Scientists just invented
an entirely new way
of observing the universe,
and it's not with light,
because what we've detected
is waves in actual space.
That is, the stretching
and compression of space
itself in a ripple
passing by us.
And as soon as we
turn on the detector,
we saw the merge
of two black holes.
Scientists have been dreaming
of this for a long time.
Einstein first proposed his
theory of general relativity
over 100 years ago, stating
that gravity is really
just the curvature of space
and time, or spacetime.
In other words, a
huge mass like a star
curves space and time like
this ball placed on a sheet.
And if mass could bend space,
then accelerating or moving
masses could send out
ripples in the sheet,
and we call those
gravitational waves.
Einstein came up
with all the math
to describe this
over 100 years ago.
Then, nearly 75 years
later in 1992, scientists
founded LIGO, the Laser
Interferometer Gravitational

科學家剛發明了一個全新的方法
去觀察宇宙，但不是以光
因為我們已經偵測到的是空間中實際的波
也就是空間的拉伸跟壓縮
產生的漣漪穿過我們
而只要啟動偵測器
我們看到兩個黑洞的融合
科學家夢想已久
愛因斯坦早在一百年前第一次發表相對論
陳述重力只是
空間和時間的曲率，或是時空
換句話說，像是星球巨大的質量
扭曲空間和時間，像是放一顆球在床單上
如果時間可以彎曲空間
那麼加速或是移動的質量可以在床單上送出漣漪
而我們稱之重力波
一百年前愛因斯坦以數學提出來描述重力波
一百年前愛因斯坦以數學提出來描述重力波
然後，近來75年至1992
科學家成立LIGO，雷射干涉重力波天文台

English: 
Wave Observatory, to
search for these waves.
But it wasn't until 2015
that gravitational waves
were finally detected
from the event where
two black holes about 30
times the mass of the sun
collided, sending out
shock waves that reached us
1.3 billion years later.
The technology had to come so
far for this to be possible.
Check it out.
In the LIGO detector, you've
got two vacuum tunnel arms
with lasers that go back
and forth reflecting off
of mirrors on the other end.
Depending on the
distance those laser
beams travel after
reflecting off the mirrors,
when they meet back up
again you get interference,
like waves that interfere
in water making patterns.
If space is
stretched or squeezed
in one of these directions by
passing gravitational waves,
the laser beams in that arm will
travel for more or less time,
affecting how the
two beams interfere
when they meet back up.
And we can tell space
has been stretched.
But this detector has
to be so sensitive,
it's affected by quantum
mechanical vibrations
in the mirrors.

Chinese: 
以研究這些波
但是直到2015年重力波才終於被偵測到
來自遙遠的事件
兩個三時被太陽質量的黑洞碰撞
在130萬年後送出衝擊波給我們
在130萬年後送出衝擊波給我們
科技直到最近才可以觀察到
來看一下
在LIGO偵測器內有兩個真空長臂
雷射在裡面前後反射
於終端的鏡子
隨著雷射經過反射行走的距離改變
隨著雷射經過反射行走的距離改變
當它們回來並相遇會得到干涉
像水波干涉產生圖樣
如果空間被拉長或擠壓
其中一個沿著重力波傳播的方向
雷射光傳播需要更多或更少時間
影響干涉圖案
當他們回程碰頭時
那我們可以知道空間曾被拉長了
但是這偵測器太靈敏了
受鏡子上量子力學的振動影響
甚至受鏡子上量子力學的振動影響

Chinese: 
因為太靈敏，他會得到附近卡車開過的震動
因為太靈敏，他會得到附近卡車開過的震動
但是科學家找到切掉雜訊的方法
除此之外，還有兩個實驗室
一個在路易斯安那，一個在華盛頓
確定信號不是來自當地
兩個偵測訊號完美的符合時
就是令人起雞皮疙瘩的時候
當科學家知道聽到了正確的信號
科學家用聽這個動詞
我想是將這個科技與過去的科技
通常是光學做一個區分
但是波通常不發出聲音
因為聲音不在太空中傳播
但是科學家得到了波型
並將它轉成聲波
使這個低語讓全世界聽到
但是這個低語影響我們的方法不是馬上那麼明顯
但是這個低語影響我們的方法不是馬上那麼明顯
我是說，就像你比較少關注生物學或人類學
比較容易看出重要性或令人振奮
在發現了第一個人類骷髏
或是終於排序整個人類的基因組
因為它開啟了大門

English: 
So sensitive, it was
picking up vibrations
from trucks driving
on roads nearby.
But scientists found ways
to cut out that noise.
And in addition, there are
two labs, one in Louisiana
and one in Washington,
making sure
that the signal detected
wasn't from something local.
That moment when those two
detections matched up perfectly
was the goosebumps moment
when scientists realized
we had heard a true signal.
Scientists have been
using the term "heard",
which I think helps set
the technology apart
from anything we've ever
done, usually with light.
But the waves don't
actually make a sound,
because sound doesn't
travel through empty space.
But scientists did
take the waveform
and turn it into
a sound waveform
to make the chirp
heard 'round the world.
But the way this chirp
affects us is not
immediately obvious to all.
I mean, as little as you might
follow biology or anthropology,
it's easier to see the
importance or excitement
in finding the first
hominid skeleton,
or finally sequencing
the entire human genome,
because it opens doors.

Chinese: 
重力波的觀測其本身很令人興奮
但是這些波假設已經穿播宇宙
早在人類存在以前
而且我們從來無法得知
就像你整個人生是聾的
最終可以第一次聽到
那就是我們對重力的認知
那就是我們在天文學上做的
然後我們可以用這全新的比喻性的透鏡來觀察宇宙
在極度猛烈的事件上
以及我們了解不多的物體，像是黑洞
再加上，這科技是發展史上最精確的工具
再加上，這科技是發展史上最精確的工具
它促使了冷凍劑、光學進步
以及對數個領域有貢獻
還有，誰能忘記雖然愛因斯坦諷刺地
對相對論的應用不感興趣
我們重度依賴它產生數百萬鎂的GPS相關工業
我們重度依賴它產生數百萬鎂的GPS相關工業
最後，因為它事關重大
我要甚至要冒險的去說
這很酷
如果物理不再有任何實用的應用

English: 
The observation of gravitational
waves in and of itself
is exciting, but these
waves have hypothetically
been passing through
the universe since way
before humans existed and
we've never known for sure.
It's like being deaf your entire
life and finally able to hear
for the first time.
That's what we've
done for gravity.
That's what we've done for
the field of astronomy.
And we can look out at the
universe with an entirely new
metaphorical lens, and at
extreme violent events,
and at objects that we know very
little about, like black holes.
Plus, the technology is
the most precise instrument
ever developed.
It's improved cryogenics,
optics, and made contributions
to a number of other fields.
And who can forget that,
though Einstein was ironically
uninterested in the applications
of his theory of relativity,
we rely very heavily on it
for the multi-billion dollar
industry surrounding GPS.
And lastly, I'm going
to venture so far
as to say that we should
care because it's relevant.
It's just cool.
If physics no longer had
any practical applications,

Chinese: 
我們可能還會持續研究因為我們好奇
我們想知道世界更多
這是宇宙如何運作
同樣的宇宙運行的方式可能是
你我存在的方式
我們生存的時空是一幅美景
只要我們創造新的方式去了解它
謝謝你妳收看這集的物理女孩
有個愉快的物理
 

English: 
we'd probably still keep doing
it because we are curious.
We want to know about our world.
This is how the universe
works, the same universe that
works in such a way
that it's possible
for you and me to exist.
Spacetime is the landscape
in which we live,
and we've just created a
new way to understand it.
Thank you for watching this
episode of "Physics Girl",
and happy physicsing.
