引力波与黑洞

Gravitational wave and black holes

2015年9月14日,LOGO探测到来自两个质量分别为29个太阳质量和36个太阳质量的黑洞并合产生的引力波。这是人类第一次探测到黑洞并合事件,也是第一次探测到来自宇宙的引力波信号。那么,什么是引力波?什么是黑洞?它们是怎么发生碰撞的?碰撞后又发生了什么?本文将做出解释。

On September 14, 2015, LIGO detected gravitational waves from the merger of two black holes 29 and 36 times the mass of the Sun. This is the first time for human beings to directly detect such waves and the first observation of a binary black hole merger. What are gravitational waves＇？ What are black holes？ How do they connect each other？ What happens when black holes collide？ Author will explain these for you.
