Consider if you will… …a large black hole, with an event horizon 1 light year in diameter. If an observer shoots an electron into the event horizon on one side, how long does it take for an observer on the opposite site of the black hole to register the increased electric charge and mass? Normally I’d say it would take 1 year. However, in that case it means that the black hole’s electric field and the shape of the event horizon are uneven during that time. It would mean that observers can make inferences about matter that has entered the black hole in the past by making careful observations of the shape of the event horizon, the electric field and the rotation. Is that possible? Or is the black hole a true singularity, and is the charge transmitted to the opposite site immediately? (spooky action at a distance).
