TED 英语演讲：我们从何而来 演说题目：Questioning the universe 演说者：Stephen Hawking There is nothing bigger or older than the universe. The questions I would like to talk about are: one, where did we come from? How did the universe come into being? Are we alone in the universe? Is there alien life out there? What is the future of the human race? 没什么比宇宙更广阔更久远的了。你们的问题中我想聊一下的是：你我何从?宇宙何来?宇宙中就只有我们?有外星异生物么?人类的未来将会如何? Up until the 1920s, everyone thought the universe was essentially static and unchanging in time. Then it was discovered that the universe was expanding. Distant galaxies were moving away from us. This meant they must have been closer together in the past. If we extrapolate back, we find we must have all been on top of each other about 15 billion years ago. This was the Big Bang, the beginning of the universe. 上世纪 20xx 年代之前，所有人都以为宇宙基本上是处于稳态，流金岁月，持恒不变。之后我们发现原来宇宙正在膨胀中。辽远星系一直飞离我们，这意味着它们必定曾相靠近。我们若往后推算，就会发现我们必都曾於约 150 亿年前，互相堆叠在一起。正是这 霹雳大爆炸 宇宙之起始。 But was there anything before the Big Bang? If not, what created the universe? Why did the universe emerge from the Big Bang the way it did? We used to think that the theory of the universe could be divided into two parts. First, there were the laws like Maxwells equations and general relativity that determined the evolution of the universe, given its state over all of space at one time. And second, there was no question of the initial state of the universe. 然而大爆炸前可有什么吗?若是没有，又是什么制造宇宙呢?宇宙缘何要从大霹雳中冒出呢?过往我们都认为宇宙论可分成两部分，首先，是定律。像麦克斯韦方程组和 广义相对论以其于同...
