The importance of stability in the three-body problem will be discussed in the context of three physical applications. Specifically the destruction of globular clusters as the orbit the galaxy; the disruption of stellar binaries by the massive black hole in the centre of the Milky Way; and a new method for discovering low mass extrasolar planets which are not detectable using available methods. This work was carried out during my PhD candidature at Monash University (Melbourne, Australia) based on a new formulism developed by Rosemary A. Mardling that predicts the long-term stability of three-body problem systems. This formulism predicts systems that are unstable to the eventual escape of one of the masses in a random walk process and can be applied to the general three-body problem.
