Musings on Lorentz Violation Given the Recent Gravitational-Wave Observations of Coalescing Binary Black Holes
The recent observation of gravitational waves by the LIGO/Virgo collaboration
provides a unique opportunity to probe the extreme gravity of coalescing binary
black holes. In this regime, the gravitational interaction is not only strong,
but the spacetime curvature is large, characteristic velocities are a
non-negligible fraction of the speed of light, and the time scale on which the
curvature and gravity change is small. This contribution discusses some
consequences of these observations on modifications to General Relativity, with
a special emphasis on Lorentz-violating theories.Comment: Presented at the Seventh Meeting on CPT and Lorentz Symmetry,
