Split second?
Do rocks etc not presently on earth run that much faster tnan geolocated ones? Perhaps we should be equiping our future, astro, taiko, cosmo, naughts with shotguns and external speakers pre-programmed to shout (in whatever passes for the luminiferous ether) "PULL!", as well. No icon as neither Einstein nor Michaelson Morley.
Mind you, in very high G wells one could well imagine a scenario where locally they moved like fuck whilst still dawdling to the long way away located external observer.
