This weak lensing is not surprising, but it could test some aspects of gravitation . What would be curious is if there is a strong lensing. A gravitation wave front with some Weyl curvature has a part of it wind around the intervening mass. This would result in multiple signals and a further delayed signal. The Weyl curvature is conformal, which is really a form of the Huygens' principle. This splitting of light and now gravitational waves by intervening gravitating masses is a sort of beam splitter. In effect these detections are to gravitational waves what classical optics is to light. LC -- You received this message because you are subscribed to the Google Groups "Everything List" group.
