With Gravitational Waves(GW) one can "know" that the Objects is there - detect it without "seeing"-visually, it just because the object has a mass.

Anything moving and having a mass is emitting GW - current detectors are sensitive only for objects with masses equal to mass of many Suns 2x10^30 kg$2\times 10^{30} ~\rm{kg}$ (2 with 30 zeros).

Imagine one day may we have sensors-detectors able to detect movement of any objects with mass without seeing it ....
