Let's assume we have a black hole with a net charge Q. If this charge is a substantial value, wouldn't this imply different event horizons for particles of different charge values? Wouldn't there be a black hole charge to mass ratio where the event horizon completely disappears for particles with the opposite charge sign? If so, doesn't this imply you could "feed" a black hole until its Q is such that the event horizon for certain particles disappears, and one could probe the singularity directly? Example: I have a black hole of 10 solar masses, and a charge of +10^12 coulombs. Electrons fall into the black hole easily, while protons can travel much closer to the center before falling in. Thoughts?
