      Yes, we’re not entirely sure what happens when this occurs though. There is a lot of discussion at the moment about black holes evaporating due to Hawking radiation. I don’t really understand but it could be that all the mass in a black hole could be turned into radiation before it reaches another one to collide with I also remember reading a article on how event horizons (the edge’s of black holes) would interact. It was very confusing.

      Yes – they can merge together. http://hubblesite.org/explore_astronomy/black_holes/encyc_mod3_q6.html
