The existence of the most massive virialized objects can be used as a tool to study properties of the Universe, such as the nature of gravity and dark sector, as well as, the Gaussianity of primordial density fluctuations. In my talk I will show the predictions for the most massive objects in the Universe using the silent universe model (Einstein field equations with no rotation and energy...

The 'Big Rip' is a proposed hypothetical end to the universe where the Hubble parameter increases to infinity in a finite time. It assumes the universe contains a fluid ('dark energy' say) with an equation of state state w<-1 (pressure + density < 0). Caldwell et al give just 20 Gyr until the catastrophe, under assumptions including perfect homogeneity and isotropy, however we show...
