Of course if this was a real experiment,
當(dāng)然，如果這是真正的實(shí)驗(yàn)
you wouldn't want to go anywhere near it.
你絕不會(huì)想靠近它
The energy given off even from a star this small would be devastating.
如此小的恒星也足以釋放出毀滅性的能量
Back in the early universe,
追溯到宇宙初期
the same process happened for the first time
同樣的過(guò)程第一次發(fā)生了
on a much, much bigger scale.
只不過(guò)規(guī)模遠(yuǎn)大于此
Gravity compressed the hydrogen gas clouds over millions of years
數(shù)百萬(wàn)年來(lái)，萬(wàn)有引力壓縮氫氣云團(tuán)
until deep in the center,
以至中心深處
the hydrogen became hot enough for fusion to occur.
氫氣達(dá)到足夠使聚變發(fā)生的高溫
The first star burst into light,
伴著耀眼的光芒，第一顆恒星誕生了
pouring its energy into the vast universe,
其能量?jī)A入廣袤的宇宙
a product of the laws of nature
這正是自然法則
and the raw materials left over from the big bang.
和宇宙大爆炸殘留物的產(chǎn)物
It was almost 1,000 times bigger than our own sun
它比太陽(yáng)大了近一千倍

This same process still happens in our sun which is
太陽(yáng)如今正在進(jìn)行同樣的過(guò)程
where we get the energy we need to live.
它提供著我們賴(lài)以生存的能量
But there was still a long way to
但我們今天的一切
go to get from this to where we are today.

You can't build a world like ours
僅用氫氣和氦氣這樣的氣體
from simple gasses such as hydrogen and helium.
無(wú)法構(gòu)建出我們這樣豐富多彩的世界
You need all sorts of other elements.
其他各種元素必不可少
You need elements like oxygen and carbon and iron and many more.
比如氧，碳,鐵等元素
But, we got lucky yet again,
幸運(yùn)又一次降臨
beacuse the very same process that causes the stars to shine
因?yàn)閷?dǎo)致恒星發(fā)光的過(guò)程
also just happens to make materials like oxygen and carbon and iron.
正巧產(chǎn)生了氧氣，碳,鐵等物質(zhì)
Stars simply by accident are giant factories.
意外形成恒星相當(dāng)于大型化學(xué)工廠
