Abstract
The discovery of two neutron stars tightly orbiting each other suggests that the rate of neutron-star mergers in the Universe is higher than had been thought — which is good news for seekers of gravitational waves.
The emission of gravitational waves by accelerated masses — such as two compact stars orbiting each other — is predicted by Einstein's theory of general relativity. In 1993 Taylor and Hulse earned the Nobel prize for their precise measurement of the rate of orbital decay of the binary pulsar PSR B1913+16 by the emission of gravitational waves1.
