A book I read says that when virtual particle-antiparticle pairs are created near a black hole then sometimes one of the particle pairs will be captured by the black hole while the other one will be freed to move away as a real particle - then this causes the black hole to lose mass and thus evaporate.
How does it cause the black hole to lose mass if the particle captured by the black hole is a 'normal' virtual particle instead of the antiparticle of the pair?
I would think that the virtual antiparticle -once captured- might interact with all the normal matter inside the black hole to somehow reduce mass.
But if the captured virtual particle is a 'normal' or in other words not a virtual antiparticle then should not this cause the mass of the black hole to increase?
