Black holes have almost no properties which allow us to tell anything
about them, except that they have spin, charge, and the apparent diameter
provided by the event horizon, which is apparently a function of mass.

I wonder what would happen if two holes with opposite spin, identical mass
and neutral charge collided.  Especially if the event horizon were small
enough...
