I went and read the research.
I’m not an expert and as such can’t really analyze it fully. But what I took away is that it aimed to test a part of new theory by with a very narrow measurement, using early-universe density oscillations. They left dark matter out of the equation with the new model, and it was a smashing success if you’re willing to overlook that it requires the universe to be a completely different age than it is… In short, this is shenanigans.
edit: I’m fine being wrong if I am, I’d love to know more from informed readers. That’s just what I took away https://iopscience.iop.org/article/10.3847/1538-4357/ad1bc6#apjad1bc6s3
edit2: It also presumes the “tired light theory” is true. Tired light is the flat earth of astrophysics/cosmology. Yeah, there are contrarian knuckleheads in every discipline.

Does it really say it? Can you please quote the piece?
Don’t get too excited, this is a pretty fringe theory that doesn’t really have experimental evidence. They were able to make some observations fit with their theory without dark matter yes, but not all of them. The tired light part in particular has a lot of contradictions with observation that they don’t explain.
So interesting, but far from definitive.
If light got tired, wouldn’t everything get blurry the further away it were?
I’m nearsighted, so that happens anyways
Couldn’t the same be said for the proof of dark matter?

Generally for a new theory to be accepted, it needs to explain everything that the old theory did plus something more

No, dark matter is actually a great explanation for lots and lots of observations; the only problem with it is that we don’t know anything about it other than that it is such a good explanation for these observations.
These type of comments always throw me through a loop.

Logs into lemmy. Posts “i think not mr scientist”. Recieves upvotes.
While I would certainly like to say I understood any of this. This post has not met any rigorous standard of debunking the researchers findings.
It’s fine if you have knowledge on this particular subject but it kinda seems like you’re just throwing shade.
I get what you’re saying, but peer review isn’t exactly all that rigorous either
They meet the bare minimum of at least being a peer in their field of research.

Thats not what the posting claimed to be. You missunderstand. Either intentionally or just as a fact.
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
🥇
I guess it’s my turn to point out typo like a good grammar police. Eat is ate in past tense. Also you only have one r in sorry.
Anyway, now I shall head to another corner of internet to make my own typos so people can point them out
these typos were intentional
good luck on your typo making endeavors tho!
Dark mind over dark matter, amirite?
This model combines two ideas—about 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.
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.
At some point we may have to review some theories though. The idea that light would lose energy over extra long distances at least makes sense unlike some kind of latter that we can’t detect and we can’t figure out why it would either still be there but not more than it is.
This is kind of how time was supposed to be absolute. Einstein never received a Nobel for the theory of relativity because of how suspicious it seemed at the time.
There being a substance that does not interact with light at all doesn’t seem that far fetched to me. There is nothing in the laws of the universe that says “Humans must be able to detect everything that exists because otherwise it wouldn’t make sense.”
It feels entirely possible that we won’t be able to detect dark matter through any conventional means that we currently have.
It’s not about humans. It’s about science. “there is dark matter that doesn’t interact with matter” can as well be “there is magic, and I cannot be proven wrong”.
Dark matter does interact with matter, though: it interacts gravitationally. It just does not interact in other ways (that we know of yet). All you would have to do to disprove the existence of dark matter is to show that some things interact with it gravitationally but others don’t. However, this is not what we see; what we actually see is a whole bunch of separate things that all experience the effect of the existence of dark matter in the same way. It’s effectiveness as an explanation in this regard is exactly what makes it so difficult to dethrone.
Dark matter is exactly like adding a constant to your equation so that it fits the numbers.
If by “constant” you mean “3D distribution that explains not just one equation but lots of separate observations”, then sure, it’s just like that.
It’s almost like we shouldn’t have been all in on the thing that literally has less evidence behind it than fucking psychic powers.
They say, while being fully behind a hypothesis with no supporting evidence and while not understanding the research.
Is anyone really surprised? Really neat study though!
A neat study… which you know literally nothing about? How can you possibly know it’s neat?
I’m just built different
