Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:12,490 --> 00:00:13,790
Thrown out of orbit.
2
00:00:14,690 --> 00:00:17,490
Drifting into the outer reaches of
space.
3
00:00:18,070 --> 00:00:24,770
A world thrown into dark and cold in the
face of an eternal ice
4
00:00:24,770 --> 00:00:25,770
age.
5
00:00:34,190 --> 00:00:36,430
Leading minds join forces.
6
00:00:37,770 --> 00:00:41,770
To craft scientifically plausible
scenarios of Armageddon.
7
00:00:43,270 --> 00:00:49,950
And find the secrets to human salvation
in the
8
00:00:49,950 --> 00:00:51,710
face of ultimate disaster.
9
00:01:02,810 --> 00:01:06,490
When we take a look around the solar
system, it becomes very clear.
10
00:01:06,780 --> 00:01:08,820
that the Earth is in a very special
place.
11
00:01:09,460 --> 00:01:12,780
Its orbit is perfect for sustaining all
our life.
12
00:01:13,900 --> 00:01:17,140
So we're going to get there on time,
right? Yes, sir. We'll be out in about
13
00:01:17,140 --> 00:01:18,140
minutes.
14
00:01:18,580 --> 00:01:22,640
If something were to happen to take the
Earth outside of this perfect zone,
15
00:01:22,880 --> 00:01:24,240
everything would change.
16
00:01:24,960 --> 00:01:28,360
And the first signs of such a change
could take us by surprise.
17
00:01:49,990 --> 00:01:55,450
There are forces in the universe that
we're only beginning to comprehend.
18
00:01:55,970 --> 00:01:59,590
Forces powerful enough to change
mankind's course forever.
19
00:02:00,050 --> 00:02:01,550
Why are they asking about our altitude?
20
00:02:01,870 --> 00:02:04,510
You see right there in front of us?
That's the landing strip right there.
21
00:02:04,510 --> 00:02:05,510
going to land there.
22
00:02:35,020 --> 00:02:39,120
Reports of multiple plane crashes around
the world and several massive ships
23
00:02:39,120 --> 00:02:40,120
have run aground.
24
00:02:43,320 --> 00:02:47,440
The National Transportation Safety Board
has still issued no official
25
00:02:47,440 --> 00:02:52,500
explanation for the worldwide
navigational disaster that began 48
26
00:02:53,760 --> 00:02:57,200
Anonymous sources at the Department of
Defense have confirmed that the GPS
27
00:02:57,200 --> 00:03:01,180
networks across the globe, which affect
everything from our smartphones to major
28
00:03:01,180 --> 00:03:04,180
transportation hubs, have been
malfunctioning all at once.
29
00:03:05,480 --> 00:03:09,420
Officials are unsure what may be causing
the malfunction at this time.
30
00:03:13,540 --> 00:03:18,760
What if we suddenly discovered that all
of our navigation systems are GPS
31
00:03:18,760 --> 00:03:23,820
devices? We're wrong. We're sending it
in the wrong directions, putting us in
32
00:03:23,820 --> 00:03:25,500
the wrong places worldwide.
33
00:03:26,820 --> 00:03:31,700
We would immediately have to ask the
question of whether something has
34
00:03:31,700 --> 00:03:32,780
to our own satellites.
35
00:03:39,690 --> 00:03:41,130
Good day. Let's begin.
36
00:03:41,330 --> 00:03:42,430
We have a lot to cover.
37
00:03:42,690 --> 00:03:47,730
72 hours ago, a massive failure in the
Global Positioning Satellite Network led
38
00:03:47,730 --> 00:03:50,470
to a worldwide disaster in navigation.
39
00:03:53,170 --> 00:03:58,710
We have discovered that this occurred
because our GPS satellites are no longer
40
00:03:58,710 --> 00:03:59,710
where we place them.
41
00:04:00,210 --> 00:04:03,790
In fact, every satellite has been
displaced.
42
00:04:10,090 --> 00:04:13,870
We'd have to ask the question of whether
or not something has actually happened
43
00:04:13,870 --> 00:04:14,870
to the Earth itself.
44
00:04:18,350 --> 00:04:21,630
This disruption is not limited to just
the satellites.
45
00:04:22,290 --> 00:04:27,470
Ladies and gentlemen, all measurable
bodies within our solar system have to
46
00:04:27,470 --> 00:04:29,950
degree been pulled out of their standard
orbit.
47
00:04:31,490 --> 00:04:33,270
This includes the Earth.
48
00:04:40,810 --> 00:04:44,850
That Earth could be pulled out of its
orbit around the sun is extremely
49
00:04:44,850 --> 00:04:49,610
unlikely. But there are things in
existence powerful enough to move entire
50
00:04:49,610 --> 00:04:53,170
planets, things that we're only
beginning to understand.
51
00:04:53,930 --> 00:04:57,790
One of those things is something called
dark matter.
52
00:05:01,010 --> 00:05:07,310
Dark matter is this mysterious stuff
that actually constitutes
53
00:05:07,310 --> 00:05:09,770
85 % of the mass.
54
00:05:10,300 --> 00:05:11,300
in our universe.
55
00:05:11,560 --> 00:05:16,280
So in our universe is normal matter,
stuff we're made of, the stuff planets
56
00:05:16,280 --> 00:05:17,280
stars are made of.
57
00:05:17,320 --> 00:05:22,940
But then, over many decades of research,
astronomers have realized there has to
58
00:05:22,940 --> 00:05:25,660
be other stuff helping hold everything
together.
59
00:05:26,320 --> 00:05:33,280
We know that there's this mysterious
matter, this extra mass out there, but
60
00:05:33,280 --> 00:05:36,840
can't quite put our finger on it. We
don't know exactly what it is.
61
00:05:38,200 --> 00:05:39,500
It's ghost matter.
62
00:05:39,960 --> 00:05:45,120
It doesn't glow, it doesn't reflect
light, but it adds to the gravitating
63
00:05:45,120 --> 00:05:46,120
of objects.
64
00:05:46,400 --> 00:05:51,640
And if such a clump of material passes
through or near our solar system, its
65
00:05:51,640 --> 00:05:54,000
gravitational force could have a
profound effect.
66
00:05:56,120 --> 00:06:00,480
It is our conclusion that these
perturbations are being caused due to a
67
00:06:00,480 --> 00:06:03,320
concentration of dark matter near our
solar system.
68
00:06:04,240 --> 00:06:09,180
It would pull gravitation on all of the
planets and offset the planets.
69
00:06:09,680 --> 00:06:16,400
from their current rather delicate
orbit. In time, this instability could
70
00:06:16,400 --> 00:06:21,440
grow and manifest itself as orbits that
slowly expand.
71
00:06:22,440 --> 00:06:27,400
So what would happen if Earth's orbit
was altered, taking us out of the only
72
00:06:27,400 --> 00:06:29,640
path that Earth's life has ever known?
73
00:06:33,960 --> 00:06:38,460
Our very existence is made possible
because we happen to live at the perfect
74
00:06:38,460 --> 00:06:43,180
distance from the sun. This thin band of
livable space is known as the
75
00:06:43,180 --> 00:06:44,180
Goldilocks zone.
76
00:06:44,300 --> 00:06:48,840
It's not too hot. It's not too cold. For
all life on Earth, it's just right.
77
00:06:50,740 --> 00:06:55,220
If Earth wouldn't leave the Goldilocks
zone, life for humankind and everything
78
00:06:55,220 --> 00:06:57,100
we know would be changed forever.
79
00:06:57,900 --> 00:07:00,660
The size of the orbit was to grow.
80
00:07:01,520 --> 00:07:06,840
then the winters would get much, much
colder, and the global temperatures
81
00:07:06,840 --> 00:07:08,660
drop significantly.
82
00:07:12,140 --> 00:07:18,340
Projections show that Earth's orbit will
continue to spiral away from the sun.
83
00:07:18,760 --> 00:07:21,660
As it does, Earth's temperature will
fall.
84
00:07:22,100 --> 00:07:24,660
It will drop one degree per year.
85
00:07:25,260 --> 00:07:27,540
In 20 years, it will be freezing at the
equator.
86
00:07:28,000 --> 00:07:34,500
96 years from now, the average global
temperature could be minus 430 degrees.
87
00:07:41,560 --> 00:07:48,520
As we begin to move away from the sun,
out into space, our source of
88
00:07:48,520 --> 00:07:53,020
light and heat would not go away all at
once, but it would begin to fade. Our
89
00:07:53,020 --> 00:07:54,520
biosphere would begin to change.
90
00:07:55,000 --> 00:07:56,580
altering our ecosystem forever.
91
00:07:57,740 --> 00:08:04,180
In the short term, we see a
rearrangement of both plant and animal
92
00:08:04,180 --> 00:08:09,720
Earth. A drop in average global
temperatures would start this chain
93
00:08:09,720 --> 00:08:10,720
going.
94
00:08:11,940 --> 00:08:15,180
Where it stops, we don't know.
95
00:08:19,310 --> 00:08:23,610
Six months after the dark matter
incident, bizarre animal migrations are
96
00:08:23,610 --> 00:08:27,330
occurring all over the globe. Birds of
giraffe have begun leaving protected
97
00:08:27,330 --> 00:08:31,710
reserves in South Africa, becoming
targets for poachers. Thousands of birds
98
00:08:31,710 --> 00:08:34,510
dropped from the sky yesterday on
Edinburgh, Pennsylvania.
99
00:08:35,070 --> 00:08:39,510
100 ,000 whales beached themselves along
the Chilean coast.
100
00:08:39,830 --> 00:08:43,750
Scientists are blaming these phenomenon
on the alteration in the Earth's orbit
101
00:08:43,750 --> 00:08:44,870
and the changing temperatures.
102
00:08:46,520 --> 00:08:50,560
Religious fundamentalism is on the rise
and many people are preaching to the
103
00:08:50,560 --> 00:08:51,560
dead.
104
00:09:02,380 --> 00:09:08,980
As Earth spirals away from the sun
105
00:09:08,980 --> 00:09:12,940
and temperatures begin to drop, many of
the effects would be surprising.
106
00:09:13,610 --> 00:09:18,130
As that happens, the coldest places on
Earth, the poles, would begin to lose
107
00:09:18,130 --> 00:09:19,630
their ability to support life.
108
00:09:20,750 --> 00:09:25,410
One thing's for sure, you definitely
could have some movement of that
109
00:09:25,410 --> 00:09:29,410
and interactions unlike some we've seen
before.
110
00:09:41,040 --> 00:09:45,980
The Arctic is going to cool at a faster
pace than in the lower latitudes. But
111
00:09:45,980 --> 00:09:48,480
don't be mistaken, everywhere on Earth
will be affected.
112
00:10:14,250 --> 00:10:19,750
You might think that a drop of just a
few degrees is insignificant, but we're
113
00:10:19,750 --> 00:10:22,650
talking about the average temperature of
the entire planet.
114
00:10:26,270 --> 00:10:31,150
In the middle of the last ice age, the
planet Earth was only 5 degrees Celsius
115
00:10:31,150 --> 00:10:32,810
colder than it is today.
116
00:10:33,350 --> 00:10:35,890
So that's a really narrow window.
117
00:10:37,390 --> 00:10:42,170
A drop of 2 degrees Fahrenheit in the
global temperature could mean cold snaps
118
00:10:42,170 --> 00:10:44,690
of 20 to 30 degrees cooler in your
hometown.
119
00:10:49,970 --> 00:10:54,970
People who are unaccustomed to winter
conditions, at first it's kind of
120
00:10:54,970 --> 00:10:57,450
because it's so extreme and so
different.
121
00:10:58,630 --> 00:11:02,910
It was another week of record -breaking
summertime cold throughout the
122
00:11:02,910 --> 00:11:04,310
Midwestern United States.
123
00:11:05,070 --> 00:11:08,870
Some, like these folks shown here in
Evansville, Indiana, kept their spirits
124
00:11:08,870 --> 00:11:13,190
high by having some fun outside and
posting it online for others to see.
125
00:11:13,690 --> 00:11:15,410
I have a cup of boiling hot water.
126
00:11:16,610 --> 00:11:17,610
Check this out.
127
00:11:20,150 --> 00:11:21,430
Negative 19 degrees.
128
00:11:21,970 --> 00:11:23,610
Boiling water turns into mist.
129
00:11:25,670 --> 00:11:28,810
And then pretty quickly thereafter, it
gets old.
130
00:11:30,450 --> 00:11:33,490
It's hard to go outside without putting
on...
131
00:11:33,920 --> 00:11:35,600
some pretty extreme clothing.
132
00:11:36,140 --> 00:11:40,740
We can handle putting on warmer clothes
and layering before we go outside, but
133
00:11:40,740 --> 00:11:45,220
most people won't realize the dangers of
a cooling planet until the cold takes
134
00:11:45,220 --> 00:11:46,820
away something that we can't live
without.
135
00:11:48,940 --> 00:11:49,940
Our food.
136
00:12:01,360 --> 00:12:05,620
Colder temperatures are going to bring
later freezes as plants are trying to
137
00:12:05,620 --> 00:12:09,700
germinate, so we're going to shorten the
growing season, and all of that is
138
00:12:09,700 --> 00:12:12,640
going to conspire to limit the amount of
food grown.
139
00:12:13,480 --> 00:12:18,040
Despite all of our technological
advances, our food supply chain is still
140
00:12:18,040 --> 00:12:19,040
fragile.
141
00:12:19,460 --> 00:12:23,420
In what's become the second straight
year of uncommonly cold temperatures for
142
00:12:23,420 --> 00:12:27,080
Europe's farmers, resulting crop
failures are affecting millions.
143
00:12:28,110 --> 00:12:31,870
Britons have been warned to brace
themselves for sticker shock at food
144
00:12:31,870 --> 00:12:36,430
at some of the worst hit areas, or
reporting prices rising by 100 % in a
145
00:12:36,430 --> 00:12:37,430
of days.
146
00:12:40,110 --> 00:12:43,670
In the short term, a food shortage would
cause prices to skyrocket.
147
00:12:45,510 --> 00:12:49,430
Anyone with enough money would buy as
much food as they could and stockpile
148
00:12:49,530 --> 00:12:52,290
and the poor would begin to starve.
149
00:12:54,870 --> 00:12:57,630
Riots and looting could break out
anywhere food is stored.
150
00:13:03,670 --> 00:13:10,670
It will lead in short order to violence,
and this will
151
00:13:10,670 --> 00:13:12,990
in turn lead to a breakdown of
government.
152
00:13:15,750 --> 00:13:19,570
So there's no good or easy way out of
that process.
153
00:13:21,740 --> 00:13:25,780
And that will set in motion a fearsome
mess.
154
00:13:27,400 --> 00:13:34,320
No matter what is done, if people
believe that their family and loved ones
155
00:13:34,320 --> 00:13:39,660
will die or they'll be in jeopardy,
they're not going to accept any way of
156
00:13:39,660 --> 00:13:44,500
this. People would begin to, I hate to
say it, but I think they would panic.
157
00:13:50,860 --> 00:13:54,880
While we're fighting amongst ourselves,
a much bigger problem is growing worse.
158
00:13:55,080 --> 00:13:59,940
For six years, we've drifted away from
our sun, moving further and further into
159
00:13:59,940 --> 00:14:00,940
the cold of space.
160
00:14:01,000 --> 00:14:05,640
The freezing at the poles is
intensifying and moving down into the
161
00:14:05,640 --> 00:14:06,640
areas.
162
00:14:06,900 --> 00:14:10,360
Survivors are running out of time to
find places warm enough to stay alive.
163
00:14:26,350 --> 00:14:31,930
I think we're going to see a mass exodus
of people heading for the warmest place
164
00:14:31,930 --> 00:14:36,270
they can find. So the tropics and the
countries around the tropics are going
165
00:14:36,270 --> 00:14:38,090
be inundated with immigrants.
166
00:14:39,730 --> 00:14:46,510
And that, of course, would be incredibly
disruptive, tremendously threatening to
167
00:14:46,510 --> 00:14:50,630
people who already live in the places
that the exodus wants to move into.
168
00:14:51,950 --> 00:14:56,390
Major highways in the Phoenix area are
at a standstill for miles as a massive
169
00:14:56,390 --> 00:15:01,330
number of Arizona residents began their
exodus to warmer areas following a
170
00:15:01,330 --> 00:15:02,670
national emergency announcement.
171
00:15:03,370 --> 00:15:07,610
I was planning on heading over the West
Coast, but I don't think I'm going to
172
00:15:07,610 --> 00:15:08,610
make it now.
173
00:15:09,250 --> 00:15:13,750
It's been snowing all through the night
and all day. It hasn't let up at all.
174
00:15:17,270 --> 00:15:19,310
The people who hang...
175
00:15:19,560 --> 00:15:23,500
back and tough it out, I think you're
going to end up having a much harder
176
00:15:23,500 --> 00:15:27,460
existence. It's going to be a very
difficult place to live.
177
00:15:29,080 --> 00:15:33,800
Even in regions that are normally warm,
people will be unprepared for the rapid
178
00:15:33,800 --> 00:15:35,120
cold snaps headed their way.
179
00:16:20,750 --> 00:16:24,390
It's now been a decade of global cooling
on planet Earth, and the average
180
00:16:24,390 --> 00:16:26,090
temperature has plummeted by 10 degrees.
181
00:16:27,330 --> 00:16:31,310
Snow and ice are blanketing North
America from northern Canada to
182
00:16:36,830 --> 00:16:40,050
By now, less than half the Earth's
population is still alive.
183
00:16:50,990 --> 00:16:56,310
You know, some places along the equator
might be happy for a while because their
184
00:16:56,310 --> 00:16:58,130
temperatures are reduced a little bit.
185
00:16:59,230 --> 00:17:05,550
But where the majority of the population
is, is going to get a lot colder. Those
186
00:17:05,550 --> 00:17:07,250
people are not going to be happy.
187
00:17:10,690 --> 00:17:15,910
We have this clash between the cold air
over the continent and the warm, moist
188
00:17:15,910 --> 00:17:19,190
air out over the ocean. We might see it
get a lot stormier.
189
00:17:20,930 --> 00:17:23,970
So the Earth is going to respond in
dramatic ways.
190
00:17:31,370 --> 00:17:35,450
Ultimately, as we get farther and
farther from the sun, we will get to the
191
00:17:35,450 --> 00:17:37,910
where all of the precipitation does fall
as snow.
192
00:17:39,890 --> 00:17:43,650
Think about that for a second. There
might never be rain showers on this
193
00:17:43,650 --> 00:17:48,170
again. At a certain point, as the
freezing intensifies and marches towards
194
00:17:48,170 --> 00:17:52,250
equator, the only precipitation will be
snow, and the only season will be
195
00:17:52,250 --> 00:17:53,250
winter.
196
00:17:56,590 --> 00:18:02,910
Instead of infecting places like Seattle
and Chicago, they'll be more running
197
00:18:02,910 --> 00:18:05,170
along Houston, Miami.
198
00:18:17,770 --> 00:18:21,950
They would be faced with snows that
they'd never seen before, and they'd
199
00:18:21,950 --> 00:18:23,830
develop means of removing that snow.
200
00:18:25,490 --> 00:18:27,670
When it snows, it doesn't melt.
201
00:18:28,210 --> 00:18:33,470
And it piles up and piles up and piles
up, and the bottom of that snowfall
202
00:18:33,470 --> 00:18:34,470
into ice.
203
00:18:38,130 --> 00:18:43,150
The weight of those ice sheets and
gravitational forces will spread that
204
00:18:43,830 --> 00:18:45,830
down into the main city.
205
00:18:46,030 --> 00:18:48,290
You're going to start to see glaciers
forming around you.
206
00:19:12,270 --> 00:19:15,970
Hundreds of terrified residents were
barricaded into their homes today in
207
00:19:15,970 --> 00:19:19,890
Jackson, Mississippi as massive sheets
of ice surrounded entire neighborhoods.
208
00:19:20,270 --> 00:19:25,030
Much of this population could be at high
risk for even death, staying in their
209
00:19:25,030 --> 00:19:26,930
home for that long with no heat.
210
00:19:27,530 --> 00:19:31,170
Volunteer rescue teams are working with
the National Guard into the night to
211
00:19:31,170 --> 00:19:32,490
find those still missing.
212
00:19:34,290 --> 00:19:37,450
This drift is over 20 feet high.
213
00:19:37,690 --> 00:19:39,530
You see he's right at the top.
214
00:19:39,930 --> 00:19:40,970
of the edge of the roof.
215
00:19:44,470 --> 00:19:51,210
As more and more of the planet is
encased with ice permanently, the
216
00:19:51,210 --> 00:19:53,250
impact is going to be catastrophic.
217
00:19:54,030 --> 00:19:56,150
The roads will be impassable.
218
00:19:57,050 --> 00:20:00,590
The power would be terminated.
219
00:20:01,070 --> 00:20:07,990
If the people did not have a way to get
in from the cold, starvation will kill.
220
00:20:08,590 --> 00:20:10,350
And the cold will kill.
221
00:20:11,130 --> 00:20:12,130
They would perish.
222
00:20:22,050 --> 00:20:25,850
With nowhere to run from the cold,
people would begin to suffer from the
223
00:20:25,850 --> 00:20:27,510
physical effects of the freezing
temperatures.
224
00:20:28,710 --> 00:20:33,150
At 40 below, our skin freezes almost
instantly, so it can't be exposed.
225
00:20:33,590 --> 00:20:37,490
It's hard to go outside, and you have to
cover pretty much every...
226
00:20:38,180 --> 00:20:41,560
square inch of exposed skin to avoid
getting frostbitten.
227
00:20:46,460 --> 00:20:52,100
Frostbite is when the actual cells in
your skin start to freeze, the water in
228
00:20:52,100 --> 00:20:56,340
those cells. If it goes deep enough and
you actually kill the cells in the skin
229
00:20:56,340 --> 00:21:00,520
that make new skin cells, then you end
up with frostbite.
230
00:21:00,970 --> 00:21:05,570
You tend to get frostbitten first in
your fingers and your nose and your ears
231
00:21:05,570 --> 00:21:10,510
they're exposed because your body does
shut down the circulation to the
232
00:21:10,510 --> 00:21:11,510
extremities first.
233
00:21:11,650 --> 00:21:15,230
You can live without arms, but you can't
live without your vital organs.
234
00:21:26,000 --> 00:21:30,200
A drop of only 4 degrees Fahrenheit in
core body temperature can cause
235
00:21:30,200 --> 00:21:33,400
uncontrollable shivering, confusion, and
weakness.
236
00:21:35,120 --> 00:21:39,760
As your organs begin to cool, death can
strike long before your body actually
237
00:21:39,760 --> 00:21:40,760
freezes.
238
00:21:57,840 --> 00:22:02,540
As the Earth begins to cool, it can
actually be an accelerating process.
239
00:22:02,900 --> 00:22:08,880
And this is because frozen water
reflects more sunlight than liquid
240
00:22:09,420 --> 00:22:15,380
As the ice caps expand, the Earth
becomes more and more reflective, and so
241
00:22:15,380 --> 00:22:17,980
actually absorbs even less sunlight.
242
00:22:18,400 --> 00:22:23,340
As glacier -like ice sheets move beyond
30 degrees latitude, covering places
243
00:22:23,340 --> 00:22:26,140
like Houston, New Orleans, and Cairo,
244
00:22:26,940 --> 00:22:28,400
we would reach a tipping point.
245
00:22:30,960 --> 00:22:32,700
And it's a runaway process.
246
00:22:33,180 --> 00:22:36,340
Sometimes it's called a snowball earth
effect.
247
00:22:43,380 --> 00:22:49,180
With that tipping point, things could
move at a faster pace and make it more
248
00:22:49,180 --> 00:22:52,580
difficult for the human race to keep up
with it.
249
00:22:53,160 --> 00:22:56,760
We're heading off into territory that we
cannot return from.
250
00:22:56,980 --> 00:23:00,140
I think at that point we should be very
worried.
251
00:23:25,660 --> 00:23:29,580
Ultimately, as we get farther and
farther from the sun, we will get to the
252
00:23:29,580 --> 00:23:32,500
where everything on the surface is
freezing.
253
00:23:34,740 --> 00:23:36,540
Ice is enveloping the planet.
254
00:23:36,780 --> 00:23:39,960
We're running out of time. But what
options do we have?
255
00:23:40,300 --> 00:23:44,280
The surface is becoming too cold for
even the strongest to survive.
256
00:24:06,440 --> 00:24:11,000
about places where people have somehow
been generating energy or heat. I'm
257
00:24:11,000 --> 00:24:14,560
getting conflicting reports on where
these locations are, but I'll keep you
258
00:24:14,560 --> 00:24:16,080
posted as soon as I hear more.
259
00:24:16,280 --> 00:24:17,280
Stay warm.
260
00:24:17,980 --> 00:24:19,580
Survivor Radio signing off.
261
00:24:23,660 --> 00:24:26,380
It comes down to having a sufficiency of
energy.
262
00:24:26,880 --> 00:24:30,320
It really does. If you haven't got
energy, you've got nothing. If you've
263
00:24:30,320 --> 00:24:33,860
energy, then you've got a chance.
264
00:24:36,430 --> 00:24:40,150
If we're losing the sun's power, what do
we do? Well, we know we have fossil
265
00:24:40,150 --> 00:24:45,350
fuels, but those are finite. We know we
have nuclear power, but that's tricky.
266
00:24:45,650 --> 00:24:47,930
It's a problem we haven't faced before.
267
00:24:48,130 --> 00:24:51,230
Many things we rarely think about are
powered by our sun.
268
00:24:51,950 --> 00:24:57,050
Photosynthesis, light so we can feed,
heat to keep us from freezing. All of
269
00:24:57,050 --> 00:24:59,070
now has to be generated another way.
270
00:24:59,350 --> 00:25:04,550
So we're going to have to start thinking
seriously about really producing a lot
271
00:25:04,550 --> 00:25:05,479
more energy.
272
00:25:05,480 --> 00:25:06,520
than we've ever produced before.
273
00:25:07,500 --> 00:25:11,960
If we're clever enough, we can tap into
geothermal energy sources.
274
00:25:13,480 --> 00:25:17,780
The Earth itself is an energy source.
275
00:25:20,360 --> 00:25:25,540
Geothermal energy, the heat of the
planet, has been with us forever, and
276
00:25:25,540 --> 00:25:27,300
not going away anytime soon.
277
00:25:29,360 --> 00:25:33,560
The center of the Earth is about 9 ,000
degrees Fahrenheit.
278
00:25:34,350 --> 00:25:38,370
There's a lot of heat there that we
could use to power our needs on the
279
00:25:38,450 --> 00:25:40,810
but we have to get it from there to the
surface.
280
00:25:42,670 --> 00:25:47,990
One of the things you can do in this
scenario is you drill down a ways, and
281
00:25:47,990 --> 00:25:50,370
you get deep enough, you can get a lot
of heat out of it.
282
00:25:50,690 --> 00:25:53,070
And you can, in fact, boil water away.
283
00:25:53,370 --> 00:25:58,450
And you can use that steam to drive a
turbine to create energy and
284
00:26:02,730 --> 00:26:09,090
It's going to give you the heat to power
energy, light, and grow the crops you
285
00:26:09,090 --> 00:26:10,090
need to survive.
286
00:26:12,370 --> 00:26:16,770
So if we know the energy we desperately
need exists underground, where is the
287
00:26:16,770 --> 00:26:20,050
best place to access it in order to save
the maximum number of lives?
288
00:26:23,710 --> 00:26:28,570
Any place where you see a lot of
volcanic action is where you would want
289
00:26:28,570 --> 00:26:29,570
to find that heat.
290
00:26:31,660 --> 00:26:35,920
The place you would most want to look
would be around the Ring of Fire, which
291
00:26:35,920 --> 00:26:39,120
essentially encircles the Pacific Basin.
292
00:26:40,660 --> 00:26:46,300
There are some major geothermal mining
systems that generate electricity for
293
00:26:46,300 --> 00:26:47,300
Southern California.
294
00:26:48,080 --> 00:26:51,580
It's a relatively untapped but very
abundant source of energy.
295
00:26:53,200 --> 00:26:57,940
The dream scenario would be to find a
hotspot with large infrastructure near a
296
00:26:57,940 --> 00:26:59,820
city that can house a large number of
survivors.
297
00:27:01,200 --> 00:27:02,980
And we're in luck. It exists.
298
00:27:04,580 --> 00:27:08,860
The largest geothermal development in
the world is the geysers, which lies
299
00:27:08,860 --> 00:27:11,480
72 miles north of San Francisco in
California.
300
00:27:14,500 --> 00:27:19,740
You want to be able to tap the most
available energy. And if it's near
301
00:27:19,740 --> 00:27:24,540
areas such as San Francisco, then that's
what you go for. We know we can use
302
00:27:24,540 --> 00:27:27,400
that geothermal heat for all sorts of
things once we tap it.
303
00:27:27,770 --> 00:27:31,590
But we'd still have to find a way to
keep that heat in and insulate ourselves
304
00:27:31,590 --> 00:27:32,590
from the cold.
305
00:27:36,170 --> 00:27:41,830
Certainly one option would be to build a
geodesic dome.
306
00:27:42,550 --> 00:27:47,130
We've built domes like this on a smaller
scale in the Arctic. These geodesic
307
00:27:47,130 --> 00:27:50,830
domes are built in the Arctic to keep
people safe from the frigid temperatures
308
00:27:50,830 --> 00:27:52,210
and extreme winds.
309
00:27:53,640 --> 00:28:00,260
And if a geodesic dome has the right
geometric configuration, then that's the
310
00:28:00,260 --> 00:28:01,019
way to go.
311
00:28:01,020 --> 00:28:07,180
But there needs to be some creative
engineering to best secure that heat and
312
00:28:07,180 --> 00:28:09,120
ward off the cold from outside.
313
00:28:10,980 --> 00:28:15,920
Now think bigger. If you want to protect
a large area, an effective way to do it
314
00:28:15,920 --> 00:28:20,000
might be to create a large, massive
geodesic dome.
315
00:28:20,220 --> 00:28:23,190
One. large enough to fit over an entire
city.
316
00:28:24,850 --> 00:28:28,370
The buildings inside could be heated
with geothermal energy, which would keep
317
00:28:28,370 --> 00:28:29,610
everyone warm and safe.
318
00:28:33,550 --> 00:28:37,330
The dome would have to be made from a
cutting -edge material designed to
319
00:28:37,330 --> 00:28:38,410
withstand extreme cold.
320
00:28:39,470 --> 00:28:44,790
There are ideas for how you might put
carbon nanotubes or other things
321
00:28:44,790 --> 00:28:48,230
impregnated in some of these materials
to make them stronger and more robust at
322
00:28:48,230 --> 00:28:49,230
low temperatures.
323
00:28:52,690 --> 00:28:55,990
We'll need these materials because up on
the surface the world is going to be a
324
00:28:55,990 --> 00:28:57,370
much different place than we've ever
known
325
00:28:57,370 --> 00:29:06,350
As
326
00:29:06,350 --> 00:29:13,650
we
327
00:29:13,650 --> 00:29:18,370
get further and further out the Sun
begins to look like a dim ball of white
328
00:29:18,370 --> 00:29:19,630
light in the sky
329
00:29:20,620 --> 00:29:25,620
It's been 35 years since the Earth began
moving away from the sun. Over 98 % of
330
00:29:25,620 --> 00:29:28,700
the world's population has either
starved or frozen to death.
331
00:29:31,360 --> 00:29:35,080
Those people who are not in the geodesic
dome, but have somehow managed to
332
00:29:35,080 --> 00:29:38,340
protect themselves from the cold up to
now, won't be safe for very long.
333
00:29:39,380 --> 00:29:44,220
One thing that is almost certain to
happen is that the assemblage of
334
00:29:44,220 --> 00:29:47,280
and infrastructure will increasingly
start to fail.
335
00:29:47,770 --> 00:29:53,530
The reason for that is that we build
largely with a very small number of
336
00:29:53,530 --> 00:29:58,210
of material, generally concrete, glass,
and steel.
337
00:29:58,790 --> 00:30:04,970
We know the properties of these
materials, but we design and use them
338
00:30:04,970 --> 00:30:06,630
fairly narrow temperature range.
339
00:30:06,890 --> 00:30:10,930
Steel, which seems really strong in our
everyday application, when you get to be
340
00:30:10,930 --> 00:30:14,170
100 degrees below zero, can actually be
very fragile and very brittle.
341
00:30:15,120 --> 00:30:20,040
Water will infiltrate the pores of
concrete and buildings will fall down.
342
00:30:20,480 --> 00:30:21,660
Bridges will fail.
343
00:30:22,540 --> 00:30:26,800
Standing in temperatures this cold would
be like soaking these structures in
344
00:30:26,800 --> 00:30:27,800
liquid nitrogen.
345
00:30:28,000 --> 00:30:31,600
Eventually, the slightest tap can make
them shatter like glass.
346
00:31:05,230 --> 00:31:06,850
and another one right here in Africa.
347
00:31:07,410 --> 00:31:08,530
There could be others.
348
00:31:09,610 --> 00:31:12,270
Coordinates will be on loop at the end
of this message.
349
00:31:12,730 --> 00:31:14,050
I'm headed under myself.
350
00:31:14,570 --> 00:31:15,570
Stay alive.
351
00:31:16,030 --> 00:31:17,790
Survivor Radio, signing off.
352
00:31:34,600 --> 00:31:39,560
By now, Earth has cooled by over 100
degrees Fahrenheit, and its
353
00:31:39,560 --> 00:31:41,700
to an icy rock is well underway.
354
00:31:41,900 --> 00:31:45,980
The planet barely resembles the place
that survivors remember from their
355
00:31:45,980 --> 00:31:51,480
days. But some have found a way to hold
off the cold inside geodomes using heat
356
00:31:51,480 --> 00:31:52,680
from inside the Earth.
357
00:31:53,140 --> 00:31:56,820
While domed cities will save many lives,
they won't be the answer for everyone.
358
00:31:57,000 --> 00:32:00,400
There are only a handful of cities near
active geothermal areas.
359
00:32:00,660 --> 00:32:02,400
Not everyone will get a spot inside.
360
00:32:02,920 --> 00:32:04,840
So what options are there for the rest
of mankind?
361
00:32:07,160 --> 00:32:08,840
We're not entirely out of luck.
362
00:32:09,180 --> 00:32:13,420
With or without a dome, we still have
our energy source at the Earth's core
363
00:32:13,420 --> 00:32:15,840
places where that energy is close to the
surface.
364
00:32:17,160 --> 00:32:21,620
The surface is too dangerous to stay on
for any real amount of time. So the most
365
00:32:21,620 --> 00:32:24,940
important thing for Earth's remaining
human beings is to get underground.
366
00:32:39,660 --> 00:32:44,120
Now you go down into mines that go a
mile or more underground and it gets
367
00:32:44,120 --> 00:32:45,120
warmer.
368
00:32:45,720 --> 00:32:51,340
You go near geothermal vents and such
and it can be considerably warmer. So
369
00:32:51,340 --> 00:32:53,700
there are some places to take cover.
370
00:32:53,960 --> 00:32:58,200
The Earth is a great insulator. It is a
great thermal insulator because it stays
371
00:32:58,200 --> 00:33:00,200
at a fairly constant temperature under
the ground.
372
00:33:00,440 --> 00:33:05,820
So given enough energy, given the right
sort of equipment, we can engineer the
373
00:33:05,820 --> 00:33:06,820
spaces.
374
00:33:11,500 --> 00:33:15,080
But tunneling holes deep underground is
a very delicate business.
375
00:33:15,460 --> 00:33:19,640
We're not just talking about a single
mine. We're talking about building
376
00:33:19,640 --> 00:33:25,200
underground cityscapes. As we dig deeper
into Earth to access more energy, we're
377
00:33:25,200 --> 00:33:27,560
going to have a whole new set of
problems on our hands.
378
00:33:31,300 --> 00:33:35,400
While our planet's surface continues its
deep freeze, people might find safe
379
00:33:35,400 --> 00:33:38,020
haven underground by building networks
of tunnels.
380
00:33:40,600 --> 00:33:44,280
Engineers will have to move very quickly
to accommodate the growing numbers of
381
00:33:44,280 --> 00:33:45,620
survivors who want to move in.
382
00:33:48,360 --> 00:33:50,800
But the deeper we go, the greater the
risk.
383
00:33:54,820 --> 00:33:59,640
How far below grade are we? We've been
getting 300 feet a day, but we've had to
384
00:33:59,640 --> 00:34:02,820
cut production a little bit. We're real
close to a methane pocket.
385
00:34:03,140 --> 00:34:07,340
We've altered the alignment slightly so
we can get around it. It's killing our
386
00:34:07,340 --> 00:34:08,340
production.
387
00:34:09,030 --> 00:34:12,710
Workers digging those tunnels would be
under immense pressure to move quickly,
388
00:34:12,850 --> 00:34:15,949
and this would increase the probability
of accidents occurring.
389
00:34:16,350 --> 00:34:19,469
We can't go very long like this. We've
got to go, man.
390
00:34:21,469 --> 00:34:25,030
And when you're deep below the surface,
one false step could have serious
391
00:34:25,030 --> 00:34:26,030
consequences.
392
00:34:30,110 --> 00:34:31,630
We've got a problem in tunnel 112.
393
00:34:59,210 --> 00:35:03,310
The deeper down we dig, the greater the
risk. The supporting structures of your
394
00:35:03,310 --> 00:35:05,830
shelter have to hold up all that weight
above you.
395
00:35:06,090 --> 00:35:09,310
And if they can't hold that weight, you
get buried alive.
396
00:35:12,610 --> 00:35:14,890
Some accidents will inevitably happen.
397
00:35:15,090 --> 00:35:18,730
But if we're safe and smart about it, we
could build underground cities around
398
00:35:18,730 --> 00:35:19,669
the world.
399
00:35:19,670 --> 00:35:24,750
I think all that is possible. It just
takes a lot of imagination, willpower,
400
00:35:24,750 --> 00:35:25,750
a total commitment.
401
00:35:26,400 --> 00:35:29,040
and technology that I'm not sure exists
today.
402
00:35:30,420 --> 00:35:32,860
But there's a problem we'd have to solve
first.
403
00:35:33,080 --> 00:35:35,200
How can we grow food with no sunlight?
404
00:35:37,800 --> 00:35:44,100
If you have good energy supplies and
enough space underground, you might just
405
00:35:44,100 --> 00:35:48,360
able to engineer conditions in which you
can grow food under artificial
406
00:35:48,360 --> 00:35:49,360
daylight.
407
00:35:49,620 --> 00:35:53,620
As long as I have an ability to
408
00:35:54,320 --> 00:36:00,660
generate the same spectrum of light as
the sun, then I can grow the same crops.
409
00:36:05,000 --> 00:36:08,260
Thankfully, in this scenario, we will
have access to water.
410
00:36:08,600 --> 00:36:12,780
As long as we can mine ice from the
oceans and from the glaciers that form
411
00:36:12,780 --> 00:36:19,620
land. The ice is so fresh that you can
actually melt it and
412
00:36:19,620 --> 00:36:20,558
drink it.
413
00:36:20,560 --> 00:36:26,740
As seawater freezes, the salt actually
gets rejected into the water beneath.
414
00:36:26,840 --> 00:36:31,500
When they go up on an Arctic expedition,
for example, they chop out a chunk of
415
00:36:31,500 --> 00:36:34,520
old sea ice and melt it, and it's fresh
enough to drink.
416
00:36:34,980 --> 00:36:40,020
So underground cities could succeed. We
have energy, shelter, food, water,
417
00:36:40,120 --> 00:36:41,200
everything we need to survive.
418
00:36:41,520 --> 00:36:45,540
And the small remaining population could
thrive, which is good.
419
00:36:45,920 --> 00:36:49,040
Because the surface is transforming into
a bizarre landscape.
420
00:36:49,280 --> 00:36:52,240
It's starting to look like the icy moons
of Jupiter and Saturn.
421
00:37:03,540 --> 00:37:08,200
As the planet continues to move away
from the sun, the surface begins to take
422
00:37:08,200 --> 00:37:09,780
strangely alien features.
423
00:37:10,060 --> 00:37:13,120
If the Earth's orbit were to expand
beyond...
424
00:37:13,760 --> 00:37:15,980
the orbit that is shared by Neptune
today.
425
00:37:16,240 --> 00:37:20,440
At this point, our atmosphere would
begin to rain out and collapse away.
426
00:37:24,580 --> 00:37:27,920
Oxygen and nitrogen make up 99 % of our
atmosphere.
427
00:37:28,280 --> 00:37:33,560
As the global temperature reaches below
a negative 290 degrees Fahrenheit, these
428
00:37:33,560 --> 00:37:38,160
gases will condense to liquid and fall
to Earth in the last precipitation the
429
00:37:38,160 --> 00:37:39,320
planet will ever see.
430
00:37:39,680 --> 00:37:45,080
When the last oxygen and nitrogen flakes
land, That will be it. Our atmosphere
431
00:37:45,080 --> 00:37:46,080
will be gone.
432
00:37:48,160 --> 00:37:54,080
Eventually becoming a giant solid mass
of all of what was once our atmosphere.
433
00:37:55,260 --> 00:37:59,380
At this point, we'd have to seal off our
underground home to prevent our
434
00:37:59,380 --> 00:38:00,580
breathable air from escaping.
435
00:38:00,820 --> 00:38:05,080
But that's only a temporary solution
because we'd soon use up all that
436
00:38:05,240 --> 00:38:08,340
What we'll need to do is to find a long
-term air supply.
437
00:38:10,120 --> 00:38:16,180
If gases like nitrogen and oxygen and
carbon dioxide have frozen as solids on
438
00:38:16,180 --> 00:38:20,700
the surface of our planet, we still need
them as raw materials. We might be able
439
00:38:20,700 --> 00:38:26,520
to go to the surface, harvest this
frozen atmosphere, bring it back with
440
00:38:26,520 --> 00:38:31,220
then thaw it out to make use of the
gaseous compounds it contains.
441
00:38:32,740 --> 00:38:37,080
The main problem here is that our
atmosphere doesn't just provide us with
442
00:38:37,080 --> 00:38:38,080
breathable air.
443
00:38:38,140 --> 00:38:39,820
It's also our defense mechanism.
444
00:38:40,140 --> 00:38:42,740
And without it, the Earth is left
exposed.
445
00:38:49,620 --> 00:38:56,300
When we have objects that fall down on
Earth, like an asteroid
446
00:38:56,300 --> 00:39:02,880
or a meteor, the atmosphere flows that
debris, and it burns it up before most
447
00:39:02,880 --> 00:39:03,880
it can reach the ground.
448
00:39:04,280 --> 00:39:08,860
If we were to lose our atmosphere, then
we lose our shield from all these
449
00:39:08,860 --> 00:39:11,140
things, all these rocks that could come
in from space.
450
00:39:11,460 --> 00:39:16,420
With this protection mechanism gone,
even small meteorites could do a huge
451
00:39:16,420 --> 00:39:17,420
amount of damage.
452
00:39:45,190 --> 00:39:49,270
off into the depths of space, Earth has
become a very different place since the
453
00:39:49,270 --> 00:39:52,650
cold settled in, and the loss of our
atmosphere is devastating.
454
00:39:57,370 --> 00:40:01,630
One of the things that would vanish with
the atmosphere would be the protection
455
00:40:01,630 --> 00:40:05,250
that the atmosphere fords us from space
debris.
456
00:40:06,030 --> 00:40:11,750
All the meteorites, the chunks of ice
from comet's tails, would in fact impact
457
00:40:11,750 --> 00:40:14,290
the Earth. The Earth would look very
pockmarked.
458
00:40:14,510 --> 00:40:18,730
perhaps like the moon, would further be
a dangerous plague.
459
00:40:29,870 --> 00:40:33,910
Without the atmosphere to protect them,
the G -domes on the surface will become
460
00:40:33,910 --> 00:40:34,910
vulnerable.
461
00:40:36,470 --> 00:40:40,130
Eventually, those living above ground
will feel the full wrath of the cold.
462
00:40:57,560 --> 00:41:01,340
Ultimately, without an atmosphere to
protect life on the surface of the
463
00:41:01,480 --> 00:41:04,100
anything trying to survive there is at
risk.
464
00:41:05,560 --> 00:41:09,420
Despite our best efforts, we really
can't expect to survive on the surface.
465
00:41:13,160 --> 00:41:17,260
But remember, inside the Earth, we'll
still have heat and energy for billions
466
00:41:17,260 --> 00:41:21,340
years. And where there's energy, there
can be life, including any human
467
00:41:21,340 --> 00:41:23,360
civilization that's thriving
underground.
468
00:41:27,560 --> 00:41:29,880
What would the future hold for humans?
469
00:41:30,180 --> 00:41:31,440
We've moved underground.
470
00:41:31,680 --> 00:41:36,080
We're living off geothermal energy. And
we're living off our incredible ability
471
00:41:36,080 --> 00:41:37,080
to innovate.
472
00:41:39,980 --> 00:41:44,260
As long as we can maintain an atmosphere
underground and provide our survivors
473
00:41:44,260 --> 00:41:49,960
with oxygen, mankind has a chance to
live on. For people who have lived above
474
00:41:49,960 --> 00:41:53,340
ground, they're not going to be seeing
the sun anymore.
475
00:41:53,740 --> 00:41:56,220
They're not going to feel the wind on
their faces.
476
00:41:56,600 --> 00:41:59,700
They're not going to be able to look up
at the stars at night, not be able to
477
00:41:59,700 --> 00:42:00,700
see the moon.
478
00:42:01,000 --> 00:42:05,760
All these things that we take for
granted make us feel comfortable as
479
00:42:05,760 --> 00:42:06,760
beings.
480
00:42:07,120 --> 00:42:12,420
But if they survive and they have
children, and this goes on for
481
00:42:12,620 --> 00:42:19,040
someone who is born in this underground
environment, for them, that will be all
482
00:42:19,040 --> 00:42:20,340
that they ever knew.
483
00:42:20,620 --> 00:42:23,780
They won't miss what they didn't know in
the first place.
484
00:42:27,280 --> 00:42:31,700
One of the things that's most beautiful
about the way life survives on Earth is
485
00:42:31,700 --> 00:42:33,840
that it is incredibly adaptable.
486
00:42:35,160 --> 00:42:41,260
It finds the tiniest bit of energy and
thrives in some of the most inhospitable
487
00:42:41,260 --> 00:42:42,260
environments.
488
00:42:43,500 --> 00:42:48,540
So the odds are, since our planet is
full of life, and we have a hard time
489
00:42:48,540 --> 00:42:53,620
finding any place that doesn't have any
life on it, that life would continue on.
490
00:42:54,160 --> 00:42:58,240
I think to a lot of people this would
sound like science fiction, but that
491
00:42:58,240 --> 00:43:04,380
back to both the optimism and my thought
that the ingenuity of humanity
492
00:43:04,380 --> 00:43:10,300
being able to bring it back to where we
want it to be. I think that without a
493
00:43:10,300 --> 00:43:14,600
doubt in my mind, given enough time, we
can do it.
494
00:43:16,420 --> 00:43:23,000
It's possible that the pressure of
trying to survive in this extreme and
495
00:43:23,000 --> 00:43:27,880
environment, would actually help us come
up with new ways to exist in the
496
00:43:27,880 --> 00:43:28,880
universe.
497
00:43:30,820 --> 00:43:34,080
Conceivably, even new ways to retake our
planet.
498
00:43:35,920 --> 00:43:41,780
Perhaps we could find a way to engineer
our whole world into something not the
499
00:43:41,780 --> 00:43:44,240
same as it was, but new.
500
00:43:45,940 --> 00:43:49,700
A new world that we could then claim
again as ours.
