如果全世界缺氧5秒钟会发生什么?

What If The World Lost Oxygen For 5 Seconds?

氧气是宇宙中第三大气体
Oxygen is the third most abundant element in the universe,
有了氧气我们才能呼吸
allowing us to breathe,
形成各种物质
construct materials
和做到许多超出你想象的事情
and do a lot more than you might realize.
如果地球缺氧五秒钟将会发生什么?
So what would happen if it disappeared from the Earth for 5 seconds?
让我们首先假设一下大气层氧气在减少
If we first look at the loss of atmospheric oxygen
正如空气中氧气一样
as in oxygen in the air,
你可能不敢再想下去了
you may not want to be traveling.
没有氧气 仅在美国的2.15亿辆
Without oxygen, the internal combustion engines found
机动车的内燃机
in 215 million vehicles in the US alone
将无法将热量转化为驱动活塞所必须的动力
would be unable to turn heat into the work required to push the piston inside.
汽车很可能无法启动
Cars would most likely not start,
即使正在行驶中 也会立马停下来
and if already moving, would stop running immediately.
考虑到全世界每分钟约有100架飞机
Considering that an estimated 100 airplanes
正在起飞或者降落
take off or land every minute,
因此缺氧也会导致一些
the loss of oxygen could also cause some
提早迫降事件
early crash landings all over the world,
也许已经起飞的飞机可以
although airplanes already in the air
在氧气恢复之前安全滑翔一会儿
could probably glide safely until oxygen returned.
但是你会不会窒息而死呢?
But would you suffocate?
氧气的确在细胞生物呼吸作用
Oxygen does play a crucial role
最后几步之一中起重要作用
in one of the last steps of cellular respiration,
但幸运的是我们的身体有备选方案
but luckily our bodies have alternative pathways that
以帮助我们在短暂缺氧时仍能存活一段时间
help us survive when we temporarily lack oxygen.
比如在剧烈运动中
For example, during intense exercise,
肌肉细胞会消耗所有氧气
muscle cells will use up all of their oxygen
然后进入乳酸发酵的过程
and switch to a process called lactic acid fermentation,
它能消耗葡萄糖产生能量
which uses glucose to produce energy.
研究发现缺氧细胞能通过重组自己
Cells lacking oxygen also have been shown to reprogram themselves
改变优先顺序 先制造最需要的蛋白质
to prioritize and make the most necessary proteins first.
总而言之
All in all,
如果你可以屏住呼吸五秒钟
if you can hold your breath for 5 seconds,
那么你就很有可能在大气缺氧的灾难中活下来
then you’ll most likely survive the atmospheric oxygen apocalypse.
但是当我们按照字面意思去理解
But when we take the question literally as in
如果我们完全失去氧原子 将会发生什么
‘ What would happen if we lost the oxygen atom completely?’
把它从水 石英 臭氧等化合物中消除
obliterating it from compounds like water, quartz and ozone,
这样的话结果就会变得更加毁灭性
then the results become more devastating.
如果我们只考虑无生命事物
If we consider non-living things alone,
一旦氧原子消失
then nearly everything in the material world would turn
那么几乎物质世界的任何东西都会变成金属粉尘
into a metallic dust once oxygen is done.
包括大楼 汽车 公路 衣服 家具等
This includes buildings, cars, roads, clothes, furniture and more,
因为我们所有的材料诸如混凝土 木材 玻璃
as all our materials like concrete, wood, glass,
石头 砖头 棉花等
stone, brick and cotton
都包含氧原子 或者由氧基化合物构成
all contain or are made up of an oxygen-based compound.
没有氧原子的联结
Without the oxygen bond,
大部分的这些化合物将会只剩下
many of these compounds would be left with their elements
自由移动的元素并且以最简单的形式存在
unbound and in their simplest form.
当你最爱的商店和财物变为灰尘
And while all your favorite stores and possessions turn to dust,
他们也会同时坍塌陷落到地球核心处
they’ll be simultaneously collapsing into the center of the Earth
燃烧成一片灰烬
to be burned in a fiery oblivion.
由于地壳中含氧元素达46%
As oxygen makes up 46% of the Earth’s crust,
我们脚下的土地也不复存在
the ground beneath us would cease to exist.
覆盖地球表面70%的海洋
The ocean which covers about 70 % of the Earth
也会蒸发成为氢气
would evaporate and become hydrogen gas,
而在五秒后氧气恢复的时候
and upon the return of oxygen 5 seconds later,
氢气和氧气之间的反应将会释放出
the reaction between hydrogen and oxygen would release
大量热量 因为再次生成了水
mass amounts of heat as water is produced again.
世界将终结在我们面前
So, the world would end all around us,
不过不要紧 你可能不会见证这一切
but that’s OK. You probably won’t be around to witness any of this
因为我们所有含水的活细胞
as all our living cells contain water
会像海水一样蒸发成氢气
and will, like the ovean evaporate into space as hydrogen gas.
人类也将化为尘土
The rest of us would be dead dust as well.
氧气和氢气消失后
With oxygen and hydrogen gone,
我们的身体就失去了75%的主要组成物质
we’ve lost 75 % of our elemental makeup,
只剩下一些碳 氮 钙
and only a pile of carbon, nitrogen, calcium,
磷和其他微量元素
phosphorus and other trace elements
在身体中
would be what’s left of our bodies.
没有氧气 你一定会感到不那么如意
Without oxygen, it’s safe to say you wouldn’t feel so good.
感谢各位的观看
Thank you guys so much for watching.
如果你们想要了解灾难类型的故事情节
If you love to hear about apocalypse-type scenarios,
一定要及时关注我们最新节目“旁注”
then make sure to check out our newest podcast called”Sidenote”.
这里是关于人类灭绝
It’s about human extinction,
和世界是否要终结 以及人类是否一起毁灭的讨论
and whether or not the world is ending and taking humanity with it.
我会在简介中贴一个链接
I’ll put a link in the description,
你可以仔细收听
so you can listen to that.
你不用在意我们是否乐观
You can find out whether we are optimistic,
或者不管我们是否认为事情看上去不太妙
or whether or not we think things aren’t looking so good.
