Scientists “heard” the wave with the help of laser beams (激光束) sent through two pipes which form an angle of 90 between each other and are nearly 2,000 miles apart in the US. That equipment let them glimpse the nature of black holes. Together they made up the Laser Interferometer GravitationalWave Observatory (LICO)Gravitational waves were first observed in September 2015 and the second detection occurred three months later. The third detection, which the astronomers called GW170104, was made on January 4,2017. The astronomers believed their latest finding “provides clues about the directions in which the black holes are spinning”. “Black holes are beautifully simple. You just need two numbers to describe them completely: mass, how much they bend spacetime, and a spin, how much spacetime moves about them，” said Dr Christopher Berry of the University of Birmingham, one of the researchers in the project. “But it takes lots of hard work to measure these from our data. We now have wonderful mass measurements,
