1
00:00:00,120 --> 00:00:03,759
Speaker 1: Greeting's curious minds, and welcome to the deep dive. Today,

2
00:00:04,000 --> 00:00:07,559
we're plunging into a story that's well, it's so chilling,

3
00:00:07,639 --> 00:00:08,519
so audacious, it.

4
00:00:08,439 --> 00:00:10,519
Speaker 2: Honestly sounds like science fiction, right, like something out of

5
00:00:10,519 --> 00:00:11,679
a dystopian.

6
00:00:11,199 --> 00:00:16,120
Speaker 1: Novel exactly, except it's profoundly real, happened in our history,

7
00:00:16,199 --> 00:00:19,399
and a lot of it is still shrouded in secrecy.

8
00:00:19,879 --> 00:00:23,199
Imagine just for a second, a single weapon so utterly

9
00:00:23,280 --> 00:00:27,239
powerful it was conceived with well one purpose, wipe out

10
00:00:27,320 --> 00:00:28,480
all of human civilization.

11
00:00:28,800 --> 00:00:31,519
Speaker 2: A bomb not really designed to win a war, but

12
00:00:31,719 --> 00:00:36,000
just to end existence itself, like a full stop on humanity.

13
00:00:36,079 --> 00:00:37,240
Speaker 1: Yeah, a final period.

14
00:00:37,520 --> 00:00:40,200
Speaker 2: And what's truly fascinating here isn't just the scale, which

15
00:00:40,200 --> 00:00:44,399
is almost incomprehensible. Really, it's the cold, calculating logic behind it,

16
00:00:44,520 --> 00:00:47,479
and the sheer terror that led some really brilliant minds

17
00:00:47,479 --> 00:00:48,520
back then even think about it.

18
00:00:48,560 --> 00:00:50,719
Speaker 1: We're talking about a top secret project from the nineteen

19
00:00:50,799 --> 00:00:52,840
fifties code named Sun Dial.

20
00:00:52,960 --> 00:00:56,079
Speaker 2: And its goal. Its literal goal was to build the

21
00:00:56,200 --> 00:00:58,560
ultimate doomsday device, nothing less, and.

22
00:00:58,520 --> 00:01:00,640
Speaker 1: When we say ultimate, we really mean it. Project sun

23
00:01:00,679 --> 00:01:04,319
Dial was theorized to pack the energy of at least

24
00:01:04,359 --> 00:01:06,359
ten billion tons of TNT.

25
00:01:06,319 --> 00:01:08,840
Speaker 2: Ten billion tons. It's hard to even.

26
00:01:08,680 --> 00:01:12,159
Speaker 1: Visualize, right, To try and put that in perspective, imagine

27
00:01:12,159 --> 00:01:15,640
a pyramid made of explosives. It would be thirteen times

28
00:01:15,719 --> 00:01:17,680
taller than the Great Pyramid of Giza.

29
00:01:17,959 --> 00:01:18,200
Speaker 2: Wow.

30
00:01:18,439 --> 00:01:21,840
Speaker 1: Or get this, three thousand times more powerful than all

31
00:01:21,840 --> 00:01:23,840
the bombs dropped in World War Two combined.

32
00:01:23,959 --> 00:01:25,400
Speaker 2: Three thousand times. Yes.

33
00:01:25,599 --> 00:01:29,840
Speaker 1: And if you drop the herosomal bomb every single minute, NonStop,

34
00:01:30,280 --> 00:01:33,239
it would take you over fifteen months to match the

35
00:01:33,280 --> 00:01:36,079
power of just one sun dial detonation.

36
00:01:36,200 --> 00:01:39,239
Speaker 2: It's a number so huge it almost loses meaning. Doesn't

37
00:01:39,280 --> 00:01:42,280
it just beyond our scale completely? And this wasn't just

38
00:01:42,319 --> 00:01:45,000
you know, some theoretical scribble on a napkin. This was

39
00:01:45,040 --> 00:01:48,640
a serious project. Yeah, conceived by a genius physicist. There

40
00:01:48,680 --> 00:01:53,480
were actual design plans discussed, engineering challenges tackled, even a

41
00:01:53,719 --> 00:01:55,239
preliminary tests talked about.

42
00:01:55,359 --> 00:01:57,640
Speaker 1: So our mission today is to really dive deep into

43
00:01:57,680 --> 00:02:00,359
the story of Projects Sundial. We want to unpack world

44
00:02:00,359 --> 00:02:03,519
that could even dream up such a terrifying idea, explore

45
00:02:03,599 --> 00:02:07,079
the brilliant and maybe terrifyingly driven mind behind it.

46
00:02:07,319 --> 00:02:09,960
Speaker 2: And ultimately sort of confront what its legacy means for

47
00:02:10,080 --> 00:02:12,280
us today, right, because we still live in the shattery

48
00:02:12,319 --> 00:02:14,879
of that kind of power, even if it's distributed differently.

49
00:02:14,919 --> 00:02:18,960
Speaker 1: Now, so what can this almost forgotten piece of history

50
00:02:19,080 --> 00:02:22,560
teach us. Let's dive in. Let's confront the nightmare we

51
00:02:22,680 --> 00:02:24,680
almost almost unleashed.

52
00:02:24,319 --> 00:02:27,000
Speaker 2: And maybe reflect on that thin line between deterring your

53
00:02:27,080 --> 00:02:29,479
enemies and just ultimate annihilation.

54
00:02:29,599 --> 00:02:31,560
Speaker 1: Okay, so let's unpack this to really get our heads

55
00:02:31,560 --> 00:02:36,000
around the mindset, the sheer audacity really that could conceive

56
00:02:36,039 --> 00:02:39,080
of sun dial We need to rewind. Try to imagine

57
00:02:39,120 --> 00:02:41,840
being say forty years old in nineteen forty five.

58
00:02:41,800 --> 00:02:44,800
Speaker 2: Right, which means you were born around nineteen oh five exactly.

59
00:02:44,840 --> 00:02:48,520
Speaker 1: Think about that world nineteen oh five, monarchs still ruled

60
00:02:48,719 --> 00:02:51,159
huge parts of the globe. Only what three percent of

61
00:02:51,240 --> 00:02:52,479
US homes had electricity?

62
00:02:52,520 --> 00:02:55,159
Speaker 2: See these filled with the sound of horses, steam trains, yeah.

63
00:02:55,120 --> 00:02:58,680
Speaker 1: Clip clop of carriages, and those first experimental planes had

64
00:02:58,719 --> 00:03:01,039
just barely kind of break taken to the skies.

65
00:03:01,199 --> 00:03:06,159
Speaker 2: Use traveled slowly, telegraph maybe, newspapers taking days or weeks.

66
00:03:05,960 --> 00:03:09,120
Speaker 1: And war casualties tragic of course, but usually measured in

67
00:03:09,199 --> 00:03:11,879
tens of thousands annually, a scale that felt maybe almost

68
00:03:11,919 --> 00:03:13,039
comprehensible globally.

69
00:03:13,120 --> 00:03:14,960
Speaker 2: It was a world with its own problem, sure, but

70
00:03:15,000 --> 00:03:17,520
it had a kind of perceived stability, a rhythm that

71
00:03:17,560 --> 00:03:19,240
had existed for centuries.

72
00:03:19,280 --> 00:03:20,639
Speaker 1: Really yeah, a slower pace.

73
00:03:21,039 --> 00:03:25,800
Speaker 2: And that perspective is just crucial because it highlights this dizzying,

74
00:03:25,960 --> 00:03:30,159
almost unimaginable pace of change that happened next. So I'm

75
00:03:30,199 --> 00:03:33,039
born in nineteen oh five would witness an acceleration that

76
00:03:33,199 --> 00:03:36,800
just it shattered their whole understanding of the world.

77
00:03:36,919 --> 00:03:40,159
Speaker 1: Think about it, horse and buggy to jet engines.

78
00:03:39,919 --> 00:03:45,039
Speaker 2: Candlelight to electric grids, basic physics to unlocking the atom itself, daily.

79
00:03:44,840 --> 00:03:49,719
Speaker 1: Life, transport, communication, how wars were fought. Everything wasn't just evolving,

80
00:03:49,719 --> 00:03:51,199
it was completely overturned.

81
00:03:51,360 --> 00:03:54,479
Speaker 2: It's hard for us today, living with constant innovation, to

82
00:03:54,639 --> 00:03:58,240
really grasp that happening within one person's lifetime.

83
00:03:58,319 --> 00:04:01,479
Speaker 1: And here's where it gets really unsettling. By nineteen forty five,

84
00:04:01,639 --> 00:04:05,199
that same forty year old, they lived through two World.

85
00:04:04,879 --> 00:04:07,120
Speaker 2: Wars, conflicts that redefine the word total.

86
00:04:07,280 --> 00:04:10,439
Speaker 1: They'd have seen twenty four million soldiers dead and a

87
00:04:10,520 --> 00:04:12,520
horrifying fifty million civilians.

88
00:04:12,599 --> 00:04:15,120
Speaker 2: The scale of suffering was just staggering. Prepared to anything

89
00:04:15,159 --> 00:04:15,719
before and.

90
00:04:15,680 --> 00:04:19,879
Speaker 1: Then bam, Suddenly, seemingly overnight, alongside TVs and microwaves and

91
00:04:19,959 --> 00:04:21,000
jet planes.

92
00:04:20,839 --> 00:04:24,639
Speaker 2: Humanity unveils the ultimate terror, nuclear bombs.

93
00:04:24,680 --> 00:04:26,680
Speaker 1: It wasn't just progress anymore, was it. It was an

94
00:04:26,759 --> 00:04:29,680
existential earthquake, shook the foundations of everything.

95
00:04:29,920 --> 00:04:34,720
Speaker 2: Our sources put it powerfully. These innovations, this speed kind

96
00:04:34,720 --> 00:04:37,199
of broke the brains of the people alive back.

97
00:04:37,040 --> 00:04:38,920
Speaker 1: Then, and honestly, looking at it like that, you can

98
00:04:38,959 --> 00:04:41,680
totally see why. It's like the ground just vanished beneath

99
00:04:41,680 --> 00:04:42,040
their feet.

100
00:04:42,160 --> 00:04:45,480
Speaker 2: That phrase broke the brains. It really hits home, doesn't it.

101
00:04:45,480 --> 00:04:49,439
It's more than just fear, It's like profound disorientation. Yeah,

102
00:04:49,839 --> 00:04:53,800
before nineteen forty five, you could maybe feel safe somewhere remote,

103
00:04:54,199 --> 00:04:58,399
but nuclear weapons that illusion just shattered suddenly.

104
00:04:58,680 --> 00:05:02,360
Speaker 1: Nowhere felt safe, not a remote village, not a deep bunker,

105
00:05:02,600 --> 00:05:02,920
not the.

106
00:05:02,920 --> 00:05:05,720
Speaker 2: Edge of space, not the bottom of the ocean, nowhere.

107
00:05:06,279 --> 00:05:09,120
This vulnerability was a global trauma.

108
00:05:08,600 --> 00:05:12,120
Speaker 1: A terrifying realization that we could actually annihilate ourselves and

109
00:05:12,160 --> 00:05:14,560
that power could arrive anywhere, anytime.

110
00:05:14,720 --> 00:05:17,399
Speaker 2: It just fundamentally changed how people thought about security.

111
00:05:17,639 --> 00:05:21,959
Speaker 1: So with this massive shift, this psychological shock, what did

112
00:05:22,000 --> 00:05:24,560
it mean for national security, how do you even protect

113
00:05:24,560 --> 00:05:27,160
a nation when cities can just vanish?

114
00:05:27,199 --> 00:05:31,399
Speaker 2: Well, the implications were, as the sources say, wild, a new,

115
00:05:31,720 --> 00:05:35,839
terrifying consensus started forming in governments. Without nuclear weapons, you

116
00:05:35,920 --> 00:05:39,839
basically stood no chance in the next war. Conventional armies,

117
00:05:40,160 --> 00:05:46,160
no matter how big they risked, being just trampled obsolete overnight.

118
00:05:46,360 --> 00:05:48,279
Speaker 1: So it wasn't about winning battles anymore.

119
00:05:48,399 --> 00:05:52,879
Speaker 2: It was about sheer survival, existential survival. This shift in thinking,

120
00:05:53,279 --> 00:05:57,040
this deep fear of being defenseless, that was the fertile

121
00:05:57,079 --> 00:05:58,439
ground for everything that followed.

122
00:05:58,519 --> 00:06:03,240
Speaker 1: It completely redefined global power, didn't it. Nuclear capability became

123
00:06:03,319 --> 00:06:04,560
the ultimate.

124
00:06:04,240 --> 00:06:05,959
Speaker 2: Currency, absolutely paramount.

125
00:06:06,040 --> 00:06:09,160
Speaker 1: It's important to remember, though, this path, it wasn't totally

126
00:06:09,240 --> 00:06:11,800
set in stone, right. There was a moment, a fleeting.

127
00:06:11,480 --> 00:06:14,879
Speaker 2: One, yeah, nineteen forty six, a brief glimmer where maybe

128
00:06:14,920 --> 00:06:17,040
the nuclear genie could have been put back in the bottle.

129
00:06:17,160 --> 00:06:20,879
Speaker 1: The US, having just used the bomb, proposed the Baruku.

130
00:06:20,560 --> 00:06:22,800
Speaker 2: Plan right to the brand new United Nations, and it

131
00:06:22,800 --> 00:06:25,759
was radical, really. The US offered to eliminate its bombs,

132
00:06:26,000 --> 00:06:28,759
share the tech for peaceful uses only, and set up

133
00:06:28,759 --> 00:06:31,480
an international authority to make sure no one built weapons.

134
00:06:31,519 --> 00:06:35,160
Speaker 1: Ever, again, a chance to stop proliferation right at the start.

135
00:06:35,399 --> 00:06:37,800
A world without this threat was actually on the table

136
00:06:37,959 --> 00:06:41,120
for a moment. But the lure of that power, that

137
00:06:41,160 --> 00:06:43,839
military advantage, it was just too great to let go of.

138
00:06:43,920 --> 00:06:46,560
Speaker 2: Wasn't it seems so the world was still raw from

139
00:06:46,600 --> 00:06:49,600
the war. Trust was low between the US and Soviets.

140
00:06:50,240 --> 00:06:52,879
Giving up that ultimate weapon felt too risky to them.

141
00:06:53,120 --> 00:06:56,600
Speaker 1: Strategic dominance now versus collective piece.

142
00:06:56,360 --> 00:06:59,279
Speaker 2: Later, And well, we know which path was chosen, and.

143
00:06:59,199 --> 00:07:03,839
Speaker 1: With that choice, any hope for that peaceful path just vanished.

144
00:07:04,360 --> 00:07:06,560
Three years later, nineteen forty nine.

145
00:07:06,319 --> 00:07:10,279
Speaker 2: The Soviet Union detonates first lightning their first atomic bomb.

146
00:07:10,160 --> 00:07:12,519
Speaker 1: Which caught the West completely off guard totally.

147
00:07:12,560 --> 00:07:15,439
Speaker 2: The assumption was they were decades behind, that the US

148
00:07:15,480 --> 00:07:16,439
had this huge lead.

149
00:07:16,560 --> 00:07:19,800
Speaker 1: Instead, they'd pulled even stunned everyone, and.

150
00:07:19,759 --> 00:07:21,839
Speaker 2: That shock turned very quickly into raw.

151
00:07:21,720 --> 00:07:25,680
Speaker 1: Fear, and fear makes people and nations do crazy things.

152
00:07:25,800 --> 00:07:27,720
Speaker 2: The whole idea of war, how you win it, just

153
00:07:27,759 --> 00:07:29,000
got flipped upside down again.

154
00:07:29,079 --> 00:07:33,160
Speaker 1: Old strategies, massed armies, geographies suddenly felt kind of pointless.

155
00:07:33,240 --> 00:07:35,680
Speaker 2: Right if your enemy could just fly over and vaporize

156
00:07:35,680 --> 00:07:37,959
your cities, the only answer seemed to be more nukes,

157
00:07:38,399 --> 00:07:41,439
strike faster, harder, more devastatingly.

158
00:07:40,839 --> 00:07:42,879
Speaker 1: Which kicked off the arms race proper.

159
00:07:42,720 --> 00:07:47,800
Speaker 2: Exactly, a spiral fueled by paranoia, distrust, the desperate need

160
00:07:47,839 --> 00:07:48,759
for superiority.

161
00:07:49,120 --> 00:07:51,879
Speaker 1: The numbers tell the story, don't they. Nineteen forty six

162
00:07:52,279 --> 00:07:56,319
Baruch plan time just nine bombs all American. By nineteen

163
00:07:56,439 --> 00:07:59,839
fifty here three hundred, and by nineteen sixty.

164
00:08:00,120 --> 00:08:04,319
Speaker 2: Find twenty thousand each one, multiplying the potential for global catastrophe.

165
00:08:04,360 --> 00:08:06,639
It was a deluge of destructive.

166
00:08:06,079 --> 00:08:08,560
Speaker 1: Power, you know, looking back, the whole thing seems what

167
00:08:08,720 --> 00:08:09,399
pretty daft.

168
00:08:09,480 --> 00:08:11,360
Speaker 2: Actually daft is a good word for it.

169
00:08:11,399 --> 00:08:14,000
Speaker 1: One side builds a bigger bomb, blows it up. Then

170
00:08:14,040 --> 00:08:16,319
the other side feels they have to build something even bigger,

171
00:08:16,360 --> 00:08:17,240
blow that up.

172
00:08:17,240 --> 00:08:21,759
Speaker 2: Endless, dirty, wasteful, just creating more and more horror.

173
00:08:21,439 --> 00:08:25,160
Speaker 1: Which somehow seemed totally logical at the time. Driven by fear,

174
00:08:25,360 --> 00:08:28,720
this warped idea of security that actually made everyone less secure.

175
00:08:28,800 --> 00:08:31,040
Speaker 2: Precisely, it looked rational on the surface, right, if they

176
00:08:31,079 --> 00:08:33,360
build bigger, we have to build bigger. But it locked

177
00:08:33,360 --> 00:08:36,480
everyone into this security dilemma. Trying to be safer just

178
00:08:36,519 --> 00:08:39,440
made the other side feel less safe fueling more escalation,

179
00:08:39,879 --> 00:08:42,879
a global prisoner's dilemma, Yeah, where the rational choice for

180
00:08:42,919 --> 00:08:45,320
each side led to a collectively insane outcome.

181
00:08:45,639 --> 00:08:50,559
Speaker 1: Trillions spent, thousands of the smartest people mobilized, all to

182
00:08:50,679 --> 00:08:52,919
show off how well they could destroy humanity.

183
00:08:53,240 --> 00:08:55,240
Speaker 2: The belief was fear had to be met with even

184
00:08:55,279 --> 00:08:56,639
greater horror, and there was.

185
00:08:56,600 --> 00:08:59,080
Speaker 1: One man in particular who knew exactly how to make

186
00:08:59,120 --> 00:09:03,399
those horrors real. Ah. Yes, Edward Teller, a brilliant Hungarian

187
00:09:03,440 --> 00:09:07,480
theoretical physicist, part of that wave of scientists who fled Europe.

188
00:09:07,519 --> 00:09:09,679
Speaker 2: He was there right at the beginning. Yeah, grasped the

189
00:09:09,679 --> 00:09:12,639
potential efficient early on key player and building the first

190
00:09:12,639 --> 00:09:13,240
A bombs.

191
00:09:13,360 --> 00:09:15,960
Speaker 1: But for Teller, those bombs, the ones that ended World

192
00:09:16,000 --> 00:09:18,320
War Two, they just warn enough.

193
00:09:18,440 --> 00:09:21,480
Speaker 2: No, he saw them as just a first step, an

194
00:09:21,480 --> 00:09:22,519
appetizer almost.

195
00:09:22,639 --> 00:09:26,759
Speaker 1: He was driven by this, this uncompromising desire for security,

196
00:09:26,960 --> 00:09:28,879
ready to pay any price, it seemed.

197
00:09:28,639 --> 00:09:32,240
Speaker 2: And he believed, really believed that the answer to fear

198
00:09:32,360 --> 00:09:35,879
was just ever larger bombs, more power.

199
00:09:35,679 --> 00:09:38,399
Speaker 1: Which was a pretty controversial idea even back then, right

200
00:09:38,440 --> 00:09:40,840
the A bomb itself was still horrifyingly new.

201
00:09:41,039 --> 00:09:44,480
Speaker 2: Absolutely many scientists, even his former colleagues from the Manhattan

202
00:09:44,480 --> 00:09:48,440
Project were appalled. They saw it as dangerous, maybe even mad,

203
00:09:48,919 --> 00:09:51,120
questioned the morality of it all, But tell.

204
00:09:50,919 --> 00:09:54,240
Speaker 1: Her he didn't seem to care much about their qualms.

205
00:09:53,840 --> 00:09:56,919
Speaker 2: Not one bit. He was relentless, a force of.

206
00:09:56,879 --> 00:10:01,039
Speaker 1: Nature, constantly lobbying politicians, playing on their fears of the Soviets,

207
00:10:01,080 --> 00:10:03,519
pushing for more devastating weapons.

208
00:10:03,080 --> 00:10:07,159
Speaker 2: And is timing well who was oftened perfect for his agenda.

209
00:10:07,519 --> 00:10:10,120
He fit right into that post Soviet bomb.

210
00:10:09,840 --> 00:10:13,799
Speaker 1: Paranoia, promising ultimate security through ultimate destruction.

211
00:10:14,360 --> 00:10:17,799
Speaker 2: And in that climate, the military establishment was deeply alarmed

212
00:10:17,840 --> 00:10:22,600
by Soviet progress. They saw teller Is offering a solution, however.

213
00:10:22,360 --> 00:10:24,919
Speaker 1: Extreme, so they basically gave him a blank check.

214
00:10:25,039 --> 00:10:30,080
Speaker 2: Pretty much unprecedented support, funding resources to bring his biggest,

215
00:10:30,200 --> 00:10:32,080
most destructive ideas to life.

216
00:10:32,120 --> 00:10:34,840
Speaker 1: And it only took him a few years. The hydrogen bomb,

217
00:10:34,879 --> 00:10:35,919
the super.

218
00:10:35,639 --> 00:10:39,279
Speaker 2: Which just changed the scale completely from kilotons to megatons,

219
00:10:39,320 --> 00:10:42,080
thousands of tons of TNT equivalent to billions.

220
00:10:42,320 --> 00:10:45,440
Speaker 1: So how does this thing even work? It sounds mind bending.

221
00:10:45,159 --> 00:10:48,679
Speaker 2: It is pretty complex, but the core idea, it's so powerful,

222
00:10:48,679 --> 00:10:50,919
and he's a regular atom bomb just to trigger.

223
00:10:50,600 --> 00:10:53,080
Speaker 1: It, a bomb inside a bomb essentially, Yeah.

224
00:10:53,000 --> 00:10:55,519
Speaker 2: A two stage device. You've got your fish and nuke

225
00:10:55,639 --> 00:10:58,200
the primary, then next to it a capsule of fusion

226
00:10:58,200 --> 00:11:01,600
fuel the secondary. Yeah, all wrap and special materials. Okay,

227
00:11:01,759 --> 00:11:04,440
So when the primary a bomb goes off, it releases

228
00:11:04,480 --> 00:11:07,679
this stupendous amount of X rays and radiation pressure. These

229
00:11:07,720 --> 00:11:11,960
are channeled onto the fusion capsule, crushing it inwards incredibly violently.

230
00:11:12,399 --> 00:11:15,320
Radiation implosion, they call it, right. And that compression gets

231
00:11:15,360 --> 00:11:18,399
the fusion fuel, usually lithium deuteride, so hot and dense

232
00:11:18,440 --> 00:11:20,720
that for a tiny fraction of a second you basically

233
00:11:20,759 --> 00:11:23,799
create the conditions inside a star.

234
00:11:23,759 --> 00:11:25,879
Speaker 1: A star on Earth exactly.

235
00:11:26,240 --> 00:11:29,720
Speaker 2: Fusion happens. Light atoms fuse into heavier ones, releasing a

236
00:11:29,720 --> 00:11:31,679
whole different order of magnitude of energy.

237
00:11:31,960 --> 00:11:35,240
Speaker 1: The H bomb explosion, the first test ivy Mic nineteen

238
00:11:35,279 --> 00:11:36,519
fifty two. What happened and.

239
00:11:36,480 --> 00:11:38,840
Speaker 2: Just a race of Pacific Island. Yeah, a luge lab

240
00:11:39,039 --> 00:11:42,480
gone left a crater over mile wide, unbelievable. Two years later,

241
00:11:42,600 --> 00:11:46,679
Castle Bravo even bigger, a thousand times Hiroshima. The mushroom

242
00:11:46,720 --> 00:11:50,000
cloud went twenty five miles high. Unexpected fallout spread far

243
00:11:50,039 --> 00:11:50,559
and wide.

244
00:11:50,639 --> 00:11:52,159
Speaker 1: The world must have recoiled in.

245
00:11:52,200 --> 00:11:57,120
Speaker 2: Horror they did, realizing that total annihilation was now genuinely possible.

246
00:11:57,360 --> 00:11:59,240
We built something that could end everything.

247
00:11:59,360 --> 00:12:02,240
Speaker 1: Yet tell her, he celebrated, He did.

248
00:12:02,600 --> 00:12:06,120
Speaker 2: In just two years, He'd enabled warheads one hundred times

249
00:12:06,159 --> 00:12:09,559
more powerful. He'd, as the source says, stolen the nuclear

250
00:12:09,600 --> 00:12:10,559
fire from the gods.

251
00:12:10,879 --> 00:12:12,600
Speaker 1: But even that wasn't enough for him.

252
00:12:12,679 --> 00:12:16,159
Speaker 2: Nope, he insisted, it still wasn't enough. His dream was

253
00:12:16,200 --> 00:12:21,000
a bomb of almost unlimited power, truly apocalyptic.

254
00:12:20,279 --> 00:12:22,919
Speaker 1: And his timing was good again unfortunately.

255
00:12:22,360 --> 00:12:26,080
Speaker 2: Because the Soviets then detonated their own age bomb, sparking

256
00:12:26,080 --> 00:12:29,799
another wave of fear, cementing the perceived need for even more.

257
00:12:29,799 --> 00:12:33,039
Speaker 1: Which brings us finally to Project Sundial.

258
00:12:32,720 --> 00:12:35,320
Speaker 2: Right, the bomb to make all other bombs irrelevant, the

259
00:12:35,399 --> 00:12:37,519
ultimate weapon, the endgame.

260
00:12:37,360 --> 00:12:39,240
Speaker 1: Teller just skipped right to the end in the no

261
00:12:39,320 --> 00:12:40,840
more intrumental steps exactly.

262
00:12:40,840 --> 00:12:45,759
Speaker 2: He wanted a world destroyer, something so unbelievably destructive, so terrifying,

263
00:12:46,000 --> 00:12:50,200
it would make the whole game of nuclear braakmanship pointless.

264
00:12:49,759 --> 00:12:54,039
Speaker 1: The ultimate deterrent, in his mind, paralyze any enemy with fear.

265
00:12:54,360 --> 00:12:58,799
Speaker 2: And almost everything about Sundial is still classified, but we

266
00:12:58,879 --> 00:13:02,679
know work actually began tests were planned. It moved beyond

267
00:13:02,879 --> 00:13:03,720
just theory.

268
00:13:03,639 --> 00:13:07,600
Speaker 1: And the concept itself is just shillingly absurd. It wouldn't

269
00:13:07,600 --> 00:13:09,159
be delivered by a missile or bomber.

270
00:13:09,360 --> 00:13:13,639
Speaker 2: No, the idea was terrifyingly simple. A backyard bomb.

271
00:13:13,840 --> 00:13:14,879
Speaker 1: A backyard bomb.

272
00:13:15,039 --> 00:13:17,240
Speaker 2: The logic was stark. If it can destroy the world,

273
00:13:17,320 --> 00:13:19,960
why bother moving it? Put it in your own territory.

274
00:13:20,360 --> 00:13:21,480
Its target is everything.

275
00:13:21,679 --> 00:13:25,120
Speaker 1: So where would they put it? Underground? On an island?

276
00:13:25,200 --> 00:13:27,720
Speaker 2: We don't know the specifics, maybe deep in the US interior,

277
00:13:28,000 --> 00:13:31,320
maybe remote island, maybe a ship. But the uncertainty just

278
00:13:31,399 --> 00:13:32,759
highlights how insane it was.

279
00:13:32,840 --> 00:13:34,559
Speaker 1: And Teller knew exactly what he was proposing.

280
00:13:34,600 --> 00:13:38,399
Speaker 2: Oh absolutely. The rationale was ultimate de terrens, non negotiable,

281
00:13:38,799 --> 00:13:41,759
attack US or our allies, and we destroy the world period.

282
00:13:41,960 --> 00:13:44,000
Speaker 1: Technically, how would it work? Was it new physics?

283
00:13:44,600 --> 00:13:47,799
Speaker 2: Probably not entirely new physics, More like an audacious scaling

284
00:13:47,879 --> 00:13:51,120
up of the H bomb principle, a nuclear matrioshka.

285
00:13:50,559 --> 00:13:52,320
Speaker 1: Doll layers upon layers, Yeah.

286
00:13:52,279 --> 00:13:57,000
Speaker 2: Nested thermonuclear stages, each igniting the next, multiplying the yield exponentially, and.

287
00:13:56,919 --> 00:14:00,240
Speaker 1: The scale two thousand tons, like a cargo.

288
00:14:00,639 --> 00:14:04,720
Speaker 2: At least exploding with the power of ten billion tons

289
00:14:04,720 --> 00:14:07,519
of TNT, a number that just breaks your brain.

290
00:14:07,600 --> 00:14:09,440
Speaker 1: Let's try to picture it exploding in Nevada.

291
00:14:09,559 --> 00:14:15,000
Speaker 2: Okay, Imagine a fireball instantly fifty kilometers across, bigger than

292
00:14:15,000 --> 00:14:17,360
the horizon. You can see a searing.

293
00:14:17,039 --> 00:14:19,320
Speaker 1: Miniature sun, radiating heat at light speed.

294
00:14:19,559 --> 00:14:24,360
Speaker 2: Everything within four hundred kilometers instantly on fire, Trees, houses,

295
00:14:24,720 --> 00:14:27,759
people just consumed, and.

296
00:14:27,679 --> 00:14:29,960
Speaker 1: The Earth's curve wouldn't even protect you initially.

297
00:14:30,039 --> 00:14:33,200
Speaker 2: Nope, the desert around it would melt into glass, a

298
00:14:33,279 --> 00:14:36,639
huge field of glass, and the blast wave unimaginable force.

299
00:14:36,879 --> 00:14:41,000
The atmosphere above punched into space, a magnitude nine earthquake

300
00:14:41,120 --> 00:14:41,759
ripping across the.

301
00:14:41,840 --> 00:14:44,799
Speaker 1: UA, carrying everything apart, and the sound.

302
00:14:44,440 --> 00:14:48,039
Speaker 2: A roar echoing around the entire globe, a planetary death knell.

303
00:14:48,120 --> 00:14:51,159
Speaker 1: It's hard to truly visualize that level of destruction, it

304
00:14:51,200 --> 00:14:51,600
really is.

305
00:14:51,639 --> 00:14:53,840
Speaker 2: The audacity is almost as terrifying as the weapon.

306
00:14:53,879 --> 00:14:54,759
Speaker 1: And that's just the start.

307
00:14:54,840 --> 00:14:58,080
Speaker 2: Right the aftermatha oh yeah, forces across North America, burning

308
00:14:58,120 --> 00:15:01,679
for weeks, adding tons of soot to the radioactive fallout.

309
00:15:01,360 --> 00:15:05,360
Speaker 1: Creating these thick toxic clouds shrouding the world.

310
00:15:05,679 --> 00:15:08,120
Speaker 2: It's not like a normal nuclear war. It's like a

311
00:15:08,120 --> 00:15:14,159
supervolcano or an asteroid strike, an immediate global environmental.

312
00:15:13,399 --> 00:15:15,720
Speaker 1: Collapse, triggering a nuclear winter.

313
00:15:15,720 --> 00:15:22,679
Speaker 2: Exactly, sunlight blocked, global temperatures dropping maybe ten degrees c suddenly, icy.

314
00:15:22,600 --> 00:15:26,360
Speaker 1: Darkness, water contaminated crops failing everywhere.

315
00:15:26,440 --> 00:15:30,960
Speaker 2: Most people in the world would die, radiation starvation, societal collapse.

316
00:15:31,200 --> 00:15:34,919
Speaker 1: So congratulations, you won a victory with no survivors, just

317
00:15:34,960 --> 00:15:38,000
a dead planet. So the good news, if you can

318
00:15:38,039 --> 00:15:41,240
call it, that Sundell wasn't actually built right.

319
00:15:41,399 --> 00:15:44,480
Speaker 2: Details are still top secret, but we know scientists reacted

320
00:15:44,519 --> 00:15:48,279
with horror. Politicians who were briefed disbelief, deep unease.

321
00:15:48,399 --> 00:15:50,759
Speaker 1: Even the military thought it was a bit much.

322
00:15:51,159 --> 00:15:53,919
Speaker 2: Yeah, in the already insane world of nukes, this is

323
00:15:53,960 --> 00:15:55,799
just too far, a crime against.

324
00:15:55,600 --> 00:15:59,600
Speaker 1: Humanity, strategically bankrupt, too right. Using it guarantees your own destruction.

325
00:15:59,360 --> 00:16:02,720
Speaker 2: Absolutely, and it had other huge problems, no flexibility. What's

326
00:16:02,759 --> 00:16:05,200
the trigger? A border scarmish, a coup?

327
00:16:05,360 --> 00:16:07,399
Speaker 1: Would you really end the world for that? How do

328
00:16:07,440 --> 00:16:10,120
you protect an ally with a bomb that kills them too?

329
00:16:10,440 --> 00:16:13,759
Speaker 2: It's deterrence that destroys the very thing you're trying to protect.

330
00:16:14,000 --> 00:16:15,200
A total paradox.

331
00:16:15,600 --> 00:16:19,240
Speaker 1: But here's the uncomfortable question, isn't it While that specific

332
00:16:19,279 --> 00:16:20,559
bomb wasn't built.

333
00:16:20,720 --> 00:16:24,080
Speaker 2: Humanity still kind of did build it, just differently.

334
00:16:24,240 --> 00:16:28,120
Speaker 1: Yeah, Peete, Cold War over seventy thousand nukes total and.

335
00:16:28,080 --> 00:16:31,559
Speaker 2: Even today around twelve thousand, still easily enough to destroy

336
00:16:31,639 --> 00:16:33,080
civilization many times over.

337
00:16:33,200 --> 00:16:35,799
Speaker 1: So instead of one big world burner, we.

338
00:16:35,799 --> 00:16:39,799
Speaker 2: Built tens of thousands of nukes of all sizes, tactical, strategic,

339
00:16:40,240 --> 00:16:43,879
hidden in subs, silos, bombers ready.

340
00:16:43,639 --> 00:16:48,080
Speaker 1: To go, not one button, but a sprawling, distributed doomsday machine.

341
00:16:47,679 --> 00:16:52,159
Speaker 2: Which sounds weirdly more reasonable to some people having smaller

342
00:16:52,200 --> 00:16:53,559
tactical options.

343
00:16:53,159 --> 00:16:55,559
Speaker 1: But maybe that makes them more dangerous, more likely to

344
00:16:55,559 --> 00:16:56,480
actually be used.

345
00:16:56,600 --> 00:16:59,039
Speaker 2: That's the fear. If leaders think they can risk using

346
00:16:59,080 --> 00:17:02,480
a smaller nuke, maybe believing it won't escalate, they might

347
00:17:02,519 --> 00:17:03,080
actually do it.

348
00:17:03,120 --> 00:17:05,240
Speaker 1: And we have no idea what chain reaction that could start.

349
00:17:05,319 --> 00:17:08,640
Speaker 2: Exactly one small strike could spiral into a full exchange

350
00:17:08,880 --> 00:17:11,400
achieving Sundal's outcome anyway, just step by step.

351
00:17:11,680 --> 00:17:14,519
Speaker 1: So the difference between Project sun Dial and what we

352
00:17:14,559 --> 00:17:18,119
have now, maybe it's not that big in terms of

353
00:17:18,160 --> 00:17:19,000
the ultimate threat.

354
00:17:19,240 --> 00:17:22,680
Speaker 2: Arguably, no, we didn't build a doomsday bomb, but we

355
00:17:22,799 --> 00:17:27,279
absolutely built a doomsday machine, a system holding the same power.

356
00:17:27,119 --> 00:17:29,720
Speaker 1: And we live with that potential every single day.

357
00:17:29,799 --> 00:17:33,279
Speaker 2: It's chilling, and today, well disturbingly, it looks like we

358
00:17:33,359 --> 00:17:34,839
might be on the verge of another.

359
00:17:34,640 --> 00:17:39,119
Speaker 1: Arms race, to us spending trillions on modernization, China rapidly

360
00:17:39,160 --> 00:17:40,319
expanding its arsenal.

361
00:17:40,480 --> 00:17:43,160
Speaker 2: It's a worrying echo of the past, isn't it the

362
00:17:43,160 --> 00:17:46,960
same dynamics of fear, distrust, escalation that led to sun dial.

363
00:17:47,039 --> 00:17:49,440
Speaker 1: We've managed to avoid the worst so far decades of

364
00:17:49,440 --> 00:17:53,400
Cold War close calls incredible restraint, maybe luck.

365
00:17:53,559 --> 00:17:56,480
Speaker 2: But as one source put it, if aliens visited saw

366
00:17:56,519 --> 00:17:58,920
our nukes, they might just ask if we're okay and

367
00:17:58,960 --> 00:17:59,480
need a hug.

368
00:17:59,599 --> 00:18:01,880
Speaker 1: It's a darkly funny way to put it, but it

369
00:18:01,960 --> 00:18:05,519
highlights the absurdity, doesn't it? Our security guaranteed by our

370
00:18:05,559 --> 00:18:07,640
ability to destroy ourselves.

371
00:18:07,240 --> 00:18:09,599
Speaker 2: Which raises that big question for all of us as

372
00:18:09,599 --> 00:18:12,200
a species. Do we really want to keep living like this?

373
00:18:12,559 --> 00:18:14,319
Ready to destroy ourselves instantly?

374
00:18:14,480 --> 00:18:15,640
Speaker 1: Is this the best we can do?

375
00:18:16,119 --> 00:18:18,720
Speaker 2: Science itself isn't good or bad? Is it? It's a

376
00:18:18,759 --> 00:18:20,799
tool reflects our curiosity.

377
00:18:20,839 --> 00:18:24,279
Speaker 1: The responsibility lies with us how we use that power.

378
00:18:23,960 --> 00:18:27,119
Speaker 2: That knowledge and the story of Sundial. It's such a

379
00:18:27,160 --> 00:18:30,480
stark reminder of the power we have and the immense

380
00:18:30,519 --> 00:18:33,759
responsibility that comes with it. A mirror to our fears

381
00:18:33,759 --> 00:18:35,039
and ambitions.

382
00:18:34,640 --> 00:18:37,599
Speaker 1: A crossreads we navigated, but the shadow is still there.

383
00:18:37,799 --> 00:18:40,000
Speaker 2: So what stands out to you listening to this? How

384
00:18:40,039 --> 00:18:43,319
do we balance that real need for security with the

385
00:18:43,400 --> 00:18:45,200
catastrophic cost of these weapons.

386
00:18:45,279 --> 00:18:47,559
Speaker 1: It's a question that just keeps echoing, doesn't it. From

387
00:18:47,680 --> 00:18:51,720
sun Dial, secret meetings to today's headlines. It demands our attention,

388
00:18:52,000 --> 00:18:52,759
our thought.

389
00:18:52,720 --> 00:18:55,359
Speaker 2: Maybe a renewed effort to find other paths.

390
00:18:55,400 --> 00:18:57,359
Speaker 1: Well, thank you for joining us on this natural, well

391
00:18:57,400 --> 00:19:02,400
incredibly important and frankly chilling dive into Projects Sundial and

392
00:19:02,440 --> 00:19:05,039
its enduring legacy. We really hope it leaves you with

393
00:19:05,079 --> 00:19:06,279
a lot to think about.

394
00:19:06,039 --> 00:19:08,200
Speaker 2: To question, and a deeper understanding of the world we

395
00:19:08,240 --> 00:19:08,519
live in.

396
00:19:08,839 --> 00:19:13,519
Speaker 1: Until next time, keep exploring, keep questioning, and let's try

397
00:19:13,559 --> 00:19:16,960
to use our curiosity for something positive, something that builds,

398
00:19:17,039 --> 00:19:19,599
not destroys.
