If, for instance, a black hole was losing matter to one or more other black holes, could there be a point where after enough matter was siphoned off, all the materials inside the black hole could extra spontaneously de-compress/expand or explode with heat/energy?
Or would the black hole just be sucked into the other black hole as a singularity? (how much of the mass is orbiting the black hole inside the event horizon and how much is actually inside the singularity or close enough?)
