A discovery of gravitational waves from binary black hole coalescences, reported by the LIGO Scientific and Virgo Collaborations, raises a possibility that measurements of them can provide strict verification of the fundamental laws of physics. We perform such an observational verification of CPT invariance in gravitational waves in this study. When CPT violation exists, if any, gravitational waves with different circular polarizations could gain a slight difference in propagating speeds. Hence…

TLDR
Analysis of gravitational-wave data from the first LIGO detection of a binary black-hole merger finds evidence of the fundamental quasinormal mode and at least one overtone associated with the dominant angular mode, and supports the hypothesis that the GW150914 merger produced a Kerr black hole, as predicted by general relativity.
