Are the best measurements to date deepening the “cosmological crisis”?

A continuing discrepancy between two measurements of the expansion of the universe is “forcing” a re-examination of the Standard Model, which physicists have hated for decades, mainly for philosophical reasons:

“The exciting thing is that if the discrepancy is due to new physics prior to recombination, it will almost certainly have distinctive signatures,” Lewis says. The signatures would show in the finer details of the CMB—something that the next generation of CMB telescopes, such as the upcoming Simons Observatory, could see.

Riess also thinks that the discrepancy is pointing fingers at cosmologists’ standard model. “At some point, you have to start saying the universe has another wrinkle in it, in the cosmological model—in the composition of the universe or in some feature of dark matter or dark energy—[that] could also potentially explain this,” he says. “You have to give that some serious consideration.”Anil Ananthaswamy , “Best-Yet Measurements Deepen Cosmological Crisis” at Scientific American

Two things many cosmologists would like to get rid of are the Big Bang and apparent fine-tuning of the universe. Telling a different story is difficult mainly due to lack of evidence for a different story but they can make do with discrepancies. But then maybe the years have made some of us cynical.

Discover: Even the best dark matter theories are crumbling


Researcher: The search for dark matter has become a “quagmire of confirmation bias” So many research areas in science today are hitting hard barriers that it is reasonable to think that we are missing something.

It all adds up under SPIRAL cosmological redshift hypothesis and model, where we find there has been no cosmic expansion subsequent to the cosmic inflation expansion epoch that was early in the history of the universe and the entire universe approximates the sphere that is the visible universe. www.amazon.com/dp/B0181C4Q1W SPIRAL Pearlman
Interesting article, but it says nothing that I can see justifies News' editorial comments. hazel
