Will a black hole cause scattering of a gravitational wave?
Answers
Explanation:
Scalar fields, vector fields, and tensor fields can all scatter off of black holes. C.f. Teukolsky equation for scattering of gravitational waves off of Kerr. More generally, look up perturbations of fields on black hole backgrounds. You can also find exercises in many GR books on scattering of scalar fields on Schwarzschild black holes which amounts to solving a separable wave equation using a curved space-time wave operator; for example see project 8.2 in Padmanabhan "Gravitation: Foundations and Frontiers". See also superradiance in Kerr. –
Explanation:
✔️ Gravitational waves will provide a test of Einstein's theory of general relativity under extreme conditions of gravity where it has never before been tested. ... Gravitational waves will also tell us about how many objects like black holes and neutron stars exist in the Universe.
