Hi(adsbygoogle = window.adsbygoogle || []).push({});

I have few questions about charged BH.

1 I dont understand why the equations for the charged BH are different from BH without a charge. Why the gravitation, infinitely strong at the horizon, should 'care' about such minor additional forces like the electrical attraction/repulsion. Anyway, horizon is a point of no return as singularity becomes in the future for a free falling observer, no matter if he is charged or not. Additional electric repulsion would not 'save' the falling observer at the horizon.

2 Electron is orbiting a positively charged BH. QFT describes this attraction as exchange of virtual photons. But how can they pass thru the horizon?

3 Can BH have a color charge? Why not? Say green-antigreen u or d virtual quark pairs are torn abart at the horizon. What happens next?

Thank you
