It's gonna make power transformers explode all across the country.
磁暴将引发整个国家的变压器爆♥炸♥
When the transformers go,
变压器瘫痪后
every piece of electrical equipment in America goes with it.
美国的每一处电力设备也全都会瘫痪
It's a critical infrastructure,
电力系统起着决定性作用
probably the keystone infrastructure.
是所有基础设施的基石
If you take electric supply away,
如果供电被中断
virtually all other infrastructures
几乎其他所有的基础设施
will fail either immediately or within just a few days.
都会立刻失效或在几天内失效
Where does your drinking water come from?
饮用水从何而来
It needs electricity in a lot of cases to pump the water up.
供水的许多环节都需要电才能抽起水来
So you're not gonna have drinking water.
否则就喝不到饮用水
You're not gonna have lights unless you have your own generator.
没有自己的发电机也不会有灯光
And then when the generator runs out of fuel,
即使有当发电机燃料耗尽时
well, if you run down to the gas station
你就得跑去加油站
to get some more fuel for the generator,
弄些发电机的燃料
There's no electricity to run the pumps.
可是没有电油泵无法运行
The electricity will not come back on,
电力一去不复返
because the transformers will be too damaged to repair.
因为变压器遭到重创难以修复
They will have to be completely replayed,
必须重建所有的变压器
and that is not a simple proposition.
这可不是什么简单事
It takes at least six months
要从头开始建一座单相变压器
to build a single transformer from scratch.
需要六个月的时间
That means no electricity,
这意味着在六个月内
no water, no fuel, no banking
大城市将陷入
for six months for major cities.
无电无水燃料匮乏金融停滞的状态
Smaller cities will take longer.
而小城市要经历的时间则更长
To rebuild the entire grid might take over a decade.
重建一个完整的电网则需要十年以上的时间
The cost of repair is staggering.
修复费用高得难以置信
The cost in human lives... disturbing.
更令人沉痛的是...那些因此牺牲的生命
There is no way that we could sustain a 300 million population
在这种毁灭性的灾难面前
in this country with large disruption of that scale.
国家无法维持3亿人的生存
Some estimates suggest that a large magnetic storm
一些分♥析♥表明一场强烈的磁暴
could lead to the death of 1/3 to 1/2 of the population
可能会夺去现代世界人口的
of the developed world.
三分之一至二分之一
That's 100 million deaths in the U.S., 250 million in Europe,
也就是1亿美国人 2亿5千万欧洲人
A billion in Asia, lives lost to the power of a magnetic storm.
和10亿亚洲人死于一场磁暴
Up until this time,
直到现在
this sort of disaster has truly been incomprehensible.
我们对这种灾难也没有一个清晰的认识
Can anything be done to prevent this type of destruction?
我们能做些什么阻止这场灾难吗
Experts are trying to plan for that now,
专家们已经开始行动
with better observation of the Sun's explosive magnetic surface,
他们对太阳表面的磁暴进行更细致的观察
as well as designing shields for cables
为电缆设计防护措施
and creating surge preventers for transformers.
并为变压器设立强电振荡防护器
We now have to think in ways of retrofitting design changes
现在我们必须想办法在电网的设计上
into those grids.
做一些改进
We're still at early days of trying to figure out
对于如何加强这些设施的防护
how to harden the infrastructures against these.
我们仍处于起步阶段
The apocalyptic power of a magnetic storm reveals
磁暴无与伦比的威力揭示了
just how essential magnetism is in our lives,
磁是多么普遍而深远地影响了我们的生活
and in the very universe itself.
乃至整个宇宙
Electromagnetism is the most important thing
电磁是如此重要
that you can see that's driving our daily lives.
你会发现它驾驭着我们的日常生活
I think people don't think about magnetism
我想人们不会在意磁现象
because it's kind of like a fish in water doesn't think about water.
就像水里的鱼不会在意水一样
It's everywhere. It holds everything together.
它无处不在聚合世间万物
It holds the atmosphere, the action of breathing,
大气因磁而生呼吸因磁而发
the action of seeing is an electromagnetic interaction.
眼睛看见事物的过程是一种电磁交互
Magnetism is a simple force,
磁力是一种简单的力
one of four most basic forces in the universe.
是宇宙中四种最基本的力之一
It can become a child's toy,
它可以成为孩童的玩具
it holds our molecules together, and if we're lucky,
让我们的分子聚集在一起幸运的话
it protects our planet from the vast powers of the Sun.
它能使我们幸免于太阳放射的巨大能量
To the inhabitants of Earth,
对于地球上的居民来说
it is one of the most overlooked forces in our universe.
它是宇宙间最被我们忽视的力之一
Yet magnetism gives and can take everything.
然而一切都任其主宰
