After 100 years of theory and decades of experiments, astronomers have detected gravitational waves directly for the first time. The announcement, made recently by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and accompanied by a paper in Physical Review Letters, describes a powerful signal that ultimately began with the merger of two black holes located 1.3 billion light-years away.
The finding not only confirms yet another aspect of Albert Einstein’s theory of gravity, known as general relativity, but it also opens another avenue for researchers to observe and study the universe.
