Dr.Becky goes over this in a video [0] from a year ago about the divergent results obtained by the two main ways we measure the rate of expansion.
Cosmic Microwave Background Vs. Supernovae. As the accuracy of each method has improved, the end results have diverged.

- pigpang 3y agoUnfortunatelly, title of article on HN contradicts content of article, so many HN readers skip article because of "confirmed" (in other words: nothing new). IMHO, a Tired Light theory will better explain facts, but it will require paradigm shift, so there will be a lot of resistance before revolution.
- luc4sdreyer 3y ago> but it will require paradigm shift, so there will be a lot of resistance before revolution. I think the main point of resistance is the incompatibility with observations. All Tired light models have been falsified: https://en.wikipedia.org/wiki/Tired_light#Specific_falsified_models https://en.wikipedia.org/wiki/Tired_light#Specific_falsified... If you're aware of a model that can fit some or all of our observations, please share it!
- pigpang 3y agoI have my own theory, which is not disproved yet: gravitational background noise slow down light a bit. Gravitation affects whole stream of photons in uniform way, not individual photons. Moreover, it doesn't change direction of photons, so no blur or scattering. My napking maths, which I did few months ago, tells that gravitational delaying should case effect of same magnitude as in red shift, (I did calculation for one frequency only, for proper calculation I need to know the temperature of the noise).
