程度副詞

how the universe works at the very basic level,

我們可以發現的最基本的層次。

想試著了解某樣東西 是如何運作的，

what you're actually doing is you're looking for

我稱之為「隱藏結構」的東西。

For example, you take something like your cell phone,

如果我們用你的手機作為例子，

這會讓保固無效，但不是個大問題。

is that it's made of tiny little electronic components.

它是由許多小型電子元件組成。

And those electronic components are actually moving around

and that's where the name "electronics" comes from.

你就可以製作你自己的 智慧型手機

or you could make various other electronic devices as well.

who, actually for a living, try and do this sort of thing

not just for, say, a cell phone or its components,

但不僅僅侷限於手機或它的元件，

but asking what, say, your hand is made of,

而是想了解── 比方說你的手、

And so, using various kinds of instruments

we've been able to probe deeper and deeper over the years,

經年累月下來 我們已經可以探測得更為深入，

and we now know that the matter that we're made of

is actually made of tiny little elementary particles.

實際上是由 極微小的基本粒子組成。

And elementary particles interact with each other

that those forces of nature themselves actually operate

by exchanging elementary particles as well.

竟然也是藉由 交換粒子來運作。

They're actually particles of force that are exchanged

就是大型強子對撞機， 或稱 LHC，

and give them the masses that we observe.

讓它們具有我們觀測到的質量。

因此，這幅令人振奮的圖像 就像是

to the one I showed you for the cell phone.

我先前給你看的 關於手機的那些。

and we have the rules of particle theory,

而我們有粒子理論的基本規則，

各式各樣的東西， 並讓它運作。

Now, we actually think that we've only just

scratched the surface of finding this quantum world,

So, what I did is I gathered the particles up

into the patterns that they tend to form,

but we don't know where those patterns come from.

但我們不知道這些模式是怎麼來的。

but we don't know where the patterns come from.

但是我們並不知道模式是從哪裡來的。

Also, we now know that there's a huge amount

than just the things that I was just talking about.

我前面所說的各種物質都還多。

and experiment with it and figure out what it is.

並做實驗來了解它到底是什麼。

And then, the other thing I'd like to talk about

這可能是我們最熟悉的作用力，

according to those rules of particle theory.

So, given that gravity is actually about the shape

所以，假設重力就像是 愛因斯坦所教導我們的那樣，

we, in working out what the quantum story of gravity is,

我們想探索量子世界中的重力， 我們稱為量子重力，

we hope to get to groups of questions like,

我們想要了解一些問題，像是：

are there particles of space and time itself
