Forgive me for being so imprecise here. I'm not much into black holes
That's alright, Ann. None of us here are into black holes. If we were, there'd be no way to communicate with any of you outside the hole!
Touché.

By the way, this is just my thoughts that aren't based on any science article, but in the Unification theory there are 4 kinds of forces. Gravity which only pulls and 3 magnetic forces that can push and pull equally. A bar magnet is an example. One side pulls and the other side can equally push.
There is only one magnetic force, which is the electromagnetic force. The other two forces are the strong and weak nuclear forces. As far as I know, the strong force only pulls, and I don’t know what’s up with the weak force.
I think the real distinction between the four interactions (a better, more modern term than "force") is that the electromagnetic, weak, and strong are all quantum in nature, mediated by specific particles. Gravity appears otherwise, and is mediated by the curvature of space, not by any particles (according to our current understanding).
