Analysis of Global Time Dilation — •Yang Jacky1 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 global concept of time. Firstly, we use the global flatness of space, in order to derive a global uniform evolution of time. Thereby, we use the ΛCDM model with a homogeneous universe.
Secondly, we extend that theory by heterogeneity. For it, we apply the linear growth theory. As a theoretical tool, we use the volume dynamics, see Carmesin (2024).
Thirdly, we analyze the data of the Hubble tension, in order to derive a global time evolution therefrom.
In all cases, we evaluate the age of the universe. Thereby, we use cosmological parameters achieved by the Planck collaboration (2020).
Fourthly, we analyze the global time evolution by comparing and critically discussing the above three methods.
