You can google gravitational waves and get lots of other discussions.

What information and knowledge it already has discovered is of course even more solid evidence, not only for BH's, but BH mergers, and of course the size range from stellar to intermediate mass BH's. 

In the future  as precision, tolerances, and sensitivities are further enhanced, we will discover gravitational waves from further back in time, [perhaps from the BB itself] and of amplitudes and frequencies beyond that which aLIGO and its ground base cousins are able to decipher at this present time. Perhaps the LISA project may reveal more.

GW waves can be used to gather information in much the same manner as EM radiation. The advantage is every object or particle in spacetime is affected, unlike EM which some particles do not interact with. It provides another resource of measurable interactions on all objects in our universe.
