Gravitational waves emitted by inspiralling and coalescing compact binaries consisting of neutron stars and/or black holes can be used to test fundamental predictions of general relativity and to explore the rich non-linear structure of gravitation. These systems are so clean that they also enable us to measure the masses, spins and orientation of the binary quite accurately. Catalogs of binary inspirals and coalescences can help us to accurately measure cosmological parameters, such as the Hubble parameter and the density parameter. The formation of a black hole, in some cases, after coalescence and the emission of quasi-normal modes of gravitational radiation will help us to directly see this unique event and to understand the structure of spacetime. Events such as the coalescence of supermassive black holes and capture of stellar mass compact objects by massive black holes at the centre of a galaxy will enable us to map the Universe out to cosmological distances, z >> 1. The detection of inspiral and coalescence wave forms and quasi-normal modes, by the first and future generations of interferometric gravitational wave detectors is, therefore, a highly rewarding exercise.
