Query: Black holes and gravitational waves: simultaneous discovery by initial
  laser interferometers   Study of gravitational-radiation induced merging rates of relativistic binary
stars (double neutron stars; neutron star + black hole; double black holes)
shows that the first-generation gravitational wave interferometers with an
rms-sensitivity of $10^{-21}$ at frequency 100 Hz can detect 10-700 black hole
and only $\sim 1$ neutron star coalescences in a 1-year integration time in a
wide range of stellar evolution parameters. It is notable that modern concepts
of stellar evolution predict that the first detection of gravitational wave
will independently discover black holes.
