What happens when charged particles fall into a black hole?
Say like N electrons fall in, giving the black hole a net charge of -N.
Since light cannot escape the event horizon, I imagine electric fields cannot either, since they are mediated by photons.
So is that charge effectively lost until the black hole decays?
Or is there some kind of compensation mechanism with the virtual particles near the event horizon such that N positrons are pulled out of the vacuum, into the black hole to neutralize the net charge, and N electrons are ejected into space? This would conserve charge outside the black hole. Thanks.
