Re-thinking the Age of the Universe

The oft-cited 13.8 billion years as the age of the universe depends crucially the `standard model’ which we believe to be incorrect. It also needs both dark energy and dark matter components. We have argued in George and Johansson (2021, 2023) that neither dark matter nor dark energy nor alternative theories of gravity are needed to explain the astronomical observations. In this presentation we focus on the particular question of the age of the universe. Our theory implies that the Hubble parameter at any time is given by H(t) = V_r/D = 1/t where t is any time after the beginning. More importantly t is related to z, the shift parameter, by t/t_o = 1/(1+z), where t_o is the present time (or age of the universe). This yields the simple relation H(t) / H(t_o) = 1 + z. This relation is shown to be in excellent agreement with observations detailed by Yu et al 2018. The optimal choice is H_o = 63.4 which corresponds to the age of the universe as 15.4 billion years. This greater value is consistent with all the recent observations of JWST and the other older anomalies (e.g. Methuselah star). Other aspects of the WKG/TGJ theory are also consistent with the JWST results.
