Can LIGO test quantum gravity?
“The dynamics of a black hole merger and the way gravitational waves travel is sensitive to even smallest deviations from general relativity, like for example violations of the equivalence principle or the possibility that the graviton is not exactly massless. Bimetric gravity, higher-order modifications of general relativity, additional long-range interactions, or the gravitational aether – all these models will have to pass additional tests now.
