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.

If you knew it was bullshit, why did you post it? Shame on you

Well I didn't, I'm not an expert in this topic. The article was written by an adjunct professor at uOttawa, so I judged it higher than the other pop science articles I come across.

I considered deleting the post, but since I still don't know if the content is completely false (disinformation) or just academic discussion, and since the comment section has good discussion, I left it up.

I can edit the title if that helps, maybe

I didn't know about this particular xkcd till now, and it's funny because of how relevant it is to this exact situation
