1
00:00:02,168 --> 00:00:03,501
Massive structures

2
00:00:03,626 --> 00:00:06,543
lost beneath the waves
for thousands of years.

3
00:00:07,918 --> 00:00:09,293
Sunken continents

4
00:00:09,418 --> 00:00:12,210
that were home
to advanced civilizations...

5
00:00:13,418 --> 00:00:18,126
...and a remote mountain lake
filled with gold treasure.

6
00:00:20,085 --> 00:00:22,960
For as long as
man has roamed the Earth,

7
00:00:23,085 --> 00:00:25,501
we've also explored
the world's oceans

8
00:00:25,626 --> 00:00:28,418
in order to find out
what lies below.

9
00:00:28,543 --> 00:00:33,501
Is the planet's vast underwater
world hiding profound secrets

10
00:00:33,626 --> 00:00:38,210
in the silent expanse
of cold and darkness?

11
00:00:38,293 --> 00:00:42,876
What can the depths of the sea
tell us about our human nature

12
00:00:43,001 --> 00:00:45,251
and perhaps
a lost human history?

13
00:00:45,418 --> 00:00:49,543
Well, that is what
we'll try and find out.

14
00:01:08,585 --> 00:01:11,876
Billionaire and underwater
explorer Victor Vescovo

15
00:01:12,001 --> 00:01:14,751
boards an advanced
deep-sea submersible

16
00:01:14,918 --> 00:01:17,210
known as the Limiting Factor

17
00:01:17,335 --> 00:01:21,168
and descends underwater.

18
00:01:22,168 --> 00:01:25,210
His mission is to explore
the Challenger Deep,

19
00:01:25,293 --> 00:01:29,585
an underwater valley that is
the deepest point on the planet.

20
00:01:31,293 --> 00:01:32,418
I was the fourth person to dive

21
00:01:32,543 --> 00:01:33,960
to the bottom
of Challenger Deep.

22
00:01:34,085 --> 00:01:35,376
Within the first
thousand meters,

23
00:01:35,501 --> 00:01:37,376
it goes from being brilliant
sunshine in the Pacific

24
00:01:37,501 --> 00:01:39,626
to pretty much fully black.

25
00:01:40,918 --> 00:01:44,835
So you descend in the water
column, as we call it,

26
00:01:44,918 --> 00:01:47,376
for up to four hours,

27
00:01:47,460 --> 00:01:50,210
steadily going down, watching
that depthometer creeping,

28
00:01:50,335 --> 00:01:51,376
creeping, creeping.

29
00:01:51,460 --> 00:01:53,376
And you get to the bottom
and then you

30
00:01:53,460 --> 00:01:55,501
check in with the surface,
tell them that you're ok.

31
00:01:59,376 --> 00:02:01,876
At that point, it takes seven
seconds for the transmission

32
00:02:02,043 --> 00:02:03,418
to actually get to the surface

33
00:02:03,543 --> 00:02:05,793
and seven seconds
for it to go down.

34
00:02:07,251 --> 00:02:10,210
It's such an incredible
feeling of relief

35
00:02:10,376 --> 00:02:12,293
and a sense of incredible
achievement that,

36
00:02:12,418 --> 00:02:13,876
"Oh, my gosh,
we actually did it."

37
00:02:15,168 --> 00:02:16,543
Challenger Deep

38
00:02:16,668 --> 00:02:21,210
is the most deep, dark and
dangerous place on the planet.

39
00:02:22,293 --> 00:02:24,876
When you get to the bottom,
the pressure is

40
00:02:25,001 --> 00:02:26,293
the equivalent of having

41
00:02:26,418 --> 00:02:29,376
200 747s
stacked on top of you.

42
00:02:29,460 --> 00:02:31,668
Unimaginable
crush pressure there.

43
00:02:33,126 --> 00:02:36,376
You need a properly
engineered submersible

44
00:02:36,501 --> 00:02:39,543
that can go down,
withstand the pressure,

45
00:02:39,626 --> 00:02:40,460
stay down there,

46
00:02:40,585 --> 00:02:43,168
and continue
to explore these depths.

47
00:02:45,335 --> 00:02:47,085
To get to these locations,

48
00:02:47,210 --> 00:02:48,376
it's an extraordinary
undertaking

49
00:02:48,501 --> 00:02:49,668
and it should be celebrated.

50
00:02:49,751 --> 00:02:52,335
They are incredibly
difficult to get to,

51
00:02:52,460 --> 00:02:55,460
they're extremely dangerous,
they're very hostile to people.

52
00:02:55,585 --> 00:02:56,710
We don't belong down there.

53
00:02:59,168 --> 00:03:00,918
The ocean is a vast expanse

54
00:03:01,043 --> 00:03:03,835
that is almost
unimaginable in scope.

55
00:03:05,418 --> 00:03:07,126
And although humans
have been traveling

56
00:03:07,251 --> 00:03:09,793
across the high seas
for thousands of years,

57
00:03:09,918 --> 00:03:12,918
we still only know
a fraction of what lies

58
00:03:13,043 --> 00:03:14,918
beneath the waves.

59
00:03:16,668 --> 00:03:17,960
The most important
thing I think

60
00:03:18,085 --> 00:03:21,168
I try to get people to realize
is that the ocean is big.

61
00:03:21,293 --> 00:03:23,210
I mean, really big.

62
00:03:24,418 --> 00:03:26,376
Bigger than you can
put your head around.

63
00:03:26,501 --> 00:03:29,835
It is 70% of planet Earth.

64
00:03:29,960 --> 00:03:31,626
And it's three-dimensional.

65
00:03:31,751 --> 00:03:34,251
It's not a two-dimensional
surface like the land is.

66
00:03:34,418 --> 00:03:36,793
And so, 80% of it
is still completely

67
00:03:36,918 --> 00:03:38,626
unmapped and unexplored.

68
00:03:40,751 --> 00:03:41,793
The deep sea

69
00:03:41,918 --> 00:03:44,293
remains the last great frontier

70
00:03:44,418 --> 00:03:46,001
for us as a species.

71
00:03:47,585 --> 00:03:50,126
We know way more about
the surface of the Moon,

72
00:03:50,251 --> 00:03:52,126
way more about the surface
of the other planets

73
00:03:52,251 --> 00:03:53,835
than we do the deepest spots

74
00:03:53,918 --> 00:03:55,335
in the ocean.

75
00:03:55,460 --> 00:03:58,293
It's a mystery we've just
started to unravel.

76
00:03:59,793 --> 00:04:02,376
The allure of the deep sea
is that it holds something

77
00:04:02,501 --> 00:04:04,251
in everyone's imagination.

78
00:04:04,376 --> 00:04:07,251
Not fully knowing what is there

79
00:04:07,376 --> 00:04:09,751
enables everyone to come up
with their own vision

80
00:04:09,876 --> 00:04:11,376
of what might be there.

81
00:04:12,668 --> 00:04:15,126
What creatures
might live down there?

82
00:04:15,251 --> 00:04:17,793
Might there be
sunken ships and gold,

83
00:04:17,918 --> 00:04:19,376
and where might that be?

84
00:04:20,335 --> 00:04:22,960
That is what
sparks the curiosity

85
00:04:23,085 --> 00:04:25,835
that we need to keep exploring

86
00:04:25,918 --> 00:04:28,710
and to keep investigating
what's down there,

87
00:04:28,835 --> 00:04:29,751
what's out there.

88
00:04:31,043 --> 00:04:33,335
The recent dives
to the bottom of the ocean

89
00:04:33,418 --> 00:04:37,376
have shed new light into
the darkness of its depths.

90
00:04:37,501 --> 00:04:41,876
But these voyages are just
the latest chapter in mankind's

91
00:04:42,043 --> 00:04:45,710
long quest to uncover what
secrets are held in the seas.

92
00:04:45,835 --> 00:04:48,876
In fact, our fascination
with the ocean

93
00:04:49,001 --> 00:04:51,293
goes back thousands of years.

94
00:04:52,751 --> 00:04:54,543
LYNNE Mc
Throughout history

95
00:04:54,668 --> 00:04:56,710
and cross-culturally as well,

96
00:04:56,835 --> 00:04:59,793
we see a really consistent
pattern of belief

97
00:04:59,918 --> 00:05:04,501
that under the water
is an entirely other world...

98
00:05:06,126 --> 00:05:08,043
...full of creatures

99
00:05:08,168 --> 00:05:11,751
like a Kraken or a Leviathan.

100
00:05:11,918 --> 00:05:14,085
And it's not just oceans.

101
00:05:14,210 --> 00:05:18,918
Lakes are always populated
with these monstrous creatures,

102
00:05:19,043 --> 00:05:21,751
like the Loch Ness Monster.

103
00:05:21,876 --> 00:05:23,126
The message we get

104
00:05:23,251 --> 00:05:25,710
is that no body
of water is safe.

105
00:05:27,168 --> 00:05:30,418
The understandings of the seas
and oceans over time

106
00:05:30,543 --> 00:05:32,751
has changed dramatically.

107
00:05:34,210 --> 00:05:36,710
The ocean was basically seen

108
00:05:36,835 --> 00:05:39,210
by seafaring people,
like the ancient Greeks were

109
00:05:39,335 --> 00:05:40,626
or ancient Phoenicians were...

110
00:05:41,585 --> 00:05:44,876
...as the big, bad black sea.

111
00:05:44,960 --> 00:05:45,960
They didn't have the ships

112
00:05:46,085 --> 00:05:47,835
to go against
the currents and the winds.

113
00:05:47,918 --> 00:05:50,001
And if you sailed
far enough, you'd die.

114
00:05:52,293 --> 00:05:54,460
For so long, no one really knew

115
00:05:54,585 --> 00:05:57,793
what the extent of the oceans
were, what's under them.

116
00:05:57,918 --> 00:06:01,835
Even in the time of Columbus,
late 15th century,

117
00:06:01,960 --> 00:06:03,876
people were worried,

118
00:06:03,960 --> 00:06:05,960
some people thought
the Earth was flat,

119
00:06:06,085 --> 00:06:09,210
that you could literally
get to the end of the ocean

120
00:06:09,335 --> 00:06:11,001
and fall off the edge.

121
00:06:13,251 --> 00:06:18,085
Humanity has always been humbled
by the vast power of the ocean.

122
00:06:18,210 --> 00:06:22,751
But during the scientific
revolution in the 16th century,

123
00:06:22,876 --> 00:06:25,376
we started to get
a better understanding

124
00:06:25,501 --> 00:06:27,126
of the underwater world.

125
00:06:28,418 --> 00:06:32,460
In 1521, Portuguese explorer
Ferdinand Magellan

126
00:06:32,585 --> 00:06:36,126
attempted to measure the depth
of the ocean by attaching a line

127
00:06:36,251 --> 00:06:39,793
to a cannonball and tossing it
over the side of his ship.

128
00:06:41,751 --> 00:06:45,001
After lowering
the cannonball 2,400 feet,

129
00:06:45,085 --> 00:06:49,918
Magellan declared that
the ocean was immeasurably deep.

130
00:06:51,668 --> 00:06:54,710
Magellan went out and tried to
measure the depth of the oceans.

131
00:06:54,793 --> 00:06:57,168
He wasn't largely
successful with that,

132
00:06:57,293 --> 00:06:58,418
but it sort of opened
the door that,

133
00:06:58,543 --> 00:06:59,793
wow, this is really deep

134
00:06:59,918 --> 00:07:01,835
and we need to do
more exploration.

135
00:07:03,251 --> 00:07:05,376
That was furthered later

136
00:07:05,501 --> 00:07:10,293
with the HMS Challenger
expedition in the 1870s

137
00:07:10,418 --> 00:07:12,543
that went all the way
around the world

138
00:07:12,710 --> 00:07:14,585
to explore the deep oceans.

139
00:07:14,710 --> 00:07:18,376
And the most significant thing
it found was the deepest part,

140
00:07:18,543 --> 00:07:20,585
which is the Challenger Deep,

141
00:07:20,751 --> 00:07:22,835
which was named
after the expedition.

142
00:07:24,043 --> 00:07:27,376
Over time there became more
of a curiosity to the oceans.

143
00:07:27,543 --> 00:07:30,126
To want to go down
and to be able to go down to,

144
00:07:30,251 --> 00:07:31,835
to see what was there.

145
00:07:33,751 --> 00:07:34,876
In the 20th century,

146
00:07:35,001 --> 00:07:37,126
the development
of undersea submersibles

147
00:07:37,251 --> 00:07:39,251
ushered in a new era

148
00:07:39,418 --> 00:07:43,001
of unprecedented
underwater exploration.

149
00:07:44,626 --> 00:07:47,626
The evolution of a deep
ocean submersible started

150
00:07:47,751 --> 00:07:49,876
in 1930 when
a bathysphere was created,

151
00:07:49,960 --> 00:07:54,710
where a man was put inside
of a, essentially, a vessel...

152
00:07:56,251 --> 00:07:59,543
...and dipped down into
the ocean held by a tether.

153
00:07:59,710 --> 00:08:02,376
That was furthered later

154
00:08:02,501 --> 00:08:05,710
by the bathyscaphe in 1960,

155
00:08:05,835 --> 00:08:08,251
the Trieste, which took
Don Walsh and Jacques Piccard

156
00:08:08,418 --> 00:08:10,293
to the bottom
of the Challenger Deep

157
00:08:10,418 --> 00:08:12,043
for the first time ever.

158
00:08:13,335 --> 00:08:16,085
Today, underwater
archaeologists and explorers

159
00:08:16,251 --> 00:08:19,835
are using the latest
submersible technology

160
00:08:19,960 --> 00:08:22,543
to try to unravel
the mysteries that lie

161
00:08:22,626 --> 00:08:24,043
within the ocean.

162
00:08:24,210 --> 00:08:25,793
And many experts believe

163
00:08:25,918 --> 00:08:28,210
that they are on the cusp
of making dramatic

164
00:08:28,335 --> 00:08:30,960
new discoveries on the seafloor.

165
00:08:33,043 --> 00:08:35,001
My hopes for ocean
exploration in the near term

166
00:08:35,085 --> 00:08:38,876
is to bring
the very deep places,

167
00:08:39,001 --> 00:08:41,501
the very dangerous places
to a point of accessibility

168
00:08:41,626 --> 00:08:43,335
where we can take any
scientists down to them

169
00:08:43,418 --> 00:08:44,543
to explore them.

170
00:08:46,085 --> 00:08:48,710
Also, there's a huge
project underway

171
00:08:48,793 --> 00:08:51,585
called the 2030
Seafloor Initiative,

172
00:08:51,710 --> 00:08:53,710
where a bunch
of different scientists

173
00:08:53,793 --> 00:08:55,001
and people like myself,

174
00:08:55,085 --> 00:08:57,085
we're trying to help
map the seafloor.

175
00:08:59,126 --> 00:09:01,543
The Seabed 2030 Initiative

176
00:09:01,668 --> 00:09:05,085
is gathering information
collected all over the world

177
00:09:05,210 --> 00:09:06,543
by science vessels,

178
00:09:06,710 --> 00:09:10,043
merchant ships,
and underwater drones.

179
00:09:10,168 --> 00:09:14,751
Their goal is to map
the entire ocean floor

180
00:09:14,918 --> 00:09:19,376
by the year 2030,
a feat that seemed impossible

181
00:09:19,460 --> 00:09:21,876
for most of human history.

182
00:09:22,001 --> 00:09:23,710
Technology is always the key.

183
00:09:23,793 --> 00:09:25,460
Technology allows us

184
00:09:25,585 --> 00:09:27,085
to do things that we
couldn't do before

185
00:09:27,210 --> 00:09:30,001
and see those things that
no one has ever seen before.

186
00:09:30,126 --> 00:09:31,043
It's human progress

187
00:09:31,210 --> 00:09:34,043
and really pushing ourselves
to the next level.

188
00:09:35,751 --> 00:09:38,793
It's really quite extraordinary
that we have the ability

189
00:09:38,918 --> 00:09:41,335
to journey to the very
bottom of the ocean,

190
00:09:41,418 --> 00:09:43,793
and scientists are making

191
00:09:43,918 --> 00:09:47,710
incredible underwater
discoveries all the time.

192
00:09:47,876 --> 00:09:50,710
For instance, a new landmass
was recently found

193
00:09:50,835 --> 00:09:52,626
off the coast of New Zealand.

194
00:09:52,751 --> 00:09:55,626
And there are those
who believe that it could be

195
00:09:55,751 --> 00:09:58,251
part of a lost continent.

196
00:10:06,085 --> 00:10:09,460
A team of
geologists at GNS Science

197
00:10:09,585 --> 00:10:11,376
announce a major discovery

198
00:10:11,543 --> 00:10:13,376
related to the Earth's
continents,

199
00:10:13,460 --> 00:10:17,543
the vast landmasses that
make up the planet's surface.

200
00:10:17,626 --> 00:10:19,543
The scientists found that,

201
00:10:19,668 --> 00:10:21,585
in addition to
the seven continents

202
00:10:21,751 --> 00:10:23,835
that humans have
known about for centuries,

203
00:10:23,960 --> 00:10:26,585
there's also
an eighth continent

204
00:10:26,710 --> 00:10:29,210
located directly
underneath New Zealand,

205
00:10:29,376 --> 00:10:31,460
which they named Zealandia.

206
00:10:31,585 --> 00:10:34,543
Zealandia sank into the ocean

207
00:10:34,626 --> 00:10:37,168
approximately
50 million years ago,

208
00:10:37,251 --> 00:10:39,043
and its existence suggests

209
00:10:39,126 --> 00:10:42,043
that there may be even
more lost continents

210
00:10:42,126 --> 00:10:44,793
that were swallowed up
by the sea.

211
00:10:47,251 --> 00:10:50,543
The Earth has cycles of sea
level rise and sea level fall.

212
00:10:50,668 --> 00:10:53,710
Over the last hundreds
of millions of years,

213
00:10:53,793 --> 00:10:56,543
as climate has warmed
we get sea level rise;

214
00:10:56,626 --> 00:10:59,543
cold periods, sea level fall.

215
00:10:59,626 --> 00:11:02,876
There's a huge amount
of land which is now

216
00:11:02,960 --> 00:11:04,876
covered by the sea.

217
00:11:05,001 --> 00:11:06,543
10,000 years ago,

218
00:11:06,668 --> 00:11:08,085
with the end of the Ice Age,

219
00:11:08,251 --> 00:11:11,335
sea levels were dramatically
lower than they are now.

220
00:11:12,751 --> 00:11:14,085
And because of the melting

221
00:11:14,210 --> 00:11:17,210
of the ice, sea levels
have risen since then,

222
00:11:17,293 --> 00:11:21,585
and cities that may have existed
thousands of years ago

223
00:11:21,710 --> 00:11:25,085
could be lost in history
as a consequence.

224
00:11:27,793 --> 00:11:30,210
For thousands of years,
cultures from around the world

225
00:11:30,335 --> 00:11:33,126
have told stories about
long-lost continents

226
00:11:33,251 --> 00:11:36,001
that were home
to human civilizations

227
00:11:36,126 --> 00:11:38,960
and are now submerged
beneath the waves.

228
00:11:40,210 --> 00:11:43,918
Perhaps the most famous
is the legend of Atlantis,

229
00:11:44,085 --> 00:11:47,418
a massive island that was home
to an advanced civilization

230
00:11:47,543 --> 00:11:52,376
before it supposedly sank into
the ocean after an earthquake.

231
00:11:52,501 --> 00:11:55,543
There's been more books
written about Atlantis

232
00:11:55,626 --> 00:11:58,251
than any other
lost continent in history.

233
00:11:58,376 --> 00:11:59,210
There are many

234
00:11:59,335 --> 00:12:01,710
sunken cities, lost lands,

235
00:12:01,793 --> 00:12:03,960
destroyed continents
all around the planet

236
00:12:04,085 --> 00:12:05,293
in legend and history.

237
00:12:05,418 --> 00:12:09,585
For example, we have
the lost land of Hy-Brasil,

238
00:12:09,751 --> 00:12:10,751
which was thought to be

239
00:12:10,876 --> 00:12:14,626
200 miles off the coast
of Ireland,

240
00:12:14,751 --> 00:12:17,210
and it was even on maps
until the 1800s.

241
00:12:18,543 --> 00:12:21,585
One of the most intriguing
lost continents is a landmass

242
00:12:21,710 --> 00:12:24,876
that is believed to have once
existed in the Pacific Ocean.

243
00:12:25,001 --> 00:12:29,876
A mythical land
that is known as Mu.

244
00:12:31,001 --> 00:12:33,376
The first person
to write extensively

245
00:12:33,543 --> 00:12:35,585
about the lost continent of Mu

246
00:12:35,710 --> 00:12:38,751
was a Scottish writer

247
00:12:38,918 --> 00:12:41,460
by the name of James Churchward.

248
00:12:41,585 --> 00:12:47,168
In the 19th century,
he was in India when he visited

249
00:12:47,251 --> 00:12:48,876
a monastery.

250
00:12:49,001 --> 00:12:53,210
And the monks there had records,
apparently, tablets

251
00:12:53,335 --> 00:12:57,168
that referred to
this place called Mu

252
00:12:57,293 --> 00:13:02,335
that was this huge continent
that supposedly existed

253
00:13:02,418 --> 00:13:04,710
from Hawaii in the north

254
00:13:04,876 --> 00:13:08,085
down to Easter Island
in the southeast,

255
00:13:08,210 --> 00:13:12,418
right the way across
to Micronesia in the west.

256
00:13:12,543 --> 00:13:16,543
And the people there were
supposedly called the Naacal.

257
00:13:17,918 --> 00:13:22,210
The continent of Mu thrived
perhaps 50,000 years ago

258
00:13:22,335 --> 00:13:25,918
and was sunk beneath the waves,

259
00:13:26,043 --> 00:13:29,001
possibly at the end
of the last Ice Age.

260
00:13:31,085 --> 00:13:32,918
My great-grandfather
James Churchward,

261
00:13:33,085 --> 00:13:36,585
eventually he became friends
with the rishi of the temple

262
00:13:36,710 --> 00:13:38,710
that he visited in India.

263
00:13:38,835 --> 00:13:41,043
And the rishi mentioned
that he was a member

264
00:13:41,126 --> 00:13:42,876
of the Naacal brotherhood,

265
00:13:42,960 --> 00:13:45,460
the holders of wisdom
and knowledge

266
00:13:45,585 --> 00:13:47,960
of the lost continent of Mu.

267
00:13:49,001 --> 00:13:51,210
They were mighty
navigators and sailors

268
00:13:51,293 --> 00:13:55,251
and established civilization
in other parts of the world.

269
00:13:56,918 --> 00:13:58,210
According
to James Churchward,

270
00:13:58,293 --> 00:14:00,210
the Naacal civilization
had a population

271
00:14:00,335 --> 00:14:03,210
of more than 60 million
people at its peak

272
00:14:03,335 --> 00:14:07,918
before a massive volcanic
cataclysm caused Mu to vanish

273
00:14:08,043 --> 00:14:10,001
beneath the waters.

274
00:14:11,251 --> 00:14:13,876
So far, no evidence
of the lost continent

275
00:14:13,960 --> 00:14:16,126
has been found
on the ocean floor.

276
00:14:17,251 --> 00:14:19,626
But some researchers
claim that, incredibly,

277
00:14:19,751 --> 00:14:24,043
a tiny remnant of Mu may still
exist above water today

278
00:14:24,168 --> 00:14:29,251
on an island located in a remote
part of the Pacific Ocean.

279
00:14:31,460 --> 00:14:34,210
Roughly 2,500 miles
northeast of Australia

280
00:14:34,376 --> 00:14:37,418
lie the ruins of a once
great ancient city.

281
00:14:37,585 --> 00:14:38,960
Nan Madol.

282
00:14:39,960 --> 00:14:43,043
Nan Madol is a complex
of man-made islands

283
00:14:43,126 --> 00:14:47,043
built with massive stone
blocks that float atop

284
00:14:47,126 --> 00:14:49,460
a submerged coral reef.

285
00:14:49,585 --> 00:14:51,751
So as you approach Nan Madol,

286
00:14:51,918 --> 00:14:55,210
there are a series of islands,

287
00:14:55,376 --> 00:14:57,168
and they're built
actually on coral,

288
00:14:57,293 --> 00:15:00,418
the only place in the world
where this actually occurs.

289
00:15:02,126 --> 00:15:04,710
And you've got all these
incredible structures

290
00:15:04,835 --> 00:15:07,293
made of these prismatic blocks.

291
00:15:09,293 --> 00:15:10,876
At Nan Madol, you have these

292
00:15:10,960 --> 00:15:13,710
ridiculous basalt columns,
they're huge,

293
00:15:13,835 --> 00:15:15,126
some of them up to,
like, 40 tons,

294
00:15:15,251 --> 00:15:16,543
even more in some cases.

295
00:15:16,710 --> 00:15:19,501
Some of them are raised
very high up in the air,

296
00:15:19,585 --> 00:15:21,085
on the very top levels.

297
00:15:21,210 --> 00:15:23,418
So there's a real problem when
it comes to try and understand

298
00:15:23,543 --> 00:15:27,376
how they moved these millions
of tons of basalt columns.

299
00:15:28,585 --> 00:15:30,460
One of the biggest mysteries

300
00:15:30,585 --> 00:15:32,376
surrounding Nan Madol

301
00:15:32,501 --> 00:15:36,793
is that nobody really knows
who constructed it.

302
00:15:36,918 --> 00:15:38,876
But there's some
very strange stories

303
00:15:39,001 --> 00:15:43,085
about how the city
came into existence.

304
00:15:44,126 --> 00:15:47,126
For instance,
one of the stories talks about

305
00:15:47,251 --> 00:15:50,335
it being constructed
by so-called master builders...

306
00:15:51,585 --> 00:15:55,710
...turning up
and using a magical force...

307
00:15:56,918 --> 00:16:01,626
...to raise the blocks into
the air and put them into place,

308
00:16:01,751 --> 00:16:05,251
almost as if they could
levitate these blocks.

309
00:16:08,085 --> 00:16:09,585
Some people actually suggested

310
00:16:09,751 --> 00:16:14,043
that maybe Nan Madol
was the last remnant of Mu

311
00:16:14,168 --> 00:16:15,626
that was still above water...

312
00:16:17,001 --> 00:16:18,210
...and it was simply

313
00:16:18,376 --> 00:16:21,376
indicative of what had sunk

314
00:16:21,460 --> 00:16:25,710
beneath the waves from
this advanced civilization.

315
00:16:25,793 --> 00:16:28,251
Nan Madol is in Micronesia,

316
00:16:28,376 --> 00:16:31,126
so it fit the correct
general area.

317
00:16:31,251 --> 00:16:34,668
And this is one reason people
thought in terms of Mu.

318
00:16:35,960 --> 00:16:38,960
When it comes to looking
for this lost continent of Mu,

319
00:16:39,085 --> 00:16:42,126
places like Nan Madol
really do suggest

320
00:16:42,251 --> 00:16:44,626
there could be much more
down there than we realize

321
00:16:44,751 --> 00:16:46,418
on the bottom of the ocean.

322
00:16:47,460 --> 00:16:50,543
It's hard to picture
an entire continent,

323
00:16:50,626 --> 00:16:55,251
with people living on it,
simply vanishing into the sea.

324
00:16:55,376 --> 00:16:56,418
And yet...

325
00:16:57,501 --> 00:17:00,293
...all over the world,
there are legends of lost

326
00:17:00,418 --> 00:17:04,501
civilizations that were
swallowed up by the oceans.

327
00:17:04,626 --> 00:17:09,168
But could such legends
actually be true?

328
00:17:10,251 --> 00:17:12,376
Perhaps the answer
can be found by examining

329
00:17:12,460 --> 00:17:17,251
a mysterious structure
located in the Pacific Ocean

330
00:17:17,376 --> 00:17:19,043
that has come to be known as

331
00:17:19,168 --> 00:17:26,043
Japan's Atlantis.

332
00:17:26,126 --> 00:17:27,876
At the western end
of the Pacific Ocean,

333
00:17:27,960 --> 00:17:30,126
67 miles off the coast
of Taiwan,

334
00:17:30,251 --> 00:17:34,126
is the Japanese island
of Yonaguni.

335
00:17:34,251 --> 00:17:38,210
It is one of some
6,800 landforms

336
00:17:38,335 --> 00:17:40,043
in the Japanese archipelago,

337
00:17:40,168 --> 00:17:41,460
a chain of small islands

338
00:17:41,585 --> 00:17:44,210
located near the southern
tip of Japan.

339
00:17:45,335 --> 00:17:47,251
But just off the coast
of Yonaguni lies

340
00:17:47,376 --> 00:17:50,918
a mysterious complex
of underwater stone formations

341
00:17:51,085 --> 00:17:54,751
known as the Yonaguni Monument.

342
00:17:55,960 --> 00:17:58,543
It's an absolutely
incredible structure,

343
00:17:58,626 --> 00:18:01,876
and it looks like
a giant staircase.

344
00:18:02,001 --> 00:18:06,460
Steps in the bedrock
with terraces.

345
00:18:06,585 --> 00:18:10,418
The symmetry and the regularity
that people see on it

346
00:18:10,543 --> 00:18:12,626
just makes
a astounding impression.

347
00:18:14,210 --> 00:18:18,960
It looks like a huge,
multifaceted pyramid platform

348
00:18:19,085 --> 00:18:21,168
that stretches over a huge area

349
00:18:21,251 --> 00:18:23,585
with all these details
carved into it.

350
00:18:23,751 --> 00:18:27,293
There's areas where monoliths
were said to have been standing.

351
00:18:27,418 --> 00:18:31,210
There's even dolmens
or large slabs like lintels

352
00:18:31,335 --> 00:18:35,668
covering areas and creating
doorways and other features.

353
00:18:37,376 --> 00:18:39,168
When you look at some
of the rock structures,

354
00:18:39,293 --> 00:18:41,126
it looks undeniably man-made.

355
00:18:41,251 --> 00:18:43,085
But with that comes
a whole series of questions.

356
00:18:43,251 --> 00:18:45,335
How did it get here?
How long has it been here?

357
00:18:45,460 --> 00:18:47,126
What is the structure
you're looking at?

358
00:18:48,751 --> 00:18:52,376
The Yonaguni Monument was
discovered by divers in 1987,

359
00:18:52,460 --> 00:18:53,960
and since that time,

360
00:18:54,085 --> 00:18:57,376
experts have debated whether
it's a natural formation

361
00:18:57,460 --> 00:19:01,168
caused by erosion
or an artificial structure

362
00:19:01,251 --> 00:19:04,335
that was carved by man
in the distant past.

363
00:19:05,585 --> 00:19:08,335
Researchers who believe
that the monument is man-made

364
00:19:08,418 --> 00:19:09,918
claim that it is the ruins

365
00:19:10,085 --> 00:19:12,460
of a massive stepped
pyramid complex

366
00:19:12,585 --> 00:19:17,293
that is nearly 500 feet long,
130 feet wide, and 90 feet tall.

367
00:19:18,460 --> 00:19:22,210
The Yonaguni Monument
was originally above water,

368
00:19:22,335 --> 00:19:25,376
but at some point in the past,

369
00:19:25,501 --> 00:19:28,043
waters rose up and covered it

370
00:19:28,126 --> 00:19:32,460
and it's now beneath
almost 100 feet of water.

371
00:19:32,585 --> 00:19:36,001
You have not only these
geometrical structures,

372
00:19:36,126 --> 00:19:37,043
these terraces,

373
00:19:37,210 --> 00:19:39,668
but also some strange monuments,

374
00:19:39,793 --> 00:19:43,293
including what appears to be
this human head.

375
00:19:43,418 --> 00:19:45,668
It's 23 feet tall

376
00:19:45,793 --> 00:19:49,418
and it has these
hollow sunken eyes.

377
00:19:49,543 --> 00:19:54,043
It almost looks like the moai
statues of Easter Island.

378
00:19:54,168 --> 00:19:56,001
It looks hauntingly like

379
00:19:56,085 --> 00:19:58,210
some kind of giant of the past.

380
00:19:59,751 --> 00:20:03,001
Underwater archaeologists
who have visited Yonaguni

381
00:20:03,126 --> 00:20:05,085
have also noted that
there appears to be

382
00:20:05,210 --> 00:20:07,835
a sculpture of a sea turtle.

383
00:20:07,918 --> 00:20:11,835
And some even claim
there is a carved roadway

384
00:20:11,918 --> 00:20:14,001
circling the entire site.

385
00:20:16,751 --> 00:20:18,543
There's so many elements to it

386
00:20:18,626 --> 00:20:22,626
which suggest it's at least
been manipulated by man,

387
00:20:22,751 --> 00:20:25,126
because it looks like it's been
carved from solid rock.

388
00:20:25,251 --> 00:20:27,710
And one of the theories
that has kind of caught

389
00:20:27,835 --> 00:20:30,710
many researchers' attention
is that it could be evidence

390
00:20:30,876 --> 00:20:34,710
of a lost civilization
many thousands of years old.

391
00:20:34,835 --> 00:20:37,835
Some people have
thought of Yonaguni

392
00:20:37,960 --> 00:20:41,793
being "Japan's Atlantis,"

393
00:20:41,918 --> 00:20:46,126
in the sense that if
Yonaguni is an artificial,

394
00:20:46,251 --> 00:20:49,626
human construction
from very ancient times,

395
00:20:49,751 --> 00:20:54,043
it must represent the tip
of the proverbial iceberg

396
00:20:54,126 --> 00:20:55,876
of an advanced civilization

397
00:20:55,960 --> 00:20:59,210
thousands of years ago
that somehow disappeared

398
00:20:59,335 --> 00:21:02,376
into the ocean under the waves.

399
00:21:04,001 --> 00:21:05,543
Is the Yonaguni Monument

400
00:21:05,626 --> 00:21:07,376
the remains
of a lost civilization?

401
00:21:07,501 --> 00:21:12,293
And if so, how long ago
did that civilization exist?

402
00:21:13,501 --> 00:21:16,210
One of the really,
really interesting,

403
00:21:16,335 --> 00:21:18,918
mystifying things
about the Yonaguni Monument

404
00:21:19,043 --> 00:21:20,710
is the depth of water.

405
00:21:20,876 --> 00:21:22,293
So, it's 25 meters.

406
00:21:23,501 --> 00:21:28,376
Now, if we were relying
on the pulses of sea level rise

407
00:21:28,460 --> 00:21:30,085
from kind of the end
of the Ice Age

408
00:21:30,210 --> 00:21:33,293
10,000 years ago, that means
that the Yonaguni Monument

409
00:21:33,418 --> 00:21:37,210
would be 12,000
to 14,000 years old.

410
00:21:37,293 --> 00:21:38,960
That's going to predate

411
00:21:39,085 --> 00:21:42,418
the earliest civilizations
we know of by 7,000 years or so.

412
00:21:43,668 --> 00:21:47,001
If the Yonaguni Monument was
man-made, then it is a truly

413
00:21:47,085 --> 00:21:48,585
seismic discovery in terms

414
00:21:48,710 --> 00:21:50,876
of the history of
our species because,

415
00:21:50,960 --> 00:21:55,585
potentially, the cradle of human
civilization was Japan,

416
00:21:55,710 --> 00:21:57,126
was off the coast of Japan.

417
00:21:57,251 --> 00:22:01,043
Is it possible that
the Yonaguni Monument

418
00:22:01,210 --> 00:22:02,376
is not only man-made

419
00:22:02,543 --> 00:22:05,543
but also much older
than any other ruin

420
00:22:05,668 --> 00:22:07,335
that's ever been discovered?

421
00:22:07,460 --> 00:22:09,418
Many scientists believe

422
00:22:09,585 --> 00:22:12,210
that further research
on this remarkable structure

423
00:22:12,335 --> 00:22:14,085
could rewrite history

424
00:22:14,251 --> 00:22:18,543
and offer tangible evidence
in support of the theory

425
00:22:18,668 --> 00:22:21,501
that there are remnants of lost

426
00:22:21,585 --> 00:22:25,335
civilizations hidden
in the world's oceans.

427
00:22:26,793 --> 00:22:29,126
Are there some
foundational cities

428
00:22:29,251 --> 00:22:31,043
underneath the water?

429
00:22:31,126 --> 00:22:32,501
I wouldn't bet against it.

430
00:22:32,626 --> 00:22:35,210
If we want to unlock the secrets
of ancient civilizations,

431
00:22:35,335 --> 00:22:38,460
we may very well
have to look underwater.

432
00:22:39,460 --> 00:22:41,418
What we are beginning to learn

433
00:22:41,543 --> 00:22:44,460
is the huge potential of

434
00:22:44,585 --> 00:22:47,876
mysteries in the sea, as in
what the sea can give us

435
00:22:47,960 --> 00:22:53,085
in terms of new discoveries,
new glimpses into other worlds.

436
00:22:53,210 --> 00:22:56,626
And the Yonaguni Monument
is a real manifestation of that.

437
00:22:57,501 --> 00:22:59,335
The mere possibility

438
00:22:59,418 --> 00:23:01,335
that the ruins of
an ancient civilization

439
00:23:01,418 --> 00:23:03,210
could be lying on the floor
of the Pacific Ocean

440
00:23:03,335 --> 00:23:04,835
is fascinating.

441
00:23:04,918 --> 00:23:09,335
But our next underwater mystery
can be found not in the ocean

442
00:23:09,418 --> 00:23:11,585
but at the bottom
of a vast lake.

443
00:23:11,710 --> 00:23:16,001
A lake that holds gold and
silver artifacts that date back

444
00:23:16,126 --> 00:23:25,501
thousands of years.

445
00:23:25,585 --> 00:23:29,210
High atop this
5,500-mile-long mountain range

446
00:23:29,335 --> 00:23:32,210
lies Lake Titicaca,

447
00:23:32,335 --> 00:23:36,751
one of the most picturesque
bodies of water in the world.

448
00:23:36,918 --> 00:23:39,710
Lake Titicaca sits
at a remarkable elevation

449
00:23:39,835 --> 00:23:44,543
of 12,500 feet, which is roughly
two miles above sea level.

450
00:23:47,418 --> 00:23:49,668
Lake Titicaca is a massive lake

451
00:23:49,751 --> 00:23:52,043
in the midst
of a mountain range,

452
00:23:52,126 --> 00:23:56,210
and it's about 120 miles long

453
00:23:56,293 --> 00:23:58,710
and 30-some miles wide.

454
00:23:59,751 --> 00:24:02,626
It extends down
nearly a thousand feet,

455
00:24:02,751 --> 00:24:06,585
and it's the highest
navigable lake in the world.

456
00:24:06,710 --> 00:24:08,668
It's quite unusual
to be on something

457
00:24:08,751 --> 00:24:11,043
that looks like a sea
when you're on it

458
00:24:11,126 --> 00:24:14,960
and see snowcapped peaks...
surrounding it.

459
00:24:15,085 --> 00:24:17,085
You might think
that a lake located

460
00:24:17,210 --> 00:24:20,876
at such a high and remote
location would have no traces

461
00:24:21,043 --> 00:24:22,126
of human activity.

462
00:24:22,251 --> 00:24:23,876
But what's incredible

463
00:24:23,960 --> 00:24:27,210
about Lake Titicaca
is that, for decades,

464
00:24:27,293 --> 00:24:29,210
archaeologists have been finding

465
00:24:29,335 --> 00:24:32,876
mysterious gold
artifacts submerged

466
00:24:33,043 --> 00:24:35,001
within its icy waters.

467
00:24:38,001 --> 00:24:40,960
Excavations
of Lake Titicaca found

468
00:24:41,085 --> 00:24:44,126
2,000 artifacts of gold,
silver, and pottery.

469
00:24:45,418 --> 00:24:48,418
Normally, of course on land you
would find that, but to find it

470
00:24:48,543 --> 00:24:52,001
in the lake was very
mysterious and surprising.

471
00:24:54,085 --> 00:24:57,210
There's more than
40-some carved stone boxes

472
00:24:57,335 --> 00:24:58,543
that have been found.

473
00:24:58,668 --> 00:25:04,085
Many of them have little
grooves in their sides,

474
00:25:04,210 --> 00:25:06,418
which was where the ropes were

475
00:25:06,543 --> 00:25:09,376
tied around them
so they wouldn't slip out

476
00:25:09,501 --> 00:25:11,626
when they were being
lowered into the water.

477
00:25:12,835 --> 00:25:15,918
Now, the exciting thing
about finding these boxes

478
00:25:16,043 --> 00:25:19,585
with a lid is the kinds of finds
that were being made in them,

479
00:25:19,710 --> 00:25:22,376
such as a gold vase,

480
00:25:22,501 --> 00:25:24,835
a gold medallion,

481
00:25:24,918 --> 00:25:28,043
and gold feline figurines.

482
00:25:29,460 --> 00:25:32,168
But why would the ancient
peoples of this region make

483
00:25:32,293 --> 00:25:35,626
a difficult trek to this lake
that is located atop

484
00:25:35,751 --> 00:25:38,543
one of the least accessible
mountain ranges in the world

485
00:25:38,668 --> 00:25:42,460
to leave so many gold artifacts

486
00:25:42,585 --> 00:25:44,543
at the bottom of the lake?

487
00:25:46,043 --> 00:25:49,751
This entire area of the Andes
is associated with the Inca.

488
00:25:51,126 --> 00:25:54,001
And they are responsible
for many of the finds

489
00:25:54,085 --> 00:25:56,293
that have been made
in Lake Titicaca.

490
00:25:57,543 --> 00:26:00,210
The Inca were
a South American civilization

491
00:26:00,335 --> 00:26:03,710
that controlled 2,500 miles

492
00:26:03,835 --> 00:26:07,335
stretching all the way
from Peru, modern-day Bolivia,

493
00:26:07,460 --> 00:26:10,585
Guatemala into Chile
and Argentina.

494
00:26:11,835 --> 00:26:13,751
Lake Titicaca was one
of the most sacred places

495
00:26:13,918 --> 00:26:16,376
in the entire Inca Empire.

496
00:26:16,501 --> 00:26:18,543
It was sacred because it was

497
00:26:18,710 --> 00:26:23,043
one of the most important
freshwater bodies of water

498
00:26:23,168 --> 00:26:24,835
in all of South America.

499
00:26:26,918 --> 00:26:30,210
When the Inca realized
the incredible value

500
00:26:30,293 --> 00:26:31,960
of the Lake Titicaca basin...

501
00:26:33,168 --> 00:26:37,335
...they initiated a program
of religious pilgrimages,

502
00:26:37,418 --> 00:26:39,960
essentially, saying that

503
00:26:40,085 --> 00:26:43,793
their key creator god,
known as Viracocha,

504
00:26:43,918 --> 00:26:46,376
rose up out of the waters
of Lake Titicaca

505
00:26:46,460 --> 00:26:48,751
to create all humanity.

506
00:26:50,543 --> 00:26:51,835
Lake Titicaca

507
00:26:51,918 --> 00:26:54,543
is the mythological origin

508
00:26:54,626 --> 00:26:56,876
of the entire Inca Empire.

509
00:26:56,960 --> 00:27:00,626
They believed that they were
descendants of the cultures

510
00:27:00,751 --> 00:27:03,168
that had evolved
at Lake Titicaca.

511
00:27:04,126 --> 00:27:06,043
There were legends
of temples and whatnot

512
00:27:06,126 --> 00:27:09,210
underwater in Lake Titicaca,
long before the Incas.

513
00:27:10,918 --> 00:27:12,751
According to Inca legend,

514
00:27:12,918 --> 00:27:15,793
a civilization that existed
centuries prior to them

515
00:27:15,918 --> 00:27:18,293
rose from the waters
of Lake Titicaca.

516
00:27:18,418 --> 00:27:21,710
Remarkably, archaeologists
have uncovered evidence

517
00:27:21,793 --> 00:27:25,876
which suggests that there
may be some truth to this myth.

518
00:27:27,960 --> 00:27:31,376
In August of 2000,
an Italian team of divers

519
00:27:31,501 --> 00:27:34,001
uncovered traces
of a paved road,

520
00:27:34,085 --> 00:27:36,085
a stone terrace,

521
00:27:36,251 --> 00:27:39,460
and a wall nearly
a half a mile long.

522
00:27:39,585 --> 00:27:42,835
They found themselves swimming
along what looked to be

523
00:27:42,918 --> 00:27:45,210
an ancient paved roadway.

524
00:27:45,335 --> 00:27:47,376
And they passed what looked
like it could have been

525
00:27:47,543 --> 00:27:49,126
terraced agricultural fields

526
00:27:49,251 --> 00:27:52,501
quite similar
to what you can see

527
00:27:52,626 --> 00:27:55,335
around the shores
of the lake even today.

528
00:27:55,460 --> 00:27:58,418
But what they found
at the end of this road

529
00:27:58,585 --> 00:28:00,251
really astonished them.

530
00:28:00,376 --> 00:28:03,793
It was a giant temple complex,

531
00:28:03,918 --> 00:28:07,335
the size of two football fields.

532
00:28:07,418 --> 00:28:09,793
Archaeologists were able
to see that these were

533
00:28:09,918 --> 00:28:14,835
extremely ancient,
1,000 to 1,500 years old.

534
00:28:16,668 --> 00:28:17,918
We found artifacts

535
00:28:18,043 --> 00:28:22,210
dating from around 300, 400 AD,
until about 1100 AD.

536
00:28:22,376 --> 00:28:25,293
And then you have the Inca
coming in around 1400 AD.

537
00:28:25,418 --> 00:28:27,710
So that means that Lake Titicaca

538
00:28:27,793 --> 00:28:30,126
was a sacred place
to civilizations

539
00:28:30,251 --> 00:28:33,293
that dominated the Andes
before the Incas.

540
00:28:35,710 --> 00:28:38,501
The ruins found at the bottom
of Lake Titicaca would seem

541
00:28:38,585 --> 00:28:41,751
to validate the Inca belief
that there was another culture

542
00:28:41,876 --> 00:28:44,043
present there long before them.

543
00:28:44,168 --> 00:28:48,126
But how did these ruins
become submerged?

544
00:28:49,376 --> 00:28:51,793
We've got these
structures underwater.

545
00:28:51,918 --> 00:28:54,876
They're 1,500 years old
or older.

546
00:28:54,960 --> 00:28:57,085
It's one thing to find
artifacts underwater

547
00:28:57,251 --> 00:28:59,210
and they may have been
dropped or may have been

548
00:28:59,376 --> 00:29:03,126
purposefully, um, sacrificed
to the lake, if you would.

549
00:29:04,418 --> 00:29:08,043
But when you find temples and
walls and roadways underwater,

550
00:29:08,168 --> 00:29:10,668
you know that
something was going on

551
00:29:10,751 --> 00:29:12,793
at a much earlier period.

552
00:29:12,918 --> 00:29:16,168
Certainly they were not building
these things underwater.

553
00:29:16,293 --> 00:29:20,751
We do know that Lake Titicaca
fluctuates in terms of

554
00:29:20,876 --> 00:29:24,876
the water levels over time
over thousands of years.

555
00:29:25,001 --> 00:29:29,043
So this is incredibly
important and fascinating

556
00:29:29,126 --> 00:29:31,793
and it ties in with Inca beliefs

557
00:29:31,918 --> 00:29:33,876
that they thought
this was a place

558
00:29:33,960 --> 00:29:36,043
that was literally
the birthplace

559
00:29:36,168 --> 00:29:39,793
of civilization for them,
up in the high Andes.

560
00:29:42,501 --> 00:29:45,001
The enduring mysteries
associated

561
00:29:45,085 --> 00:29:49,668
with Lake Titicaca would be,
for example, who was the first

562
00:29:49,793 --> 00:29:51,293
civilization to live here?

563
00:29:51,418 --> 00:29:56,043
We have no idea how far
back in time humanity goes

564
00:29:56,168 --> 00:30:00,460
in terms of the first habitation
or inhabitation of this lake.

565
00:30:00,585 --> 00:30:04,751
But that's why there should
be more underwater archaeology

566
00:30:04,876 --> 00:30:06,543
done here in Lake Titicaca,

567
00:30:06,668 --> 00:30:11,710
in order to be able to fully
comprehend the true history

568
00:30:11,793 --> 00:30:14,960
of this amazing aquatic area.

569
00:30:17,168 --> 00:30:20,710
What else might be submerged
at the bottom of Lake Titicaca?

570
00:30:20,793 --> 00:30:22,335
Could there be other artifacts

571
00:30:22,418 --> 00:30:24,835
that might change our
understanding of human history?

572
00:30:24,918 --> 00:30:28,293
Well, the diving
expeditions continue,

573
00:30:28,418 --> 00:30:30,210
as do the revelations.

574
00:30:30,335 --> 00:30:35,876
But let's consider a different
kind of undersea discovery.

575
00:30:36,043 --> 00:30:38,293
One that makes us
question not our past

576
00:30:38,418 --> 00:30:48,251
but rather whether
we're alone in the universe.

577
00:30:48,376 --> 00:30:51,543
100 miles
off the coast of San Diego,

578
00:30:51,668 --> 00:30:53,710
a group of U.S. warships
are conducting

579
00:30:53,835 --> 00:30:55,960
routine training exercises

580
00:30:56,085 --> 00:30:58,876
when they detect
a number of unidentified

581
00:30:58,960 --> 00:31:02,210
flying objects
near Catalina Island.

582
00:31:02,376 --> 00:31:05,668
They were picking up multiple
targets on the radar system,

583
00:31:05,793 --> 00:31:07,751
but they had a new
system they were testing.

584
00:31:07,876 --> 00:31:10,543
So the theory was
that it was just glitches,

585
00:31:10,710 --> 00:31:12,418
and so they rebooted.

586
00:31:12,585 --> 00:31:16,001
But sure enough,
these targets showed up again.

587
00:31:16,085 --> 00:31:18,835
And this goes on
for a series of some days,

588
00:31:18,960 --> 00:31:22,543
and then they vectored jets
to go and investigate.

589
00:31:23,835 --> 00:31:26,751
As Navy F-18 fighter jets
approach the area where the UFOs

590
00:31:26,876 --> 00:31:28,376
had been detected on radar,

591
00:31:28,460 --> 00:31:32,001
the pilots see a white,
oval-shaped object

592
00:31:32,126 --> 00:31:33,876
that has no wings

593
00:31:34,001 --> 00:31:37,418
and resembles a giant Tic Tac.

594
00:31:38,751 --> 00:31:40,168
But then suddenly,

595
00:31:40,251 --> 00:31:43,168
it rapidly descends 80,000 feet
in less than a second

596
00:31:43,251 --> 00:31:47,168
and hovers above
the surface of the water.

597
00:31:48,168 --> 00:31:50,501
Naval Officer Ryan Weigelt

598
00:31:50,585 --> 00:31:53,585
was stationed
on the nearby USS Princeton

599
00:31:53,710 --> 00:31:56,293
on the day of the encounter.

600
00:31:56,418 --> 00:31:59,210
I was called
to the bridge by the CO

601
00:31:59,293 --> 00:32:00,710
and when I got up to the bridge,

602
00:32:00,835 --> 00:32:05,626
the whole office was much more
crowded and chaotic than normal.

603
00:32:05,751 --> 00:32:07,876
People were raising their voice

604
00:32:08,043 --> 00:32:10,001
on seeing some of the things
that they were seeing.

605
00:32:10,126 --> 00:32:12,043
It was
a very excited atmosphere.

606
00:32:12,168 --> 00:32:15,210
I noticed that
to my left-hand side

607
00:32:15,293 --> 00:32:18,043
was a video monitor
where the FLIR footage

608
00:32:18,168 --> 00:32:19,960
was being fed
into the Princeton,

609
00:32:20,085 --> 00:32:21,626
so I could see
what the jets were seeing.

610
00:32:21,751 --> 00:32:23,710
On my right-hand side

611
00:32:23,835 --> 00:32:25,876
I am watching them
on a radar screen

612
00:32:25,960 --> 00:32:27,751
that gives information
on altitude

613
00:32:27,876 --> 00:32:29,543
and speed and heading and...

614
00:32:29,668 --> 00:32:31,710
Seeing what I saw,

615
00:32:31,793 --> 00:32:35,335
it's impossible for anything
that we own or have created

616
00:32:35,418 --> 00:32:38,793
to withstand the G forces
that would be created

617
00:32:38,918 --> 00:32:41,126
from doing any type of thrusts,

618
00:32:41,251 --> 00:32:43,501
like what this Tic Tac
was doing.

619
00:32:44,751 --> 00:32:47,626
Two of the pilots involved
in the Tic Tac incident,

620
00:32:47,751 --> 00:32:49,376
Commander David Fravor

621
00:32:49,460 --> 00:32:52,001
and Lieutenant Commander
Alex Dietrich,

622
00:32:52,085 --> 00:32:56,168
have stated that under
the infamous Tic Tac,

623
00:32:56,251 --> 00:32:59,876
there was an area of water
that was roiling,

624
00:32:59,960 --> 00:33:03,668
as if there was this
object under the waves.

625
00:33:03,751 --> 00:33:05,668
And this object was about

626
00:33:05,751 --> 00:33:08,376
the size of a Boeing 737.

627
00:33:09,835 --> 00:33:11,043
Navy eyewitnesses

628
00:33:11,210 --> 00:33:13,168
have reported that
the Tic Tac was moving

629
00:33:13,293 --> 00:33:15,501
erratically above
the surface of the water,

630
00:33:15,585 --> 00:33:18,376
as though it appeared
to be interacting

631
00:33:18,501 --> 00:33:21,793
with the unidentified object
located beneath the waves.

632
00:33:21,918 --> 00:33:24,043
Moments later, the Tic Tac

633
00:33:24,126 --> 00:33:26,835
made a series of seemingly
impossible maneuvers

634
00:33:26,960 --> 00:33:30,126
to evade the Navy jets
before accelerating away

635
00:33:30,251 --> 00:33:32,835
at thousands of miles per hour.

636
00:33:32,960 --> 00:33:36,460
And the pilots claim that when
they tried to get a second look

637
00:33:36,585 --> 00:33:41,876
at the underwater object,
it had somehow vanished.

638
00:33:42,001 --> 00:33:44,876
I am a person who needs to see

639
00:33:45,001 --> 00:33:47,543
to really believe and...

640
00:33:47,668 --> 00:33:52,251
seeing what I saw
during that time frame,

641
00:33:52,376 --> 00:33:57,043
I think any rational-minded
person would be somewhat alarmed

642
00:33:57,168 --> 00:33:59,876
that there is this
technology out there

643
00:33:59,960 --> 00:34:02,168
that is far superior to us.

644
00:34:02,251 --> 00:34:05,835
That technology
isn't something we have.

645
00:34:05,918 --> 00:34:07,876
So, if not us, who or what?

646
00:34:08,001 --> 00:34:13,043
And what we're hearing about now
is just the tip of the iceberg.

647
00:34:13,168 --> 00:34:16,501
There have been consistently
a lot of reports

648
00:34:16,626 --> 00:34:20,960
of unidentified objects
under the ocean.

649
00:34:21,085 --> 00:34:22,501
People have seen them
from the shore,

650
00:34:22,585 --> 00:34:25,126
going into the sea
and coming out of the sea.

651
00:34:25,251 --> 00:34:29,543
We've all heard of UFOs because
they fly in our atmosphere,

652
00:34:29,668 --> 00:34:34,543
but what happens if they can hit
the oceans and go underwater?

653
00:34:34,668 --> 00:34:36,210
These are USOs.

654
00:34:36,335 --> 00:34:38,668
Unidentified submerged objects

655
00:34:38,751 --> 00:34:42,210
are objects that have
the ability to plunge

656
00:34:42,335 --> 00:34:45,376
right into the ocean
and disappear.

657
00:34:45,501 --> 00:34:48,543
This is something
that we cannot duplicate

658
00:34:48,710 --> 00:34:51,376
with our technology,
and so these objects

659
00:34:51,501 --> 00:34:54,210
are of very intense interest
because it means

660
00:34:54,335 --> 00:34:59,418
that a new technology is being
harnessed by some unknown party.

661
00:34:59,543 --> 00:35:03,168
They could be even,
perhaps, extraterrestrial.

662
00:35:03,251 --> 00:35:06,960
Extraterrestrial USOs?

663
00:35:07,085 --> 00:35:10,335
Flying into and out of
the world's oceans?

664
00:35:10,418 --> 00:35:12,585
For some, that may sound
like something

665
00:35:12,751 --> 00:35:14,126
out of science fiction.

666
00:35:14,251 --> 00:35:15,501
But curiously,

667
00:35:15,585 --> 00:35:18,043
more than a decade after
the Tic Tac incident,

668
00:35:18,168 --> 00:35:22,293
the United States Navy
continues to detect USOs

669
00:35:22,418 --> 00:35:24,668
off the coast
of Southern California.

670
00:35:25,960 --> 00:35:30,001
In July of 2019, Navy aircraft
flying in the same area

671
00:35:30,126 --> 00:35:32,376
recorded video
which appears to show

672
00:35:32,501 --> 00:35:36,751
an unidentified flying object
disappearing into the ocean.

673
00:35:39,751 --> 00:35:41,543
What's really
interesting about this

674
00:35:41,626 --> 00:35:43,043
is that all this is happening

675
00:35:43,126 --> 00:35:45,376
in a fairly small
geographical area.

676
00:35:45,501 --> 00:35:50,293
So you've got a series
of encounters

677
00:35:50,418 --> 00:35:52,626
happening off the coast
of San Diego.

678
00:35:52,751 --> 00:35:56,335
To have all this going on
in one very concentrated spot,

679
00:35:56,460 --> 00:35:59,710
one has to say,
is this just a coincidence

680
00:35:59,793 --> 00:36:01,501
or is there a connection?

681
00:36:01,585 --> 00:36:06,251
If there are, in fact,
extraterrestrial USOs

682
00:36:06,376 --> 00:36:08,585
lurking in this area,

683
00:36:08,710 --> 00:36:12,626
then where are they hiding
when they go underwater?

684
00:36:17,501 --> 00:36:19,793
Satellite imagery
reveals a strange

685
00:36:19,918 --> 00:36:24,168
underwater formation
only six miles off the coast.

686
00:36:25,335 --> 00:36:28,251
The three-mile-long anomaly
lies 2,000 feet

687
00:36:28,418 --> 00:36:30,293
below the surface
of the Pacific Ocean,

688
00:36:30,418 --> 00:36:33,210
and the discovery led
many to wonder

689
00:36:33,335 --> 00:36:35,751
if this formation
might actually be

690
00:36:35,918 --> 00:36:38,335
an artificial structure.

691
00:36:38,460 --> 00:36:39,501
A lot of people

692
00:36:39,585 --> 00:36:42,710
got very excited
by this discovery.

693
00:36:42,835 --> 00:36:44,460
It's really quite striking

694
00:36:44,585 --> 00:36:47,126
and it really
does look artificial.

695
00:36:47,251 --> 00:36:51,043
It looks like the thing's
got this huge flat roof.

696
00:36:51,168 --> 00:36:54,293
It looks like it's got
pillars or columns.

697
00:36:54,418 --> 00:36:55,668
And it makes you wonder,

698
00:36:55,751 --> 00:37:00,335
is this the remains of
some ancient civilization

699
00:37:00,418 --> 00:37:03,626
that's just hidden
by rising sea level?

700
00:37:04,960 --> 00:37:08,418
Or is it, as some believe,
an extraterrestrial base?

701
00:37:09,585 --> 00:37:12,668
If all these objects
are buzzing our aircraft,

702
00:37:12,793 --> 00:37:15,293
they must have
a base of operations.

703
00:37:15,418 --> 00:37:18,085
But you see, if they
have a base of operations

704
00:37:18,210 --> 00:37:20,543
as easily detected by us humans,

705
00:37:20,626 --> 00:37:23,376
it would sort of defeat
the purpose of observing us.

706
00:37:23,501 --> 00:37:26,293
So perhaps there's
an underwater base

707
00:37:26,418 --> 00:37:29,543
that is away from
prying eyes of humans,

708
00:37:29,668 --> 00:37:32,710
so that we don't interfere
with their plans.

709
00:37:32,876 --> 00:37:34,793
That cannot be ruled out.

710
00:37:36,918 --> 00:37:38,418
Is it really possible

711
00:37:38,585 --> 00:37:41,460
there are
extraterrestrial spacecraft

712
00:37:41,585 --> 00:37:45,501
lurking in the ocean, as members
of the U.S. military claim?

713
00:37:45,585 --> 00:37:48,043
As of now,
we can't say for sure.

714
00:37:49,543 --> 00:37:52,585
But sometimes the ocean's
depths reveal evidence

715
00:37:52,710 --> 00:37:56,376
which proves that
an incredible story is true.

716
00:37:56,501 --> 00:37:58,876
Like off the coast of India...

717
00:37:59,918 --> 00:38:01,751
...where archaeologists
rediscovered

718
00:38:01,918 --> 00:38:04,210
the ruins of a mythical

719
00:38:04,293 --> 00:38:10,168
underwater city.

720
00:38:10,251 --> 00:38:13,168
Perched on the shore
of the Arabian Sea

721
00:38:13,251 --> 00:38:16,293
sits the modern city of Dwarka.

722
00:38:17,501 --> 00:38:19,460
It was named
after a legendary city

723
00:38:19,585 --> 00:38:22,460
that was also called Dwarka.

724
00:38:22,585 --> 00:38:26,293
The sacred Hindu text
the Mahabharata

725
00:38:26,418 --> 00:38:28,710
explains that the legendary
city of Dwarka

726
00:38:28,793 --> 00:38:31,293
was said to be the dwelling
place of Lord Krishna

727
00:38:31,418 --> 00:38:34,585
before it sank into the sea
following a fantastic

728
00:38:34,751 --> 00:38:37,210
battle in the sky
between Krishna

729
00:38:37,376 --> 00:38:39,793
and another Hindu god
Lord Salva.

730
00:38:41,043 --> 00:38:44,751
For centuries that story was
believed to be merely a legend.

731
00:38:44,918 --> 00:38:47,876
That is, until 1983

732
00:38:47,960 --> 00:38:51,460
when underwater ruins
were discovered off the coast.

733
00:38:52,751 --> 00:38:56,293
Ruins which suggest that
the legendary city of Dwarka

734
00:38:56,418 --> 00:39:00,751
was not a myth
but rather a real place.

735
00:39:02,251 --> 00:39:03,751
S.R. Rao

736
00:39:03,876 --> 00:39:06,543
was an archaeologist,
a marine archaeologist

737
00:39:06,668 --> 00:39:10,335
working with the Archaeology
Institute in India.

738
00:39:11,835 --> 00:39:14,460
And he started the exploration

739
00:39:14,585 --> 00:39:17,210
from the shore
of present-day Dwarka.

740
00:39:17,293 --> 00:39:19,376
And on the floor of the ocean,

741
00:39:19,543 --> 00:39:22,876
on the seafloor
he found wall structures,

742
00:39:22,960 --> 00:39:27,710
blocks three foot by three foot,
probably a foot thick,

743
00:39:27,793 --> 00:39:32,835
stacked as if they were building
continuous wall structures.

744
00:39:32,918 --> 00:39:35,085
They could be city walls,
they could be street,

745
00:39:35,210 --> 00:39:38,126
building walls, um,
they could be walls of temples.

746
00:39:40,293 --> 00:39:43,918
The archaeologists are now
saying that they are perhaps

747
00:39:44,043 --> 00:39:47,376
datable to 9000 BCE.

748
00:39:48,376 --> 00:39:49,710
If it is true,

749
00:39:49,793 --> 00:39:52,835
the archaeological fact
supports the story.

750
00:39:52,918 --> 00:39:56,043
And that is what makes it
more interesting and more

751
00:39:56,168 --> 00:39:58,210
significant, this discovery.

752
00:39:59,501 --> 00:40:02,501
The discovery of sunken ruins
off the coast of Dwarka

753
00:40:02,626 --> 00:40:05,835
is proof that underwater
exploration can turn some myths

754
00:40:05,960 --> 00:40:07,710
into reality.

755
00:40:07,793 --> 00:40:12,210
Many experts believe that Dwarka
is just the tip of the iceberg,

756
00:40:12,293 --> 00:40:16,168
and that there are even more
secrets lurking in the deep

757
00:40:16,293 --> 00:40:17,460
that could challenge

758
00:40:17,585 --> 00:40:19,668
our understanding
of both our planet...

759
00:40:20,585 --> 00:40:22,876
...and human history.

760
00:40:23,001 --> 00:40:24,376
The biggest unanswered question

761
00:40:24,543 --> 00:40:26,210
regarding the oceans is,

762
00:40:26,376 --> 00:40:29,876
now that we've opened this door
to this scientific exploration,

763
00:40:30,001 --> 00:40:31,210
what can be found

764
00:40:31,376 --> 00:40:33,585
that will have some
impact on our own lives?

765
00:40:34,626 --> 00:40:37,210
Well, the oceans,
they drive weather

766
00:40:37,335 --> 00:40:39,668
and regulate temperature

767
00:40:39,793 --> 00:40:42,210
in ways that we don't
fully understand now,

768
00:40:42,376 --> 00:40:45,751
and the only way that we're
going to completely understand

769
00:40:45,918 --> 00:40:48,501
is to go down there
and to gather more data.

770
00:40:48,626 --> 00:40:50,460
And that's just one example.

771
00:40:50,585 --> 00:40:53,460
The ocean is constantly
throwing up surprises.

772
00:40:55,418 --> 00:40:57,710
Will we find remnants
of an ancient civilization

773
00:40:57,793 --> 00:40:59,168
that no one knew about?

774
00:40:59,251 --> 00:41:01,043
I don't know, but that

775
00:41:01,126 --> 00:41:04,668
unknown is what drives me,
because there's a chance

776
00:41:04,793 --> 00:41:05,960
that we'll find
something revolutionary

777
00:41:06,085 --> 00:41:07,043
at the bottom of the ocean

778
00:41:07,168 --> 00:41:08,793
that no one had ever
thought of before.

779
00:41:11,085 --> 00:41:12,876
Even though we are the first

780
00:41:13,001 --> 00:41:16,960
generation ever
to explore under the sea

781
00:41:17,085 --> 00:41:20,543
with any level
of technology and rigor,

782
00:41:20,668 --> 00:41:23,001
the deep sea still eludes us.

783
00:41:24,585 --> 00:41:25,876
And the good thing is,

784
00:41:26,001 --> 00:41:27,835
it's becoming more
and more accessible.

785
00:41:27,918 --> 00:41:30,626
Imagine what we can discover
in the next 50 years.

786
00:41:32,251 --> 00:41:34,835
So, what do you think?

787
00:41:34,918 --> 00:41:38,668
What still lies in the deepest,
darkest corners of the ocean?

788
00:41:38,751 --> 00:41:40,793
Well, in spite of
everything we've learned

789
00:41:40,918 --> 00:41:42,460
about the underwater world,

790
00:41:42,585 --> 00:41:45,460
we simply don't know
what else is down there

791
00:41:45,585 --> 00:41:46,918
waiting to be found.

792
00:41:47,043 --> 00:41:50,543
And that mystery is what
compels us to keep diving,

793
00:41:50,668 --> 00:41:54,918
to keep searching,
in the hope that one day

794
00:41:55,043 --> 00:41:57,626
we will uncover all
the secrets of the deep that,

795
00:41:57,751 --> 00:41:59,043
for the moment, remain...

796
00:41:59,168 --> 00:42:01,543
unexplained.

797
