The data are well-reproduced by perfect fluid dynamics. A calculation of the dimensionless ratio of shear viscosity $\\eta$ to entropy density $s$ by Kovtun, Son and Starinets within anti-de Sitter space/conformal field theory yields $\\eta/s = \\hbar/4\\pi k_B$ which has been conjectured to be a lower bound for any physical system.
