What happens when a black hole devours another black hole? The bigger eats the smaller and increases in mass and size? What happens with the singularities?
The black holes undergo inspiral motion: their orbit decays through gravity wave emission, and then they are thought to merge. The merging phase is very brief (few miliseconds), produces another black hole, and understood primarily through numerical simulations.
But what happens to the topology of the ring singularities inside the common event horizon during the merger? Can a ring singularity be, for example, snapped into a singularity with loose ends? Or what happens, geometrically, on a triple junction of two loops of singularities after the two rings have touched?
... Because time is frozen at the event horizons maybe the mater and antimatter will never come in contact in finite time
Good evening Chill Factor. I must be missing something here. Are you saying that it is impossible in principle to station an observer at a position and in a manner such that he is at rest with respect to the black hole? Am I missing something when I read in the textbooks that to an observer not falling into the black hole and in a location well beyond the strongly curved spacetime near the hole that time will appear to slow in the close vicinity of the hole? Are you saying that if, someday, we discover a black hole within, say, a few hundred lightyears and its orientation is such that with the future's greatly improved space telescopes we can actually resolve the space occupied by the event horizon, that we will, in fact, be able to see infalling matter actually pass through the horizon? I think I understand the electromagnetics you mention, but I'm afraid I cannot see the analogy. But thanks.
