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.
But I could swear I saw a report where a guy detected dark matter a long time ago.
There were probably a bunch of caveats attached to it I didn’t pick up on.
If they can detect it, then it’s not dark matter.
Sure, probably true. We’ve detected a lot of dark matter actually! Based on a bunch of things, we expect the universe to have more matter than we actually observe. Dark matter just refers to any mass that falls into that category of “previously unobserved”. So as we discover that there are more black holes than we thought, as our telescopes become capable of detecting extremely dim brown dwarves, and as we discover new subatomic particles, we chip away at dark matter, finally shining a light over previously hidden areas of our universe.
But there’s still more unaccounted for.
