终于把前言听完了~耶~

下面就是正文喽~加油~

PART I LOST IN THE COSMOS

第一部分 迷失在宇宙


They’re all in the same plane. They’re all going around in the same
direction. . . . It’s perfect, 
you know. It’s gorgeous. It’s almost uncanny.

-Astronomer Geoffrey Marcy describing the solar system

它们都处于同一平面。 它们都在沿同一方向转动...... 你要知道,这真是完美无缺的, 这真是不可思议的,这几乎是很神奇的。 

--天文学家杰弗里•马西对太阳系的描述


1 HOW TO BUILD A UNIVERSE 
一 如何营造一个宇宙


NO MATTER HOW hard you try you will never be able to
grasp just how tiny, how spatially unassuming(在空间上不耗费的), is a proton. It is just way too small. 

无论怎么努力,你都永远也想像不出质子有多么微小,占有多么小的空间。它实在太小了。


A proton is an infinitesimal part of an atom, which is itself of course an insubstantial thing. Protons are so small that a little
dib of ink like the dot on this i can hold something in the region of 500 billion of them,
rather more than the number of seconds contained in half a million years.
So protons are exceedingly
microscopic, to say the very least.
 

质子是原子极其微小的组成部分,而原子本身当然也小不可言。质子小到什么程度?像字母"i"上的点这样大小的一墨水,就可以拥有约5000亿个质子,说得更确切一点,要比组成1.5万年的秒数还多。因此,起码可以说,质子是极其微小的。


Now imagine if you can (and of course you can’t)
shrinking one of those protons down to a billionth of its normal size into a space so small that it would make a proton look enormous. Now pack into that tiny, tiny space about an ounce of
matter. Excellent. You are ready to start a universe. 

现在,请你想像一下,假如你能(你当然不能)把一个质子缩小到它正常大小的十亿分之一,放进一个极小的空间,使它显得很大,然后,你把大约30克物质装进那个极小极小的空间。很好,你已作好创建一个宇宙的准备。


I’m assuming of course that you wish to build an
inflationary universe.
If you'd prefer instead to build a more old-fashioned, standard Big Bang universe, you'll need additional materials.
In fact, you will need to gather up everything there is every last
mote and(前:尘埃,斑点. 注意连读) particle of matter between here and the edge of creation and squeeze it into a
spot so infinitesimally compact that it has no dimensions at all. It is known as a
singularity

我当然估计到,你希望创建一个会膨胀的宇宙。不过,要是你愿意创建一个比较老式而又标准的大爆炸型宇宙,你还需要别的材料。事实上,你需要收集现有的一切东西--从现在到宇宙创建之时的每个粒子--把它塞进一个根本谈不上大小的极小地方。这就是所谓的奇点
