LIGO观测到光程差证明了推迟引力波是各向异性的

In 2015, LIGO detected the first gravitational waves, thought to be the result of two black holes mergingit is a major &nbsp;breakthrough in exploration for a century. The mainstream physical interpretation of the optical path difference recorded by the interferometer is that, due to the polarization characteristics of the quadrupole moment, the two optical arms of the Michelson interferometer are stretched and compressed respectively, resulting in different deformation, and then resulting in the optical path difference. This article proposes a different understanding. We have proved that the electromagnetic wave emitted by a moving source charge is anisotropic and travels at different speeds in different directions. Extending this idea to gravitational waves leads to a natural corollary: retarded gravitational waves from sources of moving mass are anisotropic, that travel at different speeds in different directions, resulting in a wave path difference. This physical picture is natural and clear, which seems more reasonable.<br />&nbsp;
