« Testing Lorentz Invariance within binary black holes. »

The recent detection of gravitational waves has opened a new avenue
towards the highly-relativistic and
dynamical strong-field regime of the Einstein equations. It's therefore
possible to test GR in a new arena
characterized by velocities comparable to the speed of light and by large,
dynamical curvatures. After
describing how gravitational waves and binary black holes can be used to
test GR, we will focus upon one
particular alternative: Lorentz-violating gravity. Although
Lorentz-invariance is at the heart of theoretical
physics, it's violation in the gravitational sector may lead to a quantum
theory of gravitation, for instance.
Thus, we will show the first steps towards the ambitious project of using
GW signals to test Lorentz-
violating theories.
