1、【#宇宙時(shí)空之旅# 第1集：立于銀河（宇宙起源）】尼爾沒(méi)有食言，在他乘座的那個(gè)酷炫的很有未來(lái)感的想象中的宇宙飛船帶領(lǐng)下，我果然見(jiàn)到了“比恒星大的原子”和“比原子小的恒星”。這正是莊子說(shuō)的“天下莫大于秋豪之末，而大山為小”，與片子中的布魯諾一樣，他憑想象便洞悉了宇宙的本質(zhì)。 http://url.cn/WLnf0T ——2015/4/20
2、【#宇宙時(shí)空之旅# 第2集：分子做的事（物種起源）】我們和一支蒼蠅或一棵樹(shù)的區(qū)別有多大？當(dāng)視角進(jìn)入到分子層面，我們發(fā)現(xiàn)我們有著同樣的雙螺旋結(jié)構(gòu)，無(wú)非是排列組合不同罷了。這樣，就會(huì)從科學(xué)層面理解宗教層面上佛教所說(shuō)的“眾生平等“”了。變異是進(jìn)化的前提，參差多態(tài)是世界的真相。 http://url.cn/dsT7gj ——2015/4/22

3、【#宇宙時(shí)空之旅# 第3集：知者無(wú)懼（萬(wàn)有引力）】千萬(wàn)年來(lái)來(lái)，在各大文明中，彗星一直是災(zāi)難的象征，直到1705年哈雷利用牛頓定律發(fā)現(xiàn)了它不過(guò)是一個(gè)每隔76年就會(huì)出現(xiàn)的星體。更令人震撼的是，人們根據(jù)牛頓定律預(yù)測(cè)了幾十億后銀河系將與仙女座星系合并，人們能夠看到維持十億年的星光秀！ http://url.cn/aBJ6lm ——2015/4/26

4、【#宇宙時(shí)空之旅# 第4集：相對(duì)論】“你如果去過(guò)黑洞還能活著回來(lái)，你可能會(huì)發(fā)現(xiàn)我們宇宙中的其他時(shí)間和空間。先不提相對(duì)論的第一條戒律：‘汝不可超越光速?！罩袥](méi)有什么速度可以比光速快，但太空并不空曠，空間可以延伸、收縮、被扭曲，那樣的話(huà)，時(shí)間也會(huì)被扭曲?！?a rel="nofollow" target="_blank">http://url.cn/UM8yx9 ——2015/4/25

5、【#宇宙時(shí)空之旅# 第5集：光的秘密（光的世界）】光是什么？墨子是發(fā)現(xiàn)光的第一人，卻把精力用在了政治上。海瑟姆發(fā)現(xiàn)光來(lái)自遠(yuǎn)方，而非眼鏡。牛頓用棱鏡發(fā)現(xiàn)了七彩成像，卻錯(cuò)過(guò)了更偉大的發(fā)現(xiàn)。赫歇爾發(fā)現(xiàn)了紅外線(xiàn)的溫度最高。約琴夫發(fā)現(xiàn)了光譜中的黑線(xiàn)……現(xiàn)在，我們的眼睛才剛剛睜開(kāi)。 http://open.163.com/movie/2014/3/R/P/MA069D2OR_MA06EUDRP.html ——2015/4/26
6、【#宇宙時(shí)空之旅# 第6集：微觀(guān)世界】人眼睛的原子數(shù)量比浩瀚的星空還要多，因此當(dāng)對(duì)事物的看法進(jìn)入到微觀(guān)層面，你便會(huì)理解佛家所說(shuō)的“一沙一世界”并非妄談了。而從本質(zhì)上講，人身上的原子與太陽(yáng)中的原子并無(wú)不同，從而，你也會(huì)體會(huì)到莊子所說(shuō)的“萬(wàn)物齊一”是怎么回事了。http://url.cn/YMnD2Q ——2015/5/22

7、游似:【#宇宙時(shí)空之旅# 第7集：地球年齡】彼得森本來(lái)一開(kāi)始只負(fù)責(zé)通過(guò)測(cè)量鉛的含量來(lái)測(cè)量地球的年齡，但無(wú)意中卻發(fā)現(xiàn)生活中充斥了大量的鉛，最終將矛頭指向了石化行業(yè)。所以這一集一開(kāi)始講得是一個(gè)科學(xué)問(wèn)題，后來(lái)成了一個(gè)環(huán)保問(wèn)題，這并不矛盾，因?yàn)榄h(huán)保需要科學(xué)的支持。 http://url.cn/RdK7vi ——2015/5/27
8、【#宇宙時(shí)空之旅# 第8集：宇宙星空】有三點(diǎn)感受。一，恒星主要有氫和氦組成。極簡(jiǎn)，然后極致，這是恒星的品質(zhì)。沒(méi)有生命，但可賦予其他星生命。二，恒星不恒。太陽(yáng)會(huì)膨脹，然后坍縮，成為白矮星，地球早晚會(huì)完蛋。三，有一種“日出”叫銀河系。換一個(gè)視角，世界可以如此美麗。http://url.cn/T9YyQv ——2015/6/12

9、【#宇宙時(shí)空之旅# 第9集：藍(lán)色星球】地球并不像我們想象的那么牢固，起初它只是渾然一體的大陸，后來(lái)才分開(kāi)，而且還將繼續(xù)變化。海底其實(shí)是一個(gè)更大的世界，那里有山脈，谷底，還有火山爆發(fā)。人類(lèi)并不比我們的祖先幸運(yùn)，我們?nèi)绻刂撇蛔∽约旱挠?，將?huì)死于自己之手。http://url.cn/a5RdCP ——2015/6/13
10、【#宇宙時(shí)空之旅# 第10集：電之驕子】在牛頓與愛(ài)因斯坦之間，有一個(gè)人叫法拉第。他發(fā)現(xiàn)了電與磁場(chǎng)的關(guān)系，改變了世界的速度，讓人們可以千里傳音傳圖。他的老師曾嫉妒他的成功讓他去研究鏡片，他一無(wú)所獲，拿了塊鏡片做紀(jì)念。多年之后這塊鏡片又讓他發(fā)現(xiàn)了電與磁與光的關(guān)系……http://url.cn/cz99nH ——2015/6/29

11、【#宇宙時(shí)空之旅# 第11集：科學(xué)探索】生命的起源有很多種，而外星說(shuō)始終顯得不可思議。但這一集卻充分論證了這一點(diǎn)。小行星撞擊地球，帶來(lái)石頭，也撞飛石頭，而石頭中卻可以隱藏生命，很有可能這些生命就是這樣進(jìn)行星際穿越的。于是便可想象，這個(gè)宇宙其實(shí)早已遍布了生命。http://url.cn/YrOvpH ——2015/7/11
12、【#宇宙時(shí)空之旅# 第12集：氣候變化】曾經(jīng)有一個(gè)星球像地球一樣適宜生命繁衍，但后來(lái)被溫室效應(yīng)給毀了，這就是金星。而現(xiàn)在地球面臨著同樣的危機(jī)，一百年來(lái)人類(lèi)向大地中排放了太多的二氧化碳，破壞了地球的呼吸，冰雪在融化，地球在變暖。而避免這一危機(jī)的最好方式是使用太陽(yáng)能。http://url.cn/fEpTez ——2015/7/14

13、【#宇宙時(shí)空之旅# 第13集：走向未來(lái)】我們對(duì)這個(gè)宇宙了解多少？什么叫暗物質(zhì)？就好比在黑夜中站在海邊的人，我們現(xiàn)在所看到的星系就像涌到暗邊的泡沫。當(dāng)旅行者一號(hào)飛越海王星向地球最后一次回眸時(shí)，地球不過(guò)是一束光線(xiàn)中泛著蒼白藍(lán)光的小點(diǎn)，那里有人類(lèi)所有的自負(fù)和愚蠢，當(dāng)然還有希望和榮光。http://t.qq.com/p/t/472451020506963?apiType=14 ——2015/7/21
14、【#宇宙時(shí)空之旅# 豆瓣總評(píng)】雖然只有13集，但斷斷續(xù)續(xù)竟然看了三個(gè)月。反過(guò)來(lái)說(shuō)，一個(gè)片子拉扯三個(gè)月還能讓人看完，足以證明它的魅力。我雖然搞的是文學(xué)，但卻也是個(gè)科學(xué)謎，對(duì)宇宙時(shí)空還保留著童年時(shí)的好奇心。但并沒(méi)有與之前的宗教觀(guān)念沖突，而是彼此印證。因?yàn)橛钪婕幢悴皇橇碛猩系郏仓辽俸芊?hào)“一沙一世界”的佛教宇宙觀(guān)。http://movie.douban.com/subject/24698699/ ——2015/7/22

非常精彩的科普片！了解宇宙，了解地球，更重要的是了解人類(lèi)，了解自己。
第一集：從宇宙起源說(shuō)到地球的起源，如果把地球的歷史在時(shí)間軸上濃縮到一年的12個(gè)月的話(huà)，那么人類(lèi)的歷史就是那最后幾秒鐘的時(shí)間。
在浩瀚的宇宙中，地球就像是大洋中的一滴小水滴。地球的產(chǎn)生是偶然的，人類(lèi)的產(chǎn)生也是偶然的。
第二集：物種的進(jìn)化。為什么北極熊是白色的，其實(shí)白色的熊是由于基因突變而造成的，大多數(shù)情況下，基因突變本身沒(méi)有優(yōu)劣，但環(huán)境選擇了基因，也就是說(shuō)環(huán)境的因素導(dǎo)致某些基因因素更加容易生存。白色的北極熊更加容易在冰雪覆蓋的環(huán)境中隱藏起來(lái)，這一基因元素改變了生活在北極的熊的繁衍。而狗的產(chǎn)生，不是由環(huán)境，而是人類(lèi)的馴化產(chǎn)生的。狗來(lái)自于狼，由于狼體內(nèi)的激素差別，某些狼可以親近人類(lèi)，并且能夠慢慢和人類(lèi)相處共同抗?fàn)帯Ｓ谑?，人?lèi)馴服了這些“狼”，并且把這些“狼”馴服成人類(lèi)需要的功能，比如長(zhǎng)的可愛(ài)的“狼”，成為了人類(lèi)的寵物，另一些“狼”，被馴服成了牧羊犬。物種的進(jìn)化，既有隨機(jī)性，又有人為性。隨著人類(lèi)在這個(gè)地球上的強(qiáng)大，人類(lèi)也越來(lái)越多地控制和改變著地球物種的進(jìn)化。
第三集：帶領(lǐng)人類(lèi)探索美麗宇宙的兩位偉大的科學(xué)家，牛頓和哈雷。哈雷彗星，每76年出現(xiàn)一次，這不是巧合。建立在牛頓的理論基礎(chǔ)上，哈雷發(fā)現(xiàn)了彗星的奧秘。彗星是離太陽(yáng)很遠(yuǎn)很遠(yuǎn)的冰石，受到萬(wàn)有引力和慣性的作用，它會(huì)以橢圓形的軌跡繞太陽(yáng)運(yùn)動(dòng)。而我們看到的長(zhǎng)長(zhǎng)的掃把，就是彗星遇熱而揮發(fā)的氣體。
第四集：當(dāng)我們仰望星空，感嘆繁星的時(shí)候，也許那個(gè)星星已經(jīng)不存在了。它們可能離我們幾萬(wàn)光年，以至于當(dāng)光傳到地球的時(shí)候，這顆恒星已經(jīng)毀滅。愛(ài)因斯坦告訴我們，光速是這個(gè)宇宙中的極限速度，當(dāng)另一個(gè)速度無(wú)限接近于光速的時(shí)候，時(shí)空就會(huì)發(fā)生扭曲。另一個(gè)我們并不熟悉的偉大科學(xué)家John Michell發(fā)現(xiàn)了暗星，也就是我們所說(shuō)的黑洞。黑洞，是質(zhì)量十分巨大的恒星萎縮而成的，所以它具有非常大的質(zhì)量，密度和引力，以至于光也難以逃脫它。那么既然黑洞我們無(wú)法看見(jiàn)，那么John Michell又是如何發(fā)現(xiàn)它的呢？John Michell發(fā)現(xiàn)有一些行星圍繞著某個(gè)軌跡在運(yùn)動(dòng)，而現(xiàn)代科學(xué)通過(guò)X光射線(xiàn)，再次證明了黑洞的存在。黑洞里面是什么？這個(gè)仍然是人類(lèi)需要探究的領(lǐng)域。黑洞的引力足夠大，以至于它可以將周?chē)男行嵌嘉M(jìn)去。它可能是電影中的時(shí)空隧道，帶領(lǐng)我們到達(dá)過(guò)去，或者到達(dá)另一個(gè)星系。黑洞里面也可能是另一個(gè)宇宙，而黑洞里面可能也存在黑洞，而地球可能也是存在于某個(gè)黑洞中。宇宙太神秘，神秘到即使人類(lèi)的腦洞打開(kāi)，還是無(wú)法知道它的秘密。
第五集：光的奧秘。從最早發(fā)現(xiàn)小孔成像的墨子，到1000年后偉大的阿拉伯文明，再到牛頓發(fā)現(xiàn)了光譜，William Herschel發(fā)現(xiàn)了光譜和溫度的關(guān)系，發(fā)現(xiàn)了不可見(jiàn)光-紅外線(xiàn)。夫瑯禾費(fèi)制造了分光儀，揭示了宇宙中不同物質(zhì)，光譜不同，通過(guò)對(duì)宇宙中物質(zhì)的光譜的分析進(jìn)一步探索宇宙的奧秘。人類(lèi)依靠這一個(gè)個(gè)天才，一步步登上科學(xué)探索的階梯。
第六集：微觀(guān)世界。人類(lèi)的歷史只有幾千年，而植物的歷史有幾億年。葉綠體從事太陽(yáng)能采集工作，是微觀(guān)世界的太陽(yáng)能電池。光合作用是終極能源，不會(huì)污染大氣。碳原子是世界上一切生物分子的支柱，碳基分子我們稱(chēng)為蛋白質(zhì)，組成生命的分子。氫原子的原子核中只有一個(gè)質(zhì)子，所以元素表中排第一位。兩個(gè)質(zhì)子的原子核，就需要有中子把它們聚集在一起。質(zhì)子越多，需要的中子就越多。
第七集：地球年齡。通過(guò)探測(cè)巖石來(lái)推算地球的年齡，最下面的一層是最古老的，通過(guò)把每一層的沉積時(shí)間加起來(lái)來(lái)推算地球的年齡，但是不同時(shí)期，每一層的沉積時(shí)間不同，所以科學(xué)家推算出的地球年齡差異很大。另一方面，最下面的一層巖石，也不能確定它是最古老的巖石。太陽(yáng)系形成時(shí)殘留的遺跡，它存在于木星和火星軌道間，這些是產(chǎn)生地球的原料。100萬(wàn)年左右之前，一個(gè)大的小行星恰巧撞擊了一顆較小的，這顆鐵質(zhì)小行星的碎片撞擊到地球上形成一個(gè)大坑，就在現(xiàn)在亞利桑那大峽谷所在的位置。如果我們知道這塊鐵的形成時(shí)間，那么就能知道地球的年齡。每種元素都有其固定的衰變時(shí)間，從鈾慢慢衰變成穩(wěn)定的鉛，所需的時(shí)間是恒定的。要了解地球真是的年齡，最好的辦法就是測(cè)量隕石的鉛。
測(cè)量鉛含量沒(méi)有那么簡(jiǎn)單，需要在一個(gè)高度潔凈的環(huán)境下，利用質(zhì)譜儀，測(cè)量樣本中鉛和鈾的含量。質(zhì)譜儀利用磁場(chǎng)將樣本中的元素分離，從而使各種元素可以被量化，最后通過(guò)測(cè)得的鉛和鈾的含量，知道地球的年齡是45億年。
羅馬人剛開(kāi)始大量使用鉛作為下水道，餐具。部分歷史學(xué)家認(rèn)為，羅馬的滅亡和鉛有關(guān)。那么為什么還要使用鉛呢，因?yàn)樗阋耍诱剐院?，制造?jiǎn)單。
為什么鉛對(duì)我們的危害那么大？因?yàn)楫?dāng)鉛進(jìn)入我們體內(nèi)時(shí)，它會(huì)假裝成鋅或者鐵這些細(xì)胞成長(zhǎng)的確需要的元素。細(xì)胞中的酶被鉛的偽裝迷惑，開(kāi)始結(jié)合，這個(gè)是致命的結(jié)合，因?yàn)殂U無(wú)法滿(mǎn)足對(duì)細(xì)胞至關(guān)重要的需要。鉛也會(huì)妨礙神經(jīng)系統(tǒng)，干擾對(duì)記憶能力至關(guān)重要的神經(jīng)末梢，對(duì)孩童更為有害。
直到克萊爾彼得森開(kāi)始研究地球的年齡，它發(fā)現(xiàn)在深海中鉛的含量很少，而淺海中鉛的含量要高出幾百倍，這是由于當(dāng)時(shí)美國(guó)含鉛汽油導(dǎo)致的。當(dāng)克萊爾彼得森在自然雜志上發(fā)表了關(guān)于鉛的研究后，觸動(dòng)了石油化工業(yè)的經(jīng)濟(jì)利益。堅(jiān)持20年之后，克萊爾彼得森獲得了最后的勝利。

依個(gè)人喜好摘錄，絕大部分采集自網(wǎng)上下載的本片英文字幕，經(jīng)過(guò)排版格式編輯整理，僅粗略核對(duì)過(guò)，不保證完全正確。


E2

Evolution really happened. Accepting our kinship with all life on Earth is not only solid science. In my view, it's also a soaring spiritual experience.

Science works on the frontier between knowledge and ignorance. We're not afraid to admit what we don't know. There's no shame in that. The only shame is to pretend that we have all the answers.


E3

The human talent for pattern recognition is a two-edged sword. We're especially good at finding patterns, even when they aren't really there -- something known as "false pattern recognition." We hunger for significance, for signs that our personal existence is of special meaning to the universe. To that end, we're all too eager to deceive ourselves and others, to discern a sacred image in a grilled cheese sandwich or find a divine warning in a comet.

……

It's called the Oort Cloud, after Jan Oort, the Dutch astronomer who foretold its existence back in 1950. ...... Oort was also the first to correctly estimate the distance between the Sun and the center of our galaxy. That's a big deal -- finding out where we are in the Milky Way. Our star is about 30,000 light-years from the center. Oort was also the first guy to use a radio telescope to map the galaxy's spiral structure. And he discovered that the center of our galaxy was a place of titanic explosions, the first indication that there might have been a supermassive black hole lurking there.
Does the fact that most of us know the names of mass murderers, but never heard of Jan Oort, say anything about us?

At the time, the World Society of London was the world's clearinghouse of scientific discovery. Its motto, "Nullius in verba," sums up the heart of the scientific method. It's Latin for "see for yourself." In other words, "question authority."


E6

Democritus of Abdera was a true scientist, a man with a passionate desire to know the cosmos and to have fun. This is the man who once said, "a life without parties would be like an endless road without an end."
- "You mean, that's it? That's all there is? Just a bunch of atoms in a void?"
- "Yep. Well, think about it. The world has to be made of countless indivisible particles in a void. Otherwise, nothing could move or grow, be divided or changed without atoms and empty space for them to move in. So don't be sad, my friends. Just think of the infinite possibilities that arise from different arrangements of those atoms. Hails to the atoms, in this cup and in this wine... And to the laughter they make possible."


E9

Each of us is a tiny being riding on the outermost skin of one of the smaller planets for a few dozen trips around the local star.


E11

Human intelligence is imperfect, surely, and newly arisen. The ease with which it can be sweet-talked, overwhelmed, or subverted by other hard-wired tendencies, sometimes themselves disguised as the light of reason, is worrisome. But if our intelligence is the only edge, we must learn to use it better. To sharpen it. To understand its limitations and deficiencies. To use it as cats use stealth before pouncing. As walking sticks use camouflage. To make it the tool of our survival.
If we do this, we can solve almost any problem we are likely to confront in the next 100,000 years.

Our remote descendants, safely arrayed on many worlds throughout the solar system and beyond, will be unified by their common heritage, by their regard for their home planet, and by their knowledge that, whatever other life may be, the only humans in all the universe came from Earth.
They will gaze up and strain to find the blue dot in their skies. They will marvel at how vulnerable the repository of all our potential once was, how perilous our infancy, how humble our beginnings, how many rivers we had to cross... before we found our way.


E13

We call it "dark energy," but that name, like "dark matter," is merely a code word for our ignorance. It's okay not to know all the answers. It's better to admit our ignorance than to believe answers that might be wrong. Pretending to know everything closes the door to finding out what's really there.

---------- (↓ Carl Sagan, "Pale Blue Dot") ----------

That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity – in all this vastness – there is no hint that help will come from elsewhere to save us from ourselves.

The Earth is the only world known, so far, to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment, the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image. To me, it underscores our responsibility to deal more kindly with one another and to preserve and cherish the pale blue dot, the only home we've ever known.

---------- (↑ Carl Sagan, "Pale Blue Dot") ----------

How did we, tiny creatures living on that speck of dust, ever manage to figure out how to send spacecraft out among the stars of the Milky Way?
Only a few centuries ago, a mere second of cosmic time, we knew nothing of where or when we were. Oblivious to the rest of the cosmos, we inhabited a kind of prison -- a tiny universe bounded by a nutshell. How did we escape from the prison? It was the work of generations of searchers who took five simple rules to heart:

Question authority - No idea is true just because someone says so, including me. Think for yourself.
Question yourself - Don't believe anything just because you want to. Believing something doesn't make it so.
Test ideas by the evidence gained from observation and experiment - If a favorite idea fails a well-designed test, it's wrong! Get over it.
Follow the evidence, wherever it leads - If you have no evidence, reserve judgment. And perhaps the most important rule of all...
Remember, you could be wrong - Even the best scientists have been wrong about some things. Newton, Einstein, and every other great scientist in history, they all made mistakes. Of course they did -- they were human. Science is a way to keep from fooling ourselves... and each other.

Have scientists known sin? Of course. We have misused science, just as we have every other tool at our disposal, and that's why we can't afford to leave it in the hands of a powerful few. The more science belongs to all of us, the less likely it is to be misused.


附：本片的一個(gè)英文的 Episode Guide 加各集內(nèi)容概要（概要其實(shí)相當(dāng)詳細(xì)，但并不是解說(shuō)詞的拷貝）：
http://evolution.about.com/od/Cosmos/

（一）
1995年秋，兩次颶風(fēng)之后，在安圭拉的加勒比島東海岸，成群的美洲綠鬣蜥正在登陸。它們緊緊抱住浮木和被颶風(fēng)連根拔起的樹(shù)木，很有可能是從260公里外的島嶼漂流而至的。它們?cè)谛率澜绶笔⒅两瘛?br>
我們可以虛構(gòu)，二三十億年前大質(zhì)量小行星群撞擊地球，在靠近地球時(shí)，它們被地球引力扯裂，同時(shí)地球表面也被強(qiáng)大的引力撕扯分崩，隨后的大撞擊將地表碎片高速拋濺出地球，速度最快的碎片擺脫地球引力，飛離地球軌道或漂浮在地月系附近的行星軌道上；速度其次的碎片環(huán)繞地球形成衛(wèi)星環(huán)；速度最差的碎片落回地面或彌漫在整個(gè)大氣層中。請(qǐng)注意，這些碎片或塵埃上帶有生命物質(zhì)，其中一些生命有可能在太空或高空環(huán)境中蟄伏數(shù)年數(shù)十年甚至更久遠(yuǎn)。

大撞擊有可能使得地表生命大面積滅絕，地球環(huán)境數(shù)年數(shù)十年不適合生命生存繁衍。當(dāng)環(huán)境開(kāi)始好轉(zhuǎn)，地表生命不完全是由零開(kāi)始。當(dāng)初彌漫在大氣中的生命有可能開(kāi)始落會(huì)地表，環(huán)地球繞飛的碎片化作流星雨重返地表，行星軌道上的地球碎片化作流星雨重返地表，蟄伏其中的生命得以復(fù)蘇。這些生命也有可能在太空環(huán)境中獲得變異，以新的生命形式重返地球。

再往遠(yuǎn)處說(shuō)，火星隕石或許帶來(lái)另一顆類(lèi)地行星的生命，彗星帶來(lái)更遙遠(yuǎn)的太陽(yáng)系外圍的生命。

（二）
生命的故事是一個(gè)島的故事、一個(gè)方舟的故事，這個(gè)島是指宜居的時(shí)空，島與島之間是難以逾越的屏障。一個(gè)宜居時(shí)空經(jīng)由非宜居時(shí)空與另一個(gè)宜居時(shí)空之間的過(guò)渡就是方舟。

一個(gè)人的精神有愜意的時(shí)候、有困頓的時(shí)候。無(wú)望中的自己，好比生命大滅絕時(shí)代的地球，當(dāng)事竟時(shí)移，自己仿佛被掏空，沒(méi)有復(fù)蘇的絲毫希望。

它們來(lái)了！

【所有你曾經(jīng)留意過(guò)、觸摸過(guò)、想過(guò)的，定不負(fù)你。終有一天，它們會(huì)變成你困頓時(shí)的領(lǐng)悟，詞窮之際的靈感。它們千里迢迢的來(lái)，只為了不辜負(fù)你對(duì)生命曾有過(guò)的那份天真與好奇，那種認(rèn)真與善意?！?br>

最末一段話(huà)來(lái)自懌婷。流星雨的故事來(lái)自紀(jì)錄片《宇宙時(shí)空之旅》。綠鬣蜥的故事來(lái)自道金斯《地球上最偉大的表演：進(jìn)化的證據(jù)》。

借此文紀(jì)念剛離開(kāi)我們的羅賓?威廉姆斯，同時(shí)獻(xiàn)給困頓中的我、困頓中的朋友們。

遵從5條簡(jiǎn)單規(guī)則who took five simple rules to heart.
1、質(zhì)疑權(quán)威Question authority.
不輕信人言No idea is true just because someone says so,
包括自己在內(nèi)including me.
2、獨(dú)立思考Think for yourself.
3、自我質(zhì)疑Question yourself.
不因自己想要相信 而相信任何事情Don't believe anything just because you want to.
相信不代表能成為現(xiàn)實(shí)Believing something doesn't make it so.
4、依靠觀(guān)察與實(shí)驗(yàn) Test ideas by the evidence gained
以實(shí)證檢驗(yàn)想法from observation and experiment.
如果自己喜歡的想法沒(méi)有通過(guò)全面的檢驗(yàn)If a favorite idea fails a well-designed test,
它就是錯(cuò)的it's wrong!
樂(lè)觀(guān)一點(diǎn)Get over it.
遵循證據(jù) 無(wú)論它指向哪里Follow the evidence, wherever it leads.
如果沒(méi)有證據(jù) 不妄下定論If you have no evidence, reserve judgment.
5、也許最重要的規(guī)則就是 And perhaps the most important rule of all...
要記住 你也會(huì)犯錯(cuò)Remember, you could be wrong.
即使是最優(yōu)秀的科學(xué)家Even the best scientists
也曾經(jīng)在某些事情上犯錯(cuò)have been wrong about some things.
牛頓 愛(ài)因斯坦Newton, Einstein,
還有歷史上每一位偉大的科學(xué)家and every other great scientist in history,
他們都犯過(guò)錯(cuò)they all made mistakes.
這很正常 是人都會(huì)犯錯(cuò)Of course they did-- they were human.


科學(xué)讓我們不再欺騙自己Science is a way to keep from fooling ourselves...
欺騙別人and each other.
科學(xué)家們有罪嗎Have scientists known sin?
有的Of course.
我們?cè)鵀E用科學(xué)We have misused science, just as we have
就像手邊的工具一樣隨意使用every other tool at our disposal,
因此我們不能把科學(xué)and that's why we can't afford
放在少數(shù)的掌權(quán)者手中to leave it in the hands of a powerful few.
當(dāng)科學(xué)更多的屬于全人類(lèi)時(shí)The more science belongs to all of us,
它就越不會(huì)被亂用the less likely it is to be misused.
科學(xué)的價(jià)值能阻止These values undermine the appeals
狂熱與無(wú)知of fanaticism and ignorance
