Abstract

We show that alongside the already observed gravitational waves, quantum gravity predicts the existence of two additional massive classical fields and thus two new massive waves. We set a limit on their masses using data from Eöt-Wash-like experiments. We point out that the existence of these new states is a model independent prediction of quantum gravity. We explain how these new classical fields could impact astrophysical processes and in particular the binary inspirals of black holes. We calculate the emission rate of these new states in binary inspirals astrophysical processes.

Highlights

Much progress has been made in recent years in quantum gravity with the use if effective field theory methods
We set limits on these masses using data from the Eöt-Wash pendulum experiment [15] and we turn our attention to astrophysical and cosmological probes of quantum gravity studying quantum gravitational contributions to the inspirals of neutron stars or black holes. We demonstrate that these new massive states predicted in a model independent way by quantum gravity can modify the potential between the two astrophysical
Astrophysical or cosmological events we are aware of involve energies below the Planck mass, an effective theory of quantum gravity valid up to MP may be all that we ever need

Summary

Introduction

Much progress has been made in recent years in quantum gravity with the use if effective field theory methods. In this paper we point out that the low energy particle spectrum of quantum gravity must contain two new classical fields together with the massless classical graviton whose existence was recently confirmed by the gravitational waves observations [11,12,13].
