我想要邀請你們
00:14
to come along on a visit
1
2611
1706
一起去參觀
00:16
to a dark continent.
2
4341
1389
一個黑暗的大陸。
00:18
It is the continent hidden
3
6399
1614
它是一個隱藏在
00:20
under the surface of the earth.
4
8037
2052
地表之下的大陸。
00:22
It is largely unexplored,
5
10113
2293
它還未被探索、
00:24
poorly understood,
and the stuff of legends.
and the stuff of legends.
6
12430
2683
未被理解， 充斥著許多傳說。
00:27
But it is made also of dramatic landscapes
7
15137
2838
但它有壯觀的地形，
00:29
like this huge underground chamber,
8
17999
2495
例如這個巨大的地下洞穴，
00:32
and it is rich with surprising
biological and mineralogical worlds.
biological and mineralogical worlds.
9
20518
4841
和豐富神奇的生物、礦物世界。
00:38
Thanks to the efforts of intrepid voyagers
in the last three centuries --
in the last three centuries --
10
26149
4826
感謝無畏的航行者
在過去三個世紀的努力，
在過去三個世紀的努力，
00:42
actually, we know also thanks
to satellite technology, of course --
to satellite technology, of course --
11
30999
3834
當然，也要感謝衛星技術，
00:46
we know almost every single square meter
of our planet's surface.
of our planet's surface.
12
34857
4204
我們才能對地球表面瞭若指掌。
00:51
However, we know still very little
about what is hidden inside the earth.
about what is hidden inside the earth.
13
39085
4941
然而，我們仍對地球的
內部世界知之甚少，
內部世界知之甚少，
00:56
Because a cave landscape,
like this deep shaft in Italy, is hidden,
like this deep shaft in Italy, is hidden,
14
44050
5925
因為洞穴很隱密，
例如這座在義大利的深井，
例如這座在義大利的深井，
01:01
the potential of cave exploration --
the geographical dimension --
the geographical dimension --
15
49999
3354
我們對洞穴探險和地理屬性
01:05
is poorly understood and unappreciated.
16
53377
2368
知之甚少，經驗也不多，
01:07
Because we are creatures
living on the surface,
living on the surface,
17
55769
3035
因為我們是住在地球表面的生物，
01:10
our perception of the inner
side of the planet
side of the planet
18
58828
4147
我們對地球內部的認知不確實。
01:14
is in some ways skewed,
19
62999
1964
01:16
as is that of the depth of the oceans
20
64987
2452
如同我們對海洋
01:19
or of the upper atmosphere.
21
67463
2507
或是大氣的理解，一樣不清楚。
01:23
However, since systematic cave exploration
started about one century ago,
started about one century ago,
22
71094
6958
但是由於我們在一個世紀之前
就對洞穴開始了系統性探索，
就對洞穴開始了系統性探索，
01:30
we know actually that caves exist
in every continent of the world.
in every continent of the world.
23
78076
4371
所以我們知道其實
世界各大洲都有洞穴。
世界各大洲都有洞穴。
01:34
A single cave system,
like Mammoth Cave, which is in Kentucky,
like Mammoth Cave, which is in Kentucky,
24
82471
4044
如美國肯塔基州的猛獁洞，
01:38
can be as long
as more than 600 kilometers.
as more than 600 kilometers.
25
86539
3984
一個洞穴系統就可長達
超過 600 公里。
超過 600 公里。
01:43
And an abyss like Krubera Voronya,
which is in the Caucasus region,
which is in the Caucasus region,
26
91270
4107
至於世界上已知的最深洞穴，
01:47
actually the deepest cave
explored in the world,
explored in the world,
27
95401
2778
高加索地區的庫魯伯亞拉洞穴，
01:50
can go as far as more than 2,000
meters below the surface.
meters below the surface.
28
98203
4321
這個無底洞可深達
地面下超過 2,000 公尺，
地面下超過 2,000 公尺，
01:54
That means a journey of weeks
for a cave explorer.
for a cave explorer.
29
102548
3721
這代表著洞穴探險家
需要花上數週進行探險。
需要花上數週進行探險。
01:59
Caves form in karstic regions.
30
107545
3226
洞穴會在喀斯特地區形成，
02:02
So karstic regions are areas of the world
31
110795
3180
喀斯特地區是指世上某些地方，
02:05
where the infiltrating water
along cracks, fractures,
along cracks, fractures,
32
113999
3490
裂紋和破裂處的入滲水
02:09
can easily dissolve soluble lithologies,
33
117513
3960
可輕易溶解可溶性岩石，
02:13
forming a drainage system
of tunnels, conduits --
of tunnels, conduits --
34
121497
2780
並形成由地道組成的引流系統。
02:16
a three-dimensional network, actually.
35
124301
2479
其實這就是一個三維網絡。
02:18
Karstic regions cover almost 20 percent
of the continents' surface,
of the continents' surface,
36
126804
5879
喀斯特地區佔各大洲
接近百分之二十的面積。
接近百分之二十的面積。
02:24
and we know actually that speleologists
in the last 50 years
in the last 50 years
37
132707
5124
我們也知道洞穴學者
事實上在過去的五十年間，
事實上在過去的五十年間，
02:29
have explored roughly 30,000 kilometers
of cave passages around the world,
of cave passages around the world,
38
137855
5664
曾在世界各地約三萬公里的
洞穴通道進行探險。
洞穴通道進行探險。
02:35
which is a big number.
39
143543
1368
這是一個很大的探險。
02:36
But geologists have estimated
that what is still missing,
that what is still missing,
40
144935
4499
但地質學家曾估算
有待被發現及測繪的範圍
02:41
to be discovered and mapped,
41
149458
2230
02:43
is something around 10 million kilometers.
42
151712
3551
仍有約一千萬公里。
02:47
That means that for each meter
of a cave that we already know,
of a cave that we already know,
43
155287
3290
這代表著我們已經知道的、
02:50
that we have explored,
44
158601
1533
已經探索的每一公尺洞穴，
02:52
there are still some tens of kilometers
of undiscovered passages.
of undiscovered passages.
45
160158
5394
就有大約幾十公里的
通道尚未被發現。
通道尚未被發現。
02:57
That means that this is really
an endless continent,
an endless continent,
46
165576
2915
這代表著這是一個真正
無盡頭的領域，
無盡頭的領域，
03:00
and we will never be able
to explore it completely.
to explore it completely.
47
168515
3498
我們永遠都不可能完成所有探險。
03:04
And this estimation is made
without considering other types of caves,
without considering other types of caves,
48
172597
3496
這個估算沒有包含
其他類型的洞穴在內，
其他類型的洞穴在內，
03:08
like, for example, inside glaciers
or even volcanic caves,
or even volcanic caves,
49
176117
4439
例如冰川洞穴，
甚至是由熔岩流形成、
甚至是由熔岩流形成、
03:12
which are not karstic,
but are formed by lava flows.
but are formed by lava flows.
50
180580
3532
非喀斯特地貌的火山洞穴。
03:16
And if we have a look at other planets
like, for example, Mars,
like, for example, Mars,
51
184136
5656
如果我們留意其他星球，例如火星，
03:21
you will see that this characteristic
52
189816
1850
你們會發現這個特徵
03:23
is not so specific of our home planet.
53
191690
3087
並非我們星球獨有。
03:27
However, I will show to you now
that we do not need to go to Mars
that we do not need to go to Mars
54
195623
4352
現在我會讓你們看到
即使不到火星去，
即使不到火星去，
03:31
to explore alien worlds.
55
199999
2205
我們也能夠探索外星世界。
03:35
I'm a speleologist, that means
a cave explorer.
a cave explorer.
56
203750
3940
我是洞穴學者，也就是洞穴探險家。
03:39
And I started with this passion
when I was really young
when I was really young
57
207714
3908
我從年輕時就熱愛
03:43
in the mountains not far
from my hometown in North Italy,
from my hometown in North Italy,
58
211646
4061
探索離我家不遠、位於義大利北部
03:47
in the karstic regions of the Alps
and the Dolomites.
and the Dolomites.
59
215731
3497
阿爾卑斯山脈及多洛米蒂山脈的
喀斯特地區洞穴。
喀斯特地區洞穴。
03:51
But soon, the quest for exploration
brought me to the farthest corner
brought me to the farthest corner
60
219252
3841
但過了不久，
持續的探索帶領我到
持續的探索帶領我到
地球最遠的角落，
03:55
of the planet, searching
for new potential entrances
for new potential entrances
61
223117
2729
找尋可能通往這尚未
被發現的領域入口。
被發現的領域入口。
03:57
of this undiscovered continent.
62
225870
1903
04:00
And in 2009, I had the opportunity
to visit the tepui table mountains,
to visit the tepui table mountains,
63
228578
5061
2009 年，我有機會到訪
位於奧利諾科及亞馬遜盆地的
平頂山地形山脈。
平頂山地形山脈。
04:05
which are in the Orinoco
and Amazon basins.
and Amazon basins.
64
233663
2996
04:08
These massifs enchanted me
from the first time I saw them.
from the first time I saw them.
65
236683
4552
從第一次見到這些平頂山地塊，
我就為之著迷。
我就為之著迷。
04:13
They are surrounded by vertical,
vertiginous rock walls
vertiginous rock walls
66
241259
3367
它們被垂直、
令人暈眩的岩壁所包圍，
令人暈眩的岩壁所包圍，
04:16
with silvery waterfalls
that are lost in the forest.
that are lost in the forest.
67
244650
3471
還有沒入森林的銀色瀑布。
04:20
They really inspired in me
a sense of wilderness,
a sense of wilderness,
68
248145
3332
它們有著遠超於數百萬年的靈魂，
04:23
with a soul older than millions
and millions of years.
and millions of years.
69
251501
3298
那份荒蕪感啟發了我。
04:27
And this dramatic landscape
inspired among other things
inspired among other things
70
255480
3911
這戲劇性的地貌
同時也啟發了許多其他事物，
同時也啟發了許多其他事物，
04:31
also Conan Doyle's
"The Lost World" novel in 1912.
"The Lost World" novel in 1912.
71
259415
4560
例如柯南・道爾在 1912 年
所著的小說《失落的世界》。
所著的小說《失落的世界》。
04:35
And they are, really, a lost world.
72
263999
3304
它們也的確是一個失落的世界。
04:41
Scientists consider those mountains
as islands in time,
as islands in time,
73
269001
5285
科學家認為以前這些山脈為島嶼，
04:46
being separated
from the surrounding lowlands
from the surrounding lowlands
74
274310
2638
在千百萬年前
04:48
since tens of millions of years ago.
75
276972
2684
從周邊低地中分離出來。
04:51
They are surrounded
by up to 1,000-meter-high walls,
by up to 1,000-meter-high walls,
76
279680
3901
它們被可高達一千公尺的岩壁包圍，
04:55
resembling a fortress,
impregnable by humans.
impregnable by humans.
77
283605
3132
就像人類無法攻破的堡壘。
04:58
And, in fact, only a few
of these mountains have been climbed
of these mountains have been climbed
78
286761
3214
而事實上，人類只曾攀登
05:01
and explored on their top.
79
289999
1836
或探索少數的山頂。
05:04
These mountains contain also
a scientific paradox:
a scientific paradox:
80
292740
2869
這些山脈也有著一個科學悖論：
05:07
They are made by quartz,
81
295633
2060
它們由石英形成，
05:09
which is a very common mineral
on the earth's crust,
on the earth's crust,
82
297717
3167
石英是地殼很常見的礦物質。
05:12
and the rock made up by quartz
is called quartzite,
is called quartzite,
83
300908
4378
而由石英形成的岩石被稱為石英岩，
05:17
and quartzite is one of the hardest
and least soluble minerals on earth.
and least soluble minerals on earth.
84
305310
5308
是地球上最堅硬、
最難溶解的礦物質之一，
最難溶解的礦物質之一，
05:22
So we do not expect at all
to find a cave there.
to find a cave there.
85
310642
3391
所以我們從沒想過能在
那裡找到洞穴。
那裡找到洞穴。
05:26
Despite this, in the last 10 years,
speleologists from Italy,
speleologists from Italy,
86
314057
4918
然而，在過去的十年中，
來自義大利、斯洛伐克、捷克
以及委內瑞拉和巴西的洞穴學者，
以及委內瑞拉和巴西的洞穴學者，
05:30
Slovakia, Czech Republic,
and, of course, Venezuela and Brazil,
and, of course, Venezuela and Brazil,
87
318999
3805
05:34
have explored several caves in this area.
88
322828
2979
曾探索這個地區的數個洞穴。
05:37
So how can it be possible?
89
325831
2487
這怎麼可能呢？
05:40
To understand this contradiction,
we have to consider the time factor,
we have to consider the time factor,
90
328342
4061
為了理解這矛盾之處，
我們必須考慮時間因素。
我們必須考慮時間因素。
05:44
because the history of the tepuis
is extremely long,
is extremely long,
91
332427
3303
由於平頂山的歷史相當久遠，
05:47
starting about 1.6 billion years ago
with the formation of the rock,
with the formation of the rock,
92
335754
4657
約十六億年前岩石開始形成，
05:52
and then evolving with the uplift
of the region 150 million years ago,
of the region 150 million years ago,
93
340435
6540
然後在一億五千年前，
這個地域繼盤古超大陸瓦解
這個地域繼盤古超大陸瓦解
05:58
after the disruption
of the Pangaea supercontinent
of the Pangaea supercontinent
94
346999
2976
形成大西洋後，
06:01
and the opening of the Atlantic Ocean.
95
349999
2353
開始上升，逐漸演變。
06:04
So you can imagine that the water had tens
or even hundreds of millions of years
or even hundreds of millions of years
96
352376
6310
因此，你可以想像
流水有著億萬年的時間
流水有著億萬年的時間
06:10
to sculpt the strangest forms
on the tepuis' surfaces,
on the tepuis' surfaces,
97
358710
4058
在平頂山表面塑造出奇怪的形狀，
06:14
but also to open the fractures
and form stone cities, rock cities,
and form stone cities, rock cities,
98
362792
6014
也開啟了破裂處形成
石頭城市、岩石城市，
石頭城市、岩石城市，
06:20
fields of towers which are characterized
in the famous landscape of the tepuis.
in the famous landscape of the tepuis.
99
368830
5521
即平頂山地貌特有的塔型岩柱。
06:26
But nobody could have imagined
100
374375
1444
但任誰也無法想像，
06:27
what was happening inside a mountain
in so long a time frame.
in so long a time frame.
101
375843
4736
在這麼長的時間，
一座山裡到底發生了什麼事。
一座山裡到底發生了什麼事。
06:32
And so I was focusing in 2010
on one of those massifs,
on one of those massifs,
102
380603
4477
在 2010 年，
我專注於其中一座平頂山地塊，
我專注於其中一座平頂山地塊，
06:37
the Auyán-tepui, which is very famous
because it hosts Angel Falls,
because it hosts Angel Falls,
103
385104
3851
奧揚特普伊山。
由於有著世界上最高、
由於有著世界上最高、
06:40
which is the highest
waterfall in the world --
waterfall in the world --
104
388979
2589
垂直高達約 979 米的
安赫爾（天使）瀑布，
安赫爾（天使）瀑布，
06:43
about 979 meters of vertical drop.
105
391592
4059
這座山因而非常有名。
06:47
And I was searching for hints
of the existence of cave systems
of the existence of cave systems
106
395675
4886
而我則透過衛星圖像
06:52
through satellite images,
107
400585
1868
尋找洞穴存在的痕跡，
06:54
and finally we identified an area
of collapses of the surface --
of collapses of the surface --
108
402477
4690
終於找到了一處下陷的地面，
06:59
so, big boulders, rock piles --
109
407191
2246
有碩大的礫石和巖堆，
07:01
and that means that there
was a void below.
was a void below.
110
409461
3311
代表下方是空的。
07:04
It was a clear indication that there
was something inside the mountain.
was something inside the mountain.
111
412796
3949
這明確指出，那山裡有些甚麼。
07:08
So we did several attempts
to reach this area,
to reach this area,
112
416769
4846
於是我們好幾次
嘗試以陸路搭配直升機
嘗試以陸路搭配直升機
07:13
by land and with a helicopter,
113
421639
1762
接近此處，
07:15
but it was really difficult
because -- you have to imagine
because -- you have to imagine
114
423425
3550
但這相當困難，因為你要知道，
07:18
that these mountains are covered
by clouds most of the year, by fog.
by clouds most of the year, by fog.
115
426999
4379
這些山脈長年被雲霧所遮蓋。
07:23
There are strong winds,
116
431402
1373
強風以及每年接近
4,000 公釐的降雨量，
4,000 公釐的降雨量，
07:24
and there are almost 4,000 millimeters
of rainfall per year,
of rainfall per year,
117
432799
4582
07:29
so it's really, really difficult
to find good conditions.
to find good conditions.
118
437405
3262
讓我們難以碰到好天氣接近山脈。
07:32
And only in 2013 we finally
landed on the spot
landed on the spot
119
440691
4783
只有到了 2013 年，
我們終於在一處著陸，
我們終於在一處著陸，
07:37
and we started
the exploration of the cave.
the exploration of the cave.
120
445498
2494
並開始對洞穴進行探索。
07:40
The cave is huge.
121
448723
1917
那洞穴非常大。
07:42
It's a huge network under the surface
of the tepui plateau,
of the tepui plateau,
122
450664
3827
那是平頂高原下的巨型網絡。
07:46
and in only ten days of expedition,
123
454515
3694
而在僅僅十天的考察，
07:50
we explored more than 20 kilometers
of cave passages.
of cave passages.
124
458233
4123
我們探索了超過
20 公里的洞穴通道。
20 公里的洞穴通道。
07:54
And it's a huge network
of underground rivers,
of underground rivers,
125
462380
5397
那是一個由地下河流、
07:59
channels, big rooms,
extremely deep shafts.
extremely deep shafts.
126
467801
5174
渠道、大洞廳和極深的豎坑
組成的巨型網絡。
組成的巨型網絡。
08:04
So it's really an incredible place.
127
472999
3024
那真的是一個不可思議的地方。
08:08
And we named it Imawarì Yeuta.
128
476047
2541
我們把它稱為 "Imawari Yeuta"。
08:10
That means, in the Pemón indigenous
language, "The House of the Gods."
language, "The House of the Gods."
129
478612
6261
在佩蒙土著語中，
意思是「眾神之家」。
意思是「眾神之家」。
08:16
You have to imagine that indigenous people
have never been there.
have never been there.
130
484897
3782
你必須知道，
這些土著從未到過這個地方。
這些土著從未到過這個地方。
08:20
It was impossible for them
to reach this area.
to reach this area.
131
488703
3505
他們不可能接近這個地方。
08:24
However, there were legends
about the existence
about the existence
132
492232
2206
但是，那裡流傳著
08:26
of a cave in the mountain.
133
494462
2027
關於山中洞穴的傳說。
08:28
So when we started the exploration,
134
496513
1770
所以當我們開始探索時，
08:30
we had to explore with a great respect,
135
498307
2230
我們需要心懷極大的尊重。
08:32
both because of the religious beliefs
of the indigenous people,
of the indigenous people,
136
500561
3561
這不單是因為土著的宗教信仰，
08:36
but also because
it was really a sacred place,
it was really a sacred place,
137
504146
2365
更是因為這裡從無人類進入過，
08:38
because no human had entered there before.
138
506535
3335
是一個神聖的地方。
08:41
So we had to use special protocols
139
509894
1803
我們也因此需要根據特別的規則，
08:43
to not contaminate the environment
with our presence,
with our presence,
140
511721
2789
嘗試不讓我們的存在污染環境。
08:46
and we tried also to share
with the community,
with the community,
141
514534
2175
我們亦嘗試與當地社群、
08:48
with the indigenous community,
our discoveries.
our discoveries.
142
516733
2673
土著社群分享我們的發現。
08:51
And the caves represent, really,
a snapshot of the past.
a snapshot of the past.
143
519430
4556
事實上，這些洞穴就是過去的寫照。
08:56
The time needed for their formation
144
524503
2712
它們或許需要長達五千萬年，
08:59
could be as long as 50 or even
100 million years,
100 million years,
145
527239
4924
甚至億萬年的時間形成，
09:04
which makes them possibly the oldest caves
that we can explore on earth.
that we can explore on earth.
146
532187
4901
讓它們成為地球上
可探索的洞穴中最古老的一個。
可探索的洞穴中最古老的一個。
09:10
What you can find there
is really evidence of a lost world.
is really evidence of a lost world.
147
538921
5727
你在這裡能找到的，
就是失落的世界存在的證據。
就是失落的世界存在的證據。
09:17
When you enter a quartzite cave,
148
545301
1987
當你進入一個石英岩洞，
09:19
you have to completely forget
what you know about caves --
what you know about caves --
149
547312
3448
你必須忘掉一切關於洞穴的知識，
09:22
classic limestone caves
or the touristic caves
or the touristic caves
150
550784
2997
例如你在某些地方可到訪的
09:25
that you can visit
in several places in the world.
in several places in the world.
151
553805
2357
典型的石灰岩洞或觀光洞穴。
09:28
Because what seems
a simple stalactite here
a simple stalactite here
152
556186
2925
因為那裡看似普通的鐘乳石，
09:31
is not made by calcium carbonate,
but is made by opal,
but is made by opal,
153
559135
5085
並非由碳酸鈣形成，
而是由蛋白石形成。
而是由蛋白石形成。
09:36
and one of those stalactites can require
tens of millions of years to be formed.
tens of millions of years to be formed.
154
564244
5584
而每個鐘乳石都需要千百萬年形成。
09:42
But you can find even stranger forms,
like these mushrooms of silica
like these mushrooms of silica
155
570685
4077
你還能找到更奇怪的形狀，
例如長在大石頭上的
例如長在大石頭上的
09:46
growing on a boulder.
156
574786
2074
蘑菇狀矽石。
09:48
And you can imagine our talks
when we were exploring the cave.
when we were exploring the cave.
157
576884
3786
你也可以想像一下
我們在探索洞穴期間的談話。
我們在探索洞穴期間的談話。
09:52
We were the first entering
and discovering those unknown things,
and discovering those unknown things,
158
580694
4993
那是我們第一次進入
這個未知的地方，
這個未知的地方，
發現未知的事物，
像是這些巨大的蛋。
像是這些巨大的蛋。
09:57
things like those monster eggs.
159
585711
2838
10:00
And we were a bit scared
because it was all a discovery,
because it was all a discovery,
160
588573
4396
我們有些害怕，
因為這不過是一場探險，
因為這不過是一場探險，
10:04
and we didn't want to find a dinosaur.
161
592993
2083
我們並不想找到恐龍。
10:07
We didn't find a dinosaur.
162
595100
1504
而我們的確也沒找到恐龍。
10:08
(Laughter)
163
596628
1597
（笑聲）
10:10
Anyway, actually, we know
that this kind of formation,
that this kind of formation,
164
598249
3297
其實，經過數次研究，
10:13
after several studies,
165
601570
2533
我們得知是生物
10:16
we know that these kinds of formations
are living organisms.
are living organisms.
166
604127
3225
形成了這些東西。
10:19
They are bacterial colonies using silica
to build mineral structures
to build mineral structures
167
607376
5434
這是細菌菌落利用二氧化矽
做成形似疊層石的礦物結構，
做成形似疊層石的礦物結構，
10:24
resembling stromatolites.
168
612834
1930
10:26
Stromatolites are some of the oldest
forms of life that we can find on earth.
forms of life that we can find on earth.
169
614788
4521
疊層石是地球上最古老的生命之一。
10:31
And here in the tepuis,
170
619333
1803
而有趣的是，
10:33
the interesting thing is that these
bacteria colonies have evolved
bacteria colonies have evolved
171
621160
4683
在平頂山，細菌菌落可以演化成
10:37
in complete isolation
from the external surface,
from the external surface,
172
625867
4229
與外界完全隔離，
10:42
and without being in contact with humans.
173
630120
2624
並與人類毫無接觸的情況。
10:44
They have never been
in contact with humans.
in contact with humans.
174
632768
2597
他們從未接觸過人類。
10:47
So the implications
for science are enormous,
for science are enormous,
175
635389
3067
這帶給科學界的暗示相當重大，
10:50
because here you could find,
for example, microbes
for example, microbes
176
638480
4002
因為你能找到，比如說，在醫學上
10:54
that could be useful to resolve
diseases in medicine,
diseases in medicine,
177
642506
4952
可用於治療疾病的微生物，
10:59
or you could find even a new kind
of material with unknown properties.
of material with unknown properties.
178
647482
3936
或者是有著未知特質的新材料。
11:03
And, in fact, we discovered in the cave
a new mineral structure for science,
a new mineral structure for science,
179
651442
4059
事實上，我們在洞穴中為科學界
發現了一種新的礦物結構，
發現了一種新的礦物結構，
11:07
which is rossiantonite,
a phosphate-sulfate.
a phosphate-sulfate.
180
655525
3007
是一種名為 rossiantonite 的
磷酸鹽—硫酸鹽類。
磷酸鹽—硫酸鹽類。
11:11
So whatever you find in the cave,
even a small cricket,
even a small cricket,
181
659606
4714
不論你在洞穴裡找到什麼，
就算只是一隻蟋蟀，
就算只是一隻蟋蟀，
11:16
has evolved in the dark
in complete isolation.
in complete isolation.
182
664344
3968
也在黑暗和徹底的隔離下
進行了演化。
進行了演化。
11:20
And, really, everything that you can feel
in the cave are real connections
in the cave are real connections
183
668336
4253
而你在洞穴裡感受到的一切，
皆是生物界以及礦物學界的
真實連接。
真實連接。
11:24
between the biological
and the mineralogical world.
and the mineralogical world.
184
672613
3040
11:28
So as we explore this dark continent
185
676544
5816
當我們探索這黑暗的領域，
11:34
and discover its mineralogical
and biological diversity and uniqueness,
and biological diversity and uniqueness,
186
682384
6404
並發現其礦物學與生物學的
多樣性和獨特之處，
多樣性和獨特之處，
11:40
we will find probably clues
about the origin of life on our planet
about the origin of life on our planet
187
688812
4369
我們或許就能得知
我們星球上生命的起源，
我們星球上生命的起源，
11:45
and on the relationship
and evolution of life
and evolution of life
188
693205
2977
和生命進化與
11:48
in relationship with the mineral world.
189
696206
2986
礦物之間的關係。
11:51
What seems only a dark, empty environment
190
699216
3942
它看起來只是一個黑暗空虛的環境，
11:55
could be in reality a chest of wonders
191
703182
2793
但事實上可能充斥著有用資訊的
11:57
full of useful information.
192
705999
2480
奇妙之處。
12:02
With a team of Italian, Venezuelan
and Brazilian speleologists,

和巴西的洞穴學者，
12:09
we will be back soon to Latin America,
195
717214
2068
我們不久將回到拉丁美洲，
12:11
because we want to explore other tepuis
in the farthest areas of the Amazon.
in the farthest areas of the Amazon.
196
719306
5448
因為我們希望探索在亞馬遜
最遠處的其他平頂山地貌。
最遠處的其他平頂山地貌。
12:16
There are still very unknown mountains,
197
724778
3020
世上仍有許多未知的山脈，
12:19
like Marahuaca, which is almost
3,000 meters high above sea level,
3,000 meters high above sea level,
198

12:24
or Aracà, which is in the upper region
of Rio Negro in Brazil.

或是位於巴西內格羅河
上游的阿拉卡山。

12:28
And we suppose that we could find there
even bigger cave systems,
even bigger cave systems,
200
736663
4919
我們預計能夠找到更大的洞穴系統，
12:33
and each one with its own
undiscovered world.

201
741606
4688
而每個洞穴都有著
專屬於它未知的世界。

Francesco, you said we don't need
to go to Mars to find alien life,

法蘭斯高，你說我們不需要到
火星便能找到外星生命。
火星便能找到外星生命。
12:52
and indeed, last time we spoke,
you were in Sardinia
you were in Sardinia
206
760935
2925
的確，上次我們談話時，
你正在撒丁島
你正在撒丁島
12:55
and you were training European astronauts.
207
763884
2243
培訓歐洲的太空人。
12:58
So what do you, a speleologist,
tell and teach to the astronauts?
tell and teach to the astronauts?
208
766151
3474
那麼你身為洞穴學者，
你都向太空人說或教些甚麼呢？
你都向太空人說或教些甚麼呢？
13:01
Francesco Sauro: Yeah, we are --
it's a program of training
it's a program of training
209
769649
2783
法蘭斯高・紹羅：是的，
我們......這是一個在洞穴裡

13:09
So they stay in a cave
for about one week in isolation.
for about one week in isolation.
211
777381
3528
他們會在洞穴過一個星期
與世隔絕的生活。
與世隔絕的生活。
13:12
They have to work together
in a real, real dangerous environment,
in a real, real dangerous environment,
212
780933
3880
他們必須在相當危險的環境中合作。
13:16
and it's a real alien environment for them
because it's unusual.
because it's unusual.
213
784837
3810
這對他們來說的確是一個異世界，
因為它是那麼的不尋常。
因為它是那麼的不尋常。
13:20
It's always dark. They have to do science.
They have a lot of tasks.
They have a lot of tasks.
214
788671
4304
它總是黑暗。他們必須做科學研究。
他們有許多任務要完成。
他們有許多任務要完成。
13:24
And it's very similar to a journey to Mars
215
792999
2532
這與前往火星或國際太空站
13:27
or the International Space Station.
216
795555

13:32
that was in your slide show,
219
800635
1833
其中一張照片。
13:34
and it's just representative
of the other photos --
of the other photos --
220
802492
2389
那是所有照片中最具代表性的一張。
13:36
Weren't those photos amazing? Yeah?
221
804905

13:47
because all of those photos
are from the photographers.
are from the photographers.
225
815319
3773
因為這些照片都是出自那些攝影師。
13:51
BG: You bring, actually, photographers
with you in the expedition.
with you in the expedition.
226
819116
3702
布：你在探險期間，
真的帶著攝影師。
真的帶著攝影師。
13:54
They're professionals,
they're speleologists and photographers.
they're speleologists and photographers.
227
822842
2967
他們是專業人士，
他們是洞穴學者，也是攝影師。
他們是洞穴學者，也是攝影師。
13:57
But when I look at these pictures,
I wonder: there is zero light down there,
I wonder: there is zero light down there,
228
825833
4900
但當我看著這些照片，我很納悶，
地表下沒有任何光線，
看起來卻曝光良好 。
看起來卻曝光良好 。
14:02
and yet they look incredibly well-exposed.
229
830757
2783
14:05
How do you take these pictures?
230
833564
1488
你們怎麼拍下這些照片？
14:07
How do your colleagues,
the photographers, take these pictures?
the photographers, take these pictures?
231
835076
3051
你的同事，這些攝影師，
怎麼拍下這些照片？
怎麼拍下這些照片？
14:10
FS: Yeah. They are working
in a darkroom, basically,
in a darkroom, basically,
232
838151
2491
法：是的，他們基本上
是在黑暗的空間中工作。
是在黑暗的空間中工作。
14:12
so you can open the shutter of the camera
233
840666
2119
因此你能按下相機的快門，
14:14
and use the lights
to paint the environment.
to paint the environment.
234
842809
2418
利用燈光掃描環境。
14:17
BG: So you're basically --
235
845251
1255
布：所以你基本上是.......
14:18
FS: Yes. You can even keep
the shutter open for one minute
the shutter open for one minute
236
846530
2735
法：是的，你甚至可以設定
長達一分鐘的快門，
長達一分鐘的快門，
14:21
and then paint the environment.
237
849289
1524
然後掃描環境。
14:22
The final result is what
you want to achieve.
you want to achieve.
238
850837
2704
最終的成果，就是你想得到的。
14:25
BG: You spray the environment with light
and that's what you get.
and that's what you get.
239
853565
3073

14:28
Maybe we can try this at home
someday, I don't know.
someday, I don't know.
240

ABOUT THE SPEAKER
Francesco Sauro - SpeleologistFrancesco Sauro studies caves and other karst features, and his research takes him places no one has ever been before.
Why you should listen
Italian speleologist Francesco Sauro is fascinated by the tabletop mountains of South America, the tepuis. These plateaus, which tower over the Brazilian and Venezuelan rainforest, hide behind their dramatic landscape a lost world of extensive cave structures. They harbor unique geological and biological features that have evolved in isolation over millennia.
With nearly twenty years of caving experience, Sauro has participated in research in many cave systems all over the world, but keeps coming back to the tepuis, where he has led six expeditions since 2009. He leads also a caves training program for European astronauts.
