This question already has an answer here:
I seem to misunderstand the whole concept of calibration bosons.
Let`s imagine a charged black hole. It does not let out anything that travels at any speed less than or equal to the speed of light, right?
So how can we even know the black hole is massive and it has a charge if nothing (which also includes all force-conveying particles) can be faster than light?
Okay, for quantum gravity there is no conclusive theory as of now, and the graviton is yet to be discovered experimentally. But what about the electric charge?
