A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, and toxicity are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
Reminder: The terms of service apply here too.

Yeah, it's legitimate science being done, but some people treat it as sacred and would fight you to no end because they say Dark Matter is some certainty, rather than approaching it with the proper scientific skepticism or with a statistical outlook.
For the most part believers in Dark Matter are cool, but a vocal minority practically worship it as the only possible truth.
The certainty is that there is something there, we just don't know what it is. The name "dark" anything is irrelevant.
If a new hypothetical model showed that either some far off unobserved mass(es) or the currently observable mass can have the gravitational effects that were previously explained by dark matter, or any other far off idea about the nature of gravity at large scale: then there would be evidence there is nothing there. Currently there is no evidence that something is there, just that there are forces and motions that are not understood.
"just that there are forces and motions that are not understood." - aka, there's "something" there... Doesn't have to be a physical something. You're intentionally misunderstanding or misinterpreting just to try and win points on the Internet.
I mean, they are working on adjusting Newtonian dynamics for the situations where gravity between objects is low. This would fix the model for the strange galaxy spin and where 2 stars orbit eachother.
The issue with this is there are too many unknowns as we have a (relatively) fixed point of perspective. But statistical analysis is working on reducing the impact of those unknowns, and there is likely a paper published in the next few months regarding this.
Then, I guess it's a matter of understanding why this applies. And maybe it applies because of dark matter, and it all wraps back round to an undiscovered thing.
Or, perhaps Newtonian dynamics isn't complete but has been accurate enough to withstand all our testing (like taking 9.8 as the value of G on earth, even though it varies across the globe, and the moon/sun/planets also have a miniscule impact. For everything we do on earth, 9.8 is accurate enough)
Dark matter still has strong scientific support, although still undiscovered.
Modifying Newtonian dynamics has so far been disproven.
Both are worthy of pursuing
Okay I see what you mean, the meaning of your words missed me the first time, sorry. You're saying something is happening, not necessarily that something else exists to cause it.
