This model has been in testing for 3 years and it passed all tests so far.
It already past sevral test and it solves a lot of problems that require dark energy or matter. And problems introduced by the James Webb telescope. It also confirmed cosmic chronometer findings on the expansion history.
It does not disprove models, it just shows that dark matter and energy are not needed and explains why we can’t find them.
Isn’t CERN now using mistral to help them sort the data out of the noise which is helping discover new particles? The partnership was just announced one month ago so it probably hasn’t resulted in anything yet.
