A great review of Einstein’s contributions to cosmology.
Understanding the history of a field is essential to understanding the evolution of ideas therein. I had not realized how rigorous Einstein had been in deriving his cosmological models. It is much rewarding to reflect upon how Einstein abandoned a static model of the cosmos. The review also explains how the emergent universe idea makes use of Einstein’s cosmology.
It is mind bending and required reading. Enjoy.
