As gravitational waves are now being nearly routinely measured with interferometers, the question of using them to probe new physics becomes increasingly legitimate. WebJun 7, 2013 · Abstract. Finding solutions of the Regge-Wheeler equation is in many cases the first step in the study of Schwarzschild black holes and modern perturbation theory as well as many other fields.
