[04:13.490]One might hope that we could warp space time
[04:13.490]或许有人希望我们能够扭曲时空
[04:16.800]So that one could go off in a rocket and come back in the past
[04:16.800]这样我们可以乘坐火箭 回到过去
[04:20.800]But I have shown that this is not possible
[04:20.800]但我已经证明 如果能量密度不会达到负值
[04:23.000]If energy density is always non negative
[04:23.000]时间旅行无法实现的
[05:37.750]Are we alone in the universe？
[05:37.750]宇宙中就只有我们？
[05:40.750]Is there alien life out there？
[05:40.750]有外星异生物吗？
[05:43.750]What is the future of the human race？

[05:47.000]Up until the 1920s, everyone thought the universe was essentially static and unchanging in the time
[05:47.000]所有人都以为宇宙基本上处于稳态，流金岁月，持恒不变
[05:55.650]Then it was discovered that the universe was expanding
[05:55.650]之后我们发现原来宇宙正在膨胀中
[06:01.050]Distant galaxies were moving away from us
[06:01.050]辽远星系一直飞离我们
[06:05.000]This meant they must have been closer together in the past
[06:05.000]这意味着它们必定曾想靠近
[06:10.000]If we extrapolate back, we find we must have all been on top of each other about 15 billion years ago
[06:10.000]我们若往后推算,就会发现我们必都曾约150亿年前互相堆叠在一起
[06:19.650]This was the Big Bang,the beginning of the universe
[06:19.650]正是这大爆炸，宇宙之起始
[06:24.000]But was there anything before the Big Bang？
[06:24.000]然而大爆炸前可有什么吗？
[06:28.000]If not,what created the universe？
[06:28.000]若是没有,又是什么创造宇宙呢？
[06:32.000]Why did the universe emerge frome the Big Bang the way it did？
[06:32.000]宇宙为何要从大爆炸中冒出呢？
