Scientists make waves with their publicity efforts

ON MONDAY EVENING, scientists hailed the detection of gravitational waves from the merging of two neutron stars. Chinese observational technology played key roles in this. An article published by Beijing News comments:

Albert Einstein first forecast the existence of gravitational waves, or the ripples in space and time, in 1916. Now they have been detected five times.

Unlike the past four times when the gravitational waves came from the merging of two black holes, this is the first time that the waves have been produced by the merging of two neutron stars.
