黄昏…
Nightfall…
NETFLIX 纪录片系列
…揭示了我们的星球与宇宙的联♥系♥
reveals our planet's connection
to the universe.
一颗流星
A shooting star.
来自太空深处、坠落到地球上的
Ancient rock from the depths of space…
古老岩石
falling to Earth.
里面是构建了我们的宇宙的化学元素
Inside it are the chemical elements
that built our universe.
无数世代以来
For countless generations,
海龟都在海洋中漫游
sea turtles have roamed the oceans,
在它们所吃的食物中搜集宇宙元素
gathering cosmic elements
in the food they eat.
如同它们数几亿年来所做的那样
And as they've done
for hundreds of millions of years…
每一个新生世代
every new generation
都会循环使用这种同样的星尘
recycles this same stardust…
来产生出下一个世代
to produce the next.
诞生于大爆♥炸♥中
Born in The Big Bang…
并在众多恒星的中心锻造出来的
…and forged in the hearts of stars…
90种化学元素创造了一切
…90 chemical elements
have created everything.
贯穿宇宙的整个历史
Endlessly recycled and reconfigured
被无止境地循环使用和重新配置
throughout the entire history
of the universe.
现在
And now…
使用相同的元素
using the same elements,
每只新生海龟都开始了 一个生命周期
each new turtle begins a life cycle…
从中可以反映出恒星的生命
…that mirrors the lives of the stars.
剧名:元素
在澳大利亚的大堡礁
On Australia's Great Barrier Reef…
发生了一件神奇的事情
…something magical has happened.
在沙子下面埋了50天后
After 50 days beneath the sand,
来自整个宇宙的化学元素创造了生命
chemical elements
from across the cosmos have created life.
它们结合起来形成了下一代的绿海龟
Combining to form the next generation
of green sea turtles.
海龟蛋现在已经耗尽了其对 赋予生命元素的供应
The eggs have now exhausted their supply
of life-giving elements.
今天 小海龟们 将首次品尝到空气的滋味
And today, the baby turtles
will take their first taste of air.
当她的兄弟姐♥妹♥们♥ 争先恐后地设法下水时
And as her brothers and sisters
scramble to make it to the water…
一只雌性的小海龟
a little female…
最后出生了
is last to be born.
为了长成成年海龟
In order to grow to adulthood,
她需要收获来自大洋彼岸的化学元素
she will need to harvest chemical elements
from across the ocean.
这是一段危险的旅程
It's a dangerous journey…
每每会有背弃的事情发生
…with treachery at every turn.
但对于小海龟来说
But for the baby turtles,
海洋的召唤是不可抗拒的
the call of the ocean is irresistible.
如果一窝有100只海龟蛋
From a nest of 100,
有时仅有一只会存活下来
sometimes only one will survive.
有时则一只也活不下来
Sometimes none.
但尽管有风险
But despite the risk,
这只雌性小海龟很清楚 她一定要设法下水
the little female knows
she must make it to the water.
她发现了一处突破口
She spots an opening…
并冒险一试
and takes her chance.
今天
Today…
她是一个幸运儿
she's a lucky one.
这只刚孵化的小海龟一直不停地游 直到她将大堡礁远远地甩在身后
The hatchling won't stop swimming
until she has left the reef far behind.
在安全地躲过了聚集在 沿海浅水区域内的掠食者之后
Safely past the predators
that gather in the shallow coastal waters,
她将消失在开阔海洋的巨大虚空之中
she'll disappear into the great void
of the open ocean…
靠以原子为食来度过自己的幼年期
to spend her childhood feeding on atoms.
原子的起源可以追溯回 宇宙的整个生命过程
Atoms whose origins go back through
the entire life of the cosmos.
一直回溯到我们的宇宙 还处于其幼年期的时候
To the time our universe
was in its infancy.
(大爆♥炸♥)
从一无所有到瞬间膨胀至包罗万象
Expanding from nothing
to everything in an instant.
我们的宇宙诞生于大爆♥炸♥中
Our universe was born in The Big Bang.
起初
At first,
它只不过是一团炽热的浓雾
it was nothing but a hot, dense fog.
但随着它持续膨胀
But as it continued to expand…
浓雾开始冷却
the fog began to cool.
并且在可想象的最微小规模上
And on the tiniest scale imaginable…
令人震惊的事情开始发生
…something astounding began to occur.
从雾中凝结出了最初的原子
The first atoms condensed out of the fog.
氢原子
Atoms of hydrogen.
宇宙中的第一个元素
The very first element in the universe.
而在海洋中
And in the ocean,
幼龟们也在搜寻着这种元素
juvenile turtles are hunting it down.
就在它们从蓝水中浮出
As they emerge from the blue
游到大堡礁附近的浅水中觅食之时
to forage in the shallow waters
of the reef.
这是史黛拉
This is Stella.
是成功脱离海滩 并钻入大海中的幸运儿之一
One of the lucky ones
that made it off the beach
and into the ocean.
她的体重已经是 她的孵化重量的2000多倍
She's already more than 2,000 times
her hatching weight
并且成长得很快
and growing fast.
靠着以她在开阔的海洋中漂流时 所发现的生物为食
Feeding on creatures she's found drifting
in the open ocean,
她得以收获了一种 比其它任何元素都多的元素
she's harvested one element
more than any other.
氢
Hydrogen.
它占了她所吃的食物中 所有原子的一半以上
It makes up more than half
of all the atoms in the food she eats.
而且是所有生物中含量最丰富的元素
And is the most abundant element
in all living things.
从鱼类到
From fish
无脊椎动物
to invertebrates.
海葵和珊瑚
Anemones and coral.
在宇宙的黎明到来时所形成的氢原子
Hydrogen atoms formed
at the dawn of the universe
已经从恒星传递到了行星
have been passed on from star to planet,
从行星传递给了动物
planet to animal…
并从猎物传递给了掠食者
and from prey to predator.
这对于史黛拉意味着
Which means, for Stella,
大堡礁周围的水域充满了危险
the waters around the reef
are full of danger.
对于相同原子垂涎欲滴的虎鲨
Tiger sharks, hungry for the same atoms,
在其成年后一直都会捕猎海龟
hunt sea turtles
throughout their adult lives.
斯黛拉的主要防御手段 是她值得信赖的龟甲
Stella's main defense is her trusty armor.
其骨骼由于含有钙和磷而得到强化
Its bone toughened
with calcium and phosphorus.
这两种元素可以追溯到 我们宇宙生命中的
Elements that date back
to another pivotal moment…
另一个关键时刻
in the life of our universe.
(135亿年前)
在大爆♥炸♥后的头三亿年中
For the first 300 million years
after The Big Bang…
既不存在着行星 也不存在着恒星
there are no planets and no stars.
这是宇宙的黑暗时代
The dark ages of the universe.
隐藏于幽暗之中
Concealed in the gloom,
巨大的氢气卷须在宇宙中纵横交错
vast tendrils
of hydrogen gas crisscross the cosmos.
接下来 令人难以置信的是
And then, incredibly,
随着它们被重力拉到一起
as they were drawn together by gravity…
第一批恒星诞生了
…the first stars were born.
这就是宇宙的黎明
This is the cosmic dawn.
也是光线来临的那一刻
The moment the lights came on.
而在那些最早的恒星的深处
And deep within those first stars…
一种非同寻常的过程开始了
a remarkable process began.
温度和压力变得如此极端
Temperatures and pressures
were so extreme…
以至于产生了新的元素
…that new elements were created.
氢原子被强行聚集在一起产生了氦
Atoms of hydrogen
were forced together to make helium.
在它们融合的同时 能量得到了释放
As they fused, energy was released.
由此造成了一种连锁反应 从中产生出了越来越重的元素
Creating a chain reaction that produced
increasingly heavier elements.
