  Relativistic fluid hydrodynamics, organized as an effective field theory in
the velocity gradients, has zero radius of convergence due to the presence of
non-hydrodynamic excitations. Likewise, the theory of elasticity of brittle
solids, organized as an effective field theory in the strain gradients, has
zero radius of convergence due to the process of the thermal nucleation of
cracks. Viscoelastic materials share properties of both fluids and solids. We
use holographic gauge theory/gravity correspondence to study all order
hydrodynamics of relativistic viscoelastic media.
