  Using effective field theoretical methods, we show that besides the already
observed gravitational waves, quantum gravity predicts two further massive
classical fields leading to two new massive waves. We set a limit on the masses
of these new modes using data from the E\"ot-Wash experiment. We point out that
the existence of these new states is a model independent prediction of quantum
gravity. We then explain how these new classical fields could impact
astrophysical processes and in particular the binary inspirals of neutron stars
or black holes. We calculate the emission rate of these new states in binary
inspirals astrophysical processes.
