What would happen if two black hole event horizons crossed? I would speculate that a "Big Bang" type event. All this would happen in a pretty short period of time once the two horizons meet. They would create an even greater force on the two central black hole masses than they independantly exert. The mass/energy of the two holes would get pulled into the void they created and everything pretty much collides with lots of other stuff and then these huge waves of enegy/matter go out from this event forming anew a universe? Whatcha think? By the way if you have any credentials I would appreciate being told of them.
