Is there a simpler way to describe the latest discrepancies or problem with the expansion of the universe. Does the rate of expansion consistently get faster and faster? I was reading this and had some questions. https://www.sciencemag.org/news/2019/07/debate-intensifies-over-speed-expanding-universe

    $\begingroup$ "Is there a simpler way to describe the latest discrepancies or problem with the expansion of the universe"? - The accelerating expansion is an interpretation based on the assumed FLRW geometry of the universe. However, the FLRW model is obviously incorrect, because it grossly mismatches observations. In particular, it mismatches the observed matter content in the universe by no less than 95%. This model also contradicts General Relativity and requires a modified gravity with a "cosmological constant" added to the field equations for no other reason, but to make a bad model look better. $\endgroup$ – safesphere Feb 27 at 5:19

The modified Big Bang is the mainstream cosmological models and it describes the observations and data. Discrepancy means a comparison between old models and new models. The Big Bang resolves them.

The article you quote is talking of a discrepancy between measurements of the Hubble constant, and I have asked about it in the astronomy.se. The resolution will have to be by finding the difference in the models that calculate the Hubble constant. I suspect, since the discrepancy between the various measured values is with the number derived from the Cosmic Microwave Radiation, which has a lot of hypothesis , thermodynamic and particle physics entering, those calculations will have to be rethought. I was asking whether the baryon asymmetry is taken into account in the CMB calculations.
