Astronomers confirmed a key part of Einstein’s general theory of relativity in 2016 when they announced that the LIGO array had detected gravitational waves released by the collision of two black holes. The researchers won a Nobel Prize for the discovery. But they’re not done: In October, scientists announced the finding of two dead stars colliding — not only hearing the ripples in space-time they made, but confirming the event visually with powerful telescopes. Collisions of neutron stars are believed to be the source of all heavy metals in the universe, including gold and silver, and the detection by LIGO helps verify accepted explanations of how the chemistry of the universe formed.
天文学家在2016年宣布,LIGO阵列检测到了两个黑洞碰撞所释放出来的引力波,证实了爱因斯坦广义相对论的关键部分。研究人员因这项发现而获得了诺贝尔物理学奖。但是研究人员的发现仍未结束:10月,科学家们监测到了两颗中子星的碰撞,不仅听到了碰撞造成的时空涟漪,而且还用性能强大的望远镜在光学上确认了这一事件。中子星的碰撞被认为是宇宙中所有重金属的来源,包括黄金和白银,LIGO的探测有助于验证有关宇宙化学形成的解释。
