宇宙时空之旅

“在那里，那是家园，那是我们。在那里，你爱的每个人，你认识的每个人，你听说过的每个人，在这世上存在过的每个人，度过了自己的一生。
聚集在这里的，是我们的欢乐和痛苦，是成千上万的宗教信仰、意识形态，和经济学说每个猎手与觅食者，每个英雄与懦夫，每个文明的创立者和毁灭者，每个国王与农夫，每对年轻的爱侣，每一个母亲与父亲、充满希望的孩子们，发明家与探险家，每一位高尚的教师、每一位贪腐的政客，每一位超级明星、每一位最高领袖，人类史上的每一位圣人和罪人，都生活在这里，
如一粒微尘，悬浮在一束阳光之中。地球是一个很小的舞台，在浩瀚的宇宙背景下，想想过去的血流成河，那为帝王将相而流的血，只为让他们在光荣和胜利中，成为瞬间的伟人，占有那一个小点中…那一小部分。想想那无尽的残酷，图像里那一个像素点的某个角落的民众，每天把这残酷施加到与他们没什么区别的另一个角落的民众身上。他们为何常常误解，他们为何渴望杀死对方，他们的憎恨为何如此狂热。
我们在装模做样，我们自以为很重要，妄想着我们人类地位特殊，在宇宙中与众不同，这一切，都因这泛着苍白蓝光的小点而动摇。我们的星球，不过是一粒孤独的微尘，笼罩在伟大的宇宙黑暗之中。
我们默默无闻，沉浸在无尽的浩瀚里，没有一丝线索显示，除了我们自己，
还有谁能拯救我们。地球是目前已知唯一有生命的世界，生命再无其他去处，至少在不久的将来，亦是如此。没有外星球，供人类迁移，只可参观，不能定居。不管你喜欢与否，现在，只有地球供我们立足。据说研习天文，可以让人谦卑，塑造人心，磨炼个性，也许再没有更好的方法能比这遥远的画面更好地显示出人类的自负与愚蠢。
对我而言，它强调了我们的责任，要对人更友善，懂得珍惜与爱护，这泛着苍白蓝光的小点是我们知道的唯一的家园。
“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.

(由旅行者1号于1990年2月14日在距离地球60亿英里处拍摄，拍摄完照片后，旅行者1号驶离太阳系，踏上寻找其它文明的漫漫征途。在照片中的地球，只有一个像素点大小。)

第13集临近结尾Neil deGrasse Tyson引用卡尔萨根关于地球——the “Pale Blue Dot”——解说词。

Carl Sagan titled his 1994 book Pale Blue Dot: A Vision of the Human Future in Space after the photograph. In it, he expresses his thoughts on a deeper meaning of the image:

From this distant vantage point, the Earth might not seem of any particular interest. But for us, it's different. Consider again that 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 of our tiny world. 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.

遵从5条简单规则who took five simple rules to heart.
1、质疑权威Question authority.
不轻信人言No idea is true just because someone says so,
包括自己在内including me.
2、独立思考Think for yourself.
3、自我质疑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.
相信不代表能成为现实Believing something doesn't make it so.
4、依靠观察与实验 Test ideas by the evidence gained
以实证检验想法from observation and experiment.
如果自己喜欢的想法没有通过全面的检验If a favorite idea fails a well-designed test,
它就是错的it's wrong!
乐观一点Get over it.
遵循证据 无论它指向哪里Follow the evidence, wherever it leads.
如果没有证据 不妄下定论If you have no evidence, reserve judgment.
5、也许最重要的规则就是 And perhaps the most important rule of all...
要记住 你也会犯错Remember, you could be wrong.
即使是最优秀的科学家Even the best scientists
也曾经在某些事情上犯错have been wrong about some things.
牛顿 爱因斯坦Newton, Einstein,
还有历史上每一位伟大的科学家and every other great scientist in history,
他们都犯过错they all made mistakes.
这很正常 是人都会犯错Of course they did-- they were human.


科学让我们不再欺骗自己Science is a way to keep from fooling ourselves...
欺骗别人and each other.
科学家们有罪吗Have scientists known sin?
有的Of course.
我们曾滥用科学We have misused science, just as we have
就像手边的工具一样随意使用every other tool at our disposal,
因此我们不能把科学and that's why we can't afford
放在少数的掌权者手中to leave it in the hands of a powerful few.
当科学更多的属于全人类时The more science belongs to all of us,
它就越不会被乱用the less likely it is to be misused.
科学的价值能阻止These values undermine the appeals
狂热与无知of fanaticism and ignorance

我们成功地（从外太空）拍到这张照片，细心再看，你会看见一个小点。就是这里，就是我们的家，就是我们。在这点上每个你爱的人、每个你认识的人、每个你曾经听过的人，以及每个曾经存在的人，都在那里过完一生。 这里集合了一切的欢喜与苦难，数千个自信的宗教、意识形态以及经济学说，每个猎人和搜寻者、每个英雄和懦夫、每个文明的创造者与毁灭者、每个国王与农夫、每对相恋中的年轻爱侣、每个充满希望的孩子、每对父母、发明家和探险家，每个教授道德的老师、每个贪污政客、每个超级巨星、每个至高无上的领袖、每个人类历史上的圣人与罪人，都住在这里，一粒悬浮在阳光下的微尘。 在浩瀚的宇宙中，地球不过是一个很小的舞台，想想过去的血流成河，那些芸芸众生为帝王将相而流的血，只为让他们在光荣和胜利中成为瞬间的伟人，去占有那一个小点中的一小部分。想想那无尽的残酷，图像里那一个小点的某个角落的民众，每天把残酷施加到与他们没有区别的另一个角落的同胞身上，他们之间的误解如此频繁，他们多么渴望杀死对方，他们之间的憎恨又如此狂热。 我们在装模做样，我们自以为很重要，妄想着我们人类地位特殊，在宇宙中与众不同，这一切，都因这泛着苍白蓝光的小点而动摇。我们的星球，不过是一粒孤独的微尘，笼罩在伟大的宇宙黑暗之中。我们默默无闻，沉浸在无尽的浩瀚里，没有一丝线索显示，除了我们自己，没人能拯救我们。 地球是目前唯一有生命的星球，再无其他去处，至少在不久的将来亦是如此，没有外星球，供人类迁移，只可参观，不能定居。不管你喜欢与否，现在，只有地球供我们立足。 一直有人说天文学是令人谦卑，同时也是一种塑造性格的学问。对我来说，希望没有比这张从远处拍摄我们微小世界的照片更好的示范，去展示人类自负和愚蠢。对我来说，这强调了我们应该更加亲切和富同情心地去对待身边的每一个人，同时更加保护和珍惜这暗淡蓝点，这个我们目前所知唯一的家。

——奈尔·德葛拉司·泰森

这部科普片做得十分精致，并且内容丰富，大到极超新星的爆炸，小到电子对光线的影响，而且画面十分美丽，并且很多生物都拍摄得很好。
记忆最深的还是第一集，第一次看，就感觉到了对宇宙历史的极强的概括，像那张宇宙的日历，让整个宇宙历史化为了一年，我们都是在这个日历的最后一秒诞生的。第一集讲述了宇宙的起源，并且在整个十二集中都有很多的历史故事，能够让我们更形象地知道当时的故事。像这一集，就有科学家为了证明日心说而被判决死刑，但后来有这更多的人支持日心说，体现了科学的力量。
还有让我记忆犹新的就是恒星的毁灭，太阳这颗小恒星，最终会不断膨胀，最终爆开，会伤害周围很多的行星，最终成为一颗白矮星，只能发出一丝丝微弱的光。而那时的人类必定有能力去别的地方，而他们还会记得这颗培育了幼儿时的他们的恒星吗，就算它已没有了原本的样子，但还是值得珍惜的。有一些大的恒星毁灭就像一场灾难，他们会一直缩小缩小，直到这么多原子之间几乎没有了距离，然后爆炸，这就是一场灾难，会发出强烈的光，而且超新星会有更强的光，是太阳的几千倍还是几万倍，而且不久就会有一个离地球较远的超新星毁灭，那时会照亮整个南半球的天空。
这一系列中还有一个重要的东西，就是光。世世代代的人们研究光，有一种三棱镜能够让光分成七种颜色，而有人就是在测量温度是发现在最热的温度红色外面的温度计显示的温度居然比红色还高，这就是红外线，是一种不可见的光，还有很多这样子的光，而且用不同的光来看世界会有不同的样子，像有一种光就可以看见远处的宇宙爆炸。
这个系列也让我更加了解很多著名的科学家，像牛顿，伽利略，法拉第，爱因斯坦什么的。而且里面的那艘想象之舟特别漂亮，能不受时间和空间的概念，挺厉害的，还有那个神秘的宫殿，里面记录了各种生命的诞生，消亡，还有这一条空空的走廊，等着别人来填写。
最后一集，呼吁我们一起探索这个大无边界的宇宙，同时也要珍惜这个地球，这个沧桑的小白点。

这部片子的视角更偏重文艺片——宇宙发现的历史，就是人的困惑和斗争的历史。不断地探索科学，摸索科学的精神，是我们人类不断迈向宇宙的动力。
此片制作精良，从自然科学角度也特别适合作为中小学生的启蒙之作。生物学、物理学、化学课的许多概念都可以完美呈现，而且极富趣味。
最后，以第13集收官之语来表达我滔滔不绝的敬意。花了接近半个小时才手打出这些字。字字精华。
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, live 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 father and mother, hopeful child, inventor and explorer, every teacher of moral, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, live there...on the mote of dust suspended...in a sunbeam.
The earth is a every 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 so 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 this 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 know 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 the distant image. To me, it underscores our responsibility to deal more kindly with one another and to preserve and cherish the pale dot, the only home we've ever know.
How did we, tiny creatures living on this 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 form the prion? It was the work of generates of searchers who took five simple rules to heart:
Question authority. No idea is true just because someone say so, including me. Think for yourself.
Question yourself. Don't believe in something 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, where ever it lead. If you have no evidence, reserve judgement.
And perhaps the most important rule of all...Remember you could be wrong. Even the best scientists have been wrong about somethings. Newton, Einstein, and every other great scientist in the history, they all made mistakes. Of course they did--they are human. Science is a way to keep from fooling ourselves...and each other. Have scientists know sin? Of cause. We have misuse science, just as we have misuse 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. These values undermine the appeals of fanaticism and ignorance and, after all, the universe is mostly dark, dotted by islands of light.

依个人喜好摘录，绝大部分采集自网上下载的本片英文字幕，经过排版格式编辑整理，仅粗略核对过，不保证完全正确。


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.
