Cosmology, Black Holes and Shock Waves Beyond the Hubble Length
Joel Smoller, Blake Temple
We construct exact, entropy satisfying shock wave solutions of the Einstein equations for a perfect fluid which extend the Oppeheimer-Snyder (OS) model to the case of non-zero pres…

Cosmology with a shock wave
Joel Smoller, Blake Temple
We construct the simplest solution of the Einstein equations that incorporates a shock-wave into a standard Friedmann-Robertson-Walker metric whose equation of state accounts for t…
