天文学家的浪漫

当我们仰望星空，望向遥远的恒星和星系时，我们其实在仰望过去，因为那些光从遥远的天体到达地球需要时间。光从那个红点传播到我们这，差不多经历了整个宇宙史，我们看到的是一百三十亿年前，发生的事件，我们看到的是宇宙最初的一颗恒星爆炸灭亡的景象。

when we look up into the sky,at distant stars and galaxies,then we’re looking back in time,because the light from the red dot has been travelling to us for almost the entire history of the universe.you see, what we’re looking at here is an event that happened 13 billion years ago.what we’re looking at here is the explosive death of one of the first star in the universe.

从宇宙起源到最后一个黑洞消失的这个过程中，生命，正如我们所知，只有百分之千亿分之一的可能性，所以对我们来说，宇宙最惊人的奇迹不是恒星，不是行星，也不是星系，甚至根本就不是一个物质，而是时间里的一瞬间，那个瞬间就是现在。

as measured from its beginning to the evaporation of the last black hole.life,as we know it ,is only possible for one thousandth of a billion billion billion billionth of a percent. and that’s why for me the most astonishing wonder of the universe isn’t a star or a planet or a galaxy,it isn’t a thing at all,it’s a instant in time, and that time is now.

每个人，你所热爱的一切，你所憎恶的一切你所拥有的最宝贵的东西，在宇宙生命最为伊始的几分钟内，由自然力量合成，在恒星内部转化，或者在他们燃烧的消亡中诞生，当你去世的时候，这些碎片会将你送到宇宙中，进入无限的死亡又重生的轮回之中。

and every piece of everything ,of everything you love, of everything you hate ,of everything you hold most precious, was assembled by the forces of nature is the first few minutes of the life of the universe, transformed in the heart of the stars or created in their fiery deaths.and when you die, those pieces will be returned to the universe in the endless cycle of death and rebirth.

当我们注视太空的时候，我们也是在寻找自己的起源，我们的故事就是宇宙的故事，因为我们是恒星真正的孩子，注入我们身体的每一个原子和分子，都是从宇宙大爆发到现在的全部历史。

when we look out into space,we are looking into our origins .our story is the story of the stars, and
written into every atom ,and every molecule of our bodies ,is the entire history of the universe from the Big Bang to the present day.

我刚用相机捕捉到的，这个光点二八五十万年前就踏上了旅途，那时地球上还没有人类，远古的祖先能人，正在非洲广袤的平原上漫步，就是这些光线穿行于无垠宇宙的同时，人类不断进化，一代又一代的生老病死，周而复始。

The light that I’ve just captured in my camera began its journey 2.5 million years ago .At that time .on earth ,there were no humans .homo habilis ,our distant ancestors ,were roaming the plains of Africa, and as those light rays travelled through the vastness of space ,our species evolved, and thousands and
thousands and thousands of generations of humans lived and died.

太阳的命运也是所有恒星的命运，终有一天他都会消亡，宇宙终会陷入永无止境的黑暗之中，这便是时间箭头最深远的影响。

The fate of the sun is the same as for all stars ,one day, they must all eventually die and the cosmos will be plunged into eternal night and this is the most profound consequence of the arrow of time.
