:29:52,880 --> 00:29:55,960
Speaker 2: That is the question, solitude or suspense. I think I

624
00:29:56,039 --> 00:29:58,680
prefer the solitude, even if it's lonely. The alternative is

625
00:29:59,519 --> 00:30:00,960
hunt or be hunted.

626
00:30:01,160 --> 00:30:03,759
Speaker 1: I don't know. Being the only consciousness in the universe

627
00:30:03,799 --> 00:30:06,079
feels like a lot of pressure, But being a termite

628
00:30:06,119 --> 00:30:08,039
in a sleeping giant's house isn't.

629
00:30:07,839 --> 00:30:11,599
Speaker 2: Great either, and being a line of code is just depressing.

630
00:30:11,480 --> 00:30:14,720
Speaker 1: Truly, So we want to know where you stand. Which

631
00:30:14,720 --> 00:30:17,200
of these scenarios keeps you up at night? Are we

632
00:30:17,240 --> 00:30:20,279
the termites, annoying the sleepers? Are we walking into a

633
00:30:20,319 --> 00:30:23,319
trip wire? Or are we just expensive software waiting for

634
00:30:23,359 --> 00:30:24,079
the delete key.

635
00:30:24,519 --> 00:30:27,640
Speaker 2: I'm bidding on the berserkers personally. It explains of radio

636
00:30:27,680 --> 00:30:31,920
silence too well. The game theory is just it's brutal,

637
00:30:32,079 --> 00:30:34,880
but it's sound. The math just works.

638
00:30:35,160 --> 00:30:39,359
Speaker 1: I'm going with simulation. It feels the most plausible given

639
00:30:39,440 --> 00:30:42,599
our own trajectory with AI and computing. It just fits

640
00:30:42,640 --> 00:30:45,519
too well with the weirdness of quantum physics.

641
00:30:45,680 --> 00:30:48,559
Speaker 2: Fair enough. Either way, we're in trouble.

642
00:30:48,319 --> 00:30:49,839
Speaker 1: Leave a comment and tell us what you think. We

643
00:30:49,880 --> 00:30:52,559
want to hear your theories, your fears, and maybe your hopes.

644
00:30:52,640 --> 00:30:53,319
If you have any.

645
00:30:53,240 --> 00:30:54,759
Speaker 2: Left after this, we could use them.

646
00:30:54,799 --> 00:30:57,640
Speaker 1: Op. We really could. Until next time, keep looking up,

647
00:30:57,839 --> 00:31:00,000
even if it scares you. This has been thrilling thereat.

648
00:31:00,400 --> 00:31:01,359
Speaker 2: Stay safe out there,
