What I love to get people thinking about
我喜歡引導大家去思考
is that all this had to be built, atom by atom,
這一切都是由一個個原子組合而成
celestial engineering on a spectacular scale.
浩大的太空工程
So what drove this cosmic clock work?
那究竟是什么開啟了宇宙的時鐘呢
I would say it was the force of gravity.
我認為正是萬有引力
The idea of gravity
萬有引力的概念
was worked out by Sir Isaac Newton,
是由艾薩克·牛頓爵士提出
who had the same job as me
早在17世紀
here at Cambridge University, back in the 17th century.
他就在劍橋大學擔任同我相同的職位
It supposedly donned on him when an apple fell on his head.
當一顆蘋果落在他頭上時，他受到了啟示
The apple helped him realize that all effects attract each other.
蘋果讓他意識到了萬物相互吸引
And the greater the mass, the stronger the pull.
而且質量越大啊，引力越強
These apples are attracted to the earth
這些蘋果受到了地球的吸引
and although you can't see it,
盡管你肉眼無法看見
the earth moves very slightly up towards the apples.
但地球也向蘋果的方向輕微移動了
All things come together through the power of gravity.
一切都因為萬有引力的存在而聚集在一起
Gravity was created in the Big Bang
萬有引力早在宇宙大爆炸時期就已產生
and has been at work ever since.
并自那時起一直發揮作用
It's what keeps you, me, and apples stuck to the earth.
是萬有引力使得你，我以及蘋果都能保持在地面
In the early universe,
在早期的宇宙中
gravity had a much bigger role to play.
萬有引力的影響比現在大很多
Right after the Big Bang, the universe was just gas,
大爆炸之后，宇宙僅僅是一片霧氣
almost perfectly spread out throughout space.
在空間中近乎完美地延展開來
Over the next 200 million years,
在接下來的2億年里
gravity began to pull the gas back together
萬有引力開始將霧氣集中起來
to produce the very first structures from which everything else would grow.
產生了萬物演變始于的最初結構
But even this very nearly didn't happen.
但即使是這也不是真實情況
If it weren't for another stroke of cosmic luck,
若不是宇宙幸運地遇到另一件事情
there would be no you, no me, no stars
就根本不會存在你，我,恒星
or planets or anything at all.
行星，以及其他的一切
