There are many claims like this, and it’s hard to tell who’s right. Even the Nobel prize committee said fuck it and awarded the physics prize to some programmers
It’s usually pretty easy to tell which new theories can be discarded because they don’t explain all the observations that lead us to the dark matter theory in the first place (like e.g. the Bullet Cluster). Or it would be easy if media wasn’t full of uncritical clickbait fluff pieces like this that rather make sensationalist claims than contextualizing how a new study fits into the existing science.
It’s interesting that the article mentions them looking for tests, yet doesn’t mention applying the theory to things we’ve already tested with other predictions. The Bullet Cluster, for example.
That seems really suspect to me. It would seem ‘a given’ to run the hypothesis against that which is already measured to validate it, or not. But to ignore established metrics and go out looking seems to be a fish looking for fishermen.
So far this is just a hypothesis, with no empirical evidence to back it up. On the other hand the standard model is supported by lots of evidence. It says this pretty clearly at the bottom of the article.
It’s possible this guy is right but he has a long way to go to prove it. Extraordinary claims require extraordinary evidence, as Carl Sagan would say.
At a superficial level, sure. But that’s in large part because of the nature of the problem. Dark Matter is the quintessential Unknown Unknown. It comes from the argument that we have a universe that is accelerating in its rate of expansion in a way that doesn’t follow the understood shape of the universe.
Dark Matter / Energy solves the problem by positing a large invisible mass that’s been compressed, like a spring, and is still being released following the Big Bang, propelling SpaceTime out in front of it.
But because all our measurements are occurring in a relatively small timeframe (relative to the history of the universe) and because we’re working from a very limited perspective (not like we can pop over to the other side of the universe and confirm our findings), we have to make a lot of estimates and assumptions. Introducing/Dismissing some of these assumptions can “solve” certain problems very easily. But on closer inspection, they raise a bunch of new questions that can just as easily be debated.

That’s more because AI is “hot” right now and astrophysics isn’t paying anyone’s bills.
I think you’re conflating dark matter and dark energy, they are two different things. Dark Energy is what’s accelerating universal expansion. Dark Matter slows it down.
and I would actually classify them as “known unknowns” since they are holes in our understanding of physics that we’re aware of. A true unknown unknown wouldn’t be in scientific discussion at all or have even been given a name; it would be completely off our radar.

It’s probably not these guys, since I’m pretty sure nobody believes the “tired light” hypothesis.
