如果往太阳上泼上一桶水会发生什么?

What Will Happen If A Bucket Of Water Is Poured On The Sun

如果向太阳倒一桶水会怎样?
What will happen if a bucket of water is poured on the Sun?
多年后 太阳会熄灭
Many years from now, the Sun will extinguish.
那我们地球会发生什么?
Then what wil happen to our planet?
答案是纯粹而简单的
The answer to this question is pure and simple :
地球会衰亡
The earth will die.
在痛苦中死亡
And it will die an agonizing death.
不过别担心 我们不会亲睹这一幕
But don’t worry, we will not witness it.
幸或不幸
As fortunately or maybe unfortunately,
人类在此前早已绝迹
the human race will become extinct long before this event.
所以 为什么不试试早点熄灭太阳呢?
So, why not try extinguishing the Sun sooner?
假如向太阳倒一大桶水会怎样?
What will happen if we pour a huge bucket of water on it?
通常而言 什么可以熄灭太阳呢?
Generally speaking, what can extinguish the Sun?
如果我们将每日到达地球的光贮藏起来
If we tank all the sunlight that reaches this planet everyday,
就会拥有相当于一百七十万亿瓦的能量
we will have the energy equivalent to 170 trillion kilowatts.
让人类延续千年
This energy will keep humanity going for thousands of years.
但这无法和太阳发散出去的能量相提并论
But this is nothing compared to the energy dispersed by the Sun
毕竟有20亿倍的差距
which is 2 billion times as much energy.
能量向哪儿传播了? 进入外层空间了!
Where is it dispersed? Into outer space.
想象一下 假如人类能吸蓄所有的这些能量
Just imagine, if people could accumulate all this energy,
它的日常量会保证我们上百年无忧的生活
its daily amount will guarantee us millions of years of carefree life.
即使现在 如果我们能专注捕获太阳能
Even now, if we focused on trapping solar energy,
我们也能将付电费抛之脑后
we could forget about paying our utility bills.
但让我们回到现实
But let’s get back to reality.
根据相对论理论
According to relativity theory,
如果一个物体放出能量 质量就会随之减小
if a body gives off energy, its mass diminishes.
因此 太阳就像跑步机上的跑者
Thus the Sun like a runner on a treadmill,
每瞬都在减少质量
is losing its mass by the second,
粗略估计一秒减少4百万吨
roughly 4 million tons a second.
简言之 太阳因燃烧而消亡
In a nutshell, the Sun is extinguishing because it is burning.
或者准确地来说 太阳经核聚变产能
Or speaking more accurately, it produces energy through thermonuclear fusion.
假如太阳与地球的质量相同
If the Sun had the mass of the earth,
就会在5万年后燃尽
it would burn out in 50,000 years.
但这仅仅是另一种假设
But this is just another if.
事实上
Well, as a matter of fact,
太阳的质量差不多是地球的35万倍
the mass of the Sun is nearly 350,000 times that of the earth.
因此 (即使)一天烧掉1730亿吨
Therefore, burning 173 billion tons a day,
也可以燃烧100亿年
it can burn for 10 billion years.
太阳寿命早已过半
With half of this lifespan being already over,
我们的后代会有另一个50亿年的时间来想出对策
our descendants will have another 5 billion years to come up with a plan
阻止这场可怖之灾
on how to prevent this frightful Cataclysm.
有朝一日 太阳会耗尽氢燃料并消亡
Someday the sun will run out of hydrogen fuel and fade away.
但我们不会看到那样的场景
But we won’t be there to see the spectacle.
这需要长久等待
It’s too much waiting.
所以 我忽然想到
So it crossed my mind that
考虑把一桶水倒在太阳上的可能性挺有趣的
would be interesting to consider the possibility of pouring a bucket of water on the Sun.
换句话说 提前把它熄灭
In another words, to extinguish it ahead of time.
首先 找到一个大小合适的桶并非易事
Firstly, it would not be an easy task to find a bucket of appropriate size,
可行性很低
hardly feasible if at all.
但是 让我们假设我们有这样一个桶甚至发现了可以直输到太阳的方法
However, let’s assume we’ve got the bucket and have even discovered a way to deliver it straight to the sun.
接下来会发生什么?
What will happen next?
一个天体物理学家用特殊的软件给出了精确答案
An accurate answer to this question can be given by an astrophysicist with special software.
因为这样的事几乎或从来不会在大自然发生
Since nothing like that has ever happened in nature and hardly ever will.
一般来说物体在地球上燃烧时
Normaly when something burns on earth,
需要有氧化过程的三组份
it burns through combustion which requires three components,
燃料 空气 和热
fuel, air and heat.
如果往燃烧的物体上倒水
If we pour water on burning objects,
在燃料顶部会形成水衣 进而灭火
it extinguishes the fire by forming a coat of water on top of the fuel.
但条件不同的是 太空中没有空气
But what is different about space conditions is that there is no air there.
水不能阻止太阳里的热核反应
Water can’t stop thermonuclear reactions in the Sun.
无论用多少水
No matter how much water we take,
只要太阳的聚变反应持续 太阳就不会熄灭
the Sun will not be extinguished as long as its fusion reactions continue.
简言之 太阳可以烧水
In short, the Sun can burn water.
所以即使倒上一大桶水
So even if we pour a gigantic bucket of water on it,
太阳也只会变得更坚硬 亮6倍
the star will only get harder and six times brighter.
水中含有89%的氧气 而太阳密度约为水的1. 5倍
Water contains 89% oxygen and the Sun’s density is about 1.5 times that of water.
因此 等体积的水会有0.71倍于太阳的质量
Therefore, the volume of water that equals the volume of the Sun will have point seven one times the mass of the Sun.
那会孕育一个2倍重于现在太阳的新星
That will result in the the birth of a new star with the weight two times that of present Sun.
内含48%的氢
And composed of 48% hydrogen,
14%氦和37%的氧气
14% helium and 37% oxygen.
即使我们有可能向太阳倒一大桶水
Even if we had the possibility to pour a huge bucket of water on the Sun,
幸也不幸 我们也无法看到太阳熄灭
fortunately or maybe unfortunately, we wouldn’t be able to see it extinguished.
无论如何 见证比太阳大的新星诞生是一种存疑的乐趣
Anyhow, watching the birth of a new star bigger than the Sun is a doubtful pleasure.
你认为呢?
