In between two singularities, does a particle experience gravity?
If a particle is exactly at the midpoint between two singularities, will its net experience of the gravitational force (ignoring the rest of the universe, natch) be zero? I guess it ought to be assumed to be a point particle: I get the feeling that hadrons' internal structures aren't completely uniform and so their quarks would experience slightly different gravitational pulls as they are not quite at the exact same point. Or something like that, blah blah. Anyway, let's go with an electron for argument's sake.
Does the curvature of spacetime at the midpoint return to zero because their effects cancel? Does that mean that, in between two black holes, a region is formed within the event horizons for which the singularities are naked due to the opposing gravitational fields canceling out?
And similarly, with the "ringularity" of a Kerr black hole, is there a singularity that is naked to anything within that disc of spacetime? Though at least that region itself would be contained beyond and hidden by the event horizon, I suppose.
It sounds fun - to observe a naked singularity you just have to be bold enough to pass between two black holes that are sufficiently close.
