用心制作的纪录片真是个好东西，在现世的浮躁里，低语着知识和智慧的无疆，教得人谦卑，更可贵的是它可以让一个当代成年人感到重生，是关于好奇心的重生，甚至在某些领域是初生。我理解为什么很多人想要永葆容颜青春，但他们中大多数人却无视内心的青春，而内心的青春，是靠好奇心和由好奇心驱使的像宇宙一样不断扩张的边界来保鲜的，那是个人宇宙边界的多次重生，当然了，不是所有人都想要体会生活在更大的宇宙里，这也没什么。最近有闲看了一部行星的纪录片，the planets，还有一部关于宇宙和地球史的纪录片cosmos，前面是BBC，后面是NG，让人在光年里神游不是梦，生活在这个时代，比前人看到更广阔又具体的宇宙亿年历，真的是太幸运了。太阳会在50亿年后燃烧殆尽，届时地球这个目前唯一生命可知存在的行星会再次沦为寂静的星尘、气体和云团，幸运的话人类的后代早已移居别处，不知道他们会不会记得，在太空服役20年的“旅行者”探测器在最后经过冥王星即将遁入无边暗界的时刻回望了一眼的地球，它是卡尔萨根口中的“the pale blue dot”，它那时有45亿岁那么大了，它曾是家。
“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.”
