When black holes meet there are two things to consider when contemplating the merger.

  1. Adding mass to give just the required angular momentum
  2. The fact that a black hole cannot deform prior to colliding because of there inherent rigidity

The first item would be required for both black holes simultaneously. With other mass falling towards a black hole there is the possibility of radiation carrying off any excess mass, but this is not allowed with black holes as the surface area can only increase. The second is required and makes it difficult to understand how the merging could physically occur.

More work needed, but see blog on 9 February 2016

Next, we suggest an answer to the question: where do supermassive black holes come from?
