Analysis of the Evolution of Universal Time Dilation and Dark Energy — •Jacky David Yang1 and Hans-Otto Carmesin1,2,3 — 1Universität Bremen, Fachbereich 1, Postfach 330440, 28334 Bremen — 2Studienseminar Stade, Bahnhofstr. 5, 21682 Stade — 3Gymnasium Athenaeum, Harsefelder Straße 40, 21680 Stade
We analyze the concept and the universal/global evolution of time. Our elaboration uses the global Euclidean geometry of the universe. We model the universe on the basis of homogeneity (ΛCDM model) and of heterogeneity (linear growth theory). Measurement values of cosmological parameters are used, see Planck Collaboration (2020). Hereby, the model of the heterogeneous universe depends on the volume dynamics (Carmesin 2024). Thereby, we take care of the Hubble tension. The aim is the analysis of the universal time dilation. We transform the calculable H0 - values into calendar dates. Moreover, differences between respective times of both models are derived, in order to determine the time dilation. The results are presented by graphs, tables and formulas, so our results are visualized intuitively. Therefrom, the time evolution and the age of the universe are obtained, Furthermore, the time evolution of the dark energy ΩΛ is analyzed and visualized. It is derived from the time evolution of the universal/global time dilation.
