...having read my above post, I guess a better question would be what would happen if two black holes fell together, one matter, the other anti-matter, but the difference between the two is still big enough to cause a black hole?

Say the minimum mass for a black hole is x. Say the matter black hole's mass is 4x, and the mass of the anti-matter black hole is x. Would the infalling anti-matter black hole cause any gamma radiation to escape? Keeping in mind that the anti-matter black hole will have to pass well beyond the matter black hole's event horizon before touching any matter, I don't think so... But the event horizon should suddenly and quite dramatically shrink upon annihilation?

Curious...

Very curious...
