The two neutron stars most likely merged to form a black hole, though the tiny bit of neutron star that escaped — and formed new elements — could get recycled into planets like Earth where aliens may eventually dig up the metals as we have.
两个中子星最可能合并成一个黑洞,但合并中四散出的碎块会形成新的元素,循环进入类似地球的星体,也许外星人正像我们一样挖掘这些金属矿藏。
什么是“引力波”?
引力波是由黑洞、中子星等碰撞产生的一种时空涟漪,宛如石头丢进水里产生的波纹。百年前,爱因斯坦广义相对论预言了引力波的存在,但直到2017年人类才首次探测到引力波,3名美国科学家因此获得今年的诺贝尔物理学奖。
Gravitational waves were first directly detected two years ago, proving Albert Einstein's theory of general relativity, and recently, three scientists were awarded the Nobel Prize in Physics for their work on that first detection. Those gravitational waves were the result of two black holes colliding, and the signal lasted for only a fraction of a second. Because black holes don't emit light, these waves were invisible and only "heard" as thumps.
引力波于两年前首次被发现,证实了爱因斯坦的广义相对论。最近,三位科学家因首次探测到引力波被授予诺贝尔物理学奖。他们成功探测到来自于两个黑洞合并的引力波信号,信号仅持续几毫秒。因为黑洞并不发射出光,因此引力波不可见,只能以急速跳动的形式被“听到”。
