i am thinking what if gravity is itself a negative mass particle? like, if you have something in front of a black hole right? how would it gain gravitational potential energy? if anything with positive mass can't cant out of a black hole?

if there is an object with zero inertia, and there are very strong forces pulling at the thing all around, but the forces all cancel each other out (so the object stays staionary) will it take any effort to start it moving? i find myself being able to argue both ways.. help
