abstract
I motivate a proposal for modeling, at weak string coupling, the ``Big Bounce" transition from a growing-curvature phase to standard (FRW) cosmology in terms of a pressure-less dense gas of "string-holes" (SH), string states lying on the correspondence curve between strings and black holes. During this phase SH evolve in such a way that temperature and (string-frame) curvature remain $O(M_s)$ and (a cosmological version of) the holographic entropy bound remains saturated. This reasoning also appears to imply a new interpretation of the Hagedorn phase transition in string theory.

Viscosity in Isotropic Cosmological Backgrounds in General Relativity and Starobinsky Gravity
Shear viscosity does not affect the background expansion or the electromagnetic luminosity distance in isotropic cosmologies with a comoving fluid, also in Starobinsky gravity.
