# Violation of the Law of Conservation of Charge in black hole?

Hey I'm a noob to physics however after reading about black holes and Hawking radiation. If a black hole made entirely out of negatively charged particles (say this black hole is made entirely of electrons) Then when it evaporates equal parts positive and negative particles (positrons and electrons for this example) are created. Doesn't this violate the law of conservation of charge?

• Why do you think equal positive and negative charges would be produced? – Dale Jun 5 at 17:02
• When charged virtual particles are created at the event horizon would it not be equally likely that the position falls in as that the electron falls in, meaning that on average 50% of the time positrons are made and 50% of the time electrons are made – tms Jun 5 at 17:22
• I am not sure, but I suspect not. I suspect that the negatively charged antiparticle would be electrostatically repelled from the black hole and the positive antiparticle would be electrostatically attracted back into the black hole. – Dale Jun 5 at 17:47

• It's best to think of the electromagnetic field of a charged black hole as existing outside the event horizon. See math.ucr.edu/home/baez/physics/Relativity/BlackHoles/… Also, Hawking radiation is almost entirely photons, until the BH is tiny. It takes a lot of energy to create an electron or positron, and the Hawking radiation of a stellar mass black hole is rather feeble. – PM 2Ring Jun 6 at 5:03

• @annav Nothing "resides" in a singularity. A singularity is not a "place" and not an "object". The attraction does not go as $1/r$, because $r$ inside the horizon is time. While you are inside, there is no horizon, because it is in the past and no longer exists, and there is no singularity, because it is in the future and does not "exist" yet. So a singularity cannot attract anything, whether gravitationally or electromagnetically, because, again, there is no singularity in any spatial direction around you, so there is nowhere to be attracted to. – safesphere Jun 6 at 7:19
