Query: Universality of the shear viscosity in supergravity   Kovtun, Son and Starinets proposed a bound on the shear viscosity of any
fluid in terms of its entropy density. We argue that this bound is always
saturated for gauge theories at large 't Hooft coupling, which admit
holographically dual supergravity description.
