A Time Slice of Mathematical Cosmology

Abstract: Mathematical cosmology is the branch of theoretical physics where some of the most intricate, complex, and deeply unresolved issues lie. Beginning with Einstein’s static universe in 1917, in this brief paper we freely float above all major developments that shaped the field until today. We discuss highlights that are further documented in the authors’ recent survey “100 years of mathematical cosmology” scheduled to appear in the Theme Issue “The Future of Mathematical Cosmology.” This Theme Issue is to be published in two parts by the Philosophical Transactions of the Royal Society A, and contain a number of important contributions by key researchers in the field. © 2022, Pleiades Publishing, Inc.
