First, a video. Yes, it is a scrambled egg. But as you look at it, I hope you’ll begin to feel just slightly uneasy. 首先，来段录像。对，这是个被搅拌的鸡蛋。但是，当你看它的时候，我希望你能开始感受到有一点点的怪异。 Because you may notice that what’s actually happening is that the egg is unscrambling itself. 因为你可能注意到了正在发生的是这个鸡蛋搅拌的...
But of course, life is more than just exotic chemistry. 但是当然，生命不仅仅是奇异的化学物质。 How do you stabilize those huge molecules that seem to be viable? 那是怎么稳定那些大量的、似乎有存活的分子的呢？ Well, it’s here that life introduces an entirely new trick. 这就是生命呈现的一个全新的窍诀。 You don’t stabilize the individual; you stabi...
So — Here we are, back at the convention center. 那么，我们现在回到演讲厅。 We’ve been on a journey, a return journey, of 13.7 billion years. 我们已经在一个旅行、一个追溯137亿年的旅行中。 I hope you agree this is a powerful story. 我希望你认同这是一个震撼人心的故事。 And it’s a story in which humans play an astonishing and creative role. ...
For most of that time of life on Earth, living organisms have been relatively simple — single cells. 地球的大多数时间，生物体多是以简单的单细胞存在的。 But they had great diversity, and, inside, great complexity. 但是它们是十分多样的，而且，内部结构极其复杂。 Then from about 600 to 800 million years ago, multi-celled organisms appear. 然后6亿年到8亿年之...
Now, the going gets tougher. The next stage introduces entities that are significantly more fragile, significantly more vulnerable, 现在，（变化的条件）就更加苛刻了。下一个阶段是初次形成的个体，个体是明显更加弱小，更加脆弱的， but they’re also much more creative and much more capable of generating further complexity. 但是它们也更加有创造力，也更加有能力创造更...
Let’s begin by winding the timeline back 13.7 billion years, to the beginning of time. 让我们把时间往回拨到137亿年前，也就是时间的开始。 Around us, there’s nothing. There’s not even time or space. 四周是什么也没有，根本没有时间与空间。 Imagine the darkest, emptiest thing you can and cube it a gazillion times and that’s where we are. 尽...

And this is how it works. Gravity is more powerful where there’s more stuff. 这就是它怎么运作的。重力场的作用力更大，拥有比较多的物质。 So where you get slightly denser areas, gravity starts compacting clouds of hydrogen and helium atoms. 所以这里我们有个密度稍微大的区域，重力场开始凝结成氢氦原子的原子云。 So we can imagine the early universe breaking up i...
So here’s a great puzzle: in a universe ruled by the second law of thermodynamics, 所以，这就是个大谜团：在宇宙中，在被热力学第二定律规范下， how is it possible to generate the sort of complexity I’ve described, 怎么样才有可能产生这种我刚才论述的那种复杂性 the sort of complexity represented by you and me and the convention center? 那种你，我和这个...
