Hi bfancis, so do you mean by wide relativity, a speed of light faster than our speed of light, such as that which existed at the explosion of the big bang? If so, it's another tool in the arsenal of simplification in our descriptions... I'd say it could be stated as, "Today's narrow relativity and the black hole's wide relativity, of the speeds of light." Sounds fine to me, and also matches Dave's black hole velocity differences, then and now, and mine, of radiation density variations of c over time...
