宇宙时空之旅：未知世界（2020）

Cosmos: Possible Worlds S01E10

Part 5 Aug. 24, 2022, 10:55 a.m.

The volcano became utterly calm.
空气凉爽清新
The air was cool and fresh.
海面如玻璃般澄澈
And the sea like glass.
培雷火山在1902年5月8日
When Mount Pelée erupted at 8:02 AM on
上午8点02分喷发爆♥炸♥声非常响
May 8th, 1902, the explosion produced a sound so loud
连在五百英里外的委内瑞拉都听得见
it was heard 500 miles away, in Venezuela.
大量火山碎屑物冲了下来
The massive pyroclastic flood,
致命的过热气体积聚成云
a death cloud of super-heated gasses,
在数分钟内越过山谷笼罩全市
crossed the valleys to the city in minutes.
其爆♥炸♥力等同于
The explosion was the equivalent of just one
一颗战略核弹
strategic nuclear warhead.
火山喷发后三天
Three days after the eruption,
住在岛上另一区的人们
men from the other part of the island,
来到仍然在冒烟的圣皮埃尔市街道巡视
combed the still smoking streets of Saint Pierre.
帮忙收尸
To collect the bodies and burn what the volcano had failed
和处理未被火山完全烧尽的残骸
to consume completely.
很少有人熬得过
Few have ever experienced what
路易·奥古斯特·希尔巴里经历的事
Louis-Auguste Cyparis endured and lived to tell.
火山喷发时他听见狱卒短暂的惨叫声
When the volcano erupted, he heard the screams of his
之后就陷入可怕的静默
captors briefly before a terrifying silence.
接着一道猛烈高温
And then, a fierce heat came blasting through the
冲进牢房♥的小通气孔
tiny vent in his cell.
他不断跳脚想要避开
He hopped and jumped around to avoid it,
但肩膀以下依旧严重烧伤
but was still severely burned up to his shoulders.
他痛苦地忍♥受了三天
For three days he suffered in agony with
除了牢房♥墙面的水汽无以为继
no other sustenance than the moisture on the walls of his cell.
被关在铜墙铁壁的独居地牢
His sentence to solitary confinement in the thick
反而救了他一命
walled dungeon had saved his life.
他是圣皮埃尔市三万居民中
He was one of only two survivors of the
仅有的两名幸存者之一
30,000 citizens of Saint Pierre.
那我们呢？
What about us?
我们会知道何时该拉响警报吗？
Would we know when to sound the alarm?
我们能预见将要到来的灾难吗？
Can we see what's coming?
我们能及时清醒吗？
Can we awaken in time?
我们回来追踪其中一个原子
We're back on the trail of one of our two atoms.
铀原子
The uranium atom.
铀原子天生不稳定
A uranium atom is inherently unstable.
迟早会衰变
Sooner or later, it decays.
其原子核内的一个粒子射出
A particle from its nucleus breaks away,
铀原子就会
transforming the uranium atom
变成完全不同的元素
into an entirely different element.
钍
Thorium.
我们正飞越放射性衰变的交叉火力
We're flying through the crossfire of radioactive decay.
原子内的粒子像子弹一样
Subatomic particles move like bullets through the
在生命体的精细结构间移♥动♥
fine structure of life.
从分子间分离出电子
Shearing electrons from their molecules.
这就是游离辐射能影响生命体的原因
This is how ionizing radiation affects living things.
那些染色体不可能躲过
Those chromosomes never had a chance.
所以核武器才比传统武器危险许多
This is why atomic weapons are so much more dangerous than conventional ones.
我们身边甚至体内都有游离辐射
Ionizing radiation is all around us and even inside us.
少量的游离辐射并不会带来威胁
At low levels, it poses no threat.
如果是大量那就另当别论了
But at higher levels, it's a different story.
在短期内若暴露在致命的辐射量中
In the near term, exposure to lethal levels of radiation can
会让细胞发生失控反应
cause a runaway reaction of the cell that makes it
癌症的发生几率会以指数倍增加
multiply exponentially. Cancer.
而它带来的带来的伤害也会影响后世
But its power to harm can also echo down the corridors of time.
当放射线照进蝴蝶(生殖细胞)的染色体
When the radiation tore into the chromosomes of the
凡走过必留下痕迹
butterfly, it left a trail of destruction in its wake that
会让蝴蝶未出生后代的命运就此改变
changed the destiny of the butterfly's unborn offspring.
它的基因突变了
A mutation in its genes.
我们和蝴蝶有很多共同点
We have a lot in common with butterflies.
基因结构的任何改变
Any change in the DNA architecture will be copied
都会复♥制♥到往后的世世代代
over and over again in succeeding generations.
损害会一直传递下去
The damage is passed on.
摧残我们的未来
Vandalizing our future.
我们是原子构成的
We are made of atoms that were born in stars thousands of
它形成于数十亿年以前的数千光年外的太空
light years away in space and billions of years ago in time.
为了追寻起源
The search for our own origins has carried us
我们偏离了自我世界的纪♥元♥
far from our epoch in our world.
我们都是星尘
We are star-stuff,
与宇宙其他部分有着紧密连接
deeply connected with the rest of the universe.
构成我们的物质生于宇宙之火
The matter we are made of was generated in cosmic fire.
现在我们经过千万年错综复杂的排列组合
And now, we, ambulatory collections of seven billion
7乘以10的27次方个原子组成的移♥动♥集♥合♥
billion billion atoms intricately assembled over
已经发现了一个方法
eons has devised a means to tap that cosmic fire,
开♥发♥藏在物质中心的宇宙之火
hidden in the heart of matter.
我们无法抛弃这一知识
We cannot unlearn this knowledge.
而且不幸的是人类是愚蠢疯狂的
And tragically, insanity runs in our family.
自从几名科学家的信开启这个梦魇之后
The letters that the scientists wrote to begin
之后还有一封信
this nightmare were followed by another.
这封信是写给地球的
This one, a letter to the planet,
声明这项物理学新发现
stating that this new understanding of physics
需要用新的方式去思考
demanded a new way of thinking.
*出自1955年发表的《罗素-爱因斯坦宣言》
宣言对核武器带来的危险深表忧虑
并呼吁各国领导人通过和平方式解决国际冲突
"我们因为一言不合就要选择死亡吗？"
"Shall we choose death because we cannot forget our quarrels,
"恳请人类回归初衷"
we appeal as human beings to human beings.
"谨记人性忘怀得失"
Remember your humanity and forget the rest."
我们的另一个原子呢？
And what of our other atom?
碳原子？
The carbon atom?
就在你们之中
It's inside one of you.
