[Physics] Does gravity have 'elasticity'? If a solid sun-sized object zooms across space at the speed of light, then abruptly stops, does it take gravity some time to 'settle' around it?

Hah tell me about it. The 2017 neutron star merger happened while I was writing a proposal for an experiment where the physics was sort of related. So of course I completely reframed the proposal around that event, and it got funded! And that was just a few years ago, right?

Man I really need to publish the results of that project…
