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.
Very cool! I’m no expert in cosmology but I was familiar with some if the evidence for dark matter, namely rotation curves, and its really cool to hear about plausible alternate theories.
