The several already existing gravitational wave detectors have already detected signals believed to come from black hole-black hole, black hole-neutron star and neutron star-neutron star mergers. Using the time delta between detecting the same events at different detectors around the globe, we have inferred the directions the signals are coming from. The intensity curves of the events tell us details about the masses and other characteristics of the colliding object. Also over time the distribution of their masses and other characteristics will give us information about the populations and distribution of these objects, which can help validate our theories of star, neutron star, black hole and galaxy formation.
