This stuff is way, way over my head. And probably most of humanity right now. In this moment I can feel some envy and admiration towards whoever is around to understand the great breakthroughs we may one day have on this matter.

Only white matter is allowed in this universe.
Just going to assume this popular science article is about a theory with no support as usual.
Always has been.
um i browsed it for nearly two minutes and at the very top of the page there was clearly a chart. i didn't understand it but obviously we can conclude that it is based on scientific science

*hypothesis. A theory (in the scientific sense) has to be tested and therefore has at least some support!
Fair.
sory i eated it all
where were u wen dark matter die
i was sat at home eating milky way when saturn ring
"dark matter is kill"
"no"
when saturn ring

Glad someone appreciated that, lol

It's time for people to start taking this matter lightly.
Well played.
"In standard cosmology, the accelerated expansion of the universe is said to be caused by dark energy but is in fact due to the weakening forces of nature as it expands, not due to dark energy."
Fascinating! I'm looking forward to seeing where this goes. The "tired light" theory they mention doesn't seem to have held up to scrutiny, but maybe there's something else about weakening over time or distance that we haven't observed yet.
How would the gravitational forces weakening accelerate the expansion speed? It would at best "not slow it down", you can't explain the speed increase with this logic. That just sounds wrong. Am I missing something?

This model combines two ideasβabout how the forces of nature decrease over cosmic time and about light losing energy when it travels a long distance. It's been tested and has been shown to match up with several observations, such as about how galaxies are spread out and how light from the early universe has evolved.
These hypotheses never seem to stand up to rigorous analysis. Still, always welcome the discussion.
This is the same researcher that said the universe is 26.7 billion years old based on the JWST data instead of 13.8.
Happy to see ideas thrown out there to help us understand what dark matter is, but I'm really looking forward to all the random videos that eventually come out explaining why it holds up against a whole bunch of observational evidence while it ignores all the other observational evidence it doesn't hold up against.
Absolutely. On the one hand, having ~26% of the known universe consisting of a substance that we cannot detect directly leaves a lot of questions open. On the other hand; dark matter is postulated because otherwise things like galaxy rotation curves don't match what we believe they should be from general relativity, and this theory doesn't seem to address that.

Also, light 'losing energy' would be a violation of the first law of thermodynamics, unless it loses it 'to' somewhere.
Light does actually just lose energy to nowhere in our current understanding of expanding space.
