第2章 欢迎来到太阳系 Welcome to the Solar System · 第6讲

1. 讲稿里说从太阳系到比邻星只是“sissy skip”，这词儿啥意思啊？为啥用这个词来形容，是嫌它太短了吗？
2. 作者把‘nothingness’、‘emptiness’和‘vacuum’放在一起说它们很像，那这三个词在描述太空时到底有啥细微区别？
3. 文中提到太阳系是单星系统，而Alpha Centauri是三颗星组成的“cluster”，那“cluster”除了指星星，平时还能咋用？
4. 外星人为啥要跑到地球搞麦田圈或者吓唬人？讲稿里说他们“must have teenagers”，这到底是啥逻辑？
5. 既然去银河系中心要花的时间远超人类寿命，那我们现在探索宇宙到底有啥实际意义？

1. What does 'sissy skip' mean in the lecture? Why did the author use this specific term to describe the distance to Proxima Centauri?
2. The author groups 'nothingness', 'emptiness', and 'vacuum' together as similar words. What are the subtle differences between them when describing space?
3. The text mentions that Alpha Centauri is a 'cluster' of three stars. Besides stars, how else can we use the word 'cluster' in daily conversation?
4. Why would aliens travel billions of miles to create crop circles or scare people? What is the logic behind the statement 'they must have teenagers'?
5. Since it would take longer than a human lifespan to reach the center of the galaxy, what is the actual significance of our current space exploration?

1 00:00:11,820 --> 00:00:12,400 Hey guys, 2 00:00:12,660 --> 00:00:16,500 we're going to find out whether this UFO has visited the 3 00:00:16,500 --> 00:00:19,020 Earth and created the crop circles. 4 00:00:20,880 --> 00:00:22,740 In the previous five lessons, 5 00:00:22,900 --> 00:00:26,220 the author guided us through a tour in the solar system. 6 00:00:26,590 --> 00:00:29,770 He said,so,that's your solar system, 7 00:00:29,950 --> 00:00:33,470 and what else is out there beyond the solar system? 8 00:00:33,870 --> 00:00:36,310 Well,nothing and a great deal, 9 00:00:36,490 --> 00:00:41,210 depending on how you look at it.可以说太阳系之外什么 10 00:00:41,210 --> 00:00:46,850 也没有也可以说有很多东西就看你从哪一个角度来看 11 00:00:46,850 --> 00:00:52,200 了 In the short term,it's nothing In the short term, 12 00:00:53,000 --> 00:00:57,800 从短期来看可以说什么也没有 The most perfect vacuum 13 00:00:57,800 --> 00:01:02,340 ever created by humans is not as empty as the emptiness 14 00:01:02,340 --> 00:01:04,360 of interstellar space 15 00:01:06,290 --> 00:01:13,590 人类所创造出来的最完美的真空也不可能跟星际空间 16 00:01:13,590 --> 00:01:19,510 的那种真空一样空 emptiness 相当于就是 vacuum 17 00:01:19,790 --> 00:01:20,670 空 18 00:01:20,800 --> 00:01:22,320 旷这个是名词, 19 00:01:22,400 --> 00:01:28,200 empty 的名词 interstellar spacestellar means 20 00:01:28,200 --> 00:01:32,940 starsinter means betweeninterstellar means between 21 00:01:32,940 --> 00:01:36,220 stars 星际空间 and 22 00:01:36,340 --> 00:01:40,060 there is a great deal of this nothingnessuntil you get 23 00:01:40,060 --> 00:01:43,200 to the next bit of somethingnothingness, 24 00:01:43,220 --> 00:01:47,660 emptiness,vacuum these three words are very similar 25 00:01:48,640 --> 00:01:54,360 这样的真空又是非常浩瀚无边要过非常久, 26 00:01:54,460 --> 00:01:59,040 走很远你才能够 get to the next bit of something 你才能 27 00:01:59,040 --> 00:02:04,140 够遇到一点什么东西也许是另一个星球而这个星球在 28 00:02:04,140 --> 00:02:10,120 地球人看来也许那是非常庞大的但是相对于那浩瀚的 29 00:02:10,120 --> 00:02:15,000 emptiness 或者 nothingness or vacuum 它又是多么渺小 30 00:02:15,000 --> 00:02:20,840 所以作者才说它是 bit of somethingnext bit of 31 00:02:20,840 --> 00:02:26,040 something 要走很远很远才能够看到那么点东西 Our 32 00:02:26,360 --> 00:02:30,600 nearest neighbor in the cosmosproximal century 33 00:02:31,670 --> 00:02:38,040 就是前面一课说的比邻星半人马做的比林星, 34 00:02:38,160 --> 00:02:40,920 which is part of the three star cluster, 35 00:02:41,100 --> 00:02:43,440 known as Alpha Centauri. 36 00:02:43,480 --> 00:02:47,290 Cluster means a group of similar things, 37 00:02:47,630 --> 00:02:49,910 for example,a cluster of buildings, 38 00:02:50,230 --> 00:02:52,390 or a cluster of children. 39 00:02:53,230 --> 00:02:57,930 Three star cluster,we also call it three star system. 40 00:02:58,190 --> 00:03:00,750 It means a system,a solar system, 41 00:03:01,030 --> 00:03:05,150 with three stars.我们先说自己的太阳系。 42 00:03:05,150 --> 00:03:08,170 太阳系是只有一颗主星的, 43 00:03:08,210 --> 00:03:14,470 但是银河系里的其他的恒星系多数都是有两颗主星, 44 00:03:14,650 --> 00:03:16,470 有的有三颗主星。 45 00:03:16,630 --> 00:03:22,210 那现在我们说的这个三颗主星的恒星系就叫做 Three 46 00:03:22,210 --> 00:03:26,960 Star Cluster,known as Alpha Centauri。 47 00:03:26,960 --> 00:03:32,660 Alpha Centaur i Centaur i 上次说过了是半人马座半人 48 00:03:32,660 --> 00:03:39,890 马座就是一个有着三颗主星的星座 Cluster means a 49 00:03:39,890 --> 00:03:42,310 group of similar things For example, 50 00:03:42,410 --> 00:03:46,230 a cluster of children A cluster of buildings 51 00:03:46,810 --> 00:03:50,790 Three star cluster means a three star system A three 52 00:03:50,790 --> 00:03:56,070 star solar system 我们拿自己的太阳系做比较吧太阳 53 00:03:56,070 --> 00:04:03,590 系是只有一颗主星的但是在银河系的其他的恒星系里 54 00:04:03,590 --> 00:04:09,350 面多数是有两颗或者三颗主星的那我们现在说的就是 55 00:04:09,350 --> 00:04:14,430 有三颗主星的星系 Three Star Cluster 这个有三颗主星 56 00:04:14,430 --> 00:04:17,690 的星系就叫做 Alpha Centaur i 57 00:04:18,540 --> 00:04:23,740 那 Proxim a Centaur i 就是前面说的半人马座的比邻星 58 00:04:23,740 --> 00:04:27,430 它就是 Alpha Centaur i 59 00:04:27,890 --> 00:04:35,010 这个三星系统中的最亮的最大的这一颗 Alpha 是希腊 60 00:04:35,010 --> 00:04:39,690 字母的排第一个的那个字母就是希腊字母表里边第一 61 00:04:39,690 --> 00:04:44,430 个字母写出来是这样的因为它是排第一的所以它就是 62 00:04:44,430 --> 00:04:49,930 老大 Alpha Centaur i 自然指的就是最亮的那一颗在一 63 00:04:49,930 --> 00:04:54,420 个狼群里边 Alpha Wolf 就是头狼好了, 64 00:04:55,210 --> 00:05:01,630 这个比邻星是离我们 4.3 光年之远但是, 65 00:05:01,870 --> 00:05:04,110 in galactic terms, 66 00:05:04,490 --> 00:05:09,290 galactic 前面已经说过了是 galaxy 的形容词也就是拿 67 00:05:09,290 --> 00:05:15,250 星系空间这样一个广大的背景去看的话它只是很小的 68 00:05:15,250 --> 00:05:21,010 一步只是 a sissy skip Sissy is an insulting word for a 69 00:05:21,010 --> 00:05:25,270 boy or man who does things that girls or women usually do 70 00:05:25,270 --> 00:05:32,280 用汉语说就是很娘娘腔的 Skip 是跳跃所以这并不是就 71 00:05:32,280 --> 00:05:40,130 是从我们太阳系到他们这个 proximal century 离我们 72 00:05:40,130 --> 00:05:46,410 最近的比林星并不是豪迈的一跃只是走了一小步就像 73 00:05:46,410 --> 00:05:49,130 小姐的小碎步一样 But 74 00:05:49,510 --> 00:05:53,430 that is still a hundred million times farther than a 75 00:05:53,430 --> 00:05:58,530 trip to the moon 但是跟登月旅行相比那 76 00:05:58,560 --> 00:06:02,760 可就大得多了 A hundred million times farther 77 00:06:04,470 --> 00:06:09,770 我们中国古代有后一摄日的神话天空中原来有九个太 78 00:06:09,770 --> 00:06:16,270 阳其实这并非不可能在其他的星系里头其他的类似太 79 00:06:16,270 --> 00:06:19,150 阳系的星系里头也许他们真的有九个呢 80 00:06:19,930 --> 00:06:27,210 这个就是想象中的在一个三星系统的星系里边在某一 81 00:06:27,210 --> 00:06:30,250 颗行星上看天空的情形 82 00:06:31,010 --> 00:06:33,370 那就有三个太阳 to 83 00:06:34,810 --> 00:06:37,730 reach it by spaceship would take at least 25, 84 00:06:38,110 --> 00:06:41,470 000 years and even if you make the trip you still 85 00:06:41,470 --> 00:06:44,910 wouldn't be anywhereexcept at a lonely clutch of stars 86 00:06:44,910 --> 00:06:47,130 in the middle of a vast nowhere 87 00:06:47,830 --> 00:06:53,850 如果要乘坐太空船前往的话那也得花上两万五千年而 88 00:06:53,850 --> 00:06:58,850 且就算是你到了那 you make the trip 你成功了 you still 89 00:06:58,850 --> 00:07:02,130 wouldn't be anywhereexcept at a lonely clutch of 90 00:07:02,130 --> 00:07:07,440 starslonely clutch ……（后略，完整文稿见视频页字幕）
