Day 48

Friday.  Hopefully have recovered from the all-nighter Wed-Thu.  Took all day to deal with German visa yesterday; today I hope to get the GGLens code running again, with the correct binning.

Toward physical cosmology: focus on inhomogeneous geometry and its non-perturbative effects

Buchert

He wants to construct a physical, fully relativistic cosmology, including influence of inhomogeneities on the effective evolution history of the universe.  Backreaction terms: influence of inhomogeneities in the effective evolution of the Universe; can be expressed through spatially averaged geometrical invariants; can be interpreted as energies of an emerging scalar field ("morphon").  Propose a strategy of phenomenological scalar field models can be traced back to inhomoegenous geometrical properites of space and its embedding into spacetime.


* Interesting theory on DM, DE and Inflation.  It is a review article.
