What is extraordinary from our point of view is how well it turned out for us. 从我们的角度来看，令人不可思议的是，这个结果对我们来说是那么完美。

If the universe had formed just a tiny bit differently 只要宇宙的形式稍稍不同

if gravity were fractionally stronger or weaker, if the expansion had proceeded just a little more slowly or swiftly 只要引力稍稍强一点或弱一点，只要膨胀稍稍慢一点或快一点

then there might never have been stable elements to make you and me and the ground we stand on. 那么，也许就永远不会有稳定的元素来制造你和我，制造我们脚底下的地面。

Had gravity been a trifle stronger, the universe itself might have collapsed¹ like a badly erected² tent, 只要引力稍稍强一点，宇宙本身会像个没有支好的帐篷那样塌下来，

without precisely³ the right values to give it the right dimensions and density⁴ and component⁵ parts. 也就没有恰到好处的值来赋予自己必要的大小、密度和组成部分。

Had it been weaker, however, nothing would have coalesced⁶. 然而，要是弱了一点，什么东西也不会聚集在一起。

The universe would have remained forever a dull, scattered⁷ void. 宇宙会永远是单调、分散、虚空的。

This is one reason that some experts believe there may have been many other big bangs, perhaps trillions and trillions of them, 有的专家之所以认为也许有好多别的大爆炸，也许有几万亿次大爆炸，

spread through the mighty⁸ span of eternity⁹, and that the reason we exist in this particular one is that this is one we could exist in. 分布在无穷无尽的永恒里，这就是原因之一；我们之所以存在于这个特定的宇宙，是因为这个宇宙适合于我们的存在。

As Edward P. Tryon of Columbia University once put it: 正如哥伦比亚大学的爱德华·P.特赖恩所说：

"In answer to the question of why it happened, I offer the modest proposal that our Universe is simply one of those things which happen from time to time." "要回答它为什么产生了，我的敝见是，我们的宇宙只是那些不时产生的东西之一。"

To which adds Guth: "Although the creation of a universe might be very unlikely, 对此，古思补充说："虽然创建一个宇宙不大可能，

Tryon emphasized that no one had counted the failed attempts." 但特赖恩强调说，谁也没有统计过失败的次数。"
