A recent arXiv paper by Capozziello et al (27 Feb 2023) claims:
the H0 tension is not due to neither systematic errors, nor to some new physics beyond the $\Lambda$CDM model, but simply to the fact that, in measuring the same quantity at different redshift, different results arise thanks to the look-back time evaluated at different epochs.
Now, maybe the solution is really this "simple", and I might be missing something, but I thought the age of the universe/lookback times depend on input cosmological parameters, including the Hubble parameter, i.e., just the redshift isn’t enough. I am noting this paper claims the age of the universe by Planck collaboration was derived without using $H_0$ via six independent parameters.
How can the Capozziello et al claim stack up?
It would seem to me to be a reheated version of this claim by the same author.
