What happens when black holes collide? | EXPERT ANSWERS PHYSICS GIRL QUESTIONS

Why do we assume more anti particles fall into a black hole than matter particles. Would not Hawkins radiation be equally both anti matter and matter thus have zero effect on the black holes mass?

Even if more anti particles fall in the energy is still trapped in the black hole so it’s energy/mass would only get bigger not smaller?

For black holes to evaporate you have to be able to destroy energy/mass .
