A three story building is about 10 metres tall, six times bigger than you.

一棟三層樓的建築物大約有10公尺高，是你的六倍大。

In the opposite direction, six times smaller than you.

反過來，則是你的六分之一大小。

You get things like a cute squirrel, about 27 centimeters small.

你會得到像可愛的松鼠，大約27公分小。

So the building is just as big relative to you as you are to a squirrel.

所以建築物相對於你，就像你相對於松鼠一樣大。

In fact, you are in the middle of everything in the universe.

事實上，你在宇宙萬物的正中間。

Let's go on a fantastical journey together to the small and the large and see if it's true.

讓我們一起踏上一趟奇幻旅程，探索大小世界，看看是不是真的。

The Rufus hummingbird is around 7 centimeters.

Both of these flyers are 23 times bigger or smaller than you, and both fly intercontinental distances.

這兩架飛行器，一個比你大23倍，一個比你小23倍，而且都能進行跨洲飛行。

The tiny bird migrates between Alaska and Mexico.

這種小鳥會遷徙於阿拉斯加和墨西哥之間。

If the hummingbird were the same size as the jet, it would circle the Earth 85 times every year.

如果這隻蜂鳥跟噴射機一樣大，牠每年會繞地球飛85圈。

Deinoponera, the largest ant in the world, is about 55 times smaller than you.

世界上體型最大的螞蟻 Deinoponera，大約比你小55倍。

Their small colonies have around 100 individuals, but no queens.

牠們的小族群約有100隻個體，但沒有蟻后。

Instead, they ruthlessly compete for status within the nest, which can reach 1.2 meters deep.

取而代之的是，牠們會在巢穴中無情地爭奪地位，巢穴深度可達1.2公尺。

If humans lived like Dinoponera, we'd be building towers of over 25 stories filled with offices and ruthlessly competing for status.

如果人類像 Dinoponera 一樣生活，我們會建造超過25層樓的辦公大樓，並無情地爭奪地位。

The deadliest and most annoying insect in the world is the mosquito.

世界上最致命也最惱人的昆蟲是蚊子。

While on the other end, the Empire State Building is about that much larger than you.

而另一方面，帝國大廈大概就比你大這麼多。

Kind of unimaginable how something this small creates so much devastation for something that big.

真的難以想像，這麼小的東西，竟然能對這麼大的東西造成這麼大的破壞。

We're getting to the borders of human perception now.

我們現在已經觸及人類感知的極限了。

Like coarse grains of sand, about 3 millimeters, 550 times smaller than you.

就像粗糙的沙粒，大約3毫米，比你小550倍。

You can feel their shape and roughness between your fingers.

你可以用手指感覺到牠們的形狀和粗糙度。

And if you focus, see them individually, we mix them into concrete that can hold up the tallest towers ever built.

如果你仔細看，把牠們一個個分開來看，我們會把牠們混入混凝土，支撐起有史以來最高的建築。

Like the 828 meter tall Burj Khalifa that's 500 times larger than you.

就像那座高達828公尺的哈里發塔，比你大500倍。

If you were that tall, people would be as small to you as grains of sand in your hand.

如果你這麼高，人們在你眼中就會像你手中的沙粒一樣小。

Anything smaller or bigger and it becomes hard to grasp.

任何比這個更小或更大的東西，都會變得難以掌握。

A medium sized city like lisbon is about 6,000 times larger than yourself and permeated by a network of highways, roads and alleys.

一個像里斯本這樣中等大小的城市，大約是你的六千倍大，並且被高速公路、道路和巷弄網絡所貫穿。

On the other end, about 6,000 times smaller than you.

另一方面，大約是你的六千分之一。

Are your small arteries permeating your whole body.

Actually, you're in the middle, between your network of blood vessels and the network of a city like Lisbon.

事實上，你正處於中間，介於你的血管網絡和像里斯本這樣的城市網絡之間。

If you think of a city as a living being, you find more and more parallels.

如果你把城市想像成一個生物，你會發現越來越多的相似之處。

A small alley is as small to the city as an arteriole.

小巷子對城市來說，就像小動脈對你一樣小。

Your tiniest capillaries are to you what the pipes bringing water to homes are to lisbon.

你最細的毛細血管對你的意義，就像為里斯本的家家戶戶送水的水管對里斯本一樣。

They are as small to you as as you are to the entire Tokyo metropolitan area, the largest urban area in the world, spanning over 160km.

你對東京都會區來說，就像東京都會區對你一樣小，東京都會區是世界上最大的都會區，範圍超過一百六十公里。

You are so incredibly big, filled with so much complexity, so many different moving parts.

你真的好大，充滿了好多複雜的東西，好多不同的活動部件。

Or are you just a cell in the human civilization's superstructure?

或者你只是人類文明超級結構中的一個細胞？

Germany is around 875km from north to south, and the fourth biggest agricultural exporter in the world.

德國南北長約八百七十五公里，是全球第四大的農業出口國。

Rhizobia is a nitrogen fixing bacteria up to 3 micrometers long.

根瘤菌是一種固氮細菌，長度可達三微米。

And without it, that sort of agricultural production is impossible.

沒有它，那種農業生產是不可能的。

So we have a country and a bacterium depending on each other.

所以我們有一個國家和一個細菌，彼此互相依賴。

And you are in the middle, both being roughly 550,000 times larger or smaller than you.

而你就在中間，兩者都大約是你體型的五十五萬倍或小於你。

It's about 12,700 kilometers in diameter, about 7.7 billion times larger than you.

直徑大約是一萬兩千七百公里，大約是你的七十七億倍。

On the other side of the scale is corny bacterium, as little as 0.3 micrometers across, living on your skin and eyes, along with 100 billion other bacteria, more than 10 times more than there are humans on Earth.

在另一端的是可倫氏菌，小到只有零點三微米寬，住在你的皮膚和眼睛上，還有其他一千億個細菌，比地球上的人類多十倍以上。

Again, you're in the center, right in the middle of something so large that our civilization is a mere scratch on its surface.

再一次，你處於中心，就在一個如此巨大的東西中間，我們的文明只是它表面上的一道刮痕。

And something so small and numerous you never notice its presence, even as it touches you.

還有一個如此微小且數量眾多，你從未注意到它的存在，即使它接觸著你。

From here on out, your brain is braking a bit.

從現在開始，你的大腦會稍微減速。

Four times wider than Earth is Neptune, a cold Blue gas giant, 49,500 km wide.

海王星比地球寬四倍，是一顆寒冷的藍色氣態巨行星，寬四萬九千五百公里。

The largest planet, though, is Jupiter, 140,000 km in diameter.

不過，最大的行星是木星，直徑有 14 萬公里。

A titanic abyss shrouded in terrible winds.

一個被可怕的風籠罩的巨大深淵。

You could drop Earth whole into its depths and it would soon simply vanish.

你可以把整個地球丟進它的深處，它很快就會消失。

On the opposite scale, we find the deadly West Nile virus, 50 nanometers in diameter, or one step down.

在另一個極端，我們發現了致命的西尼羅病毒，直徑 50 奈米，或一個等級的差距。

The spike proteins on a coronavirus that open up cells for its RNA payload.

冠狀病毒上的棘蛋白，能打開細胞讓其 RNA 載荷進入。

They are as small to you as you are to the planet Jupiter.

對你來說，它們的渺小程度，就像你對木星這顆行星一樣。

You are in the middle between gigantic planets and the world of viruses.

你就處於巨大的行星和病毒世界之間。

These tiny things, so deadly, let that sink in.

這些微小的東西，如此致命，好好體會一下。

A tiny virus is taking over and killing lung cells up to 500 times larger than itself, with the help of a tiny protein weapon.

一種微小的病毒正在奪取生命，殺死比自身大 500 倍的肺部細胞，這都歸功於一種微小的蛋白質武器。

That's like you trying to kill a giant the size of The Burj Khalifa with a screwdriver.

這就像你試圖用一把螺絲起子殺死一座像哈里發塔那麼大的巨人。

But the real boss of the solar system is the sun.

但太陽才是太陽系的真正老大。

10 times bigger than Jupiter, a billion times larger than you, Controlling all the planets and and source of all energy that drives life.

比木星大十倍，比你大十億倍，掌控著所有行星，以及驅動生命的所有能量來源。

Clearly the boss of our body is a DNA strand containing all the information making your life possible.

很明顯，我們身體的老大是 DNA 鏈，它包含了讓你的生命成為可能的所有資訊。

You're right in the middle between the most important factors keeping everything alive.

你正處於維持一切生命最重要的因素之間。

From here on, things just kind of stop making sense.

從這裡開始，事情就變得有點說不通了。

But now everything just seems to mean a lot.

The supermassive black hole at the center of our galaxy, Sagittarius A is 14.5 billion times bigger than you.

我們銀河系中心的超大質量黑洞，人馬座 A*，比你大 145 億倍。

A hydrogen atom is 15.5 billion times smaller than you.

But the thing is, we're not even close to being done and it's not impossible to get at least a sense of how these scale.

但重點是，我們還沒講完，而且至少可以想像一下這些尺度有多大。

The solar system is 22 trillion times larger than you.

On the other end of the scale is the wavelength of low energy neutrinos released from fusion reactions in our sun.

另一種尺度是來自我們太陽核融合反應釋放出的低能量中微子的波長。

About 100 trillion of them are passing through you every single, single second like ghosts.

大約有 100 兆個像幽靈一樣，每分每秒都穿過你。

A trillion times smaller than you, basically never hitting any of the particles inside you.

If you moved through the solar system in a straight line, you probably wouldn't hit anything either.

如果你直線穿越太陽系，你大概也不會碰到任何東西。

Although things are beginning to get really weird now.

雖然現在事情開始變得有點奇怪了。

A single proton at the heart of the hydrogen atom is almost exactly 1, quadrillion times smaller than you.

氫原子中心的單一質子，差不多比你小 1 千兆倍。

If the proton were as big as you, the hydrogen atoms would be taller than 12 Mount Everests.

如果質子跟你一樣大，那氫原子就會比 12 座聖母峰還高。

On the other end, we meet something that just breaks human brains.

另一方面，我們遇到了一些東西，它會讓人的腦袋直接當機。

We just have no reference for these distances at all.

我們根本就沒有這些距離的概念。

The distance to the closest star to Earth, Alpha Centauri, is not 1,000,000,000,000 times in the other direction from the tiny proton.

離地球最近的恆星，半人馬座阿爾法星的距離，不是往反方向的質子那邊數一兆倍。
