I think 0.1G of acceleration difference would be felt as center of inertia shifts from center of mass. Presumably while you're moving. Even more so if weightles

I think 0.1G of acceleration difference would be felt as center of inertia shifts from center of mass. Presumably while you're moving. Even more so if weightless. If the wave is long enough or small amplitude enough you wouldn't feel it. For something like the neutron star collision, it would be relatively far but not far enough to not get fried by EM radiation.
