08.09.2017 / Jan. J. Ostrowski (Postdoc LIO, CRAL) : Cosmological backreaction conjecture : recent developments and future prospects

Inhomogeneous, relativistic cosmology has recently observed a rise in popularity among the scientific community. In particular, the scalar averaging approach has been intensively examined both analytically and numerically, giving some new insights into the problem of cosmological backreaction, i.e. the conjectured influence of small scale density inhomogeneities on the large scale evolution of the Universe. In my talk, I will summarise these recent efforts including the Green and Wald theorem and several results from N-body simulations, and I present future prospects of cosmological backreaction investigations.
