``Gravitational waves propagate at the speed of thought.'' - Sir Arthur Eddington

Abstract: Gravitational waves have the potential to be a powerful tool for astrophysical and cosmological
science. We discuss the theory behind gravitational radiation (including the distance amplitude relation) , as well as
possible sources. We also study the LISA and LIGO detectors, and the cosmological significance of their observations. Finally,
we conclude with a brief discussion of why gravitational radiation is so intriguing to cosmologists.
