Is H0 a constant in ΛCDM?
Abstract: In physics, and science more generally, dynamical models specified by fitting parameters may only be valid in certain epochs. In short, any dynamical model with evolving or time dependent fitting parameters is no longer valid. I will apply this reasoning to the Lambda-CDM model and comment on whether the cosmological or fitting parameters evolve or not. The backdrop for this talk is H0 and S8 tensions where H0 is apparently smaller and S8 is apparently larger in the early Universe compared to the late Universe.
