The third detection LIGO shown as double black holes

Three is the magic number. LIGO collaboration has produced the third observation of gravitational waves emanating from a pair of merging black holes, and they provided us the most complete picture of how these pairs are formed and how to register them. “The first was a novelty. The second was a confirmation that the novelty of the first was not accidental. Third — it is astrophysics”, says a spokesperson for the LIGO David shoemaker from Massachusetts Institute of technology (MIT). “We are moving to a direct discussion of the populations of these objects.”
