Phys.org again printing anything that's sent their way...I get tired of the endless drivel from phys.org

Dark mind over dark matter, amirite?

[โ€“] [email protected] 12 points 5 months ago* (last edited 5 months ago) (1 children)

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.

Tired light is the flat earth of astrophysics/cosmology.

Does it really say it? Can you please quote the piece?

[โ€“] [email protected] 25 points 5 months ago (4 children)

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.

These type of comments always throw me through a loop.

Scientist:

Makes hypothesis, does analysis, writes paper, and presents work for other academics to review.

Lemmy poster:

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.

Thats not what the posting claimed to be. You missunderstand. Either intentionally or just as a fact.

[โ€“] [email protected] 4 points 5 months ago (1 children)

I get what you're saying, but peer review isn't exactly all that rigorous either

[โ€“] [email protected] 4 points 5 months ago* (last edited 5 months ago)

They meet the bare minimum of at least being a peer in their field of research.

[โ€“] [email protected] 3 points 5 months ago

I'm a workshop kind of guy that enjoys space documentaries. For my part, I see "dark matter" as a known hole in our current understanding of cosmology, and I bet when we figure out how it does actually work it'll lead to some really cool TV shows.

If light got tired, wouldn't everything get blurry the further away it were?

[โ€“] [email protected] 7 points 5 months ago (1 children)

I'm nearsighted, so that happens anyways

[โ€“] [email protected] 4 points 5 months ago

Me too but I always knew that it was my eyes not the maximum draw distance of the universe that was to blame.

[โ€“] [email protected] 6 points 5 months ago (2 children)

Couldn't the same be said for the proof of dark matter?

They were able to make some observations fit with their theory with dark matter yes, but not all of them

[โ€“] [email protected] 9 points 5 months ago

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.

[โ€“] [email protected] 9 points 5 months ago

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

[โ€“] [email protected] 0 points 5 months ago

Dicks out for dark matter!

[โ€“] [email protected] 3 points 5 months ago (1 children)

Is anyone really surprised? Really neat study though!

[โ€“] [email protected] 1 points 5 months ago (1 children)

A neat study... which you know literally nothing about? How can you possibly know it's neat?

I'm just built different
