| 9 | evolution of time itself is confusing. | 时间本身的演变令人困惑。 |
| 10 | It starts with Isaac Newton who said that time is like an | 从艾萨克·牛顿开始说 时间就像一个 |
| 11 | so one second on the earth is one second and Jupiter. | 所以地球上的一秒钟就是一秒钟和木星 |
| 12 | Einstein gives us a river of time that | 爱因斯坦给了我们一段时间 |
| 13 | speeds up and slows down and perhaps even has whirlpools which would correspond to perhaps | 加快速度,减速 甚至可能还有螺旋池,这也许与 |
| 14 | black holes. | 黑洞 黑洞 黑洞 黑洞 黑洞 |
| 15 | Comes the quantum theory and the quantum theory is that the river of time can fork | 量子理论和量子理论认为 时河可以叉 |
| 16 | fork into many smaller rivers and now we have something called string theory which is what I | 叉入许多较小的河流 现在,我们有 叫做弦理论,这就是我 |
| 17 | for a living and in string theory it explains not just time but all the subatomic particles. | 它不仅解释了时间,还解释了所有亚原子粒子 |
| 18 | There's nothing but musical notes on a tiny vibrating string and so time now we realize | 微小的震动弦上除了音乐音符什么也没有 所以时间到了 |

| 153 | long. | 长。 |
| 154 | You have a spacecraft 100 meters long and then the spacecraft moves close to the speed of | 你有一个飞船100米长 然后飞船移动接近速度 |
| 155 | it becomes contracted. | 它变成了合同。 |

| 162 | You know this paradox you | 你知道这个悖论你 |
| 163 | teach it at class and I explain why it's not a paradox. | 在课堂上教它,我解释为什么它不是一个悖论。 |
| 164 | Yeah and then here is your solution. | 是啊,然后这里是你的解决方案。 |
| 165 | There is no absolute simultaneity. | 没有绝对的兴奋。 |
| 166 | So one of them says I close the two doors at the same time and | 其中一个说我同时关了两扇门 |
| 167 | open them. | 打开 |
| 168 | The other said you lie to me you close this one and open and close this one and open. | 另一个说你骗我 你关上这个 打开这个 打开这个 |
| 169 | That means Tim that the two events coexist a long time. | 就是说 蒂姆说这两个事件并存了很长时间. |
| 170 | The whole Lorentz contraction oh yes | 整个洛伦茨的收缩 |
| 171 | the whole Lorentz contraction is just by Minkowski's genius idea treating time as | 整个洛伦茨的收缩 仅仅是因为明考斯基的天才想法 把时间当作 |
| 172 | a dimension. | 一个维度。 |
| 173 | You wouldn't get the Lorentz contraction. | 你不会得到洛伦茨的收缩。 |
| 174 | You wouldn't get time dilation | 你不会得到时间扩张 |

| 176 | Now to say that | 现在说 |
| 177 | time is moving let me be the devil's advocate because this is what they say. | 时间正在流逝 让我做魔鬼的倡导者 因为这就是他们说的话 |
| 178 | If you say that | 如果你这么说 |
| 179 | there is a now that moves moving means being in one place at one time at another place at another | 移动意味着在一个地方 在一个地方 在另一个地方 |
| 180 | time. | 时间。 |
| 181 | What is the velocity of the now moving? | 现在移动的速度是多少? |
| 182 | This is why people say don't say the time move. | 这就是为什么人们说不要说时间移动。 |
| 183 | You are mixing categories. | 你们是混合类别。 |
