  The Multimessenger discovery of the merger of two neutron stars on August 17,
2017, GW170817 / GRB170817A, accompanied by a gamma-ray burst and an optical
kilonova, is a triumph of the ideas about the evolution of the baryon component
in the Universe. Despite the current uniqueness of this observation, the
obtained variety of experimental data makes it possible right now to draw
important theoretical conclusions about the origin of the double neutron star,
their merger, and the subsequent flare-up of the electromagnetic radiation. We
present that the discovery of the merger at a distance of 40 Mpc is in full
agreement with the very first calculations of the Scenario Machine (Lipunov et
al. 1987). In modern terms, the predicted rate is ~ 10 000 Gpc-3.
