And today, after briefly describing what they found,

而今天，在簡短的描述他們的發現之後，

I'm going to tell you about a highly controversial framework

我將告訴你們一個可以解釋他們的發現，

the Milky Way and other distant galaxies,

超出銀河系和一切遙遠的星系以上，

而只是一個極度龐大的宇宙群，

Now the idea of a multiverse is a strange one.

I mean, most of us were raised to believe

我們大多數人在成長中都被教予

that the word "universe" means everything.

“宇宙”這個詞代表著所有的一切。

我說“我們大多數”是經過考慮的，

as my four-year-old daughter has heard me speak of these ideas since she was born.

因為我的四歲的女兒從出生便開始聽我說這些想法，

I love you more than anything in the universe."

我愛你超過宇宙中所有的一切。”

然後她轉過來對我說， “爸爸，

But barring such an anomalous upbringing,

most with fundamentally different features,

它們或許有著從根本上完全不同的特徵，

that would rightly be called universes of their own.

that there's reason for taking it seriously,

I'm going to tell the story of the multiverse in three parts.

我將把多元宇宙的故事分成三部份。

I'm going to describe those Nobel Prize-winning results

我將描述那獲得諾貝爾獎的研究結果，

我將為那個謎團提出一個解釋。

It's based on an approach called string theory,

它基於一個叫做弦理論的方法，

and that's where the idea of the multiverse

I'm going to describe a cosmological theory

which will pull all the pieces of the story together.

而它將把故事所有的片段聯繫在一起。

好的。 第一部份從1929年開始。

establishing that space itself is stretching,

The prevailing wisdom was that on the largest of scales

當時普遍的認知是，在最大的範圍內，

there was one thing that everyone was certain of:

有一件事情是所有人都確信的：

That, much as the gravitational pull of the Earth

slows the ascent of an apple tossed upward,

將往上拋的蘋果的速度慢下來，

how the expansion rate has changed over time.

宇宙隨著時間過去，擴張速度的變化

They found that the expansion is not slowing down.

他們發現擴張并沒有緩緩減速。

Instead they found that it's speeding up,

如果你看到一個蘋果那樣表現的話，

are surely well-deserving of the Nobel Prize,

但它們也提起了一個相似的問題。
