Abstract

In the course of the history of cosmology, the Friedman-Lemaˆıtre-Robertson-Walker (FLRW) metric and Einstein's general relativity provided the basis for many theories in cosmology, including the one by James Peebles with the cosmological constant Λ, cold dark matter This theory, which describes the evolution of the universe, is known as the ΛCDM model, and the Mori-Zwanzig equation, the beginning point for scientists at the University of Münster's Institute of Theoretical Physics and Center for Soft Nanoscience to begin research that will give a strong theoretical foundation for characterizing systems with a large number of particles and a small number of detected particles. Although the first two the Friedman-Lemaˆıtre-Robertson-Walker (FLRW) metric and Einstein's general relativity are a century away from being formulated, we explain why we interpret the influence of the scale factor on the Friedman cosmological model, and the role it plays in the various equations and how it works by reviewing these milestones in cosmology.
