    Graduate Can Black Holes Decay and How Does This Affect Their Event Horizon?

    http://www.superstringtheory.com/blackh/blackh3.html the URL above says that black holes can decay, but I don't understand, if the black hole sucks in an antiparticle and the particle gets ejected in the opposite direction, doesn't the event horizon of the black hole stay the same? How does it...
