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)

    Wow, I’m actually really glad there’s an xkcd for this because I do get so tired of videos and articles click-baiting “Dark Matter is nonsense, finally a real alternative” and it’s always always always some variant on “maybe gravity is dynamic over distance/time/aether” or “maybe energy gets tired” or some other silly stuff that doesn’t fit all the data.

    At least invent some whackier new ideas! What happened to universe-long unbounded superstrings? Ultrafast orbiting cosmic mesons create relativity drag on galaxies? Maybe reality is shaped like a bowl of gravity-fruitloops floating in dark energy milk? Give me something fun to work with here, no wonder sci-fi sucks so much now!
