Consider the consequences of adding a single electron at the edge of the observable universe. The gravitational pull of this electron is enough to disrupt the trajectories of all air molecules on Earth after only 50 collisions… a fraction of a microsecond.
The gravitational waves propagate at the speed of light, so if you add an electron at the edge of the observable universe, I think it will take much more time until any effect of doing so reaches Earth.
Ah yes, I think that’s correct (although I am also not a physicist). A more accurate description would be “In a matter of minutes after the time its gravitational waves reach earth, human events are unfolding in a measurably different fashion than they would have had that electron never existed.”
