宇宙中最先进的文明

The Most Advanced Civilization In The Universe

Earth and civilization, as we know it, has come a long way in the past 200,000 years
地球文明 在过去的20万年里已经走过了很长的一段路
and has experienced a multitude of changes in that time.
并且在那段时期里经历过无数次变化
The human species has only existed for 0.0015% of the immense 13.7 billion-year age of the universe.
人类存在的时间仅占宇宙年龄——137亿年的0.0015%
However, humanity has conquered some of the most daunting tasks in that time period.
然而 人类却在这极短的时间里成功挑战了一些极其困难的任务
They’ve come from hunting and gathering in the fields of Africa
他们通过在非洲捕猎和农耕
to colonizing the entire planet in a time period
在极短的时间内遍布整个星球
that is relatively a blink of an eye on the cosmic level.
这在宇宙角度上看相当于一眨眼的时间
Some of the greatest minds ever exist have helped push modern civilization forward,
过去 一些伟人推进了现代文明的发展
and achieve goals that were once thought to be impossible.
并达成了曾经被认为是不可能实现的目标
And just the past 150 years,
并且就在过去的150年
we have gone from being stuck to the Earth’s soil
我们成功地摆脱了地球的束缚
to landing on our closest cosmic neighbor, the moon.
抵达了离我们最近的邻居 月球
Humanity’s success is nothing short of spectacular,
人类成就对我们而言十分伟大
but on the universal scale we may be rather insignificant.
但当这些被放到宇宙层面上时 又显得无关紧要
What would happen if we met an advanced alien species
当我们遇见先进的外星生物 并且其有着
with technology more advanced than we could ever imagine?
比我们想象中更先进的技术时 会发生什么呢?
In 1964, a Soviet astronomer by the name of Nikolai Kardashev
1964年 苏联天文学家尼古拉·卡尔达肖夫
introduced the hypothetical scale
提出了一个假说
that can be used to measure a potential civilization’s level of technological advancement
来量度文明层次及先进程度
based on the amount of energy this civilization can produce.
基于一个文明所能够利用的能源量级
And it’s known today as the “Kardashev Scale”.
在今天被称为“卡尔达肖夫指数”
The scale has three traditional types
这个假说有三个经典类型
but many extensions and modifications to the scale have been proposed since its creation.
但它被提出之后 很多扩展模型也被提了出来
The scale is logarithmic,
这个假说是对数的
meaning as we go on
意味着我们的文明
the amount of power to the civilization has is much, much more substantial.
所拥有的能量量级更大
In 1964, Kardashev defined the three base levels of civilization
1964年 卡尔达肖夫提出定义文明的三个层次
based on the power available to them.
根据各个文明使用能源功率数量的量级
Type Ⅰ the smallest of the original types
Ⅰ型 原始模型中最小的层次
is also called a “planetary civilization”.
也被称为“星球文明”
This is no similar to our good old friend earth
这和我们的老朋友地球并不一样
Type Ⅰ civilizations are capable of storing and using all of the energy
Ⅰ型文明有能力储存并使用从主恒星
which reaches this planet from its host star
抵达星球上的所有能量
which in our case is the sun.
对我们而言主恒星就是太阳
This amount of energy would amount to an enormous 7×10^17 watts.
能源量级能达到7×10^17瓦特
Notice how I said most similar though,
为什么我说大部分情况下都是符合的
as their modern civilization here on earth,
是因为地球上的现代文明
it’s not quite exactly fit into the Type Ⅰ civilization category.
并不准确地在Ⅰ型文明的范畴内
Yes I know, we pathetic humans can’t even fit into the lowest level of the advanced civilization.
是的 我知道 我们可怜的人类甚至不能达到先进文明的最低等级
Rather than fitting into a type Ⅰ civilization,
比起符合Ⅰ类文明
we humans lie in one of the extended types of civilizations.
我们人类所属的是另一额外的文明类型
Type 0.
0型
You see when this scale was proposed,
当这个假说被提出时
famous astronomer Nashville physicist Carl Sagan produced a formula
纳什维尔著名天文学家 物理学家卡尔·萨根提出了一个公式
to define a certain hypothetical civilization’s Kardashev rating.
来确定一个已知文明的卡尔达肖夫指数
This is that formula.
这就是那个公式
While “K” represents a hypothetical civilization’s Kardashev rating.
字母“K”代表一个假定文明的卡尔达肖夫指数
While P represents the amount of power the civilization uses in watts.
字母“P”代表这个文明能利用的能量的瓦数
A proposed Type 0 civilization will control approximately 1 megawatt
被提出的0型文明能控制大约1兆瓦特能量
or 1 million watts of power
或者说一百万瓦特能量
which is miniscule compared to the amount of power we use on a daily basis.
比我们日常需求的能量量级还要更小
In 2015 alone
仅在2015年这一年
the total world energy consumption 17.35 terawatts
整个世界的能量消耗量是17.35兆兆瓦
or this huge number.
或者说17,350,000,000,000瓦特
Plugging this number into P and cranking out the numbers,
将这个数代入字母“P”中然后得到
our Kardashev rating as a civilization will be approximately that Type 0.72.
我们文明的卡尔达肖夫指数近似于0.72型文明
Even as a civilization with seven billion humans on our planet
尽管我们是拥有着七百万人口在星球上的文明
12 of which adventured to the moon
其中的12个人到了月球上冒险
with spacecraft sent billions of miles into the abyss of interstellar space
通过乘坐太空舱被送进百万米以外的星际空间的深渊之中
and plans to colonize Mars in the near future.
并且还计划在未来征服火星
We still only score a measly 0.72 of the Kardashev Scale.
我们仍然只是卑微的0.72型文明
According to Carl Sagan
根据卡尔·萨根所说
“Humanity is going through a phase of technical adolescence
“人类正在经历一个技术青春期
Typical of a civilization about to integrate the type 1 Kardashev Scale.”
文明类型正在向Ⅰ型文明过渡“
Michio Kaku,
加来道雄
another brilliant theoretical physicist,
另一个杰出的理论物理学家
suggests that humans may attain Type Ⅰ status in the next 100–200 years,
认为人类将会在未来100—200年内进入Ⅰ型文明
Type Ⅱ status in perhaps next few thousand years,
几千年后可能会进入Ⅱ型文明
and type Ⅲ status in 100,000 to 1 million years.
而在十万年至一百万年期间会进入Ⅲ型文明
This really goes to show the truly immense time skills
这的确会消耗大量的时间
it would take to advance to the next type of civilization.
去过渡到下一文明类型
However we are heading towards becoming a Type Ⅰ civilization
然而我们正在转变成为Ⅰ型文明
in the next couple hundred years or so.
在未来的几百年将会实现
And this is a huge step for humanity.
并且这对人类发展而言是一大步
As a Type Ⅰ civilization,
作为Ⅰ型文明
we would have complete control over our own planet.
我们将会完全控制我们自己的星球
Perhaps we could influence the weather,
可能我们能够影响天气
change the geological makeup of our own planet
改变我们星球的地貌
and much much more.
等等等等
However even this amount of power is tiny compared to the next type of civilization.
然而这个量级的能量与下一类型文明相比起来仍然很微小
Type Ⅱ.
Ⅱ型文明
A Type Ⅱ civilization,
Ⅱ型文明
also referred to as a “stellar civilization”,
亦称作“一流文明”
can control the total energy of its host star
可以控制主恒星的全部能量
and transfer the energy throughout the entire solar system.
并且可以在整个太阳系中传输能量
One popular hypothesized device to use to harness the entire energy output
一个十分流行 用于提取Ⅱ型文明
of a type Ⅱ civilization’s host star are called “Dyson structures”.
主恒星能量的装置叫做“戴森球”
You may have seen these before as they are rather popular in science fiction.
你可能早已见过这些 因为它们在科幻小说中更加流行
The name was coined by Freeman Dyson
它的名字取于弗里曼·戴森
and it is essentially a system of orbiting solar power satellites.
它本质上是环绕太阳的壳状轨道结构
Basically it’s an insanely massive hollow sphere
主要是在一个文明的主恒星周围
built around a civilization’s host star
构建起一个巨大的中空的球体
to milk all of the energy from it.
来从主恒星提取能量
That first made a great video on this idea
根据这个假设绘出了一个视频
and you should definitely check it out.
你可以清晰地看出
I’ll be sure to leave a link to it in the description.
我一定会在简介中留下视频链接
But back on topic,
但是回到主题
another rather exotic idea to harness energy for a Type Ⅱ civilization
另一个不同的Ⅱ型文明统治能量的方式
would be to feed a stellar mass,
是去增加恒星质量
for example, a star,
例如 一颗恒星
into a nearby black hole and collect the photons emitted by the accretion disc.
进入黑洞里面并且通过冲击层吸收发散出来的光子
Now how a civilization could somehow deposit a star into a black hole is beyond me?
一个文明如何将恒星存储在离我很远的黑洞里呢?
What is it the means of energy nonetheless?
能量的去向又是哪呢?
A type Ⅱ civilization would not only build these supermassive structures
Ⅱ型文明不仅会构建这些特大质量的建筑
but would control and live within them.
还会控制它们 依赖它们生存
They would control every single planet in their solar system,
他们能够控制太阳系中的每一个行星
mile the asteroids at their leisure,
并且在空闲的时候摆弄小行星
and essentially do whatever they want inside the solar neighborhood.
并可以在太阳系范围内做他们任何想做的事
The amount of power the civilization would have is remarkable
Ⅱ类文明所拥有的能力是非凡的
what is nothing when compared to a Type Ⅲ civilization.
但是与Ⅲ类文明相比又微不足道
Type Ⅲ civilization also referred to as a “galactic civilization”
Ⅲ类文明亦被称为“银河文明”
can control the total energy of its entire host galaxy.
可以控制主银河系的全部能量
The amount of power the civilization would have is truly frightening
Ⅲ型文明所拥有的能量量级十分令人恐惧
and it’s already in the realm of science fiction
它已经是在科幻小说的范围内了
but I’ll cover it anyway.
但我还是会讲一下
You see this civilization would function extremely similar to
Ⅲ型文明与Ⅱ型文明的
the way a Type Ⅱ civilization work.
运转方式相似
It would harness the power of stars
它会统治恒星
mind planets and asteroids and so on,
行星 小行星等等
but not only for one star,
但不仅仅是一颗恒星
but for billions of stars.
而是数十亿颗恒星
A civilization such as this would use planets and solar systems like legos
一个像这样的文明会将行星和太阳系当作乐高一样
building and deconstructing planets to build up their empire elsewhere in the galaxy.
解构他们并在银河系的某一处建造起自己的帝国
The galaxy would seemingly become their playground
银河系将会变成他们的游乐场
and everything they do and use is merely a toy.
他们所做的和所用的都只不过是玩具
Harnessing the energy of quasars would be like hitting the lottery for them.
对于他们而言 统治类星体的能量就像是中彩票一样
The supermassive black hole the center of their galaxy
银河的中心——特大质量的黑洞
could be used as an energy source for a Type Ⅲ civilization.
可以被Ⅲ型文明当作能量资源利用
Galactic real-estate would become a reality with planets, stars,
银河房地产可能会变成现实 当一些至高领导人
or even complete solar systems being auctioned off by some supreme leader.
将行星 恒星 甚至是整个太阳系拍卖掉的时候
Interestingly enough
很有趣的是
this hypothetical galaxy may not even be noticeable.
这个假设的银河系甚至可能不值得注意
If such a civilization did exist,
如果确实存在这样的文明
all of the energy from these stars would be held and used for whatever the civilization may need.
那么只要这个文明需要 随时都能从这些恒星上提取和利用能量
This means all the star light, gas and element
这意味着在星系中所有的星光 气体 和元素
in an entire galaxy would become like your kitchen pantry.
都会成为你的厨房食品储藏室
If all of the matter and their entire galaxy was exploded for energy
如果所有的东西和整个银河系都被用来开发能源
an outside observer would view the galaxy to be completely invisible.
从外部看银河系将会变得完全不可见
It would appear as if there were a hole in the galaxy
如果银河系中有洞的话它甚至会消失
or if they have colonized the entire galaxy perhaps nothing at all.
或者可能他们统治了一个什么也没有的银河系
There is a place in space known as “the great void”.
在宇宙中有一个地方叫做“大空洞”
At nearly 330 million lightyears in diameter
直径大约是3.3亿光年
the great void is one of the largest known voids in the entire universe
在整个宇宙中 大空洞是最大的已知空洞之一
and is commonly referred to as a “supervoid”.
它亦被称为“超级空洞”
This region of space is seemingly devoid of life and galaxies as we know it.
这个空间与我们所知道的一样缺乏生命和星系
A region of space with such a massive size as the great void contained.
一个与大空洞一样巨大的空间
Scientists estimate there should be at least 2,000 galaxies in spiral space.
科学家们估计至少有2000个星系在螺旋空间里
But today,
但至今为止
they’ve only met 60 galaxies that have been discovered in the great void.
在这个广阔的空间里只有60个星系被发现
This is a mere 3% of the amounts of galaxies that should occupy an area this large.
只有3%的星系跟它一样大
So where are they?
所以它们在哪呢?
Could be Type Ⅲ civilizations completely dominating an entire region of space,
可能是Ⅲ型文明彻底统治了整个宇宙
milking a 330 million-lightyear wide region for resources?
将3.3亿光年宽的范围内的资源榨干?
