  In the Randall-Sundrum scenario, our universe is a 4-dimensional `brane'
living in a 5-dimensional bulk spacetime. By studying the scattering of bulk
gravity waves, we show that this brane rings with a characteristic set of
complex quasinormal frequencies, much like a black hole. To a bulk observer
these modes are interpreted as metastable gravity wave bound states, while a
brane observer views them as a discrete spectrum of decaying massive gravitons.
Potential implications of these scattering resonances are discussed.
