FIRST SPACE-TIME RIPPLES DETECTED 发现第一个时空波 A hundred years after Einstein predicted their existence, faint ripples in the fabric of the cosmos finally made their debut. Called gravitational waves, these ripples are created by some of the most violent events in the universe. Despite their extreme origins, gravitational waves remained elusive for so long because their effects on the observable universe are very small. 100年前爱因斯坦就预言了时空波的存在，宇宙结构中的虚弱波动终于登场了。这些波被称为引力波，是由宇宙中一些威力最大的碰撞造成的。尽管引力波的来源巨大，但它却沉寂如此之久，因为它对我们察觉到的宇宙的影响微乎其微。 |
