Main Question or Discussion Point
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?
Thanks for the answer.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.
This is a good question, but one I suspect noone is able to answer at the moment. Numerical simulations like the one listed above use a variety of techniques, but they all get rid of the singularities. One way to do this is to simply not simulate anything inside the event horizon, since the details are irrelevant to the goal of the simulation.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?
Whoever told you that misinformed you. That just how it looks to an outside observer, NOT to things falling in, which don't even know the EH is there.... Because time is frozen at the event horizons maybe the mater and antimatter will never come in contact in finite time
Basically it means that things that seem to be invariant in all frames when viewed in everyday life may not actually invariant in all frame.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.
