What would happen if a black hole swallowed an anti-matter black hole?

I see now thank you for answering my question beyond just "no"

What would happen if two black holes collided and one of them was anti-matter?

 

Like others stated previously, I believe the two black holes would merge and whatever energetic reaction, the matter-antimatter explosion, would be contained by the new black hole which will then have the mass of both. None of the energy could escape.

 

The question is how can these ever encounter each other? Maybe if there was a galaxy of antimatter that had a black hole thrown out of it so that it traveled intergalactically to encounter a normal matter black hole. That would be a very unlikely event, but theoretically an interesting question.

The force of gravity between the black hole and anti-black hole (defined as opposite electric charges and anti-aligned angular momenta) is still attractive. So, provided the electrostatic repulsion is not sufficient to counter act this, the two objects could collide.

 

Remember that a black hole "does not care what it eats", we have the no-hair theorem which tells us that (classically anyway) that a black hole is described by mass, electric charge and angular momentum. We cannot know if it has "eaten" antimatter or matter or even exotic matter.

 

Any black hole out there will have "eaten" plenty of matter, but also some antimatter.

is that possible that they would make a worm-hole.

Can anti-matter exist at the heat and pressure within a black hole?
