Physics is ultimately a work of the imagination. Over time some of those imaginings are retained and studied while others are dismissed or forgotten for lack of evidence and other times for reasons of fashion or politics and religion. Physics is not out there, it lives in you. Harry > A charged black hole is a black hole that possesses electric charge.
