Vafa and Scaling Symmetry
The word conformal we've been throwing around a lot. Is it good enough to think about that as a scaling symmetry? Like you zoom in twice as much and the system looks the same as it did at your original zoom. That's all conformal means. Things look the same on all different length scales. It was just like there's a speed limit to the black hole rotating. There's also a certain amount of charge you can put in a black hole. And am I right to say that you look at that limit in a certain number of dimensions with supersymmetry and everything? That's right. We looked at the limit.
