Black Hole Anti-Particle Speculation

[wmikewells]

Electrons and protons have anti-particles. Has there ever been any speculation or work done on whether a black hole has an anti-particle such that if the two were to collide, they would annihilate each other? Probably not, but I was just curious.

Black holes are the same whether they are made of particles or antiparticles, and if two of them collide you just get a bigger black hole.

black holes are not particles so it is nonsensical to talk about their being an antiparticle

Thanks for the clarification. That is interesting.

So, it is only particles that have anti-matter properties. That makes sense.
