The article is by Rajendra Gupta, Adjunct professor Physics @ L’Université d’Ottawa/University of Ottawa

First few lines:

Do constants of nature — the numbers that determine how things behave, like the speed of light — change over time as the universe expands? Does light get a little tired travelling vast cosmic distances? It was believed that dark matter and dark energy explained these cosmological phenomena, but recent research indicates that our universe has been expanding without dark matter or dark energy.

Doing away with dark matter and dark energy resolves the “impossible early galaxy problem,” that arises when trying to account for galaxies that do not adhere to expectations regarding to size and age. Finding an alternative to dark matter and energy that complies with existing cosmological observations, including galaxy distribution, is possible.

“We need to consider alternatives to dark matter that better explain cosmological observations” (see comments for discussion)

    Happy to hear you’re enjoying the work of talented scientists!

    As a non-layman, there isn’t any observations or theories that I know or that would support your cool idea, but as you say, we can always let the mind wander.

      Thank you. I really need to get a sub at that documentary site I keep seeing in creator ads. YT used to have good full docs, now its just click bait ai garbage and using known scientists images, except the ones like I mentioned they are great and try to stay to what is verified/verifiable.
