Wissenschaftler in Tokio haben möglicherweise den ersten echten Beweis für dunkle Materie entdeckt. Ich bin so glücklich, in der Zeitleiste zu sein, in der wir das erste Bild eines Schwarzen Lochs und möglicherweise die Bestätigung der Dunklen Materie haben. Ich komme nicht darüber hinweg.

Is the link in the room with us?
So uh wee is the link because I dont see it
I’m looking around and I see no link
[Scientists may have finally ’seen‘ dark matter for the 1st time | Space](https://www.space.com/astronomy/dark-universe/scientists-may-have-finally-seen-dark-matter-for-the-1st-time)
This is a google AI summary, right?
I think we are going to get more evidence of dark matter during the rest of the century. But I am hoping timescape cosmology keeps getting more evidence doing away with dark energy

We possibly discover the secret ingredient to the universe and we call it “wimps” 😂
I’m trying to find the text of the study. I can not wait to see what kind of research and discoveries this might lead to if true.
Here is the spicy picture: [https://hips.hearstapps.com/hmg-prod/images/gamma-ray-image-of-the-milky-way-halo-6925f972bf1cc.jpg?resize=640:*](https://hips.hearstapps.com/hmg-prod/images/gamma-ray-image-of-the-milky-way-halo-6925f972bf1cc.jpg?resize=640:*)
For everyone confused where the links are, I posted multiple in the comments when I posted the original post but for some reason they’re not showing up for everyone but they’re on my page in my comments, here is one of them https://www.space.com/astronomy/dark-universe/scientists-may-have-finally-seen-dark-matter-for-the-1st-time
Can we call them something other than WIMPs?
WIMPS
So it was shy or scrady cat or something?
That’s a big ‚may have‘ which means nothing to the scientific community. Headlines like this contribute (rightly so) to the distrust of media and science.
Have we really regressed to the point where an unsourced AI summary is content?
Yes I definitely know what this all means
The 511 kev annihilation radiation theory has been floating around for at least a decade at this point. The problem isn’t seeing it, it’s proving that dark matter can actually cause it and it’s the true source.
Aligning the emissions to the halo isn’t enough unfortunately and previous examples have also had problems completely eliminating possibilities.

Its a 2-3 Sigma detection, not sufficient to claim anything
reminds me of the Nancy Grace Roman Space Tlescope which’ll be launching soon. that’ll help break more ground with dark matter.
There’s a joke in there about people having such a huge backlog of shows to watch these days, but I can’t seem to find it.
What would this mean to us. Is there anyway we could use this in the tech industry?
Can someone explain this to me like I’m 5?
Why is dark matter such a big deal and what can we learn from it?
We are living through the next step.
So from my quick read through the paper, It looks like this is just a paper trying to make sense of the excess in the galactic diffuse gamma emission. I don’t think this is a discovery of dark matter, just a lot of data being fit to a model that may or may not be covering all details. There are many papers on the various excesses seen around the galactic center and its neighboring regions and all of them with wildly different morphologies. I haven’t spent enough time reading this one to say how novel this idea is.
May. Perhaps. Could. For such smart people, scientists are never certain enough to say for sure but always leave themselves an out. Guess their government grant is up for renewal and time to put out a clickbait announcement so they don’t have to get real jobs
Common, it’s meaningless fluff
For a century we’ve had to just make do with doesn’t matter.
I’m an astro-particle physicist. This is NOT a discovery of dark matter. In fact, from the summary, this just looks like a re-analysis of a signal we’ve known about for ~15 years. The Fermi telescope detected an excess of gamma rays relative to models physicists have constructed of expected galactic diffuse gamma-ray emission. This excess is potentially consistent with annihilating WIMP dark matter… or some other astrophysical source that is difficult to resolve, like pulsars in the galactic center. The other option is that the models that physicists have been using for these comparisons aren’t fully correct (this is actually what my current research focuses on!)
Sorry, if this is a dumb question. But isn’t it possible this is something totally different, not even theroiszied yet, and they are simply trying to say it dark matter.
I remember there have more than a few things they said this is dark matter, or this is because it’s being affected by dark matter, and only find out… nope it was something else.
Where’s that cool Astronomer dude to weigh in and explain the significance of this for us simpletons
Someone please explain how this couldn’t just be that the electron population or radiation field is mismodeled in a way that leaves a halo-shaped residual peaking around ~20 GeV?
