Seven thousand light years from home距离地球7000光年Its as though were in a forest thick with trees.似乎我们置身于树木浓密的森林中Each so beautiful, so fascinating, its impossible to look beyond每棵树都那么美丽、迷人,不可能遥望外面to see the bigger picture.去看到全局We have to find a way through我们必须找到出路to reach the clearing at the galaxys edge抵达星系边缘的开阔地带But faced with sights like this, its hard to leave但是面对这样的美景,让人流连忘返(天鹰星云)A colossal glowing cloud topped by these great towers of dust庞大的发光云团上面矗立着这些巨大的尘埃高塔the Pillars of Creation它们是创世之柱Like a gateway into the unknown.犹如进入未知世界的大门A star factory packed with embryonic star systems这是是一个布满胚胎期恒星系统的工厂each larger than our solar system.每一个恒星系都像我们太阳系那么大we have to resist its siren song, tear ourselves away我们必须赶紧离开,否则会无法自拔to carry on towards the edge of the galaxy以便能继续前进到星系的边缘Dazzled by the Milk Ways beauty, weve been blinded to its terrors炫于的美丽,我们无视它的危险and strayed into a cosmic minefield于是闯进了宇宙雷区Like an explosion in slow motion.好像是一场慢动作的爆炸场面A massive star, millions of times brighter than our sun.一颗巨大的恒星,亮度是我们太阳的数百万倍Its going into meltdown它正在崩解The fuel that sustains it is running out维持它的燃料即将耗尽the nuclear reactions that power it winding down给它提供能量的核反应正在逐渐减少Were watching its death throes我们看到是它的垂死挣扎An even bigger, dangerously unstable star一个更大的,险象环生的不稳定恒星But this ones about to explode但是这个会爆炸And when a star this big dies像这样一个巨大恒星死亡时its a hundred times more violent than a supernova.爆炸比超新星剧烈一百倍Weve stumbled into the most violent star death of all无意中我们撞见了最剧烈的恒星之死a hypernova.超超新星The cores collapsed, its becoming a black hole.它的核心坍塌了,正在变成一个黑洞201507/386657

I once said that I was unhappy with the explanation given in terms of negative energy particles being created.我曾经说过 对粒子负能量子的产生的解释 让我很不满意But I feel this is part of the controversy of science.不过 我觉得这是科学思辩的一部分You must have the give and take, and Im delighted to be a part of that.你必须有所取舍 我很开心自己参与了这场思辩Thats what makes it fun.If you all sat down and said, ;Oh, lovely;这是个很有趣的过程 当人们的脑子里萦绕着闹人的疑惑时when you do have niggling questions in your mind thats not doing a service to science.如果所有人都试图忽略他们 那么这实际上对科学毫无意义的But I was not antagonistic to it in any way except for that one time when I questioned.不过我对这并不抵触 除非脑子里不安生的人是我I finally convinced myself that black holes radiate最终我说自己 黑洞确实有辐射when I found a mechanism through which this could happen.我找到一种黑洞辐射的机制According to quantum mechanics space is filled with virtual particles and antiparticles根据量子力学 空间充满虚粒子和反粒子that are constantly materializing in pairs separating, coming together again and annihilating each other.它们成对地以实物形式存在 分离然后靠近 共同湮灭In the presence of a black hole one member of a pair of virtual particles在黑洞附近 上述一对虚粒子中的一个may fall into the hole leaving the other member without a partner with which to annihilate.可能落进黑洞 这样剩下在外面的一个就失去了伙伴 没法湮灭The forsaken particle appears to be radiation emitted by the black hole.And so black holes are not eternal.于是就成为辐射 被黑洞释放出来 所以黑洞并不能永远存在They evaporate away at an increasing rate until they vanish in a gigantic explosion.它们以一个不断增加的速率蒸发 直到在一次巨大的爆炸中灰飞烟灭Quantum mechanics has allowed particles and radiation to escape from the ultimate prison a black hole.量子力学允许粒子和辐射 从黑洞这种终极监狱中 逃逸出去201604/437582

  我们认为宇宙是寂静无声的。但物理学家詹纳·莱文告诉我们,宇宙有着自己的配乐 -- 一部声音的作品,它记录着那些外层空间中最为激动人心的事情。(比如,黑洞在撞击时空的过程中发出的“鼓声”。)一种能被人强烈感知到的声音正穿越宇宙,向我们走来。201503/362130。
