第2章 欢迎来到太阳系 Welcome to the Solar System · 第6讲S1

1. 老师，讲稿里反复提到 emptiness, nothingness 和 vacuum 这三个词，它们到底有啥区别呀？是不是可以随便互换使用？
2. 文中说从太阳系到比邻星（Proxima Centauri）只是 'a sissy skip'，为什么用 'sissy' 这个词？它在这里具体指代什么样的动作或感觉？
3. 作者把太阳系称为 'one-star system'，而把 Alpha Centauri 称为 'three star cluster' 或 'system'。既然 cluster 和 system 意思相近，为什么这里要特意区分这两个词？
4. 为什么作者说到达银河系中心的时间 'far longer than we have existed as beings'？这里的 'beings' 除了指人，还有没有其他隐含的意思？
5. 如果星际空间真的像文中说的那么空旷，连 'next bit of something' 都要走很久才能碰到，那 UFO 真的可能藏在这些 'vast nowhere' 里而不被我们发现吗？

1. Teacher, the transcript keeps mentioning 'emptiness', 'nothingness', and 'vacuum'. What's the actual difference between them? Can I use them interchangeably?
2. The text says the trip to Proxima Centauri is just 'a sissy skip'. Why use the word 'sissy' here? What specific action or feeling does it refer to?
3. The author calls our solar system a 'one-star system' but refers to Alpha Centauri as a 'three star cluster' or 'system'. Since 'cluster' and 'system' seem similar, why is there a specific distinction made here?
4. Why does the author say it would take 'far longer than we have existed as beings' to reach the galactic center? Does 'beings' imply anything more than just humans?
5. If interstellar space is as empty as described, where you have to travel so long to find 'the next bit of something', could UFOs really hide in these 'vast nowheres' undetected?

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 --> 00:00:52,220 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 00:01:06,310 --> 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 --> 00:01:20,690 的那种真空一样空 emptiness 相当于就是 vacuum 空 17 00:01:20,820 --> 00:01:21,140 旷, 18 00:01:21,240 --> 00:01:22,320 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 --> 00:02:10,100 地球人看来也许那是非常庞大的但是相对于那浩瀚的 29 00:02:10,100 --> 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 --> 00:02:43,360 known as Alpha Centauri. 36 00:02:43,480 --> 00:02:47,330 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 --> 00:02:52,410 or a cluster of children. 39 00:02:53,210 --> 00:02:57,910 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 00:03:01,050 --> 00:03:06,730 with three stars.我们先说自己的太阳系太阳系是只 42 00:03:06,730 --> 00:03:13,090 有一颗主星的但是银河系里的其他的恒星系多数都是 43 00:03:13,090 --> 00:03:19,070 有两颗主星有的有三颗主星那现在我们说的这个三颗 44 00:03:19,070 --> 00:03:25,940 主星的恒星系就叫做 Three Star Clusterknown as Alpha 45 00:03:25,940 --> 00:03:31,260 Centaur i Alpha Centaur i Centaur i 上次说过了是半人 46 00:03:31,260 --> 00:03:36,680 马座半人马座就是一个有着三颗主星的星座。 47 00:03:36,840 --> 00:03:42,310 Cluster means a group of similar things.For example, 48 00:03:42,350 --> 00:03:46,230 a cluster of children,a cluster of buildings. 49 00:03:46,770 --> 00:03:49,990 Three star cluster means a three star system, 50 00:03:50,170 --> 00:03:52,030 a three star solar system. 51 00:03:52,290 --> 00:03:55,190 我们拿自己的太阳系做比较吧。 52 00:03:55,290 --> 00:03:58,070 太阳系是只有一颗主星的, 53 00:03:58,070 --> 00:04:03,770 但是在地,在银河系的其他的恒星系里面, 54 00:04:03,850 --> 00:04:07,210 多数是有两颗或者三颗主星的。 55 00:04:07,390 --> 00:04:11,430 那我们现在说的就是有三颗主星的星系, 56 00:04:11,530 --> 00:04:12,610 three star cluster。 57 00:04:13,010 --> 00:04:17,670 这个有三颗主星的星系就叫做 Alpha Centauri。 58 00:04:18,480 --> 00:04:23,720 那 Proxim a Centaur i 就是前面说的半人马座的比邻星。 59 00:04:23,720 --> 00:04:27,430 它就是 Alpha Centaur i 60 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 61 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 62 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 63 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 64 00:04:49,930 --> 00:04:54,420 个狼群里边 Alpha Wolf 就是头狼好了, 65 00:04:55,210 --> 00:05:01,650 这个比邻星是离我们 4.3 光年之远但是, 66 00:05:01,870 --> 00:05:04,110 in galactic terms, 67 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 68 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 69 00:05:15,250 --> 00:05:21,010 一步只是 a sissy skip Sissy is an insulting word for a 70 00:05:21,010 --> 00:05:25,270 boy or man who does things that girls or women usually do 71 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 72 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 73 00:05:40,130 --> 00:05:46,410 最近的比云星并不是豪迈的一跃只是走了一小步就像 74 00:05:46,410 --> 00:05:49,130 小姐的小碎步一样 But 75 00:05:49,510 --> 00:05:53,430 that is still a hundred million times farther than a 76 00:05:53,430 --> 00:05:58,530 trip to the moon 但是跟登月旅行相比那 77 00:05:58,560 --> 00:06:02,760 可就大得多了 A hundred million times farther 78 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 79 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 80 00:06:16,270 --> 00:06:19,150 阳系的星系里头也许它们真的有九个呢 81 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 82 00:06:27,210 --> 00:06:30,250 颗行星上看天空的情形 83 00:06:31,010 --> 00:06:33,370 那就有三个太阳 To 84 00:06:34,810 --> 00:06:37,710 reach it by spaceship would take at least 25, 85 00:06:38,110 --> 00:06:41,470 000 years and even if you make the trip you still 86 00:06:41,470 --> 00:06:44,910 wouldn't be anywhereexcept at a lonely clutch of stars 87 00:06:44,910 --> 00:06:47,130 in the middle of a vast nowhere 88 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 89 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 90 00:06:58,850 --> 00:07:02,130 wouldn't be anywhereexcept at a lonely clutch of 91 00:07 ……（后略，完整文稿见视频页字幕）
